Vehicle and its steering system

Abstract

The invention discloses a carrier and a steering system thereof. The steering system of the carrier comprises a steering piece, a steering shaft, a universal joint, an input shaft, a left push rod and a right push rod, wherein the left push rod and the right push rod are arranged side by side in the transverse direction of the carrier. One end of the steering shaft is coaxially and fixedly connected with the steering piece. The upper end of the input shaft and the other end of the steering shaft are rotationally connected through the universal joint. The lower end of the input shaft is connected with the left push rod or the right push rod through an engagement transmission structure. The right end of the left push rod and the left end of the right push rod are connected through a middle piece. The middle piece can be fixedly connected with both the left push rod and the right push rod and can drive the left push rod and the right push rod to relatively get close to each other or away from each other. The invention further discloses the carrier. By the structural design of the carrier and the steering system of the carrier, transverse travel and in-place turning functions of the carrier can be achieved.

Description

technical field [0001] The present invention relates to the technical field of vehicles, and more specifically, relates to a vehicle and its steering system. Background technique [0002] Vehicles, such as vehicles, vans, etc., have become increasingly widespread. The steering system is one of the important components in the vehicle structure. Such as figure 1 As shown, a general vehicle steering system includes a steering member 01, a steering shaft 03 fixedly connected to the steering member 01, a rack and pinion steering device 06 connected to the steering shaft 03, and two ends of the rack and pinion steering device 06 respectively connected The left output shaft 05 and the right output shaft 07, wherein the reduction mechanism 04 can also be set between the steering shaft 03 and the rack and pinion steering gear 06, and the torque sensor 02 can be set on the steering shaft 03. When turning, turn the steering member 01, and then drive the steering shaft 03 to rotate, ...

Problems solved by technology

[0003] However, the steering system in the prior art can only realize the small-angle rotation of the left and right front wheels in the same direction, that is, the left front wheel and the right front wheel of the vehicle can only rotate to the left or right at a small angle at the same time, which cannot Realize the vehicle's lateral driving and in-situ turning functions, so that the steering mode of the vehicle is limited
