Inline gearbox for automobile application

The rapid development of life has made the car gradually enter people's lives, and now life is more and more humanized. Many young friends like to modify the car to reflect the personality of their car. In the car modification, there is a modified car. The interior, the sound, the appearance, and the straight-through, then do you know what are the advantages and disadvantages of the car? Let's take a look!

Speaking of the modified car, the first impression is the word "fried street". Why is it that the street will be blown up and the exhaust gas will not be too much? Let's talk about exhaust modification this time. When it comes to exhaust gas modification, everyone will say that to improve the power, or to change the sound, it is true that the modified exhaust will improve the power, but also to deal with the road conditions and personal driving habits to modify. Exhaust gas is divided into: head section, middle section and tail section, while the tail section is divided into M drum and straight row dru

Then we talk about direct exhaust, if you use the straight exhaust to replace or remove the three yuan, the middle tail is replaced by straight, it really will increase the strength of the high turn, but the low twist will be very weak, driving in the city The district is very fuel-intensive, and even the MT-type car is more difficult to drive; but if it is opened at a high-speed or urban loop, this is undoubtedly a horsepower boost compared to the original car exhaust at high speeds. The resistance is gone, and the natural exhaust sound will also swell.
The back pressure exhaust is the exhaust of the original car, and it will take care of the good opening. The back pressure exhaust is very good in low-torque performance, so walking in the urban area is very comfortable and feels powerful; but if you go High-speed, high-speed, because of his large exhaust resistance, affecting the engine work, so you can not get the most out of it, so there will be a feeling of squatting. Because the back pressure exhaust gas under the action of muffler cotton and ternary, the movement is much less than the straight row.

The so-called direct HI exhaust (also known as direct exhaust, straight through exhaust), that is, from the exhaust manifold, remove the catalytic section catalyst is an environmentally friendly material) and the tail row, directly discharge the exhaust gas into the narrow gas. The discharge effect of the direct exhaust gas is more suitable for long-distance running high-speed and racing track. The sound is generally above 100 decibels, and the vibration feeling is also obvious when the car is running. At the same time, the untreated exhaust gas will cause serious pollution and increase the height. Speed ​​horsepower.
The low and medium speed ugly forces are not satisfactory and will lose a certain amount of torque. The modified direct exhaust pipe generally increases the noise and the exhaust gas exhaust exceeds the standard. The straight-out acceleration will be better than the back pressure tube, but the biggest disadvantage is that it is very noisy. It will make the traffic police come to soap. The back pressure is very low, the exhaust has no resistance, the low-speed torque is poor, and the Chinese-language speed is stronger. Big. The advantage is that the exhaust is smooth, the high speed torque is strong; the disadvantage is low speed soft power, high noise and large volume.
To change the straight line is to make the exhaust more smooth, and it will help the horsepower. Of course, there is not much improvement, especially for small-displacement cars. The sound of the straight words that are changed is more pleasant. Of course, if the change is not good, it will not only have no advantage but affect the car's own power. Moreover, the exhaust emissions of the straight exhaust gas are not up to standard.

Worm gear reducers are widely used in various fields. It has developed into four major categories of products, including worm gear reducers, gear reducers, hardened gear reducers, and continuously variable transmissions. According to preliminary statistics, the industries with large worm gear reducers are mainly: electric machinery, metallurgical machinery, environmental protection machinery. , electronic appliances, road construction machinery, chemical machinery, food machinery, light industrial machinery, transportation machinery, construction machinery, building materials machinery, cement machinery, rubber machinery, water conservancy machinery, petroleum machinery, etc.

The number of gearbox products used in these industries has accounted for 60% to 70% of the total number of gearboxes used in various industries across the country. In addition: In the current mechanism for transmitting power and motion, the range of applications of the reducer is quite extensive, and it can be seen in almost all kinds of mechanical transmission systems, from vehicles to ships, cars, locomotives, and buildings. Used heavy machinery, processing equipment and automatic production equipment used in the machinery industry, household appliances, clocks, etc., which are common in daily life. Applications ranging from large power transmission work to small loads, precise angular transmission can be seen in the worm gear The application of the reducer, and in industrial applications, the worm gear reducer has the function of deceleration and increased torque, so it is widely used in speed and torque conversion equipment.


