JP 2005-297756 A

  By the way, the conventional shift operation device for a vehicle transmission is connected to the shift mechanism via a cable or the like and transmits the shift operation force of the shift lever to the transmission mechanism of the vehicle transmission. A shift operation force transmission member is provided so as to be interlocked with the operation in the shift direction of the lever. In Patent Document 1, a shift operation force transmission protrusion (engagement portion) formed on a lever body of a shift lever is inserted into a fitting hole formed on a control lever corresponding to the shift operation force transmission member. When the shift lever is operated in the shift direction, the shift operation force transmission projection and the fitting hole are engaged with each other, and the operation force of the shift lever is applied to the transmission mechanism via the control lever and the cable in sequence. It is to be transmitted. When the shift lever is operated in the select direction, the shift operation force transmission projection and the fitting hole are relatively inserted and removed so that the operation force of the shift lever is not transmitted to the control lever. Yes.

  Further, in the shift operation device of Patent Document 1, in order to restrict the rotation of the shift lever in the upright state (vertical state) about the axis of the shift lever, the shift operation rotation shaft extends from the base end portion of the shift lever in the upright state. A regulating lever projecting in the center direction and a seat member functioning as an outer ring of the spherical plain bearing, in order to receive the regulating lever, have a longitudinal shape in a direction parallel to the shaft of the shift lever in the upright state. And a lever receiving groove formed in. In such a shift operation device, when the shift lever in an upright state tries to rotate around the axis, the restriction lever engages with the lever receiving groove to prevent the shift lever from rotating around the axis. It has become. When the shift lever in the upright state rotates in the select direction, the regulating lever slides in the longitudinal direction of the lever receiving groove so that the shift lever rotates around the select operation rotation axis. It is allowed.

  However, in the shift operation device, the shift lever is engaged with the lever receiving groove when the shift lever is operated in the shift direction from the upright state and then operated in the select direction. Is moved in the select direction with rotation about its axis, so that the clearance between the shift operation force transmitting projection formed on the shift lever and the fitting hole formed on the control lever changes. It will be. Therefore, in order to prevent interference between the shift operation force transmission projection and the fitting hole when the shift lever is operated in the select direction, the opening width of the fitting hole is compared with the width of the shift operation force transmission projection. It needs to be set to some extent. For this reason, when the shift lever is operated in the shift direction, the shift operation force transmission protrusion of the shift lever and the fitting hole of the control lever increase, which causes deterioration of the shift feeling. .

  The present invention has been made in the background of the above circumstances, and an object of the present invention is to provide a shift operating device for a vehicle transmission that can improve shift feeling.

  In order to achieve the above object, the gist of the present invention is that (a) a shift operation rotation axis and a select operation rotation axis intersecting the shift operation rotation axis can be rotated. The base end portion is supported by a spherical plain bearing, and in order to switch the shift position of the vehicle transmission, any one of a plurality of operation positions set in advance corresponding to the plurality of shift positions of the vehicle transmission is selected. A shift operation device for a vehicle transmission including a shift lever operated in a shift direction and a select direction toward the shift direction, wherein (b) a base end portion of the shift lever has a spherical outer peripheral surface and the spherical slip Functions as an inner ring of the bearing, and (c) around the axis of the shift lever while allowing the shift lever to rotate about the shift operation rotation axis and the select operation rotation axis. The shift lever shaft and the base end of the shift lever when the shift lever is operated in the select direction regardless of the rotation position of the shift lever around the shift operation rotation axis. A rotation restricting mechanism that keeps the angle of intersection with the rotation axis constant.

  In this way, even when the shift lever is operated in the select direction after being operated in the shift direction from the upright state, the shift lever can be moved in the select direction without rotating around its axis. . Therefore, the engagement state between the shift lever and the shift operation force transmission member for transmitting the operation force in the shift direction of the shift lever to the transmission mechanism of the vehicle transmission does not change. That is, for example, the engagement force of the shift lever in the shift direction is caused by the engagement between the fitting hole formed in the shift lever and the shift operation force transmission projection provided in the fitting hole from the shift operation force transmission member. In the case of being configured to be transmitted, the clearance between the shift operation force transmission protrusion and the fitting hole does not change when the shift lever is operated in the select direction. Therefore, even if the clearance between the shift operation force transmission projection and the fitting hole is set to be small, the shift operation force transmission projection and the fitting hole when the shift lever is operated in the select direction. Since interference is suppressed, the clearance can be set small to improve the shift feeling.

