The trailing arm type independent suspension means in the longitudinal plane of the wheel swing car suspension structure, divided into single and double vertical arm vertical arm in two forms. Single-longitudinal-arm suspension angle will have a greater change in the kingpin when the wheel up and down, single-longitudinal-arm suspension having a horizontal and vertical small occupied space, does not change with wheel track runout, simple structure, low cost advantages, mainly used in the suspension.
1. Introduction single longitudinal-arm suspension
The trailing arm type independent suspension means in the longitudinal plane of the wheel swing car suspension structure, divided into single and double vertical arm vertical arm two forms. Single-longitudinal-arm suspension angle will have a greater change in the kingpin when the wheel up and down, single-longitudinal-arm suspension having a horizontal and vertical small occupied space, does not change with wheel track runout, simple structure, low cost advantages, mainly used in the suspension. Double trailing arm suspension generally made of two swing arms of equal length, forming a parallel four-bar linkage, so that, after the up and down when the wheel angle kingpin remains unchanged. Double trailing arm suspension on a multi-application in the steering wheel.
2 single trailing arm suspension structure
single longitudinal sides of the wheel independent suspension arm to the vehicle body do not independently resilient connection, but through the rear axle assembly is connected. The elastic pad connected to the wheel with the elastic body, two single trailing arm connected with the torsion bar spring rear axle assembly by the elasticity of about. Single vertical arm independent suspension when the wheel moves up and down caster angle will have a greater change in the current with little chance of the front suspension, the suspension is mainly used.
