Abstract
A shifting device for operating the shift lever of a transmission equipped with a synchronizing mechanism in the direction of shift, which comprises a shift actuator for operating the shift lever in the direction of shift, a shift stroke sensor for detecting the shift stroke position of said shift lever, and a control means for controlling the electric power fed to said shift actuator based on a signal from said shift stroke sensor. The control means controls the electric power fed to the shift actuator in response to the shift stroke position detected by the shift stroke sensor.
Claims4
A shifting device for operating a shift lever of a transmission, equipped with a synchronizing mechanism, in the direction of shift to bring the gears of the transmission into engagement or disengagement, said shifting device comprising:
- a shift actuator including an operation member coupled to the shift lever, an operation rod engaged with said operation member, a magnetic moving member on the outer peripheral surface of said operation rod, a cylindrical fixed yoke encircling said magnetic moving member, and a pair of coils arranged side by side in the axial direction inside said fixed yoke;
- a shift stroke sensor for detecting the shift stroke position of the shift lever;
- and
- control means for controlling electric power supplied to said pair of coils of said shift actuator based on a signal from said shift stroke sensor;
- wherein
- said control means controls the electric power supplied to said pair of coils of said shift actuator in response to the shift stroke position detected by said shift stroke sensor.
A shifting device for operating a shift lever of a transmission equipped with a synchronizing mechanism in the direction of shift, comprising:
- an operation member coupled to the shift lever;
- a shift actuator including a first electromagnetic solenoid and a second electromagnetic solenoid for operating said operation member in directions opposite to each other;
- a shift stroke sensor for detecting the shift stroke position of the shift lever;
- and
- control means for controlling electric power fed to said first electromagnetic solenoid and to said second electromagnetic solenoid of said shift actuator based on a signal from said shift stroke sensor;
- wherein:
- said control means controls the electric power supplied to said first electromagnetic solenoid and to said second electromagnetic solenoid of said shift actuator in response to the shift stroke position detected by said shift stroke sensor, and the electric power fed to said first electromagnetic solenoid and to said second electromagnetic solenoid is set based on a target thrust corresponding to the shift stroke position and on a gap between a moving iron core and a fixed iron core of the first electromagnetic solenoid of the second electromagnetic solenoid corresponding to the shift stroke position.