  Preferably, the rotation restricting mechanism includes an engagement groove formed at a base end portion of the shift lever, and an engagement protrusion protruding from the outer ring of the spherical plain bearing into the engagement groove. With. In this way, regardless of the rotational position of the shift lever about the shift operation pivot axis, the shaft of the shift lever and the rotation of the base end of the shift lever when the shift lever is operated in the select direction. The crossing angle with the dynamic axis can be kept constant.

  Preferably, the rotation restricting mechanism is formed on an engagement protrusion protruding from a base end portion of the shift lever in a direction of the select operation rotation axis and an outer ring of the spherical plain bearing. And an engaging groove with which the engaging protrusion is engaged. In this way, regardless of the rotational position of the shift lever about the shift operation pivot axis, the shaft of the shift lever and the rotation of the base end of the shift lever when the shift lever is operated in the select direction. The crossing angle with the dynamic axis can be kept constant.

  Preferably, (a) the shift lever is moved along a plurality of operation paths provided between the plurality of operation positions, and (b) two or more of the plurality of operation paths are (C) engaging the fitting hole formed in the shift lever and the circumferential direction around the shift operation rotation axis when the shift lever is moved in the shift direction. And a shift operation force transmission projection that can be inserted into and removed from the fitting hole in a circumferential direction around the select operation rotation axis when the shift lever is moved in the select direction. A shift operation force transmission member for transmitting the operation force of the shift lever that is moved to the vehicle transmission to the vehicle transmission. In this way, not only the shift lever in the upright state, but also in a shift operation device in which the shift lever is operated in the select direction in other states, that is, the shift lever is moved in the shift direction from the upright state, The lever is moved in the select direction without rotating around its axis. Therefore, when the shift lever is operated in the select direction, the clearance between the fitting hole formed in the shift lever and the shift operation force transmission protrusion formed in the shift operation force transmission member does not change. Therefore, even if the clearance between the shift operation force transmission projection and the fitting hole is set to be small, the shift operation force transmission projection and the fitting hole when the shift lever is operated in the select direction. Since interference is suppressed, the shift feeling can be improved by setting the clearance small.

It has an axial center C3 and a concentric shaft part 14e that connect the tip part 14b. The shift operation force transmission member 16 is configured so that the shift lever 14 moves in the shift direction when the shift lever 14 moves along the first operation path 30, the second operation path 31, and the third operation path 33. When it is moved, it can be engaged with the fitting hole 36 formed in the plate-like portion 14d of the shift lever 14 in the circumferential direction around the shift operation rotation axis C2, and the shift lever 14 is moved in the select direction.

The engaging protrusions 40 respectively have a pair of sliding contact surfaces 40a that are opposed to the pair of side surfaces of the engaging groove 38 in the front-rear direction of the vehicle and that each have an arc shape in the cross section shown in FIG. The rotation restricting mechanism 42 allows the shift lever 14 to rotate about the shift operation rotation axis C1 and the select operation rotation axis C2 by the engagement of the engagement grooves 38 and the engagement protrusions 40. However, the rotation of the shift lever 14 about the axis C3 is restricted, and the shift lever 14 has its axis C3 and its shift regardless of the rotation position of the shift lever 14 about the shift operation rotation axis C1. The lever 14 has a function of maintaining an orthogonal state with the rotation axis C2 of the base end portion 14a when operated in the select direction. As described above, regardless of the operation position of the shift lever 14 in the shift direction, the axis C3 of the shift lever 14 and the rotation axis of the base end portion 14a, that is, the selection operation rotation axis C2 are kept orthogonal. As a result, the shift lever 14 is moved in the select direction without rotating around its axis C3, regardless of the shift operation position from which the shift lever 14 is operated in the select direction. Note that restricting the rotation of the shift lever 14 about the axis C3 means that the shift lever 14 rotates about the axis C3 orthogonal to the shift operation rotation axis C1 and the select operation rotation axis C2. It means to regulate.

