Abstract

The invention discloses an engine. The engine comprises a gearshift drum and a shifting fork, wherein a sleeve on the shifting fork is arranged on the gearshift drum in a sleeving manner, a hollowed part is arranged on the gearshift drum, and the hollowed part is arranged on the non-working side of the gearshift drum. As the engine provided by the invention is additionally provided with the hollowed part, and the hollowed part is arranged on the non-working side, the weight of the gearshift drum is greatly reduced, and the product cost is reduced. Moreover, as the weight of the gearshift drum is reduced, correspondingly, the weight of components in the engine is also easily kept balanced, and as a result, the work stability of the engine is also improved.

Description

technical field [0001] The invention relates to the technical field of engines, in particular to an engine. Background technique [0002] The weight of the transmission drum in the traditional motorcycle engine is generally all heavy, causing the weight in the engine to easily exceed the balance range, the engine is unstable, and there is a serious waste of materials, and the cost of the product is also high. Contents of the invention [0003] In view of this, the purpose of the present invention is to provide an engine, which greatly reduces the weight, reduces the product cost, and relatively further improves the stability of the engine operation. [0004] In order to solve the above technical problems, the present invention provides an engine, including a transmission drum and a shift fork, the sleeve on the shift fork is sleeved on the transmission drum, and the transmission drum is provided with a hollow part, the hollow part is set on the non-working surface of the ...
