Abstract
A motor-pump unit of a motor vehicle anti-lock brack device may be simply sealed off from moisture with end-surface application of a motor housing (1), and/or an electronic housing (3), in front of and/or behind a pump housing (2). Connecting lines (6.1; 6.2) between a brush plate (1.2) in the motor housing (1) and a circuit board (3.1) in the electronic housing (3) are laid within the motor housing (1) and pump housing (2) through lead-throughs in the adjoining end surfaces rather than being laid on the outside over the pump housing (2). These surfaces rest against each other and are sealed-off from each other by circumferential packings (9; 9.1) arranged radially towards the outside.
Claims21
A motor-pump unit, comprising:
- a pump housing including a first end surface and a second end surface;
- a motor housing including an end surface located in front of the first end surface of the pump housing;
- an electronic housing including an end surface located in front of the second end surface of the pump housing;
- and
- electrical connecting lines extending through the end surfaces of the pump housing, motor housing and electronic housing and extending through the pump housing between an inside of the motor housing and an inside of the electronic housing.
A motor-pump unit included in a motor vehicle anti-lock device, comprising:
- a pump housing including a first end surface and a second end surface;
- a motor housing including an end surface located in front of the first end surface of the pump housing;
- an electronic housing including an end surface located in front of the second end surface of the pump housing;
- and
- electrical connecting lines including at least one of electric supply lines and control lines extending through the end surfaces of the pump housing, motor housing and electronic housing and extending through the pump housing between an inside of the motor housing and an inside of the electronic housing;
- wherein the end surfaces of the pump housing, motor housing and electronic housing which lie one in front of the other are sealed-off from each other radially towards an outside direction by interposed circumferential packings;
- wherein the electrical connecting lines extend radially within the circumferential packings through the end surfaces located one in front of the other of the motor housing and the pump housing as well as of the pump housing and the electronic housing;
- wherein the electrical connecting lines are provided in axial spacers within the motor housing, the spacers being fixed between tangentially opposite end sides of magnetic shells held on an inner circumference of the motor housing;
- wherein the spacers which receive the connecting lines are extended or developed in a plug connection manner which extends through the pump housing and can be contacted in the electronic housing by an electrical or electronic supply device;
- and
- wherein the electrical connecting lines connect a brush plate in the motor housing to a circuit board in the electronic housing.
