Wet clutch friction plate with bionic oil groove structure

Abstract

The invention discloses a wet clutch friction plate with a bionic oil groove structure, and belongs to the technical field of automobile clutch friction plates. The wet clutch friction plate consists of a core plate and friction liners, wherein the two friction liners are symmetrically and fixedly connected with the front side and the back side of the core plate; radial oil grooves and annular oil grooves are formed in surfaces of both two friction liners; bionic micro structures consisting of guide grooves and bionic unit grooves are arranged at the bottoms of the oil grooves. Therefore, by adopting the wet clutch friction plate, an excellent one-way conveying guide function on cooled lubricating oil can be achieved, the flowing speed of the lubricating oil in the oil grooves can be effectively increased, heat convection between the lubricating oil and the friction plate can be improved, and surface temperature increase of the friction plate can be remarkably reduced; due to the combination of the radial oil grooves and the annular oil grooves, a unique composite oil groove mode can be achieved, failure situations such as over heat and deformation caused by concentrated heat stress on the surface of the friction plate can be alleviated, the performance of the friction plate can be comprehensively improved, and the service life of the friction plate can be prolonged.

Description

technical field [0001] The invention belongs to the technical field of vehicle clutch friction plates, and is especially used for heavy-duty vehicle transmission gear shifting operations, in particular to a wet clutch friction plate with a bionic oil groove structure. Background technique [0002] 1. Wet clutch refers to the friction of the friction plate in the process of sliding and grinding, and the friction contact surface shows the friction of the liquid and semi-liquid interface. The wet friction clutch is one of the core components to ensure the normal operation of the heavy-duty vehicle transmission. It relies on the friction torque of the shift clutch friction plate or the rigid combination of the force transmission elements to transfer energy to achieve the purpose of outputting different torques and speeds. The material, structure and parameters of the friction plate are important factors affecting the performance of the wet clutch, and are also important factors ...

[0004] 3. At present, the common forms of oil grooves on the surface of wet clutch friction plates are: radial grooves, waffle grooves, three-way multi-channel parallel grooves, two-way multi-channel parallel grooves, double arc grooves, spiral grooves and other forms. The friction performance and heat dissipation effect of the oil groove form are different

At present, the optimization of the oil tank focuses on the form of the oil tank, the cross-sectional shape of the oil tank, and the angle of inclination, etc., and there is little research on the optimization of the internal microstructure of the oil tank.
