  • Patent number: 9010502
    Abstract: A retaining formation defined on a brake lever of an air disc brake includes a push fit/snap fit connection for releasably securing a push rod to a brake lever. The retaining formation can include a pinned connection and a ball and socket joint, and a main axis of the pinned connection is coincident with a center of rotation of the ball and socket joint. The retaining formation can include a concave formation on one of the push rod and the brake lever and a corresponding convex formation on the other of the push rod and the brake lever. The concave formation at least partially surrounds the convex formation to prevent axial separation of the push rod and the brake lever. A method of assembling a brake subassembly includes the steps of assembling a push rod and a brake lever including a retaining formation such that at least a portion of the retaining formation deforms during assembly and resiles when the push rod is assembled to the brake lever to provide a snap fit connection therebetween.

  • Patent number: 8246010
    Abstract: A fluid shear actuated brake mechanism includes an outer hub secured to a hoist frame, a main brake disc stack engaged between the outer hub and a hoist drum shaft, an actuator hub helically engaged with the outer hub, and an actuator disc stack engaged between the actuator hub and the shaft. The main disc stack and the actuator disc stack are immersed in a fluid. Rotation of the shaft in a load lowering direction generates fluid shear in the actuator disc stack which rotates the actuator hub in a lowering direction and advances it toward the main disc stack, compressing it and the actuator disc stack. Rotation of the shaft in an opposite load lift direction retract the actuator hub from the main disc stack.

  • Patent number: 6223867
    Abstract: A disk pass portion for receiving a part of a disk is provided between a cylinder portion and an outer claw portion of a caliper body at the inner peripheral side of a bridge portion of the caliper body. A pair of mounting portions extend arcuately from both sides of the bridge portion to lie outside the disk pass portion with respect to the radial direction of the disk. A pair of sliding pins are secured to the distal ends of the mounting portions through pin bolts and slidably fitted in pin-fitting holes provided in a mounting member supporting the caliper. When the brake is activated, friction pads are pressed against the disk by the caliper. At this time, deformation of the caliper by reaction forces from the disk is small around the area where proximal portions of the mounting portions are connected to the caliper body.
