Between be equipped with a plurality of first gusset；Driving side body on the outside of the corresponding convex set of the crankshaft hole is equipped with the first axis hole, first axle
Hole outer is equipped with the first bulge loop being linked together with convex set, and a plurality of first assistant reinforcement is equipped between the first bulge loop outer ring and tank wall；Institute
It states and is equipped with a boss on the inside of the outer side box wall of the corresponding convex set in countershaft hole, boss is equipped with the second axis hole, and the second axis hole outer is equipped with
Second bulge loop is equipped with a circular intermediate mass between boss and convex set, intermediate mass is linked together with convex set, and intermediate mass and tank wall
The second assistant reinforcement is equipped between boss.
The tank wall end face is equipped with the locating slot of adaptation corresponding with the special-shaped raised line of outer housing end face.
The tank wall outer ring is equipped with multiple engaging lugs for fixing shell body, and engaging lug is equipped with and outer housing side
The corresponding threaded hole of mounting hole of edge.
The convex set, the first bulge loop and convex edge of table are set as round-corner transition.
The driving side body is formed using aluminium alloy compression casting, the crankshaft hole, the first axis hole of countershaft hole and the second axis hole
It is arranged on semi-finished product after die casting.
The utility model has the beneficial effects that：Pass through the setting of convex set, the first bulge loop and boss, crankshaft hole, countershaft hole, the
Driving side casing rigidity higher at one axis hole and the second axis hole, thermal deformation smaller at work, it is right therewith respectively to reduce
The relative displacement for the axis that should coordinate greatly reduced abrasion, reduce noise；And pass through the first gusset, the first assistant reinforcement and
The setting of two assistant reinforcements, and the structural strength and stability of convex set, the first bulge loop and boss can be further increased, so that engine is transported
Make more steady, vibrations smaller.
Description of the drawings
The utility model is described further with reference to the accompanying drawings and examples.
Fig. 1 is the perspective view structural schematic diagram of the utility model.
Specific implementation mode
Referring to Fig.1, a kind of Motorcycle Engine Shell of the utility model, including outer housing and the driving side that is adapted to therewith
Shell 1, outer housing and driving side body 1 are all made of aluminium alloy and are made, and driving side body 1 is equipped with crankshaft hole 2 and countershaft hole 3,
The inboard convex set 4 for being equipped with the figure of eight of driving side body 1 of 3 outer rim of crankshaft hole 2 and countershaft hole, when processing, first by convex set 4 with drive
Dynamic side body 1 is whole to be integrally formed, then outputs crankshaft hole 2 and countershaft hole 3 on convex set 4, and 1 edge of driving side body is equipped with
The tank wall 5 to form a circle is equipped with a plurality of first gusset 6 between convex set 4 and tank wall 5；Corresponding 4 outside of convex set of the crankshaft hole 2
Driving side body 1 be equipped with the first axis hole 7,7 outer of the first axis hole be equipped with convex 4 the first bulge loops 8 for being linked together of set, first
A plurality of first assistant reinforcement 9 is equipped between 8 outer ring of bulge loop and tank wall 5；4 outer side box wall of the corresponding convex set in countershaft hole 3,5 inside is equipped with
One boss 10, boss 10 be equipped with the second axis hole 11,11 outer of the second axis hole be equipped with the second bulge loop 12, boss 10 with it is convex set 4 it
