Abstract
The present invention discloses a gear shifter arrangement configured within a transmission case to switch transmission of input torque from an input shaft to an output shaft through respective gears associated therewith. An idler gear (20) is rotatably supported on an idler shaft (18) which is fixedly mounted on the transmission case. At least one shifter fork, having a hub (29) with a pair of radially extending gripping elements (28), is slidably mounted on the idler shaft (18). The shifter fork is adapted to be slidably displaced on the idler shaft (18) by a linkage mechanism cooperating with a gear actuator.
Claims10
A gear shifter arrangement configured within a transmission case to switch transmission of input torque from an input gear, supported on an input shaft, to at least one output shaft through at least one associated output gear supported thereon, corresponding to a requisite output torque, comprising:
- an idler shaft fixedly mounted on said transmission case, said idler shaft adapted to be parallel to at least one of said input shaft;
- an idler gear rotatably supported on said idler shaft;
- at least one shifter fork slidably mounted on said idler shaft via a hub, said shifter fork adapted to selectively engage with one of the associated output gear via a pair of gripping elements, radially extending from said hub;
- a shifter link functionally engaging with said hub to enable slidably displacing said shifter fork on said idler shaft along a longitudinal axis thereof;
- and
- a linkage mechanism adapted to angularly displace said shifter link to slidably displace said shifter fork, wherein said linkage mechanism is adapted to be supported on the transmission case.
