Abstract

The invention discloses a kind of foresteerage gear, belong to Vehicle Engineering technical field.It comprises motor, gear, ratch, folding shape pillar.With motor as prime power driven wheel, gear and ratch engage each other, then link wheel is turned to folding shape pillar.It is simple that the present invention has structure, is easy to realize.

Description

Foresteerage gear

Technical field

The present invention relates to a kind of foresteerage gear, belong to Vehicle Engineering technical field.

Background technology

Existing steering structure major part is all that single wheel braking turns to or manual steering or hydraulic braking, and turning efficiency is undesirable, and location is inaccurate.Structure bulky and complicated.

Summary of the invention

The technical problem to be solved in the present invention is to provide that a kind of volume is little, structure is simple, accurate positioning, the steering hardware that easily realizes.

A kind of foresteerage gear, it is characterized in that: comprise front wheel supporting axle, front wheel supporting axle is fixedly mounted in pivot shaft fixed muffle, and pivot shaft fixed muffle is fixed on front wheel supporting axle anchor post, and anchor post and vehicle body are fixed;

; Also comprise 2 folding shape pillars, each folding shape pillar is made up of Y bar, Z bar, X bar, and wherein X bar is parallel with front wheel supporting axle, and Z bar is vertical with X bar, and Y bar is vertical with X bar; Wherein the first end of X bar is connected with front-wheel by bearing, second end of X bar and the first end of Z bar are connected, and the second end of Z bar and the first end of Y bar are connected, and the second end of Y bar is provided with ratch fixed hinge, be provided with hinge rotating shaft in ratch fixed hinge, hinge rotating shaft is perpendicular to X bar; Two ends, above-mentioned front wheel supporting axle left and right have tube-in-tube structure respectively, the axis of this tube-in-tube structure and front wheel supporting axle axes normal; The Z bar of described 2 folding shape pillars is installed on respectively by bearing in the tube-in-tube structure at two ends, front wheel supporting axle left and right; Also comprise the ratch installed by hinge rotating shaft, the gear coordinated with ratch, the electrical motor that is connected with gear.

The present invention uses motor to replace original mechanical trigger mechanism, motor is participated in directly and is turned to, only just can meet the demands with wire from turning to trigger mechanism to turning to actuating unit, avoid the complex structure using mechanical mechanism to bring, in addition, control automatically can be used like this to control turning to of vehicle.Mechanism is simple, is easy to realize.

Detailed description of the invention

Below in conjunction with accompanying drawing and detailed description of the invention, the present invention is described in more detail.

Fig. 1 is the schematic diagram of steering structure.Shown visual angle is for overlooking.

As shown in Figure 2.Motor 1 driven gear 2 rotates, and gear 2 engages with ratch 3, makes circular movement be converted into cross motion.Under the link of ratch fixed hinge 12, ratch 3 drives folding shape pillar 7 to reverse.Folding shape pillar 7 reverses on direction perpendicular to the ground, power is passed to wheel 8, two wheels 8 is rotated simultaneously, reaches the object turned to.
