Abstract

The invention provides a testing device of a braker and belongs to the technical field of electron, and the testing device can be used for solving the problems of low testing efficiency and large working strength for testing staff of an existing engine braker. The testing device of the braker comprises a power supply, a central processor connected with the power supply, a detector, a display and a control panel, wherein the detector, the display and the control panel are connected with the central processor; the detector is a photoelectric sensor which is arranged at a piston of the braker and used for detecting the working condition of the piston; and the output end of the central processor is also connected with an electromagnetic valve arranged in an oil transmission path of the braker through a control circuit and can be used for controlling the open and closure of the electromagnetic valve. The testing device of the brake has the advantages of reduced working strength for operating personnel, enhanced testing accuracy and various testing modes.

Description

technical field [0001] The invention belongs to the field of electronic technology, and relates to a test device, in particular to a test device for testing the reliability of a brake. Background technique [0002] With the continuous development of the automobile industry, the performance and total quality of existing automobiles are also continuously increasing, mainly reflected in the increasing power and faster speed of automobiles. Relatively, the increase of vehicle power and vehicle speed leads to the reduction of the vehicle's own deceleration ability. Therefore, the reliability of the braking ability of the vehicle engine brake is particularly important for the safety of the owner when driving. In order to ensure the reliability and safety of the produced engine brake, it needs to be carefully inspected after the engine brake is manufactured. [0003] At present, each manufacturer basically detects the engine brake manually. When testing with this testing method, ...
