  • Patent number: 7258207
    Abstract: An automatic shoe clearance adjustment apparatus having a ratchet wheel 124b and a driving member 127 comprising a pawl section 127f making a ratchet engagement with the ratchet wheel 124b and an arcuate leaf spring section 127e developing a resilient force for adjusting the automatic shoe clearance adjustment apparatus. The leaf spring section 127e is made of bi-metal. When the temperature of the leaf spring section 127e exceeds the predetermined degree, the arcuate leaf spring section 127e thermo-deflects so as to weaken the resilient force, thereby the automatic shoe clearance adjusting operation is suspended.

  • Patent number: 6817450
    Abstract: A brake cable connecting apparatus ensures prevention of brake cable disengagement by a simple structure that offers simple and accurate assemblability. The brake cable connecting apparatus comprises the strut 23 engaging with the brake shoe 12 and the plate-like brake lever engaging with the brake shoe 13. The proximal portion 24a of the brake lever 24 is pivotally positioned in the wider space 23c formed between the two facing surface walls of the strut 23. The cable end 42 of the brake cable 40 is connected with the free end 24e of the brake lever 24 by the connecting pin 43. The inner cable 41 is operated to effectuate braking, and the projection 24g of the free end 24e interferes with the resilient stopper 33 of the resilient member 30 mounted on the strut 23 and is positioned on the rotating trajection of the brake lever 24.

  • Patent number: 6508339
    Abstract: A shoe clearance over-adjustment prevention apparatus employable to various types of automatic shoe clearance adjustment devices and drum brakes and designable to have a common thermo-sensitive member suitable for mass production. The thermo-sensitive member 60 is sandwiched between the strut 20 and the brake lever 30 to cause a functional engagement, and if the brake temperature reaches a predetermined value or range, the strut 20 is pushed toward the brake shoe 12 so as to disable the automatic shoe clearance adjustment operation.

  • Patent number: 6328141
    Abstract: A adjustment lever (80) has dual-functions characterized in that when an actuating force to a brake shoe (20) to move outward reaches predetermined magnitude, a device (80g) prevents over-adjustment of shoe-to-drum clearances disables a device (70) to restrict return positions of brake shoes inhibiting the brake shoes movement in the direction to separate each other and when a brake temperature rises certain degree, a device (80d) to prevent over-adjustment of brake shoe-to-drum clearances disables the device (70) to restrict return position inhibiting the brake shoe movement as well.
