[0001]
BACKGROUND OF THE INVENTION
  The present invention provides an attachment of a shift lock cable provided in a shift lock device of an automatic transmission that prohibits a shift operation from a parking position of a shift lever to another swing position unless a predetermined operation is performed by a driver.ConstructionAbout.
[0002]
[Prior art]
An automatic transmission mounted on a vehicle is provided with a plurality of ranges such as P, R, N, D, S, and L, for example, and these ranges are selected by a shift lever swinging operation by a driver. However, this type of automatic transmission is provided with a shift lock device for preventing the vehicle from starting unexpectedly due to an inadvertent shift operation from the P range to the travel range such as the D range. It is done.
[0003]
This shift lock device is generally arranged on the side of the driver's seat, etc., and is arranged below the steering handle in front of the driver's seat and the shift operation portion including the shift lever, and the driver can rotate the start key. A cable is arranged so as to be movable in the axial direction between the key operation unit to be operated and the key is rotated to a rotation position (LOCK) where the start key can be removed from the key cylinder provided in the key operation unit. When the operation is performed, the movement of the cable is restricted, and the shift lever at the P range position is prohibited from swinging from the P range position to another range position, while the engine is started. When the start key is rotated to other rotation positions including START), the movement restriction of the cable is released and the shift lever is moved from the P range position to another range position. It is configured to permit tilting operation.
[0004]
In addition to the cable lock mechanism in the key operation section as described above, this type of shift lock device includes a brake that restricts the movement of the cable in the axial direction when the brake pedal is not depressed for further safety. An operation-linked cable lock mechanism is usually provided, so that, for example, the cable can only move when the engine is started and the brake pedal is depressed, and the shift lever is moved from the P range position. It can be swung to another range position.
[0005]
In that case, a shift lock cable mounting structure in the key operation unit is disclosed in Japanese Utility Model Laid-Open No. 5-7527. In this mounting structure, as shown in FIG. 11, one end of the cable b is inserted in the axial direction with respect to the case member a containing the key cylinder, and then fixed with a clip c. The outer cable of the cable b is provided with a mounting plug d, and the mounting plug d is locked to the opening e of the case member a. A slider f is connected to an inner cable provided in the outer cable so as to be movable in the axial direction. The slider f is moved in the axial direction by a rotating member that rotates integrally with the key cylinder in the case member a. The movement is restricted or allowed.
[0006]
[Problems to be solved by the invention]
By the way, in the shift lock cable mounting structure disclosed in the above publication, the shift lock cable is inserted into the case member in the axial direction and mounted. Therefore, the shift lock cable is attached to the case member with a force along the axial direction thereof. Then, the cable is likely to buckle during the attaching operation, and the operation is difficult, and the cable may be damaged.
[0007]
Of course, in the case of the technology disclosed in the above publication, it is only necessary to carry out the cable mounting operation with the plug provided in the outer cable in hand. Usually, the key operation unit to which this type of shift lock cable is mounted is the driver's seat. Located below the front steering handle, the shift lock cable extends from the shift operation section along the steering column and then reaches the case member supported on the top of the steering column. Since this cable is attached in such a manner that it protrudes from the surface on the engine room side of the case member, it is possible to visually confirm the attachment part directly from the driver's seat side in the installation work of the cable. In addition, the installation work must be performed by turning the arm from the driver's seat side to the engine room side surface of the case member. For must, at the momentum it becomes often perform mounting operation in hand on the cable itself directly rather than through a plug of the cable end.
[0008]
Therefore, the present invention addresses the above-described problems in the conventional shift lock device, and an object of the present invention is to improve the workability of installing the shift lock cable in the key operation unit.

[0021]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below.
