Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shift operating device for performing a shift operation of a transmission mounted on a vehicle.

[0002]

2. Description of the Related Art A shift operating device for performing a shift operation of a transmission includes a select actuator that operates a shift lever of a transmission mechanism in a select direction, and a shift actuator that operates the shift lever in the shift direction.
As such a select actuator and a shift actuator, a fluid pressure cylinder using a fluid pressure such as air pressure or hydraulic pressure as an operation source is generally used. Select actuators and shift actuators that use this fluid pressure cylinder require pipes that connect the fluid pressure source and each actuator, and also need to provide an electromagnetic switching valve for switching the flow path of the working fluid. However, there is a problem that a space for arranging them is required and the weight of the entire device becomes heavy. Further, in recent years, as a shift operation device for a transmission mounted on a vehicle that does not have a compressed air source or a hydraulic pressure source, a select actuator and a shift actuator configured by an electric motor have been proposed. Select actuators and shift actuators configured by electric motors do not require piping or electromagnetic switching valves connected to a fluid pressure source unlike actuators using fluid pressure cylinders, so the entire device is compact and lightweight. be able to.

[0003]

An actuator using an electric motor requires a speed reduction mechanism to obtain a predetermined operating force. As the speed reducing mechanism, one using a ball screw mechanism and one using a gear mechanism have been proposed. An actuator using the ball screw mechanism and the gear mechanism is not always satisfactory in durability of the ball screw mechanism and the gear mechanism, durability of the electric motor, and operating speed.

The applicant of the present application filed for a gear shift operating device using an electromagnetic solenoid as a drive source of a select actuator and a shift actuator which can operate a shift lever in a shift direction and a select direction without using a reduction mechanism or the like. Proposed as 2001-183470.
Therefore, in the select actuator, it is necessary to surely position the shift lever at a plurality of select positions, which requires a considerably long operation stroke. On the other hand, the thrust of the electromagnetic solenoid is inversely proportional to the distance between the fixed iron core and the movable iron core,
As this distance decreases, it increases quadratically,
If the distance between the fixed core and the movable core is long, a large thrust cannot be obtained. That is, when an electromagnetic solenoid is used as a drive source of a select actuator that requires a considerably long operation stroke, the thrust generated at a position where the distance between the fixed iron core and the movable iron core is long is small. Therefore, in order to obtain a predetermined thrust at a position where the distance between the fixed iron core and the movable iron core is long, it is necessary to use a large capacity electromagnetic solenoid in order to increase the electric power supplied to the electromagnetic solenoid.

The present invention has been made in view of the above facts, and its main technical problem is to provide an electromagnetic solenoid capable of obtaining a predetermined thrust even when the shift lever has many select positions and a long operation stroke is required. An object of the present invention is to provide a gear shift operation device including the select actuator used.

[0006]

According to the present invention, in order to solve the above technical problems, a select actuator for operating a shift lever in a select direction and a shift actuator for operating the shift lever in a shift direction are provided. In the gear shift operation device, the select actuator includes a cylindrical casing, a control shaft rotatably supported in the casing and having a shift lever slidably mounted in the axial direction, and the shift shaft in the casing.

1 and 2 in which the spring forces of the first compression coil spring 623 and the second compression coil spring 624 forming the select position restricting means 62 are balanced.

From the state shown in FIGS. 1 and 2, to the electromagnetic coil 41 constituting the first electromagnetic solenoid 4, for example, 2.4.
When a voltage of V is applied, the fixed iron core 42 is excited and the movable iron core 43 is attracted to the fixed iron core 42, and a thrust to the left in the figure is generated. As a result, as shown in FIG. 4A, the shift lever 34 constitutes the second select position restricting means 62 by the operating rod 44 attached to the movable iron core 43, and the first compression coil spring 623 and the second compression coil spring 623. It moves on the control shaft 32 leftward in the figure against the spring force of the compression coil spring 624. At this time, since the spring force of the second compression coil spring 624 is set to be larger than the spring force of the first compression coil spring 623, the moving ring 621 is not displaced. Then, the shift lever 34
Stops at a position where the left end of the mounting portion 341 in the drawing contacts the moving ring 621 that constitutes the second select position restricting mechanism 62. As a result, the shift lever 34
It is positioned in the second operating position (P2) as shown in FIG.

Next, when a voltage of, for example, 4.8 V is applied to the electromagnetic coil 41 which constitutes the first electromagnetic solenoid 4,
The thrust to the left generated in the movable iron core 42, that is, the operating rod 43, increases. As a result, as shown in FIG. 4B, the shift lever 34, which is in contact with the operating rod 44, has the spring force of the second compression coil spring 624 in a state in which the mounting portion 341 of the shift lever 34 is in contact with the moving ring 621.

Next, from the state shown in FIG. 1 and FIG.
When a voltage of, for example, 2.4 V is applied to the electromagnetic coil 51 constituting the electromagnetic solenoid 5, the fixed iron core 52 is excited and the movable iron core 53 is attracted to the fixed iron core 52, and a thrust force to the right in the figure is generated. As a result, as shown in FIG. 4C, the operating lever 54 mounted on the movable iron core 53 causes the shift lever 34 to move to the first select position restricting means 6.
The first compression coil spring 613 and the second compression coil spring 614 forming part 1 are moved to the right on the control shaft 32 against the spring force. At this time,
Since the spring force of the second compression coil spring 614 is set to be larger than the spring force of the first compression coil spring 613,
The moving ring 611 is not displaced. Then, the shift lever 34 stops at the position where the right end of the mounting portion 341 in the drawing abuts the moving ring 611 that constitutes the first select position restricting mechanism 61. As a result, the shift lever 34
Is the third operating position (P3) as shown in FIG. 4 (c).
Located in.

Next, when a voltage of, for example, 4.8 V is applied to the electromagnetic coil 51 forming the second electromagnetic solenoid 5,
The thrust to the left generated in the movable iron core 53, that is, the operating rod 54, increases. As a result, as shown in FIG. 4D, the shift lever 34 is brought into contact with the operating rod 54, and the shift lever 34 is subjected to the spring force of the second compression coil spring 614 in a state where the mounting portion 341 of the shift lever 34 is brought into contact with the moving ring 611. Move to the right in the figure against. Then, the moving ring 611 becomes the stopper 61.
Stop at the position where it abuts 2. As a result, the shift lever 34 is moved to the fourth operating position (P
Positioned in 4).

As described above, the select actuator 3 which constitutes the gear shift operation device 2 is provided with the pair of electromagnetic solenoids, that is, the first electromagnetic solenoid 4 and the second electromagnetic solenoid 5, as the drive source, and therefore each of them is provided.
