Definitions

• the present invention relates to an assembly, in particular a brake assembly of an electronically controlled vehicle brake system, with an engine having a housing, a hydraulic block and with engine electronics for controlling or regulating the engine.
• Electronically controlled motor vehicle brakes are nowadays not only used to initiate a braking process, such as ABS or ASR (traction control), but also to regulate driving dynamics, such as in the electronic stability program ESP.
• ABS or ASR traction control
• driving dynamics such as in the electronic stability program ESP.
• Increasingly complex electronics are required to control and regulate the motors.
• an ever increasing space requirement on the main board in the controller housing is required.
• heat problems since the motor control is particularly power electronics with high heat radiation.
• the invention is therefore based on the object of providing an assembly with a motor which satisfies such modern requirements.
• the unit should be small and optimized with regard to heat dissipation.
• the engine electronics are accommodated on a side of the engine facing the hydraulic block.
• this offers the possibility of dissipating the heat loss from the electronics directly into the hydraulic block.
• the hydraulic bracket is preferably made of a thermally conductive material, in particular aluminum.
• the engine electronics can also be provided on the side of the engine facing away from the hydraulic block, if this is not otherwise possible for reasons of space.
• the motor electronics are preferably arranged on a separate component, which is, for example, a circuit board and can in particular be a bearing plate of the motor.
• a bearing plate separates the motor from the hydraulic block and can also be used to hold a bearing for mounting the motor shaft.
• the motor electronics are particularly advantageously arranged on the circuit board together with other electronic components, the circuit board itself being provided on the end shield or connected to it.
• one or more speed sensors for monitoring the motor speed can also be arranged on the board.
• a significant advantage of the present invention is achieved if a heat coupling means is provided between the engine and the hydraulic block.
• the heat coupling means is preferably connected directly to the motor electronics and / or the circuit board, so that the heat loss from the electronics can be dissipated into the hydraulic block.
• the heat coupling means also be in direct contact with the block in the assembled state of the engine and hydraulic block.
• the heat coupling means could also be integrally formed with the hydraulic block.
• a modular construction of assemblies of units with different motors can be easily realized.
• an auxiliary electronics arranged in the controller housing takes over the motor control directly. If the power requirement is increased, a motor according to the invention with integrated motor electronics can then be used, so that the other modules do not have to be changed.
• a conventional electric motor (with brushes) as well as a brushless motor can be used.

• the power supply to the motor 2 or its control takes place, for example, via a plug connection 5, which is electrically conductively connected to further electronic components, which can be arranged, for example, in a controller housing (not shown).
• motor electronics 6 are arranged at least partially within a housing 7 of the motor 2. There is thus a shift of the motor electronics 6 from the previously common controller housing (not shown) at least partially into the housing 7, in which the installation space required for the motor electronics 6 is rather available.
• the motor electronics 6 are preferably provided on a side of the motor 2 facing the hydraulic block 4. In particular, this offers the possibility of dissipating the heat loss from the electronics 6 directly into the hydraulic block 4.

• a heat coupling means 8 is particularly advantageously provided directly on the motor electronics 6 and / or a circuit board 10 for dissipating the heat into the hydraulic block 4. Due to the special thermal conductivity properties, it is particularly advantageous if the hydraulic block 4 is made of aluminum. However, it should also have good thermal conductivity with another material.
