Description

The present invention relates to the technical field of a range selection mechanism for locking a parking gear connected to a drive shaft of a vehicle.

In a vehicle having an automatic transmission, a shift lever is operated to select a range such as a parking range (P range), a reverse range (R range), a neutral range (N range), or a drive range (D range). Furthermore, some vehicles select a parking range by operating a parking switch.

The parking range is a range that maintains the vehicle in a stopped state, and when a selection operation to the parking range is performed using a shift lever or the like, the rotation of the drive shaft is restricted and the rotation of the drive wheels is disabled.

Transition to the parking range and cancellation of the parking range are performed by operating the range selection mechanism. The range selection mechanism operates in conjunction with a parking gear connected to the drive shaft, a parking pole that regulates the rotation of the parking gear, a parking rod that extends in the longitudinal direction of the vehicle and operates the parking pole, and a manual shaft that is connected to the parking rod. The parking pole is provided with a meshing portion that meshes with the parking gear.

When the selection operation to the parking range is performed, the manual shaft is rotated in a predetermined direction, the manual plate is rotated in a predetermined direction with the rotation of the manual shaft, and the manual plate is rotated in conjunction with the rotation of the manual plate. The parking rod is moved in a predetermined direction, and as the parking rod is moved, the parking pole is moved in a direction closer to the parking gear, and the meshing portion meshes with the parking gear to restrict rotation of the parking gear. When the rotation of the parking gear is restricted, the rotation of the drive shaft is restricted so that the drive wheels cannot rotate, and a transition to the parking range is performed.

Conversely, when a selection operation other than the parking range is performed, the manual shaft and manual plate are rotated in the opposite direction to the above, and the parking rod is moved in the opposite direction to the above in conjunction with the rotation of the manual plate. As the parking rod moves, the parking pole is moved in a direction away from the parking gear, the meshing portion of the meshing portion is disengaged from the parking gear, and the restriction on rotation of the parking gear is released. When the rotation of the parking gear is no longer restricted, the rotation of the drive shaft is no longer restricted so that the drive wheels can rotate, and a transition to a range other than the parking range is performed.

In the range selection mechanism, a detent spring, which is formed into a plate shape and can be elastically deformed with one end fixed, is provided at a position away from the manual plate, and a recess formed in the manual plate by the elastic force of the detent spring. It is known that the rotation of the manual plate is restricted and the range is maintained by being pressed down (for example, see Patent Document 1).

Japanese Patent Application Publication No. 2015-209877

However, in the above-mentioned parking mechanism, it is necessary to secure a large space in the transmission case for arranging the leaf spring-like detent spring, and other parts of the range selection mechanism and the detent spring must be arranged inside the transmission case. There may be restrictions on the shape and size of each component. Furthermore, by designing the position of the manual shaft in consideration of the position of the detent spring, the degree of freedom in layout design may be reduced.

Therefore, an object of the present invention is to improve the degree of freedom in designing the shape, size, and layout of parts within a transmission case.

A range selection mechanism according to the present invention includes: a manual shaft that rotates in response to a range selection operation; a range selection lever that is coupled to the manual shaft in a transmission case and rotates with the manual shaft; and a transmission case. a holding plate having a plurality of range holding parts, which is arranged in a fixed state, and is located between the range selection lever and the holding plate and moves with respect to the holding plate as the range selection lever rotates; a held object held by one of the range holding parts of the plurality of range holding parts; a connection plate connected to the manual shaft in the transmission case and rotated with the manual shaft; and the connection plate. The parking rod includes a parking rod connected to the plate and moved as the connecting plate rotates, and an elastic member biasing the held object in a direction to press the holding plate.

Thereby, the object to be held is held in a state where it is pressed against the holding plate by the elastic member.

Second, in the range selection mechanism according to the present invention described above, it is desirable that a coil spring inserted through the manual shaft be used as the elastic member.

As a result, the body to be held is urged by the coil spring in a direction in which it is pressed against the holding plate.

Thirdly, in the range selection mechanism according to the present invention described above, it is preferable that the range selection lever is elastically deformable in a direction toward and away from the holding plate, and that the range selection lever is used as the elastic member.

As a result, the range selection lever biases the held object in a direction in which it is pressed against the holding plate.

Fourthly, in the range selection mechanism according to the present invention described above, it is desirable that the connection plate and the range selection lever are integrally formed.

This eliminates the need for a member for connecting the manual shaft and the parking pole and a member for moving the held object.

Fifth, in the range selection mechanism according to the present invention described above, holding holes are formed as the plurality of range holding parts, and the plurality of holding holes are formed to be spaced apart in the rotating direction of the range selection lever. This is desirable.

