A spring plate for supporting a coil spring of a vibration damper includes a metal base body and a plurality of discrete insulating segments positioned on the base body. Each insulating segment has a contact surface which contacts an end of the coil spring, and an edge part which prevents the spring from migrating radially. Each insulating segment can be replaced independently of the other insulating segments.

Method for adjusting the throttling action of a valve comprising a valve body with at least one through-channel for a working medium, where the working medium is throttled by at least one valve disk which covers the throttle channel. By making use of the effect of the heat of a laser beam to change the elastic pretension of the disk, deviations from a predetermined throttling action are minimized. The laser beam is used to cause partial local melting in the minimum of one valve disk, the heat thus introduced having the effect of working at least one defined bending axis into the disk.

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.

A non-railbound vehicle with an electric motor in which the maximum output of the internal combustion engine will be available in its entirety for driving the vehicle without prejudice to convenience with respect to electrical actuation of accessory functions. The vehicle includes a drive control that provides a portion of the output generated by a generator for supplying power to the low-voltage vehicle power supply. The electronic drive control is programmed to provide a temporary interruption of the current supplied by the generator to the low-voltage vehicle power supply during operating phases in which the full output of the internal combustion engine is required for driving the vehicle. During these phases current is supplied to accessory electrical consumers via the vehicle battery.

An apparatus for determining a critical driving torque and information representing the coefficient of friction at the wheel grip limit for a vehicle having a plurality of driven wheels. It is suggested that torque control devices be assigned to at least two of the driven wheels so that the ratio of the driving torques of the two driven wheels can be varied, wherein torque sensing device generate a torque signal corresponding to the magnitude of at least the greater of the driving torques of the driven wheels. A wheel slip sensing device is associated with the driven wheels and detects an increase in the slip of the wheel with the greater driving torque beyond a predetermined limit. The information on the coefficient of friction is generated depending on the magnitude of the detected driving torque of the wheel whose slip exceeds the limit. To determine the information concerning the coefficient of friction, the distribution of driving torque between the front axle and rear axle is periodically increased in an alternating manner.

A locking device includes a key and a reading device. The key has a grip portion and a plurality of information carrier parts attached to the grip portion. The information carrier parts determine the locking code for the key. Each information carrier part is arranged to receive an information element and the carrier parts are adjustably positionable for disposing the information elements into a predetermined angular pattern. The reading device is arranged to read the locking code on the key and to compare it with a predetermined locking code for operating a lock. The information carrier parts are mounted on a member extending axially from the grip portion of the key. The carrier parts are angularly adjustably positionable about the axis of the member. The reading device contains elements for the detecting the presence or absence of the information elements in predetermined angular positions.

Vibration damper includes a tubular body to which an external part, which acts as a stop, is fastened. A component such as a steering knuckle, which is supported against the stop, is also fastened to the tubular body. When a normal load on the component is exceeded, a deformation area allows the component to shift on the tubular body.

For the individual drive of a wheel of a motor vehicle, a planetary transmission can be combined into a single module with a motor. The planetary transmission has a sun wheel which on a motor shaft of the motor, a ring gear and a planet carrier with planet wheels which are rotationally mounted on journals. The planet carrier and the ring gear are non-rotationally connected to a support part which simultaneously forms the transmission housing, or to a driven shaft part which is rotationally mounted on the support part. The planet carrier is designed as a shaped sheet metal and comprises a sheet metal base wall which runs axially perpendicular to the axis of rotation of the planetary transmission, into which sheet metal base wall the journals are shaped in a cup shape. Projecting in the same direction as the journals from the outside circumference of the sheet metal base wall is a circumferential wall in which there is a toothed portion for the non-rotational coupling of the planet carrier with the support part or the driven shaft part. The planet wheels are held by a ring-shaped positioning disc on the shaped sheet metal part. Projecting axially from the outside circumference of the positioning disc are webs which are engaged between neighboring planet wheels, and which are welded to the sheet metal base wall. The planet carrier can be manufactured easily, and the forces which are exerted on it during operation are essentially equalized or compensated.
