Abstract: A brake wear indicator to provide visual and tactile indication of unacceptable brake wear. The brake wear indicator has a hub drive attached to a cam shaft, a brake wear disk attached to the hub drive and a body attached to a slack adjuster lever. The brake wear disk has a wear detector lug. The body has two the travel limit lugs which extend towards the centerline of the brake wear disk and are on the end of flexible fingers. When the brake linings are approaching unacceptable wear, the wear detector lug contacts one of the travel limit lugs and pushes the travel limit lug and the end of the corresponding finger away from the adjacent outer surface of the body. The rising of the end of the finger above the adjacent surface provides visual and tactile indication of unacceptable brake wear.

Abstract: It is an object of this invention to provide a drum brake device which solves a problem of decreasing the strength of a back plate near an anchor block and reduces potential damage to the parking brake cable. A pivot lever 60 is pivotally mounted on one brake shoe 20. Upper and lower portions of the pivot lever functionally engage with the other brake shoe 30 via struts 81, 70. A parking brake actuator 90 which pivotally supports on the upper strut 81 and activates upon an activation of a parking brake is arranged to be adjacent to a service brake actuator which activates upon an activation of a service brake. Preferably an operational part of the parking brake actuator is projected out from the brake back plate.

Abstract: An anti-theft latch is proposed. The anti-theft latch has a movable stud having a driven means therein. A pin serves to connect the movable stud with the driven means. The driven means is pivotally installed with a static latch. A guide groove is formed on the static latch. The pin is matched with the guide groove. The guide groove of the static latch is formed with a buckling portion. When the movable stud is to be unlocked by an outer force, the pin will eject and buckle the buckling portion so that the static latch can not retract to the movable stud to achieve an effect of statically locking. An auxiliary spring is further installed for pushing the driven means to move forwards. Therefore, in a normal condition, the static latch will achieve an effect of statically locking. As a result, the thief has no possibility to unlock the movable stud to move inwards and therefore, a preferred anti-theft effect is achieved.

Abstract: A dual volume air spring for a truck suspension, which has an air bag chamber providing a variable volume and a fixed volume chamber. The chambers are interconnected by a closable orifice. The air bag is provided with a post-like orifice closer which is pushed into the orifice when the air bag is sufficiently compressed ad withdrawn from the orifice when the air bag is not compressed. In normal operation the orifice is open and the combined volumes of the chambers are available resulting in a low spring rate. The orifice closer has an orifice closing portion which is relatively pliant and a rigid or semi-rigid portion which acts as a bump-stop when the pliant portion is substantially completely compressed. When the orifice is completely closed the spring has a high spring rate.

Abstract: An improved trailer coupling with integral brake actuator that employs sturdier telescoping inner and outer casings and adjustable rollers there between to compensate for wear and tear tolerances over time. The outer casing is a hollow tubular outer beam, and the inner case is formed as a section of hollow I-beam adapted for a telescoping fit inside the outer case. A plurality of rollers are secured to each side of the outer case and project inwardly to provide bearing support against the outwardly-projecting lateral ridges of the I-beam, and this results in a substantially frictionless telescoping extension. Each roller is selectably offset on an axle to allow adjustment of the degree of support against the lateral ridges of the I-beam, thereby allowing compensation for increased wear tolerances over time. The device also employs an improved damping system including a pair of damping cylinders between the telescoping inner and outer casings, plus a master brake cylinder mounted on damped spring-brackets.

Abstract: A suspension system with a shock absorber having a manually adjustable lock-out valve and a blow-off valve for controlling damping characteristics suitable for a wide variety of large, medium, and small bumps, and rider induced suspension action, while selectively providing a stiff suspension for increased drive line efficiency. The shock absorber includes a damper containing a non-compressible fluid. A piston dividing the chamber into two portions has a primary channel and a secondary channel. A lock-out valve is coupled to the primary channel and is manually movable from an open position to a closed position. In the closed position, the hydraulic fluid is blocked from flowing through the primary channel to provide stiffened damping characteristics of the damper. In the open position, the hydraulic fluid can flow through the primary channel to provide softened damping characteristics.
