Abstract

PURPOSE:To improve the concentricity by providing a damper force giving member to a shift rod integrally, connecting them to a damper piston, and making to give the damper force when the shift rod moves a specific amount from a neutral position, in a transmission operating device provided with a damper mechanism. CONSTITUTION:When a transmission is moved from a neutral position to a shift position, first a gear shift lever 4 is moved to a desired select position along the axis of a shift rod 2 by a select lever 5. As a result, the shift rod 2 rotates a specific amount through an output lever 10 and a rotary lever 6. Consequently, a damper force giving member 21 also rotates in the same direction, and a damper mechanism 22 moves a damper piston 27 laterally. As a result, a pressure fluid in a damper chamber 28 or 29 flows to a pressure fluid chamber 26 through an orifice 30 or 31, and a damper operation is carried out. This damper force functions as reaction force reversely in the shift direction of the gear shift lever 4, and the sift operation force is eliminated after synchronization is finished, so as to prevent gear collision.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a transmission operating device, and more particularly to a transmission operating device provided with a damper mechanism that directly or indirectly applies a damper force to a shift rod equipped with a shift actuator. It is something.

0002

[Prior Art] Conventional transmission operating devices that use fluid pressure (particularly pneumatic pressure) require a large shift operation force when shifting into gear, so even after synchronization is complete, the shift operation continues with this large shift operation force. Doing so would result in a gear collision, resulting in damage to the transmission and operating equipment due to the impact force. Therefore, a solution has been proposed in which an oil damper mechanism is provided in a transmission operating device, and the above-mentioned disadvantages are solved by the damping action of this oil damper mechanism.

0003

However, in the conventional transmission operating device described above, since the oil damper mechanism is located on the axis of the shift rod and is directly attached to the shift rod, the influence of coaxiality It was easier to receive. If the coaxiality is poor, the damper piston will interfere with the damper cylinder, and phenomena such as the damper piston becoming stuck due to wear of the damper cylinder and the damper piston, or oil leaking from the damper cylinder will occur. As a result, the damping action of the oil damper mechanism is not performed effectively, resulting in an impact force, or the oil damper mechanism prevents the normal operation of the transmission operating device. That is, the oil damper mechanism must be reliably disposed on the axis of the shift rod, and care must be taken during assembly, resulting in a drawback that the efficiency of assembly cannot be improved. Furthermore, since the oil damper mechanism regulates the operating speed of the device body, it has the disadvantage that the shift time becomes long.

The present invention was made in view of the above circumstances, and its purpose is to eliminate the problem of poor coaxiality between the shift rod, etc. and the damper mechanism, and to increase the degree of freedom in the layout of the damper mechanism. However, it is an object of the present invention to provide a transmission operating device that can shorten the shift time.

A tip of the damper force applying member and the damper piston are connected to each other, and after the shift rod has moved a predetermined amount from a neutral position, a damper force from the damper mechanism is applied to the shift rod via the damper force applying member. It is configured to do so.

Another aspect of the present invention provides a transmission operation comprising a shift rod driven by a shift actuator and a damper mechanism that performs a damping action after the shift rod moves a predetermined amount from a neutral position. In the apparatus, a damper force applying member is integrally provided on the output rod of the shift actuator, the damper mechanism is provided in association with the damper force applying member, and a damper piston is disposed within the housing of the damper mechanism. , communicating damper chambers formed on both sides of the damper piston with a pressure fluid chamber via an orifice, and connecting the tip of the damper force applying member and the damper piston to each other;

[0008]

[Function] In the transmission operating device of the present invention, the damper mechanism is provided separately from the shift rod, and after the shift rod has moved a predetermined amount from the neutral position, the damper force from the damper mechanism is applied to the damper applying member or the piston rod. Because it is applied directly or indirectly to the shift rod via the damper mechanism, there is no possibility of poor coaxiality between the shift rod, etc. and the damper mechanism, and it is possible to eliminate various problems caused by poor coaxiality. , the layout of the damper mechanism can be freely arranged, and the shift time can be shortened.