Thereby, the object to be held is held in a state inserted into the holding hole.

Sixthly, in the above-mentioned range selection mechanism according to the present invention, it is desirable that at least two of the plurality of holding holes are formed to have different sizes.

As a result, the amount of insertion into the holding hole of the held object changes depending on the size of the holding hole, so the amount of movement when the held object comes out of the holding hole differs, which is necessary to rotate the range selection lever. The power considered to be different is different.

Seventhly, in the range selection mechanism according to the present invention described above, a plurality of connecting holes are formed in the holding plate, and the plurality of holding holes and the plurality of connecting holes are arranged in an alternating and continuous state. is desirable.

As a result, at least a portion of the held object is inserted into the holding hole or the connecting hole during movement.

Eighthly, in the range selection mechanism according to the present invention described above, the holding plate has a plate-shaped base portion and a plurality of protrusions protruding from the base portion toward the range selection lever side, and It is preferable that the protrusions are provided apart from each other in the rotating direction of the range selection lever, and that the range holding part is located between the two protrusions.

As a result, the object to be held is held in the portion between the two protrusions on the base portion.

Ninthly, in the range selection mechanism according to the present invention described above, it is desirable that at least two of the plurality of protrusions protrude from the base portion by different amounts.

As a result, the amount of movement when the held object is moved relative to the holding plate and overcomes the protrusion differs, and the force required to rotate the range selection lever differs.

According to the present invention, the range is held by holding the object to be held pressed against the holding plate by the elastic member, so there is no need to provide a detent spring that is shaped like a leaf spring and requires a large installation space. This reduces restrictions on the shape and size of parts within the transmission case, increasing the degree of freedom in layout design.

However, the front, back, top, bottom, left and right directions shown below are for convenience of explanation, and the implementation of the present invention is not limited to these directions.

<Configuration of the first embodiment>
First, the configuration of the range selection mechanism 1 according to the first embodiment will be described (see FIGS. 1 to 8). The range selection mechanism 1 is provided in a power transmission device equipped with an automatic transmission mechanism in a vehicle.

In a vehicle, the driver operates the shift lever to select ranges such as parking range (P range), reverse range (R range), neutral range (N range), and drive range (D range). It will be done. Furthermore, some vehicles select a parking range by operating a parking switch.

The parking range is a range for keeping the vehicle stopped, the reverse range is for moving the vehicle backwards, and the neutral range is a range for cutting off power transmission from the engine or other power source to the drive shaft. The drive range is a range for driving the vehicle forward. The parking range and neutral range correspond to non-driving ranges, and the reverse range and drive range correspond to driving ranges.

In the shift lever, shift positions for selecting a parking range, a reverse range, a neutral range, and a drive range are determined, and the selection of the parking range is performed by operating the shift lever to the parking shift position. Furthermore, the parking range may be selected by operating a parking switch.

The range selection mechanism 1 includes a manual shaft 2 inserted into a transmission case 100, a connection plate 3 connected to the manual shaft 2 inside the transmission case 100, a range selection lever 4 connected to the manual shaft 2, and a range selection mechanism 1. A held object 5 that moves integrally with the selection lever 4, a parking pole 6 connected to the connecting plate 3, a holding plate 7 fixed to the transmission case 100, and a coil spring 8 into which the manual shaft 2 is inserted. (See Figure 1).

The manual shaft 2 is positioned so as to extend in the front-rear direction, and is inserted into the transmission case 100 so as to pass through a control unit 101 provided on the outer surface of the transmission case 100.

The outer end 2a of the manual shaft 2 is connected to a shift lever (not shown) via a connecting member such as a cable (not shown), and is rotated around an axis in response to operation of the shift lever.

A connecting plate 3 and a range selection lever 4 are coupled to a portion of the manual shaft 2 near an inner end 2b located inside the transmission case 100 so as to be spaced apart from each other in the longitudinal direction.

The connection plate 3 is formed into a vertically long plate shape facing in the front-rear direction, and one end in the longitudinal direction is coupled to the manual shaft 2. A parking rod 6 is rotatably connected to the other end of the connecting plate 3 in the longitudinal direction. The connecting plate 3 is rotated as the manual shaft 2 is rotated.

The range selection lever 4 is formed in the shape of a vertically long plate facing in the front-rear direction, and one end in the longitudinal direction is coupled to the manual shaft 2. An insertion hole 4a is formed at the other end of the range selection lever 4 in the longitudinal direction. The range selection lever 4 is rotated as the manual shaft 2 is rotated.