The reducer is a kind of power transmission organization. It is indispensable in the dust removal system. It uses the speed converter of the gear to decelerate the number of revolutions of the electromechanical to the required number of revolutions and obtain a large torque organization.

In today's organizations that transmit power and motion, the use of reducers is very wide. It can be seen in the transmission system of various types of machinery, from ships, cars, locomotives, heavy machinery for construction, processing equipment and automatic production equipment used in the machinery industry, to household appliances that are common in daily life. , wall clocks, etc. It can be used from a large power transmission operation to a small load and accurate viewpoint transmission. In industrial use, the reducer has a deceleration and added torque function, and is a conversion device widely used in speed and torque.
In theory, the maximum working torque required by the user must be less than twice the additional output torque of the reducer. In particular, it is necessary to strictly abide by this principle in some applications. This is not only the maintenance of the reducer, but also the prevention of deceleration. The output shaft of the machine is twisted. This is mainly because if there is a problem with the equipment, the output shaft of the reducer and its load are stuck. At this time, the overload of the drive motor will still increase its output, and thus the output bearing of the reducer may be affected. The force exceeds twice its extra output torque and the output shaft of the reducer is broken.
The car provides a common example of gear reduction. The internal combustion engine must operate at high speed to maintain smooth power generation. When the vehicle is stopped, decelerated or slow to travel, if applied directly to the wheel, the speed of the engine will cause the wheel to rotate or the vehicle to increase speed or even lose steering control. By using a gear reducer, energy can be used to overcome the inertia of the stopped vehicle, reduce the momentum of the deceleration vehicle or allow the heavier load to be drawn at a lower speed.

The selection of faults results in insufficient output of the gear unit. Some users mistakenly believe that only the additional output torque of the selected reducer can satisfy the operation requirements. In fact, the first is that the additional output torque of the motor is multiplied by the reduction ratio, and the obtained value is in principle smaller than The additional output torque of the similar reducer supplied by the product sample, together with the overload of the drive motor and the maximum working torque required in practice.

The reducer is divided into high-power reducer and low-power reducer (micro reducer), which are used in different fields; for example, the small reducer (outer diameter 38mm, voltage 24V) of Zhaowei Electromechanical is used in small equipment:

The reducer is a relatively precise machine. The purpose of the reducer is to reduce the speed and increase the torque. The reducer plays a role in matching the speed and transmitting torque between the prime mover and the working machine or the actuator. It reduces the motor (motor) speed through mechanical transmission, and saves energy by reducing the motor speed through the inverter.

According to the different transmission stages, the reducer can be divided into single-stage and multi-stage; according to the shape of the tooth factory wheel, it can be divided into cylindrical gear reducer, bevel gear reducer and cone-cylindrical guide reducer; Can be divided into expansion, split and the same axis reducer.

The reducer is generally used for transmission equipment with low speed and high torque. The motor, internal combustion engine or other high-speed power is driven by the gears with few teeth on the input shaft of the reducer to mesh the large gear on the output shaft to achieve the purpose of deceleration. The reducer will also have several pairs of identical principle gears to achieve the desired deceleration effect. The ratio of the number of teeth of the large and small gears is the transmission ratio.

At present, the technical level of most of China's reducers is still not high, and the transition of new and old products will take a long time. The reducer is a mechanical transmission device in many fields of the national economy. The product categories involved in the industry include various types of gear reducers, planetary gear reducers and worm reducers, as well as various special transmission devices, such as speed increase devices and speed control. Devices, and various types of composite transmissions including flexible transmissions. The product service application fields of reducer (reducer) involve metallurgy, nonferrous metals, coal, building materials, ships, water conservancy, electric power, engineering machinery and petrochemical industries.

