Abstract: A double row bearing includes a shaft and an inner ring mounted on the shaft. A preloading collar is fixedly mounted on the shaft and an elastic member is disposed between the inner ring and the preloading collar so that the preloading collar applies a predetermined preload to the inner ring through the elastic member. This structure compensates the reduction of the preload due to the temperature rise of the bearing and axial displacement of the inner ring of the bearing.

Abstract: A compressed-air processing system, notably for motor vehicles, includes, in a housing, an electromagnetic pressure regulator and a multicircuit safety valve having at least one load circuit connected to it. Each load circuit can be locked separately by an assigned pressure control unit. Reliable and economical operation of the system is achieved by positioning a pressure limiter between at least one of the pressure control units and the pressure regulator output and by the fact that in the zero-current state, the pressure limiter acts on a supply hole for the control unit so as to limit the output pressure to a defined value.

Abstract: A vibration absorber for absorbing a vibration between first and second members each of which is connected to the vibration absorber, includes a movable member adapted to contact with a fluid, and including a portion connected mechanically to one of the first and second members so that a movement of the fluid and a movement of the portion of the movable member correspond to each other, and a fluid moving member for flowing the fluid in either of an extension direction in which the portion of the movable member moves to increase a distance between the first and second members and a contraction direction in which the portion of the movable member moves to decrease the distance between the first and second members in such a manner that the vibration is restrained by a change of the distance between the first and second members from being transmitted between the first and second member.

Abstract: A rotary damper for use in motor vehicle suspensions comprising a rotor disposed within damping fluid in a fluid chamber of a case to form fluid volumes, with valves for flow control and an accumulator for fluid fill variation and thermal expansion mounted internal to the rotor. A first check valve and first control valve mounted in a first flow passage within the rotor allow flow from second fluid volume to first fluid volume, but restrict flow from the first fluid volume to the second fluid volume. Similarly, a second check valve and a second control valve mounted in a second flow passage within the rotor allow flow from the first fluid volume to the second fluid volume, but restrict flow from the second fluid volume to the first fluid volume. Thus, the valves are configured to provide independent control of damping for each direction of rotation.

Abstract: A control system for a selective clutch that prevents interference with automatic engagement/disengagement of a friction clutch (2) when manual engagement/disengagement is selected at the time of starting a vehicle. The selective clutch includes an autoclutch device that automatically disengages and engages the clutch (2) using an actuator (10) under the control of a controller (6, 9). The selective clutch also includes a manual clutch device that allows engagement and disengagement of the clutch based on depressing of a clutch pedal (11). The clutch disengagement and engagement by the autoclutch device is prohibited, or the prohibition is canceled, based on a vehicle velocity (28), gear speed (23) of a gear box (3), and clutch pedal depression (16).

Abstract: A method for controlling the traction slip of a vehicle on a roadway with sidewise different coefficients of friction includes the following steps: identifying a driving situation on a roadway with sidewise different coefficients of friction and, when the driving situation is identified and traction slip is encountered on both wheels, decreasing the brake pressure of the driven wheel on the low coefficient-of-friction side. A device for controlling the traction slip of a vehicle on a roadway with sidewise different coefficients of friction includes a determining device for determining a driving situation on a roadway with sidewise different coefficients of friction, and a brake actuation control which decreases the brake pressure of the driven wheel on the low coefficient-of-friction side when the driving situation is identified and traction slip is encountered on both wheels.

Abstract: A method and device for driving an arrangement, in a vehicle, that delivers a pressurized medium in a brake system, the pressurized medium being delivered in at least one brake circuit of the brake system, and a pressurized medium volume available in the brake circuit being dependent upon the driving of the arrangement delivering the pressurized medium. In this context, the arrangement delivering the pressurized medium is driven as a function of the vehicle speed so as to effect a correlation between the vehicle speed and the pressurized medium volume available in the brake circuit. This means, in particular, that the vehicle speed and the pressurized medium volume available in the brake circuit are linked in such a way that, with rising vehicle speed, the available volume of pressurized medium in the brake circuit is increased, and/or with falling vehicle speed, the available volume of pressurized medium in the brake circuit is decreased.

Abstract: A modular blow-off base valve is provided for a vehicle twin tube damper in which a valve body is inserted into the end of an inner damper tube. The valve body has a central opening into which is inserted a valve cage assembly. The valve cage assembly includes a valve cage tubular member having a blow-off valve opening which is pressed into the central opening. A valve stem forming a valve seat with the blow-off valve opening is biased into a closed position by a helical spring seated against the underside of the valve stem at one end and a spring retainer fastened to the bottom of the valve cage at its other end. An annular bleed disc, intake disc and washer disc fit over the tubular member and cover rebound openings in the valve body. When the valve cage assembly is placed into the valve body's central opening, the washer disc biases the intake disc into sealing engagement with the rebound openings in the valve body.

Abstract: An electric parking brake includes a motor and a transmission coupling a threaded lead screw to the output shaft of the motor. The transmission preferably includes a plurality of helical gears such that the lead screw and the output shaft are coaxial. A guide shaft extends substantially parallel to and spaced apart from the lead screw. A drive nut threadably receives the lead screw and slidingly receives the elongate guide shaft. A brake cable is connected to the drive nut at a position preferably located midway between the lead screw and the guide shaft. In operation, rotation of the lead screw causes linear motion of the drive nut along the lead screw and the guide shaft which causes tensioning and untensioning of the brake cable. The assembly preferably includes a manual override device operatively connected to the lead screw for manual rotation of the lead screw.

Abstract: A brake fluid pressure retaining apparatus RU is mounted on a vehicle equipped with an automatic transmission CVT and a driving motor control unit DCU. The driving motor control unit switches the magnitude of creep driving force between a greater condition and a smaller condition in accordance with a depression of the brake pedal, so that the driving force is made smaller at a depression of the brake pedal than at a release of the brake pedal. The brake fluid pressure retaining apparatus continuously retains brake fluid pressure within a wheel cylinder WC after releasing a brake pedal BP. The retained brake fluid pressure is released after the driving force increases to the greater condition and when a first setting time TM1 passes.
