Definitions
- the invention relates to an electromechanical disc brake with a parking brake actuator for motor vehicles. Parking brake actuators are used to prevent a vehicle from rolling away from a standstill.
- a brake cylinder assigned to the disc brake is usually equipped with a mechanically actuated parking brake function.
- the principle of the parking brake function used in a conventional disc brake cannot be used.
- EP2650557A1 Another solution is proposed by EP2650557A1 with a locking lug on a cam.
- This actuation principle is linked to the actuation of the disc brake by means of the cam disc and cannot be used for other actuating mechanisms.
- the locking nose is fixed and part of the application mechanism.
- the locking lug is attached at the point of maximum tightening.
- DE10138494A1 discloses ei ne solution in which a rotor disk or a motor shaft blocked, which is connected to a screw gear. This so-called locking device is a bistable magnetic brake. Due to the direct connection to the transmission, greater forces act on the locking bolt and the locking device is not integrated as an additional component in the electromechanical brake actuator.
- EP1686029A1 also describes the locking or braking of a rotor of an electric motor via a brake lining in order to implement a parking brake actuator.
- a bolt is used for locking, which is driven by an electric motor.
- the object of the invention is to provide an electromechanical disc brake se with a parking brake actuator, which is inexpensive and has a small footprint.
- an electromechanical disc brake has a parking brake actuator designed as an electromagnetic linear drive and an electric motor can be locked with the electromechanical linear drive.
- the invention turns the main actuation branch of the electromechanical disc brake and adds a linear drive to it.
- the main actuation branch is to be understood as the electric motor and an actuator, which are used to clamp a brake disc over two brake pads.
- the electric motor is locked in the set position.
- the electromechanical disc brake maintains the set braking force without supplying additional holding energy to hold the electric motor in the set position. That is, the electromechanical disc brake is finally held by the form-fitting connection between the electric motor and the linear drive introduced by the lock.
- the linear drive has a plunger and a rotor of the electric motor has locking grooves.
- the plunger engages in the locking grooves of the rotor to produce a form-fitting connection while the electric motor is locked.
- the locking grooves are advantageously arranged on the rotor at regular intervals along the circumference of the rotor. The more locking grooves the rotor has, the more positions there are for locking the electric motor.
- the linear drive is designed as a lifting magnet.
- Lifting magnets are electromagnetic actuators that exert a force on the plunger, also called plunger core, by means of an electrically generated magnetic field, so that the plunger can be moved linearly in two directions.
- An electric magnetic field is generated via a coil mounted around the plunger.
- the plunger is held in a starting position or the plunger plunges positively into a locking groove in the rotor and locks the electric motor in the set position.
- the starting position is defined as the position of the ram at which the The plunger is not immersed in a locking groove in the rotor. The rotor can therefore turn completely.
- the linear drive is arranged radially, in the direction of the locking grooves, in an electric motor housing of the electromechanical disc brake.
- the linear drive is therefore integrated in the electromechanical disc brake. More precisely, the linear drive is arranged axially between a control unit of the electromechanical disc brake and a cam of the electromechanical disc brake and radially in the direction of the rotor.
- the electric motor is formed as an external rotor, the locking grooves being arranged on the rotor in a form-fitting manner in the radial direction.
- Electric motors have a stator and a rotor.
- An external rotor is an electric motor in which the stator, i.e. the stationary part, is located inside the electric motor and the rotor, i.e. the moving part, encloses the stator.
- a lateral surface of the external rotor is directly accessible and primarily does not fulfill any electromagnetic function
- the linear drive is connected to a motor control device via a cable connection for the electrical control of the linear drive.
- the engine control device is designed to control the electric motor and is advantageously arranged within the electric motor.
- the motor control device is arranged axially in the direction of the cam disk behind the linear drive, so that a short cable connection is sufficient for the electrical connection of the linear drive.
- there is no additional control unit for control of the linear drive is necessary, thereby reducing the cost of the electromechanical disc brake.