This operating device has a cylinder housing 1 for shift operation that is attached to the upper surface of a housing of a transmission (not shown), and within the cylinder housing 1 is a shift rod 2 that rotates around its axis. movably supported. A spline is formed in the intermediate portion of the shift rod 2, and a gear shift lever 4 is movably attached to the spline portion 3. Thus, the gear shift lever 4 is configured to be moved along the axial direction of the shift rod 2 via the select lever 5 by a select operation of a select rod (not shown), and to perform a shift operation at a desired select position. .

Further, the upper end of a rotating lever 6 is integrally attached to one end of the shift rod 2, and is connected via this rotating lever 6 to a shift actuator 7 that rotationally drives the shift rod 2. has been done. This actuator 7 has a cylinder housing 8 that is disposed in a direction perpendicular to the shift rod 2 and is fixed to one open end 1a of a cylinder housing 1 for shift operation.

An output rod 9 is supported within the cylinder housing 8 so as to be slidable along its axial direction. An output lever 10 connected to the lower end of the rotary lever 6 is fixed on the outer periphery of the intermediate portion of the output rod 9. When the output lever 10 moves together with the sliding of the output rod 9, the shift rod 2 is adapted to rotate via a rotation lever 6. Further, inside the cylinder housing 8, there is a fixed piston 12 positioned and fixed on the outer periphery of one end of the output rod 9 with a snap ring 11, and a fixed piston 12 located in front of the output rod 9 with a seal member 8a placed between them. A free piston 13 is provided facing the fixed piston 12 and the free piston 13.
Three pressure chambers 14, 15, and 16 are defined by.

Each of the pressure chambers 14, 15, 16 of the shift actuator 7 is connected to an air tank through an electromagnetic switching valve (not shown), and by selectively opening and closing the electromagnetic switching valve, for example, When compressed air is supplied only to the pressure chamber 14, the output rod 9 moves to the left in FIG. Furthermore, when compressed air is supplied only to the pressure chamber 15, the output rod 9 moves to the right in FIG. Furthermore, when compressed air is supplied to the pressure chambers 14 and 16, the output rod 9 is fixed at the neutral position without moving in the left-right direction. That is, since the shift rod 2 is rotationally driven to three shift positions by the actuator 7, the operating device is configured so that a desired gear shift of the transmission can be obtained by selecting one of these three shift positions. has been done. Note that a stroke sensor 17 for detecting the stroke position of the output rod 9 is disposed on the other end side of the output rod 9.

On the other hand, a casing 19 rotatably supports the other end of the shift rod 2 protruding from the cylinder housing 1 through a sleeve 18, at the other open end 1b of the cylinder housing 1 for shift operation. An opening 20 is formed in the lower surface of the casing 19. A damper force applying member 21 that applies a damper force of a damper mechanism to be described later to the shift rod 2 is integrally provided at the other end of the shift rod 2 via a sleeve 18. This damper force imparting member 21 is disposed perpendicular to the shift rod 2, and the base end 21a is formed into a cylindrical shape to fit into the sleeve 18, thereby causing the distal end 21b to shift as shown in FIG. It can rotate together with the rod 2 in the same direction (direction perpendicular to the axial direction of the shift rod 2).

Further, a damper mechanism 22 is provided in the lower part of the casing 19 separately from the shift rod 2 in association with the damper force applying member 21. This damper mechanism 22
As shown in FIG. 3, the damper housing 23 has a hollow damper housing 23 fixed to the lower surface of the casing 19, and an insertion opening 24 is formed in the upper surface of the housing 23 in correspondence with the opening 20 of the casing 19. ing. Damper housing 2
3 is provided with two upper and lower chambers defined by a partition wall 25 extending in the horizontal direction, and the upper chamber is a pressure fluid chamber 26 filled with pressure fluid. A damper piston 27 is slidably disposed in the lower chamber, and the damper piston 27 divides two damper chambers 28,
29 are formed on both left and right sides. These damper chambers 28
, 29 are orifices 30, 31 bored in the partition wall 25.
It communicates with the pressure fluid chamber 26 via.

