Japanese Patent Laid-Open No. 7-35224

  By the way, in order to prevent the shift lever and the like from rattling, it is not yet known, but a bearing member such as a soft plastic part is interposed between the side plate of the base member and the shift shaft, and the shift shaft is pivoted. It is conceivable to push in the direction, but when the shift lever is rotated to the manual increase / decrease position such as + position and-position around the axis of the shift shaft at the connection release position (manual mode position, etc.) As in the case of operating to the shift operation position, sliding resistance is generated on the shift shaft. For this reason, if the shift lever is automatically returned to the connection release position by the biasing means such as a spring, it is necessary to apply a large biasing force corresponding to the sliding resistance. There was a problem that the resistance was increased and the operability was impaired.

  The present invention has been made against the background of the above circumstances, and an object of the present invention is to make it possible to prevent rattling of the shift lever or the like by the bearing member without impairing the operability of the shift lever. .

  In order to achieve such an object, the present invention provides: (a) a base member that has a pair of side plates and is integrally fixed to the vehicle body; and (b) straddling the pair of side plates and rotating around an axis. (C) a shift shaft disposed so as to be rotatable about the axis of the shift shaft, and mechanically moved by being rotated about the axis of the shift shaft. A control member for switching the transmission to (d) a select shaft that can be rotated integrally with the shift shaft about the axis of the shift shaft, and (e) that can be rotated about the axis of the select shaft. A shift lever disposed; and (f) provided in association with the shift lever and the control member, and when the shift lever is operated to a connecting position around the axis of the select shaft, The control member and the phase around the axis of the shift shaft When connected to the non-rotatable position and operated to the disengagement position around the axis of the select shaft, the connection between the shift lever and the control member is released to allow relative rotation around the axis of the shift shaft. And (g) the shift lever is operated to a plurality of shift operation positions around the axis of the shift shaft in a state where the shift lever is held at the connection position, so that the control member can When the transmission is switched and the shift lever is operated to the connection release position in the connection release allowable operation position among the plurality of shift operation positions, only the shift lever is moved without rotating the control member. In a vehicle shift lever device that is allowed to rotate around the axis of the shift shaft, (h) between the shift shaft and the side plate. And a bearing member that prevents the rattling by pressing the shift shaft in the axial direction by its own elasticity by being compressed and deformed, and (i) the bearing member and the side plate or the shift shaft One and the other of the contact surfaces are provided with protrusions and recesses that can be fitted to each other when the shift lever is operated to the connection release allowable operation position. The bearing member presses the shift shaft with a large pressing force by climbing to a portion other than the recess, but the protrusion enters the recess at the connection release allowable operation position, and the pressing force applied from the bearing member to the shift shaft is reduced. It is characterized by being.

  According to such a vehicle shift lever device, when the shift shaft is pressed in the axial direction by the bearing member, rattling of the shift shaft, the shift lever and the like is prevented, and generation of abnormal noise is prevented. In the release-permitted operation position, the protrusion enters the recess and the pressing force applied to the shift shaft from the bearing member, that is, the sliding resistance of the shift shaft is reduced. Therefore, the shift lever is moved around the axis of the shift shaft at the release position. The operability when rotating is improved. For example, when the shift lever is automatically turned back and forth from a manual increase / decrease position, etc., determined around the axis of the shift shaft to a connection release position by a biasing means such as a spring, the sliding resistance of the shift shaft is small. Therefore, it can be smoothly returned with a relatively small urging force, and the operation resistance when operating the shift lever to the manual increase / decrease position or the like is reduced, so that excellent operability can be obtained.

  Here, the vehicle shift lever device of the present invention is disposed, for example, in the center console portion next to the driver's seat, but can be disposed in various parts near the driver's seat such as an instrument panel and a steering column. It is. When disposed on the center console portion or the instrument panel, the shift shaft is disposed, for example, so as to be substantially horizontal and substantially parallel to the width direction of the vehicle. It is set as appropriate according to the arrangement site.

