Definitions
- Vehicle brake system with a motor / pump unit and a unit
- the invention relates to a vehicle brake system which has a motor / pump unit with an electric motor and at least one pump for delivering brake fluid.
- the electric motor has a stator in which a rotor is rotatably arranged.
- the pump is arranged essentially within the rotor and can be driven by it.
- the invention further relates to such a motor / pump unit.
- the motor / pump unit is used to deliver brake fluid to and from wheel brakes of the vehicle brake system in order to actuate or release these wheel brakes.
- vehicle brake systems are also referred to as electrohydraulic brake systems, which can be operated in so-called anti-lock, anti-slip or driving dynamics control mode.
- the motor / pump unit can be arranged directly on a wheel brake of a vehicle or can serve as a central supply element for several wheel brakes.
- a brake system with a vehicle brake actuator in which an electric motor has a stationary stator winding and a rotor rotatably mounted therein.
- the rotor carries several axial pistons, which are supported on an inclined end surface form a swash plate pump with it.
- brake fluid leaks from the axial piston, which flows around the rotor.
- the brake fluid also enters a gap between the stator winding and the rotor, where it leads to a high fluid friction resistance and reduces the magnetic flux between the stator winding and the rotor.
- the electric motor therefore has low dynamics, ie poor start-up and response behavior.
- DE 195 42 654 AI describes an electronically controllable brake system for motor vehicles with a brake pressure transmitter unit and a motor-operated auxiliary pressure source.
- the auxiliary pressure source supplies wheel brakes with hydraulic fluid in addition to or instead of the brake pressure transmitter unit.
- the brake system also has a motor-operated hydraulic pressure source which supports actuation of the brake pressure transmitter unit by a brake pedal or actuates the brake pressure transmitter unit instead of the brake pedal.
- the auxiliary power source and the hydraulic pressure source are driven by the same motor and are in constant communication with it.
- the arrangement of the auxiliary power source, hydraulic pressure source and motor requires a large amount of installation space.
- the object of the invention is to improve a vehicle brake system described above.
- a vehicle brake system with a motor / pump unit which has the above-mentioned features and is developed in such a way that at least one unit is arranged on the motor / pump unit and can be driven with the help of the rotor.
- the arrangement of the motor / pump unit and unit is particularly compact and only a small installation space is required. Due to the compact design, only small masses can be accelerated, so that the motor / pump unit and the additional unit have a good start-up and response behavior. Brake fluid can thus be conveyed in a highly dynamic manner.
- the electric motor and the pump itself are particularly compact in the so-called cartridge design.
- Several pumps can also be surrounded radially by a rotor.
- the object is also achieved with such a motor / pump unit.
- An advantageous embodiment provides that the rotor is in constant gear connection with the unit.
- This connection can e.g. be simply formed over a shaft, so that no complex and error-prone coupling is required.
- the unit is advantageously designed as a pneumatic or hydraulic pump.
- the motor / pump unit thus forms, together with the unit, a compact supply unit that provides all the pressure energy required for a vehicle brake system.
- the unit is a hydraulic unit with a radial piston pump, as is used in known ABS and ASR braking systems.
- brake systems can easily be equipped or retrofitted with a second pressure source.
- stator and at least one section of the rotor facing the stator define an electromagnetic area
- at least the pump defines a hydraulic area
- at least one sealing element is provided which separates the electromagnetic area from the hydraulic area in a fluid-tight manner.
- the sealing element separates the stator and the section of the rotor facing it from the hydraulic region of the pump, in which brake fluid is located.
- the vehicle brake system is advantageously developed such that there is only one air gap between the stator and the rotor.
- the entire rotor is in the hydraulic range. Therefore, the inside of the motor winding is surrounded by a partition that separates it from the hydraulic area and also from the rotor. In the solution according to the invention, however, this partition can be dispensed with. The distance between the stator and the rotor can therefore be made very small.
