摘要： The invention relates to a method for producing a bush body (14), in particular from a ceramic material, wherein the bush body (14) has an opening (12) and an outer surface (18). The bush body (14) is made from ceramic material in the form of a tube (32). For wall thickness to height ratio of ca. ≥ 1 : 4 to 1 : 5, the bush body (14) is produced by extrusion, for a wall thickness to height ratio of ca. ≤ 1 : 4 to 1 : 5 the bush body (14) is produced by dry pressing. The outer surface (18) is provided with a positive profiling (30, 42, 44, 48, 78, 88, 98) or a roughening (48, 62) or a negative profiling (52). For long bushes isostatic presses are preferably also used.

摘要： The invention relates to a circuit assembly for a motor vehicle. The circuit assembly comprises an electric motor. The electric motor comprises a control unit, wherein the control unit is designed to actuate the electric motor, in particular a stator of the electric motor, for rotating the rotor. According to the invention, the circuit assembly comprises a controllable switch with a control connection. The controllable switch is connected, in particular in a separable manner, on the input side to a battery potential of an on-board power supply system of the motor vehicle. The controllable switch is connected on the output side to the electric load, in particular the electric motor, preferably to the control unit of the electric motor. The control unit has a control input for receiving an activation signal for activating the load, in particular in the case of an electric motor for rotating a rotor of the electric motor. The control unit is connected to the control connection of the controllable switch and designed to apply a switch signal to the control connection to activate the load depending on the activation signal.