[0022]
FIG. 1 is an overall schematic configuration diagram of a shift lock device in an automatic transmission according to the present embodiment. This shift lock device includes a shift lever 1 that can swing in a vehicle front-rear direction, and is provided by a driver. By swinging the lever 1, P (parking position), R (reverse position), N (neutral position), D (1st to 4th automatic shift position), S (1st to 3rd speed) are sequentially operated from the front side of the vehicle. On the lower surface of the relatively upper part of the steering column 4 that rotatably supports the steering handle 3 and the shift operation unit 2 for selecting each range of L (automatic shift position) and L (1st to 2nd automatic shift positions). The key operation unit 6 is arranged so that the start key 5 is rotated to a plurality of rotation positions by the driver, and is disposed between the shift operation unit 2 and the key operation unit 6 so as to be movable in the axial direction. A shift lock cable 7, When the start key 5 is in the LOCK position where the key operation unit 6 can be removed, the movement of the cable 7 in the axial direction is restricted by the key operation unit 6, and the shift lever 1 P in the shift operation unit 2 is controlled. While operation from one range to another range is prohibited, when the start key 5 is in the other Acc (accessory), ON (engine electrical system on) or START (engine start) rotation position, the cable 7 The movement restriction is released, and the shift lever 1 can be operated from the P range to another range.
[0023]
In addition to the cable lock device in the key operation unit 6 described above, this shift lock device restricts the movement of the cable 7 in the axial direction when the brake pedal 8 is not depressed. A brake pedal-linked cable lock device 9 that operates so as to release the restriction is provided, so that the start key 5 is located at a rotational position other than the LOCK position in the key operation unit 6 and the brake pedal is operated. Only when 8 is depressed, the shift operation unit 2 is allowed to operate the shift lever 1 from the P range to another range.
[0024]
When the shift lever 1 in the shift operation unit 2 is operated to push the shift button 1b provided on the handle portion 1a at the upper part thereof, the shift pin 1c provided at the lower part thereof moves downward in the direction of the arrow A, while the shift button 1 When the pushing operation of 1b is released, the shift pin 1c is moved upward in the direction of arrow B. Particularly when the shift lever 1 is in the P range, the shifting pin 1c is moved downward by the pushing operation of the shift button 1b. Then, the cable 7 is moved in the arrow C direction by an interlocking mechanism (not shown), while the cable 7 is moved in the arrow D direction when the shift pin 1c is moved upward by releasing the pressing operation of the shift button 1b. ing. The shift lever 1 is not operated by pushing the shift button 1b to move the shift pin 1c downward, in other words, the shift lock cable 7 does not move in the C direction. Abutting on the member, the swing operation cannot be performed from the P range to another D range or the like.
[0025]
Next, the configuration of the cable lock device in the key operation unit 6 which is a feature of the present invention will be described. As shown in FIG. 2, the key operation unit 6 includes a case member 11 supported by a fastening member (not shown) on the lower surface of the steering column 4 at a relatively upper portion. The case member 11 is provided with a key cylinder 12 which is operated in accordance with the turning operation of the start key 5, and the right end of the case member 11 faces the driver's seat and faces rightward and obliquely upward. It is the end on the insertion port side. An end portion of the cable 7 guided to the key operation portion 6 extends from below to above along the steering column 4 and reaches the case member 11.
[0026]
FIG. 3 is a bottom view of the case member 11. In the drawing, the upper side is the driver's seat side (hereinafter referred to as the front for convenience) and the lower side is the engine room side (also referred to as the rear). In the central portion of the lower surface of the case member 11, there is an accommodating portion 13 at the end of the cable 7 extending at a predetermined inclination angle with respect to the case member 11 and parallel to the longitudinal direction of the steering column 4. Is provided. 4 and 5, the housing portion 13 is fixed to the lower surface of the case member 11 with bolts 14 and 15, respectively, and a pair of front and rear hollow mounting members 16 and 17 whose lower surfaces are open. And a hollow housing member 18 that is assembled to the mounting members 16 and 17 from below and has an upper surface opened. The inner space formed by the mounting members 16 and 17 and the housing member 18 The end of the cable 7 is accommodated.
