Adjusting Mechanism of Caster Angle of Single Trailing Arm Independent Suspension

Abstract

The invention belongs to the technical field of single trailing arm suspension, and in particular relates to an adjustment mechanism for caster angle of a single trailing arm independent suspension kingpin, comprising a single trailing arm, a drive motor assembly, an encoder for swing angle of a single trailing arm, and a steering knuckle And steering knuckle transition bracket, etc. The motor casing of the drive motor assembly is fixedly connected with the single trailing arm, and its motor output shaft is fixedly connected with the steering knuckle transition bracket. According to the swing angle of the single trailing arm relative to the frame, the motor output shaft of the drive motor assembly drives the steering knuckle transition bracket , Steering knuckle, and wheel hub motor casings rotate together at a certain angle to ensure that the steering wheels have different caster angles under various working conditions. The mechanism adopted in the present invention can adjust the caster angle of the steering wheel of the single trailing arm independent suspension accurately, independently and in real time, and has a high degree of integration, which solves the problem that the caster angle of the single trailing arm independent suspension has a relatively large change and The disadvantage that the initial value can only be determined at design time has important reference significance for the application and development of single trailing arm independent suspension.

Description

technical field [0001] The invention belongs to the technical field of single trailing arm suspension, and in particular relates to an adjustment mechanism for a kingpin caster angle of a single trailing arm independent suspension. Background technique [0002] For the single trailing arm independent suspension of a traditional vehicle, the kingpin caster angle is determined during the overall design. Once the initial design value of the kingpin caster angle corresponding to the vehicle’s full-load static equilibrium position is determined, it needs to passively satisfy the various requirements of the entire suspension. The use of working conditions. However, the requirements of the steering wheel of the front axle and the steering wheel of the rear axle on the caster angle of the kingpin, the requirements of the caster angle of the flat road and different undulating roads, the requirements of the caster angle of the different speeds on the caster angle, and the requirements...

AI Technical Summary

Problems solved by technology

When the kingpin caster angle does not meet the requirements, it will cause wheel shimmy, and may also cause vibration and noise. It cannot provide a suitable steering return torque, which affects the straight-line driving stability and steering stability of the vehicle, and cannot meet the vehicle's handling stability. needs
