The chassis is the support of construction machinery, which can make the overall unit run in the specified direction at the speed and traction required for operation.
According to the characteristics of the traveling system, there are 2 main types of construction machinery chassis:
2. Tracked chassis, including transmission system, steering system(incl. braking), traveling system, rotary support device(load carrying)
Transmission System of Construction Machinery Chassis
The transmission components between the power unit and the driving wheel of construction machinery are collectively referred to as the transmission system.
The transmission system is divided into mechanical transmission, hydraulic mechanical transmission, hydraulic transmission and electric transmission.
The three main components of transmission system: Gearbox, Differential, Wheel Drive.
