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.

Embodiment Construction

[0027] Because the traditional clutch includes pressure plate assembly, driven plate, diaphragm spring, release bearing, rocker arm and resistance mechanism, etc., it involves many parts, heavy weight, many failure points, and is inconvenient to maintain.

[0028] In order to solve the problem of insufficient engagement force of the existing clutch or mutual friction between the fixed armature and the movable armature, the present invention enables the gap between the two armatures to be within the preset range after the clutch is separated through accurate positioning between the movable armature and the end cover. Ensure that the clutch has sufficient suction force to achieve fast suction.

[0029] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0030] Such as figure 1 As shown, a toothed electroma...

Abstract

The invention relates to the technical field of clutches, in particular to a toothed electromagnetic clutch. It includes a movable gear sleeve and a fixed gear sleeve that are meshed with each other. The outer side of the fixed gear sleeve is equipped with a fixed armature. There is a gap between the fixed armature and the fixed gear sleeve, and the position is fixed. A movable armature is rotatably set on the outer side of the motor, and the movable armature can move axially with the movable gear sleeve. After the electromagnetic coil is energized, the movable armature is attracted to the fixed armature, so that the movable gear sleeve and the fixed gear sleeve are meshed. The invention provides an electromagnetic clutch system with compact structure, no auxiliary execution structure and convenient operation, which is applied to the electric drive system of new energy vehicles, and the system controls the transmission and disconnection of power torque.

Description

technical field [0001] The invention relates to the technical field of clutches, in particular to a toothed electromagnetic clutch. Background technique [0002] The electric drive system of new energy vehicles must use a power on-off mechanism in order to realize switching between different working modes. Because the traditional clutch includes pressure plate assembly, driven plate, diaphragm spring, release bearing, rocker arm and resistance mechanism, etc., it involves many parts, heavy weight, many failure points, and is inconvenient to maintain. [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 as one, after the electromagnetic coil is energized, the movable gear sleeve meshes with the fixed gear sleeve, 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 co...
