4 is a view showing the cover 30 of the vehicular transmission 1 according to the embodiment of the present invention.

The vehicular transmission (1) according to an embodiment of the present invention has two different shift detection modes. This can be expressed by the first shift sensing mode and the second shift sensing mode. The first shift sensing mode is a rotary mode in which the vehicular transmission 1 of the present invention is used, such as a rotary type transmission, by operating the knob 11 by rotating the lever 12 about the rotation axis. The second shift sensing mode is a mode in which the joystick 12 is shifted in the forward / backward direction by rotating the lever 12 about an axis which is different from the rotation axis, Mode.

In order to switch between the two different shift sensing modes, the vehicular transmission 1 according to the present invention is configured to surround the region where the lever 12 and the knob 11 are located, and the knob 11 and the lever moving portion 50 The mode switching button 32 may be further included in the cover 30 formed between the cover 30 and the cover 30. A signal is transmitted to the motor 41 in response to the depression of the mode switching button 32 to select the rotary mode and the joystick mode. The operation of the motor 41 in response to the signal transmission of the mode switching button 32 will be described later in detail with reference to FIG.

Or a button for setting the P-speed range stage. In this case, the speed change stage selected by the lever 12 can be made in the order of RND.

4, the parking button 31 and the mode switching button 32 are formed on one side of the cover 30. However, the position of the button is not limited thereto.

5 to 8, a description will be given of a process in which the lever moving part 50 and the lever 12 of the vehicular transmission 1 according to the embodiment of the present invention ascend and descend.

5 is a view showing the internal structure of the lever moving part 50 of the vehicular transmission 1 according to the embodiment of the present invention. 6 is a perspective view showing a rotation nut 40 used in the vehicular transmission 1 according to the embodiment of the present invention. 7 is a view showing the lead screw 70 and the lever 12 used in the vehicular transmission 1 according to the embodiment of the present invention. 8 is a perspective view of the internal structure of the vehicular transmission 1 according to the embodiment of the present invention viewed from the bottom.

The rotary nut 40, the motor 41 and the lever 12 are accommodated in the lever moving part 50 as described above. 5, not all of the lever 12 is shown, but only the rotary bullet 14, which is a portion accommodated in the lever moving portion 50, is shown.

The lever moving part 50 is connected to the rotary groove 52 at one end and to the lever moving body 57 at the other end by a rotary groove 52 swinging vertically upward and downward according to the lateral movement of the rotary bullet 14, A rotary groove spring 51 which is connected to the lever moving part 50 and provides an elastic force so that the rotary groove 52 can swing with respect to the lever moving body 57, a lever moving part cover 53 which is the upper and lower surfaces of the lever moving part 50, And a lever moving part bottom 56, and a lever moving part body 57 covering the whole. The rocking motion of the rotary groove 52 will be described in detail in the description of the rotary mode and the joystick mode.

The control signal is transmitted to the motor 41 accommodated by the lever moving section 50 by depressing the mode switching button 32 described above. The motor 41 is rotated in a predetermined direction in accordance with a control signal to ascend or descend and the worm 43 connected to the drive shaft 42 of the motor 41 rotates the worm wheel formed on the outer circumferential surface 401 of the rotary nut . The motor 41 of the present invention is preferably a DC motor 41, but the type of the motor 41 is not limited thereto.

Referring to FIG. 6, the structure of the rotation nut 40 can be confirmed in more detail. The rotary nut 40 is formed in the shape of a torus similar to a general nut, and on the inner circumferential surface, threads are formed in the longitudinal direction like a general nut. The thread is formed in the form of a female thread corresponding to the thread 71 of the lead screw 70.

However, the outer circumferential surface 401 of the rotary nut is formed with threads different from those of a general nut so as to have a worm wheel structure corresponding to the thread of the worm 43 connected to the drive shaft 42 of the motor 41.

The inner circumferential surface 402 of the rotation nut is engaged with the lead screw 70 and the outer circumferential surface 401 of the rotation nut is engaged with the worm 43 connected to the motor 41, 43 rotate, the rotary nut 40, which receives the rotational force, rotates. Since the lead screw 70 is fixed to the lower housing 22, the rotary nut 40, which receives the rotational force, moves up and down while rotating on the lead screw 70.