  In the present invention, as described in Patent Document 1, a cylindrical shift shaft is used, and a select shaft is provided at a right angle to the shift shaft at a position where the shift shaft is twisted. The shift shaft may be arranged adjacent to the axial direction of the shift shaft so as to be rotatable around the axis of the shift shaft, but a solid shift shaft may be used or selected so as to intersect the shift shaft at a right angle. Various modes are possible, such as providing a shaft or using a control member having a retainer fitted to the outside of the shift shaft so as to be relatively rotatable. The select shaft is preferably disposed in a posture that is substantially perpendicular to the shift shaft, but may be slightly inclined from the perpendicular direction.

  In the case of a planetary gear type automatic transmission having a plurality of hydraulic friction engagement devices, the control member is mechanically connected to the transmission via, for example, a cable or a link. By switching, a neutral state that cuts off power transmission, a forward traveling state that engages a hydraulic friction engagement device for forward traveling, and a reverse traveling state that engages a hydraulic friction engagement device for backward traveling It is comprised so that may be materialized. When the transmission has a mechanical parking lock mechanism, the mechanical parking lock mechanism can be mechanically operated to enter a parking state in which rotation of the output shaft is mechanically blocked. Various transmissions such as a two-shaft automatic transmission, a transmission that only switches forward and backward, and an automatic transmission that automatically switches a plurality of forward shift stages having different gear ratios can be adopted.

  A plurality of shift operation positions around the axis of the shift shaft include a P (parking) position that establishes the parking state, an N (neutral) position that establishes neutral, an R (reverse) position that establishes the reverse traveling state, and forward The connection release allowable operation position at which the shift lever can be operated from the connection position to the connection release position at the D (drive) position that establishes the traveling state is, for example, the D position.

  In the disengagement position, manual increase / decrease positions such as + position,-position, up position, down position, etc. are set on both sides around the axis of the shift shaft, and the shift lever is operated to such manual increase / decrease position. Depending on the number of operations and the operation time, various control operations such as changing the gear stage and speed range of the transmission, changing the size of the power source brake by regenerative braking of the engine brake and electric motor, etc. Is possible. The manual increase / decrease position may be either the increase side or the decrease side, or a predetermined operation position other than the manual increase / decrease position may be set. It is desirable that the return rotation of the shift lever from the operation position such as the manual increase / decrease position to the connection release position is automatically performed by an urging means such as a spring.

  The bearing member has, for example, a press-fit portion that is integrally fixed to the control member, and is rotated around the axis of the shift shaft integrally with the control member. A member is pressed in the axial direction of the shift shaft to prevent rattling. In this case, the protrusion and the recess are provided on the contact surface between the bearing member and the side plate, and the shift lever is disposed so as to be rotatable relative to the manual increase / decrease position with respect to the control member. .

  The bearing member also includes, for example, a press-fit cylindrical portion that is press-fitted into a mounting hole of the control member, and an outer flange that extends outward from one end of the press-fit cylindrical portion and is interposed between the control member and the side plate. An inner flange that extends inwardly from one end of the press-fit cylindrical portion and is interposed between the shift shaft and the side plate, and the control member is formed by compressing the outer flange and the inner flange, respectively. The shift shaft is pressed to prevent rattling. The press-fit cylindrical portion corresponds to the press-fit portion.

  The bearing member is integrally disposed on the side plate by press fitting or the like, and a protrusion and a recess are provided on the contact surface between the bearing member and the shift shaft, or the bearing member is integrally disposed at the end of the shift shaft by press fitting or the like. It is also possible to provide protrusions and recesses on the contact surface between the bearing member and the side plate, and in that case, when the shift lever is operated to an operation position such as a manual increase / decrease position at the connection release position. Since these protrusions and recesses are also relatively rotated, it is desirable to fit the protrusions and the recesses with a play allowing the relative rotation. Such play is not necessary when the bearing member is fixed to the control member.

