Abstract
The invention relates to a back-bridge off-road vehicle chassis with automatically-adjusted wheels, and belongs to the technical field of automobile manufacturing. The back-bridge off-road vehicle chassis comprises a back bridge for bearing a vehicle body, wherein a back-bridge front half shaft is installed at the front end of the back bridge. The front end of the back-bridge front half shaft is connected with a front-bridge swaying frame, and the rear end of the back-bridge front half shaft is connected with a front hydraulic swaying regulator. A back-bridge rear half shaft is installed at the rear end of the back bridge, the rear end of the back-bridge rear half shaft is connected with a back-bridge swaying frame, and a rear hydraulic swaying regulator is installed at the front end of the back-bridge rear half shaft. The front hydraulic swaying regulator is connected with the rear hydraulic swaying regulator through a hydraulic system, two sides of the front-bridge swaying frame are connected with front wheels, and two sides of the back-bridge swaying frame are connected with rear wheels. When the off-road vehicle chassis runs on a road surface with a large high-low difference, each wheel can automatically regulate the height so as to adapt to the uneven ground. In addition, when the vehicle runs, no matter which wheel is raised or lowered, the raising/lowering height of the vehicle are about one half of that of the wheel. Compared with the prior art, the vehicle is reduced by one half in the bumping degree, so that a driver and passengers are more comfortable.
Description
Technical field:
The present invention relates to field of automobile, relate in particular to a kind of wheel self-align spine bridge cross country chassis.
Background technology:
Modern automobile is more and more paid attention to the traveling comfort taken, so that the customer often classifies the traveling comfort of car as an important criterion that water is bought.Particularly for cross-country car, when passing through high mountain, valley, desert, rainforest area, if go on difference of height king size road surface; Wheel can be because of receiving heavy uneven skidding; Even unsettled, thus the propelling thrust of wheel reduced, even lose propelling thrust; Greatly reduce the carrying capacity of vehicle, and navigating mate and passenger's sensation are jolted with uncomfortable very much.For improving the problem that influences vehicle performance because of Uneven road, suspension has played key role.
Suspension is the general name of the vehicle frame and all the power transmission connecting devices between vehicle bridge or the wheel of automobile; Its effect is that power and the power of transfer function between wheel and vehicle frame is turned round; And buffering is passed to the impulsive force of vehicle frame or vehicle body by uneven road surface; And the vibration that decays and cause thus, can put down with the assurance automobile and " go page or leaf.
Suspension is divided into stand alone type suspension and vertical hanging not merely.Wherein, the wheel of independent suspension is contained in the two ends of a whole axletree, when sidecar wheel running is beated, will influence the opposite side wheel and also beat accordingly, makes whole body vibrations or inclination.
The axletree of stand alone type suspension is divided into two sections; Give wheel for every and be installed in independently below the vehicle frame with coil spring, when a sidecar wheel bounce or jump, the another side wheel is not involved; The vibration of vehicle body artificially reduces; Car comfort also is able to very big lifting, and existing cross-country car uses the stand alone type suspension mostly, to overcome the adverse effect that Uneven road brings.
Yet the cross country chassis of this kind structure still has certain limitation, the sense of jolting when can only to eliminate the road surface difference of height be not very big, and the vehicle obstacle climbing ability neither be very high.And during vehicle conduct in the open air, run into the bigger situation of road surface height margin through regular meeting, and the vehicle sense of jolting is still very strong, and the vehicle body swing amplitude is still very big, even vehicle can't at all can't clear an obstacle.
Summary of the invention:
Technical matters to be solved by this invention is to overcome the defective of prior art, and a kind of wheel self-align spine bridge cross country chassis is provided, and to overcome the limitation of present cross-country car damping performance, improves the whole obstacle climbing ability and the comfort level of cross-country car.
Technical matters to be solved by this invention adopts following technical scheme to realize.
