Abstract

The invention discloses a brake input pressure measurement sensor for a disc brake. The sensor comprises a bearing plate and a support plate, wherein the bearing plate and the support plate are connected with each other and form an I-shaped structure; two grooves are respectively formed at the front side and the rear side of the support plate; the front groove and the rear groove are respectively provided with two blind holes, a strain gauge is posted on the bottom surface of each blind hole, the front groove and the rear groove are mutually symmetrical, and the four blind holes are symmetrical at front and back as well as at left and right; the strain gauges arranged at the same side are symmetrically posted, and the strain gauges at the front and back symmetrical positions are posted along the reverse directions; a tension strain part and a compression strain part of each strain gauge are sequentially arranged along the vertical direction; the four strain gauges are connected with one another by cables and form a full-bridge strain circuit; a socket is arranged at the middle position of the groove formed at the front side of the support plate; an input end and an output end of the full-bridge strain circuit are connected with the socket respectively by a cable. The sensor is accurate in measurement, and can simulate the structural size of a real automobile brake disc by means of the overall structure, thus providing an effective testing means for studying the performance of an automobile disc brake and a brake pad.

Description

technical field [0001] The invention relates to a brake input pressure measuring sensor of a disc brake, which is used for testing the performance of the brake. Background technique [0002] In the development of disc brakes, in order to simulate the real use state and test the relationship between brake control and actual output, it is necessary to measure the actual pressure value of the brake exerted on the brake disc through the brake pads. [0003] Due to the limited size of the actual brake and the large braking force (up to 200kN), in actual development, it is usually designed through theoretical simulation without actual testing, so that the control accuracy of the brake, the performance of the brake and the brake pad cannot be obtained. Guarantee, and then can not guarantee the absolute safety of automobile braking. Contents of the invention [0004] The object of the present invention is to provide a brake input pressure measuring sensor for a disc brake in orde...
