Abstract
The utility model relates to a tooth disc locking ring of a back wheel of a motorcycle, which is composed of a circular table-shaped body and a cylindrical body, wherein the inner parts of the circular table-shaped body and the cylindrical body are uniformly hollow, the outer side surface of the circular table-shaped body forms a rotative surface inward from top to bottom, and the rotative surface transits to the cylindrical body. The hollow diameter of the inner part of the circular table-shaped body is smaller than the hollow diameter of the inner part of the cylindrical body, the circular table-shaped body and the hollow part of the inner part of the cylindrical body are communicated by a shaft hole, and the diameter of the shaft hole is smaller than the hollow diameter of the inner part of the circular table-shaped body. The utility model has the advantages of simple structure, convenient assembly and safety.
Description
Technical field
The utility model relates to the annex that uses on a kind of motor bike, particularly relates to a kind of motor cycle rear wheel chain wheel and pins circle.
Background technology
At present, the installation in the prior art between motor cycle rear wheel wheel hub and the chain wheel is realized by snap ring, promptly utilizes snap ring that chain wheel is pinned on wheel hub.By this way after the motorcycle driving stretch journey of stationary hub and chain wheel, under the effect of impact of chain wheel, annular groove enlarges virtually outward, produce bigger endplay immediately between wheel hub and the chain wheel gradually, the oscillating quantity of chain wheel is increased, come the antibacklash words if in time take the mode of cushioning, also can prolong one section use receives a mandate, but motor bike continues to travel and must also can produce endplay between wheel hub and the chain wheel, in the process that cushioning is repaired so repeatedly, because the edge thickness of annular groove is limited, so will inevitably cause snap ring thoroughly to come off, fixing chain wheel, and snap ring has at last arrived certain limit, and coming off suddenly of snap ring can cause serious consequence in the middle of the motorcycle driving.
Summary of the invention
The purpose of this utility model is to remedy the deficiencies in the prior art, pins circle for people provide a kind of simple in structure, safe and reliable motor cycle rear wheel chain wheel.
The purpose of this utility model is achieved through the following technical solutions.
Motor cycle rear wheel chain wheel of the present utility model pins circle, include the round platform body and the cylinder that are hollow by inside, and be one, the external side of truncated cone-shaped inwardly forms the surface of revolution from top to bottom and carries out the transition to cylinder, round platform body inner hollow diameter is less than cylinder inner hollow diameter, and the round platform body is connected with axis hole with cylinder inner hollow part, and the diameter of axis hole is less than round platform body inner hollow diameter.
That the utility model has is simple in structure, easy to assembly, use the advantage such as long, safe and reliable of receiving a mandate.
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the A-A section-drawing of Fig. 1.
Fig. 3 is a running condition scheme drawing of the present utility model.
The specific embodiment
As shown in Figure 1 and Figure 2, motor cycle rear wheel chain wheel of the present utility model pins circle, the round platform body 1 and the cylinder 2 that are hollow by inside constitute, and be one, round platform body 1 lateral surface inwardly forms the surface of revolution 3 from top to bottom and carries out the transition to cylinder 2, round platform body 1 inner hollow diameter is less than cylinder 2 inner hollow diameters, and round platform body 1 is connected with axis hole 4 with cylinder 2 inner hollow part, and the diameter of axis hole 4 is less than round platform body 1 inner hollow diameter.
As shown in Figure 3, the utility model is installed on the motorcycle rear axle and uses, be that chain wheel 7 is installed on the wheel hub 8 by wheel hub lining 9 and the bolt 10 that is arranged in the wheel hub 8, by bearing 15 stationary hub 8, the chain wheel that bearing 11 and sleeve 12 are installed in round platform body 1 inner hollow is pinned circle insert the motorcycle rear axle 6 that chain wheel 7 has been housed, again car fork 13 and packing ring 14 are inserted on the hind axle 6, with captive nut 5 fixedly between chain wheel 7 and the wheel hub 8, during motorcycle driving, even chain wheel 7 bump cylinders 2, can not produce endplay between wheel hub 8 and the chain wheel 7 yet, no matter travelling, how long distance is also without any danger, control motorcycle driving safety effectively, also prolonged the service life of tire greatly.
