Problems solved by technology

[0004] In the conventional dog clutches, since the front end surfaces of the claws of the first and second dog clutch members are flat, the second dog clutch member is moved towards the first dog clutch in order to be in the clutch connection state. When moving sideways, the front faces of the clutch claws collide with each other, and the movement operation has to be repeated

Abstract

The present invention provides a dog clutch capable of obtaining a clutch on condition smoothly while reducing torque shock by clutch on operation at a time always. This dog clutch is composed of a first dog clutch member 32 connected with a rotary transmission member 11b supported rotatably on a transmission shaft 3 with relative rotation play [theta], a second dog clutch member 15b supported slidably on the transmission shaft 3 to engage and disengage with / from it, and a damper spring provided between the rotary transmission member 11b and the first dog clutch member 32. A first dog tooth 41 and a second dog tooth 42 like a gear engaging and disengaging mutually by travel in the axial direction of the second dog clutch member 15b are formed in the first dog clutch member 32 and the second dog clutch member 15b. Chamfers 41a, 42a for guiding travel of the second dog tooth 42 to an engaging position with the first dog tooth 41 are formed at opposing ends of these dog teeth 41, 42.

Description

technical field [0001] The present invention relates to a dog clutch mainly used in a switching device of a multi-stage transmission, in particular to a dog clutch composed of a first dog clutch part, a second dog clutch part and a damping spring, and the first and second dog clutches are moderated by the damping spring The improvement of the claw clutch of the torque impact when the parts are engaged, wherein the first claw clutch part is connected to the rotating transmission part with a relative rotation clearance, and the rotating transmission part is freely rotatably supported on on the transmission shaft; the second dog clutch part is slidably supported on the above transmission shaft, and can be engaged with and disengaged from the first dog clutch; the damping spring is installed on the above-mentioned rotation transmission part and the first The dog clutch members are elastically deformed within the range of the relative rotational gap by the torque generated between ...
