Abstract
A rear axle main reducer jacket device for right three-wheeled and right five-wheeled motorcycles comprises a main reducer jacket, connecting surfaces, a reinforcing rib, a rear cover and pipe orifices. The main reducer jacket is a shuttle shell, a circular cavity is formed in the middle of the main reducer jacket, the rear cover corresponding to the circular cavity is arranged on the main reducer jacket, the pipe orifices are formed in two ends of the main reducer jacket respectively, the connecting surfaces are arranged on two sides of the main reducer jacket, and the pipe orifices in the two ends of the main reducer jacket correspond to an axle. The shear resistance of the rear axle main reducer jacket is improved, the main reducer jacket cannot deform when more freights are carried, and unnecessary harm is avoided.
Description
Technical field
The utility model relates to motorcycle Biodge device, and especially a kind of back axle master for positive three-wheel and five wheel motorcycle subtracts involucrum device.
Background technology
At present, five wheel motorcycle back axle is all used motor tricycle back axle, because right three-wheeled motorcycle carframe girder spacing is large, vehicle frame main beam, spring plate, spring block are all positioned at back axle two ends root, and the load of car load is all at spindle nose position like this, and car load travels steadily, easy to use, price is lower, is deeply subject to numerous clients' love and esteem, go out ride instead of walk or transport use very convenient.But, along with the variation of the market demand, need to transport more goods, the weight increase of goods can cause tire overload to break, steel ring modification, easily cause traffic accident, five wheel motorcycle can carry more goods by meet requirements, but five wheel motorcycle rear axle structure is identical with motor tricycle rear axle structure, because five wheel motorcycle vehicle frame main beam spacing is little, vehicle frame main beam, spring plate, spring block is all positioned at back axle master and subtracts the two ends of involucrum, force the load of car load too much to act on main subtracting on involucrum, in motorcycle driving process, run into and overturn or road when sudden change, will cause back axle master to subtract involucrum modification, internal gear damages or rear axle shaft fracture.
The patent document that is 201320253566.6 through retrieval request number has been announced a kind of micro-vehicle rear-axle casing, on bonnet and back axle involucrum, fix brace panel, brace panel is triangle ramp structure, this structure is not suitable for positive three-wheel or five wheel motorcycle, the load of car load all act on main subtract on involucrum after, easily cause the main involucrum modification that subtracts, cause injury accident.
In view of the foregoing, the structure that existing back axle master subtracts involucrum needs to improve.
Utility model content
The purpose of this utility model is in order to overcome deficiency of the prior art, provide a kind of back axle master for positive three-wheel and five wheel motorcycle to subtract involucrum device, improve the anti-shear ability that back axle master subtracts involucrum, when the more goods of carrying, ensure that master subtracts not modification of involucrum, has avoided the generation of unnecessary injury.
The utility model to achieve these goals, adopts following technical scheme: a kind of back axle master for positive three-wheel and five wheel motorcycle subtracts involucrum device, be by: mainly subtract involucrum, joint face, reinforced rib, bonnet, the mouth of pipe forms; It is fusiformis housing that master subtracts involucrum, and the main middle part that subtracts involucrum arranges circular cavity, and master subtracts corresponding circular cavity on involucrum bonnet is set, the main two ends that subtract involucrum respectively arrange the mouth of pipe, the main both sides that subtract involucrum are joint face, the main mouth of pipe setting corresponding to axletree that subtracts involucrum two ends, and the diameter of the mouth of pipe is 60-61mm.
The corresponding circular cavity in middle part of described joint face is set to arc surface, and the both sides of joint face arc surface are set to straight line plane, and the straight line plane of joint face both sides and the arc surface line correspondence at middle part are tangent.
The straight line in-plane correspondence of described joint face both sides arranges reinforced rib, and two reinforced ribs on joint face are symmetrical, and reinforced rib is protruding arc surface, and the height of reinforced rib is 4-6mm.
The beneficial effects of the utility model are: Five wheel and motor tricycle back axle subtract most of Action of Gravity Field on involucrum assembly in back axle master bearing after weight, carry out loss of weight by disymmetry reinforced rib with symmetrical two the tangent straight line planes of arc surface, make main modification and eliminating stress not when subtracting involucrum and being hit, while having avoided bearing sudden change, master subtracts the joint face bending deformation of involucrum, greatly increase the service life of back axle, in the time bearing sudden change, shearing force and impulsive force are scattered on axle housing simultaneously, reduce back axle and bear the shearing force while sudden change, prevent bridge tube bending, master subtracts gear breakage, half axle fracture, eliminate safe hidden trouble.Simple in structure, driver and crew's safety factor is obviously improved, be applicable to promoting the use of.
Brief description of the drawings
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Fig. 1 is, general assembly structural representation;
Fig. 2 is to look up structural representation;
Fig. 3 is, A-A cross-sectional view in Fig. 1;
In Fig. 1,2,3: master subtracts involucrum 1, joint face 2, reinforced rib 3, bonnet 4, the mouth of pipe 5.
Detailed description of the invention
Below in conjunction with accompanying drawing and detailed description of the invention, the utility model is described in further detail:
As shown in the figure, the main involucrum 1 that subtracts is for fusiformis housing, the main middle part that subtracts involucrum 1 arranges circular cavity, master subtracts corresponding circular cavity on involucrum 1 bonnet 4 is set, the main two ends that subtract involucrum 1 respectively arrange the mouth of pipe 5, the main both sides that subtract involucrum 1 are joint face 2, the main mouth of pipe 5 setting corresponding to axletree that subtracts involucrum 1 two ends, and the diameter of the mouth of pipe 5 is 60-61mm.
The corresponding circular cavity in middle part of described joint face 2 is set to arc surface, and the both sides of joint face 2 arc surfaces are set to straight line plane, and the straight line plane of joint face 2 both sides and the arc surface line correspondence at middle part are tangent.
The straight line in-plane correspondence of described joint face 2 both sides arranges reinforced rib 3, and two reinforced ribs 3 on joint face 2 are symmetrical, and reinforced rib 3 is protruding arc surface, and the height of reinforced rib 3 is 4-6mm.
