A left stay pipe is arranged between a left bent beam and a left inner beam of the left front beam and is connected with a shaft of a left upper cradle, wherein the shaft of the left upper cradle is composed of a shaft sleeve, a U-shaped support rod and a ball head connector, and the right front beam is correspondingly provided with a right stay pipe and a right upper cradle. The frame of a four-wheeled motorcycle with the structure of the utility model has the advantages of strong anti-collision performance of motorcycle bodies, high anti-distortion performance, good buffering effects of and big fluctuation ranges of wheels, etc., and is suitable for the running of various kinds of pavements and environment, etc.
Description
The utility model relates to technical field of motorcycles, particularly a kind of four-wheel motor vehicle carriage.
The utility model patent application a few days ago, open, the motor bike used and sold, vehicle frame adopts single reel cage to be connected with two front-wheels more, exists defectives such as anti-collision performance is poor, torsional resistance is poor, damping effect is poor, the wheel fluctuation range is little.
The goal of the invention of the utility model patent be to overcome above-mentioned defective and provide a kind of and make that the car body anti-collision performance is strong, torsional resistance is high, good damping effect, a kind of four-wheel motor vehicle carriage that the wheel fluctuation range is big.
Foregoing invention purpose of the present utility model realizes by following technical proposals:
A kind of four-wheel motor vehicle carriage, comprise: the left front beam that left camber beam, left inner beam, left bottom girder are formed, right front beam that right camber beam, right inner beam, right bottom girder are formed and lower-left reel cage, bottom right reel cage, stirrup, chain stay, several parts of the back rest are formed, it is characterized in that between the left camber beam of left front beam and left inner beam left support tube being set, left support tube is connected with the upper left reel cage axle of being made up of axle sleeve, U type pole, bulb connector; Right front beam correspondence is provided with right support tube, upper right reel cage.
In order to improve the impact resistant capability of wheel assembly before the both sides, the torsional resistance of wheel assembly before strengthening, between the left camber beam of left front beam and left inner beam left support tube is set, a left side support tube with by axle sleeve, U type pole, the upper left reel cage axle that the bulb connector is formed connects, wherein, the purpose that is provided with of axle sleeve is to realize that reel cage and support tube bonded assembly guarantee the flexible rotation of reel cage with front-wheel simultaneously, U type pole impact resistant capability and the torsional resistance that purpose is to improve wheel assembly before the both sides be set, the purpose that is provided with of bulb connector is not only to realize that reel cage is connected with front-wheel by the goat's horn axle, and provides bigger steering range for jolting of front-wheel.
In order to make front-wheel realize height self-regulated, and keep car body, between last reel cage and support tube, all be set between bottom cradle and bottom girder spool be connected not because of certain front-wheel height change causes the smooth-ride state of whole locomotive body unbalance with road surface height is different.When the road surface is higher than/is lower than the average pavement-height of car body, the masterpiece that the convex/concave road surface produces is used for wheel, impel wheel to pass through upper and lower reel cage and do upwards corresponding/rotation down along axle sleeve, application force is converted into rotational force, finally causes front-wheel highly to make corresponding automatic compensation under the situation that does not influence front-axle beam.In order to adapt to front-wheel fast, significantly jolt, guarantee that axle sleeve has good flexibility of revolution, outer bush, interior guide pin bushing, adapter shaft and protective cover are set in its axle sleeve, outer bush respectively with axle sleeve, interior guide pin bushing flush fit, keep adapter shaft in interior guide pin bushing, to rotate flexibly, the protective cover sealing and dustproof adapts to various varying environments (husky, soil) requirement to guarantee car body.
Right front beam correspondence is provided with right support tube, upper right reel cage, purpose is to make off front wheel to have above-mentioned functions equally, thereby realize that two front-wheels can be respectively regulate the front-wheel height voluntarily according to the residing pavement-height of epicycle, be in high height and another front-wheel is in and still can makes car body held stationary motoring condition under the lower position state at a front-wheel even guarantee.
Can realize height self-regulated with road surface height difference in order to make trailing wheel, and keep car body not cause the smooth-ride state of whole locomotive body unbalance because of the trailing wheel height change, a left side, right camber beam and chain stay junction are provided with adapter plate, adapter plate is by adapter shaft and by lining, needle bearing, the axle sleeve that cover of dust is formed is connected with bottom fork axis, when the road surface be higher than/when being lower than average road surface, convex/concave road surface application force makes trailing wheel act on chain stay front end axle sleeve by the rear wheel assembly and produces upwards corresponding/rotation down, realizes that trailing wheel is in the easy on and off fluctuation that does not influence under the whole locomotive body smooth-ride state.In order to adapt to trailing wheel fast, significantly jolt, guarantee that axle sleeve has good flexibility of revolution, lining, needle bearing, anchor shaft, cover of dust, needle bearing are set in its axle sleeve to match with lining, bearing, play effect lubricated, damping, anchor shaft rotates in lining flexibly, reduce friction, two ends cover of dust sealing and dustproof adapts to various varying environments (husky, soil) requirement to guarantee car body.
The external nylon jacket of described chain stay front end axle sleeve one side can prevent blockchain friction chain stay front end axle sleeve, the service life of improving car body.
The four-wheel motor vehicle carriage of the utility model structure has that the car body of making anti-collision performance is strong, torsional resistance is high, good damping effect, wheel fluctuation range are big, can be fit to advantages such as various road surfaces and environment travel.
Below in conjunction with embodiment the utility model is described in further detail.
