Chang'an 474

This product is the Differential and Reduction Assembly for Chang'an 474, a core power transmission component produced by Hebei Hengsheng Auto Parts Co., Ltd. Its key details and functional characteristics are as follows:

Applicable Model

It is specifically designed for the Chang'an 474 (a light passenger/commercial vehicle), matching the vehicle’s rear axle system to support its urban commuting, passenger transport and light cargo hauling scenarios.

Core Parameters

Final Drive Gear Ratio: 11:43 (this ratio prioritizes torque output, adapting to the vehicle’s needs for carrying passengers or light loads in urban and suburban environments)

Half Shaft Gear Tooth Count: 25 (ensures precise meshing with associated components, enabling stable power distribution between left and right wheels during driving)

Functional Role

The final drive (corresponding to the "basin angle gear") reduces the engine’s output speed, amplifies torque, and adjusts the direction of power transmission to drive the wheels.

The differential (equipped with the 25-tooth half shaft gear) resolves the speed difference between left and right wheels when turning, maintaining smooth and stable vehicle handling.

Application Scenarios

As a key part of the Chang'an 474’s rear axle, it is suitable for urban logistics, short-distance passenger transport, and daily operational use, providing reliable power transmission and durable performance for the vehicle.
