Abstract
The utility model provides a motorcycle sprocket and buffer body assembly, which comprises a sprocket (1), a buffer body (2), a bearing (3) and an oil seal (4); the sprocket (1) is connected with the buffer body (2) through a bolt (5) and a hexagon nut (7); the bearing (3) is mounted in an inner hole of the buffer body (2); the oil seal (4) is disposed at the bearing (3) end; the buffer body (2) is integrally provided with a limiting block (6); the limiting block (6) passes through a bolt hole on the sprocket (1); one side surface of the hexagon nut (7) leans against the limiting block (6) after the hexagon nut is assembled. The bolt will not be loosened due to locking, so that reliable connection between the sprocket and the buffer body is ensured and the vehicle operating safety is improved.
Description
Technical field
The utility model relates to motorcycle part, especially chain wheel of motorcycle and buffer body assembly.
Background technology
On existing chain gear motor bike; Be connected through screw bolt and nut between sprocket wheel and the buffer body, on wheel shaft, the bearing end is installed oil sealing to buffer body through bearing installation; 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 provides a kind ofly can be guaranteed to be connected failure-free chain wheel of motorcycle and buffer body assembly between sprocket wheel and the buffer body.
For realizing above-mentioned purpose, the utility model provides a kind of motor vehicle wheel hub assembly, comprises sprocket wheel, buffer body, bearing and oil sealing; Be connected with hexagonal nut with bolt between sprocket wheel and the buffer body; Bearing installation is in the endoporus of buffer body, and oil sealing is arranged on the bearing end, and all-in-one-piece is provided with limiting stopper on buffer body; Limiting stopper passes the bolt hole on the sprocket wheel, and a wherein side of assembling back hexagonal nut abuts on the limiting stopper.
Because buffer body is provided with limiting stopper hexagonal nut is carried out rotary spacing, thereby bolt and hexagonal nut are locked, prevent that hexagonal nut from rotating, reach and avoid bolt loosening problem to occur.
Effective effect that the utility model is obtained is: bolt can not occur becoming flexible because of locking, has guaranteed that bonded assembly is reliable between sprocket wheel and 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.
Among the figure: 1. sprocket wheel; 2. buffer body; 3. bearing; 4. oil sealing; 5. bolt; 6. limiting stopper; 7. hexagonal nut.
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, described chain wheel of motorcycle of the utility model and buffer body assembly have sprocket wheel 1, buffer body 2, bearing 3 and oil sealing 4; Be connected with hexagonal nut 7 with bolt 5 between sprocket wheel 1 and the buffer body 2; Bearing 3 is installed on the endoporus of buffer body 2, and oil sealing 4 is arranged on bearing 3 ends, and all-in-one-piece is provided with limiting stopper 6 on buffer body 2; Limiting stopper 6 passes the bolt hole on the sprocket wheel 1, and a wherein side of assembling back hexagonal nut 7 abuts on the limiting stopper 6.
Because buffer body 2 is provided with 6 pairs of hexagonal nuts of limiting stopper 7 and carries out rotary spacing; Thereby bolt 5 and hexagonal nut 7 are locked; Prevent that hexagonal nut 7 from rotating, reach and avoid bolt 5 loosening problem to occur that bolt 5 can not occur becoming flexible because of locking; Guaranteed that bonded assembly is reliable between sprocket wheel 1 and the buffer body 2, improved the vehicle operating safety.
Claims (1)
1. chain wheel of motorcycle and buffer body assembly; Comprise sprocket wheel (1), buffer body (2), bearing (3) and oil sealing (4); Be connected with hexagonal nut (7) with bolt (5) between sprocket wheel (1) and the buffer body (2); Bearing (3) is installed on the endoporus of buffer body (2), and oil sealing (4) is arranged on bearing (3) end, it is characterized in that: go up all-in-one-piece at buffer body (2) and be provided with limiting stopper (6); Limiting stopper (6) passes the bolt hole on the sprocket wheel (1), and a wherein side of assembling back hexagonal nut (7) abuts on the limiting stopper (6).
