Abstract: The invention relates to an external stator of a rotating-field machine with internal rotor, which external stator is designed as an internal stator or external stator and which external stator has a number of N stator teeth which together form a number of N/2 tooth groups, and each stator tooth has in each case one pole core and one pole shoe integrally formed thereon, wherein the pole cores are manufactured from a first material, and that in each case one tooth group is formed by two directly adjacently arranged stator teeth which, together with a magnetic return means, are constituent parts of a magnetic circuit, characterized in that, between two adjacent stator teeth of two adjacent tooth groups, there is arranged in each case at least one intermediate element which extends in particular in an axial direction of the stator and which is manufactured from a second material, and in that differs from the first material of the pole cores.
Abstract: A brake apparatus, for electrically driven motor vehicles, includes a traction motor at an axle of a vehicle, which traction motor is used both as drive motor and as brake system with recuperation of brake energy, a first piston-cylinder unit, which is actuatable by means of an actuating device, in particular brake pedal, a second piston-cylinder unit, which is actuatable by means of an electromotive drive and a non-hydraulic gearing apparatus, in particular spindle drive. The piston-cylinder units are connected via hydraulic connecting lines to wheel brakes of the motor vehicle. A pressure chamber of the first piston-cylinder unit is connected to two wheel brakes of a vehicle axle, and a pressure chamber of the second piston-cylinder unit is connected to a vehicle axle for active brake force feedback control and recuperation control in interaction with the traction motor.

Abstract: A shift gearbox may include at least two driven piston-cylinder units, which are each driven via a transmission of a drive, and the piston-cylinder units may each comprise a piston, which delimits a working chamber, and each working chamber is in hydraulic connection with at least one clutch actuator and at least one gear selector via a hydraulic main line, whereby the clutch actuator comprises a working chamber delimited by a piston. A valve may be respectively arranged between each working chamber of a clutch actuator and a hydraulic main line, and both the pressure build-up and the pressure reduction in the clutch actuators may occur by adjusting the piston of a piston-cylinder unit.

Abstract: The invention relates to a drive system for a vehicle, having a drive or electromotor, a crankshaft and a transmission, in particular a hub transmission. It is provided according to the invention that the transmission (10) is arranged in the central region of the vehicle, in particular the region of the crankshaft (1) and in particular is integrated and the crankshaft rotational speed is transmitted.
Abstract: The invention relates to a variable electrohydraulic valve controller, comprising a piston, which is arranged in such a way that the piston acts on a valve, particularly a gas exchange valve of an internal combustion engine, in order to actuate said valve, a valve hydraulic chamber bounded by said piston, and at least one piston-cylinder unit, which is connected to the valve hydraulic chamber by means of a hydraulic line in which a switching valve is arranged. According to the invention, the piston (14) of the piston-cylinder unit (14, 15) is driven by a drive. particularly a motor.
