Multi-part brake caliper having at least one hollow section
The invention concerns a multi-part brake caliper for a vehicle disc brake, the brake caliper comprising: a first part comprising a portion that is arrangeable at a first side face of a brake disc of the vehicle disc brake and that is configured to receive a brake piston; a second part that is formed separately from the first part and comprises a finger portion that is arrangeable at a second side face of the brake disc; wherein the first part is a metal casted part and the second part comprises sheet metal and wherein the second part further comprises at least one at least partially enclosed hollow section.
1 . A multi-part brake caliper for a vehicle disc brake, the brake caliper comprising:
a first part comprising a portion that is arrangeable at a first side face of a brake disc of the vehicle disc brake and that is configured to receive a brake piston;
a second part that is formed separately from the first part and comprises a finger portion that is arrangeable at a second side face of the brake disc;
wherein the first part is a metal casted part and the second part comprises sheet metal sections and wherein the second part further comprises at least one at least partially enclosed hollow section,
wherein the brake caliper has a middle portion that is arrangeable opposite to a circumferential surface of the brake disc, the middle portion being comprised either by the first part or by the second part,
wherein the middle portion extends from a finger side to a piston side,
wherein the middle portion comprises a sheet metal section with a reduced thickness that forms at least part of an upper side of the middle portion, and
wherein an average or maximum thickness of the sheet metal sections comprised by the finger portion exceeds an average or maximum thickness of the sheet metal sections comprised by the middle portion.
2 . The brake caliper according to claim 1 ,
wherein the second part comprises the middle portion and wherein the hollow section is provided in the middle portion.
3 . The brake caliper according to claim 2 ,
wherein the hollow section is comprised at least partially by the finger portion, and
wherein each of the finger portion and the middle portion comprises a hollow section.
4 . The brake caliper according to claim 3 ,
wherein the hollow sections in the finger portion and in the middle portion are connected to one another.
5 . The brake caliper of claim 1 ,
wherein the first part and the second part are secured to one another by welding.
6 . The brake caliper of claim 1 ,
wherein the first part and the second part are mechanically secured to one another by means of at least one mechanical fixing element in particular wherein the mechanical fixing element is connected to an upper side of the first part that faces away from a circumferential face of the brake disc.
7 . The brake caliper according to claim 1 ,
wherein the first part and the second part are non-disassemblable parts.
8 . The brake caliper according to claim 1 ,
wherein the hollow section is filled with a vibration damping material.
9 . The brake caliper according to claim 1 ,
wherein the hollow section is comprised at least partially by the finger portion.
10 . The brake caliper according to claim 1 ,
wherein the middle portion has a plurality of hollow sections,
wherein the plurality of hollow sections extend in parallel to one another and in parallel to a rotation axis R of the brake disc.
11 . A method of producing a brake caliper for a vehicle disc brake, the brake caliper comprising:
a first part comprising a portion that is arrangeable at a first side face of a brake disc of the vehicle disc brake and that is configured to receive a brake piston;
a second part that is formed separately from the first part and comprises a finger portion that is arrangeable at a second side face of the brake disc;
wherein the first part is a metal casted part and the second part comprises sheet metal sections and wherein the second part further comprises at least one at least partially enclosed hollow section;
wherein the brake caliper has a middle portion that is arrangeable opposite to a circumferential surface of the brake disc, the middle portion being comprised either by the first part or by the second part,
wherein the middle portion extends from a finger side to a piston side,
wherein the middle portion comprises a sheet metal section with a reduced thickness that forms at least part of an upper side of the middle portion, and
wherein an average or maximum thickness of the sheet metal sections comprised by the finger portion exceeds an average or maximum thickness of the sheet metal sections comprised by the middle portion,
the method comprising:
securing the first part and second part to one another.
