Definitions
- the invention relates to a brake caliper one
- Disc brake with a thrust bearing comprising a housing having a bore in which a piston is arranged axially displaceable, and a shaft for actuation, which is rotatably mounted and axially displaceable and with a shaft end engages through a housing opening, and two mutually rotatable ramp elements, of which a ramp element rotatably connected to the housing and a ramp member rotatably connected to the shaft, and an adjusting device with a spindle, wherein the adjusting device between the shaft and the piston is present, and an effective between spindle and shaft thrust bearing.
- the caliper comprises a housing with a bore in which a piston for brake actuation
- a shaft is rotatably mounted in the brake housing, wherein the shaft passes through the brake housing and is connected to a ramp element of a ramp arrangement.
- a second associated ramp element is arranged fixed to the housing.
- the shaft transmits this axial displacement on a spindle of an adjusting device, wherein a thrust bearing is provided between the shaft and spindle.
- the axial displacement is transmitted to the piston via the adjusting device. It is a cartridge of
- Adjuster rotatably with the housing fixed
- Polytetrafluoroethylene is provided, in which a lead-copper mixture is incorporated.
- Achsfluchtungscons or
- a complete process step namely a coating process of a support body, can be saved, and that no complex dome shape must be generated. As a result, the production costs are reduced.
- FIG. 1 is an enlarged sectional view of a caliper with adjusting and actuating device according to a first embodiment
- Fig. 2 is approximately scaled exploded view of
- Fig. 3a, b, c enlarged views of the thrust washer.
- a brake caliper 1 of a motor vehicle disc brake includes, inter alia, a housing 2, a piston 3, the
- a shaft 5 is provided, by means of which the piston 3 along a
- Longitudinal axis 9 can be moved via an actuator 10 within the bore 4.
- the shaft 5 engages with a shaft end 6, on which an actuating lever 7 is mounted, through an opening of the housing 2
- Actuator 10 acts on the piston 3 with the interposition of a variable-length adjusting device 20.
- the actuating device 10 comprises a ramp arrangement 11 which includes a housing-fixed ramp element 12 and a
- rotatable ramp element 13 has.
- the ramp element 13 is integrally formed on a disk-shaped end portion 8 of the shaft 5.
- Ramp elements 12,13 are arranged a plurality of rolling elements 14, so that the ramp assembly 10 with mutual rotation of the ramp elements 12,13 a - by an arrow
- symbolized - causes axial displacement of the shaft 5 along the longitudinal axis 9 in the direction of actuation.
- variable-length adjusting device 20 which controls the stroke of the ramp assembly 11 on the piston.
- Adjusting device 20 includes, inter alia, a spindle 21 having an end portion 22 and one on the shaft 23 of the Spindle 21 screwed nut 24, the piston 3
- a thrust bearing 15 is provided in disc-shaped slide bearing design.
- a spring 26 biases the spindle 21 against the thrust bearing 15 via a spring cup 27.
- the spring cup 27 is supported by means flared tabs 28 axially and radially in
- a housing-fixed cartridge 31 surrounds the
- Actuator 10 and the adjusting device 20 according to the invention joined together to form an assembly, which is illustrated in particular in Fig. 2.
- Fig. 2 Here is a pre-assembled summary of the cartridge 31 by a
- the preassembled assembly further includes the ramp assembly 11, the shaft 5, the thrust bearing 15, the spindle 21, the spring 26 and the cartridge 31 and the
- the parking brake function is as follows. at
- Actuation of the parking brake is rotated via the operating lever 7, the shaft 5 and the end portion 8 and the ramp assembly 11 is rotated. This causes the two ramp elements 12 and 13, an axial displacement of the shaft 5 and the end portion 8. This axial displacement is transmitted via the thrust bearing 25 on the end portion 22 and on the spindle 21st Since the spindle 21 is rotatably guided in the cartridge 31 via the toothing 30 of the end portion 22, the spindle 21 performs only an axial displacement without rotation. About the nut 23 screwed onto the shaft 23, the piston 3 is moved axially and actuates the brake pads, not shown, in the direction of not shown brake disc.
- Thrust bearing 15 integrally formed from a homogeneous material matrix.
- the thrust bearing 15 comprises a material component, wherein this material component is a largely homogeneous mixture of several components with different proportions, so that as a result no division into a base or carrier material
- Coating particles takes place.
- a particular advantage of this construction is given by the fact that the separate production of a support body for the thrust bearing 15, and its preparation for a coating, as well as the coating process as such is eliminated, so that a particularly cost-effective production is possible.
- the production can be done, for example, by molding
- the thrust bearing 15 is formed entirely of a non-metallic polymer material which forms the material matrix.
- this can at least partially reinforcing inserts such as a particular
- embedded synthetic fibers filament, yarn or twisted yarn
- fiber sections of carbon, glass or aramid in the composite matrix may be quasi-homogeneous, and thereby an overall composite is achieved.
- the fiber reinforcement is in the form of a tissue.
- the use of carbon fiber is particularly advantageous because the atomic lattice structure has particularly favorable tribological properties of the
- the fibers are at least largely complete
- thermoplastic, tough-resistant polymer material plastic
- plastic tough-resistant polymer material
- PEK polyetheretherketone
- Each thrust bearing 15 is in principle as flat-planar
- Circular disc designed with a diameter D
- At least one of the end faces 35, 36, preferably both end faces 35, 36, of the axial bearing 15 have
- the grooves are 39,40,41 the
- each groove 39,40,41 trapezoidal shaped. Radially outward, the grooves 39,40,41 are rounded with a radius r, so
- a remnant of a gate A may be injection molding
