AI Technical Summary

Technical Problem

Existing stabilization bar systems are insufficiently stiff when turning or passing through pits, making it difficult to provide sufficient roll stability and safety.

Method used

By designing a stabilizing rod system, the working cross-section size of the first sleeve and the second sleeve can be variable, the cross-section is large when the connection is in the first state and the cross-section is small when the second state, the cross-section is small, and the cross-section is changed by using the connecting assembly and the limiting member to adjust the stiffness of the stabilizing rod.

Benefits of technology

It improves the stiffness of the stability bar system, enhances the roll stability and safety of the vehicle when turning or passing through pits, and reduces cross-sectional contact when driving in a straight line, improving driving comfort.

Abstract

The utility model provides a stabilizer bar system, a vehicle driving system and a vehicle. The stabilizer bar system comprises a first sleeve and a second sleeve which are connected with each other. When the stabilizer bar system is in a first state, the interface size of the joint of the first sleeve and the second sleeve is a first section size; when the stabilizer bar system is in a second state, the interface size of the joint of the first sleeve and the second sleeve is a second section size; the first cross-sectional dimension is greater than the second cross-sectional dimension. The connecting rigidity of the first sleeve and the second sleeve is changed by changing the sizes of the acting sections of the first sleeve and the second sleeve, the acting section in the first state is larger than the acting section in the second state, the acting sections of the first sleeve and the second sleeve in the first state are large, the rigidity of the stabilizer bar system is improved, and the service life of the stabilizer bar system is prolonged. And the driver can drive more safely.
