Abstract
The utility model provides a motorcycle sprocket locking structure, wherein the sprocket is connected to a buffer body through bolts and hexagon nuts and is provided with four bolt holes arranged uniformly in circumferential direction; a locking sheet is integrally extended out of the edge of the bolt hole of the sprocket and is close to one side surface of the hexagon nut; every two of four bolt holes on the sprocket form a group; and two bolt holes in the same group are communicated through an arc-shaped hole. The bolts between the sprocket and the buffer body are locked for preventing loosening so as to ensure that the sprocket is reliably connected to the buffer body, thereby improving safety of driving a vehicle.
Description
Technical field
The utility model relates to motorcycle part, especially the chain wheel of motorcycle locking mechanism.
Background technology
Adopt the motor vehicle wheel hub assembly of chain gear mainly to form by sprocket wheel and buffer body; The sprocket wheel bolt together is on buffer body, and buffer body passes through bearing installation again on wheel shaft, and the bearing end is installed oil sealing; Because the lockable mechanism that has no behind the bolt together between sprocket wheel and the buffer body to carry out spacing to bolt; Period of service long afterwards, bolt occurs easily loosening, causes chain releasing even safety misadventure.
The utility model content
The purpose of the utility model provide a kind of can guarantee sprocket wheel more failure-free be connected the chain wheel of motorcycle locking mechanism on the buffer body.
For realizing above-mentioned purpose, the utility model provides a kind of chain wheel of motorcycle locking mechanism, and sprocket wheel is connected on the buffer body through bolt and hexagonal nut; Sprocket wheel is provided with and is four bolts hole of circumferential well-distributed; All-in-one-piece is extended with locking plate at the bolt hole edge of sprocket wheel, and locking plate is posted by one of them side of nut, in four bolts hole on the sprocket wheel; Per two bolts hole are formed one group, and two bolts hole on the same group are connected through the circular arc hole slot.
Because the position corresponding to bolt hole is provided with locking plate on the chain wheel side; A wherein side that assembles the back hexagonal nut abuts on the locking plate; Thereby bolt and hexagonal nut are locked, prevent that hexagonal nut from rotating, reach and avoid bolt loosening problem to occur.
The beneficial effect that the utility model is obtained is: bolt can not occur becoming flexible because of locking, has guaranteed that the sprocket wheel failure-free is connected on the buffer body, has improved the vehicle operating safety.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is that the A of Fig. 1 is to view.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further explain.
Like Fig. 1, shown in Figure 2, the described chain wheel of motorcycle locking mechanism of the utility model, sprocket wheel 1 is connected on the buffer body 4 through bolt 2 and hexagonal nut 3; Sprocket wheel 1 is provided with and is four bolts hole of circumferential well-distributed; All-in-one-piece is extended with locking plate 5 at the bolt hole edge of sprocket wheel 1, and locking plate 5 is posted by one of them side of hexagonal nut 3, in four bolts hole on the sprocket wheel 1; Per two bolts hole are formed one group, and two bolts hole on the same group are connected through circular arc hole slot 6.
Because the position corresponding to bolt hole is provided with locking plate 5 on sprocket wheel 1 side; A wherein side that assembles back hexagonal nut 3 abuts on the locking plate 5; Thereby bolt 2 and hexagonal nut 3 are locked, prevent that hexagonal nut 3 from rotating, reach and avoid bolt 2 loosening problem to occur; Guaranteed that sprocket wheel 1 failure-free is connected on the buffer body 4, has improved the vehicle operating safety.
