Abstract

The invention discloses a measuring device used for measuring friction coefficients of disk-type friction sheets, and a measuring method thereof. The measuring device comprises a measuring tooling and a control system; a torque sensor and an angular velocity sensor are adopted by the measuring tooling, and are connected via a telescopic force arm lever, a guide rod, cone gear wheels, and a standard block; the standard block is dragged by a dragging motor to rotate on a test piece; the dragging motor is driven by the control system to rotate, and signals of the angular velocity sensor and the torque sensor are collected; in measuring, the value of torque is adjusted continuously by the dragging motor based on feedback of the angular velocity sensor until angular velocity is stable, and the friction coefficients of a friction sheet is calculated based on the value of torque and the mass of the standard block. The measuring device is suitable for friction coefficient measuring of friction plates which are applied to engineering vans of different types and possesses different semi-diameters.

Description

technical field [0001] The invention belongs to the technical field of a disc friction plate friction coefficient measuring device and its measurement technology, and in particular relates to a disc friction plate friction coefficient measuring device and a measuring method thereof. Background technique [0002] High-energy-density friction transmission system is the key to high-performance transmission. Its notable feature is high power and high speed. Cu-based and Fe-based powder metallurgy friction pairs are widely used in engineering due to their excellent wear resistance and high heat capacity. field of vehicle transmission. Due to its high-speed and heavy-load working environment, the friction plate will produce non-uniformly distributed wear along the radial direction, resulting in a decrease in the friction coefficient and reduced braking capacity. During the vehicle inspection, if it cannot be detected accurately, the error will be too large, and the consequences c...