The rotary nut 40 is restrained in the lever moving part 50 in the upper and lower directions, but is rotatably supported around the lead screw 70 which is a rotary shaft. Accordingly, the lever moving part 50 also ascends and descends due to the rotating nut 40 moving up and down.

The rotary bullet 14 clamped and fixed between the lever moving portion cover 53 and the rotary groove 52 at an upper portion of the lever moving portion 50 is also lifted and lowered do.

Referring to FIG. 7, the relationship between the lead screw 70 and the lever 12 can be confirmed. The knob 11 can be connected to one end of the lever 12 in one direction so that the rotary bullet 14, the rotary magnet 80, A lever function portion 13 including a lever 15 is formed. Other configurations of the lever function unit 13 will be described later in the description of the rotary mode and in the direction in which the rotary bullet 14 is formed in Fig.

The rotary bullet 14 is a cylindrical element formed at the end of the lever 12 in the direction orthogonal to the longitudinal direction of the lever 12. A rotary magnet 80 to be described later may be formed at a position opposite to the position where the rotary bullet 14 is formed.

The lead screw 70 is centered along the longitudinal direction so that the lever 12 can be inserted, and the space thus opened in the longitudinal direction is referred to as hollow. One end is opened to allow the lever 12 to be inserted, and the other end is fixed to the lower housing 22. [ The lead screw 70 is fixed vertically upward and a screw thread 71 is formed on the outer circumferential surface so that the rotary nut 40 rotates along the thread 71 on the lead screw 70 and rotates vertically up and down, (70) in the longitudinal direction.

A screw groove 72 opened to the outside may be formed at one side of the outer circumferential surface of the lead screw 70 and a lower end of the screw groove 72 may include an extended portion 73 extending along the outer circumferential direction, A 'T' shaped screw groove 72 can be formed. Further, the screw groove 72 may be formed in a shape symmetrical to the opposite surface symmetrical about the rotational axis of the lead screw 70 as well.

The rotary bullet 14 of the lever 12 is inserted into the screw groove 72 thus opened. The lever 12 is inserted into the lead screw 70 and the rotary bullet 14 is inserted into the screw groove 72 so that the lever 12 is prevented from rotating in the hollow within a predetermined angle do. Since the rotary bullet 14 is regulated by the screw groove 72 when the lever 12 ascends and descends in the hollow, the screw groove 72 can be the rising and falling guide lines of the lever 12. [ That is, the rotary bullet 14 can move along the inverted 'T' shaped screw groove 72.

5, the rotary bullet 14 inserted into the screw groove 72 is sandwiched between the rotary groove 52 and the lever moving portion cover 53 constituting the lever moving portion 50 as described above. Thus, the lever moving part 50 receives the lever 12.

The lever moving part 50 moves upward and downward along the longitudinal direction of the lead screw 70 due to the movement of the rotating nut 40 rotated by the motor 41 so that the lever moving part 50 is supported by the constituent elements of the lever moving part 50 The rotary bullet 14 is also moved in the same direction as the lever moving part 50. Since the rotary bullet 14 is a component of the lever 12, the lever 12 is moved in the same direction by the same amount of movement as the rotary bullet 14 moves. That is, the lever 12 ascends and descends along the longitudinal direction of the lead screw 70 by the rotation of the motor 41.

Through the above-described process, the lever moving part 50 and the lever 12 of the vehicular transmission 1 can be moved. In one embodiment of the present invention, the first position P1 and the second position P2 are located at positions that the lever moving part 50 and the lever 12 can reach by moving in the vertical direction, exist.

The first position P1 is a position at which the vehicular transmission 1 can perform the shift according to the first shift sensing mode, i.e., the rotary mode. When the rotary bullet 14 reaches a position extending along the outer circumferential direction at the lowermost one of the thread grooves 72 of the lead screw 70, the first position P1 is reached.

The second position P2 is a position at which the vehicular transmission 1 can perform the shift according to the second shift sensing mode, i.e., the joystick mode. When the rotary bullet 14 is positioned in the upper region of the thread groove 72 and the rotary magnet 80 and the joystick rod 15 are inserted into the groove roller 60 to be described later, It is.

