Problems solved by technology

At present, in order to realize the speed regulation of 0-100%, the dual plates are generally concentric discs with smooth upper and lower surfaces, which will increase the difficulty of control and cause vibration of the dual plates and friction plates when the clutch is working. Decreased clutch efficiency

Abstract

The invention provides a hydroviscous variable speed clutch dual disc capable of increasing bearing capacity and preventing vibration. The clutch dual disc is of an annular structure, and multiple pits are formed in the inner and outer surfaces of the clutch dual disc. The multiple pits are each in a cylinder or a circular truncated cone or a cone or a frustum or a hemispherical shape. The pits are distributed along the radial circumference of the center of the clutch dual disc. The clutch dual disc is made of medium carbon steel or carbon spring steel. The depth h of the pits is less than orequal to 0.1 mm. The surface texture ratio k of the clutch dual disc is less than or equal to 0.4. By the adoption of the hydroviscous variable speed clutch dual disc, the film forming ability and dynamic pressure bearing capacity of viscous liquid between friction pairs can be realized, the vibration during oil film speed regulation is weakened, the working performance of a hydroviscous variablespeed clutch is improved, and the energy saving effect is realized.

Description

technical field [0001] The invention relates to the field of friction components or clutches, in particular to a pair plate of a fluid-viscous speed-regulating clutch with increased bearing capacity and anti-vibration. Background technique [0002] Liquid viscous transmission is a new type of fluid transmission that utilizes the shearing action of the oil film to transmit power. The dual plate is a key part of the liquid viscous clutch, which can transmit torque to the output shaft. Currently, the dual plate is mostly made of steel with smooth inner and outer surfaces. piece. When the hydraulic viscous speed regulating clutch is working, in order to achieve the purpose of changing the output shaft speed, the distance between the dual plate and the friction plate will be adjusted through the movable piston on the input shaft. During the start-up phase of the clutch, when the oil between the dual plate and the friction plate is subjected to axial extrusion, due to the small b...
