Abstract
The utility model relates to an auto whose rearmost axle is provided with a steering axle, characterized in that a multiaxial steering axle is added on the rearmost axle of a 4*2, 6*4, 6*2 (double front axles and single rearmost axle) cargo, the front end or the rear end or both the front and rear end of the rearmost axle are provided with a steering axle with at least one axle, the structure of the steering axle is that an armor plate spring and an armor plate lifting lug are connected with the lower part of the longeron of the frame, on end of the hydraulic ram is articulated with the steering knuckle arm of the steering axle, the other end of the hydraulic ram is deadly arranged on the steering axle or on the frame; hydraulic redirector operates the steering axle to change direction simultaneously so as to realize the tyres to change direction simultaneously. The utility model is characterized in that the flexibility of the steering of an auto is improved by adding a steering axle at the front end or the rear end, by adopting the structure that the hydraulic ram and the traversing mechanism hydraulic power motor change direction simultaneously, enabling the tyres to change direction simultaneously and gangedly when the auto is turning at corners, reducing the scouring to the tyres, prolong the working life of tyres and lowering the manufacturing cost.
Description
Technical field
The utility model relates to the automobile of a kind of back Biodge device steeraxle.
Background technology
Existing goods carrying vehicle (except that the four-wheel steering automobile) is in order to improve load-carrying capacity, all adopt through pair of back axle, or increase a kind of floating type vehicle bridge in the front end or the rear end of two (list) back axle, or increasing the vehicle bridge that can not turn to, its maneuvering performance directly influences the service life of road mobility, turning-circle diameter, road-holding property, economy and the tire of automobile.
Summary of the invention
The purpose of this utility model just provides a kind of multi-axle steering automobile that one or above steeraxle are installed in front end, the rear end of automobile axle or steeraxle is installed in the front and back end of automobile axle that can be used in, solve the reasonableness that existing automobile axle load distributes, improve the manoevreability of running car, reduce the automobile of the back Biodge device steeraxle of manufacturing cost.
Solution of the present utility model is such: existing 4 * 2,6 * 4, increase the multi-axle steering bridge on the basis of 6 * 2 (two propons list back axle) goods carrying vehicle back axle, promptly be provided with and have one steeraxle at least in the front end of back axle or rear end or in the front and back end of back axle, this steeraxle is the lower end that is connected chassis side rail with steel spring, hinge of leaf spring, have the steering hydraulic oil cylinder, hydraulic ram one end and steeraxle track arm are hinged, and the other end is fixed on steeraxle or the vehicle frame; The steering hydraulic oil cylinder is connected with the deflector of direction machine hydraulic power, and the rotation direction of drive steeraxle and the rotation direction of propons are handled steeraxle by hydraulic power steering device when turning to and rotated simultaneously in the same way, realize that tire turns to synchronously.
The utility model has the advantages that steeraxle by increase at least one in front end, rear end or the front and back end of automobile axle, improve the maneuverability of running car, adopt hydraulic steering cylinder and direction machine hydraulic power device to turn to synchronously, make automobile when turning driving, tire can turn in synchronous interaction, reduce the eccentric wear of tire, improve the service life of tire, reduce manufacturing cost.