- the electric motor therefore has an additional increased efficiency and further improved response and start-up behavior.
- stator is fixed in a housing, and the sealing element is annular between the rotor and the housing.
- sealing element is annular between the rotor and the housing.
- a conventional, inexpensive sealing ring can be used as the sealing element, which can be selected from a large assortment and can therefore be matched particularly well to the sealing task to be solved.
- the rotor is supported in the housing such that it can rotate about an axis of rotation by means of two bearings which are arranged on the axial end regions of the rotor.
- the bearings enable the rotor to be guided precisely, and its position can be set independently of the pump.
- the rotor is advantageously essentially cup-shaped and comprises on its bottom a coaxially attached and entrained drive shaft for driving the pump and the unit. Because the cup shape is only open on one side, a closed space for the pump can be sealed particularly easily in such a design in the rotor. For this purpose, for example, a sealing element can be arranged at the opening of the cup-shaped rotor.
- the housing advantageously has an essentially hollow cylindrical housing section which projects radially inwards and coaxially into the cup-shaped rotor, and the sealing element is arranged between the hollow cylindrical housing section and the drive shaft.
- the runner is Sealed ner relatively small area and a sealing element with a small diameter can be used.
- Such sealing elements have a lower frictional resistance and require little space.
- the housing section is arranged between the rotor and the pump, no flow friction occurs between the rotor and the pump.
- the pump is advantageously designed as a gear pump, as a swash plate pump or as a swash plate pump.
- a gear pump as a swash plate pump or as a swash plate pump.
- Such a pump has a drive power which is uniform over time and can therefore be driven by a relatively underpowered electric motor.
- Fig. 1 shows an embodiment of a motor / pump unit according to the invention with a unit partially shown in longitudinal section.
- a motor / pump unit 10 of an anti-lock vehicle brake system comprises an electric motor 12 and a pump 14.
- the electric motor 12 is designed with a hollow cylindrical stator 16 and a rotor 18 arranged therein as a brushless DC motor.
- the rotor 18 is rotated Axis 20 rotatable and its section facing radially the stator 16 has permanent magnets 22.
- the rotor 18 is essentially hollow cylindrical.
- the pump 14 is arranged coaxially to the axis of rotation 20 in this cavity. The pump 14 is driven during operation of the motor / pump unit 10 with the aid of the rotor 18 in order to deliver brake fluid to wheel brakes (not shown) or away from them.
- the rotor 18 is coupled to a unit 23, which borders on the motor / pump unit 10, is part of the vehicle brake system and is used to convey brake fluid.
- the unit can alternatively serve as an auxiliary power source for a hydraulic or pneumatic brake booster.
- the pump of the motor / pump unit can also serve as an auxiliary energy source, in which case the unit delivers brake fluid to or away from the wheel brakes.
- the unit 23 is a radial piston pump with two radially directed, opposite pistons 25 and 27, which can be displaced with the aid of a central eccentric 29.
- the stator 16 and the rotor 18 are surrounded by a gas space 24 (marked with dots) in which there is air.
- This part of the motor / pump unit 10 is referred to as the electromagnetic area.
- the pump 14 is surrounded by a fluid space 26 (marked with wavy lines) which is filled with brake fluid, this part being referred to as the hydraulic area of the motor / pump unit 10.
- An annular sealing element 28 which separates these areas in a fluid-tight manner, is arranged between the electromagnetic and the hydraulic area. Since the electromagnetic If there is no brake fluid in the area, there is no fluid friction between stator 16 and rotor 18.
- the motor / pump unit 10 therefore has a high dynamic. Furthermore, the stator 16 and the rotor 18 cannot be contaminated or damaged by the brake fluid.
- the motor / pump unit 10 is delimited on the outside by a cup-shaped housing part 30 which is rotationally symmetrical with respect to the axis of rotation 20 and which is closed with a housing cover 32 on its left-hand end in the figure.
