Abstract
The utility model discloses a tricycle hydraulic pressure front shock absorbing device, the front shock absorbing device used for the tricycle comprises four absorbers. A main absorber (2) and a sub-absorber (21) are respectively fixed at the two sides of front wheels. The main absorber (2) is parallel to the sub-absorber (21), and a lower fulcrum is connected with a wheel axle. The bolts (9) used for the upper fulcrums of the two main absorbers (2) and the two sub-absorbers (21) are connected with an upper connection plate (3). A spacing is provided between the upper connection plate (3) and a lower connection plate (8). Five holes are provided on the lower connection plate (8). The main absorber (2) and the sub-absorber (21) respectively perforated through the holes on the lower connection plate (8), and fixed with bolts (7) with the lower connection plate (8). The utility model overrides the disadvantages that the hock absorbing effect of the current tricycle is not ideal and the absorber is easy to be damaged; the utility model provides a front shock absorbing device with simple structure, good shock absorbing performance, high impact bearing intension and long service life, and is applied to the motor tricycle.
Description
Technical field
The utility model relates to a kind of shock absorption device, especially a kind of front damping device of motor-tricycle.
Background technology
Motor-tricycle because its low price is flexible, is used widely in the rural area.But these roads in rural area are often relatively poor, and the road surface is uneven.What the shock absorption device of existing motor-tricycle used is the bumper of two-wheeled motor vehicle.Because the motor-tricycle front has only a wheel, the impulsive force that the poor stability of front-wheel, front shock absorber afford is big, and damping effect is undesirable, and bumper damages easily.
Summary of the invention
The utility model has overcome the deficiencies in the prior art, provides that a kind of damping performance is good, the motor-tricycle front damping device of long service life.
For solving above-mentioned technical matters, the utility model by the following technical solutions:
A kind of tricycle hydraulic front damping device, the front damping device that this motor-tricycle uses is made of four bumpers.Fix a main bumper 2 and an attached bumper 21 respectively in the both sides of front-wheel.Main bumper 2 is parallel with attached bumper 21, and lower fulcrum and wheel shaft link together.The last fulcrum of two main bumpers 2 and two attached bumpers 21 is connected with upper plate 3 with bolt 9.Have between upper plate 3 and the lower plate 8 at interval.Have five holes on the lower plate 8.Main bumper 2 and attached bumper 21 pass the hole on the lower plate 8 respectively, and be fixing with lower plate 8 by bolt 7.Axis of orientation 1 passes the hole on the lower plate 8, and is fixing with upper plate 3.
Further technical scheme is that main bumper 2 is made of spring locating bush 5, trip ring 6, hydraulic damping bumper 22, outer spring 4.Spring locating bush 5 nestles up lower plate 8, and trip ring 6 is fixed on outside the hydraulic damping bumper 22, and outer spring 4 is enclosed within outside the hydraulic damping bumper 22, and is fixed between spring locating bush 5 and the trip ring 6.
Further technical scheme is that attached bumper 21 is hydraulic damping bumpers 22.
Compared with prior art, the beneficial effects of the utility model be simple in structure, damping performance good, the intensity that withstands shocks is big, the life-span is permanent.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is that the B of Fig. 1 is to figure.
Fig. 3 is that the C of Fig. 1 is to figure.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further elaborated.
Because the load carrying ability of motor-tricycle is big, the road injustice of travelling, the impulsive force that is subjected to is big, and the rigidity of its damping spring can not be too little, otherwise the load-carrying capacity of bumper is not enough, makes bumper than damage early easily.But the rigidity of damping spring is excessive, can strengthen the impact to the bumper inner body again, causes the early failure of bumper.Hydraulic damping then can extraordinaryly eliminate vibration, side force.Therefore the utility model adopts main bumper 2 with attached bumper 21 dampings.Main bumper 2 is when making back and forth movement, and attached bumper 21 is also being followed and made back and forth movement, can better absorb vibration, drives comfortable.
Motor-tricycle is a triangular structure, and the phenomenon of left and right beat often appears in front-wheel poor stability, wheel.The utility model master bumper 2 is parallel to each other with attached bumper 21, last fulcrum is fixed on lower plate 8 and the upper plate 3, and lower fulcrum interconnects by wheel shaft, forward and backward bumper moves simultaneously can increase the steadiness of front-wheel, the suffered side force of shock absorption device can be disperseed by actv. simultaneously, and actv. solves left and right beat problem.
Installation of the present utility model and plumb bob vertical have the angle of 25 degree, can prevent that bumper, vehicle frame, chain stay from rupturing.
