A disc lift shaft assembly for active steering

Abstract

The present invention relates to a disc lifting shaft assembly for active steering, comprising a shaft beam assembly, a disc wheel rim assembly, a kingpin, a steering knuckle arm, a steering tie rod arm and a tie rod assembly. Wherein, the shaft beam assembly comprises a shaft tube, a shaft head, an airbag support, a combination bracket, a thrust rod seat assembly, a hydraulic support, a stabilizer rod support and a pipe fixing bracket, wherein the shaft beam assembly comprises a shaft tube, a shaft head, an airbag support, a combination bracket, a thrust rod seat assembly, a hydraulic support, a stabilizer rod support and a pipe fixing bracket; The shaft head is provided with a kingpin hole and a limiting boss; The disc wheel rim assembly is respectively connected with the shaft head through a kingpin; The tie rod arm comprises a left tie rod arm and a right tie rod arm, which are respectively installed on the disc wheel edge assemblies on the left and right sides, are both positionedabove the steering knuckle arm, and are respectively connected with the two ends of the tie rod assembly. The invention solves the problems of inflexible steering and non-universalization of the structure in the prior art through the design of the structure, and has positive technical significance.

Description

technical field [0001] The invention relates to an active steering disc-type lifting shaft assembly, which belongs to the technical field of auto parts. Background technique [0002] In the field of heavy-duty trucks, customers have higher and higher requirements for the intelligence, comfort, safety, and energy efficiency of road transport vehicles. Matching air suspension, disc brakes, and disc brakes with standard electronic wear alarm devices will become road vehicles. mainstream configuration trends. [0003] Urban trucks are limited by space in many workplaces, and require flexible steering and a turning radius as small as possible; at present, the rear steering axles used in the domestic market are mostly follow-up steering axles, which cannot be used due to structural constraints. The actual turning needs to coordinate and match the corners of the front and rear steering axles. When the rear steering axle turns, it will cause the wheels to drag and slip, causing the...

AI Technical Summary

Problems solved by technology

[0003] Urban trucks are limited by space in many workplaces, and require flexible steering and a turning radius as small as possible; at present, most of the rear steering axles used in the domestic market are follow-up steering axles, which cannot be used due to structural constraints. The actual turning needs to coordinate and match the corners of the front and rear steering axles. When the rear steering axle turns, it will cause the wheels to drag and slip, and the problem of tire eating will occur.

[0004] At present, the common rear steering axle in the market has a single structure, and generally adopts a non-universal structure design. Different models need to develop different rear steering axles. The development cycle is long and the production cost is high.

[0005] In addition, most rear steering axles in China adopt a drum wheel rim structure. Excessive wear of the brake friction lining will cause brake failure and affect driving safety. The wear of the friction lining can only be checked in detail by disassembling the wheel rim, which reduces the Vehicle Operational Efficiency