Hereinafter, how the shift sensing is performed in the first shift sensing mode, i.e., the rotary mode, will be described with reference to FIGS.

9 is a front view showing a state of the lever moving part 50 in the rotary mode of the vehicular transmission 1 according to the embodiment of the present invention. 10 is a perspective view showing a rotary mode of the vehicular transmission 1 according to the embodiment of the present invention. 11 shows the position of the knob 11 in the rotary mode of the vehicle transmission 1 according to the embodiment of the present invention.

When the lever moving part 50 and the lever 12 are positioned at the first position P1, the knob 11 is positioned in close contact with the cover 30 as shown in FIG. Therefore, it is more suitable for the operator to operate the knob 11 in a rotary type than to operate the knob 11 in a joystick manner.

The lever 12 coupled to the knob 11 rotates in the same direction as the knob 11 as the driver rotates the knob 11 for shifting about the rotation axis parallel to the longitudinal direction of the lead screw 70. [ .

A lever function portion 14 is formed at one end of the lever 12 that is not engaged with the knob. The lever function unit 14 has the rotary bullet 14 described above at one end and the rotary magnet 80 described above at the other end. And further includes a joystick rod 15 to be described later between the rotary bullet 14 and the rotary magnet 80. [ The lever function portion 14 gives a feeling of operation to the driver by the action of the rotary bullet 14 when the lever 12 is located at the first position Pl and the lever 12 is moved to the second position The lever 12 is rotated by the action of the joystick rod 15 and the rotary magnet 80. [

As the lever 12 rotates, the rotary bullet 14 located at the end of the lever 12 rotates in the same direction. Since the thread groove 72 of the lead screw 70 extends on the outer peripheral surface along the direction in which the lever 12 rotates, the range in which the rotary bullet 14 can rotate is determined.

The rotary bullet 14 is supported between the rotary groove 52 and the lever moving portion cover 53 constituting the lever moving portion 50 as described above. Therefore, an external force acts on the components supporting the rotary bullet 14 as the rotary bullet 14 rotates. The rotary bullet 14 is brought into contact with the rotary groove surface 521 formed in the center region of the rotary groove 52 so that the rotary bullet 14 will rise on the rotary groove surface 521 as the rotary bullet 14 moves in one direction, As a result, a force is applied to the rotary groove 52 by the rotary bullet 14 downward. Since the rotary groove 52 is pivotally supported by the lever moving part 50 via the rotary groove spring 51, the rotary groove 52 is moved downward by the received external force.

The rotary groove surface 521 is a surface which is formed in a shape of 'V' in which two oblique faces formed in opposite directions from the center of the rotary groove 52 meet. The lower side of the rotary bullet 14 is supported by the rotary groove surface 521 and the upper side thereof is supported by the lower surface of the lever moving section cover 53. Therefore, the rotary bullet 14 moves along the rotary groove surface 521 during the rotation. The rotary bullet 14 is basically located in the valley formed at the center of the rotary groove surface 521 in a state in which no external force is applied.

The rotary groove surface 521 is not formed of an oblique surface maintaining a constant inclination over the entire surface, but is formed as an oblique surface having a different inclination depending on the section. The slope of the oblique plane varies from section to section so that the user feels a sense of theft when the user rotates the knob 11, and the force required to rotate the rotary bullet 14 changes. Accordingly, the user can know how much the knob 11 should be rotated for changing.

A rotary magnet (80) is formed at one end of the lever function unit (14). Therefore, the rotary magnet 80 also rotates in accordance with the rotation of the rotary bullet 14 about the rotation axis parallel to the longitudinal direction of the lead screw 70. [ The rotary magnet 80 is made of a material having magnetism. The vehicle transmission 1 according to the present invention includes a 3D hall sensor (not shown) as a first magnetic force sensor disposed on a substrate (not shown) connected to the side surfaces of the upper housing 21 and the lower housing 22, It is possible to measure the intensity of the magnetic field which changes in accordance with the rotation of the magnet 80. The 3D Hall sensor may be disposed at a position adjacent to the rotary magnet 80. [ From the intensity of the magnetic field thus measured, the user can see how much the knob 11 and the lever 12 have been rotated. The substrate has a speed change stage at which the user wants to move from the rotation amount calculated from the sensor value of the 3D hall sensor And transmits the control signal to the transmission (not shown).