The held object 5 is, for example, formed in a spherical shape and has a diameter larger than the diameter of the insertion hole 4a, and is partially inserted into the insertion hole 4a while being positioned between the range selection lever 4 and the holding plate 7. . Note that the held body 5 may be formed integrally with the range selection lever 4, and in this case, it may be formed in a hemispherical shape, for example.

The held body 5 is moved in the direction of rotation of the range selection lever 4 as the range selection lever 4 rotates.

The parking rod 6 has a connecting shaft portion 6a connected to the connecting plate 3 and an operating shaft portion 6b bent in a direction perpendicular to the connecting shaft portion 6a, and is displaced as the connecting plate 3 rotates. be done.

A parking pole (not shown) is engaged with the end of the operating shaft portion 6b opposite to the connecting shaft portion 6a. The parking pole has a meshing portion, and is rotated in accordance with the movement position of the parking rod 6 to be meshed with or disengaged from a parking gear (not shown). A drive shaft (not shown) is connected to the parking gear, and when the parking pole is engaged with the parking gear, the transition is made to the parking range, and when the parking pole is disengaged from the parking gear, the shift is made to the parking range. A transition to the range is made.

The holding plate 7 is formed in a vertically long plate shape facing in the front-rear direction, and is fixed to the inner surface of the transmission case 100, for example. The holding plate 7 functions as a range holding part in which the object to be held 5 is held, and has holding holes 9, 9, . . . penetrated in the front-back direction. The holding holes 9, 9, . . . are formed in the same number as the selectable ranges.

The diameter of the holding holes 9, 9, . . . is smaller than the diameter of the object to be held 5. The holding holes 9, 9, . . . are formed to be spaced apart in the rotating direction of the range selection lever 4, and the holding holes 9P, 9R, 9N, corresponding to the parking range, reverse range, neutral range, and drive range, respectively. 9D are arranged in sequence.

The holding holes 9, 9, . . . have different sizes, and the holding hole 9P is the largest. However, the sizes of at least two of the holding holes 9, 9, . . . may be different, and in particular, the holding hole 9P may be larger than the other holding holes 9, 9, 9. You can leave it there.

Furthermore, connection holes 10, 10, 10 are formed in the holding plate 7, passing through them in the front-rear direction. The connecting holes 10, 10, 10 are all smaller than the holding hole 9.

The holding holes 9, 9, . . . and the connecting holes 10, 10, 10 are arranged in an alternating and continuous state, and the connecting hole 10A is located between the holding holes 9P and 9R.

A coil spring 8 that functions as an elastic member is supported on the manual shaft 2. As the coil spring 8, for example, a compression coil spring is used. A portion of the manual shaft 2 that protrudes outward from the control unit 101 is inserted into the coil spring 8 .

A support plate 11 is coupled to the outer end 2a of the manual shaft 2. The coil spring 8 is compressed and positioned between the support plate 11 and the control unit 101 with the manual shaft 2 inserted therethrough, and urges the manual shaft 2 in the direction from the inner end 2b to the outer end 2a. are doing.

As the manual shaft 2 is biased by the coil spring 8 , the range selection lever 4 is biased in a direction toward the holding plate 7 , and the object to be held 5 is pressed against the holding plate 7 by the range selection lever 4 . Therefore, the object to be held 5 is held with a portion thereof inserted into the holding hole 9 , and is pressed against the range selection lever 4 by the biasing force of the coil spring 8 and pressed against the opening edge of the holding hole 9 .

<Range switching operation in the first embodiment>
Next, the range switching operation in the range selection mechanism 1 according to the first embodiment will be explained using an example in which the parking range is switched to the reverse range (see FIGS. 2 to 4).

In the state where the parking range is selected, the object to be held 5 is pressed against the opening edge of the holding hole 9P by the biasing force of the coil spring 8, and is held in a state where a portion is inserted into the holding hole 9P (Fig. 2 reference). At this time, the other part of the held body 5 is inserted into the insertion hole 4a of the range selection lever 4, and is prevented from falling off from the range selection lever 4.

When the range selection lever 4 is rotated, the moving force associated with the range selection lever 4 is applied to the held object 5, so a force acts in the direction opposite to the biasing force of the coil spring 8, and the held object 5 is moved. It comes off from the holding hole 9P and rides on the connecting hole 10A, resulting in a non-retained state (see FIG. 3). At this time, the coil spring 8 is brought into the most compressed state, and the held body 5 is pressed against the opening edge of the connecting hole 10A by the biasing force of the coil spring 8.

