Dual steel disc with axial through groove structure for wet clutch

Abstract

The invention discloses a dual steel disc with a axial through groove structure for a wet clutch. The dual steel disc comprises a dual steel disc body and axial through grooves, and the integrally formed axial through grooves are uniformly distributed in the vicinity of an inner ring of the wet clutch dual steel disc body; the orthographic projection of the single axial through groove on a plane perpendicular to the axis of the wet clutch dual steel disc body can be I-shaped, L-shaped, T-shaped, Y-shaped and the like; the degree of the dual steel disc body being intruded by the axial through grooves at different circumferential positions is not necessarily the same, but the orthographic projection of all axial through grooves in the plane perpendicular to the axis of the wet clutch dual steel disc body is a rotational symmetric graph. According to the dual steel disc, the heat dissipation area and the convection heat exchange coefficient of the steel disc can be remarkably increased, rapid and thorough separation of the dual steel disc is facilitated, lightweight design and low-cost manufacturing of the steel disc are facilitated, and the problems of overheating failure in the vicinity of the inner ring, warping deformation of the inner ring and the like frequently occurring in an existing common dual steel disc are greatly improved.

Description

technical field [0001] The invention belongs to the technical field of vehicle transmission, and in particular relates to a paired steel plate with an axial through groove structure used for a wet clutch. Background technique [0002] The wet clutch uses the hydraulic pressure of the clutch engagement. In the process of clutch separation and full engagement, it also includes a transmission device that controls the driving force under the condition of relative rotation. The dual steel plates and friction plates in the wet clutch are arranged alternately to form friction Plate group, the driving end of the wet clutch is connected with the counter steel plate through splines, and the driven end of the wet clutch is connected with the friction plate through splines. When the wet clutch is engaged, the friction plate set is compressed, and the engine output torque is transmitted to the driven end of the wet clutch through the friction pair between the dual steel plate and the fri...

Problems solved by technology

[0006] In view of the above-mentioned defects, the object of the present invention is to provide a paired steel plate with an axial through-slot structure for wet clutches, which has a simple structure and is easy to produce, and strengthens the weight of the paired steel plate while reducing the weight of the paired steel plate. Excellent convective heat transfer capacity reduces the maximum temperature of the paired steel sheet, largely solves the problems of warping and deformation of the inner ring of the conventional steel sheet, and facilitates the rapid and complete separation from the friction sheet
