Abstract

The invention discloses an oil pressure adjustable friction plate capable of micro-adjustment of oil film thickness, which comprises a friction plate base plate, an elastic body and an oil pressure sensor; Covering the friction plate substrate above the groove, the elastic body and the groove form a sealed oil-filled cavity; the elastic modulus of the elastic body is smaller than the elastic modulus of the friction plate substrate; the friction plate substrate is provided with a Through the oil inlet, the oil inlet is connected with the oil cylinder through the oil pipe; the oil pressure sensor is used to detect the oil pressure that the elastic body bears. The invention utilizes the friction plate itself to adjust the thickness of the oil film, thereby simplifying the mechanical transmission and realizing micro-accurate adjustment of the thickness of the oil film.

Description

technical field [0001] The invention relates to the field of power transmission, in particular to an oil-pressure-adjustable friction plate capable of micro-adjustment of oil film thickness, which is used for a fluid-viscosity speed-regulating clutch or a wet clutch. Background technique [0002] On the basis of Newton's law of internal friction, liquid viscous transmission technology relies on the oil film shear force between friction pairs to transmit power. Therefore, the thickness of the oil film, that is, the size of the gap between the friction pairs, has a very important influence on the soft start process and the power that can be transmitted of the entire hydraulic viscous speed control clutch. In traditional fluid viscous clutches, mechanical feeding is often used to adjust the thickness of the oil film between friction pairs, but the complex mechanical transmission structure often leads to a decrease in adjustment accuracy. [0003] In addition, there are current...
