automotive suspension spring

automotive suspension spring with leaf coil type optional

Automobile suspension spring is the elastic element in the suspension of the car, so that the axle and the frame or body of the elastic connection between the axle and the frame or body, to bear and transfer the vertical load, ease and inhibit the impact caused by the uneven road surface.

Description

Vehicle suspension refers to all force-transmitting connections between the frame or load-bearing body and the axle or wheels. The main function of the suspension is to transfer vertical, longitudinal, and lateral reaction forces, as well as the torque generated by these forces, to the frame or body, ensuring the normal operation and handling of the vehicle.

Common Types of Suspension Springs

  1. Steel Plate Springs: The most widely used elastic element in automobile suspension. Composed of several alloy spring plates of equal width but varying length and thickness, forming a beam with approximately equal strength and elasticity.
  2. Coil Springs: Commonly used in independent suspensions, especially front-wheel setups, and sometimes in rear-wheel non-independent suspensions. Coil springs offer advantages over leaf springs, such as no need for lubrication, resistance to dirt, compact longitudinal mounting, and low mass.
  3. Torsion Bar Springs: Spring steel torsion bars, with ends that can be round, rectangular, or tubular, and shaped for specific connections. One end is fixed to the frame, the other to the suspension arm connected to the wheel, allowing for torsional elasticity.
  4. Gas Springs: Sealed containers filled with compressed gas. Their stiffness is variable and adjusts according to the load, offering ideal variable stiffness characteristics for improved ride comfort and performance.
  5. Rubber Springs: Utilize the inherent elasticity of rubber to absorb compression and torsion loads. They offer higher energy storage per unit mass than metal springs, excellent acoustic properties, no noise, and require no lubrication.