- a step 34 is axially formed in the housing part 30, on which the stator 16 is supported. The stator 16 is held axially between the step 34 and a collar of a housing part 35 explained later and is supported radially on the housing part 30.
- the cup-shaped housing part 30 has an opening in its ring wall through which a feed line 36 is led into the interior of the housing part 30.
- the passage of the feed line 36 is sealed with an elastomer sleeve 38.
- the stator 16 has a stator winding 40 which is placed around an iron core 42. There is only a thin air gap 44 between the iron core 42 and the permanent magnets 22.
- the rotor 18 has a cup-shaped rotor body 46 which carries the permanent magnets 22 radially on the outside.
- the cup-shaped rotor body 46 is supported at its end section on the right in FIG. 1 by means of a ball bearing 48 which is held in the cup-shaped housing part 30 by a spring ring 50.
- the end section of the cup-shaped rotor body 46 which is axially opposite the ball bearing 48 is connected to the housing by means of a second ball bearing 52 via the housing part 35. sedeckel 32 supported.
- the rotor body 46 is positioned precisely relative to the stator 16. A particularly thin air gap 44 can therefore be formed.
- a drive shaft 54 passes coaxially through a bottom of the cup-shaped rotor body 46 and projects into the cavity formed by the rotor body 46.
- the hollow cylindrical housing section 35 projects into the cavity from the side opposite the bottom of the cup-shaped rotor body 46.
- This housing section 35 is stepped on the end region facing the drive shaft 54 and there carries the annular sealing element 28, which seals off the drive shaft 54.
- the sealing element 28 is pressed into the housing section 35 and has two sealing lips 58 and 60, which bear against the drive shaft 54.
- the sealing element 28 is U-shaped, the opening of the U-shape being directed towards the hydraulic area. The sealing lip 58 is therefore pressed against the drive shaft 54 by hydraulic pressure.
- the pump 14 is received axially next to the sealing element 28 in the housing section 35.
- the pump 14 is designed as a gear pump, conventionally constructed and can be driven with the aid of the drive shaft 54.
- the rotor body 46 is non-rotatably connected to the drive shaft 54 by means of a parallel key 64.
- the pump cover 14 is axially connected to the housing cover 32, which has an extension 82 projecting into the housing section 35.
- the drive shaft 54 protrudes with its end region on the left in FIG. 1 into a bore 70 which is formed coaxially in the projection 82 and in which the drive shaft 54 is slidably mounted.
- the drive shaft 54 on the ball bearing 48 passes through the end wall of the cup-shaped housing part 30 and protrudes into the unit 23.
- the drive shaft 54 is supported there with two bearings 66 and 68. alternative only the bearing 68 or neither of the two bearings 66 and 68 can be provided.
- the eccentric 29 is pressed onto the drive shaft 54 between the bearings 66 and 68.
- a sealing ring 84 is inserted on the outer casing surface facing the housing section 35.
- the housing cover 32 is provided with two connections 86 and 88 in order to connect the motor / pump unit 10 to brake fluid lines, not shown.
- An external thread 90 is formed on the cup-shaped housing part 30, onto which the housing cover 32 is screwed. The housing cover 32 thus closes the fluid space 26 in a fluid-tight manner.
- the rotor 18 rotates relative to the stator 16 and thereby rotates the drive shaft 54.
- the drive shaft 54 drives the pump 14 and the unit 23 in order to convey brake fluid.
- the rotor has a hollow cylindrical rotor body, which is supported at its axial end regions with a bearing in each case in the cup-shaped housing part and in the housing cover.
- annular sealing element is arranged in the cup-shaped housing part and in the housing cover radially outside around the bearings, which sealing element seals between the hollow cylindrical rotor body and the housing part and the housing cover. As described above, this separates the electromagnetic from the hydraulic range.
- the drive shaft can be designed so that it passes through both the housing part and the housing cover and drives a further unit at each of the two protruding sections.