  The bearing member does not necessarily have a cylindrical portion, and may be a flat disk-shaped bearing plate or the like, and various modes that can press the shift shaft by elastic deformation are possible. Further, the bearing member may be disposed at either one end portion in the axial direction of the shift shaft, but may be disposed at both end portions in the axial direction. In the case of using a stepped shift shaft whose diameter is changing, a bearing member can be disposed on the stepped portion. When a pair of bearing members are provided, the protrusions and recesses of the present invention can be provided on both of them, but only one of the protrusions and the recesses may be provided.

  The protrusions and the recesses are constituted by, for example, ridges and grooves provided in the radial direction with respect to the axis of the shift shaft. These ridges and grooves may be provided only one so as to be orthogonal to the shaft center, but various modes are possible, such as providing three or more radial shapes (e.g., equiangular intervals) around the shaft center. It is. In addition, it is desirable that at least one circumferential end surface that engages with each other is an inclined surface so that the protrusion can smoothly run on a portion other than the recess when it is relatively rotated around the axis. The protrusion and the recess may be provided on the bearing member side or may be provided with a recess.

  As a material of the bearing member, for example, a soft plastic material such as a polyester elastomer is preferably used, and a hardness of about 40 degrees to 70 degrees is appropriate. The allowance for protrusions and recesses (projection height) varies depending on the material (hardness, etc.) and thickness of the bearing member, but rattling and abnormal noise may occur with moderate sliding resistance (pressing force). For example, a thickness of about 0.5 to 1.5 mm is appropriate.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  The bearing bush 22 corresponds to a bearing member. In this embodiment, the bearing bush 22 is made of a soft plastic material (for example, polyester elastomer) having a hardness of about 50 degrees, and is formed in an opening at one end of the retainer 16a of the control member 16. A press-fit cylindrical portion 22a that is press-fitted and fixed, an outer flange 22b that extends outward from one end of the press-fit cylindrical portion 22a and is interposed between the retainer 16a and the side plate 12a, and extends inward from one end of the press-fit cylindrical portion 22a. And an inner flange 22c interposed between the main body 14a of the shift shaft 14 and the side plate 12a. When the outer flange 22b is compressed, the retainer 16a of the control member 16 is pressed in the axial direction and rightward in FIGS. 3 and 4 by its elasticity, and is rattled between the side plate 12b and the side plate 12b. To prevent. Further, when the inner flange 22c is compressed, the shift shaft 14 is pressed in the axial direction and rightward in FIGS. 3 and 4 due to its elasticity, and is sandwiched between the locking groove 26 of the side plate 12b.

It is held between the inner flange 22 c of the bush 22.

The control member 16 includes a control lever 16b, a detent lever 16c, and a clutch lever 16d that are integrally provided so as to extend outward from the cylindrical retainer 16a. The control lever 16b is provided so as to protrude below the floor of the vehicle body. For example, the control lever 16b is connected to a manual valve of a planetary gear type automatic transmission having a plurality of hydraulic friction engagement devices via a cable or a link. By rotating the shift shaft 14 about the axis O ₁ , the oil passage is mechanically switched by the manual valve, and a neutral state in which power transmission is interrupted and hydraulic pressure for forward traveling are output to output a plurality of The forward travel state in which the forward shift stage can be established and the reverse travel state in which the hydraulic friction engagement device for backward travel is engaged are established, and the mechanical parking lock mechanism is mechanically operated to output A parking state is established in which the rotation of the shaft is mechanically blocked. Detent lever 16c is uneven is provided along an arc around the axis O ₁ at its tip by the positioning member to the unevenness is brought resiliently engaged, the neutral state control member 16, forward Positioning is performed with moderation at four positions that establish the respective states of the traveling state, the reverse traveling state, and the parking state. Clutch lever 16d is an engaging projection 30 projecting the axis O ₁ at its distal end in a direction parallel and integrally provided with, by being engaged with the engagement hole 32 formed on the shift operating member 18 , to prevent relative rotation between the control member 16 and the shift operating member 18 in about the axis O _1, both are coupled to be rotated around integrally axis O _1. These engagement protrusions 30 and engagement holes 32 constitute a clutch device 34.

