- the clasps are arranged distributed around the circumference over a circumferential angle range of less than 270°, in particular less than 120°.
- the advantage here is that the resulting total force moves the brake pad carrier towards the driver.
- the number of clasps in the brake arrangement is two or three.
- the advantage here is that the resulting total force generated by the clasps has a preferred direction and in this direction moves the brake pad carrier towards the driver.
- the circumferential angle region covered by the respective pocket-shaped recess also has a further, in particular axially spaced, pocket-shaped recess.
- the advantage here is that a pair of recesses can always be attached to the same circumferential position, in particular on the axially front and axially rear end faces of the brake pad carrier.
- the driver is positively connected, in particular by means of a feather key connection, to a shaft, in particular to a rotor shaft, in particular where the driver is plugged onto the shaft.
- a feather key connection to a shaft, in particular to a rotor shaft, in particular where the driver is plugged onto the shaft.
- the brake arrangement has a magnetic body in which a winding is accommodated, in particular wherein the winding is a ring winding which is aligned coaxially with the driver and its axis of rotation, with a ferromagnetic armature disk being arranged axially between the magnetic body and the brake pad carrier, wherein the armature disk is arranged in a rotationally fixed and axially displaceable manner relative to the magnet body, in particular in that bolts protrude through the armature disk and are connected to the magnet body, a braking surface being arranged on the side of the brake lining carrier that is axially remote from the armature disk, wherein spring elements supported on the magnet body press on the armature disk, in particular so that when the winding is not energized, the armature disk is pressed onto the braking surface by the spring elements and when the winding is energized, the armature disk is pulled towards the magnet body, in particular wherein the braking surface is formed on a bearing flange of
- the driver is made of cast iron or steel and/or the brake pad carrier has a material that is softer than the material of the driver, in particular the brake pad carrier has a plastic or a synthetic resin.
- the respective clasp is formed from a round wire by bending, in particular wherein the respective clasp has two legs which are formed at an acute angle to one another, in particular wherein a first support region is connected to a first of the two legs, which is axial Direction protrudes and wherein a second support area is connected to the second leg, which attaches and protrudes against the axial direction on the second leg, in particular wherein the legs extend in the radial direction and the two support areas and are tangentially aligned.
- the advantage here is that bending the round wire can be carried out very easily and inexpensively.
- the bending area which has the acute angle and is arranged between the two legs and is adjacent to the two legs, in particular connecting the two legs, projects into a tooth gap in the external toothing of the Driver in and/or presses.
- the two support areas are aligned anti-parallel to one another.
- the first wire end of the round wire is arranged on the first support area and the second wire end of the round wire is arranged on the end of the second support area facing away from the first wire end in the tangential direction.
- FIG. 1 shows a side view of a brake pad carrier 3 with clips 1 of a first electromagnetically actuated brake according to the invention.
- FIG. 1 An associated longitudinal section is shown in FIG. 1
- the clasp 1 is shown in an oblique view in a first viewing direction.
- FIG. 1 A side view of another lining carrier 3 is shown in FIG.
- FIG. 7 An oblique view belonging to FIG. 7 is shown in FIG.
- the brake lining carrier 3 has internal teeth, which are in engagement with the external teeth of a ring-like driver 4, which is plugged onto a shaft and is positively connected to the shaft by means of a feather key connection.
- the shaft is preferably a rotor shaft of an electric motor.
- the brake pad carrier 3 is arranged to be axially movable relative to the driver 4, since the teeth can move relative to one another.
- a winding is accommodated, when energized a ferromagnetic armature disk, which is non-rotatably connected to the magnetic body and is arranged to be axially movable to the magnetic body, for example Magnetic body is attracted, in particular against the spring elements supported on the magnetic body, which press on the armature disk.
- the spring elements press the armature disk towards the brake lining carrier, so that the latter is then pressed onto a braking surface on its side facing away from the armature disk, which is preferably formed on a bearing flange of the electric motor.
- the clasp 1 is formed from a round wire by bending and has two legs (52, 53) which are formed at an acute angle to one another.
- a first support area 51 which protrudes in the axial direction, is connected to the first leg 52.
- a second support area 50 is connected to the second leg 53, which attaches and protrudes from the second leg 53 in the opposite direction to the axial direction.
- the legs (52, 53) extend primarily in the radial direction.
- the support areas 50 and 51 are essentially tangentially aligned.
- the armature disk is arranged axially between the brake pad carrier and the magnet body.
- the clasp 1 clings to the brake pad carrier 3 due to an elastic pretension, in particular by engaging the support areas 50 and 51 in the pockets 2 recessed on the axial end faces of the brake pad carrier 3.
- the area furthest away from the support areas 50 and 51 presses Clasp radially inwards onto the driver 4.
- a rattling noise that would arise between the brake pad carrier 3 and the driver 4 in the event of speed fluctuations is prevented, since the play between the brake pad carrier 3 and the driver 4 is suppressed by means of the clasp 1 .
- an axial restoring force is generated by means of the clasp, since when the brake pad carrier 3 is axially displaced relative to the driver 4, the clasp 1 is tensioned in the axial direction. Because the clasp 1 presses radially on it Driver 4 and does not lose contact with the driver 4 during the displacement but is connected to the driver 4 by means of static friction.
- the displacement is caused by the spring elements pushing the brake pad carrier towards the braking surface when the winding is not energized.
- the armature disk When energized, the armature disk is retracted, in particular away from the brake pad carrier 3, which can then move free from the braking surface.
- the clasp 1 supports free running through the elastic restoring force it generates.
- the magnetic body is connected in a rotationally fixed manner to the braking surface or to the bearing flange on which the braking surface is formed.
- the two legs (52, 53) When looking axially at the clasp, the two legs (52, 53) have an acute angle to one another, in particular an angle between 10° and 30°.
- the vertical projection of the two legs (52, 53) into a plane whose normal direction is aligned parallel to the axial direction has this acute angle.
- the clasps 1 are arranged distributed over a circumferential angle of less than 270°, in particular less than 240°. In this way, the clasps 1 each press radially, so that the brake pad carrier 3 rests on the driver 4 in the position rotated by 180 ° in the circumferential direction relative to the center of gravity of the clasps 1.
- two clasps 1 are provided at an angular distance of 120° from one another on the circumference of the driver 4.
- three clasps can also be arranged over an angular range of 180 °, so that the brake pad carrier 3 presses on the driver 4 at the position opposite the middle clasp 1.
- the acute angle allows increased stability to be achieved.
- more than three clasps are distributed around the circumference.
- the clasps are distributed over a circumferential angle range of less than 270°, in particular less than 180°.
