Abstract

The invention provides a mechanism for measuring friction force / friction coefficient and a measuring method thereof, and solves the problem that the friction force / friction coefficient of two friction pairs with unconventional structures can be measured when the performance of a clutch detection product is adjusted to meet the requirement or not. The mechanism comprises a pressing force unit, a rotating unit, a thrust unit, a measured piece fixing tool and a force sensor, wherein the pressing force unit is used for pressing and fixing the measured piece fixing tool, and the thrust unit is connected with the rotating unit through a thrust rod and used for applying thrust to the rotating unit; the to-be-measured mating plate or the tool is clamped below the rotating unit; the measured piece is installed on the measured piece fixing tool; and a force sensor is arranged between the rotating unit and the thrust unit and used for measuring the maximum acting force of the thrust unit pushing the rotating unit to rotate.

Description

technical field [0001] The invention relates to a device for measuring friction force / coefficient of friction, in particular to a mechanism for measuring friction force / coefficient of friction and a measuring method thereof. Background technique [0002] For automobile transmission, the clutch is a key transmission assembly connecting the engine and the transmission. The self-adjusting clutch is one of them. The realization of its self-adjusting function involves the friction of two friction pairs, but the two friction pairs None of the structures are common shapes, one is a rotating slope distributed in the circumferential direction, and the other is a butterfly-shaped part surface. In order to check whether the performance of the product meets the requirements, it is necessary to measure the friction (coefficient of friction) at the two friction pairs. However, there is no mature tooling, mechanism or equipment in the prior art equipment to meet the requirements for measur...
