The device can steer, lock or unlock wheels on demand.
Description
Technical field
The utility model relates to a kind of vehicle axle motoring condition control setup.
Background technology
Vehicle ' high speed and four-wheel steering high maneuverability are heavy off-road vehicle contradiction anxious to be solved.During heavy off-road vehicle low speed driving that no back axle turns to, maneuverability is poor, because of turn radius causes wear on tyres serious greatly.And all-wheel steered heavy off-road vehicle poor stability when running at high speed, trailing wheel easily produces phenomenons such as whipping.For solving its contradiction, when needing back axle to run at high speed as non-steering axle and during low speed driving as steeraxle, turn to the locking shifter just to become the task of top priority so research and develop a kind of vehicle rear axle.
Summary of the invention
The purpose of this utility model is to provide a kind of vehicle bridge to turn to the locking shifter.This device may command vehicle when running at high speed with the trailing wheel locking; When the needs tight turn radius, the trailing wheel locking is removed, realized rear-axle steering.
The technical solution adopted in the utility model is for achieving the above object: a kind of vehicle bridge turns to the locking shifter, between two wheels, be symmetrically arranged with the locking tie rod arm, the locking transition arm, locking push-off pin and push-off pin sleeve, one end of locking tie rod arm is connected with the vehicle bridge steering swivel, the other end is connected with an end of locking transition arm, the other end of locking transition arm is connected with an end of locking push-off pin, the locking push-off pin is positioned at the push-off pin sleeve and can moves along the push-off pin sleeve, between two push-off pin sleeves, be provided with " V " shape pull bar, the opening angle scalable of " V " shape pull bar, the top of " V " shape pull bar is connected with the piston rod of spacing lockup piston, two open ends of " V " shape pull bar are connected with the expansion link of corresponding side respectively, and expansion link is positioned at the push-off pin sleeve and can moves along sleeve.
Above-mentioned locking tie rod arm and locking transition arm are hinged, and locking transition arm and locking push-off pin are hinged.
Two open ends and the expansion link of above-mentioned " V " shape pull bar are hinged.
When the piston rod of above-mentioned spacing lockup piston was reduced to ultimate limit state, the opening angle of " V " shape pull bar became 180 °, and expansion link stretches in the push-off pin sleeve and contacts with the locking push-off pin.
Above-mentioned push-off pin sleeve is fixed on the vehicle bridge.
Above-mentioned spacing lockup piston is fixed on the vehicle bridge by support.
The beneficial effects of the utility model are: can realize that vehicle bridge turns to the function of locking by controlling stretching of spacing lockup piston piston rod, when high vehicle speeds, spacing lockup piston piston rod withdrawal can be made the trailing wheel locking, the stability when increasing vehicle '; When the needs tight turn radius, spacing lockup piston piston rod is stretched out releasing rear-axle steering locking, realize rear-axle steering, reduced the wearing and tearing of wheel.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 be among Fig. 1 A-A to cutaway view;
Fig. 3 is that the B of " V " shape pull bar among Fig. 1 is to structural representation.
Below in conjunction with accompanying drawing the utility model is described:
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail: as Fig. 1, shown in 2 and 3, a kind of vehicle bridge turns to the locking shifter, between two wheels, be symmetrically arranged with locking tie rod arm 1, locking transition arm 2, locking push-off pin 3 and push-off pin sleeve 4, one end of locking tie rod arm 1 is connected with the vehicle bridge steering swivel, one end of the other end and locking transition arm 2 is hinged, one end of the other end of locking transition arm 2 and locking push-off pin 3 is hinged, locking push-off pin 3 is positioned at push-off pin sleeve 4 and can moves along push-off pin sleeve 4, push-off pin sleeve 4 is fixed on the vehicle bridge 6 by support 5, between two push-off pin sleeves 4, be provided with " V " shape pull bar 7, the opening angle scalable of " V " shape pull bar 7, the top of " V " shape pull bar 7 is connected with the piston rod of spacing lockup piston 8, two open ends of " V " shape pull bar are hinged with the expansion link 9 of corresponding side respectively, expansion link 9 is positioned at push-off pin sleeve 4 and can moves along push-off pin sleeve 4, when the piston rod of spacing lockup piston 8 stretches out, the opening angle of " V " shape pull bar 7 diminishes, expansion link 9 stretches out in push-off pin sleeve 4, locking push-off pin 3 can move in push-off pin sleeve 4, but this moment, wheel was in steering state; When the piston rod of spacing lockup piston 8 was withdrawn, the opening angle of " V " shape pull bar 7 became 180 °, and expansion link 9 moves in push-off pin sleeve 4, just in time contact with locking push-off pin 3, locking push-off pin 3 can not move at this moment, thereby with the wheel steering locking, wheel can not be done divertical motion.
Above-mentioned spacing lockup piston 8 is furnished with the hydraulic efficiency pressure system of control plunger bar turnover.
Certainly, protection domain of the present utility model is not limited to the foregoing description, so long as those of ordinary skill in the art is through creatively improving, and just should be within protection domain of the present utility model.
