Description

Technical Field [0001] The present invention relates to a gear actuator apparatus for a manual transmission,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gear actuator device of a manual transmission, and more particularly, to a gear actuator device of a manual transmission capable of detecting an initial reference point for shift and selection with minimum operation.

Research is being actively carried out to improve fuel efficiency and environmentally friendly automobiles worldwide. Transmissions are also a trend to replace conventional manual transmissions with automated manual transmissions and dual clutch transmissions instead of automatic transmissions to improve fuel economy. To automate these manual transmissions, an actuator is required to shift the gears, and most of the actuators are of the motor type.

The automated manual transmission drives a finger that moves the shift lug along a shift or select direction with a gear actuator. A technique related to this gear actuator is disclosed in Korean Patent Laid-Open No. 10-2012-0133762.

The conventional memory actuator includes a housing which forms a space for operation and installation inside, a first motor for select operation, a second motor for shift operation, a first motor and a second motor, A select operation unit provided on the first motor and the speed change shaft for linearly moving the speed change shaft by the power of the first motor; And a shift operation unit that rotates the shift shaft to a predetermined position.

On the other hand, the transmission must be in a neutral state when the engine is turned on or off. The gear actuator that performs the shifting in the shift pattern shown in Fig. 1 must be located at the reference point.

As described above, the conventional gear actuator is provided with a shift shaft that is inserted through the housing and a structure that is provided in the housing to position the shift shaft, which performs the shifting action in the gear actuator, at the reference point of the shift pattern.

That is, the structure for positioning the speed change shaft at the reference point of the speed change pattern includes a finger member at an end portion of a speed change shaft provided in the housing, and for measuring a moving distance of the finger member for positioning the finger member at a reference point, And a pair of guide pins provided at predetermined distances from each other.

The above-described shift shaft is positioned at the reference point, and the selection reference point is detected and the shift reference point is detected.

First, in the select reference point detection process, when the control unit moves the speed change shaft and the finger member provided on the speed change shaft is not moved in close contact with the bottom surface of the housing, it is determined that the finger member is positioned at the reference point of the speed change pattern.

In the shift reference point detection process, the control unit rotates the shift shaft. Then, the finger members are rotated between the pair of guide pins spaced apart at a predetermined angle interval provided on the bottom surface of the housing. At this time, the controller detects the position when the finger member is rotated and moved to one of the pair of guide pins to contact the guide pin, rotates the finger member again, The center position of the pair of guide pins detected after the detection is calculated, and then the guide pin is positioned at the center position to determine the shift reference point.

As described above, in the process of detecting the shift reference point for the shift operation, the second motor for the shift operation is driven to rotate the shift shaft to one side, and after detecting the position of the guide pin on one side, The shift shaft is rotated counterclockwise to detect the position of the other guide pin, and then the center position between the guide pins is calculated to detect the shift reference point. Thus, the process is complicated and a separate pair of guides There is a problem that cost increases due to an increase in parts.
