The problem of big, low intensity is deformed at central axis hole.
The technical solution adopted for the present invention to solve the technical problems is：
A kind of Motorcycle Engine Shell, including shell body and the driving side body that is adapted to therewith, shell body and driving side
Housing is made of aluminium alloy, and driving side body is provided with crankshaft hole and countershaft hole, the driving of crankshaft hole and countershaft hole outer rim
The inboard convex set for being provided with the figure of eight of side body, the driving side shell rim are provided with the tank wall to form a circle, convex set and tank wall it
Between be provided with a plurality of first gusset；Driving side body corresponding to the crankshaft hole on the outside of convex set is provided with the first axis hole, first axle
Hole outer is provided with covers the first bulge loop being connected as a single entity with convex, and a plurality of first auxiliary muscle is provided between the first bulge loop outer ring and tank wall；Institute
State and be provided with a boss on the inside of the outer side box wall of convex set corresponding to countershaft hole, boss is provided with the second axis hole, and the second axis hole outer is provided with
Second bulge loop, a circular intermediate mass is provided between boss and convex set, intermediate mass is connected as a single entity with convex set, and intermediate mass and tank wall
The second auxiliary muscle is equipped between boss.
The tank wall end face is provided with the locating slot of adaptation corresponding with the special-shaped raised line of shell body end face.
The tank wall outer ring is provided with multiple engaging lugs for fixing shell body, and engaging lug is provided with and shell body side
Screwed hole corresponding to the mounting hole of edge.
Convex set, the first bulge loop and the convex edge of table are set to round-corner transition.
The driving side body is formed using aluminium alloy compression casting, the crankshaft hole, the axis hole of countershaft hole first and the second axis hole
Set on semi-finished product after die casting.
The beneficial effects of the invention are as follows：Pass through the setting of convex set, the first bulge loop and boss, crankshaft hole, countershaft hole, first axle
Driving side casing rigidity at hole and the second axis hole is higher, and thermal deformation at work is smaller, reduces to correspond to therewith respectively and matches somebody with somebody
The relative displacement of the axle of conjunction, it greatly reducing abrasion, reduce noise；It is and auxiliary by the first gusset, the first auxiliary muscle and second
The setting of muscle, it can further increase the structural strength and stability of convex set, the first bulge loop and boss again, make engine operation more
Add steadily, vibrations are smaller.
Brief description of the drawings
The present invention will be further described with reference to the accompanying drawings and examples.
Fig. 1 is the perspective view structural representation of the present invention.
Embodiment
Reference picture 1, a kind of Motorcycle Engine Shell of the invention, including shell body and the driving side body being adapted to therewith
