  • Patent number: 6318525
    Abstract: The present invention provides a shock absorber having improved damping. On the base of the shock absorber there is fastened the bottom of a barrel on which rests the counter-acting spring which urges in expansion the piston of the shock absorber. The barrel contains damping fluid and has a piston which is axially movable with lateral seal. The shock absorber also has an external secondary flow dampening device which is connected to the base of the shock absorber via a tube. In the strut base, and the connecting appendage there is a plug adjustment which moves laterally and limits an alternative path of flow for the liquid through the base flow damper and the piston flow damper respectively. By acting on the plug adjustments it is possible to adjust the braking level in expansion of the strut. Each flow damper also is affixed with a shim. The shim on the piston flow damper will flex at an appropriate pressure in the expansion phase, thereby damping the reaction of the strut to expansion.

  • Patent number: 6318524
    Abstract: A piston-cylinder unit includes a cylinder with a piston rod guide and a piston rod with a piston axially movably mounted in the cylinder so that the piston rod runs through a hole in the piston rod guide. A movement determination device comprising a transmitter portion and a receiver portion determine the movement of the piston from the travel time of waves generated by the transmitter portion. The movement determination device is arranged inside the piston rod guide, and waves reflected by the piston-piston rod component group are analyzed to determine the movement of this component group.

  • Patent number: 6318527
    Abstract: A novel apparatus and method are provided to reduce the interlaminar shear loading in the retention area of composite springs used in a vibration isolator for use with a helicopter main rotor. The composite springs, which are made of a graphite laminate, are weakest when subject to inter-laminate shear. The shear forces are highest during bending and twisting about the longitudinal axis of the laminate composite. The invention consists of several techniques to minimize the inter-laminate shear. The first is the use of nylon mounting pads which are attached to the ends of the graphite laminate spring arm at the locations where mounting to the inner and outer hubs is to take place. In particular, it has been found that the nylon spacer must be recessed back from the perimeter edges of the graphite spring arm the same distance which is approximately equal to the width of the graphite spring arm.

  • Patent number: 6318521
    Abstract: A vibration damping device is mounted between two spaced portions of a vehicle for absorbing road forces exerted on the vehicle. A cylindrical housing forms an internal piston chamber and is connected at one end to one portion of the vehicle, with an outer end of the rod of a piston which is slidably mounted within the piston chamber, being connected to another portion of the vehicle. A fluid transfer duct is formed between the housing and piston and provides communication between fluid subchambers formed on opposite sides of the piston within the piston chamber. An electrode is attached to either the housing or piston for applying a voltage across the duct to affect the rheological response of an electrorheological (ER) fluid flowing therethrough to provide a controllable mechanism to modify the damping force characteristics of the device. Each end of the piston rod is slidably supported by a slide bushing assembly which is mounted within an end of the housing.

  • Patent number: 6315336
    Abstract: An oven latch includes a base, a pivot, and a latch arm with a slot that engages the pivot and allows the latch arm to slide and rotate relative to the pivot. A motor mounted on the base rotates a cam, and a rod connected between the cam and the latch arm closes the latch when the cam turns, thereby pivoting the latch arm closed to engage the oven door and sliding the latch arm inwards along the latch arm slot to pull in the door. The pivoting and sliding motion of the latch arm is controlled by a guide slot formed in the base having a normal guide portion and a repair guide portion. During normal operation, an end of the rod moves along the normal guide portion of the guide slot. If the motor fails, the end of the rod may be manipulated into the repair guide portion of the guide slot to open the latch when the motor and cam are in the closed position.

  • Patent number: 6315372
    Abstract: A brake pressure control device of a road vehicle has an automatic control of a starting clutch and/or of a transmission. During a stoppage of the motor vehicle achieved by a stoppage braking, the driver can, by a respective arbitrary activity, trigger a “starting assist” function for a defined time period. During this function, a continuation of the stoppage braking takes place by maintaining a brake pressure controlled into the wheel brakes by pressure maintaining valves so that, during the above-mentioned time period, the driver can change over to the accelerator pedal.

  • Patent number: 6315085
    Abstract: A semi automatic brake applicator for wheel chairs which have at least one arm with an actuator lever pivotally attached to the arm, an actuator rod pivotally attached to the actuator lever at the first of two ends and to a clamp at the second end, the clamp being attached to the brake actuator lever of the wheel chair brake system. In operation, the actuator lever is rotationally pivoted which causes the actuator rod to move linearly which, in turn, causes the clamp to rotate the brake actuation handle thereby bringing the brake shoe into contact with the drive wheel thus setting the brake. Reverse motion of the actuator lever causes the brake to release.

  • Patent number: 6312064
    Abstract: A brake force control apparatus which can always accurately generate a brake force confirming to a driver's intention is provided. The brake force control apparatus performs brake assist control for supplying an increased brake fluid pressure which is greater than that generated in a regular brake operation to a wheel cylinder of a vehicle when an emergency brake operation is performed by a driver. A deceleration of the vehicle is detected. Additionally, a difference between a target deceleration which is to be generated during execution of the brake assist control and the deceleration is detected. A brake fluid pressure which is supplied to the wheel cylinder during execution of the brake assist control is controlled based on the difference.
