Abstract

The invention discloses a front wheel steering mechanism and belongs to the technical field of vehicle engineering. It includes motors, gears, gear rods, and folded pillars. The motor is used as the driving force to drive the gear, and the gear and the gear rod are meshed with each other, and then linked with the folding pillar to make the wheel turn. The invention has the advantages of simple structure and easy realization.

Description

Foresteerage gear

Technical field

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

Background technology

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

Summary of the invention

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

A kind of foresteerage gear is characterized in that: comprise the front-wheel pivot shaft, the front-wheel pivot shaft is fixedly mounted in the pivot shaft fixed muffle, and the pivot shaft fixed muffle is fixed on the front-wheel pivot shaft 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 the X bar is parallel with the front-wheel pivot shaft, and the Z bar is vertical with the X bar, and the Y bar is vertical with the X bar; Wherein first end of X bar links to each other with front-wheel by bearing, second end of X bar and first end of Z bar are connected, and second end of Z bar and first end of Y bar are connected, and second end of Y bar is equipped with the ratch fixed hinge, the hinge rotating shaft is installed in the ratch fixed hinge, and the hinge rotating shaft is perpendicular to the X bar; Two ends, the above-mentioned front-wheel pivot shaft left and right sides have tube-in-tube structure respectively, the axis of this tube-in-tube structure and front-wheel pivot shaft axis normal; The Z bar of described 2 folding shape pillars is installed in the tube-in-tube structure at two ends, the front-wheel pivot shaft left and right sides respectively by bearing; Also comprise the ratch by hinge rotating shaft installation, the gear with the ratch cooperation, the electrical motor that links to each other with gear.

The present invention uses motor to replace original mechanical trigger mechanism, motor is participated in directly and is turned to, from turning to trigger mechanism only just can meet the demands with lead to turning to the actuating unit, avoided the complex structure that uses mechanical mechanism to bring, in addition, can use turning to of automatic control control vehicle like this.Mechanism is simple, is easy to realize.

The specific embodiment

Below in conjunction with accompanying drawing and the specific embodiment the present invention is done explanation in further detail.

Fig. 1 is the scheme drawing of steering structure.Shown in the visual angle for overlooking.

As shown in Figure 2.Motor 1 driven gear 2 rotates, and gear 2 and ratch 3 engagements make circular movement be converted into cross motion.Under the link of ratch fixed hinge 12, ratch 3 drives folding shape pillar 7 and reverses.Folding shape pillar 7 reverses in direction perpendicular to the ground, and power is passed to wheel 8, and two wheels 8 are rotated simultaneously, reaches the purpose that turns to.
