Anti-deformation dual disc of hydro-viscous speed regulating clutch

Abstract

The invention provides an anti-deformation dual disc of a hydro-viscous speed regulating clutch. The dual disc is a ring-shaped steel disc with the thickness being 2 to 5mm; and spline teeth are arranged on the inner ring or the outer ring of the ring-shaped steel disc. The anti-deformation dual disc is characterized in that the working surface of the dual disc is wavy, is uniformly provided with concentric ring-shaped grooves along the radial direction and is uniformly provided with radial rectangular grooves along the circumferential direction. The anti-deformation dual disc provided by the invention has the advantages that the radiating condition of friction pairs is improved, the film-forming capability and the kinetic-pressure bearing capability of viscous liquid medium among the friction pairs are enhanced, the thermal deformation of the dual disc of the hydro-viscous speed regulating clutch is reduced, the generation of non-thorough separation between a driving friction part and a driven friction part is prevented, the working performance of the hydro-viscous speed regulating clutch is improved and the service life of the hydro-viscous speed regulating clutch is prolonged.

Description

technical field [0001] The invention belongs to the field of friction components, in particular to a anti-deformation fluid viscous speed regulating clutch pair plate. Background technique [0002] The dual plate is a key part of the fluid viscous clutch. During the working process, there is a long-term relative sliding between the dual plate and the friction plate, which generates a lot of frictional heat. Since the dual plate is mostly in the form of a smooth surface, the heat dissipation conditions of the friction pair are not good. Well, a large amount of frictional heat can easily lead to thermal deformation of the dual plate, and the deformation of the dual plate will seriously affect the performance and service life of the fluid-viscous clutch, and even cause major safety accidents; moreover, the traditional dual plate is made of flat The planar thin disc structure easily leads to incomplete separation of the dual plate and the friction plate when the clutch is diseng...