[0027]
The shift lock cable 7 includes an outer cable 7a and an inner cable 7b movable within the outer cable 7a, and an attachment member 7c is provided at the end of the outer cable 7a. The end of the shift lock cable 7 is incorporated on the housing member 18 side as a whole. A substantially rectangular parallelepiped block body 19 is connected to the tip of the inner cable 7b. The block body 19 is a pair of front and rear protrusions provided on the upper surfaces 16a and 17a of the mounting members 16 and 17 in the housing portion 13. In a state of being sandwiched between the T-shaped rails 16 b and 17 b and the lower surface 18 a of the housing member 18, it slides in the longitudinal direction of the housing portion 13.
[0028]
As described above, when the shift lever 1 is in the P range, when the shift button 1b is pushed, the shift pin 1c is moved downward and the inner cable 7b moves in the direction of the arrow C. While the body 19 is located at a substantially middle portion of the accommodating portion 13 as indicated by a chain line in FIG. 4, the pressing operation of the shift button 1b is released, whereby the shift pin 1c is moved upward and the inner cable 7b is moved. When it moves in the direction of arrow D, it is located in the front part of the accommodating part 13 as shown by the solid line in FIG.
[0029]
The mutually opposing end portions of the upper surfaces 16a and 17a of the pair of front and rear mounting members 16 and 17 are bent upward, and the bent portions cause the mounting members 16 and 17 or the housing portion 13 to have a predetermined inclination. A groove portion 20 extending in parallel with the longitudinal direction of the case member 11 is formed at an angle, and a substantially rectangular parallelepiped regulating member 21 is fitted in the groove portion 20 so as to be movable. The lower surface of the regulating member 21 does not protrude downward from the T-shaped rails 16b and 17b so as not to interfere with the sliding in the arrow C and D directions of the block body 19 connected to the inner cable 7b. A projecting portion 22 that protrudes downward from the T-shaped rails 16 b and 17 b and can interfere with the sliding of the block body 19 is formed on the key cylinder 12 side.
[0030]
In this case, the end surface 22 a of the protrusion 22 on the side opposite to the key cylinder 12 is formed in parallel with the longitudinal direction of the housing portion 13 or the side surface of the block body 19, and the block body 19 is in front of the housing portion 13. A corner portion of the block body 19 that faces the protrusion 22 when positioned at a portion is chamfered by a surface 19 a parallel to the moving direction of the restricting member 21 or the side surface of the protrusion 22.
[0031]
Further, an action shaft member 23 extending to the inside of the case member 11 beyond the groove portion 20 formed at the opposed end portions of the mounting members 16 and 17 is fixed to the end portion of the restriction member 21 on the key cylinder 12 side. At the same time, a spring 24 is interposed between the end of the restricting member 21 on the side opposite to the key cylinder 12 and the case member 11, and the restricting member 21 or the action shaft member 23 is moved by the spring 24 to the key cylinder 12. Is biased in the direction. Inside the case member 11 from which the action shaft member 23 extends, a cam member 25 that rotates integrally with the key cylinder 12 by the operation of the key cylinder 12 in accordance with the key operation of the driver is housed.
[0032]
The cam member 25 has a rotation shaft 25 a that extends in the longitudinal direction of the case member 11 in the same direction as the movement direction of the regulating member 21 and is provided coaxially with the rotation axis of the start key 5 or the key cylinder 12. The end face cam is provided at a right angle to the rotation shaft 25a and has a predetermined profile formed on the surface on the side opposite to the key cylinder, and the action of the end of the regulating member 21 on the cam face. The shaft member 23 is always in pressure contact with the urging force of the spring 24.
[0033]
As shown in FIG. 6, when the cam member 25 is rotated to the LOCK position where the start key 5 can be removed, the cam member 25 has a thick part (part with a large lift amount) 25 b on the cam surface. As a result, the regulating member 21 moves in the anti-key cylinder direction against the urging force of the spring 24 via the working shaft member 23 as shown by a solid line in FIG. On the other hand, when the start key 5 is rotated from the Lock position to the Acc position, ON position or START position as indicated by an arrow in the figure, the portion of the cam surface with a small thickness (lift amount) 25c and the action shaft member 23 come into contact with each other. As a result, the restricting member 21 is pressed by the urging force of the spring 24 as shown by a chain line in FIG. Rotates so as to move in the da direction.
