The core function of the Sinotruk wedge support assembly (WG9100590031) is to act as an "elastic connection hub" between the engine and the chassis. While providing stable load-bearing capacity, it also protects the chassis and improves driving comfort by absorbing vibrations and buffering impacts.

Features

Main Performance and Functions

1.Load Support: Supports the static weight of the rear of the engine and its accessories.

2.Shock Absorption and Noise Reduction: The internal rubber layer effectively absorbs vibrations generated during engine operation, preventing direct transmission of vibrations to the frame and improving cab comfort.

3.Displacement Compensation: Allows for slight elastic displacement of the engine during vehicle start-up, braking, or on bumpy roads, protecting the transmission system (such as the clutch and gearbox connections).
