Abstract

The invention discloses an oil pressure adjusting type friction plate capable of realizing oil film thickness micro adjustment. The oil pressure adjusting type friction plate comprises a friction plate base plate, an elastic body and an oil pressure sensor; the friction plate base plate is of an annular shape, and an annular groove is coaxially formed in the friction plate base plate; the elasticbody covers the position, above the groove, of the friction plate base plate, and the elastic body and the groove form a sealed oil filling cavity; the elastic modulus of the elastic body is smaller than the elastic modulus of the friction plate base plate; the friction plate base plate is provided with an oil inlet communicating with the oil filling cavity, and the oil inlet is connected with anoil cylinder through an oil pipe; and the oil pressure sensor is used for detecting oil pressure borne by the elastic body. According to the friction plate, the thickness of an oil film is adjusted byutilizing the friction plate, so that mechanical transmission is simplified, and micro accurate adjustment of the thickness of the oil film is realized.

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...
