The automotive spacer is an important component in the vehicle's drivetrain system, used to connect the engine and the transmission, transferring power from the engine to the vehicle's drive wheels. Here is a brief explanation of the principles and functions of a spacers.

Principles:
An automotive spacer typically consists of two or more interconnected metal annular discs. These discs are secured together using bolts, forming a structurally solid unit. One side of the discs connects to the output shaft of the engine, while the other side connects to the input shaft of the transmission. The power from the engine is transmitted through the spacers to the transmission, which then drives the vehicle's wheels.

Functions:

A--Power Transmission: The spacers transfers the rotational power from the engine to the transmission, enabling the vehicle to be driven. It transmits torque by connecting the shafts between the engine and the transmission, ensuring seamless power transfer.

Compensating for Axial Displacement: The spacers allows for axial displacement between the engine and the transmission. During vehicle operation, there may be relative movement between the engine and the transmission due to uneven road surfaces or suspension system dynamics. The spacers are designed to withstand this axial displacement, maintaining the connection in the drivetrain system, enabling it to function properly.

B--Vibration Absorption and Noise Reduction: In addition to power transmission, the spacers are capable of absorbing vibrations and reducing the impact forces generated in the drivetrain system, thereby minimizing their impact on other components. This helps to reduce noise and provide a smoother driving experience.

In summary, the main functions of an automotive spacers include power transmission, compensating for axial displacement, and absorbing vibrations to reduce noise. It ensures effective transfer of engine power to the vehicle's drive wheels while protecting other components in the drivetrain system.
