Abstract
A transmission shift system for idler wheels comprising at least one actuating device that actuates a respective sliding sleeve non-rotatably connected with a main shaft in order to bring the sliding sleeve to positive fit with an idler wheel to be shifted. It is provided that the shiftable idler wheel is disposed upon the main shaft directly juxtaposed in axial direction and that the respective actuating devices are provided as unit on the main shaft outside the group of idler wheels, each actuating device being connected with the respective sliding sleeve via at least one connecting element extending along the main shaft.
Claims19
A transmission shift system for idler wheels, comprising a plurality of actuating devices which each actuates a respective sliding sleeve non-rotatably connected with a main shaft in order to bring the sliding sleeve (2) to positive fit with one of a plurality of idler wheels (1) to be shifted,
- wherein the shiftable idler wheels (1) are disposed upon the main shaft (4) directly juxtaposed in an axial direction, and the respective actuating devices are provided as a unit on the main shaft (4) axially outside the plurality of idler wheels (1);
- and each actuating device is connected with the respective sliding sleeve (2) via at least one connecting element extending along the main shaft (4).
A transmission shift system for idler wheels comprising:
- a main shaft non-rotatably connected with a plurality of actuatable sliding sleeves (2), the sliding sleeves (2) actuated by a respective actuating device having a shift fork (3) and a shift plate (7);
- one of a plurality of shiftable idler wheels (1) to be shifted, in communication with one of the plurality of actuatable sliding sleeves (2), the plurality of shiftable idler wheels (1) are axially juxtaposed on the main shaft and directly adjacent each other;
- and
- at least one connecting element extending along the main shaft (4) connects each respective actuating device and the one of the plurality of actuatable sliding sleeves (2), each actuating device is provided as a unit along the main, shaft (4) axially outside the plurality of the shiftable idler wheels (1).
A transmission shift system for idler wheels, comprising a plurality of actuating devices, each actuating device having a shift fork (3) and a shift plate (7), each actuating device actuates a respective sliding sleeve non-rotatably connected with a main shaft in order to bring the sliding sleeve (2) to positive fit with one of a plurality of idler wheels (1) to be shifted, wherein the shiftable idler wheels (1) are disposed upon the main shaft (4) directly juxtaposed in axial direction, and that respective actuating devices are provided as a unit on the main shaft (4) axially outside the plurality of idler wheels (1), each actuating device being connected with the respective sliding sleeve (2) via at least one connecting element extending along the main shaft (4);
- wherein the at least one connecting element is a connecting rod (8) and is provided in predetermined grooves (10) of a spline section (9) of the main shaft (4).
