  • Patent number: 10207767
    Abstract: Responsive to a hydraulic piston advancing out of a piston housing in a second brake arm and contacting a piston cam surface of a first brake arm, the second brake arm pivots around a second pivot. As this is happening, a cam surface in the second brake arm lifts a contact surface of a first force transfer member of the first brake arm, imparting torque to the first brake arm which then pivots around a first pivot. The cam surface is shaped to impart synchronous motion to the first and second pad holders. Splitting one of the brake arms with a centering member permits a centering adjust feature.

  • Patent number: 9016443
    Abstract: The present invention discloses a method for producing brake drum, wherein three different metallic materials are used for the three-layer construction; and two layers made of different molten metallic materials are cast based upon the prefabricated steel shell (with steel or gray iron for the structural layer and the Mo-containing, abrasion-resistant alloy cast iron for the braking friction layer) so that atoms from these two adjacent but different metallic layers inter-diffuse across the interface to form a solid fusant or an inter-metallic compound, thereby generating a very strong metallurgical bond. The present invention also provides a brake drum, comprising a brake drum shell, a structural layer inside the brake drum shell, and a friction layer inside the brake drum structural layer and for braking.

    Abstract: Provided is a vehicle speed control device with respect to which the speed at which a centrifugal brake operates can be easily changed from the outside without disassembling the device. A brake drum 11 is fixed to a vehicle body 101a. A brake shoe 23 rotates around a rotary shaft 20 of the wheel 101c, and reduces the rotation speed of the wheel 101c as a result of coming into contact with an inner circumferential side face of the brake drum 11. A spring 24 prevents contact between the brake drum 11 and the brake shoe 23 when the rotation speed of the wheel 101c is lower than or equal to a predetermined speed, and permits contact between the brake drum 11 and the brake shoe 23 when the rotation speed of the wheel 101c exceeds the predetermined speed. A position change mechanism 25 is installed within the brake drum 11, and changes the position of an end of the spring 24 on one end side.

  • Patent number: 7258209
    Abstract: A brake drum includes a ring-shaped drum body, and a friction member secured to the inner circumferential surface of the drum body. Because the drum body is formed of a lightweight Al alloy and the friction member is formed of an Al-base composite material, the brake drum can be reduced in weight as a whole. Further, because the friction member, having projection portions formed on its outer periphery, is cast enveloped by molten metal of the Al alloy, the friction member and the drum body can be firmly fastened together. Thus, even when a great braking force is applied to the drum brake, the friction member can be prevented from being undesirably detached from the drum body.

  • Patent number: 6962241
    Abstract: A cable disengagement prevention configuration for a drum brake device that provides a simple and safe connection of a brake cable to a brake lever and reliably prevents disengagement of the brake cable after connecting the brake cable to the brake lever. The cable disengagement prevention configuration mainly comprises a bowfront portion (18f) of the brake lever (18) and a brake shoe (11). The bowfront portion (18f) is formed between a primary seating (18e) and a secondary seating (18g) and is positioned apart from the primary seating (18e) at an opening side of a U-shaped groove (18d). The cable disengagement prevention configuration allows a cable end fitting (28) to pass through a gap between the brake lever (18) and the brake shoe (11) only when rotating the brake lever (18).

  • Patent number: 6619441
    Abstract: A brake assembly utilizes a conical brake drum and matching conical brake lining assembly to provide a more efficient braking system. An adjuster mechanism with a pair of conical adjuster members is controlled by an electric motor and worm gear drive. As the lining wears, the adjuster mechanism pulls the conical adjuster members towards one another to force the brake linings outwardly to maintain a predetermined distance between the drum and the brake lining assembly.
