Abstract
A transmission shift rail with a control rail 12 and shift fork 30. A pin 26 extends into a translation slot 36 in the shift fork 30 to produce axial movement of the shift fork 30 when the control rail 12 rotates, without translating the shift fork 30 when the control rail 12 translates.
Claims31
A transmission shift rail, comprising:
- a control rail;
- a shift fork;
- means for preventing translation of the shift fork when the control rail is translated;
- and
- means for translating the shift fork when the control rail rotates.
A manual transmission having an input shaft, a countershaft, an output shaft, and a pinion and gear pair, comprising:
- a control rail;
- a shift fork;
- means for preventing translation of the shift fork when the control rail is translated;
- means for translating the shift fork when the control rail rotates;
- and
- a first synchronizer axially moveable by the shift fork for producing an output ratio to the output shaft.
A manual transmission with a double disconnect having an input shaft, a countershaft, an output shaft, an input gear and an output gear, comprising:
- a shift rail having a control rail, a first shift fork and a means for translating the first shift fork when the control rail rotates;
- a second shift fork axially moveable when the control rail moves axially;
- a first synchronizer for drivably connecting and disconnecting an output gear;
- and
- a second synchronizer for drivably connecting and disconnecting an input gear.
A method of axially moving a synchronizer during a crossover shift, comprising the steps of:
- providing a control rail;
- providing a shift fork;
- providing a means for preventing translation of the shift fork when the control rail is translated;
- and
- providing a means for translating the shift fork when the control rail rotates.
