摘要:
A propulsion system for a vehicle comprising an electric motor, circuit breakers which switch field windings of the electric motor, as well as a cooling device which cools the field windings and the circuit breakers by its coolant circuit. The electric motor is realized in the form of a first modular unit which is mechanically functional in itself. The circuit breakers are assembled in at least one second modular unit, which is connected firmly to the first modular unit to form a propulsion unit. The individual modular units can be separated from one another and are connected to one another both by detachable electrical interface connections and also by detachable coolant interface connections. This construction makes it possible to selectively expand the propulsion unit by adding additional modular units, or in the event of the failure or malfunction of individual modular units to replace the modular units without having to replace the entire propulsion unit.

A pulled membrane spring clutch, whereby the membrane spring is supported with its outside diameter on a plate spring, which membrane spring has a rather large load pressure. The resulting load pressure acts on a mechanism which makes an automatic adjustment to compensate for wear to the friction linings, whereby the membrane spring retains its position relative to the clutch housing.

A self-actuating vibration damper for use in a pneumatic suspension system of a motor vehicle having an air spring that defines an air chamber is disclosed. Located within the air chamber is an actuator rod mounted between two air valves. Upon application of a sufficiently heavy load to the vibration damper, a first end of the actuator rod closes the first air valve to prevent release of air from the air chamber to the outside atmosphere, and a second end of the actuator rod opens the second valve to admit compressed air into the air chamber.

A membrane spring clutch with an automatic wear compensation mechanism. This mechanism provides a ring element between the outside circumference of the membrane spring and the application plate, which ring element is in contact with the application plate and an encircling ring surface, and is provided with oblique surfaces facing the membrane spring. The corresponding opposite surfaces in the membrane spring are produced by plastic deformation of areas of the membrane spring.

A motor vehicle friction clutch with a pressure plate which is fastened with the interposition of a clutch disc with friction linings to a flywheel, and which has a common axis of rotation with the flywheel, comprising an application plate located non-rotationally--but so that it can move axially--in a clutch housing, and an application means to apply the application force, is designed so that the amount of work which must be performed by an application means for the engagement and release of the clutch becomes minimal. For this purpose, the clutch housing is provided with an axial guide for a transmission element located between the application means and the application plate, on which the transmission element, as long as there is a separation between the application plate and the friction linings of the clutch disc during an engagement and release movement, can track the movement of the application plate, while as soon as the application plate comes into contact with the friction linings of the clutch disc, the application plate can be clamped fast by means of a change in the angle initiated at its contact point with the application plate for the transmission of the application force, with the formation of a lever arm between this contact point and the engagement point of the application means on the axial guide.

A torsional vibration damper is designed with a driving-side transmission element, with at least one planet carrier which can rotate relative to the transmission element and which planet carrier is provided with at least one plane wheel which is engaged on one hand with a sun gear and on the other hand with a ring gear, and with a driven-side transmission element. One of the transmission elements has control means for a spring device. There are centrifugal masses corresponding respectively to the driving-side transmission element and to the driven-side transmission element, at least one of which centrifugal masses is connected by means of the spring device to at least one element of the planetary gearset which acts as an intermediate mass, whereby the intermediate mass can be driven in a movement which is a function of the speed and direction of rotation of the two centrifugal masses with respect to one another.

Vibration damper, in particular for motor vehicles, including a work cylinder, a work piston fastened to a piston rod and dividing the work cylinder into two work chambers, possibly an equalization chamber and a piston rod guide which seals the piston rod against the atmosphere, whereby the work chambers are filled with a magnetorheological fluid to which an electric coil can be applied. In the event of a failure or malfunction of the electric coil, it must be possible to achieve a safe damping force, by having at least one permanent magnetic field which acts on the magnetorheological fluid.

A transmission of a motor vehicle can have a friction clutch with a torsional vibration damper and a clutch disc. In the friction clutch there can be a control plate for the control of a friction action as a function of the torsion angle, which control plate can be centered in one direction perpendicular to the axis of rotation by means of at least two diagonally opposite stop edges. The stop edges preferably can interact with two opposite-facing end surfaces of the coil springs within the clutch disc. It can thereby be possible to center the control plate independently of the guide diameter of the hub.

A two-mass flywheel has a first flywheel mass which can be connected to the crankshaft of an internal combustion engine, and can be provided with a thrust bearing for a hub of a second flywheel. The first flywheel can also be designed in its circumferential area with a radial bearing for the hub. The second flywheel can preferably rotate in synchronization with the first flywheel and can also preferably execute a limited rotation relative to the first flywheel. On this flywheel device, the thrust bearing is oriented so that on one hand, a sufficient supply of lubricant to the thrust bearing is always provided, and on the other hand, so that there is an optimal axial guidance of the hub. The invention teaches that this object can be achieved by a thrust bearing with displacement limit stops for the hub provided on both sides of the hub and extending to the radial bearing.

A piston-cylinder unit, in particular a shock absorber, which comprises a cylinder tube in which a piston rod is located so that the piston rod can move axially, is disclosed. The piston rod is guided by a piston rod guide with a seal which closes the cylinder tube, whereby a closing tool beads an edge which projects beyond the piston rod guide. The cylinder tube has an edge in the shape of a truncated cone, which edge encircles the piston rod guide, and which edge is divided into individual truncated cone surfaces by means of partial closing surfaces.
