Disc brake, disc brake system, and parking brake system

#This application is a national stage of International Application No. PCT/DE2018/100617, filed Jul. 5, 2018, the disclosure of which is incorporated herein by reference in its entirety, and which claimed priority to German Patent Application No. 102017116323.9, filed Jul. 14, 2017, the disclosure of which is incorporated herein by reference in its entirety.

#The invention relates to a disc brake having a brake carrier, a brake caliper, brake shoes, and an actuating piston. The invention further relates to a disc brake system and a parking brake system.

#A disc brake of the type discussed here is known from WO 99/05011 A1, in which it is used as a vehicle brake. A brake carrier, a brake caliper, brake shoes, and an actuating piston are provided in the disc brake. The brake carrier has at least one mounting point for mounting on a vehicle. The brake caliper is guided on the brake carrier and forms a receiving space for a brake disc, the receiving space having two brake sides with regard to the brake disc. The brake shoes are associated with the brake sides and are supported on the brake carrier against braking forces. The actuating piston in the direction of its longitudinal axis is displaceably accommodated on the brake caliper, and can be actuated hydraulically or by means of an electric motor. The disc brake carries out a service brake function as a result of the hydraulic actuation of the actuating piston. The actuating piston is actuatable by the electric motor for carrying out a parking brake function.

#Further particulars and features of the invention result from the following description of one exemplary embodiment with reference to the drawings, which show the following:

#FIG. 1 shows one possible embodiment of a disc brake in a top view,

#FIG. 2 shows a portion of the disc brake according to FIG. 1 as a view in the direction of the arrow X in FIG. 1,

#FIGS. 1 through 4 show schematic illustrations of a disc brake 1. The disc brake 1 is a vehicle brake, for example, and may be used in a motor vehicle, for example a passenger vehicle or a truck. FIG. 1 shows the disc brake 1 in a top view, illustrating individual components of the disc brake 1 in a partial sectional view. FIGS. 2 and 4 each show a different view of a portion of the disc brake 1. FIG. 3 shows the disc brake 1 in a sectional illustration. In addition to the disc brake 1, a brake disc 100 schematically indicated by way of example is illustrated in FIG. 3. The brake disc 100 and the disc brake 1 form, for example, a disc brake system 200 or at least integral parts of the disc brake system 200.

#As is apparent in particular from FIG. 1, the disc brake 1 includes a brake carrier 10, a brake caliper 20, multiple brake shoes 30, 30′,31, 31′, and an actuating piston 40. A region of the actuating piston 40 is shown in a partial sectional view in FIG. 1. The brake carrier 10 is stationarily mountable with respect to a vehicle (not illustrated in FIGS. 1 through 4). For this purpose, the brake carrier 10 has at least one, for example two mounting points 11, 11′ for mounting on the vehicle. The mounting points 11, 11′ may be formed by a through hole or a through borehole, or a blind hole, or a blind borehole, in particular a threaded hole (FIG. 2).

#The brake caliper 20 is movably guided on the brake carrier 10 in the direction of the center axis A of the disc brake 1. The brake caliper 20 forms a receiving space 21 for the brake disc 100, the receiving space 21 having two brake sides 22, 23 with regard to the brake disc 100, as is apparent in particular from FIGS. 1 and 3. At least one circular section or circular segment of the brake disc 100 is preferably accommodated by the receiving space 21. For example, for this purpose the brake caliper 20 may overlap the brake disc 100. The brake caliper 20 may have a multi-part, for example a two-part, design. For example, the brake caliper 20 has at least two brake caliper sections 20.1, 20.2 that are mounted opposite one another by means of at least one mounting element 20.3, in particular a screw bolt. The brake carrier 10 may also have a multi-part, for example a two-part, design. For example, the brake carrier 10 has a bridge section 10.1 that is fastened to the brake carrier 10 by means of at least one connecting element 10.2 and overlaps the brake disc 100. A portion of the brake caliper 20 may be connected thereto.
