  • Patent number: 6439043
    Abstract: An apparatus for the static testing of a vehicle tire to determine displacement as a function of force of the tire. A tire is placed upon several cross members that are vertically adjustable where the cross members are vertically adjusted to simulate a particular road bed profile. A tire is then forced down upon the cross members and the force created upon the cross members is measured against the displacement of the tire.

  • Patent number: 6065198
    Abstract: A sealing element which forms a seal between a groove and an outer end of a crankshaft is installed by the use of a guide plate, an adapter and a press. The sealing element can be stretched over a frustoconical wall of the guide plate and slid along the cylindrical wall thereof on the outer end of the crankshaft. An adapter is then secured to the outer end of the crankshaft so that the press may be engaged over the adapter in sliding contact therewith to move the sealing element along the outer end of the crankshaft and into the groove. The sealing element may be removed from the groove by a puller. A rim of the puller is aligned with the sealing element as a drill is extended through passages in the rim of the puller to form holes in the sealing element. Screws are extended through the passages and self-tap into the holes formed in the sealing element. The puller is then withdrawn to withdraw the seal from the groove.

  • Patent number: 5946644
    Abstract: A shaft position indicator in which a collar is formed on and moves on in accordance with a shaft. The collar is placed opposite an optical sensor and includes a notch which activates an optical sensor when the notch is located opposite the sensor. When the notch is opposite the sensor, a driving circuit outputs a voltage. When the notch is not opposite the sensor, the driving circuit outputs 0 voltage. The light source and sensor are placed a distance from the collar equal to the focal length to substantially eliminate interference from ambient light.

  • Patent number: 5913945
    Abstract: A robotic device for operating a control pedal of a vehicle having a body and a pedal actuator mounted on the body. A telescoping connecting rod is coupled to the pedal actuator through a bell crank assembly, and further coupled to the control pedal for reciprocating motion thereto. The robotic device causes the pedal to be depressed and released when the pedal actuator reciprocates the telescoping connecting rod.

  • Patent number: 5835867
    Abstract: A base plate for a robotic system for automated durability road testing of a vehicle includes a seat surface positionable against a seat of the vehicle. A plurality of walls extend upwardly from and bound the surface when the surface is positioned against the seat, and a ballast space is established between the walls.

  • Patent number: 5821718
    Abstract: A robotic system for automated durability road testing of a vehicle includes a robotic body that is positioned on a base plate, and the base plate in turn is positioned on the driver's seat of a vehicle. The robotic body includes a brake pedal bell crank assembly for operating the brake pedal, and an accelerator beel crank assembly for operating the accelerator pedal. Additionally, the robotic body includes a steering wheel shaft that is engaged with the steering column of the vehicle for turning the vehicle, and a shift mechanism engaged with the gear shifter of the vehicle to shift the gears of the vehicle.

  • Patent number: 5816106
    Abstract: A device for coupling a robot to a column-mounted shift lever of a vehicle includes a line extending between the robot and shift lever for holding the shift lever in an unlocked position. An adapter is attached to the lever, and an actuator is coupled to the adapter via a ball joint. The actuator is also coupled to the robot for movement of the actuator to move the shift lever.

  • Patent number: 5602450
    Abstract: An apparatus for remotely operating an ignition switch mounted on the steering column of an automobile includes a motor mounted on the floor or other surface of the automobile away from the steering column, such that the steering column does not bear the weight of the motor. A drive cable is connected to the motor, and the drive cable is also connected to a coupling which is mounted on the steering column and which is connected to the ignition switch. The coupling translates rotational motion of the drive cable 90.degree., so that the coupling and drive cable do not unduly project straight out from the steering column and hence do not interfere with other components, e.g., shift levers, that are mounted on the steering column. A position sensor generates a signal representative of the position of the ignition switch, and the signal is received by a controller. In turn, the controller activates the motor as necessary to establish and/or maintain a desired position of the ignition switch.
