Load transmission guide groove structure on main turntable of electromagnetic torsion bar clutch, and design method

Abstract

The invention relates to a load transmission guide groove structure on a main turntable of an electromagnetic torsion bar clutch, and a design method. Each guide groove is provided with upper and lower vertex angle openings; the guide grooves are connected with torsion bar grooves through transition arcs; each guide groove is provided with a cylindrical guide groove or a prismatic guide groove; the cross section, passing through the center of each bearing steel ball, of a contact point of the bearing steel ball and the corresponding guide groove is a bearing cross section; the bearing sectionof each cylindrical guide groove is a circular bearing section; the bearing section of each prismatic guide groove is a rhombic bearing section or a square bearing section; and a gap is reserved between each guide groove and each bearing steel ball. A design method comprises the following steps of (1), the structural form design of the load transmission guide grooves of the main turntable, (2), the size design of the bearing sections of the load transmission guide grooves, (3), the width design of the upper and lower vertex angle openings of the guide grooves, and (4), the transition arc design of the load transmission guide grooves. The guide groove structure can simultaneously meet the functions of torque transmission and guidance.

Description

technical field [0001] The invention relates to a main turntable of an electromagnetic torsion bar clutch, in particular to a guide groove structure of the main turntable of an electromagnetic torsion bar clutch. Background technique [0002] Gearboxes in automobile power transmission systems usually require dual clutches to realize the flexible conversion function of the transmission ratio. The electromagnetically driven dual clutches involved in the present invention are simple in structure, high in efficiency, and low in impact and vibration, which can meet the requirements of the whole new energy vehicle. vehicle performance requirements. The magnitude of torque transmitted by the clutch is completely determined by the strength and stiffness characteristics of the elastic torsion bar, which not only can transmit high torque, but also can ensure the stability and uniformity of torque transmission. During the engagement-disengagement process of the electromagnetic torsion...

AI Technical Summary

Problems solved by technology

If the gap between the guide groove and the load-bearing steel ball is too small, it will easily cause the ball to be stuck, and if the gap is too large, it will easily cause collision. During the clutch engagement-disengagement process, it will affect the load transmission and the guidance of the steel ball
