Abstract

PROBLEM TO BE SOLVED: To provide an automatic gear change operation device of an automobile which can prevent the generation of noise based on the movement of a shift lock cam to a rotating shaft direction.SOLUTION: A floating formation member 107a5 of an automatic gear change operation device is formed so that a radius R107 from a reference face S107 up to an end part of the floating formation member 107a5 becomes longer than a length L107 along a shift lock cam rotating shaft J107 from a cross point C107 between the reference face S107 including a rotating shaft J107a5 by itself, and vertical to the shift lock cam rotating shaft J107, and the shift lock cam rotating shaft J107 up to a surface P107 of a shift lock cam 107a at an end face P105 side. By this constitution, the shift lock cam 107a can be brought into a floating state that the shift lock cam 107a is floated from the end face P105 of a box body 105. Accordingly, since the shift lock cam 107a and the end face P105 are prevented from contacting with each other, the generation of noise based on the contact of them can be prevented.SELECTED DRAWING: Figure 4

Description

  The present invention relates to an automatic transmission operating device for an automobile, and more particularly to an apparatus for preventing the generation of abnormal noise.

  A conventional automatic gear shifting operation device for an automobile will be described with reference to an automatic gear shifting operation device shown in FIGS. As shown in FIG. 6, in the automatic transmission operating device having the shift lock mechanism, the shift lock mechanism includes a solenoid 15, a lock means 18, and an operation member 16, and the operation member 16 includes at least two arm portions. (16a, 16b), one arm portion thereof being connected to the operation portion of the solenoid 15, and the other arm portion being connected to the lock means 18, and a buffer member 16ca at the tip of one arm portion. As shown in FIG. 7, a wall surface 4d is formed on the outer surface of the bracket 4 so as to come into contact with the buffer member 16ca at the rotation end of one arm portion, and the buffer member 16ca is directed in the radial direction. It has a convex acute angle portion P, and the acute angle portion P abuts against the wall surface 4d at the rotation end of one arm portion.

  Thus, by limiting the rotation range of the tip of the third arm portion 16c to the range in the wall surface 4d, the rotation range of the operation member can be restricted, and the buffer member 16ca is directed in the radial direction. Since it has a shape having a convex acute angle portion P, the contact with the wall surface 4d is performed at one point or an area close thereto, and an impact sound (that is, operation sound) at the time of contact can be suppressed.

  Further, as shown in FIG. 8, the buffer member 16ca is in a state in which the acute angle portion P is always in contact with the bottom surface 4da surrounded by the wall surface 4d, and on the bottom surface 4da when the operation member 16 is rotated. It is set to slide or roll. As described above, since the apex of the acute angle portion P is configured to slide or roll in contact with the bottom surface 4da, an operation sound generated from the buffer member 16ca can be suppressed (see Patent Document 1 above). .

JP 2008-120387A

  The above-described conventional automatic shift operation device has the following points to be improved. In the conventional automatic speed change operation device, the impact sound (that is, the operation sound) at the time of contact with the wall surface 4d in the rotation direction of the operation member 16 is suppressed, while it is caused by the play of the engagement between the operation member 16 and the shaft portion 4a. There is a point that should be improved that the contact sound between the operation member 16 and the bottom surface 4da that is generated along with the rotation of the operation member 16 cannot be suppressed.

  SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide an automatic transmission operation device for an automobile that can prevent the generation of abnormal noise due to the movement of a shift lock cam in the direction of the rotation axis.

  Means for solving the problems in the present invention and the effects of the invention will be described below.

It is a figure which shows the conventional automatic transmission operation apparatus of the motor vehicle.

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

  An automatic transmission operation device 100 for an automobile (hereinafter referred to as an automatic transmission operation device 100), which is an embodiment of an automatic transmission operation device for an automobile according to the present invention, will be described below. The automatic speed change operation device 100 is a device that enables a driver to perform a speed change operation of an automatic transmission (automatic transmission), and is disposed on a floor in a vehicle interior or an instrument panel in front of the vehicle interior.

  A perspective external view of the automatic transmission operation device 100 is shown in FIG. The automatic transmission operation device 100 includes a shift lever 101, an automatic transmission operation mechanism 103, a housing 105, and a shift lock mechanism 107.

