Abstract
A rear steering bridge mechanism of truck for decreasing the diameter of making a turn and the eccentric abrasion to tyres features that a steering bridge is installed for at least one wheel axle behind the rear bridge by use of the steel leaf springs and hanging lugs to connect it under the longitudinal beam. The swinging direction of its steering arm is reverse to that of the steering arm of master steering mechanism. It is possible to use its boosting hydraulic cylinder.
Description
Technical field
The present invention relates to auto steerer, especially relates to a kind of device of automobile rear steering axle.
Background technology
Existing goods carrying vehicle (except that the four-wheel steering automobile) all adopts through pair of back axle in order to improve load-carrying capacity, or increases a kind of floating type vehicle bridge in the front or the back of two (list) back axle, perhaps adopts the multi-axle steering propons.Its turning efficiency directly influences the service life of maneuverability, turning-circle diameter, road-holding property, economy and the tire of automobile.
Summary of the invention
Purpose of the present invention 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 device of the automobile rear steering axle of manufacturing cost.
Solution of the present invention is such: at least one rear steering axle is arranged after automobile axle, and 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.
Advantage of the present invention is: increase steeraxle by the back at automobile axle, can shorten the wheelbase of automobile, reduce turning-circle diameter, improve the maneuverability of running car and the reasonableness of carrying.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.

The specific embodiment
Propons 1, back axle 2, steeraxle 3, steel spring 4, hinge of leaf spring 5, chassis side rail 6, wheel and tire 7, direction machine deflector 8, steering drop arm 9, steering side tube 10, track arm 11, transition longitudinal tie 12, transition steering drop arm 13, power-assisted hydraulic ram 14 have been the present invention includes.
At least one rear steering axle is arranged after automobile axle, and rear steering axle all is connected the lower end of chassis side rail with steel spring, hinge of leaf spring; Rear steering axle steering hardware be to be connected with direction machine deflector 6; The swaying direction of the transition steering drop arm 13 of rear steering axle is opposite with the swaying direction of direction machine steering drop arm 9.
The steering hardware of rear steering axle all has transition steering drop arm 13, is hinged with steering side tube 10 on transition deflector plumbing arm 13, and the other end of longitudinal tie 10 and track arm 11 are hinged;
Transition steering drop arm 13 in the rear steering mechanism is hinged with the steering drop arm 9 in the Front Axle Steering Mechanism with transition longitudinal tie 12, transition steering drop arm 13 is 15 with the hinge-point of vehicle frame, therefore just the sense of motion with steering drop arm 9 is opposite for the sense of motion of transition steering drop arm 13, thereby the tire pure rolling that realizes rear steering axle is travelled.
In the present embodiment, the transition steering drop arm 13 in the rear steering mechanism is hinged with transition steering drop arm 13 successively with transition longitudinal tie 12.On described transition steering drop arm 13, be hinged with power-assisted hydraulic ram 14.
In embodiments of the invention shown in the accompanying drawing (1,2), the two ends, the left and right sides and the steel spring 4 of steeraxle 3 are hinged, and are hinged on the chassis side rail 6 by hinge of leaf spring 5.The track arm 11 of steeraxle 3 left ends is hinged with steering side tube 10, the other end of steering side tube 10 is connected with the bottom of transition steering drop arm 13, the hinged transition longitudinal tie 12 in the upper end of transition steering drop arm 13, the other end of transition longitudinal tie 12 and steering drop arm 9 are hinged.The middle part of transition steering drop arm 13 and power-assisted hydraulic ram 14 are hinged, and the other end of power-assisted hydraulic ram 14 is hinged on the upper end of chassis side rail 6, constitute rear-mounted first steeraxle and steering hardware.The middle and upper part of transition steering drop arm 13 and power-assisted hydraulic ram 14 are hinged, the other end of power-assisted hydraulic ram 14 is hinged on the chassis side rail 6, the hinged transition longitudinal tie 12 in transition steering drop arm 13 upper ends, the lower end of transition steering drop arm 13 and steering side tube 10 are hinged, the other end of steering side tube 10 and track arm 11 are hinged, the two ends, the left and right sides of steeraxle 3 and the middle part of steel spring 4 are hinged, and be installed on the chassis side rail by hanger 5 before and after the steel spring, constitute second rear-mounted axle steer bridge and the steering hardware.Transition steering drop arm in the two above-mentioned axle steer bridges 13 usefulness transition longitudinal ties 12 are connected in turn promptly form the multi-axle steering bridge, therefore, be with transition longitudinal tie 12 pivotally attached structure successively between steering drop arm 9 in the present embodiment steering hardware and the transition steering drop arm 13.
In manufacturing process, multiaxis rear steering axle of the present invention is mounted in the back of back axle, shown in figure (3,4).
