Abstract: A control method of a hydraulic pressure source-driving type vehicle hydraulic brake system is provided in which water hammering or worsening of the brake feeling does not occur when brake liquid is replenished through a replenish passage. A motor for driving a pump is actuated at a full driving force with an on-off valve in the brake liquid replenish passage opened in the stage in which the hydraulic pressure difference between the master cylinder pressure and the brake hydraulic pressure is small. Also, in the stage in which the brake hydraulic pressure is increased, so that the hydraulic pressure difference from the master cylinder hydraulic pressure has entered a predetermined range, a solenoid valve in the replenish passage is closed to return to the normal control in which the driving force of the motor is controlled so as to correspond to the hydraulic pressure difference.

Abstract: To apply hydraulic pressure to a wheel brake upon failure of a stroke simulator, a brake pressure control device for automotive vehicles is designed so that when a power pressure source is in the normal condition, fluid communication between the master cylinder and the wheel brake is interrupted and fluid communication between the master cylinder and the stroke simulator is established, thus causing the output hydraulic pressure of the power pressure source to be adjusted in response to a detection output of a master cylinder hydraulic pressure sensor, thereby applying the resulting hydraulic pressure to the wheel brake. In addition, the brake pressure control device is provided with a stroke sensor which detects a stroke of a brake pedal. When the stroke of the brake pedal exceeds a predetermined stroke, a simulator cut-off valve is closed to interrupt fluid communication between the master cylinder and the stroke simulator.

Abstract: A shock absorbing adjusting structure includes a cylinder with a tube movably received in the cylinder. One end of the cylinder is connected to a part of a bicycle frame and one end of the tube is connected to another part of the bicycle frame. A sleeve is fixedly connected to the cylinder and connected to a piston assembly movably inserted in the sleeve. A tapered hole and a plurality of through holes are defined through the piston assembly. A seal member is urged by a spring in the piston assembly and seals the through holes. A pusher in the piston assembly is urged by a rod which extends from an inside of the cylinder and is movably received in the sleeve. The rod is moved by an actuating bar which is operated by a rider from outside of the cylinder so as to movably adjust a tapered tip of the rod relative to the tapered hole in the piston assembly.

Abstract: The parking brake of a vehicle is operated by a power-generating generating actuating unit 4. For maintaining the function of the parking brake in the event of a failure of the power operating device 1, an emergency operating device 2 is provided which can be operated by muscle force. Both operating devices 1, 2 have mechanical transmissions 5, 12 which act upon a common threaded spindle 3 for tensioning and releasing the parking brake. By way of the mutual self-locking design of the mechanical transmission 5, 12 which depends on the type of operation, it is achieved that both operating modes (power or muscle force) can be carried out in any sequence and without any limitation of the adjusting path(s).

Abstract: A bush-type hydraulically damped mounting device has two telescoped anchor parts. Resilient walls, spaced apart axially, extend between the anchor parts. Deformable walls, spaced apart circumferentially, extend axially between the resilient walls, to define first and second chambers for hydraulic fluid. The deformable walls make abutting unbonded contact with one or other of the anchor parts.

Abstract: A vehicle break assembly includes a sensor that detects the amount of movement of certain components within the brake assembly. In the preferred embodiment, a rotary sensor is coupled directly with the generally S-shaped cam member and provides signals that indicate the total amount of rotary movement of the cam member during breaking applications. These signals provide information indicative of the amount of slack or stroke during braking applications and provide indications of the conditions of brake linings associated with the brake shoes within the brake assembly. The sensor information preferably is communicated to a vehicle operator in a manner that indicates whether an inspection or maintenance of the braking system is advisable.

Abstract: A spring assembly having a coil containing a core and methods and apparatus for manufacturing same are disclosed. The coil includes a core between reduced portions of the coil. One device for manufacturing the coil includes a coiling machine having an insert device operable with a coiler. The coiler is programmed to form coils of appropriate diameter along the length of the coil, including a diameter sufficiently large to contain the core and two diameters sufficiently small to retain the core in the coil. The insert device transfers the core to the coil after the first small diameter is formed and before the second small diameter is formed. The coil with the core contained between the two small diameters is thereby manufactured in a unified automated process.