The shift operation member 18 is disposed on a select shaft 36 provided on the shift shaft 14 so as to be orthogonal to the shift shaft 14, and is rotated around the axis O ₁ of the shift shaft 14 integrally with the select shaft 36. At the same time, it can be rotated around the axis O ₂ of the select shaft 36. The select shaft 36 is disposed so as to penetrate an orthogonal hole 37 provided in the main body portion 14 a of the shift shaft 14, and both end portions thereof straddle the bifurcated leg portions 18 a and 18 b of the shift operation member 18. The clip 38 is positioned and is prevented from being pulled out by engaging the clip 38 assembled to one leg 18a with the head. The retainer 16a of the control member 16 avoids interference with the leg portions 18a and 18b, and allows the shift operation member 18 to rotate around the axis O ₂ of the select shaft 36 by a predetermined angle. A pair of notches 40a, 40b is provided.

The shift operation member 18 is integrally provided with a rod-shaped shift lever 42, and the tip of the shift operation member 18 protrudes upward from the base member 12 so that an operation knob is attached. The shift lever 42 is rotated about the axes O ₁ and O ₂ , and the moderation pin 46 urged in the protruding direction by the moderation spring 44 is formed in an uneven shape (not shown) formed in the base member 12. By engaging with the positioning engagement surface, the shift lever 42 is moderated at each of the operation positions P (parking), R (reverse), N (neutral), D (drive), and S (sequence) shown in FIG. Is positioned. FIG. 7 is a diagram showing a shift pattern of the shift lever 42. The shift lever 42 is moved along a moving route indicated by a solid line while being guided by a guide (not shown), and four operation positions P and R determined in the longitudinal direction of the vehicle. , N, and D, the clutch device 34 is rotated around the axis O ₁ of the shift shaft 14 while swinging around the axis O ₂ while maintaining the connection state with the control member 16. Then, the shift lever 42 is rotated about the axis O ₁ together with the control member 16 in this way, so that the parking state is mechanically established at the P position, and the reverse traveling state is mechanically established at the R position. In the N position, the neutral state is mechanically established, and in the D position, the forward traveling state is mechanically established. These operation positions P, R, N, and D correspond to shift operation positions.

Next to the operation position D, that is, the operation position S on the driver's seat side, the shift lever 42 is positioned by being rotated around the axis O ₂ of the select shaft 36. Since the position around O ₁ does not change, the automatic transmission is maintained in the forward traveling state in which a plurality of forward shift stages can be established. At this operation position S, the shift operation member 18 is rotated as shown by a one-dot chain line in FIG. 3, the engagement protrusion 30 is relatively removed from the engagement hole 32, the clutch device 34 is shut off, and the control member 16. is permitted to rotate only operate the shift lever 42 without rotating about the axis O ₁ about the axis O ₁ of the. As shown in FIG. 7, on both the front and rear sides of the S position, that is, around the axis O ₁ , a + position and a − position are set as manual increase / decrease positions at which the gear position can be electrically increased / decreased. Is rotated around the axis O ₁ and operated to such a manual increase / decrease position, this is detected by an ON-OFF switch or the like (not shown), and the shift stage of the automatic transmission or automatically shifts. A plurality of shift ranges having different shift ranges of the shift speeds to be moved up and down according to the number of operations and the operation duration time for the manual increase / decrease position. These + position and − position are unstable positions, and the shift lever 42 is automatically returned to the S position by the engagement between the moderation pin 46 and the positioning engagement surface. In this embodiment, the operation position D is a connection release allowable operation position around the axis O ₁ and a connection position around the axis O ₂ , and the operation position S is a connection release position around the axis O ₂ .

