Abstract
A multi ratio reversing powershiftable transmission having an input shaft, an output shaft, a plurality of countershafts, a drive wheel set, a distribution wheel set and a driven wheel set. The set of drive wheels includes a driven idler gear on each countershaft which can be optionally non-rotatably connected with the contershaft to cause a change of gear and direction of the transmission. The set of distribution wheels consist of at least one fixed gear on each countershaft for commutating rotation between communicating countershafts and the fixed gears of the set of driven wheels which in turn drive the output shaft.
Claims9
A multi-ratio reversing powershiftable transmission (1) comprising:
- at least one input shaft (3, 7), having a fixed drive gear (11);
- a plurality of countershafts (16, 17, 18, 23, 24 and 25), each supporting a single clutch (19, 20, 21, 29, 31 and 41) and an idler gear (13, 14, 15, 40, 30, 28) which can be optionally non-rotatably connected with one of each said countershafts for a change of gear and direction;
- a set of drive wheels (12) consisting of said fixed drive gear (11) in constant mesh with more than one of said idler gears;
- a set of distribution wheels (35) consisting of a plurality of fixed gears (26, 27, 36, 37, 38 and 39) and one of said idler gears (28) for commutating rotational communication between said countershafts;
- a set of driven wheels (34) having at least one fixed driven gear (32) in constant mesh with at least two said idler gears (30, 40) for driving an output shaft.