The rotary groove 52 is moved downward by an external force, and the rotary groove spring 51 is compressed and exerts an elastic force in the opposite direction to be compressed. The rotary groove 52 is pushed upward by the elastic force received from the rotary groove spring 51 and the rotary groove 52 is located on the rotary groove surface 521. Therefore, when the driver stops the external force acting on the knob 11 after the shift is completed, The rotary bullet 14 returns to the center of the rotary groove surface 521 along the inclination of the rotary groove surface 521. [ In this way, after the operator operates the knob 11 in the rotary mode, the knob 11 returns to its original position. A shift device that causes the knob 11 to return to its original position as in the rotary mode of the present invention is referred to as a stable type transmission. By configuring the knob 11 to return to the original position, the components used for the speed change operation can be made compact and lightweight without becoming large.

Hereinafter, how the shift sensing is performed in the second shift sensing mode, i.e., the joystick mode, will be described with reference to FIGS. 12 to 14. FIG.

12 is a front view showing a state of the lever moving part 50 in the joystick mode of the vehicular transmission 1 according to the embodiment of the present invention. FIG. 13 is a perspective view showing an operating state in the joystick mode of the vehicular transmission 1 according to the embodiment of the present invention. 14 shows the position of the knob 11 in the joystick mode of the vehicle transmission 1 according to the embodiment of the present invention.

The rotary magnet 80 and the joystick rod 15 are moved to the inside of the groove roller 60 when the lever moving part 50 and the lever 12 reach the second position P2 by the operation of the motor 41 Respectively. The rotary magnet 80 and the joystick rod 15 can be seated inside the groove roller 60. The rotary magnet 80 and the joystick rod 15 can be positioned inside the groove roller 60, The inner surface is formed.

As the rotary magnet 80 and the joystick rod 15 are seated in the groove roller 60, the upward movement of the rotary bullet 14 and the lever 12 connected thereto is limited from this point. However, the motor 41 further operates for a predetermined time after this point to rotate and lift the rotary nut 40. [ The rotary moving part 50 is moved up and down as the rotary nut 40 moves up and down. The rotary groove 52 and the lever moving part cover 53, which support the rotary bullet 14 in the upper and lower directions, Since the rotary magnet 80 and the groove roller 60 are regulated upwardly, they can not move up and down any further. Therefore, only the lever moving body 57 and the lever moving floor 56 are further raised and pressed to press the rotary groove spring 51. When the lever moving body 57 and the lever moving floor 56 are raised and lowered to the point where the rotary groove spring 51 can not be further pressed, the motor 41 is stopped. The lever moving unit 50 and the lever 12 finally reach the second position P2 in which the shifting of the joystick mode can be performed in the second speed change sensing mode. Fig. 12 shows a state in which the rotary groove spring 51 is compressed by reaching the second position P2.

The lever moving body 57 may further include a protrusion 55 inserted into the through hole formed in the lever moving cover 53. [ As the projecting portion 55 and the through hole 531 are slidably engaged, the lever moving body 57 and the lever moving portion cover 53 can be engaged. The protruding portion 55 is slidable with respect to the through hole 531 so that the lever moving portion body 57 is brought into close contact with the lever moving portion cover 53 as the lever moving portion 50 reaches the second position P2 And to be slid upward when brought into contact. The protrusion 55 may prevent the protrusion 55 from separating from the through hole 531 by fastening a bolt whose diameter is larger than the diameter of the protrusion 55, but this is not shown. The protrusions 55 and the through holes 531 are formed in the same number at the corresponding positions, and four protrusions 55 are formed in one embodiment of the present invention, but the number is not limited thereto.

When the lever moving part 50 reaches the second position P2, the knob 11 and the lever 12 are protruded upward as shown in Fig. 14 so that the operator can push the knob 11 in the same manner as the lever or the joystick Thereby making it easy to operate.

The operator applies an external force to the knob 11 for shifting along the direction in which the joystick rod 15 is rotated about the rotation axis parallel to the direction in which the joystick rod 15 is extended so that the lever 12 coupled to the knob 11 rotates about the rotation axis And is rotated about the center.

