Abstract
The utility model relates to a front wheel damper for a motor tricycle and belongs to the damper technical field. The utility model solves the technical problem of providing a front wheel damper for a motor tricycle which has long service life and avoids the phenomenon that the front wheel does not incline to one side or swing left and right when the motor tricycle runs. The technical proposal is that the utility model comprises a damping corbel piece and a damping spring, wherein the damping corbel piece is a lever type damping corbel piece, the fulcrum of which is provided with a connecting piece to be connected with a frame of the motorized tricycle. A heavy arm end is provided with a connecting piece to be connected with a slewing journal of the front wheel of the motor tricycle; a lever of force is connected with the damping spring. The structure and form of the traditional damper are changed, the utility model is of low fault rate and long service life, and can guarantee that performance is stable when the motor tricycle runs and that the front wheel does not incline to one side or swing left and right. The utility model is applicable to the front wheel damping of the motor tricycles.
Description
Technical field
The utility model relates to a kind of three wheeled motor car front-wheel bumper, belongs to the bumper technical field.
Background technology
Chinese patent ZL99200149.8 discloses a kind of reaming type scale-up version bumper, upper and lower lining and silk braid are arranged on its bumpar post, on the bumpar post of silk braid below outside framework oil seal is housed, be set with damping spring and damping cylinder outward, although it is on existing bumper structure, change damping cylinder into enlarging, top and bottom are the inverted cone shape transition and connect, bumpar post changes the enlarging form into the targeting part that overlaps of damping cylinder, the overstriking bumpar post, though its assembly load-carrying capacity increases, it still exists following deficiency: dust cap, oil sealing are fragile; When pasta is inconsistent in the oil sealing leakage of oil causes two damping cylinders, can cause two damping spring unbalance stress, vehicle in motion, front-wheel can occur to a lateral deviation tiltedly or the phenomenon that swings.In addition, because wearing and tearing, the service life of bumpar post is still shorter.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of three wheeled motor car front-wheel bumper, this bumper long service life, and can guarantee three wheeled motor car in motion, front-wheel can not occur to the lopsidedness or the phenomenon that swings.
It is as follows to solve the problems of the technologies described above the technical scheme that is adopted:
A kind of three wheeled motor car front-wheel bumper, it comprises damping support arm and damping spring, and said damping support arm is a lever damping support arm, and the fulcrum place of damping support arm is provided with attaching parts, so that be connected with the motor tricycles vehicle carriage.Gravity arm end portion is provided with attaching parts, so that be connected with the three wheeled motor car front wheel knuckle, arm of force end is connected with damping spring.
Above-mentioned three wheeled motor car front-wheel bumper, the attaching parts at said support arm fulcrum place is the hinge cover, and is hinged with being connected to of motor tricycles vehicle carriage, and the set attaching parts of gravity arm end portion is an adapter sleeve, captive joint with being connected to of damping spring in arm of force end, damping spring is a leaf spring.
Above-mentioned three wheeled motor car front-wheel bumper, the weighing arm of said lever damping support arm and arm of force branch are located at the both sides of fulcrum place attaching parts.
Above-mentioned three wheeled motor car front-wheel bumper, the weighing arm of said damping support arm and the arm of force are located at the homonymy of fulcrum place attaching parts.
Above-mentioned three wheeled motor car front-wheel bumper is provided with the hydraulic damping device between damping support arm and vehicle frame.
Three wheeled motor car front-wheel bumper provided by the utility model has changed the version of traditional shock absorber, and fault rate is low, and long service life can guarantee three wheeled motor car stable performance in motion, front-wheel can not occur to the lopsidedness or the phenomenon that swings.The utility model is applicable to the front-wheel damping of three wheeled motor car.

The specific embodiment
Below in conjunction with the embodiment accompanying drawing, the utility model is described in further detail:
Referring to Fig. 1-Fig. 3, this three wheeled motor car front-wheel bumper comprises damping support arm and damping spring, the damping support arm is a lever damping support arm 6, the fulcrum place of this support arm is established attaching parts 1 and is the hinge cover, so that it is hinged with motor tricycles vehicle carriage 9, the set attaching parts 3 in weighing arm 5 ends is an adapter sleeve, be connected with three wheeled motor car front-wheel 2 steering swivels 4, the arm of force 7 ends link to each other with damping spring 8, and this place can adopt ralocatable mode to connect, and also can adopt fixed form to connect, but preferred fixed form connects, as Fig. 2, shown in Figure 3, adopt U type screw rod 11, clamping plate 12 and nut 10 are fixing, use more reliable.Damping spring 8 can be selected cylindrically coiled spring for use, also can select leaf spring for use, and this can decide according to the concrete structure of motor tricycles vehicle carriage 9.In the ordinary course of things, preferably select leaf spring for use, because of leaf spring long service life, reliable operation.Between damping support arm 6 and vehicle frame 9, also can establish the hydraulic damping device, with further raising damping effect.
In addition, position between the attaching parts hinge cover at damping support arm 6 fulcrum places and the damping spring 8 of the arm of force 7 ends can exchange, be that the weighing arm 5 and the arm of force 7 can divide the both sides that are located at support arm 6 fulcrum place hinge covers, also can make the weighing arm 5 and the arm of force 7 be located at the homonymy of lever damping support arm 6 fulcrum place hinge covers.That is hinge cover 1 is located at an end of support arm 6, and damping spring 8 is located at the middle part of support arm 6.This concrete structure situation by vehicle frame is decided.
Referring to Fig. 4, Fig. 5, concrete structure situation according to motor tricycles vehicle carriage 9, lever damping support arm 6 can be made into dihedral, equally, the attaching parts hinge cover at the fulcrum place of support arm 6 is hinged with vehicle frame 9, the adapter sleeve of weighing arm 5 ends is connected with the steering swivel 4 of front-wheel 2, and the arm of force 7 ends are fixing with damping spring 8 with U type screw rod 11, clamping plate 12 and nut 10.
