Abstract: In a vehicle having an ABS control system, a braking control of a right and left rear wheels can be independently carried out when a lateral acceleration exceeds a lateral acceleration value set beforehand. When the ABS control is operated at one of the right and left rear wheels, the control system executes a stepwise pressure increase control which provides a stepwise pressure increase for the other rear wheel up to a braking pressure to be reached at a start of the control.

Abstract: An automatic application hand brake apparatus is provided for automatically applying at least one brake member secured to a railway vehicle with the hand brake assembly. The apparatus comprises an operating member having at least one ratchet attached to a drive shaft of said hand brake assembly. An application cylinder is connected to a drive arm pivotally attached to the drive shaft and containing and operating pawl engaging the operating ratchet. The reciprocating motion of the drive arm caused by the application cylinder enables reciprocal rotation of the operating arm and furthermore causing application of at least one brake member. A plurality of control valves are connected to the source of the fluid pressure for initiating and regulating the supply of fluid pressure to the application cylinder and for stopping an automatic application of such hand brake in case of the emergency or a reversal of the unintended activation.

In this connection, the passenger compartment noises in the vehicle are ascertained, or at least one variable representing these is ascertained. The noise caused by the aggregate and/or the variable representing this is correlated with the passenger compartment noises and/or the variable representing these. Finally, as a function of that, the control or a control signal for the aggregate is generated and/or adapted.

Abstract: The underlying idea of the invention is to reduce the pressure force resulting from the inlet pressure and the outlet pressure of the back-up valve and affecting the valve body of the back-up valve. The valve body is a switching piston with a first and second switching piston side. The first switching piston side is pressurized by brake operating valve pressure or with brake cylinder pressure and the second switching piston side is pressurized on a first partial surface with brake cylinder pressure and on a second partial surface with brake operating valve pressure. The pressures affecting both sides of the switching piston thus cancel each other out.

The system includes vacuum pressure detecting means to adjust the hydraulic brake pressure in a appropriate condition. In response to the vacuum pressure detecting means, vehicle motion is controlled in the direction that the vehicle motion control is restricted under the vacuum pressure which drives said vacuum booster is relatively small. Also, the duration of the hydraulic brake pressure increase is controlled in the direction longer under the vacuum pressure which drives said vacuum booster is relatively small.

The first rotatable member normally is prevented against rotation in a brake releasing rotational direction. A second rotatable member is rotatable relative to the first rotatable member and includes cable attachment structure for affixing a brake activation linkage thereto. A clutch spring is disposed between the first and second rotatable members and is configured to contract upon initiation of rotation of the first rotatable member in the brake applying direction so as to couple the second rotatable member to the first rotatable member for affecting rotation of the second rotatable member in the brake applying direction.

Abstract: An electronically controlled brake system for automobiles is disclosed. This brake system has a low/intermediate pressure accumulator, which is connected to both the NC-type solenoid valves and the oil suction line so as to store pressurized oil discharged from the wheel brakes during an ABS pressure reducing mode, and feed the stored pressurized oil to the inlet of an oil pump during an ABS pressure increasing mode. This accumulator also stores pressurized oil outputted from the oil pump to feed the stored pressurized oil to the inlet of the oil pump during an ESP mode. The low/intermediate pressure accumulator of this invention thus acts as a low pressure accumulator during an ABS mode, and acts as an intermediate pressure accumulator during an ESP mode. Due to such a low/intermediate pressure accumulator, it is possible to reduce the number of parts making up the brake system.

Abstract: A “passive-active” mount includes an emanator-securement plate, a foundation-securement plate, at least one elastomeric “streamlined resilient element,” and at least one collocated motion sensor-vibratory actuator pair. The mount brings to bear, sequentially and complementarily, passive vibration control followed by active vibration as control. The passive vibration control is effectuated by one or more “streamlined resilient elements,” each attributed with a “constant natural frequency” (CNF) property whereby such element is naturally predisposed to passively reducing vibration at a particular frequency band regardless of the extent of the loading, within certain limits, to which such element is being subjected.

Abstract: A journal bearing for a high speed surgical drill and/or attachment for rotatably supporting a cutter is made from a polymer of polyimide resin and graphite material and is designed to have a polygon configured bore where there are two point contact of the mating surfaces of the bore walls and cutter's shaft and preferably the bore is square shaped in cross section. This bearing results in a decrease in the envelope size of the support tube and hence, the overall diameter of the surgical instrument at the distal end enhances the line of vision of the cutter to the surgeon when the surgeon is performing surgical procedures. The entrance ends of the intermediate bearings are countersunk to define a ramp to ease the egress of the tool bit shaft for entering the tube of the drill motor or drill attachment during the assembly thereof.

The latch members are arranged to move laterally apart relative to each other upon application of a force direction substantially towards the base member. The first and second latch members are arranged to selectively hold the catch members in a plurality of engagement positions having different heights above the base member.

The linkage is defined by a continuous wire that is shaped into a first engagement section that is separated from a second engagement section by a center section. The first engagement section is define by a loop that extends from the center section while the second engagement section is defined by a hook with an end that is spaced apart from the center section a distance that is greater than a radius of the hook such that a resilient force is required to move the end in a plane away from the center section and thereafter receive a loop on the brake cable through which an actuation force is transmitted to move a lever and effect a brake application.
