Definitions
- the invention relates to a brake system, in particular with a disc brake in the form of a floating caliper, for a motor vehicle according to claim 1.
- an electromechanical brake system in which an electric motor that is reversible in its direction of rotation with a shaft that is axially adjustable via a screw thread presses the brake lining against a brake disk or lifts it off;
- the brake lining is mounted for a pivoting movement about an axis parallel to the side surface of the brake disc and laterally spaced from this surface, which is essentially at right angles to an axis tangential to the outer circumference and in the plane of the brake disc Line is arranged so that the frictional force between the brake pad and the brake disc has a complementary component to the force applied by the electric motor to press the brake pads against the brake disc.
- the invention has for its object to provide an electromechanically actuated brake system, in particular with a disc brake in the form of a floating caliper, for a motor vehicle, which compared to known solutions with sufficient dimensioning in terms of clamping force and response time by greater compactness and greater stroke -Distinguishes travel path that enables direct wear compensation without a separate adjustment device.
- the axial diameter of the threaded spindle which can be enlarged thereby, means that large axial travel paths without the risk of kinking the axial lifting means and the transmission of high displacement Actuating forces possible, whereby a self-reinforcing additional lever transmission and a separate adjusting device are unnecessary.
- the outside diameter of the threaded spindle is at least in the order of magnitude of the outside diameter of the motor drive shaft or the rotor shaft.
- 1 shows an axial section of a first embodiment with an electric motor arranged axially aligned behind the spindle drive; 2 shows an axial section of a second embodiment with an electric motor arranged parallel to the spindle drive and coupled via a gear.
- a brake caliper 1 each show a brake system for a wheel of a motor vehicle in a so-called floating caliper version;
- a brake caliper 1 the same force is exerted by a brake piston 2 on one first brake pad 1.3, which is arranged here on the right in front of a brake disk 1.1, as on the second brake pad 1.2, which is arranged here on the left in front of the brake disk 1.1.
- the housing of an electromechanical brake actuator which optionally also — as in the case of the exemplary embodiment according to FIG.
- the spindle drive 2-4 is axially offset with respect to the electric motor 5; by the electric motor
- axially fixed threaded spindle 3 drives at the free end of the motor drive shaft 6 the coaxially overlapping spindle nut, which is designed as part of the brake caliper 2, with an axial stroke; the brake caliper 2 or the spindle nut integrated therewith are relative to the brake pads 1.2; 1.3 secured against rotation, in particular by a positive wedge 2.1.
- a roller drive 2-4 is preferably provided, in which the threaded spindle 3 triggers the stroke movement of the spindle nut and thus of the brake piston 2 via coaxial rollers 4.
- the electric motor 5 is axially aligned behind the spindle drive 2-4, so that the rotor shaft 5.1 of the electric motor 5 forms the motor drive shaft 6, which is designed as a threaded spindle 3 at its left end.
- the electric motor 5 is arranged parallel to the spindle drive 2-4, the rotor shaft 5.1 via a spur gear reduction gear 9 - here in the form of a toothed belt drive - is coupled to the motor drive shaft 6, which in turn at its left free end as a threaded spindle 3 is trained.
- a spur gear reduction gear 9 - here in the form of a toothed belt drive - is coupled to the motor drive shaft 6, which in turn at its left free end as a threaded spindle 3 is trained.
- the toothed belt drive provided here for coupling between the motor drive shaft 6 and the rotor shaft 5.1, it is also possible, for example, to use a pure gear transmission.
- the mutually parallel arrangement of the electric motor and spindle drive advantageously shortens the axial overall length of the overall assembly on the one hand, and on the other hand the spindle pitch of the spindle transmission can be increased in the sense of a greater maximum load capacity of the spindle drive.
- the motor drive shaft 6 is only supported in a central bearing 8, preferably at the end facing away from the threaded spindle 3, with an additional radial support on the spindle-side end via the rollers 4 the spindle nut or the brake caliper 2 can take place, which in turn is supported in the brake caliper 1.
- connection can be provided via a coupling between these, then non-one-piece, components, in particular in the sense of greater flexibility for production and service.