Here, an inner flange 22c of the bearing bush 22 is interposed between the shift shaft 14 and the side plate 12a, and the shift shaft 14 is pressed against the locking groove 26 of the opposite side plate 12b by the compression deformation of the inner flange 22c. Therefore, the shift shaft 14 and the shift operation member 18 disposed on the shift shaft 14 may rattle or generate abnormal noise due to vibrations during operation of the shift lever 42 or when the vehicle travels. It is suppressed. However, when the shift shaft 14 is pressed by the bearing bush 22 in this way, the sliding resistance of the shift shaft 14 increases, so that the operation resistance when the shift lever 42 is rotated around the axis O ₁ increases. . In this case, there is no problem between the operation positions P, R, N, D, and S where the driver manually moves, but the moderation pin 46 and the positioning engagement surface at the + position and the − position that are the manual increase / decrease positions. Since the shift lever 42 is automatically returned to the S position by engagement with the shift lever 42, if the sliding resistance of the shift shaft 14 increases, the set spring load of the moderation spring 44 is increased by the amount of the sliding resistance. It is necessary to apply an urging force, and accordingly, an operation resistance when the shift lever 42 is operated to the + position or the − position is increased.

On the other hand, in this embodiment, as shown in detail in FIGS. 5 and 6, a protrusion 50 is provided on the contact surface of the side plate 12 a that is brought into contact with the bearing bush 22. A concave groove 52 corresponding to the ridge 50 is provided on the contact surface of the bearing bush 22, that is, on the end surfaces of the outer flange 22 b and the inner flange 22 c. These ridges 50 and grooves 52 are provided so as to be orthogonal to the axis O ₁ of the shift shaft 14, and the shift lever 42 is operated to the D position around the axis O ₁ . Occasionally, the ridges 50 and the grooves 52 are in phase with each other and the ridges 50 enter the grooves 52, and the ridges 50 and the grooves 52 intersect at the P, R, and N positions. The strip 50 rides on the end face other than the concave groove 52. In order that the ridges 50 can smoothly ride on the grooves 52 when they are relatively rotated around the axis O ₁ , the side surfaces of these ridges 50 and the grooves 52, that is, the circumferences around the axis O _1. The direction end face is inclined. Further, the height of the ridges 50 and the depth of the concave grooves 52, that is, the tightening allowance when they are crossed, is the effect of preventing the occurrence of rattling or abnormal noise due to the elastic deformation of the flanges 22b and 22c. Is appropriately set within a range of 0.5 to 1.5 mm, for example, about 1.0 mm. The widths of the ridges 50 and the grooves 52 are substantially the same, and there is almost no play. In the present embodiment, the ridge 50 corresponds to a protrusion and the groove 52 corresponds to a recess. 5 (a) is a front view, (b) is a right side view, (c) is a bottom view, FIG. 6 (a) is a plan view, and (b) is a bottom view of (a). FIG.

  In the operation positions P, R, and N where the ridge 50 rides on the end face other than the groove 52 in this way, the deformation amount of the outer flange 22b and the inner flange 22c of the bearing bush 22 is large, and control is performed with a large pressing force. Since the member 16 and the shift shaft 14 are pressed in the axial direction, the occurrence of such rattling and abnormal noise can be satisfactorily prevented. Further, since the deformation amount of the bearing bush 22 is small at the D position and the S position where the ridge 50 enters the concave groove 52, the pressing force for pressing the control member 16 and the shift shaft 14 in the axial direction is reduced, and the shift shaft 14 sliding resistance is reduced. As a result, it is not necessary to increase the set spring load of the moderation spring 44 for automatically returning the shift lever 42 from the + position or the − position to the S position, and the shift lever 42 is operated to the + position or the − position. The operating resistance when doing so can be kept small. Even at the D position and the S position, the slight deformation of the inner flange 22c and the presence of the bearing plate 28 suppress the occurrence of rattling and abnormal noise of the shift shaft 14 and the shift lever 42. 2 to 4 show a state where the shift lever 42 is operated to the D position.

