Description
Technical field
The utility model relates to a kind of chassis design manufacturing technology field of engineering truck, especially a kind of vehicle chassis four
Take turns linkage steering apparatus.
Background technique
It is very big for the demand of various engineering trucks both at home and abroad at present, before the steering system of many engineering vehicle chassis needs
Four-wheel steering afterwards, existing engineering truck is all less desirable in four-wheel steering system design aspect, when showing four-wheel steering
Corner it is inconsistent and the speed of travel is slow, front and back tire hinders engineering truck not in same track when travel speed is fast
Development.
Summary of the invention
Above-mentioned in order to overcome the shortcomings of, the utility model provides a kind of vehicle chassis four-wheel linkage steering apparatus, main to wrap
Include frame；Linkage pull rod；Corner connecting lever；Wheel；Swing Arm；Steering linkage；Umbrella tooth case；Link rack gear；Linkage gear；Transmission
Axis；Turn to vehicle bridge；Control arm；Hydraulic cylinder, it is characterised in that: turn to vehicle bridge and connected with frame, the both ends for turning to vehicle bridge can be real
Show the steering of wheel and be equipped with wheel and corner connecting lever, corner connecting lever and wheel rotate synchronously；One end of Swing Arm and turn
Being fixedly connected to one end of vehicle bridge rotates synchronously itself and wheel, and the other end of Swing Arm is connected with steering linkage pivot pin, links
Pull rod both ends are connected with corner connecting lever pivot pin；Umbrella tooth case is fixed on frame, is equipped with vertical umbrella tooth and transverse direction inside umbrella tooth case
Umbrella tooth, the tooth above tooth and lateral umbrella tooth above vertical umbrella tooth are permanently engaged mutually, the other end of vertical umbrella tooth and control
Arm is fixedly connected, and the both ends of transmission shaft are fixedly connected with lateral umbrella tooth and fixing assembling has linkage gear；One end of hydraulic cylinder
It is fixed on the other end on frame to connect with linkage rack gear, the tooth above tooth and linkage gear above the rack gear that links permanently is stung mutually
It closes；The vehicle chassis four-wheel linkage steering apparatus is just constituted by above-mentioned structure, hydraulic cylinder is past when the vehicle is turning
Multiple stretch drives linkage rack gear, and linkage rack gear just drives linkage gear to rotate, and linkage gear rotation is with regard to driving drive rod, lateral umbrella
Tooth, the rotation of vertical umbrella tooth, vertical umbrella tooth just drive control arm swing to make steering linkage stretch back and forth, and steering linkage is stretched back and forth
Contracting waves arm swing with regard to driving, and the swing of Swing Arm has just driven the same of four corner connecting levers and four wheels by linkage pull rod
Step is swung, and is so far achieved that the unidirectional synchronous steering of four wheels；Because of transmission shaft, lateral umbrella tooth, vertical umbrella tooth, control
Arm processed, steering linkage, Swing Arm, corner connecting lever realize synchronous interaction, so the vehicle chassis four-wheel linked steering fills
Set, make four wheels of engineering truck turn to when be always it is synchronous, in engineering truck straight line fast running, front and back wheel
Remain same track, the appearance of the vehicle chassis four-wheel linkage steering apparatus has promoted engineering truck preferably to send out
Exhibition.
It is connected the technical scheme adopted by the utility model to solve the technical problem is as follows: turning to vehicle bridge with frame, bogie car
The both ends of bridge can be realized the steering of wheel and be equipped with wheel and corner connecting lever, and corner connecting lever and wheel rotate synchronously；It shakes
One end of swing arm is fixedly connected with the one end for turning to vehicle bridge rotates synchronously itself and wheel, the other end and steering linkage of Swing Arm
Pivot pin connection, linkage pull rod both ends are connected with corner connecting lever pivot pin；Umbrella tooth case is fixed on frame, is equipped with inside umbrella tooth case perpendicular
To umbrella tooth and lateral umbrella tooth, the tooth above tooth and lateral umbrella tooth above vertical umbrella tooth is permanently engaged mutually, vertical umbrella tooth
The other end is fixedly connected with control arm, and the both ends of transmission shaft are fixedly connected with lateral umbrella tooth and fixing assembling has linkage gear；
One end of hydraulic cylinder is fixed on the other end on frame and connects with linkage rack gear, above the tooth and linkage gear above the rack gear that links
Tooth is permanently engaged mutually；The vehicle chassis four-wheel linkage steering apparatus is just constituted by above-mentioned structure, is turned in vehicle
To when hydraulic cylinder reciprocal telescopic drive linkage rack gear, linkage rack gear just linkage gear is driven to rotate, linkage gear rotation just drive
Drive rod, lateral umbrella tooth, the rotation of vertical umbrella tooth, vertical umbrella tooth just drive control arm swing to make steering linkage stretch back and forth,
Steering linkage is stretched back and forth waves arm swing with regard to driving, and the swing of Swing Arm just passes through linkage pull rod and driven four corner connecting levers
With the synchronous hunting of four wheels, it is so far achieved that the unidirectional synchronous steering of four wheels.
The utility model has the beneficial effects that transmission shaft, lateral umbrella tooth, vertical umbrella tooth, control arm, steering linkage, waving
Arm, corner connecting lever realize synchronous interaction, make the vehicle chassis four-wheel linkage steering apparatus, can make the four of engineering truck
A wheel turn to when be always it is synchronous, in engineering truck straight line fast running, front and back wheel also remains same track,
The appearance of the vehicle chassis four-wheel linkage steering apparatus, has promoted engineering truck preferably to develop, structure is simple.
