Patent DE-4133622-A1 (DE)
Inventor: ADLER UWE DIPL ING
IPC: B60L50/15
Filed: 1991-10-10
Abstract: For a drive arrangement of a motor vehicle whose wheels (13) are driven by separate electric motors (11) and the electric motors (11) are powered from a generator arrangement (3) driven by an internal combustion engine (1) via a d.c. intermediate circuit (7), it is proposed that the rotation speed of the internal combustion engine (1) and the individual wheels (13) be detected by rotation speed sensing circuits (31, 17) which respond to pulsed signals from commutation circuits (5, 9) of the generator arrangement (3). The commutation circuits (5, 9) generate the pulsed signals dependently upon position transmitters (15, 17) arranged on the generator arrangement (3) or on the electric motors (11). The rotation speeds can thus be precisely detected solely on the basis of components existing in the drive arrangement. The rotation speed detection is fitted especially in combination with an anti-lock braking system (ABS) and a drive slip regulating system (ASR).

There is a control boss on the striker, protruding between the members. ADVANTAGE - Compact and light in weight.
Patent DE-4136988-A1 (DE)
Inventor: PFLUEGNER WOLFGANG DIPL ING
IPC: F16C19/50
Filed: 1991-11-11
Abstract: Described is a ball bearing (3) for shafts subject to linear motion, in particular for vehicle-transmission gear-shift rods (2) held in place by a spring-biased securing element which acts radially on the rod. The invention calls for the outer bearing ring and the ball races enclosed by it to have a common radial gap through which one end of the securing element, which is in the form of a pin (4), projects and makes contact with the gear-shift rod (2). This design allows the securing element to act on the shaft in the immediate vicinity of the bearing.

Filed: 1993-03-05
Abstract: A fuel injection pump for internal combustion engines, comprises a pump piston (4) which is axially guided in a cylindrical bore (3) of a cylinder liner (2) to define therewith a pump working chamber (6). Two mutually diametrically opposite control grooves (8) are permanently connected to the pump working chamber (6) and cooperate with a radial discharge bore (23) in an annular slider (13), thereby to end delivery. The commencement of delivery is controlled by a commencement of delivery bore (25) disposed in the pump piston (4), and connected to the pump working chamber, entering the axially displaceable annular slider to prevent the escape of fuel from the pump working chamber. For more uniform application of the force of the high fuel pressure onto the interior wall surface of the annular slider, the outlets of the commencement of delivery bores (25) are disposed between the ends of the oblique grooves (8) remote from the pump working chamber. In this way non-uniform distortion of the slider is avoided. <IMAGE>
