Abstract
The utility model discloses a rear balancing suspension assembly comprising a vehicle frame longeron, wheel axles and a steel spring plate seat. The vehicle frame longeron is supported on the wheel axles by a balancing suspension and the steel spring plate seat. The rear balancing suspension assembly is characterized in that thrusting rods are transversely arranged on the vehicle frame longeron at one side and on the middle and the rear wheel axles of the vehicle. The rear balancing suspension assembly model enables the trend and the thrust force of the transversally moving car to be transferred onto the vehicle frame via the transversal thrusting rods when the vehicle sheers on a cross-country road or on a bumpy construction site, thereby reducing damage to the rear suspension center supporting shaft and the bearing attributed to overwhelming tensile force caused by the wheel axles to the rear suspension center supporting seat via the suspension steel springs. When being mounted on the rear balancing suspension in a heavy off-road vehicle, the transversal thrusting rods have protective function to the rear balancing suspension without affecting normal functions of use thereof.
Description
Technical field
The utility model belongs to a kind of automotive suspension, specifically, is a kind of back balance suspension assembly of heavy motor vehicle.
Background technology
At present, the longitudinal of 3 and 4 general goods carrying vehicles half ellipse garden steel spring structure back balance suspension fork mechanism, the connection mode of its jackshaft and back axle and vehicle frame rear overhang crossbeam connects and keeps the installation and the athletic posture of jackshaft and back axle respectively with forward and backward each three propelling rod.Load and the carrying quality of vehicle more than 3/4 is by the left and right spring steel panel seat that is fixedly mounted on the rear overhang crossbeam center shaft and can swings, by the front and back ends of spring plate, in being supported on, on the back axle.Automobile turns to when travelling, the different driving traces of automobile front and rear wheel, in making, the back vehicle bridge produces bigger side force to rear overhang rack, this side force, usually by the left and right spring plate of rear suspension, be delivered on the vehicle frame, in forcing, the wheel of back vehicle bridge has the function of diff by spring steel panel seat and rear overhang center shaft, finish the rotation of different cireular frequencys, make Vehicular turn.Heavy-duty off-road vehicle uses at various cross-country roads and cross-country locality, and during the operation Vehicular turn, vehicle bridge is traversing to produce horizontal force by steel spring to rear overhang center crossbeam, and horizontal force causes very big damageability to rear overhang center crossbeam.Easily make whole back balance suspension distortion, even fracture can't continue to use.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of back balance suspension assembly that directly horizontal thrust is passed to vehicle frame.
The technical solution of the utility model is as follows: a kind of back balance suspension assembly, comprise chassis side rail, vehicle bridge and spring steel panel seat, and described two chassis side raiies are respectively by back balance suspension and spring steel panel seat, and symmetry is fixed on the vehicle bridge top.It is characterized in that: wherein the inboard of a chassis side rail respectively with automobile in, the back vehicle bridge be horizontally arranged with propelling rod.Make when heavy motor vehicle turns to the horizontal thrust that produces by the left and right spring plate of rear suspension, be delivered on the vehicle frame, change into and be directly passed to chassis side rail, can not cause excessive deformation, the damage of back balance suspension by spring steel panel seat and rear overhang center shaft.
Above-mentioned chassis side rail is connected with the propelling rod two ends respectively with the undersetting that the vehicle bridge top is provided with by the inboard side thrust rod bearing that is provided with.
Above-mentioned propelling rod is made of the adapter sleeve that shaft and two ends are provided with, and is equipped with the flat minor axis in the described adapter sleeve and is hinged on respectively on side thrust rod bearing and the undersetting.
Be positioned on the flat minor axis of above-mentioned adapter sleeve and be set with the buffering gum cover.Can rotate relative to adapter sleeve.Certain buffer action is arranged.
Beneficial effect: the utility model makes automobile turn to when travelling on cross-country road or rugged building site, the trend of vehicle bridge side travel and thrust, transfer on the vehicle frame through lateral rod, reduced the huge pulling force that vehicle bridge produces the rear overhang center support base through the rear overhang steel spring and the rear overhang central support shaft that causes and the damage of bearing.This lateral rod does not influence the normal functions of use of back balance suspension, and plays the protective effect to the back balance suspension after being installed on the back balance suspension of heavy off-road vehicle.
