A shift operation mechanism that performs a shift operation of the transmission includes a select actuator that operates the shift lever in the 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 oil pressure as an operating source is generally used. Select actuators and shift actuators that use this fluid pressure cylinder require piping that connects the fluid pressure source and each actuator, and must also be equipped with an electromagnetic switching valve for switching the flow path of the working fluid. There is a problem that a space for arranging them is required and the weight of the entire apparatus is increased.
In recent years, select actuators and shift actuators constituted by electric motors have been proposed as shift operation devices for transmissions mounted on vehicles that do not include a compressed air source or a hydraulic pressure source. Select actuators and shift actuators composed of electric motors do not require the use of piping or electromagnetic switching valves connected to a fluid pressure source unlike actuators using fluid pressure cylinders, so that the entire device is compact and lightweight. be able to. However, in an actuator using an electric motor, a speed reduction mechanism is required to obtain a predetermined operating force. As this reduction mechanism, a mechanism using a ball screw mechanism and a mechanism using a gear mechanism have been proposed. These actuators using the ball screw mechanism and the gear mechanism are not necessarily satisfactory in terms of the durability of the ball screw mechanism and the gear mechanism, the durability of the electric motor, and the operating speed.

[0024]
In a state where the operating position of the shift plunger 52 is in the neutral position (neutral position) shown in FIG. 5A, currents are passed through the pair of coils 55 and 56 in opposite directions as shown in FIG. 5A. In accordance with Fleming's left-hand rule, thrust is generated in the direction in which the movable magnet 53, that is, the shift plunger 52, cancels each other as indicated by the arrows. Therefore, the shift plunger 52 is maintained at the neutral position (neutral position) shown in FIGS.
[0025]
Next, when a current is passed through the pair of coils 55 and 56 in the same direction as shown in FIG. 5B in a state where the operating position of the shift plunger 52 is in the neutral position (neutral position), the movable magnet 53 That is, a thrust is generated in the shift plunger 52 to the left as shown by an arrow in FIG. As a result, the shift plunger 52 moves to the left in FIG. 4, and the control shaft 32 rotates clockwise in FIG. 4 via the operating lever 50 whose tip is engaged with the shift plunger 52. As a result, the shift lever 34 integrally formed with the shift sleeve 35 attached to the control shaft 32 is shifted in the first direction.
[0026]
Further, when the operating position of the shift plunger 52 is in the neutral position (neutral position), a current is applied to the pair of coils 55 and 56 in the direction opposite to that of FIG. 5B as shown in FIG. When flowing, a thrust is generated in the magnet movable body 53, that is, the shift plunger 52, as shown by an arrow in FIG. As a result, the shift plunger 52 moves rightward in FIG. 4, and the control shaft 32 rotates counterclockwise in FIG.

That is, thrust is generated in the shift plunger 52 in a direction that cancels each other as indicated by an arrow. At this time, in a state where the shift plunger 52, that is, the magnet movable body 53 is moved to the left, a magnetic flux passing through the coil is generated by the first magnetic flux circuit 537 and the second magnetic flux circuit 538 formed by the permanent magnet 532. However, the amount of magnetic flux passing through the coil 56 is larger than the amount of magnetic flux passing through the coil 55. Therefore, when a current is passed through the other coil 56 in the direction shown in FIG. 5D, the rightward thrust generated in the movable magnet 53, that is, the shift plunger 52, is applied to the one coil 55 in FIG. When a current is passed in the direction shown in d), it becomes larger than the leftward thrust generated in the movable magnet 53, that is, the shift plunger 52. As a result, the shift plunger 52 moves to the right in FIG. Thus, when the shift plunger 52 moves to the right in FIG. 5D, the amount of magnetic flux passing through the coil 55 decreases and the amount of magnetic flux passing through the coil 56 increases as it approaches the neutral position (neutral position). To do. When the shift plunger 52 reaches the neutral position (neutral position), the amount of magnetic flux passing through the coils 55 and 56 becomes equal. As a result, the leftward thrust and the rightward thrust generated in the shift plunger 52 are the same. As a result, the shift plunger 52 stops at the neutral position (neutral position).
[0028]
As described above, the shift actuator 5 in the embodiment shown in FIG. 4 operates according to the principle of a linear motor in which the shift plunger 52 includes the magnet movable body 53, the fixed yoke 54, and the pair of coils 55 and 56.

Therefore, the shift sleeve 35 moves to the right in FIGS. 1 and 2 against the spring force of the coil spring 473 after contacting the moving ring 474 and is stopped at the position where the moving ring 474 contacts the stopper 475. The Accordingly, the shift lever 34 integrally formed with the shift sleeve 35 is positioned at the first select position SP1. The time for operating the select actuator 3 to the first select position SP1 (first speed-reverse select position) may be about 0.2 sec. When the select actuator 3 is operated to the first select position SP1 (first speed-reverse select position), the switching transistors 203f (Tr5), 203g (Tr6), and 203h (Tr7) on the shift actuator drive circuit 21 side. , 203j (Tr8) are turned off except that the switching transistor 203h (Tr7) as the shift backup operation means is turned on.

The time for operating the shift actuator 5 in the first shift direction may be about 1 sec. When the shift actuator 5 is operated in the first shift direction, each switching transistor on the select actuator drive circuit 11 side maintains the operation state to the first select position SP1 (first speed-reverse selection position). is doing. Thus, when the shift operation to the reverse speed (R), which is the target shift speed instructed by the target shift speed indicating means 205 (GPS), is completed, the switching transistor 203b (Tr2) as the select backup operating means and the shift All the other switching transistors 203a (Tr1) 203c (Tr3), 203d (Tr4), 203f (Tr5), 203g (Tr6), 203j (Tr8) except that the switching transistor 203h (Tr7) as the backup operation means is turned on.
