Abstract

A suspension device for a small internal combustion engine for a bicycle, the internal combustion engine having a lug with a mounting hole, characterized in that a damper assembly is installed in the mounting hole of the lug, the damper assembly is formed by closely assembling a metal inner sleeve and a metal outer sleeve on an inner and outer cylindrical surfaces of a thick-walled tubular elastic rubber member, respectively, and a connection screw passes through the metal inner sleeve and a support frame fixedly connected to a frame of the bicycle to suspend the internal combustion engine on the support frame.

Description

Device for attaching mini internal-combustion engine on bicycle

The utility model relates to the suspension gear of reciprocation internal combustion engine, and particularly compact internal combustion engine hangs and is installed in suspension gear used on the bicycle.

The small-sized single cylinder combustion engine is owing to its generation reciprocal inertia force in service, so its vibration is more serious.When compact internal combustion engine was used to drive bicycle, its vibration can influence the bicycle single-piece and use.For the vibration that the reduces combustion engine influence to bicycle, be by Shock absorber compact internal combustion engine to be suspended on the cycle frame generally, the not only expensive but also institute of this suspension gear takes up space bigger, is unfavorable for the setting and the installation of combustion engine.

Therefore, the purpose of this utility model provides and a kind of compact internal combustion engine is suspended on device on the bicycle rack, and this apparatus structure is simple, low price, and can play the effect of damped vibration effectively.

The utility model proposes a kind of suspension gear of bicycle use compact internal combustion engine, this combustion engine has the lug that has mounting hole, it is characterized in that, in the mounting hole on the described lug dampening assembly is housed, described dampening assembly is to constitute by closely assemble an inner metal sleeve and metal-coating respectively on the inside and outside circle cylinder of a heavy wall tubulose elastic caoutchouc spare, and attaching screw passes described inner metal sleeve and with the affixed bearing support of cycle frame and combustion engine is suspended on the bearing support.

The elastic caoutchouc spare in the lug mounting hole of packing into also can lay respectively at the both sides of lug mounting hole for two elastic caoutchouc spares.

This suspension gear is simple in structure, and cost is low, and has good damping effect.

Below in conjunction with accompanying drawing embodiment of the present utility model is described further.

Fig. 1 is that compact internal combustion engine hangs the scheme drawing that is installed on the bicycle;

Fig. 2 is that the cuing open of dampening assembly of the compact internal combustion engine suspension gear that the utility model proposes shown scheme drawing;

Fig. 3 is the scheme of installation of the compact internal combustion engine suspension gear that the utility model proposes.

Fig. 4 is another embodiment of the dampening assembly of the compact internal combustion engine suspension gear that the utility model proposes.

Ask for an interview Fig. 1, by this figure as seen, compact internal combustion engine 1 suspension can be installed on the cycle frame by the suspension gear that the utility model proposes.Figure 2 shows that the cuing open of dampening assembly in the suspension gear 3 show scheme drawing, this dampening assembly has the elastic caoutchouc spare 7 that thick-wall elastic caoutchouc is made, on the inside and outside cylinder side face of elastic caoutchouc spare 7, inner metal sleeve 8 and metal-coating 6 are housed closely respectively, as shown in Figure 3, dampening assembly refills in the mounting hole of combustion engine lug 5, lug 5 is positioned at the fork-shaped end of supporting member 4, one screw 9 passes the hole of inner metal sleeve 8 and supporting member 4 fork-shaped terminations, is locked with packing ring 11 and nut 10 again.

Another embodiment of the present utility model is same as the previously described embodiments, sees Fig. 4, and its difference only is to have two dampening assemblies, and inner metal sleeve 8 one external parts rely in mounting hole mutually.Elastic caoutchouc spare 7 is positioned at the both sides of mounting hole.

When combustion engine 1 operation produces vibration, because the shock damping action of elastic caoutchouc spare 7 can reduce the influence of vibration to cycle frame.

Claims

1. A suspension device for a small internal combustion engine for a bicycle. The internal combustion engine has a lug with a mounting hole. The inner and outer cylindrical surfaces of a thick-walled tubular elastic rubber member are tightly assembled with a metal inner sleeve and a metal outer sleeve respectively, and connecting screws pass through the metal inner sleeve and the support frame fixed to the bicycle frame to suspend the internal combustion engine on the on the support stand.

2. The device according to claim 1, wherein there are two shock-absorbing components, and the elastic rubber parts are respectively located on both sides of the lug mounting hole.
