Embodiment Construction

[0020] The brake caliper 1 comprises a housing with two caliper arms 2 and 3 which are arranged spaced apart from one another. The brake caliper arms 2 , 3 are connected to one another via a caliper bridge 5 , 5 a or 6 , 7 . They extend approximately half-arched across the brake caliper 1 and form a so-called supporting frame integrated at the edges with the free edges of the brake caliper arms 2 , 3 , which runs around the circumference and is designed to be closed. The supporting frame 8 integrated in the brake caliper 1 forms the longitudinal and transverse edges L1 , L2 and Q1 and Q2 . A reinforcing element V; V1 is connected to this supporting frame 8 , which supports the brake caliper 1 and is connected to the wheel carrier 12 or to such a component of the vehicle.

[0021] The brake caliper 1 is fixedly connected to the wheel carrier 12 or such components on the vehicle via bolts arranged in the fixing seats 10 , 11 , as shown in detail in FIG. 1 . Brake linings 15 , ...

Abstract

In order to avoid oscillations and brake screeching associated with such oscillations, a brake caliper is provided with a reinforcing element. The reinforcing element is formed with a C-shaped profile element that is connected to the brake caliper on the underside of the housing of said brake caliper. The reinforcing element can also be configured in order to hold the brake pads and linings and therefore relieve the housing of the braking torque.

Description

technical field [0001] The invention relates to a brake caliper for a motor vehicle disc brake according to the preamble of claim 1 . Background technique [0002] A brake caliper for a disc brake is known from DE 19911192 A1, which has a closed frame on its underside which follows the contour of the brake caliper. The frame is fixedly connected to the housing of the brake caliper, thereby increasing the rigidity of the brake caliper. [0003] It has been shown that, when the diameter of the brake disc of a disc brake is enlarged, the thickness of the brake caliper bridge must be reduced for the same structural space relationship of the brake caliper in the same vehicle as a brake disc with a smaller diameter. Overall, this measure leads to a reduction in the rigidity of the brake caliper housing and thus to significant vibration problems in the form of natural vibrations and the resulting noise problems, such as brake squeal. Contents of the invention [0004] It is the...
