Definitions
- the invention relates to an electric motor / pump unit with a shaft that carries both the armature of the electric motor and the eccentric of the pump, the shaft in two pump bearings, which are arranged in the pump housing, and a third bearing that is held in the motor housing is carried, and with fastening means to fasten the housing of the electric motor to the pump housing.
- Such a motor / pump unit is e.g. described in DE 43 15 826 AI. According to the description, it is used in a hydraulic brake system.
- the pump housing consists of a one-piece block in which, in addition to the pump pistons, valves are also provided, with the aid of which pressure modulation can take place in the wheel brakes of the brake system.
- the block has a three-stage blind hole into which the motor shaft protrudes. In the second stage of the blind bore, holes open vertically in which the pump pistons are guided. The first and third stages serve to accommodate the pump bearings.
- the fastening means be designed in such a way that the electric motor housing can be aligned with the pump housing before the final assembly.
- the shield consists of a plastic cap that is inserted into the cup-shaped motor housing and therefore can no longer be moved radially with respect to the electric motor.
- This shield has on its outer end face a recess delimited by a ring, in which the first pump bearing is inserted over a partial length and is held captive. Before the electric motor is mounted on the pump housing, the shaft is thus held by the motor bearing and by the first pump bearing.
- the shaft is inserted into the pump housing, the first pump bearing being inserted with a precise fit in the first receptacle in the pump housing. The forces occurring during operation are then no longer absorbed by the end shield but by the pump housing.
- the mounting of the first pump bearing in the end shield of the electric motor be carried out with play. This play is selected so that the holding forces are still sufficiently large to hold the bearing velier-proof before assembly, on the other hand to allow displacement of the end shield and thus of the entire electric motor housing with respect to the first pump bearing fixed in the pump housing.
- the motor-pump assembly consists of an electric motor 1 and a pump 2.
- the pump consists of a pump housing 3, which in this exemplary embodiment is formed from an aluminum block.
- a three-stage blind bore 4 extends.
- the first stage 5 with the largest diameter carries a first pump bearing 6, in the second stage 7 with a somewhat smaller diameter, holes open laterally, which the Guide the pump piston 8.9.
- a second pump bearing 11 is held in the deepest stage 10 with the smallest diameter.
- the electric motor 1 consists of a deep-drawn pot-shaped housing 20 that is open towards the pump housing 3. This side is closed by a bearing plate 21 which is inserted into the open side of the housing 20 in such a way that it no longer has any radial mobility.
- the bearing plate 21 also serves as a support plate for the brushes 22, with feed lines 23 to the brushes being embedded in the bearing plate 21 made of plastic.
- the bottom of the housing 20 has a depression located in the center, which carries a further bearing, namely the motor bearing 25.
- the shaft 30 carries both the armature 26 of the motor and an eccentric 31 which is located in the pump housing 3 at the level of the second stage 7 after the electric motor has been mounted on the pump housing 3.
- the commutator 27 is also located on the shaft 30.
- the permanent magnets 28 of the electric motor are fastened to the inner wall of the cup-shaped housing 20.
- the figure shows the motor-pump unit in the assembled state.
- the shaft 30 is supported by the two pump bearings 6, 11, which introduce the radial forces into the pump housing 3 when the pump 2 is operating.
- the first pump bearing 6 Before assembly, the first pump bearing 6 is held on the outer side of the end shield 21, this bearing and the motor bearing 25 holding the shaft 30.
- the first pump bearing is held by a ring 32 formed on the end plate 21, in which the outer ring of the first pump bearing is inserted over a short partial length.
- This holder is designed in such a way that the pump bearing was held captively.
- the outer diameter of the outer ring of the first pump bearing 6 has previously been chosen to be the same size as the inner diameter of the ring 32.
- the housing 20 of the electric motor 1 was also aligned with the pump housing after assembly, in which the first pump bearing 6 was fixed in the pump housing.
