Online performance detection method for mineral explosionproof rubber-tired vehicle

Abstract

The invention provides an online performance detection method for a mineral explosionproof rubber-tired vehicle. The online detection method comprises the following steps: vehicle information registration; vehicle speedometer error detection; vehicle power performance detection; vehicle exhaust emission detection; vehicle brake performance detection; vehicle appearance and chassis four-wheel positioning detection; vehicle headlamp light intensity detection; vehicle sideslip detection; and printing of a detection report for a detected vehicle by a computer operator on a printing interface of amanagement program on a management computer. The detection method provided by the invention has the advantages that power-on self-inspection and failure screening functions are achieved; and the reliability and practicality are high.

Description

technical field [0001] The invention relates to a vehicle performance detection method, in particular to a performance detection method of an explosion-proof rubber-tyred vehicle used in coal mines, belonging to the vehicle detection category.

[0002] The publication number is CN 202049006U, which discloses a utility model patent of "a method for measuring dynamism of automobile chassis", including two hydraulic brakes, two drums, two dynamometer motors and two hydraulic brakes in a symmetrical direct connection arrangement. The two drums are rigidly connected by shafts, and the two dynamometer motors are symmetrically arranged on both sides of the two drums and are respectively connected to the two drums through couplings. The torque and speed information of the dynamometer motors and hydraulic brakes are fed back to the center. control system, and then the central control system outputs a new control signal to the hydraulic brake and the dynamometer motor to measure the resistance of the dynamometer system. The power efficiency of mining explosion-proof rubber-tyred vehicles cannot be analyzed, and the pros and cons of a rubber-tyred vehicle cannot be evaluated in an all-round way.

[0003] The publication number is CN203051647U, which discloses a utility model patent of "a belt transmission device for chassis dynamometer", including a driving wheel, a driven wheel, a wedge belt, and a tensioning device. The shaft rotates, and the vehicle drive wheel is arranged above the wedge belt, and the tension device is arranged below the wedge belt, which is used for the belt transmission device of the chassis dynamometer, so that during the vehicle dynamometer test, the vehicle drive wheel rolls on the transmission belt The friction generated between the contact between the belt and the wheel and the friction generated between the contact between the belt and the pulley transmit the movement and force of the drive wheel. When this belt transmission device is used for chassis dynamometer, the wheel is pressed against the wedge belt due to the weight of the vehicle. After being on, the wedge-shaped belt will be dented and deformed, which is very different from the real road conditions when the wheel is pressed
