Tooth embedding type electromagnetic clutch

Abstract

The invention relates to the technical field of clutches, and particularly relates to a tooth embedding type electromagnetic clutch. The tooth embedding type electromagnetic clutch comprises a movingtooth sleeve and a fixed tooth sleeve which are engaged with each other to realize transmission, wherein a fixed armature sleeves the outer side of the fixed tooth sleeve; a gap with fixed position isformed between the fixed armature and the fixed tooth sleeve; a movable armature rotatably sleeves the outer side of the movable tooth sleeve and can axially move along with the movable tooth sleeve;after an electromagnetic coil is charged, the movable armature is sucked to the fixed armature, so that the movable tooth sleeve and the fixed tooth sleeve are engaged with each other. The inventionprovides an electromagnetic clutch system which is compact in structure, does not need an assistant performing structure, and is convenient to operate; the electromagnetic clutch system is applicableto an electric driving system of a new energy vehicle; and system is capable of controlling the transmission and cutting off of power torque.

Description

Technical field [0001] The present invention relates to the technical field of clutches, in particular to a tooth embedded electromagnetic clutch. Background technique [0002] The electric drive system of a new energy vehicle must use a power on-off mechanism in order to switch between different working modes. Traditional clutches include pressure plate assembly, driven plate, diaphragm spring, release bearing, rocker arm and resistance mechanism, etc., which involve many parts, heavy weight, many failure points, and inconvenient maintenance. [0003] The existing electromagnetic clutch system applied to the new energy electric drive system, because the movable gear sleeve and the movable armature are solidified into one body, after the electromagnetic coil is energized, the movable gear sleeve and the fixed gear sleeve mesh, and the two rotate synchronously and transmit torque At this time, it is required that the fixed armature and the movable armature cannot be in contact, oth...

AI Technical Summary

Problems solved by technology

[0005] In view of the above problems, the purpose of the present invention is to provide a toothed electromagnetic clutch to solve the problem that when the movable toothed sleeve and the fixed toothed sleeve of the existing clutch are separated, the suction force is insufficient due to the excessive gap, or the movable toothed sleeve and the fixed toothed sleeve are separated. After the tooth sleeve is attracted, the gap is too small, which causes the problem that the fixed armature and the movable armature cannot be separated due to residual magnetism and are damaged due to mutual friction.