Further, a vertical hole 32 is bored approximately at the center of the damper piston 27 in the axial direction.
By inserting the tip 21b of the damper force applying member 21 into the damper piston 27 and the damper force applying member 21,
are configured so that they are connected to each other. Note that the pressure fluid chamber 26 and the damper chambers 28, 29 are connected to the orifice 30.
, damper piston 2 so as not to communicate at locations other than 31.
It is blocked by 7.

In the transmission operating device of this embodiment, when shifting the transmission (not shown) into gear (when moving from the neutral position to the shift position), first the gear shift lever 4 is moved to the shift rod 2 using the select lever 5. A selection operation is performed by moving it along the axial direction to a desired selection position. Next, when the shift actuator 7 is operated to cause the output rod 9 to slide, the shift rod 2 is rotated from the neutral position by a predetermined amount via the output lever 10 and the rotation lever 6. Along with this,
Since the damper force applying member 21 also rotates in the same direction together with the shift rod 2, the damper piston 27 of the damper mechanism 22
slides to the left, and the pressure fluid in the damper chamber 28 flows into the pressure fluid chamber 26 through the orifice 30 to perform a damping action.

After the shift rod 2 has rotated a predetermined amount from the neutral position, the damper force from the damper mechanism 22 is applied to the shift rod 2 via the damper force applying member 21.
granted to. This damper force acts in the opposite direction to the shift direction of the gear shift lever 4 as a reaction force to the shift operation force, and cancels the shift operation force immediately after the synchronization is completed, eliminating gear collision when shifting gears and ensuring smooth operation. You can perform shift operations.

In the transmission operating device of this embodiment, the damper mechanism 22 is provided separately and independently from the shift rod 2 and is connected to the shift rod 2 via the damper force applying member 21. The problem of poor coaxiality of the damper mechanism 22 does not occur, and the damper action of the damper mechanism 22 is effectively performed, and the presence of the damper mechanism 22 does not impede normal operation.

FIG. 4 shows the second transmission operating device according to the present invention.
This shows an example of the housing 2 of the damper mechanism 22.
A damper force applying member 21 is provided in the lower chamber formed within the damper force applying member 21.
A pair of damper pistons 37 and 38 are slidably disposed facing each other with the tip end 21b of the damper pistons 37 and 38 being disposed in between. These damper pistons 37 and 38 are connected to the damper chamber 28,
The damper force applying member 21 is constantly biased by return springs 39 and 40 provided in the damper force applying member 21 .

Furthermore, communication passages 43 and 44 in which check valves 41 and 42 are arranged are formed inside the damper pistons 37 and 38.
, 42, the pressure fluid chamber 26 and the damper chambers 28, 29 communicate with each other when the check valves 41, 42 are opened. The check valves 41 and 42 are always urged toward the valve seats 43a and 44a by urging springs 45 and 46, and the pressure fluid in the pressure fluid chamber 26 passes through the damper pistons 37 and 38 to the damper chamber 28, However, the pressure fluid in the damper chambers 28 , 29 passes through the damper pistons 37 , 38 and is prevented from flowing into the pressure fluid chamber 26 . The other configurations are almost the same as those of the above embodiment.

