Definitions
- the invention relates to a drive device for a brake system of a motor vehicle, with a housing, with an electrical machine that has a drive shaft, the drive shaft being connectable or connected to an actuator element of the parking brake by a planetary gear set in the housing, and the drive shaft in is rotatably mounted on a bearing plate arranged in the housing.
- the invention also relates to a brake system for a motor vehicle, with a housing in which an electric machine is arranged, and with an actuator element that can be driven by the electric machine, a planetary gear being interposed between the actuator element and the electric machine.
- the parking brake in particular, is already driven by an electric motor in series vehicles.
- a drive device which has an electric machine, in particular an electric motor, by means of which, for example, a drive spindle of the parking brake is driven to move a brake piston.
- a planetary gear which acts as a transmission gear, is interposed between the electric motor and the brake piston.
- the drive shaft of the electric machine is included in particular connected to the sun gear of the planetary gear and the drive spindle with its planetary gear carrier. To support the shaft, it is rotatably supported, for example by means of a rolling element bearing, in a bearing plate arranged in the housing.
- the drive device according to the invention with the features of claim 1 has the advantage that a highly integral design of the drive device is provided through an advantageous embodiment of the end shield, which ensures all functions in a robust manner in a small installation space, the number of parts of the drive device being reduced and thus assembly - As well as production time can be reduced, with corresponding cost advantages.
- this is achieved in that the bearing plate is made of plastic.
- the bearing plate itself is designed to be inexpensive and weight-saving, and that the bearing plate can be supplemented with further functions or further elements of the drive device with little additional effort.
- the end shield forms a ring gear of the planetary gear.
- the ring gear of the planetary gear is thus integrated directly into the end shield, which also supports the drive shaft of the electrical machine.
- the ring gear can be integrated into the end shield inexpensively during manufacture using simple means.
- the ring gear is thus made of plastic in one piece with the bearing plate.
- the end shield has at least one steel ring, which is overmolded at least in sections by the plastic material of the end shield.
- the steel ring reinforces and stiffens the end shield so that a kind of two-component component is created, which is characterized on the one hand by the low weight of the plastic and on the other hand offers at least some of the robustness familiar from a steel end shield.
- the steel ring particularly preferably has an enlarged edge section which extends over the entire circumference and is encapsulated by the plastic material of the end shield. Because the enlarged edge section is encapsulated, the plastic part of the end shield and the steel ring are positively connected to one another. The plastic material engages behind the edge section of the steel ring, whereby a particularly robust connection is achieved.
- the steel ring preferably has a press-in section which extends over the entire circumference, is free of plastic material and has a cylindrical sleeve-shaped outer surface for contact with the housing. Because the press-in section is free of plastic material, the steel ring as a carrier of the end shield can advantageously be pressed into a corresponding receptacle in the housing, in particular without damaging the plastic material of the end shield. There is thus a kind of separation of the functions, in which the holding force for aligning and holding the bearing plate in the housing is provided by the steel ring, and the ring gear is provided solely by the plastic material.
- the press-in section is formed by the end shield itself and is thus made of plastic. In this respect, the steel ring is dispensed with according to this embodiment.
- the steel ring is preferably completely surrounded by the plastic of the end shield, in particular encapsulated.
- the outside diameter of the press-in section is slightly larger than the inside diameter of a receiving section of the housing for the bearing plate in order to achieve a press fit between the bearing plate or steel ring of the bearing plate and the housing. This also ensures simple assembly of the end shield in the housing.
- the bearing plate has at least one receiving recess and / or at least one receiving projection for arranging a sensor, in particular a rotor position sensor, on the bearing plate.
- the receiving recess and / or the receiving projection is an advantageous form-fitting arrangement of the Rotor position sensor allows on the end shield, whereby a simple assembly and a robust arrangement of the rotor position sensor on the end shield are guaranteed.
- the receiving depressions and / or the receiving projection are particularly preferably designed to receive an annular circuit board of the sensor.
- the sensor or its printed circuit board can be arranged and retained in particular in a form-fitting manner in the receiving recess and / or on the receiving projection. Additional fastening means or arrangement means can therefore be dispensed with.
- the end shield particularly preferably forms a plug connection for a connection contact of the drive device, for example for making electrical contact with the sensor.
- an electrical connection to the electrical machine can be established automatically when the end shield is installed in the drive device.
- the plug-in connection has a sleeve which protrudes axially from the end shield and is formed in one piece with the end shield, preferably has an insertion bevel and into which a connection contact of the electrical machine can be inserted.
