Description
Technical field
The invention is related to a kind of Vehicular turn technical field, especially one kind and being mainly used for lawn machine etc. running at a low speed
Steering mechanism on vehicle.
Background technology
With the fast development of China's economy, appearance of city is maked rapid progress, and garden greenland and green coverage are continuously increased.For
Working efficiency is reduced labor intensity and improves, the slow moving vehicles such as lawn machine and agricultural tillage machine are widely used.
Mainly there are following three kinds of structures in the steering mechanism of the slow moving vehicles such as current lawn machine：One is steering columns to weld directly below
Deflecting plate is connect, front-wheel steer is pulled by pull rod by deflecting plate, is similar to the steering mechanism of all-terrain vehicle, advantage is structure
Simply, it turns to directly, the disadvantage is that turning to weight, it is poor to drive sense.Be for second be fixed with below steering column pinion gear and with a fluted disc
Engagement, fluted disc are connect by pull rod with certain front-wheel again, and fluted disc center has circular hole, built-in bushing, liner height to be slightly above fluted disc thickness
Degree, an end face of bushing lean against in a plane of rack, another end face is pushed down with clamping plate；Because having added gear drive, this
Kind mechanism is lighter than the steering of the first mechanism, the disadvantage is that cooperation required precision is high, gap is big, idle stroke is big, and system stiffness is low, drives
It is poor to multiply effect.The third is directly to use the steering mechanism of automobile and tractor, such as gear-rack steering mechanism, and structure is more multiple
Miscellaneous, cost is higher.For this purpose, many manufacturers and knowledgeable people have carried out R and D, but there has been no relatively rational so far
Method solves the above problems.
Invention content
In order to overcome above-mentioned disadvantage of the existing technology, the purpose of the invention is to provide a kind of simple in structure tight
It gathers, turn to flexible, light, the low slow moving vehicle steering mechanism of driving comfort, production cost of operation.

On right pin pipe, corresponding in the rack to be fixed with direction seat pipe and turn to seat pipe, steering column is installed in rotation on direction
In seat pipe, steering wheel is fixed on the top of steering column, and the lower part of steering column is fixed with tooth sector, turns to and passes through steering in seat pipe
Plate guide post is equipped with rotatable deflecting plate, and the top of deflecting plate is equipped with the adjustable fluted disc of front and back position, fluted disc and tooth sector
Engagement, pull rod has been correspondingly connected between the king pin of deflecting plate both sides and the steering connecting seat of left and right front-wheel.
The further scheme of the invention is equipped with regulating device, the regulating device between the deflecting plate and fluted disc
Positioning plate including downward bending on the screw hole being correspondingly arranged on deflecting plate and notch, fluted disc and across notch is set on screw hole
There is the adjusting screw of screw-thread fit, the end face of adjusting screw, which is withstood on positioning plate, makes fluted disc and tooth sector positive engagement.
The further scheme of the invention, the direction seat pipe and turn to seat pipe both ends be correspondingly provided with steering column and
The anti-friction bush of the dynamic cooperation of deflecting plate guide post.
The further scheme of the invention, the preceding bridge are connected to by front axle set in rack, and preceding bridge can be around preceding
Bridge axle set is swung.
The further scheme of the invention, the central axes of the deflecting plate guide post and the central axes of steering column are mutually parallel
Or mutually form angle less than 30 degree.
The further scheme of the invention, the both ends of the pull rod have been correspondingly connected with oscillating bearing.
With the above structure, it has the following advantages compared with the prior art and effect:First, deflecting plate is led by deflecting plate
Column, which is installed in rotation on, to be turned in seat pipe, and deflecting plate stable direction, fluted disc front and back position is adjustable to be fixed on deflecting plate simultaneously
It is engaged with tooth sector, stable drive, steering is flexibly light, and the gap with tooth sector, control biography can be adjusted by fluted disc
Dynamic gap is in optimum position.Second is that due to being equipped with regulating device between deflecting plate and fluted disc, it is fixed by rotating adjusting screw top pressure
Position plate, you can adjust the gap between fluted disc and tooth sector, it is ensured that fluted disc and tooth sector positive engagement.Third, with side
It can ensure to turn to flexibly light with reducing friction resistance to column and the anti-friction bush of the dynamic cooperation of deflecting plate guide post.