When the range selection lever 4 is further rotated and the held object 5 is moved to the holding hole 9R corresponding to the reverse range, the held object 5 is pressed against the opening edge of the holding hole 9R by the biasing force of the coil spring 8 and held. It is held with a portion inserted into the hole 9R (see FIG. 4). In this way, switching from the parking range to the reverse range is performed.

In the range switching operation, the held object 5 is moved with at least a portion thereof inserted into the holding hole 9 or the connecting hole 10. Therefore, falling off of the held object 5 from the holding plate 7 is prevented. Note that protrusions for preventing the held object 5 from falling off from the holding plate 7 may be provided at both ends of the holding plate 7 in the rotating direction of the range selection lever 4.

Further, since the held body 5 is formed in a spherical shape and is provided separately from the range selection lever 4, when the held body 5 is moved between the holding holes 9, 9, . . . The holding body 5 can be moved smoothly and the range can be changed smoothly. Further, the body 5 to be held is also rotatable relative to the holding plate 7, so that movement of the body 5 to be held between the holding holes 9, 9, . . . and switching of ranges can be smoothly performed.

Furthermore, since the holding holes 9, 9, . . . are formed to have different sizes, the amount of insertion of the held object 5 into the holding holes 9, 9, . The amount of movement in the front-rear direction when passing over the connecting hole 10 is different (see FIG. 5). As a result, the force required to rotate the range selection lever 4 differs depending on the range to be changed.

Therefore, the force required to operate the shift lever differs depending on the range to be switched, and the range switching feels different depending on the switching position, making it easier to recognize the shift position.

As described above, in the range selection mechanism 1, the held body 5 is held pressed against the holding plate 7 by the elastic force of the coil spring 8 instead of the detent spring, and the range is held.

Therefore, there is no need to provide a detent spring that is shaped like a leaf spring and requires a large installation space, and restrictions on the shape and size of components within the transmission case 100 are reduced, making it possible to increase the degree of freedom in layout design.

Further, by forming the holding hole 9 as the microwave holding portion, the object to be held 5 is held in a state inserted into the holding hole 9, so that the object to be held 5 can be held with a simple configuration.

Although the case where the holding hole 9 was formed in the holding plate 7 as a microwave holding part was shown above, the holding plate 7A may be used instead of the holding plate 7 (see FIGS. 6 and 7).

The holding plate 7A has a plate-shaped base portion 7a and protrusions 12, 12, . . . that protrude from the base portion 7a. The protrusions 12, 12, . . . project toward the range selection lever 4 while being spaced apart from each other in the rotating direction of the range selection lever 4. The protrusions 12, 12, . . . have different amounts of protrusion from the base portion 7a, for example. However, the amount of protrusion of at least two of the protrusions 12, 12, . . . from the base portion 7a may be different.

In the holding plate 7A, the protrusions 12, 12, . . . function as reinforcing ribs, so that sufficient strength of the holding plate 7A is ensured.

A portion of the base portion 7a between the two protrusions 12, 12 is formed as a holding surface 13 that functions as a microwave holding portion. Among the holding surfaces 13, 13, . . ., holding surfaces 13P, 13R, 13N, and 13D corresponding to a parking range, a reverse range, a neutral range, and a drive range, respectively, are arranged side by side in this order. A protrusion 12A is located between the holding surface 13P and the holding surface 13R. For example, the protrusion 12A has the largest protrusion amount from the base portion 7a.

In a range switching operation when the holding plate 7A is used, for example, from a parking range to a reverse range, when the parking range is selected, the held object 5 is pressed from both sides by the protrusions 12 and 12A, It is held in a state where it is pressed against the holding surface 13P by the biasing force of the coil spring 8 (see FIG. 7).

When the range selection lever 4 is rotated, a force acts on the held object 5 in a direction opposite to the biasing force of the coil spring 8, and the held object 5 is placed in a non-held state in which it rides on the protrusion 12A. At this time, the coil spring 8 is in the most compressed state.

When the range selection lever 4 is further rotated, the held object 5 climbs over the protrusion 12A and is pressed against the holding surface 13R by the biasing force of the coil spring 8 while being pressed by the protrusions 12A and 12 from both sides. Retained. In this way, switching from the parking range to the reverse range is performed.

Further, since the held body 5 is formed in a spherical shape and is provided separately from the range selection lever 4, the held body 5 is rotatable with respect to the range selection lever 4 and the holding plate 7A, and the held body 5 is rotatable with respect to the range selection lever 4 and the holding plate 7A. It is possible to smoothly move over the protrusions 12, 12, . . . and switch ranges.

Furthermore, since the projections 12, 12, . The force required to rotate the range selection lever 4 differs depending on the range.