  FIG. 2 shows a state in which the automatic transmission operating device 100 shown in FIG. 1 is viewed from the right side. In FIG. 2, only the configuration related to the shift lock mechanism 107 is shown in a simplified manner in order to explain the shift lock mechanism 107. The shift lever 101 rotates in a predetermined direction around a predetermined rotation axis J101 (hereinafter, shift lever rotation axis J101). The automatic shift operation mechanism 103 is operated by the rotation of the shift lever 101, and a shift process for causing the automatic transmission to perform a shift operation is executed. The shift lever 101 includes a shift lock pin 101a, a shift lock release button 101b, a grip portion 101c, and a shaft portion 101d. The shift lock pin 101a is formed on the shaft portion 101d. The shift lock pin 101a moves in conjunction with the movement of the entire shift lever 101. The shift lock release button 101b is disposed at the tip of the grip portion 101c. The shift lock release button 101b allows the entire shift lever 101 to move in the direction of the shift lever rotation axis J101 when the driver pushes it in a predetermined direction. When the shift lever 101 is in the parking position, when the brake pedal (not shown) is depressed and the shift lock release button 101b is pushed in a predetermined direction, the shift lock mechanism 107 (described later) is released. . When the shift lock mechanism 107 is released, the entire shift lever 101 can be moved to push in the direction of the shift lever rotation axis J101 and then rotated to move to the reverse position, neutral position, and drive position. This prevents inadvertent shift changes.

  Returning to FIG. 1, the automatic shift operation mechanism 103 executes a shift process for causing the automatic transmission to perform a shift operation based on the rotation of the shift lever 101. Since the automatic transmission operation mechanism 103 is the same as that of the prior art, detailed description is omitted.

  The housing 105 has an automatic transmission operation mechanism 103 inside. The housing 105 has an end face P105 that is parallel to the rotation direction of the shift lever 101 and perpendicular to the shift lever rotation axis J101. FIG. 3 shows a state where the shift lock mechanism 107 is removed from the state of FIG. In FIG. 3, the shift lock mechanism 107 is indicated by a dotted line. A lock pin guide opening 105a, a shift lock cam rotation shaft receiving hole 105b, and a shift lock cam regulating wall 105c are formed on the end surface P105 of the housing 105.

  The lock pin guide opening 105a is an opening that regulates the movement path of the shift lock pin 101a. The lock pin guide opening 105a has a pushing direction restricting portion 105a1 and a turning direction restricting portion 105a3 for restricting a path along which the shift lock pin 101a moves. When the shift lever 101 is in the parking position, movement in the rotation direction is restricted by the push-in direction restricting portion 105a1, and movement only in the push-in direction is possible. When the shift lever 101 is pushed in, the shift lock pin 101a moves in the direction of the shift lever rotation axis J101 along the push-in direction restricting portion 105a1, and the shift lock pin 101a moves from the push-in direction restricting portion 105a1 at the maximum push-in. The shift lever 101 can be moved in the rotation direction.

  The shift lock cam rotation shaft receiving hole 105b receives the rotation shaft portion 107a9 of the shift lock cam 107a, and holds the shift lock cam 107a so as to be rotatable about the rotation shaft J107 (hereinafter referred to as shift lock cam rotation shaft J107). . The shift lock cam restricting wall 105c is a flat plate-like protruding member that restricts the rotation range of the shift lock cam 107a.

  Returning to FIG. 2, the shift lock mechanism 107 has a shift lock cam 107a and a solenoid 107b. The shift lock cam 107a has a lock pin engaging arm portion 107a1, a floating arm portion 107a3, a floating forming member 107a5, a solenoid connecting projection 107a7, and a rotating shaft portion 107a9. When the shift lever 101 is in the parking position, the shift lock cam 107a moves the shift lock pin 101a by positioning the lock pin engaging arm portion 107a1 in the direction of the shift lever rotation axis J101 with respect to the shift lock pin 101a. To prevent the shift lever 101 from moving in the direction of the shift lever rotation axis J101.

  The lock pin locking arm portion 107a1 has a tip portion that comes into contact with the shift lock pin 101a when the shift lever 101 is in the parking position. The floating arm portion 107a3 is disposed at a predetermined angle with respect to the lock pin engaging arm portion 107a1 around the rotation shaft portion 107a9. The floating forming member 107a5 is disposed so as to be fitted to the floating arm 107a3. The floating forming member 107a5 is formed of an elastic material, for example, a resin member, and has a abacus frame shape.

