Abstract
A buffer body cooperating with chain wheel of motocycle is made of plastics instead of aluminium alloy by injection. A screw bolt for connecting to chain wheel is inserted in it during injection, greatly increasing reliability. Its advantages are light weight, less loss of drive power and low cost.
Description
The present invention relates to a kind of and the supporting buffer body of chain wheel of motorcycle.
Buffer body present and that chain wheel of motorcycle is supporting is to adopt aluminum alloy materials die casting to form.This buffer body weight is big, and the transmission power loss is big, the processing technology complexity behind the die cast, cost height.
The purpose of this invention is to provide a kind of in light weightly, the transmission power loss is low, does not need back processing after the moulding, and cost is low, the whole buffer body that adopts the plastic material single injection-molded.
Technical scheme of the present invention is: a kind of and supporting buffer body of chain wheel of motorcycle, the whole plastic material that adopts replaces original aluminum alloy materials single injection-molded, and wherein buffer body can adopt polycarbonate engineering plastic or polyester engineering plastic or ABS engineering plastics or engineering plastics such as polyformaldehyde engineering plastics or nylon to make.The bolt that connects with sprocket wheel in buffer body is pre-buried when injection mo(u)lding.
Buffer body of the present invention is to adopt the plastic material single injection-molded can reduce more than 50% with the buffer body phase weight/power ratio of aluminum alloy materials, the transmission power loss also reduces greatly, and need not stay the back stock left for machining, no longer carry out back manufacturing procedures such as car, brill, tapping and can reach requirements for quality, thereby make cost descend 30%.Owing in buffer body, be embedded with the bolt that connects sprocket wheel, make to be difficult between sprocket wheel and the buffer body producing becoming flexible, thereby can improve reliability of service.
Below in conjunction with drawings and Examples the present invention is described in further detail:
Fig. 1 is a structure upward view of the present invention;
Fig. 2 is the cutaway view of Fig. 1 on the A-A face;
Fig. 3 is a structure birds-eye view of the present invention.
Structure of the present invention such as Fig. 1, Fig. 2 and shown in Figure 3, buffer body 1, pre-embedded bolt 2 in the buffer body 1, projection 3 on the buffer body 1 (square or circular), wherein buffer body 1 can adopt plastic material such as polycarbonate engineering plastic or polyester engineering plastic or ABS engineering plastics or engineering plastics single injection-moldeds such as polyformaldehyde engineering plastics or nylon.
The working process of this buffer body: the sprocket wheel of motor bike combines as a whole by the pre-embedded bolt in the buffer body 12, chain wheel driving power is passed to buffer body 1, buffer body 1 is passed to wheel hub with power after by the yielding rubber block buffering in 3 drive hubs of the projection on it, and drive wheels is rotated.
