Definitions
- the invention relates to a device for actuating a wheel brake of a vehicle with the features of the preamble of claim 1. It is provided in addition to an existing hydraulic brake actuation device or also as a brake actuation device available alone.
- a rotating drive movement of the nut or the spindle causes a rotating movement of the planet rollers in the nut around the spindle, which is superimposed on a rotation of the planet rollers about their longitudinal axes.
- the movement of the planetary rollers causes the spindle to move axially with respect to the nut, which is used for brake actuation.
- the known device has the disadvantage that it builds large due to the necessary gear and gear reduction and can therefore not be accommodated in the interior of a rim of a vehicle. Furthermore, the known device is heavy, so that the unsprung mass on the wheel becomes large, which deteriorates the driving characteristics of the vehicle. Another disadvantage of the known device is its high mechanical friction and associated poor efficiency, which requires a relatively powerful drive motor, which increases the space requirement of the known device and its mass and in the case of an electric motor as drive motor means a high current consumption.
- the roller screw drive of the device according to the invention has planetary rollers with a rough profile and a fine profile.
- the rough profiling is carried out, for example, in the form of recesses all round without a slope. It engages in a roughly complementary inner profile of the nut e: n, which also has no slope.
- the coarse profiling causes a form fit in the axial direction between the nut and the planet rollers, there is no axial movement between the nut and planet rollers.
- the part of the roller screw drive of the device according to the invention, referred to as the nut is strictly none Mother, since her profiling is all-round without pitch 5, so there is no thread.
- the planetary rollers engage positively in a spindle profile of the spindle in the axial direction. At least the spindle profile or the fine profile has
- I Q planetary rollers an incline, so it is designed as a thread.
- the device according to the invention has the advantage that its roller screw drive allows a large reduction, so that a Q comparatively weak and therefore small drive motor is sufficient for brake actuation.
- the interposition of a transmission is unnecessary, so that the device according to the invention can be manufactured in a very compact, small and light-weight manner. 5
- the fine profile of the planetary rollers or only the spindle profile is designed as a thread, and the other of these two profiles is designed without a pitch, the fine profile must be offset from planetary roller to planetary roller by the division 0 divided by the number of planetary rollers with respect to the rough profile of the planetary rollers, to enable the planetary rollers to engage both in the nut and on the spindle.
- the fine profile of the planetary rollers and the spindle profile can also be designed as a thread.
- the reduction ratio of the roller screw drive that is to say the ratio of the rotating ones, can be selected by selecting the diameter ratios of planetary rollers to threaded spindle Drive motion for linear movement of the brake actuation vary widely.
- the slope of the fine profile of the planetary rollers and of the spindle profile can be oriented in the same or opposite direction. This allows an arbitrarily large reduction ratio to be achieved.
- the drive motor and roller screw are not necessary. This allows a very light and very compact device for brake actuation to be constructed.
- the drive motor is preferably an electric motor (claim 2).
- the drive motor is preferably an electric motor (claim 2).
- the drive motor can be mounted directly on the spindle or on the nut in order to further reduce the size and weight of the device according to the invention.
- the device 10 for actuating a wheel brake shown in FIG. 1 comprises an electric drive motor 12 and a roller screw drive 14. It is in a two-piece brake caliper 16 installed and presses two brake pads 18 against a brake disc 19, of which only an outer fragment is shown.
- the roller screw drive 14 comprises a so-called nut 20, a threaded spindle 22 located coaxially in the nut 20 and a plurality of planetary rollers 24 which are located in a cylindrical space between the nut 20 and the threaded spindle 22.
- the planet rollers 24 are arranged like planet gears of a planetary gear around the spindle 22 and roll on the threaded spindle 22 when the nut 20 is rotating.
- the planetary rollers 24 are provided with a fine profile 26 in the form of circumferential grooves without a slope.
- the grooves of the fine profile 26 are complementary to a fine thread 28 of the threaded spindle 22, with which they are in engagement. In this way, there is a positive connection in the axial direction between the spindle 22 and the planet rollers 24. Because of the fine thread 28, the spindle 22 moves relative to the planet rollers 24 when they rotate on the spindle 22 as a result of the rotating drive of the nut 20.
- the planetary rollers 24 have a coarse profile 30 in the form of circumferential recesses which are deeper than the fine profile 26 and interrupt the fine profile 26 at intervals.
- the coarse profiling 30 With the coarse profiling 30, the planetary rollers 24 are in engagement with a complementary, coarse inner profiling 32 of the nut 20.
- the coarse inner profiling 32 of the nut 20 is likewise designed to be circumferential without a slope.
- the coarse inner profile 32 is therefore not a thread, the part 20 strictly speaking not a nut. Due to the engagement of the coarse profile 30 of the planetary rollers 24 in the coarse inner profile 32 of the nut 20, there is a positive connection in the axial direction. Since neither the rough profiling 30 of the Planetary rollers 24 still have the rough inner profile 32 of the nut 20 an incline, ⁇ ich move
- Planetary rollers 24 in the axial direction not with respect to the nut 20, even if this is driven in rotation.
- the rotating drive of the nut 20 drives the planetary rollers 24 in a circumferential rolling motion around the spindle 22, whereby they move them in the axial direction.
- the axial displacement of the spindle 22 serves to press one of the two brake pads 18 against the brake disc 19.
- the other brake pad 18 is pressed against the other side of the brake disc 19 via the brake caliper 16 and the disc brake is actuated in this way.
- the disc brake is released again by rotating the nut 20 in the opposite direction. Due to the large reduction of the roller screw drive 14, a relatively low-power drive motor 12 is sufficient to actuate the brake without the interposition of a gear.
- the nut 20 is mounted in the brake caliper 16 with two radial ball bearings 34. Via an axial ball bearing 36, it is supported in the axial direction against the brake caliper 16 when the brake is actuated.
- the nut 20 of the roller screw drive 14 is also the rotor of the electric drive motor 12. Magnetic poles 38 are embedded in its outer circumference. A stator with laminated cores 40 and stator windings 42 is inserted in the brake caliper 16 so that it cannot rotate. The result is a very compact structure of the brake caliper 16, which is not significantly larger than hydraulically operated single-piston brake calipers.
- the device 10 according to the invention can thus be accommodated well in a rim of a vehicle wheel.
- the spindle 22 is located inside a cup into which it merges in one piece on its end face facing away from the brake disc 20.
- the cup forms the rotor 44 of the drive motor 12, it engages around the nut 20 of the
- roller screw drive 14 The magnetic poles 38 of the electric drive motor 12 are embedded in its peripheral wall. Otherwise, the device 43 according to the invention shown in FIG. 2 has the same structure as the device 10 shown in FIG. 1 and functions in the same way. The same reference numerals are used for matching parts. To avoid repetition, reference is made to the corresponding explanations for FIG. 1.
