Abstract: An axial setting device having two discs (24, 29) which are rotatable relative to one another, which are supported coaxially relative to one another and between which there are guided balls (35) in pairs of ball grooves (34, 39) whose depth varies across the circumference. One of the discs (24, 29) is axially supported and one is axially displaceable against elastic returning forces of first spring (33). At least one of the discs can be driven by a motor (11) via a gear drive. During the return movement of the discs (24, 29) after the balls (35) have reached their end position in the ball grooves, which end position is defined by the greatest groove depth, a second spring permits overshooting of the drivable disc (24) together with the disc (29) supported with respect to rotation against elastic returning forces of the second spring.

Abstract: In a hydraulic brake pressure control device of a load responsive type, a housing is attached to one of a rear wheel side member and a vehicle body side member which are connected with each other through a suspension mechanism and a lever is carried on the housing through a pivot axis to be pivotable toward the housing for direct or indirect abutting engagement with a piston formed with a valve portion. A spring member is interposed between a free end portion of the lever and the other of the rear wheel side member and the vehicle body side member for urging the lever toward the piston by means of a spring force depending on the distance between the rear wheel side member and the vehicle body side member. Further, an anti-vibration member is provided between the lever and the housing for moderating the collision of the lever with the piston when the lever is repetitively disengaged from, and engaged with, the piston during the vehicle running a bumpy road.

Abstract: The present invention provides a disc brake with an integral parking brake, in which a push rod, a push rod biasing member and a spring cover are formed into an assembly in the form of a single cartridge. The push rod is divided into two separate bodies, namely, a front body portion threadably engaged with a clutch member and a rear body portion engaged with a cam rod. In this disc brake, it is possible to prevent a loss of an output force of a piston under a high fluid pressure. There is no need to increase a diameter of a piston for compensating for such a loss of an output force of a piston, and a reduction in size of a disc brake can be achieved.

Abstract: A brake control device prevents movement of a vehicle, when an unsafe condition exists, by automatically applying the parking or other brake. The brake control system may prevent movement should the unsafe condition exist within, on or around, a towed device such as a trailer, a trailer-house or other recreational or non-recreational equipment. The brake control system may set a brake or parking device on the towed device whenever the towed device is disconnected from the motorized vehicle, or whenever equipment on the towed vehicle is extending outward or is otherwise un-stowed in a position unsafe for traveling, whether or not the towed vehicle is connected to the towing vehicle. Interface connections from the towed device to the powered towing vehicle may include wireless, electrical wire, fiber optics, analog, digital, or others.
