Particularly in the case of helical gears, the shape of the helical gear is inclined at an angle so that it is difficult to manufacture, and the tooth is inclined so that thrust is applied in the axial direction. This thrust means a propulsion force generated by the rotation of the propeller or the reaction to the gas injection, etc., which can be generated by the shape of the helical gear.

On the other hand, the bevel gear 37 is a gear that transfers motion between two axes in a conical shape at right angles and an obtuse angle, and has a kind of a straight bevel gear, a curved bevel gear, and a zero roll bevel gear.

In particular, the Xerol bevel gear may be substituted for the helical gear since the thrust direction is not changed even if the rotation direction is changed, so that the force in the thrust direction is small.

In addition, by using the bevel gear 37 it is possible to increase the gear ratio to improve the operating performance according to the dual clutch transmission gear actuator assembly according to the present invention.

In addition, when the release shaft assembly 30 is integrally fixed to both wall surfaces of the housing 20 due to the structure of the bevel gear 37, not only the structure of the housing 20 but also the structural wall surface of the bevel gear 37 may be provided. Easy to attach, there is an advantage to reduce the vibration during the operation of the release shaft assembly 30, and to enable a stable operation.

The bevel gear 37 is rotated by the shift pinion shaft 14, and the bevel gear 37 is connected by a pin 16 formed in a bearing that is coupled between the engagement of the shift pinion shaft 14.

As the bevel gear 37 rotates, a shift screw 34 that is rotated is further included to form the release shaft assembly 30.

Referring to the drawings, the housing 20 surrounds the drive unit and the release shaft assembly 30, and the release shaft assembly 30 is formed to be fixed to both walls as a single body. In this way, the release shaft assembly 30 is integrally fixed to both walls of the housing 20 so that the release shaft 36 assembly is fixed to the housing 20 through the integration of the housing guide structure in which the housing shaft and the bolt are fixed to the housing holder. The removal of parts such as bolts has the effect of reducing the number of parts and reducing the production cost through light weight.

In addition, the integrated housing guide structure to reduce the shake during operation according to the drive unit, it is possible to solve the problem of malfunction caused by separation and separation by weakening the coupling force of the housing holder and the bolt according to the guide structure.
