Abstract

In one embodiment, a disc brake assembly for use with a rotor includes a parking disc brake and a pair of service disc brakes. The parking disc brake is provided between the two service disc brakes, the parking and service disc brakes being disposable in a circumferential direction along the rotor. At least one component part of at least one service disc brake is used as a torque-receiving part of the parking disc brake. In another embodiment, the torque-receiving part is a caliper. In another embodiment, the torque-receiving part is a carrier. In yet another embodiment, the hydraulic type service disc brake is a floating-caliper type. In still another alternate embodiment, at least one tightening part is shared to install the adjacent side of the service disc and the parking disc brake on a stationary part of a vehicle.

Claims

1. A disc brake assembly, comprising:

two hydraulic type disc brakes for a service brake that are disposable in a circumferential direction along a disc rotor and operable to activate a braking effect by pressing against opposite sides of the disc rotor; and

a mechanical floating-caliper type disc brake for a parking brake, said mechanical floating-caliper type parking disc brake being provided between the two hydraulic type disc brakes, wherein at least one component part of said two hydraulic type service disc brakes is used as a torque-receiving part of said mechanical floating-caliper type parking disc brake.

2. The disc brake assembly of claim 1 wherein said hydraulic type service disc brake is a fixed-caliper type.

3. The disc brake assembly of claim 1 wherein said torque-receiving part is a caliper.

4. The disc brake assembly of claim 1 wherein said hydraulic type service disc brake is a floating-caliper type.

5. The disc brake assembly of claim 1 wherein said torque-receiving part is a carrier.

6. The disc brake assembly of claim 1 wherein a tightening part that installs said mechanical floating-caliper type parking disc brake on a stationary part and is shared to also fix at least one hydraulic type service disc brake on the stationary part.

7. The disc brake assembly of claim 1 wherein said mechanical floating-caliper type parking disc brake comprises a spring chamber operating mechanism.

8. The disc brake assembly of claim 2 wherein said mechanical floating-caliper type parking disc brake comprises a spring chamber operating mechanism.

9. The disc brake assembly of claim 3 wherein said mechanical floating-caliper type parking disc brake comprises a spring chamber operating mechanism.

10. The disc brake assembly of claim 4 wherein said mechanical floating-caliper type parking disc brake comprises a spring chamber operating mechanism.

11. The disc brake assembly of claim 5 wherein said mechanical floating-caliper type parking disc brake comprises a spring chamber operating mechanism.

12. A disc brake assembly for use with a rotor, comprising:

a pair of service disc brakes circumferentially positionable along the rotor; and

a mechanical floating-caliper parking disc brake disposed between the service disc brakes, wherein at least one component part of at least one service disc brake is also used as a torque-receiving part of the parking disc brake.

13. The disc brake assembly of claim 12 wherein at least one service disc brake is a fixed-caliper type disc brake.

14. The disc brake assembly of claim 12 wherein at least one service disc brake is a floating-caliper type disc brake.

15. The disc brake assembly of claim 12 wherein said mechanical floating-caliper type disc brake comprises a spring chamber operating mechanism.

16. The disc brake assembly of claim 12 wherein said torque-receiving part is a caliper.

17. The disc brake assembly of claim 12 wherein said torque-receiving part is a carrier.

18. The disc brake assembly of claim 12 wherein a tightening part coupled to the parking disc brake and attachable to a stationary part of a vehicle, and is also coupled to at least one hydraulic type service disc brake on the stationary part.
