Embodiment Construction

[0047] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0048] exist figure 1 A diagram illustrating the overall configuration and operation of an electromagnetic clutch having an actuator according to the present embodiment is shown in .

[0049] An input side gear 32 having claws on the outer periphery is provided on the input shaft 30 . In addition, a hollow output shaft 34 is disposed so as to surround the input shaft 30 , and an output side gear 36 having claws on the outer periphery is provided on the output shaft 34 . Also, these input side gears 32 and output side gears 36 have the same diameter and are arranged at a predetermined distance in the axial direction.

[0050] On the outer sides of the input side gear 32 and the output side gear 36 , a hollow cylindrical sleeve 10 movable in the axial direction is disposed. The sleeve 10 can mesh with only the input side gear 32 or with both the input side gear 32 and ...

Abstract

Provided is a dog clutch actuator comprising a sleeve (10) having dog teeth made engageable with the dog teeth formed in a power transmission shaft (30) and made movable in the axial direction, and aplunger (14) for moving together with the sleeve (10). The plunger (14) is axially moved through a yoke (16) by electric currents to flow through coils (18 and 20). The dog clutch actuator is so characterized by the shapes of the plunger (14) and the yoke (16) that a sucking force increases in the engaging direction, when the dog clutch is engaged, and decreases in the disengaging direction, whenthe dog clutch is disengaged.

Description

technical field [0001] The present invention relates to a claw clutch actuator for driving a claw clutch (dog clutch, jaw clutch) that engages claws (dog teeth) to transmit power. Background technique [0002] In a driving force transmission system of a vehicle or the like, a clutch is an important component and is widely used. Known various forms for this clutch, just need some kind of drive mechanism in order to control its engagement, disengagement (release). As such a drive mechanism, a mechanism using hydraulic pressure has been widely known, but there is a problem that it is relatively large and has low efficiency and is not suitable for high-speed operation. [0003] Patent Document 1 discloses an electromagnetic clutch that controls a clutch by energizing a coil. In this electromagnetic clutch, when the coil is not energized, the clutch is returned to one side using a spring. In addition, Patent Document 2 discloses an electromagnetic clutch that maintains the sta...
