Abstract
A buffer body assembly for large-displacement motorcycle transmission is provided with a buffer body, wherein one end of the buffer body is sleeved with a chain wheel, and the chain wheel is fixedly connected with the buffer body through a countersunk head bolt; at least two bearings are arranged in the middle of the buffer body; the other end of the buffer body is provided with a toothed claw, and the toothed claw is provided with a notch. The utility model discloses a change the atress structure of the buffering body, turn the great variety into simple, the life of mould has prolonged, and product surface quality, inside quality increase substantially, and the obvious improvement of production efficiency has saved raw and other materials 23%, and the destructive power has improved 70%. The 8.8-grade stud in the prior art is changed into a 10.9-grade countersunk head bolt, the stud is easy to loosen in the using process, the centering and the positioning of the countersunk head bolt are obviously superior to those of a common bolt, and the shearing force is greatly improved. The countersunk head bolt also adopts a fashionable element of an inner plum blossom hexagon, and the attractiveness is improved.
Description
Technical Field
The utility model relates to a technical field is made to the motorcycle, concretely relates to big discharge capacity motorcycle transmission is with buffering body subassembly.
Background
With the improvement of the living standard of people, the motorcycle with large discharge capacity gradually enters the blowout era. In the prior art, a small-displacement buffer body assembly is basically used, so that bolts are easy to loosen when a motorcycle runs at a high speed, and even a buffer body and a bearing are damaged; or the buffer body is heavy in design and complex in structure, so that resource waste is caused, and the buffer body is easily damaged due to a plurality of air holes in the internal structure.
SUMMERY OF THE UTILITY MODEL
The utility model discloses to prior art's not enough, provide the transmission of big discharge capacity motorcycle and use buffering body subassembly, concrete technical scheme is as follows:
the buffer body assembly for the transmission of the large-displacement motorcycle is provided with a buffer body (1), one end of the buffer body (1) is sleeved with a chain wheel (2), and the chain wheel (2) is fixedly connected with the buffer body (1) through a countersunk head bolt;
at least two bearings (3) are arranged in the middle of the buffer body (1);
the other end of the buffer body (1) is provided with a toothed claw (4), and the toothed claw (4) is provided with a notch (5).
As an optimization: the countersunk head bolt is a 10.9-grade countersunk head inner hexagon bolt. Stud bolts adopted in the prior art are easy to loosen in the using process, centering and positioning of countersunk head bolts are obviously superior to those of common bolts, and shearing force is greatly improved. The countersunk head bolt also adopts a fashionable element of an inner plum blossom hexagon, and the attractiveness is improved.
As an optimization: the notch (5) is of a U-shaped structure. The die-casting mould is easy to demould during die-casting, the appearance quality and the service life of the mould are improved, the material is saved, the appearance is attractive, and the use is not influenced.
As an optimization: the middle part of the buffer body (1) is provided with a bearing installation cylinder (6), the inner wall of the bearing installation cylinder (6) is provided with the bearing (3), and the outer wall of the bearing installation cylinder (6) is fixedly connected with the buffer body (1) through at least three connecting strips (7).
The utility model has the advantages that:
1. by changing the stress structure of the buffer body, the process is simplified, the service life of the die is prolonged, the surface quality and the internal quality of the product are greatly improved, the production efficiency is obviously improved, the raw materials are saved by 23 percent, and the destructive power is improved by 70 percent.
2. The 8.8-grade stud in the prior art is changed into a 10.9-grade countersunk head bolt, the stud is easy to loosen in the using process, the centering and the positioning of the countersunk head bolt are obviously superior to those of a common bolt, and the shearing force is greatly improved. The countersunk head bolt also adopts a fashionable element of an inner plum blossom hexagon, and the attractiveness is improved.
3. Through increasing the bearing and using duplex bearing, prolonged life, the atress is effectual, makes the motorcycle operation more steady.
4. The claw part of the buffer body is provided with a notch, so that the die is easy to demould during die casting, the appearance quality and the service life of the die are improved, the material is saved, the appearance is attractive, and the use is not influenced.
5. The pitch of the bolt holes is increased, and the stressed torque is greatly enhanced.
