Dual-front axle vehicle steering system

Abstract

The invention relates to a dual-front axle vehicle steering system comprising a steering gear, a plumbing arm, a first front axle drag link, a transition pull bar, a power-assisted cylinder assembly, a second front axle drag link, a first front axle and a second front axle; the steering gear is arranged on a frame vertical beam through a steering gear rack; the top of the plumbing arm is connected with the steering gear, and the bottom of the plumbing arm is movably connected with the front end of the transition pull bar; the rear end of the transition pull bar is movably connected with the power-assisted cylinder assembly; the front end of the first front axle drag link is movably connected with the power-assisted cylinder assembly, and the rear end is movably connected with the first front axle; the front end of the second front axle drag link is movably connected with the power-assisted cylinder assembly, and the rear is movably connected with the second front axle. The power-assisted cylinder assembly can provide steering assist power, can serve as the transition rocking arm, needs no piston, and can bear more pressure, thus outputting bigger steering moment; the dual-front axle vehicle steering system is long in service life, and good in reliability.

Description

technical field [0001] The invention belongs to the technical field of automobile steering systems, in particular to a double front axle automobile steering system. Background technique [0002] A car with double front axle steering refers to a car with two steering axles.