  The solenoid connection protrusion 107a7 is connected to the solenoid 107b. The solenoid connection protrusion 107a7 transmits the movement of the solenoid 107b to the shift lock cam 107a, and rotates the shift lock cam 107a in a predetermined direction around the shift lock cam rotation axis J107. The rotation shaft portion 107 a 9 is fitted into the shift lock cam rotation shaft receiving hole 105 b of the housing 105. As a result, the shift lock cam 107a can rotate in a predetermined direction around the shift lock cam rotation axis J107.

  The XX cross section of FIG. 2 is shown in FIG. In the shift lock cam 107a, the floating forming member 107a5 is fitted to the floating arm 107a3. The floating forming member 107a5 is locked to the floating arm 107a3 by its own elastic force, and rotates around the floating arm 107a3 by the rotation of the floating arm 107a3. That is, the floating forming member 107a5 can roll in accordance with the rotation of the shift lock cam 107a.

  The floating forming member 107a5 includes its own rotation axis J107a5 and includes a reference plane S107 perpendicular to the shift lock cam rotation axis J107 and the intersection C107 between the shift lock cam rotation axis J107 and the surface P107 on the end face P105 side of the shift lock cam 107a. The radius R107 from the reference surface S107 to the end of the floating forming member 107a5 is longer than the length L107 along the shift lock cam rotation axis J107. Thereby, the shift lock cam 107a can be set in a floating state in which the shift lock cam 107a is levitated from the end surface P105 of the housing 105. Therefore, since it can prevent contacting between the shift lock cam 107a and the end surface P105, generation | occurrence | production of the noise based on both contact can be prevented.

  Further, since the floating forming member 107a5 is formed of an elastic material, the shift can be absorbed even if the shift lock cam 107a is installed on the end face P105 side with respect to the planned position. That is, when the shift lock cam 107a is arranged, it is not necessary to accurately set the positional relationship with other components such as the solenoid 107b, and thus the manufacturing is easy.

  Furthermore, even when abnormal noise occurs due to aging, only the floating forming member 107a5 needs to be replaced, so that maintenance work is facilitated and maintenance costs can be reduced.

  The solenoid 107b has an operation part 107b1 that can be expanded and contracted. The operating portion 107b1 has a connection hole 107b3 that engages with the solenoid connection protrusion 107a7 of the shift lock cam 107a. As the solenoid 107b expands and contracts the operating portion 107b1, the shift lock cam 107a is rotated in a predetermined direction via the connection hole 107b3 and the solenoid connection protrusion 107a7.

  The operation of the shift lock cam 107a accompanying the movement of the solenoid 107b will be described with reference to FIG. FIG. 5 shows a state where the shift lock cam 107a shown in FIG. 2 is rotated by a predetermined angle and the shift lock mechanism 107 is released. When the shift lever 101 is in the parking position and the brake pedal is depressed, the solenoid 107b moves the operating portion 107b1 in the direction of the arrow a1. As the operating portion 107b1 moves, the shift lock cam 107a rotates in the direction of the arrow a3, and the engagement between the shift lock pin 101a and the lock pin engaging arm portion 107a1 is released. As a result, the shift lever 101 can be pushed in the direction of the shift lever rotation axis J101. When the shift lock release button 101b is pushed in a predetermined direction and the shift lever 101 is turned, the shift lock pin 101a is moved along the push direction restricting portion 105a1 and the turn direction restricting portion 105a3 of the lock pin guide opening 105a. Move in the a5 direction.

If it rotates with the shift lock cam 107a which was rotating centering on 107a3, it will not be limited to an illustration. For example, you may make it fix to the floating arm part 107a3. In this case, the floating forming member 107a5 slides as the shift lock cam 107a rotates.

  In the first embodiment, the floating forming member 107a5 has an abacus frame shape. However, the floating forming member 107a5 is not limited to the illustrated example as long as it can move smoothly. For example, the end surface may be an annular shape with a curved surface.

  Further, in the first embodiment, the floating forming member 107a5 is disposed on the floating arm 107a3. However, the floating forming member 107a5 is not limited to the illustrated example as long as the shift lock cam 107a can be disposed in a floating state. For example, you may make it arrange | position to the lock pin latching arm part 107a1.

  The automatic transmission operation device for automobiles according to the present invention can be used as an automatic transmission operation device for passenger cars, for example.