In the damper mechanism 22 of this embodiment, when the damper force applying member 21 rotates together with the shift rod 2, for example, clockwise in FIG. The damper piston 37 is the check valve 4
1 remains closed and slides to the left against the biasing force of the return spring 39, the pressure fluid in the damper chamber 28 flows into the orifice 3.
0 into the pressure fluid chamber 26 and a damping effect is performed. On the other hand, when the transmission is shifted out of gear (moved from the shift position to the neutral position), the left damper piston 37 slides to the right by the urging force of the return spring 39, so the shift rod 2 exerts a damper force. Applying member 2
1 and then rotates counterclockwise to return to the neutral position. At this time, the pressure fluid in the pressure fluid chamber 26 is transferred to the communication path 43.
Since the check valve 41 is pushed through the valve, the check valve 41 resists the urging force of the urging spring 45 and separates from the valve seat 43a. Since the pressure fluid chamber 26 and the damper chamber 28 communicate with each other via the communication path 43 of the damper piston 37, the damper piston 37 smoothly moves to the right. Also,
When the damper force applying member 21 rotates counterclockwise in FIG. 4, the damper piston 38 on the right side moves in the opposite direction to the damper piston 37 on the left side, and performs the same operation. Other functions are almost the same as those of the above embodiment.

According to the transmission operating device of this embodiment, the damper pistons 37 and 38 of the damper mechanism 22 are moved to return the shift rod 2 to the neutral position by the urging force of the return springs 39 and 40 when the gear is disengaged. Damper force imparting member 21
Since the front end portion 21b of the lever is pressed, it is possible to perform a speed change operation quickly, and the time required to change the speed can be shortened.

FIGS. 5 and 6 show another first embodiment of the transmission operating device according to the present invention, in which the damper mechanism 22
is provided on the shift actuator 7 side. That is, a rod-shaped damper force applying member 51 that applies the damper force of the damper mechanism 22 to the shift rod 2 via the output rod 9, the output lever 10, and the rotating lever 6 is integrally provided at the lower part of the output lever 10. It is being For this reason,
The damper force applying member 51 is adapted to move in the same direction as the output rod 9 slides.

The damper force imparting member 51 is disposed perpendicular to the output rod 9, and its tip 51a protrudes downward from an elongated hole 52 provided in the lower part of the cylinder housing 8. Thus, the damper force applying member 51 and the damper piston 27 are connected to each other by inserting the tip portion 51a into the vertical hole 32. Note that the elongated hole 52 extends along the axial direction of the output rod 9 to prevent the moving damper force applying member 51 from interfering with the cylinder housing 8. The other configurations are almost the same as the first embodiment of the invention described above.

In the transmission operating device of this embodiment, when the shift actuator 7 is operated to slide the output rod 9 to the left in FIG. 6 to shift the gear of the transmission (not shown), the shift rod 2 is rotated by a predetermined amount from the neutral position via the output lever 10 and the rotation lever 6. Further, since the damper force imparting member 51 also moves in the same direction together with the output rod 9, the damper piston 27 of the damper mechanism 22 slides to the left, and the pressure fluid in the damper chamber 28 passes through the orifice 30 and enters the pressure fluid. A flow dampening effect is provided in the chamber 26.

After the shift rod 2 has rotated a predetermined amount from the neutral position, the damper force from the damper mechanism 22 is applied to the shift via the damper applying member 51, the output rod 9, the output lever 10, and the rotation lever 6. applied to rod 2. This damper force acts in the opposite direction to the shift direction of the gear shift lever 4 as a reaction force to the shift operation force,
It works to cancel the shift operation force immediately after synchronization is completed. Other functions are almost the same as those of the first embodiment of the invention described above.

FIG. 7 shows a second embodiment of a transmission operating device according to another embodiment of the present invention, in which the damper mechanism 22 in the second embodiment of the invention described above is provided on the shift actuator 7 side. . That is, this embodiment uses the damper mechanism 22 shown in FIG. 4 and the damper mechanism 2 shown in FIGS. 5 and 6.
The configuration is a combination of the arrangement structure of 2 and the operation thereof is almost the same, so the explanation will be omitted.

