Truck gearbox assembly Introduction of gearbox HW19710

Internal structure and working principle

Gear system: It contains multiple gears of different sizes. Different gears are achieved by meshing combinations of different gears. These gears are usually made of high-strength alloy steel to ensure that they can withstand high-load operation. During the shifting process, the gears or synchronizers and other components are moved by the shift fork to make different gear sets enter the meshing state, thereby changing the transmission ratio.
Synchronizer: It is equipped with a synchronizer device. Its main function is to quickly synchronize the speed of the gears to be meshed during the shifting, so as to achieve smooth shifting. The synchronizer can reduce the impact between gears, extend the service life of the gearbox, and make the driver more relaxed and comfortable when shifting.
Lubrication system: It has a complete lubrication system to ensure that all moving parts inside the gearbox can be well lubricated. Generally, the lubricating oil is delivered to each part that needs lubrication, such as gears, bearings, etc. through an oil pump. The lubricating oil can not only reduce the friction between the parts, but also play a role in heat dissipation to prevent the gearbox from being damaged due to overheating.
