The gearbox is the basic component of the transmission. All parts in the transmission are directly or indirectly installed and fixed on the transmission case. There are bearing housing holes on the transmission case for installing the input shaft assembly and the output shaft assembly. If the bearing housing holes are worn, the stability of the rotating shaft and the gear ratio will be damaged, resulting in shift stagnation and shift noise Increase, deterioration of gearbox seal, lubricating oil leakage, etc. The quality of the gearbox determines the working performance and service life of the gearbox assembly. The main function of the gearbox is to support the drive shaft, ensure the center distance and parallelity between the shafts, and ensure the correct installation of the gearbox components and the engine.

The role of 1. gearbox

1. According to the needs of road conditions and driving conditions, change the driving speed of the vehicle to provide appropriate driving force.

2. Cut off or transfer the engine power as needed, so that the engine can effectively output power or idle speed.

Therefore, the processing quality of automobile gearbox parts not only directly affects the assembly accuracy and motion accuracy of automobile gearboxes, but also affects the working accuracy, performance and life of automobiles.

Maintenance of 2. gearbox

1. Regular inspection and replacement of transmission oil

When the vehicle is used for a long time, the oil temperature of the gearbox is very high. Under high temperature conditions, the oil will be oxidized and deteriorated, the viscosity of the oil will become thinner, and the lubrication and heat dissipation capabilities will decrease. In severe cases, the gearbox will wear and burn, and will not be replaced for a long time. The deterioration of the engine oil will produce sludge, wear impurities will be mixed with the engine oil, and the engine oil will circulate in the gearbox system to accelerate the damage of the gearbox components.

2. Replace the transmission oil correctly

The manual static oil drain method cannot drain the oil clean. The new oil replaced is actually a mixture of new and old oil. The sludge and impurities produced by the long-term use of the transmission cannot be discharged, which will cause wear and damage to the internal parts of the transmission. The dynamic oil change with intelligent switch can filter and circulate the impurities in the automatic transmission system; let the gearbox have a good internal working environment and extend the service life of the gearbox.

The automobile gearbox is mainly used to change the speed of the car and change the speed of the car. The top surface of the automobile gearbox box part is used to install the gearbox cover, and the support holes mm120 and mm80 on the front and rear end surfaces are used to install the drive shaft to realize its speed change function. The main processing surface of the gearbox parts is plane and hole system. In general, ensuring the dimensional accuracy of the hole system is more difficult than ensuring the dimensional accuracy of the plane. Therefore, for the reverse design of the gearbox housing, it is mainly to ensure the dimensional accuracy and position accuracy of the hole, and to deal with the relationship between the hole and the plane.
