Abstract
The utility model discloses a support axle for heavy-duty vehicle, in particular to a steering reset device for servo steering support axle for heavy-duty car vehicle. The steering reset device for servo steering support axle comprises an I-shaped beam, steering knuckles at both ends of the beam, and a cross tie whose both ends connecting with both ends of the I-shaped beam. The utility model is characterized in that one side of the I-shaped beam is provided with a shock damper whose periphery is a return spring, both ends of the shock damper are shock damper brackets, and both ends of the return spring are spring bases. In order to prevent the abrasion of the servo steering axle caused by the swinging of the wheels when the vehicle runs in a straight line on the bumpy road, a servo steering shock damper is added on the servo steering axle; and to guarantee the straight line driving state, wheel mid position retaining-springs are added, which is helpful to reset the steering rear wheels.
Description
(1) technical field
The utility model relates to a kind of heavy motor vehicle with supporting bridge, and particularly a kind of heavy motor vehicle follow-up steering supporting bridge turns to returning device.
(2) background technology
Because GB1589-2004 carries out, multiaxle truck more and more receives publicity, and in order to guarantee the divertical motion requirement of multi axle car, reduces turn radius, prolongs the service life of tire and each parts, generally adopts many bridges steering hardware.But the leverage that many bridges turn to, the layout of pipeline are all very complicated, now a lot of multiaxis vehicles have all adopted following steering axle, during Vehicular turn, the follow-up steering mechanism of following steering axle will make the both sides wheel produce corresponding deflection angle along the movement tendency of vehicle center of gyration, make each wheel of automobile carry out divertical motion, the wear on tyres when having avoided turning to around a certain instantaneous center as far as possible.Owing to there is above-mentioned advantage, following steering axle has obtained using abroad morely at present.But following steering axle tire swing when the straight-line travelling Uneven road can produce wearing and tearing; Simultaneously, turning to rear wheel to be difficult for very fast return.
(3) summary of the invention
The utility model provides a kind of follow-up steering supporting bridge that can make wheel just return, prevent wobbling of wheels rapidly to turn to returning device in order to remedy the deficiencies in the prior art.
The utility model is achieved by the following technical solution:
A kind of follow-up steering supporting bridge turns to returning device, the steering swivel that comprises H-girder and its two ends, there are intermediate rod two ends to be connected with the H-girder two ends, its special character is: described H-girder one side is provided with bumper, the bumper periphery is a pull back spring, the bumper two ends are shock absorber support, and the pull back spring two ends are spring perch.
Follow-up steering supporting bridge of the present utility model turns to returning device, and the two ends spring perch is associated on the shock absorber support by two bearing pins; One end shock absorber support is associated on the steering swivel of following steering axle by the brake shoe brake cheek rest pin of lengthening, and other end shock absorber support is associated on the H-girder of following steering axle by double end stud.
For preventing that following steering axle tire swing when the straight-line travelling Uneven road from producing wearing and tearing, increases the follow-up steering shock absorber on following steering axle; For guaranteeing the straight-line travelling state, increase the tire meta and keep spring, help turning to the return of rear wheel.
(4) description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is a schematic top plan view of the present utility model;
Fig. 2 looks scheme drawing for master of the present utility model.
Among the figure, 1 steering swivel, 2 brake shoe brake cheek rest pins, 3 shock absorber supports, 4 spindle arms, 5 bearing pins, 6 spring perches, 7 bumpers, 8 pull back springs, 9 intermediate rods, 10 H-girders.
(5) specific embodiment
Fig. 1, Fig. 2 are a kind of specific embodiment of the present utility model.This embodiment comprises the steering swivel 1 at H-girder 10 and its two ends, has an intermediate rod 9 two ends to be connected with H-girder 10 two ends, and H-girder 10 1 sides are provided with bumper 7, and bumper 7 two ends are shock absorber support 3; Shock absorber support 3 is linked on the steering swivel 1 by the brake shoe brake cheek rest pin 2 of lengthening, and the position, hole that shock absorber support 3 utilizes H-girder 10 that leaf spring is installed is attached on the H-girder 10 by thru-bolt.Pull back spring 8 installs on the steering anti-kickback snubber 7 by two spring perches 6, and as an assembly, this assembly is linked on the shock absorber support 3 by two bearing pins 5.
When vehicle turned in the process of moving, ground made wheel steering for the side force of wheel, and during straight-line travelling, bumper 7 and pull back spring 8 are just returning wheel rapidly behind the wheel steering; Vehicle is when straight-line travelling, and wheel can swing when running into uneven road surface, and bumper 7 can prevent the swing of wheel; To guarantee the straight-line travelling of wheel.