[0034]
In this case, when the start key 5 is rotated to the LOCK position and the restricting member 21 is moved to the position opposite to the key cylinder, the protrusion 22 of the restricting member 21 interferes with the block body 19 of the shift lock cable 7. Then, the block member 19 moves on the sliding path of the block body 19 so as to prevent the block body 19 from sliding or the cable 7 from moving. When 21 moves to a position in the key cylinder direction, the protrusion 22 retracts from the sliding path of the block body 19 to allow the block body 19 to slide or the cable 7 to move. In FIG. 6, a hatched portion 25d on the cam surface of the cam member 25 is a slope that transitions between a portion 25b having a large lift amount and a portion 25c having a small lift amount.
[0035]
Next, the operation of this shift lock device will be described.
[0036]
Now, the vehicle is stopped and the engine is to be started. At this time, the shift lever 1 is in the P range position, and the key cylinder 12 is rotated to the lock position where the start key 5 can be extracted and is in the extracted state. Therefore, the shift lock cable 7 has moved in the D direction, and the block body 19 connected to the end of the cable 7 led into the case member 11 of the key operation unit 6 is shown in FIG. As shown by the solid line in FIG. 4, the restricting member 21 is moved in the anti-key cylinder direction as shown by the solid line in FIG. 4 as the cam member 25 is rotated via the key cylinder 12. Then, the protrusion 22 has advanced on the sliding path of the block body 19.
[0037]
Therefore, if the shift lever 1 is swung from the P range to another range such as the D range in this state, even if the shift button 1b is pressed, the block body 19 remains on the sliding path. Since the movement of the inner cable 7b is restricted by contacting the projection 22 of the restricting member 21 that has advanced to the contact surface 19a, and the shift operation portion 2 is prevented from interlocking with the shift pin 1c of the interlock mechanism, the shift The shift pin 1c in the lever 1 cannot be moved downward, and as a result, the shift lever 1 cannot be shifted from the P range to another range. As a result, it is prohibited to operate the shift lever 1 from the P range to the travel range before starting the engine or the like, and the situation where the vehicle unexpectedly starts is avoided.
[0038]
Next, when the engine is started by rotating the start key 5 to the START position, the cam member 25 is rotated through the key cylinder 12 in accordance with the rotation operation of the key 5, and is shown by a chain line in FIG. As described above, the restricting member 21 moves in the key cylinder direction, and the protrusion 22 retracts from the sliding path of the block body 19. However, the movement restriction of the block body 19 or the cable 7 has not been released yet, and the cable 7 can move in the C direction only after the brake pedal 8 is depressed. As a result, the shift lever 1 is swung in the traveling range direction such as the D range in a state where the brake pedal 8 is depressed, and the unexpected start is more effectively avoided.
[0039]
When the shift lever 1 is swung from the P range to another range, the cable 7 stops in a state of moving in the C direction, and the block body 19 in the case member 11 is shown by a chain line in FIG. It stops at an intermediate part of the accommodating part 13. At this time, the block body 19 stops in a state of crossing the groove portion 20 formed between the attachment members 16 and 17, and as a result, the retracted position (on the key cylinder side) of the regulating member 21 moving along the groove portion 20 is stopped. ) From the advanced position (counter key cylinder side position) is prevented by the contact between the side surface of the block body 19 and the end surface 22a of the projection 22 of the regulating member 21 parallel to the side surface. It will be. Thereby, if the shift lever 1 is not operated to the P range, a key interlock for prohibiting the extraction of the start key 5 is realized.
