The invention relates to a torque transmission device comprising a torque converter, a pump impeller, a turbine wheel and optionally a stator. The inventive device also comprises a converter bypass coupling having a flange (19) which is connected to the housing (6) or the pump impeller (10) in a positively engaged manner. Said flange is arranged between the pump impeller (10) and the turbine wheel (9) and can be connected to the turbine wheel (9) in a frictionally engaged manner by means of a first coupling (27).

A wheel suspension for a motor vehicle includes a support element on the wheel-side rotatably mounting a vehicle wheel and a carrier element on the axle-side, wherein the carrier element on the wheel-side can be adjusted for setting a toe and/or camber angle relative to the support element on the axle-side, wherein the carrier elements on the axle-side and on the wheel-side are coupled to a universal joint in which webs of the carrier elements on the wheel-side and on the axle-side are articulated on a gimbal ring element by means of bearing points. The webs of the support elements are articulated on the gimbal ring element at the bearing points by means of ball joints.

In the hydraulic control device a pressure-reducing valve (MF) is used to produce the belt-tightening pressure for the two pairs of disks (SSA, SSB) of a cone-pulley transmission, while the function of shifting the transmission ratio is performed by a ratio-shifting valve device (DBV 1 3) that adds pressure fluid to one and simultaneously removes pressure fluid from the other of the pairs of conical disks. The pressure-reducing valve and the ratio-shifting valve device work in a cascade arrangement where the assurance of a sufficient belt-tightening pressure takes precedence over the ratio-shifting function.

Control device for continuously variable transmissions

The transmission (2) has two adjustable sheaves (3,4) receiving an endless belt (5). The sheaves are each controlled by a hydraulic adjusting cylinder (6,7). The adjusting cylinders receive pressurised fluid from a pump (14). The fluid pressure and thus the extent of frictional clamping engagement between the sheaves and the belt is regulated by a torque sensor (16).The sensor includes a plenum chamber (27) with an outlet (35) having a variable cross-sectional area which depends on torque variations from the vehicle engine.

The invention relates to a device for modifying the wheel camber of a wheel (1) on a motor vehicle, in which the wheel (1) is pivotally mounted on a wheel carrier (5, 51) by means of a pivot bearing (4, 50). According to the invention, a pivoting plane that is described by the pivot bearing (4, 50) extends in an approximately transversal manner to the central plane (E) of the wheel, the position of a virtual centre of rotation (D) of the pivot bearing (4, 50) lying above the wheel contact plane and on the side of the central plane (E) of the wheel that faces towards the vehicle.

The fluid return circuit(8) from a RPM multiplier(7) and drain circuit(13) from a volume flow regulator(14) open out into a common junction(12) from which continues the return circuit. From the return circuit a charging circuit(39) leads to the suction section of the feed pump(2). At least one cooling and/or lubricating circuit branches from the return circuit. A cooler and/or converter may be installed in the return circuit with the common junction located downstream of it.
