High-precision flat plate-type brake test bench

Abstract

The invention provides a high-precision flat plate-type brake test bench, which is composed of a supporting frame, a brake soleplate, a bearing frame, brake force detection mechanisms, a wheel weight detection mechanism and a guide limiting mechanism, wherein two sides of the supporting frame are symmetrically provided with two grooves, the notch of each groove faces inwardly, and thus, the supporting frame presents a symmetrical structure in a shape like a Chinese character zhong; the bearing frame is arranged at the inner side of the supporting frame; the brake soleplate is fixedly arranged above the bearing frame; two groups of brake force detection mechanisms are symmetrically arranged in the grooves at two sides of the supporting frame; the wheel weight detection mechanism is located between the bearing frame and the bottom plate of the supporting frame; and the guide limiting mechanism is connected with the bearing frame and the supporting frame. The technical scheme of the invention can effectively improve defects existing in aspects such as the overall frame structure of the traditional flat plate-type brake test bench and the wheel brake equivalent transfer and brake force acquisition, and the brake force detection precision of the flat plate-type brake test bench is improved.

Description

technical field [0001] The invention belongs to the technical field of vehicle performance detection, is suitable for vehicle braking performance detection, and in particular relates to a high-precision flat-plate brake inspection platform. Background technique [0002] The braking performance of the vehicle is an important index in the safety performance of the vehicle, which is directly related to the driving safety, and is actually related to the safety of life and property. Therefore, the braking performance detection occupies an important position in the field of vehicle performance detection. At present, vehicle performance testing institutions basically use the desktop method to test and evaluate vehicle braking performance. The desktop method testing equipment mainly includes: reaction force roller brake test bench, flat plate brake test bench. When the car is braking, due to the inertial force, the pressure of the front wheel on the brake plate increases, and the p...
