Definitions
- the invention relates to a braking device according to the type of the main claim.
- Such a braking device is known from EP 0 520 525 B1.
- the known braking device has an electric motor which both actuates and releases a friction brake via a gear transmission.
- This has the disadvantage that in the event of failure of the electric motor or its power supply, the friction brake does not, at least not completely, release. H. at least a considerable residual braking force acts on a vehicle wheel. This results in a yaw moment, that is to say an effective torque on the vehicle about its vertical axis, which impairs the driving stability of the vehicle.
- the level of the yaw moment depends not only on the residual braking force but also on the coefficient of friction between the vehicle wheel and the road and consequently changes with the road condition. If the coefficient of friction is low or if the coefficient of friction changes suddenly, the vehicle wheel tends to lock. If the affected vehicle wheel is a front wheel, then the steerability of the vehicle is restricted. Furthermore, a braked vehicle wheel can cause the vehicle to skid when cornering, and a blocked driving wheel with high probability triggers a skid of the vehicle.
- the braking device according to the invention with the features of the main claim has a second electric motor for releasing the friction brake.
- This has the advantage, in particular if both electric motors are connected to independent power supplies, that the friction brake can be completely released even in the event of a fault, which means a failure of one of the two electric motors or its power supply. H. there is no longer any residual braking force, and a vehicle wheel that can be braked with the braking device according to the invention is freely rotatable. Steerability and driving stability of the vehicle are fully guaranteed even in the event of a fault.
- Another advantage of the invention is that, in the event of a fault, at least one partial braking force can be applied with the remaining electric motor; the braking device does not fail completely.
- the power and torque of the two electric motors can be designed so that only the first one generates a maximum braking force that is sufficient to block a vehicle wheel, for example.
- the second electric motor can be designed weaker because it is only needed to release the friction brake.
- Both can also Electric motors are designed so that the maximum braking force can be generated with each of them (claim 3). This has the advantage that the brake device remains fully functional even if an electric motor fails.
- the two electric motors can also be designed so that each only applies approximately half the maximum braking force (claim 4). To generate the maximum braking force, both electric motors must therefore be switched on. The necessary installation space and weight of the braking device according to the invention can thereby be reduced. Another advantage is that the friction brake can still be operated in the event of a fault, even if not with maximum braking force.
- the braking device has a return travel sensor for determining the return travel of brake linings when the friction brake is released and thus the gap between the brake lining and brake disk or drum.
- the return path can be set to a constant value regardless of the wear on the brake pads, i.e. a defined clearance between the brake pad and the brake disc or drum.
- This provides a gain in dynamics thanks to the consistently short actuation travel and the consistently short response time when the friction brake is actuated until the first grip, even with increasing wear on your brake pads.
- all wheel brakes of a vehicle apply simultaneously and thus from the start of braking with an even distribution of braking force on the vehicle, even if the brake pads are worn to different extents. The vehicle is not brought out of its lane by a wheel brake acting earlier.
- An additional advantage of this embodiment of the invention is that the defined clearance adjustment is accomplished without complex mechanics.
- self-locking gear is meant a gear that allows movement by applying force or torque only when the applied force or torque exceeds a threshold.
- Self-locking gears are, for example, gear or planetary gears.
- the invention is explained in more detail below with reference to an embodiment shown in the drawing.
- the single figure shows a section of a braking device according to the invention.
- the brake device according to the invention shown in the drawing has a Faust brake caliper 12 with a pair of brake pads 14 for braking a brake disk 16, of which only a fragment is shown in the drawing.
- REPLACEMENT BUTT (RULE 26) Brake linings 14 against the brake disc 16 are installed in the brake caliper 12 with a spindle gear with a threaded spindle 18 and a spindle nut 20.
- the threaded spindle 18 presses against one of the two brake pads 14 and a reaction force presses the other brake pad 14 against the opposite side of the brake disk 16 in a manner known per se via the brake caliper 12.
- the spindle nut 20 is rotatably supported by two radial ball bearings 22 in the brake caliper 12 and in a cover 24 connected to the brake caliper 12, for example by screwing. It supports itself when the brake pads 14 are pressed against the brake disc 16 via an axial ball bearing 26 against the cover 24.
- the spindle nut 20 has a ring gear 28 which is integral with it and with which a first gear 30 meshes for rotating the spindle nut 20.
- the first toothed wheel 30 is mounted in a rotationally fixed manner on a shaft 32 of an electric reset motor 34.
