  • Patent number: 6260835
    Abstract: The invention is directed to a vibration damper such as a shock strut for articulated installation between a car body and a wheel guide part in a motor vehicle by a quick connection. For this purpose, the vibration damper on the shock strut, together with an elastic joint and a connection part, forms a constructional unit or assembly unit. The quick connection is formed between the connection part and the body or the wheel guide without a catch connection and in a rigid manner, so that relative movement is prevented between the connection part and the body or wheel guide part.

  • Publication number: 20010006141
    Abstract: A driver disk for a clutch plate includes a facing carrier for holding friction facings. The facing carrier is designed in one piece with facing springs for axial suspension of the friction facings. The facing springs are constructed as pot-shaped protuberances and have a flat area provided for contacting the friction facings. Since the facing springs are made as one piece with the facing carrier, the driver disk has only a small number of structural component parts and can be produced very economically.

  • Publication number: 20010005065
    Abstract: A self-pumping hydropneumatic spring strut with internal leveling is provided for use in motor vehicles having an oil filled working cylinder, which is under the pressure of at least one gas cushion arranged in a high pressure chamber and acting as a spring. The high pressure chamber is connected to a working space, wherein a bleed opening forms a flow connection between the working space and the low pressure chamber. The bleed opening can be closed as a function of the position of the working piston in the working cylinder. The spring strut is assigned an actuator which displaces the spring strut in the vertical direction. The actuator can displace the motor vehicle to a plurality of displacement distances without requiring any electrical or electronic control, complex external leveling devices, or displacement detection systems.

  • Patent number: 6250201
    Abstract: A throttle device for use with a hydraulic adjustment devices that have an input cylinder and an output cylinder and a hydraulic line filled with fluid connecting the output cylinder and the input cylinder, is arranged in the hydraulic line for establishing various throttle resistances to the flow of the fluid in both flow directions through the hydraulic line. The throttle device includes a disk with at least one boring and/or at least one passage channel. The disk moves back and forth, as the fluid flows, in both flow directions, and thereby strikes against a first stop in one direction and against a second stop in the other direction. The throttle device in the form of a disk in the movement space which is a transition from the hydraulic line to the supply line of the cylinder in its diameter, with a stop disk secured in the hydraulic line forming the second stop is economically advantageous. The disk that acts as the valve is distinguished by its low cost.

  • Patent number: 6249723
    Abstract: A hybrid drive for a vehicle in which the driving power provided by an internal combustion engine (ICE) or an electric motor may be fed via a transmission with a transmission input shaft and a transmission output shaft to the drive train. The ICE and the electric motor are connectable to each other via a coupling and the electric motor is directly connected to the transmission. An electric energy storage device is connected to the ICE for receiving a charge and to the electric motor for providing power to the electric motor. The hybrid drive is designed so that the torque that can be provided by the electric motor is greater than that of the internal combustion engine. In addition, the transmission input shaft always turns in the same direction as the transmission output shaft so that reverse drive by the hybrid drive is only possible using the electric motor.

  • Patent number: 6237334
    Abstract: A hydraulic actuation device for the adjustment of units in motor vehicles includes a piston-cylinder unit with a housing and a piston displaceably arranged in the cylinder portion of the housing and/or in a guide sleeve in the housing. The piston-cylinder unit may be a slave cylinder or a master cylinder. The cylinder has a connection channel along one of its surface lines with an outer channel wall which is located in a portion of the connection channel located farthest from a center axis of the cylinder. The outer channel wall approximately follows a straight line and has an angle of inclination relative to the center axis which is greater than zero and preferably equal to or greater than a maximum installation angle of the installed position of the housing. The described arrangement of the deaeration bore hole at the highest possible location in the pressure space of the cylinder is advantageous for a deaeration of the hydraulic system for repairs and servicing.
