Embodiment Construction

[0009] Such as figure 1 As shown, the present invention provides the right crankcase of motorcycle engine, comprises box body 1, and box body 1 is connected with motorcycle engine right crankcase cover, and box body 1 is aluminum alloy die-casting, and the wall of box body 1 The thickness is 4 mm, the side of the box body 1 is provided with reinforcing ribs 2 , and the box body 1 is provided with fastening screw holes 3 .

[0010] In this embodiment, the box body 1 is an aluminum alloy die-casting, the material used is aluminum alloy, and its density is 2.7g / cm 3 , while the density of cast iron is 7.8g / cm 3 , In this way, the weight of die-casting products is only about 34.6% of the weight of existing casting products, which can meet the development needs of light weight. In fact, the wall thickness of the die-casting product is only 4mm, while the wall thickness of the original casting product is 6mm, which provides good conditions for the design of the fastening screw hol...

Abstract

The invention belongs to the technical field of engines, and particularly relates to a motorcycle engine right bent axle box which comprises a box body. The box body is connected with a motorcycle engine right bent axle box cover. The box body is an aluminum alloy casting piece. The wall thickness of the box body is 4 mm. A reinforced rib is arranged on the side face of the box body. The multiple problems that an existing motorcycle engine right bent axle box is not reasonable in structural design so that product wall thickness is large, a product is heavy, fastening hole design is complex and the like are solved.

Description

technical field [0001] The invention belongs to the technical field of engines, and in particular relates to a right crankcase of a motorcycle engine. Background technique [0002] At present, most of the right crankcases of motorcycle engines are casted with cast iron materials. Not only the product has a large wall thickness and is heavy, it cannot be assembled into a motorcycle to meet the development needs of light weight; and when the fastening hole is designed, The steps need to be cast first, and can only be used after drilling and tapping, which greatly reduces the work efficiency and increases the production cost of the enterprise, which is very unfavorable for the long-term development and progress of the enterprise. Contents of the invention [0003] Purpose of the present invention: In order to solve many problems such as large product wall thickness, heavy product and troublesome fastening hole design caused by unreasonable structure design of the existing mot...