As the lever 12 rotates, the joystick rod 15 located at the end of the lever 12 becomes the rotation axis and simultaneously rotates in the same direction. As the joystick rod 15 rotates, the adjacent rotary magnet 80 rotates and the groove rollers 60, which receive the rotary magnet 80 and the joystick rod 15, rotate in the same direction .

The rotary magnet 80 and the joystick rod 15 are formed in a cylindrical shape so that the inner surface of the groove roller 60 is formed to have a cylindrical shape corresponding to the rotary magnet 80. In this case, And the joystick rod 15 rotate, the groove roller 60 may not receive sufficient frictional force or may not rotate because there is no point where it can receive an external force. Therefore, in an embodiment of the present invention, the rotary magnet 80 includes the engaging portion 801 formed as a rod-shaped handle on the surface connected to the joystick rod 15, and the inner surface of the groove roller 60 is also corresponding So that the latching portion 801 is inserted. The joystick rod 15 having the joystick rod 15 as its rotation axis and the inner surface of the groove roller 60 when the rotary magnet 80 is rotated receive a force of rotation by the engagement portion 801, ) Can be rotated in the same manner.

On both sides of the groove roller 60, a joystick groove surface 601 may be formed. Similar to the rotary groove surface 521, the joystick groove surface 601 is a surface that is formed in a 'V' shape by two oblique faces formed in opposite directions from the center. The joystick groove surface 601 is brought into contact with one end of the joystick bullet 62. The joystick bullet 62 is supported in the bullet housing 63 supported by the upper housing 21 or the side housing (not shown) so that one end thereof is swingable by the joystick spring and the other end is engaged with the joystick groove surface 601 . The joystick groove surface 601 is supported by the joystick bullet 62 and the joystick groove surface 601 moves the joystick bullet 62 against the bullet housing 63 as the groove roller 60 rotates It becomes a form of squeezing. At the same time, the joystick bullet 62 can be seen as moving relatively along the joystick groove surface 601. The joystick bullet 62 is basically located in the valley formed at the center of the joystick groove surface 601 in the state where no external force is applied. Although the joystick bullet 62, the bullet housing 63, and the joystick spring are shown as being formed around the groove roller 60 for stable operation in the embodiment of the present invention, the number is not limited thereto, Only one may be formed.

The joystick groove surface 601 is not formed of an oblique surface maintaining a constant inclination over the entirety, but is formed as an oblique surface having a different inclination depending on the section. The slope of the oblique surface varies from section to section so that the user feels a sense of theft when an external force is applied to the knob 11, and the force required to rotate the groove roller 60 changes. Accordingly, the user can know how much external force should be exerted on the knob 11 just for changing.

When the joystick bullet 62 receives an external force from the joystick groove surface 601 in accordance with the rotation of the groove roller 60, an elastic force is generated in a direction opposite to the direction in which the joystick spring is compressed. The joystick bullet 62 is pushed by the elastic force and the joystick bullet 62 is pushed by the external force applied to the joystick groove face 601 The groove roller 60 rotates to its original position and returns. In this manner, after the operator operates the knob 11 in the joystick mode, the knob 11 returns to its original position. Therefore, it is possible to implement a stable type shift device in the same manner as the rotary mode even in the joystick mode.

A roller tooth 61 is formed on an outer circumferential surface of the groove roller 60 and a joystick magnet 81 formed on the outer circumferential surface of a tooth to be engaged with the roller tooth 61 is rotatably supported by a side housing do. The joystick magnet 81 is made of a magnetic material and forms a magnetic field. As the groove roller 60 rotates, the joystick magnet 81 engaged with the groove roller 60 rotates.

A second hall sensor (not shown) as a second magnetic force sensor is disposed on a substrate (not shown) connected to the side surfaces of the upper housing 21 and the lower housing 22, It is possible to measure the intensity of the magnetic field which changes in accordance with the rotation of the magnet 81. From the intensity of the magnetic field thus measured, the user can see how much the knob 11 and the lever 12 have been rotated. The substrate has a speed change stage at which the user wants to move from the rotation amount calculated from the sensor value of the 2D hall sensor And transmits the control signal to the transmission (not shown).
