Abstract
The invention relates to a driving friction plate for a wet clutch. The driving friction plate comprises a friction steel disc and a friction liner; the friction steel disc is a circular steel sheet, and raised teeth are uniformly distributed on an outer circumference; and the friction liner is formed by adhering a circular sheet to the friction steel disc and is made of a paper based friction material, an end face is arched, and eight triangular radial grooves which are distributed on the end face in the circumferential direction. By adopting the driving friction plate, the flowing dead space in the grooves can be avoided, the meshing time of the wet clutch can be reduced, the contact pressure in the meshing process of the wet clutch can be increased and output torque is large.
Description
Technical field
The present invention relates to a kind of active friction plate of wet clutch.
Background technique
Wet clutch is mainly used on the heavy machineries such as vehicle, large fan, and it is carried out stepless speed regulation.Its basic principle is a law of friction in the newton: be full of lubricant oil between two parallel flat boards, form certain thickness oil film.Power is passed to from movable friction plate by active friction plate, and the relative velocity between two friction plates diminishes gradually, until being zero.Shearing stress that oil film transmitted size is directly proportional with the viscosity of liquid, is inversely proportional to the relative velocity of flat board, is inversely proportional to oil slick thickness.In the working procedure of wet clutch, the factor that influences the transmission of wet clutch moment of torsion has a variety of, wherein is mainly for the quantity of groove and the characteristic of shape and friction facing the most.The friction pair of traditional wet clutch comprises active friction plate and from movable friction plate, has four grooves on its active friction plate that mostly groove is rectangle; The friction material end face is the plane, and during engagement, the distortion of position, middle footpath is bigger.This friction plate transmitting torque is less, and in the joggleword process, radiating effect is relatively poor, is unfavorable for the wet clutch proper functioning.
Summary of the invention
The objective of the invention is to defective to existing technology; A kind of active friction plate of wet clutch is provided; Can avoid the inner dead space that flows that forms of groove, reduce wet clutch engagement time, it is big to have handled in the rubbing surface path position compressive deformation effectively; Improve contact pressure in the engagement process, output torque is big.
For achieving the above object, the present invention adopts following technical proposals:
A kind of active friction plate of wet clutch comprises friction steel disk and friction facing, it is characterized in that:
1), said friction steel disk is the ring steel disc, excircle has even distribution double wedge;
2), said friction facing is on the rubbing surface of ring sheet attached to said friction steel disk, the friction facing material is a paper friction material;
3), said friction facing exterior edge face is arcuate surface, promptly radially the upper surface profile of section is arch, and has 8 triangle radial grooves that circumferentially are uniformly distributed with.
Above-mentioned friction steel disk is the ring steel disc, and thickness is 6mm.
Above-mentioned friction facing, thickness are 0.1 ~ 0.12mm.
The height of projection that above-mentioned friction facing exterior edge face is arcuate surface is 0.01 ~ 0.015mm, 5 ° ~ 8 ° of above-mentioned groove widths, and groove depth is 0.03mm.
The present invention has following conspicuous outstanding substantive distinguishing features and remarkable advantage compared with prior art: this device has simply, reliable, and lack engagement time, and contact pressure is big, and good heat dissipation effect can provide than high pulling torque.