- One or more electrical lines which have already been encapsulated by the plastic material of the bearing shield during manufacture of the bearing shield, advantageously lead into the sleeve.
- a printed circuit board is arranged on the portion of the end shield, which carries or has the aforementioned rotor position sensor.
- the circuit board is part of the rotor position sensor, with one or more coils, in particular a receiver coil and a transmitter coil, which are connected in the manner of a resolver in order to determine a rotor angular position of the rotor of the electrical machine.
- Figure 1 shows an advantageous parking brake in a simplified longitudinal section
- FIG. 2 shows a bearing plate of the parking brake in a simplified sectional illustration.
- FIG. 1 shows, in a simplified longitudinal section, an advantageous brake system 1 for a motor vehicle not shown in detail here.
- the brake system 1 has a drive device 2 which is operatively connected to an actuator 3 of the parking brake.
- the actuator 3 has in particular an actuator element 4, in the present case in the form of a brake piston or hydraulic piston, which is axially displaceable by a spindle drive 5.
- a drive spindle 6 of the spindle drive 5, which is designed as a hollow spindle, is connected to a planetary gear carrier 7 of a planetary gear transmission 8.
- the sun gear 10 is non-rotatably connected to a drive shaft 12 of an electrical machine 13 of the drive device 2.
- the drive device 2 also has a housing 14 in which the electrical machine 13 and the planetary gear 8 are arranged.
- a bearing plate 15 is also arranged, which has a first bearing section 16, in which, in the present case, a rolling element bearing 17 is arranged, which is operatively connected to the drive shaft 12.
- an inner ring of the rolling element bearing is connected non-rotatably to the drive shaft 12, while an outer ring of the rolling element bearing 17 is held non-rotatably on the section 16 of the end shield 15.
- the end shield 15 forms the ring gear 11 of the planetary gear transmission 8.
- the ring gear 11 is thus formed integrally in the end shield 15.
- FIG. 2 shows a perspective sectional view of the end shield 15.
- the end shield 15 is essentially made of plastic, whereby in particular the one-piece design of the ring gear 11 with the end shield 15 can be implemented cost-effectively in the manufacture of the end shield.
- the bearing plate 15 forms a step as a result of the change in diameter, which step is designed as an annular disk section 19.
- an annular disk section 20 of the end shield is also formed, which extends radially outward from the ring gear 11.
- a steel ring 21 is assigned to the annular disk section 20 on its outer circumference.
- This steel ring has an L-shaped cross section, with a leg 22 protruding into the annular disk section 20 and being encapsulated or encompassed by the plastic material of the end shield 15.
- the other leg 23 of the L-shaped steel ring 21 extends axially in front of the annular disk section 20, specifically in the direction of the side of the end shield 15 facing away from the sections 18 and 16 of the steel ring 21 free of plastic and forms a press-in section 25 of the end shield 15 on its outer casing 24.
- the outer diameter of the press-in section 25 is slightly larger than the inner diameter of a receiving section 26 of the housing 14 of the drive device 2, so that the bearing plate with the steel ring 21 can be pressed into the housing 14 and, as shown in FIG. 1, is preferably pressed.
- the section 19 is preferably also assigned a rotor position sensor 27, which has an annular circuit board 28 which is inserted in a receiving recess 29 of the section 19 on the side facing away from the ring gear 11, which is coaxially to the annular bearing plate 15 and is thereby held in a form-fitting manner on the end shield 15.
- the circuit board 28 carries a Transmitter coil and a receiver coil, which are operated by a computing unit in order to determine or monitor a rotor angular position of a rotor of the electrical machine 13 by induction.
- the end shield 15 also has a connection device 30, by means of which the rotor position sensor 27 can be electrically contacted.
- the connection device 30 is designed as a plug connection 31 protruding from the section 20, an electrical line 32 being led from the plug connection 31 through the plastic material of the end shield to the section 19 for making electrical contact with the sensor 27.
- the electrical line 32 is already surrounded or overmolded by the plastic material, in particular during the manufacture of the end shield.
- the plug connection 31 has in particular a sleeve protruding axially from the annular disk section 20, which is formed in one piece with the end shield 15 and into which the mating contact or connection contact of the electrical machine can be inserted, in particular when mounting the end shield 15 in the housing 14 to contact the sensor 27 electrically.
- the steel ring 21 is completely surrounded by the plastic material of the end shield 15. It is also conceivable to form the end shield 15 without the steel ring 21, so that the press-in section 25 is made solely by the plastic material of the end shield 15. It is also conceivable to arrange the ring gear 11 as a separate element in the end shield 15, so that it can also be made of a different material than the end shield 15.
