FIELD: machine building.SUBSTANCE: coupling device for mutual engagement contains clutch mechanism (63), which includes detail (62) and slide valve (61). Clutch mechanism (63) is made with possibility of engagement or tripping while relative displacement of detail (62) and slide valve (61) in axial direction. Coupling device contains transposable element (66), drive (70), spring transmission (71), recoil spring (72), stopper (73), control unit (74). Control unit (74) is created to make implementation of the first control possible to set drive force (70) equal to force in the first area while clutching mechanism (63). In case of halt state on a half way of clutch mechanism (63) as a result of the first control, implementation of the second control to install the drive force which is higher than the force of the first control. First area is a range, in which drive force in a position of stroke of moving element is higher than impelling power of a recoil spring, upon that the first area is a range, in which the drive force is less than the sum of impelling power of recoil spring in a position of stroke and maximum impelling force, which is generated by transmission spring in a position of stroke when the movement of the slide valve is limited.EFFECT: decreasing of noise collision because of collision between moving element and stopper.5 cl, 15 dwg |