[0040]
In that case, the abutment between the block body 19 and the protrusion 22 of the restricting member 21 at the time of the shift lock and the key interlock is abutted by the surfaces 19a and 22a parallel to the other side surface, respectively. Such a contact surface 19a, 22a is not provided, and the problem that the contact force is concentrated at one point of the corner portion and the other side surface or member is damaged is avoided as in the case of contact at the corner portion. become.
[0041]
In the key operation unit 6, the cam member 25 included in the case member 11 serves as an end face cam, the rotation axis of the start key 5, the rotation axis of the key cylinder 12, and the cam. A movement path of a regulating member 21 that is set to be coaxial with the turning shaft 25a of the member 25 and that is moved so as to restrict or release the movement of the cable 7 by turning the cam member 25; In other words, since the extending direction of the groove portion 20 formed by the opposed end portions of the pair of front and rear mounting members 16 and 17 is provided in parallel to the rotation axis, the movement path of the regulating member 21 is rotated. The diameter of the case member 11 can be made smaller than in the case where the case member 11 is provided in a direction orthogonal to the axis. As shown in FIGS. 1 and 2, the case member 11 is disposed below the steering handle 3 so that the longitudinal direction thereof is substantially horizontal. Therefore, as shown by an arrow E in the figure, for example, a knee protector or the like is used. A larger space is secured in the lower space of the steering column 4 where other members are arranged, and the layout around the key operation unit 6 is improved.
[0042]
Next, a configuration relating to the assembly of the mounting members 16 and 17 and the housing member 18 constituting the housing portion 13 will be described with reference to the enlarged views of FIGS. 4 and 5 and FIGS.
[0043]
First, the mounting members 16 and 17 include upper surfaces 16a and 17a on which the T-shaped rails 16b and 17b are formed, and wall portions 16c and 16c; 17c and 17c extending downward from the side edges of the upper surfaces 16a and 17a, respectively. The front end wall portion 16c ′ of the front mounting member 16 is provided with a notch 16d. On the other hand, the rear portion of the rear mounting member 17 is expanded in the width direction, and the central portion of the rear end wall portion 17d is a notch 17e having a width substantially equal to the width of the side edge wall portions 16c, 16c; 17c, 17c. And a rectangular recess 17f is formed around the notch 17e on the outer surface of the rear end wall 17d.
[0044]
On the other hand, the housing member 18 has a flat lower surface 18a and wall portions 18b, 18b extending upward from the side edge of the lower surface 18a, and is engaged with the notch 16d of the mounting member 16 from the front end. A matching claw portion 18c is provided. On the other hand, on both side portions in a portion near the rear end portion, recesses 18e and 18e extending in the vertical direction and fitting with the notch 17e of the rear end wall portion 17d of the mounting member 17 are formed. Further, notches 18f and 18f extending from the upper end portion to the lower surface 18a are provided in the wall portions 18b and 18b on both sides in a portion slightly ahead of the recesses 18e and 18e.
[0045]
The accommodating member 18 is configured such that the front part of the notches 18f and 18f is outside the attachment members 16 and 17, and the rear part of the notches 18f and 18f is the extension end 17g of the attachment member 17 at the rear. It is assembled so as to be located inside each. In that case, the notches 18f and 18f of the housing member 18 straddle the extended end portion 17g of the rear mounting member 17, and the notch 16d of the front mounting member 16 and the claw portion 18c of the housing member 18 are engaged. In addition, the notch 17e of the rear end wall portion 17d in the rear mounting member 17 and the concave portions 18e, 18e of the accommodating member 18 are fitted to each other, and the concave portion 17f of the rear end wall portion 17d in the mounting member 17 is fitted. Further, a part of the rear end portion 18g in which the cable 7 extends outward from the recesses 18e and 18e in the housing member 18 is fitted.
[0046]
In this state, the clip 31 provided with the leaf spring portions 31a, 31a having a forward biasing force is provided on the inner surface of the rear end wall portion 17d of the rear mounting member 17 and the recesses 18e, 18e, whereby the accommodating member 18 is urged forward and fixed relative to the mounting members 16, 17, and the accommodating portion 13 is configured by these members 16, 17, 18. .
