Torsion bar suspension realizing circumferential rotation adjustment and self-locking by worm and gear

Abstract

The invention relates to a torsion bar suspension realizing circumferential rotation adjustment and self-locking by a worm and a wheel, wherein, one end of a torque tube is connected with a worm wheel of a worm-and-wheel drive part, while the other end of the torque tube is connected with a shell of a coaxial rotary oscillating damper; a torsion lever is arranged in the torque tube; one end of the torque tube is connected with the worm wheel of the worm-and-wheel drive part, while the other end of the torsion lever is connected with a balance arm; a limit disc is fixed on the balance arm; thelimit disc is connected with a rotating shaft of the coaxial rotary oscillating damper; a plurality of heaves are circumferentially and evenly distributed on the limit disc; a plurality of limitatorscorresponding to the heaves are circumferentially and evenly distributed on the shell of the coaxial rotary oscillating damper; and the outside of the balance arm is connected with an end cover of the balance arm. The invention can realize circumferential rotating adjustment of a torsion bar suspension system to ensure the torsion bar suspension realizes rotation in a certain angle, even in 360 degrees and above, and dead locking at an arbitrary position, thereby meeting the requirement of normal running and vehicle crossing over a barrier.

Description

technical field [0001] The invention relates to a suspension of a vehicle, in particular to a torsion bar suspension which uses a worm gear to realize circumferential rotation adjustment and self-locking. Background technique [0002] The torsion bar suspension system is widely used in various vehicles. In order to further improve the driving performance of the vehicle, the torsion bar suspension needs to be adjusted to achieve different vehicle body heights from the ground. However, the existing torsion bar suspension The system cannot realize the adjustment of the height of the vehicle body from the ground. [0003] In order to realize the height of the car body from the ground and the adjustment of the car posture, the oil-pneumatic suspension system is often used, and the driving posture and the height of the car body from the ground are changed by charging and discharging oil to the oil-pneumatic spring. However, using the characteristics of oil-pneumatic springs that ...

AI Technical Summary

Problems solved by technology

However, using the characteristics of oil-pneumatic springs that can be filled and discharged to adjust the vehicle height has the following disadvantages: first, the cost of the oil-pneumatic suspension system is high, and maintenance is complicated; Therefore, the adjustment range of the height of the vehicle body from the ground is limited

However, this patent does not have a mechanism based on the torsion bar adjustment of the electric wheel, so the circumferential rotation adjustment of the suspension cannot be realized