Therefore, the force required to operate the shift lever differs depending on the range to be changed, making it easier to sense range switching and recognizing the shift position.

Furthermore, in the range selection mechanism 1 configured as described above, an example has been shown in which the connection plate 3 and the range selection lever 4 are configured as separate members, but the connection plate 3 and the range selection lever 4 are integrated. Alternatively, the range switching lever 14 may be formed as a fixed range switching lever 14 (see FIG. 8).

The range switching lever 14 is formed in the shape of a vertically elongated plate facing in the front-rear direction, and its center portion in the longitudinal direction is coupled to the inner end portion 2b of the manual shaft 2, and the parking rod 6 is rotatable at one end portion in the longitudinal direction. The held body 5 is inserted into the insertion hole 14a formed at the other end in the longitudinal direction. As a result, a member for connecting the manual shaft 2 and the parking pole 6 and a member for moving the held object 5 are not required, so that the number of parts can be reduced.

<Second embodiment>
Next, a range selection mechanism 1A according to a second embodiment will be described (see FIGS. 9 and 11).

Note that the range selection mechanism 1A shown below differs from the range selection mechanism 1 described above in that only the held body 5 is biased by a range selection lever 4A that is elastically deformable instead of the coil spring 8. differ. Therefore, only the parts that are different from the range selection mechanism 1 will be explained in detail, and the other parts will be given the same reference numerals as the same parts in the range selection mechanism 1, and the explanation will be omitted.

The range selection lever 4A is formed in a vertically elongated plate shape facing in the front-rear direction, and one end in the longitudinal direction is coupled to the manual shaft 2 in a state where it can be elastically deformed in a direction toward and away from the holding plate 7, and functions as an elastic member. (See Figure 9). The range selection lever 4A is rotated as the manual shaft 2 is rotated.

An insertion hole 4a is formed at the other end in the longitudinal direction of the range selection lever 4A, and a part of the object 5 to be held is inserted into the insertion hole 4a.

The held body 5 is moved in the rotational direction of the range selection lever 4A as the range selection lever 4A rotates, and is urged in the direction of being pressed against the holding plate 7 by the elasticity of the range selection lever 4A. .

In the range selection mechanism 1A described above, a portion of the held object 5 is inserted into the holding hole 9, and is held in a state where it is pressed against the opening edge of the holding hole 9 by the biasing force of the range selection lever 4A.

Next, the range switching operation in the range selection mechanism 1A according to the second embodiment will be described using an example in which the range is switched from the parking range to the reverse range.

In the state where the parking range is selected, the object to be held 5 is pressed against the opening edge of the holding hole 9P and held by the elastic biasing force of the range selection lever 4A, with a portion inserted into the holding hole 9P. (See Figure 10)

When the range selection lever 4A was rotated, a force was applied to the held object 5 in a direction opposite to the biasing force of the range selection lever 4A, and the held object 5 came off from the holding hole 9P and rode on the connecting hole 10A. is placed in a non-retained state. At this time, the range selection lever 4A is deformed the most, and the held body 5 is pressed against the opening edge of the connecting hole 10A by the biasing force of the range selection lever 4A.

When the range selection lever 4A is further rotated and the held object 5 is moved to the holding hole 9R corresponding to the reverse range, the held object 5 is inserted into the holding hole 9R and is pushed into the holding hole by the biasing force of the range selection lever 4A. It is held pressed against the opening edge of 9R. In this way, switching to the reverse range is performed.

As described above, in the range selection mechanism 1A, the range is held by the elastic force of the range selection lever 4A instead of the detent spring.

Therefore, a stable range switching operation is performed without the manual shaft 2 being moved in the axial direction, and there is no need to provide a detent spring that is shaped like a leaf spring and requires a large installation space, and the parts inside the transmission case can be easily moved. Restrictions on shape and size are reduced, and the degree of freedom in layout design can be increased.

Note that in the range selection mechanism 1A, a holding plate 7A may be used instead of the holding plate 7.

Moreover, the range selection mechanism 1A may also be formed as a range switching lever 14A in which the connection plate 3 and the range selection lever 4A are integrated (see FIG. 11). In the range switching lever 14A, the part to which the parking rod 6 is connected is provided as a connecting part 15 with the manual shaft 2 as a reference, and the part into which the held object 5 is inserted is elastically deformable in the direction of coming into contact with and separating from the holding plate 7. The range selection unit 16 is provided as a range selection unit 16. In the range switching lever 14A, the range selection section 16 functions as an elastic member. As a result, a member for connecting the manual shaft 2 and the parking pole 6 and a member for moving the held object 5 are not required, so that the number of parts can be reduced.