[0047]
Next, a method for assembling the housing member 18 to the attachment members 16 and 17, in other words, a method for attaching the shift lock cable 7 to the case member 11 will be described with reference to FIG.
[0048]
First, one end of the shift lock cable 7 is first housed in the housing member 18, and the housing member 18 is attached with the mounting members 16, 17 as indicated by an arrow F in FIG. It is made to face from below. In this case, the recesses 18e and 18e of the housing member 18 are fitted into the notches 17e in the rear end wall portion 17d of the rear mounting member 17, and the notches 18f and 18f of the housing member 18 are extended ends of the mounting member 17. It abuts so as to straddle the portion 17g.
[0049]
In this case, since the shift lock cable 7 is housed in the housing member 18 by a predetermined length in the axial direction along the length direction of the housing member 18, the housing member 18 is attached to the mounting members 16, 17 or the case. When the lower surface of the member 11 is brought into contact with the lower surface from the lower side, an axial force does not act on the cable 7 and there is no possibility that the cable 7 is buckled.
[0050]
When the housing member 18 is horizontally moved forward as indicated by an arrow G in FIG. 10 from this state, the recesses 18e and 18e of the housing member 18 are fitted into the notches 17e of the mounting member 17 as described above. In addition, the claw portion 18c of the housing member 18 is engaged with the notch 16d of the front mounting member 16 with the notches 18f and 18f of the housing member 18 straddling the extended end portion 17g of the mounting member 17. In addition, the front surface of the rear end portion 18g of the housing member 18 is fitted into the concave portion 17f of the mounting member 17. Therefore, the housing member 18 that is in contact with the lower side is locked to the case member 11 at two positions on the front and rear sides, so that the housing member 18 does not fall down. It can be done easily.

Thereafter, the clip 31 is inserted into the space formed between the inner surface of the rear end wall portion 17d of the rear mounting member 17 and the recesses 18e, 18e of the housing member 18, and the housing member 18 is inserted into the mounting member 16, 17 to the case member 11.
[0052]
In this embodiment, as shown in FIG. 1 or FIG. 2, after the shift lock cable 7 extends from the engine room side along the steering column 4 to the driver seat side, It is led from the engine room side. Therefore, when the end portion of the cable 7 is pushed into the case member 11 in the axial direction, the cable 7 is likely to buckle, and when the operator works from the driver's seat side, the attachment site is on the back side. As a result, visual confirmation is not possible and the operation is difficult. On the other hand, in the configuration of the key operation unit 6, the cable 7 is similarly attached so as to protrude outward from the back side of the case member 11. The assembly direction of the cable 7 is the axial direction of the cable 7. Instead, as described above, since it is in the direction intersecting with the axial direction of the cable 7, in addition to the occurrence of buckling, the mounting portion is not disposed on the back side but is disposed on the lower surface or side surface. Therefore, the work can be visually confirmed, and the work is facilitated.

【The invention's effect】
As described above, according to the present invention, the shift lock cable is attached to the case body in a state where one end of the shift lock cable is accommodated in the accommodation member by a predetermined length.
[0054]
  In this case, the housing member is attached to the case body from the direction intersecting the axial direction of one end of the cable. Therefore, when the cable is attached, the force along the axial direction of the cable does not act on the cable. As a result, the cable is unlikely to buckle during the mounting operation, so that the mounting workability is improved and damage to the cable is avoided.In that case, the abutment between the block body and the regulating member abuts at a contact surface parallel to the other side surface. The problem that the contact force concentrates on one point of the corner and the other side surface or member is damaged is avoided.
[0055]
In particular, when the housing member is attached to the lower part of the case body from below, the case of the housing member is provided by providing a temporarily engaging portion for temporarily fastening the housing member to the case body. At the time of attachment to the main body, after the housing member is brought into contact with the case body from below, the housing member can be temporarily fixed to the case main body by the engaging portion. Even if it is released, the housing member or cable does not fall, and the mounting operation becomes easier.
