  • Patent number: 7316457
    Abstract: A motion control apparatus for a four-wheel drive vehicle performs over-steer suppressing control when the vehicle is in an over-steer state so as to apply a braking force to a front wheel located on the outer side of a turning locus without lowering engine output, and performs LSD control for the front/rear wheels when the obtained difference between wheel speeds of the left and right wheels exceeds an allowable limit so as to apply a braking force for suppressing idle rotation to the one of the left and right wheels that is of higher wheel speed. During execution of the over-steer suppression control, the braking force for suppressing front-wheel idle rotation to be imparted to the front wheel located on the inner side of the turning locus by means of the front-wheel-side LSD control is lowered, whereby the rear wheels become unlikely to produce excessive idle rotation.

  • Patent number: 7306077
    Abstract: The present invention relates to a fail-safe skate retarder that applies a braking force proportional to the weight of a rail car entering the retarder. Each segment of the retarder includes a lever mechanism with a pair of levers rotatably joined under the running rail. Each lever holds a braking rail for engaging a wheel of the car. The retarder is normally in a lower, fail-safe position with the brake rails closer together than the width of the wheel. When the car enters the retarder, the wheel forces the brake rails apart into a braking position, and the middle of the lever mechanism rises to lift the running rail and car. A hydraulic power unit and cylinder is activated to raise the middle of the lever mechanism even further to a release position so that the brake rails are spread apart more than the width of the wheel.

  • Patent number: 7303242
    Abstract: An adaptation to a vehicle antilock braking system modulator to increase the initial displacement of the master cylinder, provide quicker system response and improved pedal feel. A solenoid assembly is added to the non fluid side of each of the low pressure accumulators in the ABS modulator. Upon the operator initiation of a brake apply, the solenoids are energized to immediately push upon the sump pistons and inject fluid from the low pressure accumulators into the brake system. This extra “shot” of fluid decreases the amount of fluid that the master cylinder delivers to the brake system. This improves pedal feel as it reduces the required initial pedal travel for a given brake system displacement. The low pressure accumulator pistons are spring balanced to ensure retention of fluid between brake applies and to allow normal ABS operation. During ABS operation, the low pressure accumulator displacer solenoids are de-energized to allow effective operation.

  • Patent number: 7303052
    Abstract: A device for tightening and loosening a bicycle's brake wire is provided, which is installed between a handbrake operating device and a handbrake assembly of the bicycle. The device is mainly composed by a knob structure, a seat structure, and a tubular element. The knob structure and seat structure are configured such that their total length changes as the knob structure is twisted, which in turn tightens or loosens the brake wire of the bicycle. The gap between the handbrake assembly's brake pads therefore could be narrowed for the handbrake's normal operation, or loosened for dismounting the bicycle's wheel quickly and conveniently.

  • Patent number: 7303241
    Abstract: A pump drive motor control apparatus controls a motor used for driving a hydraulic pump. Every time the supply of electricity to the motor is resumed (every time the motor control signal changes from a low level to a high level), the apparatus measures a time which the voltage generated by the motor requires to decrease by a predetermined amount, the time indicating the decreasing speed of the generated voltage. The apparatus normally sets the high-level maintenance time, in which the motor control signal is maintained high, to a base time. When a state in which the measured time is not longer than a reference time is detected a predetermined number of times (3 times) or more, the apparatus determines that the load of the pump is heavy. In such a case, the apparatus increases the average rotational speed of the motor by increasing the high-level maintenance time.