FIG. 8 shows another embodiment of the transmission operating device according to the present invention, in which damper mechanisms 62 and 63 are provided on the left and right extensions of the output rod 9 of the shift actuator 7. There is. The damper housing 64a of the left damper mechanism 62 is formed into a box shape with one end open, and is integrally attached to the side surface of the cylinder housing 8 of the actuator 7. In addition, the damper mechanism 63 on the right side
The damper housing 64b is the same as the left housing 6.
Like 4a, it is formed in a box shape with one end open, and is formed integrally with the casing 17a of the stroke sensor 17. Since the left and right damper mechanisms 62 and 63 have substantially the same configuration, only the left damper mechanism 62 will be described.

Damper housing 64a of damper mechanism 62
There are two upper and lower chambers defined by a partition wall 65 inside, and the upper chamber is a pressure fluid chamber 66 filled with pressure fluid. A damper piston 67 having a flow control valve with a check valve is slidably disposed in the lower chamber, and the damper piston 67 and the housing 64
A damper chamber 68 is formed by the inner wall surface of a. Further, a seal member 69 is provided in the lower chamber to close one end opening of the housing 64a.

The damper piston 67 has a piston rod 70 extending on one side, and the end of the piston rod 70 passes through the seal member 69 and the cylinder housing 8 of the actuator 7 to connect to the free piston 1.
3 and is engaged with the output rod 9 via the free piston 13. However, the piston rod 70 is
A return spring 71 provided in the damper chamber 68 is always biased toward the free piston 13 via the damper piston 67.

On the other hand, a communication passage 73 in which a check valve 72 is disposed is formed inside the damper piston 67. The pressure fluid chamber 66 and damper chamber 68 communicate with each other when the check valve 72 is opened. Further, an orifice 75 is bored in the check valve 72, and the pressure fluid chamber 66 and the damper chamber 68 are constantly communicated through the orifice 75.

The check valve 72 is always urged toward the valve seat 73a by the urging spring 76, and the pressure fluid in the pressure fluid chamber 66 flows into the damper chamber 68 through the damper piston 67. The pressure fluid flows into the pressure fluid chamber 66 only through an orifice 75 in the damper piston 67. However, the flow control valve with check valve is
It is composed of a check valve 72 and an orifice 75. The other configurations are almost the same as the embodiments of the invention described above.

In the transmission operating device of this embodiment, when the shift actuator 7 is operated to slide the output rod 9 to the left in FIG. 8 to shift the gear of the transmission (not shown), FIGS. Shift rod 2 shown in Figure 5
is rotated by a predetermined amount from the neutral position via the output lever 10 and the rotation lever 6. Also, the piston rod 7
Since the damper piston 67 moves in the same direction as the output rod 9 via the free piston 13, the damper piston 67 also moves in the same direction as the output rod 9.
2 remains closed and slides to the left against the biasing force of the return spring 71. Along with this, the pressure fluid in the damper chamber 68 flows into the pressure fluid chamber 66 through the orifice 75 of the check valve 72, the communication path 73 and the through hole 74 of the damper piston 67,
A damper action is performed. After the shift rod 2 has rotated a predetermined amount from the neutral position, the damper mechanism 6
2 is applied to the shift rod 2 via the piston rod 70, free piston 13, output rod 9, output lever 10, and rotation lever 6.

On the other hand, when removing the gear of the transmission,
Since the damper piston 67 slides to the right due to the urging force of the return spring 71, the shift rod 2 is rotated in the opposite direction via the piston rod 70, free piston 13, output rod 9, output lever 10, and rotation lever 6. and return to the neutral position. At this time, since the pressure fluid in the pressure fluid chamber 66 passes through the through hole 74 and the communication path 73 and presses the check valve 67, the check valve 67 resists the urging force of the urging spring 76 and presses the check valve 67 against the valve seat 73a. More disengagement. Since the pressure fluid chamber 66 and the damper chamber 68 communicate with each other via the communication path 73 of the damper piston 67, the damper piston 67 smoothly moves to the right. Other functions are almost the same as those of the embodiments of the invention described above.
