Abstract
The invention discloses an off-road vehicle with an underpan height adjusting function. The off-road vehicle comprises an off-road vehicle body, wherein gearboxes for controlling the wheel rotation are respectively arranged at the front side and the back side of an underpan, the two sides of each gearbox are respectively in transmission connection with wheels through a transmission shaft, each of the two sides of each gearbox is respectively hinged to a group of wheel swinging frames capable of vertically swinging, the number of the wheel swinging frames in each group is two, the two wheel swinging frames are respectively positioned at the upper side and the lower side of the corresponding transmission shaft, hydraulic oil cylinders are respectively hinged to positions, positioned at the two sides of the front and back gearboxes, of the bottom of the underpan, and a piston rod of each hydraulic oil cylinder is respectively and downwards inclined and is hinged to the corresponding wheel swinging frame positioned at the lower side of the transmission shaft. The off-road vehicle has the advantages that the structure is simple, the design is reasonable, the piston rods of the hydraulic oil cylinders act on the wheel swinging frames, and the height adjustability of the underpan of the vehicle body is realized, so the off-road vehicle can be used in various complicated road conditions, the underpan scratching is avoided, and the service life of the off-road vehicle is prolonged.
Description
technical field:
The present invention relates generally to cross-country car technical field, particularly relate to a kind of chassis height adjustable cross-country car.
background technology:
In prior art, cross country chassis height is fixed, and can not adapt to the road surface of road conditions complexity, causes cross country chassis to be easily scratched, and affects the adaptation life-span of cross-country car.
summary of the invention:
The object of the invention is exactly the defect in order to make up prior art, provide a kind of chassis height adjustable cross-country car.
The present invention is achieved by the following technical solutions:
The cross-country car that chassis height is adjustable, includes cross-country car car body, it is characterized in that: be separately installed with the change speed gear box controlling vehicle wheel rotation before and after the tray bottom of cross-country car car body, the both sides of each change speed gear box are connected with wheel drive respectively by transmission shaft; The both sides of each change speed gear box are all hinged with one group of wheel wobble frame that can swing up and down, and often organize wheel wobble frame and include two, lay respectively at the upper side and lower side of corresponding transmission shaft; The position that described tray bottom is positioned at forward and backward change speed gear box both sides is hinged with hydraulic ram respectively, and the piston rod of each hydraulic ram is all tilted to down and is hinged on the corresponding wheel wobble frame be positioned on the downside of transmission shaft.
The cross-country car that chassis height is adjustable, is characterized in that: described wheel wobble frame is V-type; The both sides of forward and backward change speed gear box are all hinged with a pair hydraulic ram, and the piston rod front end of often pair of hydraulic ram is hinged on the supported on both sides arm of corresponding wheel rocking carrier respectively.
The cross-country car that chassis height is adjustable, is characterized in that: four hydraulic rams near body inner side are all communicated with oil pump one by oil inlet outward; Two hydraulic rams being positioned at car body forefront are communicated with oil pump two by oil inlet; Be positioned at two hydraulic rams of car body rearmost by oil inlet and oil pump tee joint.
The cross-country car that chassis height is adjustable, is characterized in that: described chassis is provided with the part-time case be in transmission connection by transmission shaft and change-speed box.
The cross-country car that chassis height is adjustable, is characterized in that: the extending area of hydraulic ram upper piston rod is respectively installed with damping spring.
The present invention is filled with high pressure oil by oil pump in hydraulic ram, and the piston rod of hydraulic ram is stretched out, and because the position of wheel is fixed, so hydraulic cylinder piston rod can act on corresponding wheel wobble frame, forces chassis to raise, otherwise then chassis declines.So, the adjustable for height object of cross country chassis is achieved.
In addition, because oil pump one controls four hydraulic rams, so, when the hydraulic ram of oil pump one only to car body side is oil-filled, the object of tilting of car body just can be realized.
Described oil inlet is separately installed with control cock.
Advantage of the present invention is:
Structure of the present invention is simple, reasonable in design, is acted on wheel wobble frame, achieves the adjustable of chassis of vehicle body height, make cross-country car use various complex road condition, avoid chassis to swipe, extend the service life of cross-country car by the piston rod of hydraulic ram.
accompanying drawing illustrates:
Fig. 1 is birds-eye view of the present invention.
