Embodiment Construction

[0014] Before the verification device in the present invention is introduced in detail, first introduce the plate type brake test platform in the prior art, the plate type brake test platform includes a base body 5 and a pair of front wheels 2 for manufacturing a car A front brake bench 11 for dynamic inspection and a pair of rear brake benches 12 for performing brake inspection on the rear wheels of the automobile, two brake benches in the pair of front brake benches are arranged at intervals from left to right The two brake plates in the pair of rear brake plates are arranged at intervals from left to right. The base body can be a metal structure or a concrete structure. A force sensor 13 arranged horizontally is arranged between the base body and the corresponding braking platen. The force sensor is used to detect the braking force borne by the braking platen. A vertically arranged load cell 6 is arranged between the brake plates, and the load cell is used to detect the axl...

Abstract

The invention relates to a verification device for a brake inspection platform. The verification device includes a force sensor verification portion. The force sensor verification portion includes a base body fixing seat and a table plate fixing seat for being connected with the upper end of a corresponding brake table plate during use, the left side and the right side of the base body fixing seatare provided with bolt punched holes for being connected with corresponding portal frame connecting threaded holes through bolts, a force sensor verification mechanism is arranged between the base body fixing seat and the table plate fixing seat and includes a force application mechanism and a standard force sensor, the force application mechanism is a hydraulic cylinder, a pneumatic cylinder oran electric push rod, the base body fixing seat includes a force application mechanism mounting base for mounting the force application mechanism, a left adjusting seat and a right adjusting seat aremovably assembled on the left side and the right side of the force application mechanism mounting base in the left-right direction, and the bolt punched holes are formed in the left adjusting seat andthe right adjusting seat. According to the verification device, the problem that in the prior art, during force sensor verification, a horizontal verification force needs to be provided by means of an automobile at a certain speed, so that the verification is inconvenient is solved.

Description

technical field [0001] The invention relates to a verification device for a brake inspection platform in the field of verification. Background technique [0002] The braking performance of the vehicle is an important indicator 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, the braking performance of vehicles is basically tested and evaluated by using the desktop method to detect and evaluate the braking performance of vehicles. 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 effect of inertial force, the pressure of the front wheel on the brake plate increases, and the pressure of the rear wheel brake plate decreases, that is, the...
