Buick Regal Trailing Arm
About Trailing Arm
The trailing arm is a part of a vehicle's suspension system. It's the suspension piece that connects the axle of the vehicle to its chassis. In some cases the trailing arm itself will have trailing arm bushings, which is essentially a component of rubber or polyurethane that acts as a cushion to reduce the friction between the suspension parts. If your vehicle has a different type of suspension, such as; leaf spring, double wishbone or multi-link suspension, the trailing arm may not be present.
What is the purpose of Trailing Arm?
The principal role of the trailing arm is to locate and monitor the vehicle's rear axle movement. The trailing arms are kept fairly long to keep the wheels as straight as possible for vertical movement. That also ensures that there is no toe-in and toe-out problem. In the case of trailing arms with hard mounted differential and half shafts, the suspension is often composed of both an upper link arm and the lower primary link arm. This type of setup helps avoid the problem of changes to the toe. Besides, it often keeps the wheels upright during the suspension ride in order to prevent camber shifts. This is mostly used in trucks and 4X4 vehicles, because they can be strong and prevent damage to stress.
How Trailing Arm Works?
They introduced trailing arms to solve a problem. The problem was that many arms control and drive axles had limited longitudinal movement support which allows the wheel to move properly forward and backward in the wheel. The trailing arm is placed either before or behind the axle or the control arm, and it is fixed directly to the frame. The two ends of the trailing arm allow the suspension to move up and down easily, but since it is mounted perpendicular to the control arm / axle the wheel and hub can not move in any other direction, thus allowing a high degree of stability at the same time ensuring the suspension system's necessary motion. The trailing arms prevent the vehicle from travelling in the lane and ensure road safety