Thus, according to the vehicular shift lever device 10 of the present embodiment, the bearing 50 is formed by the protrusion 50 riding on the end face other than the groove 52 at each of the operation positions P, R, and N around the axis O _1. Since the deformation amount of the outer flange 22b and the inner flange 22c of the bush 22 is increased and the control member 16 and the shift shaft 14 are pressed in the axial direction with a large pressing force based on the deformation amount, the control member 16, the shift shaft 14, and the shift While the shift lever 42 and the like disposed on the shaft 14 are not rattled and the occurrence of abnormal noise is prevented well, the protrusion 50 enters the groove 52 at the D position (including the S position). As a result, the deformation amount of the outer flange 22b and the inner flange 22c is reduced, the pressing force is reduced, and the sliding resistance of the shift shaft 14 is reduced. The setting spring load of the moderation spring 44 for automatically returning 42 can be reduced, and the operation resistance when the shift lever 42 is operated to the + position or the − position is reduced, so that excellent operability can be obtained. .

  Although the control member 16 in the above embodiment is integrally formed of a synthetic resin material, a control member 60 made of metal such as steel can also be adopted as shown in FIG. The control member 60 has a control lever 60b and a clutch lever 60d, which are integrally formed, fixed to one end of a cylindrical retainer 60a by welding or the like, and a detent lever 60c on the other end of the retainer 60a. Are integrally fixed by welding or the like, and high mechanical strength is obtained. Therefore, it is preferably used when the control lever 60b or the like is exposed from the vehicle body to the outside. In this case, a synthetic resin bearing bush 62 is also provided on the side opposite to the side where the bearing bush 22 is provided to prevent metal contact with the shift shaft 14 and a request for the generation of abnormal noise. When the performance is high, it is desirable that the engaging protrusion 64 and the detent portion 66 are made of a synthetic resin material by insert molding or the like. The bearing bush 62 is provided with an oil groove for holding lubricating oil.

  As mentioned above, although the Example of this invention was described in detail based on drawing, this is an embodiment to the last, and this invention is implemented in the aspect which added various change and improvement based on the knowledge of those skilled in the art. Can do.

Claims (1)

A base member having a pair of side plates and integrally fixed to the vehicle body;
A shift shaft disposed so as to be rotatable around an axis centering over the pair of side plates;
A control member that is rotatably disposed about the axis of the shift shaft and mechanically switches the transmission by being rotated about the axis of the shift shaft;
A select shaft that is rotated around the axis of the shift shaft integrally with the shift shaft;
A shift lever arranged to be rotatable around the axis of the select shaft;
The shift lever and the control member are provided in association with each other, and when the shift lever is operated to a connection position around the axis of the select shaft, the shift lever and the control member are connected to the axis of the shift shaft. When the shift lever and the control member are operated to the connection release position around the axis of the select shaft, the connection between the shift lever and the control member is released. A clutch device that allows rotation;
And the shift lever is operated to a plurality of shift operation positions around the axis of the shift shaft in a state where the shift lever is held at the coupling position, whereby the transmission is switched by the control member, When the shift lever is operated to the connection release position at the connection release allowable operation position among the plurality of shift operation positions, only the shift lever is rotated around the axis of the shift shaft without rotating the control member. In a vehicle shift lever device that is allowed to be operated dynamically,
While having a bearing member that is interposed between the shift shaft and the side plate and is compressed and deformed to press the shift shaft in the axial direction with its own elasticity to prevent rattling,
One and the other of the contact surfaces between the bearing member and the side plate or the shift shaft are provided with protrusions and recesses that can be fitted to each other when the shift lever is operated to the connection release allowable operation position. The bearing member presses the shift shaft with a large pressing force when the protrusion rides on a portion other than the recess except in the connection release allowable operation position. However, the protrusion enters the recess in the connection release allowable operation position. A shift lever device for a vehicle, wherein a pressing force that enters and is applied to the shift shaft from the bearing member is reduced.