- a second gear 36 meshes with the first gear 30, which is mounted on a shaft 38 of an electric brake actuation motor 40. Both electric motors 34, 40 are flanged to the cover 24 of the brake caliper 12.
- the two gear wheels 30, 36 are located in a cavity 42 between the cover 24 and the brake caliper 12.
- the shafts 32, 38 of the electric motors 34, 40 are arranged parallel to the threaded spindle 18 and are in one plane with the latter, i. H. the actuating motor 40 is located radially outside the resetting motor 34 with respect to the threaded spindle 18.
- the second gear 36 of the actuating motor 40 can also be located at a different location on the circumference
- REPLACEMENT BUTT (RULE 26) engage the first gear 30 of the return motor 34 or mesh at any circumferential point with the ring gear 28 of the spindle nut 20, so that the two electric motors 34, 40 are not in one plane 40 with the threaded spindle 18 and the actuating motor 40 has a smaller distance from the threaded spindle 18 .
- the two electric motors 34, 40 can also drive the spindle nut 20 via an angular gear, not shown.
- the braking device 10 has a rotation angle measuring device 44 on the shaft 32 of the return motor 34. With it, the total gap between the two brake pads 14 and the brake disc 16 with the friction brake 14, 16 released, the so-called air gap, can be determined and adjusted. Since the shaft 32 of the reset motor 34 is connected via the first gear 30, the ring gear 28 of the spindle nut 20, the spindle nut 20 and the threaded spindle 18 to the brake pad 14 actuated by the threaded spindle 18, the angle of rotation of the shaft 32 of the reset motor 34 is a feed path the brake pads 14 to the brake disc 16 and a remind ⁇ tellweg away from the brake disc 16 proportional.
- rotation angle sensors 44 for example, inductive, capacitive or optical measuring devices come into consideration, as are known per se in a large number of embodiments. It is advantageous to use an electronically controlled reset motor 34, the electronic commutation of which enables the reset motor 34 to be rotated in a defined manner.
- the function of the braking device 10 according to the invention is as follows: To actuate the braking device 10, the
- Actuator motor 40 is switched on and drives the spindle nut 20 via the second and the first gearwheels 36, 30.
- the spindle nut 20 uses the threaded spindle 18 to convert the rotational movement into a displacement movement which presses the brake pad 14 shown on the right in the drawing against the brake disc 16.
- the brake caliper 12 designed as a floating caliper presses the brake lining 14 shown in the drawing on the left against the other side of the brake disk 16 in a manner known per se.
- the reset motor 34 is switched on, which rotates the spindle nut 20 in the opposite direction via the first gear 30 and thereby releases the friction brake 14, 16 again.
- the angle of rotation measuring device 44 determines the angle of rotation of the resetting motor 34 when the friction brake is released, which is proportional to the return path of the brake linings 14. The rotation angle measuring device 44 thus forms one
- the return motor 34 is switched off after rotation by a fixed angle, which is usually more than one revolution.
- a defined clearance of approx. 0.1 mm - 0.2 mm is achieved regardless of the wear of the brake pads 14 and the wear of the brake disc 16.
- a residual braking force after releasing the braking device 10 is zero, so that when the braking device 10 is released, the brake pads 14 are not worn out, the braking device 10 is not additionally heated, and driving stability of a vehicle is not impaired.
- the two electric motors 34, 40 with the two gears 30, 36 and the spindle gear 18, 20 form a locking gear. This means that the friction brake 14, 16 does not release automatically after the actuating motor 40 is switched off, but only by resetting with the resetting motor 34
- Another advantage of the braking device according to the invention is its usability as a parking brake: For this purpose, the braking device 10 is actuated with the actuating motor 40 and the current is then switched off. The brake device 10 remains actuated. Any locking means are not required. A worm gear (not shown) can also be used as the locking gear instead of the spindle gear 18, 20 used in the exemplary embodiment.
- a self-locking gearbox can also be used instead of a C. Locking gear come into consideration.
- Self-locking means that the gear on its output shaft can only be moved by overcoming a certain threshold torque.
- Self-locking gears can be, for example, toothed or planetary gears. These increase a torque required for rotating n the currentless electric motor by their reduction factor at the output 1 hurry. Added to this is the internal friction of the self-locking transmission. A determined braking force is therefore also maintained with a self-inhibiting transmission in the case of non-energized electric motors.
