C7 series spindle

The concept of commercial vehicles is mainly defined from its own different uses, and it is customary to divide commercial vehicles into two categories: passenger cars and trucks. The actual use of the car is very complex, such as starting, idle parking, low speed, etc., which requires the driving force and speed of the car to change within a considerable range, and the output torque and speed change range of the piston engine that is widely used at present is small. In order to adapt to the frequently changing driving conditions and at the same time to make the engine work under favorable operating conditions (higher power, lower fuel consumption), a transmission was set up in the drivetrain. Transmission is one of the main components of the automotive transmission system, is used to change the speed and torque from the engine mechanism, it can fix or divide the gear to change the output shaft and input shaft transmission ratio, also known as the gearbox.

It is a device that changes the speed of a car and consists of many gears of different diameters and sizes. The gearbox is mainly used to change the torque and speed of the engine crankshaft to meet the needs of the car in different driving conditions such as starting, accelerating, driving and overcoming various road obstacles.

Transmission gears rely on their own structural dimensions and material strength to withstand external loads, which requires materials with high strength toughness and wear resistance; Due to the complex shape of the gear, the precision of the gear is high, and the material is also required to be good in craftsmanship.

Our company can realize the processing of drawing or sample, from raw materials to the development and processing of finished products, and the development cycle can be as low as 15 days. The blank is finely forged to meet the strength and low utilization rate of small materials with small margins, reducing costs.