  According to the shift operation device 10 for a vehicle transmission of the present embodiment, the vehicle rotates about a shift operation rotation axis C1 and a select operation rotation axis C2 orthogonal to the shift operation rotation axis C1. The base end portion 14a is supported by the spherical plain bearing 18 as possible, and any one of a plurality of operation positions set in advance corresponding to the plurality of shift positions of the vehicle transmission for switching the shift position of the vehicle transmission. 1 is a shift operating device 10 for a vehicle transmission including a shift lever 14 that is operated in the shift direction and the select direction toward the wheel 1. A base end portion 14a of the shift lever 14 has a spherical outer peripheral surface 26. It functions as an inner ring of the spherical plain bearing 18 and allows the shift lever 14 to rotate about the shift operation rotation axis C1 and the select operation rotation axis C2. Regardless of the rotation position of the shift lever 14 around the axis C1 of the shift lever 14 and the position of the shift lever 14 about the axis C1 of the shift operation, the axis C3 of the shift lever 14 and the shift lever 14 A rotation restricting mechanism 42 is provided that maintains a state orthogonal to the rotation axis C2 of the base end portion 14a of the shift lever 14 when operated in the select direction. By doing so, the shift lever 14 is moved in the select direction without rotating around its axis C3, regardless of which shift operation position the shift lever 14 is operated in the select direction. Therefore, the engagement state between the shift lever 14 and the shift operation force transmission member 16 for transmitting the operation force in the shift direction of the shift lever 14 to the transmission mechanism of the vehicle transmission does not change. That is, when the shift lever 14 is operated in the select direction, the clearance between the fitting hole 36 formed in the shift lever and the shift operation force transmission protrusion 16c formed in the shift operation force transmission member 16 changes. do not do. Therefore, even if the clearance between the shift operation force transmission protrusion 16c and the fitting hole 36 is set to be small, the shift operation force transmission protrusion 16c is fitted when the shift lever 14 is operated in the select direction. Since interference with the joint hole 36 is suppressed, the clearance can be set small to improve the shift feeling.

  Further, according to the shift operation device 10 of the vehicle transmission of the present embodiment, the rotation restricting mechanism 42 includes the engagement groove 38 formed in the base end portion 14 a of the shift lever 14 and the outer ring of the spherical plain bearing 18. 24 and an engaging protrusion 40 protruding from the engaging groove 38 in the engaging groove 38. In this way, regardless of the rotational position of the shift lever 14 about the shift operation pivot axis C1, the shift lever 14 when the axis C3 of the shift lever 14 and the shift lever 14 are operated in the select direction. It is possible to maintain an orthogonal state with the rotation axis C2 of the 14 base end portions 14a.

  Further, according to the shift operation device 10 for a vehicle transmission of the present embodiment, the shift lever 14 is moved along the plurality of operation paths 30 to 35 provided between the plurality of operation positions, Four of the operation paths 30 to 35 have an operation path in the select direction, and when the shift lever 14 is moved in the shift direction, the fitting hole 36 formed in the shift lever 14 and the shift operation cycle. Engageable in the circumferential direction around the dynamic axis C1, and can be inserted into and removed from the fitting hole 36 in the circumferential direction around the select operation rotation axis C2 when the shift lever 14 is moved in the select direction. A shift operation force transmission member 16 having a shift operation force transmission protrusion 16c and transmitting the operation force of the shift lever 14 moved in the shift direction to the vehicle transmission is provided. . Thus, not only when the shift lever 14 is in the upright state, but also in other states, that is, when the shift lever 14 is moved in the shift direction from the upright state, the shift lever 14 is operated in the select direction. The shift lever 14 is moved in the select direction without rotating around the axis C3. Therefore, when the shift lever 14 is operated in the select direction, there is a clearance between the fitting hole 36 formed in the shift lever 14 and the shift operation force transmission protrusion 16 c formed in the shift operation force transmission member 16. It does not change. Therefore, even if the clearance between the shift operation force transmission protrusion 16c and the fitting hole 36 is set to be small, the shift operation force transmission protrusion 16c is fitted when the shift lever 14 is operated in the select direction. Since interference with the joint hole 36 is suppressed, the shift feeling can be improved by setting the clearance small.

  Next, another embodiment of the present invention will be described. In the following description of the embodiments, portions common to the embodiments are denoted by the same reference numerals and description thereof is omitted.

