Abstract

The invention relates to a support frame (10) for a brake test platform (11), the support frame comprising a test piece frame (1) and a driver frame (7), wherein the test piece frame (1) is configured to support a brake test unit (12), and wherein the drive frame (7) is configured to support the brake drive unit (13). The support frame (10) according to the invention is characterized in that the support frame (10) also comprises a coupling device (2) configured to automatically bring the test piece frame (1) and the driver frame (7) to each other In the state of oscillatory coupling and brought to the state of mutual oscillatory decoupling. Furthermore, the invention relates to a corresponding test piece frame (1), a corresponding drive frame (7) and a brake test platform (11).

Description

technical field [0001] The invention relates to a support frame for a brake test platform, a test piece frame for an at least two-modular support frame, a drive frame for an at least two-modular support frame and a corresponding brake test platform. Background technique [0002] Different types of test benches for testing the braking effect of motor vehicle brakes are known from the prior art. These kinds of test platforms usually comprise a measuring device for detecting the braking torque generated by the brake to be tested and a drive device for generating the driving torque. The more rigid the test platform, the higher the braking or driving torque available for testing the brake. On the other hand, the high rigidity of the test platform results in the undesired transmission of oscillations of the drive device to the measuring device, which adversely affects the measurement accuracy of the measuring device. [0003] In this regard, DE 10 2014 002 260 A1 describes a bra...
