Abstract
The utility model discloses chain stay after a kind of heavier-duty cross-country motorcycle, include the connecting panel of symmetrically arranged two chain stays supervisor and connection two chain stays supervisors, described chain stay supervisor is welded by two seamless tubes, two seamless tubes are quadrangle after bending, welding, and the inner side of described two chain stays supervisor is also welded with the brace panel of form fit.By combination after two seamless tube bendings to be welded into the chain stay supervisor of rear chain stay in quadrangle, bottom fork structure steadiness after greatly improving, decomposes the power that all directions are subject to, better to adapt to the environment for use of cross-country motorcycle; The brace panel of two chain stay supervisor inner side welding strengthens the structural strength of rear chain stay further, ensures that chain stay supervisor also can not be out of shape after a long time use, firmly durable.
Description
Technical field
The utility model relates to chain stay after a kind of heavier-duty cross-country motorcycle.
Background technology
Motorcycle rear fork is one of vitals of motor bike, and it is primarily of left and right chain stay supervisor and the connecting panel composition being connected left and right chain stay supervisor.Rear chain stay is positioned at the middle and lower part of motor bike, is generally " H " shape, is arranged between the vehicle frame of motor bike and wheel shaft, plays support and connection function.Existing motorcycle rear fork is because cost reason is generally directly designed to single hose chain stay supervisor, this design weak point has two: 1, the pressure that bears of single tube is uneven, can not decompose the impulsive force of each side produced because of motion from motor bike well; 2, the welding stress of single hose chain stay supervisor is concentrated, and to the precision of rear chain stay size and the service life of rear chain stay, all has a certain impact.The rear chain stay of this structure is applied on cross-country motorcycle, and using state is poorer, and therefore, existing rear chain stay haves much room for improvement.
Utility model content
In order to overcome the deficiencies in the prior art, the utility model provides chain stay after a kind of heavier-duty cross-country motorcycle, can the power of efficient-decomposition all directions, firmly durable.
The utility model solves the technical scheme that its technical matters adopts:
Chain stay after a kind of heavier-duty cross-country motorcycle, include the connecting panel of symmetrically arranged two chain stays supervisor and connection two chain stays supervisors, described chain stay supervisor is welded by two seamless tubes, two seamless tubes are quadrangle after bending, welding, and the inner side of described two chain stays supervisor is also welded with the brace panel of form fit.
As the improvement of technique scheme, between two seamless tubes of described chain stay supervisor, be welded with support tube.
As the further improvement of technique scheme, one end of described chain stay supervisor connecting vehicle frame is provided with bearing carrier ring.
Further, described two chain stays supervisor is provided with the transverse tube for connecting damping spring near the position of bearing carrier ring.
Further, four angles of described connecting panel extend to form floor.
Further, described connecting panel is upper and lower two layers.
The beneficial effects of the utility model are: be responsible for by chain stay combination after two seamless tube bendings welded again as rear chain stay in quadrangle, bottom fork structure steadiness after greatly improving, decompose the power that all directions are subject to better, to adapt to the environment for use of cross-country motorcycle; The brace panel of two chain stay supervisor inner side welding strengthens the structural strength of rear chain stay further, ensures that chain stay supervisor also can not be out of shape after a long time use, firmly durable.Eliminate existing motorcycle rear fork because use single hose chain stay supervisor, and the chain stay brought is responsible for the uneven and dimensional accuracy of the pressure born, service life poor defect.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Fig. 1 is the left view that the utility model uses;
Fig. 2 is birds-eye view of the present utility model.
Detailed description of the invention
With reference to Fig. 1 ~ Fig. 2, chain stay after a kind of heavier-duty cross-country motorcycle, include symmetrically arranged two chain stays supervisor 1 and connect the connecting panel 2 that two chain stays are responsible for 1, described chain stay supervisor 1 is welded by two seamless tubes, two seamless tubes are quadrangle after bending, welding, and the inner side of described two chain stays supervisor 1 is also welded with the brace panel 3 of form fit.Adopt said structure, be welded into the chain stay supervisor 1 of rear chain stay again in quadrangle by two seamless tube combinations, bottom fork structure steadiness after greatly improving, decomposes the power that all directions are subject to, better to adapt to the environment for use of cross-country motorcycle; Inside two chain stay supervisors 1, the brace panel 3 of welding strengthens the structural strength of rear chain stay further, ensures that chain stay supervisor 1 also can not be out of shape after a long time use, firmly durable.
In the present embodiment, preferably, support tube 101 is welded with between two seamless tubes of described chain stay supervisor 1.Adopt said structure, support tube 101 ensures that the shape of the quadrangle of two seamless tube compositions of chain stay supervisor 1 is firm, not yielding.
In the present embodiment, preferably, one end that described chain stay is responsible for 1 connecting vehicle frame is provided with bearing carrier ring 102.Adopt said structure, rear chain stay is connected by bearing with vehicle frame, rotates more smooth and easy.
In the present embodiment, preferably, described two chain stays supervisor 1 is provided with the transverse tube 103 for connecting damping spring near the position of bearing carrier ring 102.Adopt said structure, rear chain stay adopts the central damping of single armed, is more suitable for land locomotion; Transverse tube 103 can also strengthen the structural strength of rear chain stay.
In the present embodiment, preferably, four angles of described connecting panel 2 extend to form floor.Adopt said structure, the floor that four angles of connecting panel 2 extend to form adds structural soundness, and profile is also more attractive in appearance.
In the present embodiment, preferably, described connecting panel 2 is upper and lower two layers.Adopt said structure, the stressed of connecting panel 2 more balances, and structure is more firm.
The above, just better embodiment of the present utility model, but the utility model is not limited to above-described embodiment, as long as it reaches technique effect of the present utility model with any same or similar means, all should fall within protection domain of the present utility model.