The lever 14 has a function of maintaining an orthogonal state with the rotation axis C2 of the base end portion 14a when operated in the select direction. In FIG. 4, the shift lever 14 in a state of being rotated from the upright state indicated by the solid line around the shift operation rotation axis C <b> 1 to the parking operation position “P” is indicated by a two-dot chain line. .

  According to the shift operation device 50 for a vehicle transmission of the present embodiment, the vehicle rotates about the shift operation rotation axis C1 and the select operation rotation axis C2 orthogonal to the shift operation rotation axis C1. The base end portion 14a is supported by the spherical plain bearing 18 as possible, and any one of a plurality of operation positions set in advance corresponding to the plurality of shift positions of the vehicle transmission for switching the shift position of the vehicle transmission. A shift operating device 50 for a vehicle transmission having a shift lever 14 that is operated in the shift direction and the select direction toward the wheel 1, and a base end portion 14a of the shift lever 14 has a spherical outer peripheral surface 26. It functions as an inner ring of the spherical plain bearing 18 and allows the shift lever 14 to rotate about the shift operation rotation axis C1 and the select operation rotation axis C2. Regardless of the rotation position of the shift lever 14 around the axis C1 of the shift lever 14 and the position of the shift lever 14 about the axis C1 of the shift operation, the axis C3 of the shift lever 14 and the shift lever 14 A rotation restricting mechanism 58 is provided that maintains a state orthogonal to the rotation axis C2 of the base end portion 14a of the shift lever 14 when operated in the select direction. By doing so, the shift lever 14 is moved in the select direction without rotating around its axis C3, regardless of which shift operation position the shift lever 14 is operated in the select direction. Therefore, the engagement state between the shift lever 14 and the shift operation force transmission member 16 for transmitting the operation force in the shift direction of the shift lever 14 to the transmission mechanism of the vehicle transmission does not change. That is, when the shift lever 14 is operated in the select direction, the clearance between the fitting hole 36 formed in the shift lever and the shift operation force transmission protrusion 16c formed in the shift operation force transmission member 16 changes. do not do. Therefore, even if the clearance between the shift operation force transmission protrusion 16c and the fitting hole 36 is set to be small, the shift operation force transmission protrusion 16c is fitted when the shift lever 14 is operated in the select direction. Since the interference with the joint hole 36 is suppressed, the shift feeling can be improved by setting the clearance as small as in the first embodiment.

Moved to. Therefore, when the shift lever 14 is operated in the select direction, there is a clearance between the fitting hole 36 formed in the shift lever 14 and the shift operation force transmission protrusion 16 c formed in the shift operation force transmission member 16. It does not change. Therefore, even if the clearance between the shift operation force transmission protrusion 16c and the fitting hole 36 is set to be small, the shift operation force transmission protrusion 16c is fitted when the shift lever 14 is operated in the select direction. Since the interference with the joint hole 36 is suppressed, the shift feeling can be improved by setting the clearance as small as in the first embodiment.

  As mentioned above, although one Example of this invention was described in detail with reference to drawings, this invention is not limited to this Example, It can implement in another aspect.

  For example, in the above-described embodiment, the shift operation device 10 is a floor shift type that is fixed to a floor of a passenger compartment or a floor console installed on the floor, but is not limited thereto. For example, other types such as a column shift type and an instrument panel shift type may be used.

  Further, in the above-described embodiment, the engaging groove 38 is provided in the plate-like portion 14d of the shift lever 14, and the engaging protrusion 40 is provided in the main body portion 16a of the shift operation force transmitting member 16, Not only this but the engagement protrusion 40 may be provided in the plate-shaped part 14d, and the engagement groove 38 may be provided in the main-body part 16a.

  In the above-described embodiment, the shift lever 14 is configured such that the axis C3 of the shift lever 14 is parallel to the direction perpendicular to the floor surface when the shift lever 14 is positioned at the drive operation position “D”. However, the present invention is not limited to this, and the shaft center C3 of the shift lever 14 may be configured to be parallel to the direction perpendicular to the floor surface when the shift lever 14 is positioned at another operation position.

  It should be noted that the above description is merely an embodiment, and other examples are not illustrated. However, the present invention is implemented in variously modified and improved modes based on the knowledge of those skilled in the art without departing from the gist of the present invention. Can do.
