Abstract: In a disc brake with automatic adjusting device, a nut (12) is screwed to an axially slidable, unrotatable spindle (11). Nut (12) is connected to a coupling element (13). An auxiliary piston (32) is slidably mounted in a bore (31) of the brake piston (4) and is connected to the nut (12) by an axially lockable snap-in connection (35, 37, 38).

Abstract: A self-adjustment mechanism for a brake system includes a first sprag clutch seated in a support. An eccentric serves as an inner race for the first sprag clutch and as an outer race for a second sprag clutch. A timing assembly serves as an inner race for the second sprag clutch and includes first and second spaced-apart pins projecting from a surface. An arm is pivotally connected to the timing assembly and positioned between the pins. A brake apply cam engages a first end of the arm so that it pivots with respect to the timing assembly. As the arm pivots, a brake apply piston is engaged. A pivot center of the arm is selectively rotated by the eccentric to maintain the phase relationhip of the cam and the brakepack as the plates wear.

Abstract: An apparatus for a drum brake for mechanically actuatable self-energizing internal shoe-type drum brakes for automotive vehicles. A pair of brake shoes (4, 5) is arranged on a brake carrier plate (27) at a thrust member (6) and furnished with tension springs (7, 10). A mechanical actuating apparatus acts between a pair of brake shoe ends (4, 5) disposed opposite each other and prestressed by springs (7, 10). The mechanical actuating apparatus presses the brake shoes (4, 5) for braking against a brake drum (1) enclosing them and a first automatically clearance compensating adjusting device is arranged between the brake shoe ends as well as a second adjusting device arranged at at least one brake shoe web (12) supporting the brake shoe (5).

Abstract: A hydropneumatic brake actuator having a friction member positionable by a power piston during a brake application stroke through a lost-motion connection therewith to establish a stop to limit return movement of the power piston during a brake release and thereby provide a predetermined brake shoe clearance. The friction member comprises an elastomeric-type O-ring that can be compressed axially to varying degrees, thereby adjusting the radial force that the O-ring exerts on the piston bore.

Abstract: A disk brake actuator having a hydraulic slack-adjusting arrangement for maintaining a positive clearance between a brake shoe and a brake disk, includes a cylinder housing having disposed therein a brake-applying spring section, a hydraulic-operated release section, and an actuator piston spindle arrangement operably-connected to the spring section by way of a clutch arrangement. A flange, formed on the actuator piston, acts as a plunger during a brake application and draws a first amount of hydraulic fluid into a first storage area, such first amount corresponding in volumn to the clearance between the brake disk and brake shoe when a nonworn brake shoe is first used. Upon release of the brake, the actuator piston forces the hydraulic fluid back into a second storage area wherein is included a shuttle member movable with a shuttle chamber. Additional hydraulic fluid is drawn from a reservoir when actuator piston movement, beyond the original clearance value, occurs as a result of brake shoe wear.

Abstract: A brake for a vehicle adapted to be used for an off-road 3-wheel motor cycle or 4-wheel vehicle. This brake has a wheel, an axle rotated integrally with the wheel, a cylindrical hub rotatably engaged with the axle, a chamber formed in the hub and a multi-disc brake provided in the chamber. Thus, the brake is hardly affected by the influence of sand, mud and water scattered when the vehicle is running, and the tires and wheels can be readily cleaned when the vehicle is cleaned.

Abstract: A negative acting disc brake provided with arrangement for automatically adjusting the clearance between the brake pads and the disc caused by abrasion of the brake pads. The entire amount of abrasion is absorbed not by a single release of brake but by several times of release of brake.

Abstract: A drum brake of the inner shoe type has a self-adjusting device which comprises a push rod, one end of which cooperates with a first brake shoe, while the other end cooperates with a second brake shoe with the intermediary of an adjusting wedge, the position of which determines the effective length of the push rod. In the released state of the brake, the brake shoes abut the push rod-and-wedge assembly, whereby an air gap is defined between the brake lining and the drum. A clamping spring urges the push rod and the second brake shoe against the one and the other wedge flank. The wedge angle of the adjusting wedge is so selected that normally no shifting of the wedge occurs. The push rod has an abutting and displacing arrangement which--as soon as the brake shoe travel exceeds, during brake actuation, a basic structurally determined desired air gap--shifts the push rod against the force of the clamping spring and thus loosens the wedge.

Abstract: A braking assembly includes a carrier for a hydraulically actuated braking piston; a shaft movable axially to also displace the piston, a rotary actuator member, and a coupling responsive to rotation of the rotary member to effect advancement of the shaft toward the piston, accompanied by gripping of the shaft.

Abstract: A mechanically actuated disc brake includes a wedge actuator which urges an extensible, force transmitting member toward the disc brake rotor in order to effect a brake application. A ratchet mechanism is carried by the extensible member and by a piston slidably mounted within the brake housing. The ratchet mechanism is responsive to movement of the extensible member toward the rotor in access of a predetermined amount in order to effect elongation of the extensible member to limit retraction in the piston, so that retraction of the friction elements is similarly limited. The extensible member also cooperates with a manual adjustment mechanism which may be used to manually adjust the brakes or to "back-off" the extensible member to permit movement of the friction elements away from the disc in excess of the predetermined amount when the friction elements must be removed when the brake is serviced.

Abstract: A device which in normal use restricts relative movement between two members to one direction. Attempted movement opposite to the one direction causes an hydraulic lock to prevent such attempted movement, which also causes wedges actuated by the hydraulic lock to engage in locking co-operation to prevent the attempted movement instead of or in unison with the hydraulic lock.