China's gearbox industry has a history of nearly 40 years. In all areas of the national economy and the defense industry, reducer products have a wide range of applications. Food light industry, electric machinery, construction machinery, metallurgical machinery, cement machinery, environmental protection machinery, electronic appliances, road construction machinery, water conservancy machinery, chemical machinery, mining machinery, transportation machinery, building materials machinery, rubber machinery, petroleum machinery and other industries Reducer products have strong demand.

The market with great potential has spawned fierce competition in the industry. In the brutal market competition, enterprises in the gearbox industry must speed up the elimination of backward production capacity, vigorously develop high-efficiency energy-saving products, make full use of the national energy-saving products, benefit the project policy opportunities, and increase product renewal efforts. Adjust the product structure and pay attention to the national industrial policy to cope with the complex and volatile economic environment and maintain a good momentum of development.

There are three ways to load the metallurgical equipment, namely, the tank type, the material truck and the belt conveyor. Among them, the belt conveyor feeding system has the most advantages, which not only can make the storage tank and other facilities far away from the blast furnace, but also has large feeding capacity, is very flexible and extremely efficient, and has a low damage rate to the charging material. In addition, the belt conveyor loading system can help reduce the weight of the equipment and simplify the control system.

In recent years, due to China's active and stable monetary policy, the investment in fixed assets has increased, and the industries of transportation, construction, machinery, and national defense have received great support, which has driven the gearbox industry to maintain a good growth rate. The machinery manufacturing industry of the reducer belongs to the basic equipment industry of the national economy, and its development has long been closely related to the national macro economy. With the improvement of industrial production level, management mode, marketing mode, product output and export delivery value in recent years, the industry has also promoted the balanced cooperation of the industrial chain, which has gradually integrated the gear reducer industry into the high-end industrial chain. In the chain, it has become a pioneering industry for independent innovation.

China's reducer industry has entered the high-end application field, which means that in terms of technical capabilities, China has been internationally recognized in the frontier of socialized production and innovation, but today's achievements have become the new technology innovation concept and product development of China's reducer enterprises. Stand on the ground. For a long time, most of the products in China's reducer industry are at the low-end technology level. To enter the wind power, nuclear power and aerospace industry supporting equipment, it must meet the requirements of international high-end products. At present, the Tyrone reducer has already entered the international brand. The qualification has won the trust of many reducer application units and suppliers at home and abroad, which indicates that China's high-end products and equipment of reducer have achieved a major historical turn from import to export.

China's domestic reducer enterprises have existed in various situations for a long time. There are various economic associations such as foreign capital, joint-stock system, and Sino-foreign joint ventures. The gap between product renewal and R&D has not fully utilized the technology sharing advantages of foreign capital in recent years. Large, and relatively uncomfortable with the market demand, led to the majority of independent innovation products are versatile products, giving foreign companies a lot of opportunities to seize the domestic high-end market, which is urgently needed to change. Therefore, the reducer industry should learn from foreign-funded enterprises in terms of development model and management innovation, especially in the planning of market segmentation areas, to realize the modularization of its product structure, the embedding of technology, and the establishment of an open growth model. To make the industry look in the direction of standardization and standardization.
Harmonic gear reducer in aviation, aerospace, energy, navigation, shipbuilding, bionic machinery, common ordnance, machine tools, instruments, electronic equipment, mining and metallurgy, transportation, lifting machinery, petrochemical machinery, textile machinery, agricultural machinery, etc. It is getting more and more widely used, especially in the servo system with high dynamic performance. The use of harmonic gear transmission shows its superiority. It delivers power from tens of watts to tens of kilowatts, but high-power harmonic gear drives are often used in short-term applications.

As long as the speed reducer is needed in the mechanism for transmitting power and motion, the application range of the helical gear reducer is quite extensive, and it can be seen in almost all kinds of mechanical transmission systems, from the ship of the vehicle, Automobiles, locomotives, heavy machinery for construction, processing equipment used in the machinery industry and automated production equipment.
