The automobile with the rear mounted steering axle has the advantages of shortening automobile shaft distance and can reduce swerve diameter and can improve the flexibility for driving and the reasonability for bearing of the automobile; and the steering axle is linked with the traversing mechanism redirector synchronously to rotate, to reduce the eccentric wearing to tyres when the automobile is swerved, thereby prolonging the service life of the tyre, lightening the self weight of the automobile, improving the carrying capacity and reduce manufacturing cost.
Description
Technical field
The utility model relates to auto steerer, especially relates to a kind of automobile of rear steering axle.
Background technology
Existing goods carrying vehicle is in order to improve load-carrying capacity, and all adopting in the front or the back of two (list) back axle increases a kind of floating type vehicle bridge, perhaps adopts the multi-axle steering propons.The operability and the maneuverability of automobile are poor.
Summary of the invention
The purpose of this utility model just provides a kind of multi-axle steering automobile that can be used in one or one above steeraxle postposition, solve the reasonableness that existing automobile axle load distributes, reduce turning-circle diameter, improve the maneuverability of running car, reduce the automobile of the rear steering axle of manufacturing cost.
Solution of the present utility model is such: after the front of automobile axle or back at least one rear steering axle is arranged, rear steering axle all is connected the lower end of chassis side rail with steel spring, hinge of leaf spring;
The steering hardware of rear steering axle is to be connected with the deflector of direction machine, is driven by the deflector of direction machine and rotates; The swaying direction of the transition steering drop arm of rear steering axle is opposite with the swaying direction of direction machine steering drop arm, and tire is turned to synchronously, to increase the maneuverability of automobile.
In such scheme, the steering drop arm in the rear steering mechanism can be hinged with steering drop arm successively with the transition longitudinal tie; On described transition steering drop arm, can be hinged with the power-assisted hydraulic ram.
The utility model has the advantages that: increase steeraxle by front or back, can shorten the wheelbase of automobile, reduce turning-circle diameter, improve the maneuverability of running car and the reasonableness of carrying at automobile axle.Adopt the transition longitudinal tie to connect each axle steer mechanism, make automobile when turning driving, tire can turn in synchronous interaction, reduces the eccentric wear of tire, improves the service life of tire, and can alleviate automotive dead weight, improves load-carrying capacity, reduces manufacturing cost.
