Abstract

The hydro-viscous transmission device for predicting and controlling the buckling deformation of the friction plate comprises a power bracket, a power input component, a power output component and a friction plate buckling deformation control mechanism, the power input component comprises an input shaft, a [-shaped driving piece support, a driving oil disc in the driving piece support, a driving piece arranged at the end of the driving oil disc and a power input auxiliary device. The power output component comprises an output shaft, a driven disc, a driven piece support, a driven piece and a power output auxiliary device. According to the friction plate buckling deformation control mechanism, a plurality of arc steel sheets are evenly distributed on the peripheral sides of a driving plate and a driven plate, driving devices are connected between the arc steel sheets and a driving plate support and between the arc steel sheets and a driven plate support, and resistive arc strain gauges are further arranged between the arc steel sheets and the driving plate or between the arc steel sheets and the driven plate. According to the invention, the radial constraint of the friction plate of the hydro-viscous differential transmission device is realized through the hydraulic loop and the resistive arc strain gauge, and the purpose of controlling buckling deformation is achieved.

Description

technical field [0001] The invention belongs to the technical field of fluid-viscous transmission, and in particular relates to a fluid-viscous transmission device for predicting and controlling the warping deformation of a friction plate. Background technique [0002] Liquid viscous transmission is a new type of fluid transmission that uses the viscosity or shear force of liquid to transmit power. Its working principle is based on Newton's law of internal friction, which can realize stepless speed regulation, and has the remarkable advantages of stable start and high controllability. . Due to the uneven distribution of thermal stress in the friction pair system, the friction plate is prone to warping deformation along the radial direction, which has a significant impact on the fluid-viscous flexible transmission process. [0003] At present, most of the existing technologies are to cool the friction plate by opening cooling oil grooves on the surface of the friction plate,...
