The front side of the rear wheel hub body is distributed with screw holes, bolt holes, half shaft holes and weight reduction grooves; one side of the rear wheel hub body is provided with a brake disc and a flange surface, the other side of the rear wheel hub body is provided with a screw assembling hole and a reinforcing rib, and the middle of the rear wheel hub body is provided with a duplex bearing hole and an oil seal groove. By adopting the technical scheme, the brake disc is arranged on the rear wheel hub to replace a brake drum, so that the weight can be effectively reduced, the production cost is reduced, the torque force generated by the brake disc in a brake system is consistent with the power generated by friction, and the operation safety coefficient of the automobile is improved.
Description
Technical Field
The utility model relates to the automobile parts field is a wheel hub behind disc brake.
Background
In the braking system of the automobile, the braking system is jointly completed by a brake drum, a hub and a brake shoe, the rear hub is positioned at the end part of a transmission shaft and is an important part for connecting a half shaft flange, the brake drum and a wheel disc assembly, and the important part has the function of transmitting torque, so that the automobile obtains forward power and supports the rear wheel of the automobile, and the balance force and the operability of the automobile are ensured. But the problems existing at present are that: firstly, the brake drum is heavy and has high manufacturing cost; secondly, the torque force generated by the brake drum during braking is inconsistent with the power generated by friction; thirdly, the weight of the automobile is increased in the braking system, the production cost is increased, and the fuel consumption is large.
Disclosure of Invention
The utility model aims at providing a wheel hub behind disc brake.
The utility model discloses a realize like this: a disc brake rear wheel hub is characterized in that screw holes, bolt holes, half shaft holes and weight reduction grooves are distributed on the front surface of a rear wheel hub body; one side of the rear wheel hub body is provided with a brake disc and a flange surface, the other side of the rear wheel hub body is provided with a screw assembling hole and a reinforcing rib, and the middle of the rear wheel hub body is provided with a duplex bearing hole and an oil seal groove.
The screw holes are ten and are uniformly distributed.
Ten bolt holes are uniformly distributed.
The number of the weight reduction grooves is five, and the weight reduction grooves are uniformly distributed.
By adopting the technical scheme, the brake disc is arranged on the rear wheel hub to replace a brake drum, so that the weight can be effectively reduced, the production cost is reduced, the torque force generated by the brake disc in a brake system is consistent with the power generated by friction, and the operation safety coefficient of the automobile is improved.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is a schematic diagram of a right-side view cross-sectional structure of the present invention.
In the figure, 1, screw holes; 2. bolt holes; 3. an oil seal groove; 4. a screw mounting hole; 5. a duplex bearing bore; 6. reinforcing ribs; 7. a flange face; 8. a brake disc; 9. a rear hub body; 10. a weight reduction groove; 11. half shaft hole.
Detailed Description
The present invention will be further explained with reference to the drawings and examples.
In fig. 1 and 2, a screw hole 1, a bolt hole 2, a half shaft hole 11 and a lightening slot 10 are distributed on the front surface of the rear hub body 9; one side of the rear hub body is provided with a brake disc 8 and a flange surface 7, the other side of the rear hub body 9 is provided with a screw assembling hole 4 and a reinforcing rib 6, and the middle of the rear hub body 9 is provided with a duplex bearing hole 5 and an oil seal groove 3.
Ten screw holes 1 are uniformly distributed.
Ten bolt holes 2 are uniformly distributed. The torque force generated by the brake drum during braking is consistent with the power generated by friction, and the running safety factor of the automobile is improved.
Five weight-reducing grooves 10 are uniformly distributed. Due to the weight reduction grooves 10, the rear wheel hub is reduced in weight, and fuel consumption is correspondingly reduced in operation.
When in use, the disc type rear wheel hub is only required to be connected to the brake disc 8 through bolts. In the assembling process, the assembling efficiency can be improved, and the cost can be reduced.
Claims (4)
