Description
Technical field
This utility model relates to automotive field, particularly relates to the omnidirectional mechanism of a kind of wheel steering system.
Background technology
Along with growth in the living standard, automobile has been increasingly becoming the main traffic instrument of people's trip.Automotive steering structure
Function be according to driver wish control automobile travel direction.Existing automotive steering structure, its Drag link and knuckle
Arm many employings ball pin structure connects, this kind of structure, and its angle range be ± 18 °, for road conditions more badly in the case of, car
Taking turns amplitude of beating relatively big, this kind of structure cannot meet use demand, thus, is badly in need of solving.
Utility model content
The purpose of this utility model is for the problems referred to above, it is provided that the omnidirectional mechanism of a kind of wheel steering system, to solve
Certainly existing vehicle steering mechanism angle range is little, and under the most severe road conditions, wheel hop amplitude is big, it is impossible to meets and uses need
The problem asked.
The purpose of this utility model is to be achieved through the following technical solutions:
The omnidirectional mechanism of a kind of wheel steering system, including steering arm, Drag link, knuckle arm and connects with steering wheel transmission
The steering gear connect, the outfan of described steering gear is in transmission connection with one end of steering arm, the other end of described steering arm and vertical pulling
One end of bar is rotationally connected, and the other end of described Drag link is in transmission connection with knuckle arm by universal joint, described universal joint bag
Including bearing, described bearing is fixing with Drag link to be connected, and bearing is rotatably connected to rotary shaft by bearing pin, and described knuckle arm is pacified
Being loaded in rotary shaft, the two ends that described rotary shaft is positioned at knuckle arm have been provided with the first boss of position-limiting action, second convex
Platform, is provided with between described knuckle arm and the first boss between gap, and knuckle arm and the second boss and is provided with gap.
As a kind of preferred version of the present utility model, described first boss is structure as a whole with rotary shaft.
As a kind of preferred version of the present utility model, described second boss is fixed on rotation by round nut, stop washer
In rotating shaft.
As a kind of preferred version of the present utility model, the outfan of described steering gear is by one end of spline with steering arm
It is in transmission connection.
The beneficial effects of the utility model are, the omnidirectional mechanism of described a kind of wheel steering system is by using universal joint real
Existing Drag link is in transmission connection with knuckle arm, it is ensured that wheel non-angular in significantly hopping process limits, and meets vehicle
The demand used under bad working environments, simple in construction, is easily achieved.

Detailed description of the invention
Further illustrate the technical solution of the utility model below in conjunction with the accompanying drawings and by detailed description of the invention.Can manage
Solving, embodiment described herein is used only for explaining this utility model, rather than to restriction of the present utility model.
Refer to shown in Fig. 1 to Fig. 3, Fig. 1 is the front view of the omnidirectional mechanism of a kind of wheel steering system of this utility model；
Fig. 2 is the top view of the omnidirectional mechanism of a kind of wheel steering system of this utility model；Fig. 3 is the structure of this utility model universal joint
Schematic diagram.
In the present embodiment, the omnidirectional mechanism of a kind of wheel steering system, including steering arm 2, Drag link 3, knuckle arm 4
And the steering gear 1 being in transmission connection with steering wheel, the outfan of described steering gear 1 is by the upper end transmission of spline and steering arm 2 even
Connecing, the lower end of described steering arm 2 is rotationally connected with the left end of Drag link 3, and the right-hand member of described Drag link 3 passes through universal joint and turns to
Joint arm 4 is in transmission connection, and described universal joint includes bearing 5, and described bearing 5 is fixing with Drag link 3 to be connected, and bearing 5 is by bearing pin 6
Being rotatably connected to rotary shaft 7, described knuckle arm 4 is installed in rotary shaft 7, and described rotary shaft 7 is positioned at the two of knuckle arm 4
End has been provided with first boss the 8, second boss 9 of position-limiting action, and described first boss 8 is structure as a whole with rotary shaft 7, described
Second boss 9 is fixed in rotary shaft 7, between described knuckle arm 4 and the first boss 8 by round nut 10, stop washer 11
It is provided with between gap, and knuckle arm 4 and the second boss 9 and is provided with gap.
During wheel hop, universal by be made up of rotary shaft 7, bearing 5, bearing pin 6 between knuckle arm 4 and Drag link 3
Joint structural transition, it is ensured that do not have the phenomenon that angle is inadequate and stuck during wheel hop；When hopping process turns to, rotation
First boss the 8, second boss 9 in rotating shaft 7 all and is reserved with gap between knuckle arm 4, is effectively guaranteed turn to suitable
Profit.
Above example simply elaborates ultimate principle of the present utility model and characteristic, and this utility model is not by above-mentioned enforcement
Example limits, and on the premise of without departing from this utility model spirit and scope, this utility model also has various change and change, these
In the range of change and change both fall within claimed this utility model.This utility model claims scope by appended right
Claim defines.