- the linear drive is advantageously arranged axially parallel to an electric motor axis, in the direction of the locking grooves, in the electric motor housing of the electromechanical disc brake.
- the linear drive is embedded directly in the electric motor between the control unit and the rotor. The additional installation space in a vehicle with the integration of the linear drive can be used for other purposes.
- the linear drive is also better protected, since the linear drive is not arranged on the electric motor, but in the electric motor.
- the electric motor is also designed as an external rotor in a further embodiment.
- the locking grooves are arranged in a form-fitting manner on the rotor in an axially parallel direction.
- the mode of operation is the same as in the first embodiment, in which the linear drive engages radially in the locking grooves of the Ro sector.
- the linear drive is connected directly to the motor control unit.
- an additional external cable connection i.e. a cable connection arranged outside the electric motor housing.
- the motor control device for the alternative linear drive has a base plate, the base plate being at least in sections a part of the electric motor housing.
- the base plate ensures a hermetic seal for the motor control unit
- the base plate of the motor control unit integrates the lifting magnet, which is designed as a linear drive, as a locking device.
- the integration of the linear drive is particularly achieved by the fact that the coil of the lifting magnet is inserted from the motor side, that is to say the side on which the electric motor is flanged to the cam disc, during production.
- the base plate of the alternative linear drive has bores for passing through a connecting line.
- the holes are still filled with a thermoplastic compound to seal the spaces in the holes.
- the space of the bores that is not filled by connecting lines is to be regarded as free space.
- the drill holes and the coil of the electric motor which is at least partially arranged in the motor control unit, are encapsulated with the thermoplastic compound in a further embodiment.
- a transmission of the electromechanical disc brake's for converting the rotating movement of the electric motor into a translational movement, has a cam on a disc.
- the electromechanical disc brake is designed as a sliding caliper disc brake.
- FIG. 2 is a sectional side view of an electromechanical actuator according to FIG. 1 with a parking brake actuator designed as a linear drive and integrated according to a first embodiment.
- FIG. 3 is a sectional side view of the electromechanical actuator according to FIG. 1 with a parking brake actuator designed as a linear drive and integrated according to a second embodiment.

- the disc brake 1 is designed as a sliding caliper disc brake.
- a saddle 21 is mounted axially on a brake carrier 23 sliding tend via two plain bearings 22, 22a.
- An electromechanical actuator 20 clamps a brake disc 32 by means of a rim-side brake lining 25 and an application-side brake lining 25a.

- the electromechanical actuator 20 has an electric motor 2 axially along an electric motor axis AEM.
- the electric motor 2 is axially connected to a cam disk 18 via a shaft 26.
- the cam 18 is, starting from the electric motor axis AEM, arranged radially in the electromechanical actuator 20 African.
- the cam 18, which is operatively connected to the electric motor 2 is designed to convert a drive torque, that is to say a rotating movement of the electric motor 2 about the electric motor axis AEM, into a translational movement, that is to say a linear movement, for actuating a brake tappet 27. walk.
- the brake tappet 27 is used to actuate a rotary lever, not shown, to clamp the brake disk 32.
- the electric motor 2 also includes a gear 5 arranged axially along the electric motor axis AEM for applying a desired drive torque.
- a motor control unit 13 for regulating the actuator 20 is arranged in the electromotor housing 15 radially above the transmission 5. The engine control device 13 is therefore integrated in the electric motor 2 in a space-saving manner.
- a rotor 3 with locking grooves 10 verse is arranged in the electric motor 2. During an adjusting movement of the electromechanical actuator 20, the rotor 3 rotates about the electric motor axis AEM.
- the locking grooves 10 are arranged ent long a lateral surface 30 of the rotor 3 at regular intervals.
- the rotor 3 around includes an electromagnetic stator 29, hereinafter referred to as stator 29, of the electric motor 2.
- stator 29 In contrast to the stator 29, the rotor 3 predominantly does not perform an electromagnetic function, whereby the locking grooves 10 are arranged directly on the lateral surface 30 of the rotor 3 .
