The transmission system typically consists of a clutch, transmission, universal transmission, final drive, differential, and half shaft.
Its primary function is to transfer power from the engine to the vehicle’s driving wheels, creating the driving force that allows the car to move at a specific speed.
It can be broadly categorized into two types:
① Frictional transmission, which transmits power and motion through friction between components, including belt drive, rope drive, and friction wheel drive.
② Engagement transmission, which transmits power or motion through the interaction of active and driven members, or a middle member, including gear transmission, chain transmission, screw transmission, and harmonic transmission.
Transmission mode classification
Mechanical transmission is classified based on the method of force transmission and can be further divided into:
- Friction drive
- Chain drive
- Gear transmission
- Belt drive
- Turbo vortex drive
- Ratchet drive
- Crankshaft connecting rod drive
- Pneumatic drive
- Hydraulic transmission (hydraulic planing)
- Universal joint drive
- Wire rope drive (most commonly used in elevators)
- Coupling drive
- Spline drive
Basic categories include: reducer, brake, clutch, coupling, variable speed changer, lead screw, and slide rail.
