Whole automobile attitude adjusting mechanism based on stepless adjusting and automobile chassis

Abstract

The invention discloses a whole automobile attitude adjusting mechanism based on stepless adjusting. The adjusting mechanism comprises a torsion bar spring, wherein the torsion bar spring is arranged under an automobile frame, the front end of the torsion bar spring is connected with a swing arm mechanism which is connected with automobile wheels, the back end of the torsion bar spring is connected with the automobile frame through a torsion bar mounting frame, the torsion bar mounting frame is provided with a driving mechanism, the driving mechanism is used for driving the torsion bar spring to do initial torsion, the torsion bar spring transfers the torque generated by the driving mechanism to the swing arm mechanism, the downward action force generated by the free end of the swing arm mechanism is transferred to the ground through the automobile wheels, and the reaction force generated by the ground is received and reversely transferred to the automobile frame, so as to adjust the height of the automobile frame. An automobile chassis comprises the automobile frame, the automobile wheels, a suspension system and the whole automobile attitude adjusting mechanism, wherein the whole automobile attitude adjusting mechanism is connected with the automobile wheels through the suspension system. The whole automobile attitude adjusting mechanism has the advantages that the calibrating qualified rate of the whole automobile is effectively increased, the manufacturing precision of relevant component parts of the independent suspension is reduced, and the cost is also reduced.

Description

technical field [0001] The invention relates to a whole vehicle attitude adjustment mechanism and a chassis, in particular to a whole vehicle attitude adjustment mechanism and a chassis based on stepless adjustment. Background technique [0002] With the development of the expressway network, the driving speed of automobiles continues to increase, and people pay more attention to the driving stability and driving safety of vehicles at higher driving speeds, which makes the use of independent suspensions on vehicles a development trend. [0003] For the general layout of the chassis of the independent suspension and the design of the whole vehicle, how to control the attitude angle of the whole vehicle within a certain range and enhance its adaptability has always been an important issue, and the adjustment of the attitude of the whole vehicle is also an important content of chassis tuning. The dive angle of the whole vehicle must be controlled within a precise range for mass...

AI Technical Summary

Problems solved by technology

The only way to ensure that the whole vehicle meets the design and inspection requirements and has consistency is by improving the machining accuracy of parts. This method cannot fundamentally solve the problem, and strictly improving the machining accuracy of parts will cause a substantial increase in production costs. , which is not conducive to reducing costs and improving the competitiveness of the vehicle, and is not conducive to later after-sales maintenance
