AI Technical Summary

Technical Problem

In existing cars, the transverse stabilization bar is difficult to disconnect under off-road conditions, resulting in insufficient suppression of backhop stroke, affecting off-road performance. At the same time, the electronically controlled fork-type system cannot be disconnected during off-road, and the fork-disconnector is prone to water inlet and rust, which has poor reliability.

Method used

By setting two piston components in the stabilizing rod assembly and switching the on-off state of the built-in flow channel in its built-in regulating valve, the disconnection or connection of the stabilizing rod is achieved, reducing the radial size of the stabilizing rod assembly, simplifying the external oil circuit, and improving system reliability.

Benefits of technology

Reduce roll when turning, reduce the roll, reduce the suppression of the rebound stroke of the stability bar on the left and right wheels of the suspension, improve off-road performance, and improve the reliability and layout flexibility of the system.

Abstract

The invention discloses a stabilizer bar assembly and a vehicle, the stabilizer bar assembly comprises a first stabilizer bar and a second stabilizer bar; a first cavity, an adjusting cavity and a second cavity are formed in the cylinder barrel; the first piston assembly is movably installed in the first cavity and divides the first cavity into two first sub-cavities, the first piston assembly is provided with a first adjusting valve, one of the two first sub-cavities is communicated with the adjusting cavity, and the other first sub-cavity is selectively communicated with the adjusting cavity through the first adjusting valve; the first piston assembly is connected with the first stabilizer bar; and the second piston assembly is movably installed in the second cavity and divides the second cavity into two second sub-cavities, the second piston assembly is provided with a second adjusting valve used for selectively communicating the two second sub-cavities, and the second piston assembly is connected with the second stabilizing rod. According to the stabilizer bar assembly, the radial size of the stabilizer bar assembly is reduced, meanwhile, an oil way is simplified, and the system reliability is improved.
