Abstract
A rear shock absorber device for tricycle pertains to manpower or motor tricycles or wheelchairs. A main beam 1 of the frame has a fixed frame cross beam 2, each of left wheel stand 3 and right wheel stand 4 has one end hinged to the frame cross beam 2, another laterals both being fixed to a wheel shaft; the frame cross beam 2 fixes the front end of a supporting seat frame 5; the left wheel stand 3 and right wheel stand 4 support read end of the supporting seat frame 6 via the shock absorber 6. The rear shock absorber device reduces the shock to the whole vehicle, so the vehicle has small gravity excursion and may run steadily and is not prone to roll-the safety of driving is improved. Tosses of the frame have little influence on the seat, and therefore the comfort of drive is improved. The utility model has convenient maintenance, simple structure and low production cost.
Description
Technical field:
The utility model relates to manpower or three wheeled motor car, also relates to ride instead of walk the wheel Wheel-chair of usefulness of disabled person and the elderly, is the back shock absorption device of three-wheel vehicle specifically.
Technical background:
The three-wheel wheel Wheel-chair that manpower or three wheeled motor car and lower limb disability people and oldaged physically weak person use, generally all there is not back shock absorption device, the seat of wheel Wheel-chair is fixed on vehicle frame and the rear wheel frame, the vibrations that wheel is produced when walking on the road surface are directly delivered on the seat, the sense of jolting to the rider is apparent in view, owing to there is not damping, the fault rate of car is also very high.The wheel Wheel-chair that has has glissando, as connecting on the whole wheel carrier of two trailing wheels or under seat, damping spring being installed, but its damping effect is not ideal enough, take still comfortable inadequately, in the time of particularly on the inconsistent road surface of height that is in of two trailing wheels, car load is with regard to wigwag motion, and the sense of tilting is very strong, also influences the safety that the wheelchair car travels.For the lumbar vertebrae people that is ill, it is uncomfortable especially to take three-wheel vehicle, even can increase the weight of the state of an illness.
Summary of the invention
The purpose of this utility model is defective and the deficiency that overcomes existing three-wheel vehicle, and then a kind of back shock absorption device of three-wheel vehicle is provided, and it is simple in structure, and damping effect is obvious, ride comfort, steady, driving safety.
The purpose of this utility model is achieved in that the back shock absorption device of three-wheel vehicle, vehicle frame main beam is connected with rear wheel frame, rear wheel frame is provided with bumper, be fixed with cross member of frame on the vehicle frame main beam, rear wheel frame is divided into revolver frame and right wheel carrier, and an end and the cross member of frame of revolver frame and right wheel carrier are hinged, and its opposite side all is fixed on the axletree, the front end of cross member of frame fixed pedestal mounting, revolver frame and right wheel carrier support the rear end of mounting respectively through bumper.
The utility model can also be provided with buffer bush in cross member of frame and revolver frame and right wheel carrier pivotally attached axis hole.
Buffer bush described in the utility model is made by rubber.
Bumper described in the utility model is a spring damper.
The beneficial effects of the utility model are: 1, and reasonable in design, good damping effect.Change the rigid construction of vehicle frame into underslung flexible structure, rear wheel frame is divided into left and right two wheel carriers, and the position mounting spring of mounting is supported in the wheel carrier top, and wheel carrier and cross member of frame is hinged, wheel carrier can swing up and down around the cross member of frame hinge, the vibrations that produced during the operation of two trailing wheels are absorbed by separately wheel carrier and spring respectively, and the vibrations of car load are reduced, vehicle operating is steady, centre-of gravity shift is little, is difficult for producing inclination, and traveling security can improve.2, take steadily.The mounting front end is a rigid support, and the rear end is the resilient mounting of spring, and vehicle frame jolts very little to the influence of seat, and the comfort of riding increases.3, keep in repair easy.The vehicle rear wheel frame is divided into two, makes wheel be easy to change, and the maintenance of vehicle frame is also more convenient.4, simple in structure, manufacturing cost is lower.

Fig. 2 is the structural representation of cross member of frame 2 and rear wheel frame connecting portion among Fig. 1
The specific embodiment
Below in conjunction with the description of drawings and the specific embodiment the utility model is explained in detail:
Referring to Fig. 1, the back shock absorption device of three-wheel vehicle is made up of cross member of frame 2, revolver frame 3, right wheel carrier 4, bumper 5, mounting 6 and 4 hinge type structures.The front end of vehicle frame main beam 1 is captiveed joint with front fork, the rear end of vehicle frame main beam 1 is connected with rear wheel frame, can be provided with bumper 5 on rear wheel frame, is fixed with cross member of frame 2 on the vehicle frame main beam 1, cross member of frame 2 is arranged on the front lower place of mounting 6, and perpendicular with vehicle frame main beam 1.Rear wheel frame is divided into revolver frame 3 and right wheel carrier 4, revolver frame 3 and right wheel carrier 4 are made the rectangle framed structure respectively, one end and the cross member of frame 2 of its framework are hinged, place trailing wheel in the middle of the wheel carrier framework, the two ends of trailing wheel axletree, be separately fixed on the dual-side of oblong wheel carrier, form the suspension system independently be hinged on separately on the cross member of frame 2, employing bumper 5 is connected between three-wheel vehicle mounting 6 and wheel carrier.The front end of cross member of frame 2 fixed pedestal mountings 6, the inboard of revolver frame 3 and right wheel carrier 4 support the rear end of mounting 6 respectively through a bumper 5.Revolver frame 3 and right wheel carrier 4 can independently move up and down separately, absorb the shaking force that jolts from wheel, make mounting 6 remain plateau.Bumper 5 is a spring damper among Fig. 1.Bumper 5 also can adopt liquid damper or other bumper.
Referring to Fig. 2, cross member of frame 2 adopts articulated structure with revolver frame 3 and right wheel carrier 4, rear side at cross member of frame 2 is provided with four free bearings 7, front end at revolver frame 3 and right wheel carrier 4 respectively is provided with two axle sleeves 8, adopt bearing pin 10 to be horizontally through axle sleeve 8 and free bearing 7, revolver frame 3 and right wheel carrier 4 can be hinged on respectively on the cross member of frame 2, and can freely separately rotate around bearing pin 10.In cross member of frame 2 and revolver frame 3 and right wheel carrier 4 pivotally attached axle sleeves 8, be provided with buffer bush 9.Buffer bush 9 is made by rubber, also can adopt other materials making such as engineering plastics, it is shaped as tubulose, is contained between axle sleeve 8 and bearing pin 10 connecting portions, can alleviate trailing wheel and jolt, the audible noise that the metal parts collision is sent in the time of also can reducing the operation of wheel Wheel-chair the impact of vehicle frame.
