| A transmission system for a vehicle has a first transmission module with at least one speed transforming gear and at least one coupling. The system may further include a second transmission module with at least one speed transforming gear and at least one coupling, wherein an input shaft of the first transmission module is connected to a drive source and an output shaft of the second transmission module iss connected to an end drive. An electromotor may be coupled to the first transmission module and/or the second transmission module, via a mount point. The first transmission module and the second transmission module may be arranged in series with an output shaft of the first transmission module being connected to an input shaft of the second transmission module. | ||||||

| A transmission comprising a primary speed change mechanism including a main shaft provided with a plurality of gears for power transmission, an upper counter shaft and a lower counter shaft disposed in parallel on the opposite sides of the main shaft, the upper counter shaft being provided with a group of speed change gears for running the tractor, the lower counter shaft being equipped with a group of speed change gears for power takeoff. The upper counter shaft is coupled with a secondary speed change mechanism including a bevel pinion shaft which is provided with gears in meshing engagement with gears on the extension of the upper counter shaft and a bevel pinion meshing with a bevel gear. The lower counter shaft also extends in parallel relation to the upper counter shaft and is coupled with a power takeoff shaft so as to provide live power takeoff independent of the speed of the tractor and ground power takeoff in synchronism with the speed of the tractor.

| 154 | Multiple countershafts transmission | US3654822D | 1970-05-01 | US3654822A | 1972-04-11 | SINGER ROBERT B; MUIR EARL B; KOTZAR ANDREW J |
| A gearset including an input shaft, multiple identical countershafts, a quill shaft and appropriate gears and clutches provides choice among multiple paths of power flow to a ring gear and as well as to a sun gear of a set of planetary gearing, the planet gear carrier of the set being connected to an output shaft. In addition, brake means are provided to selectively immobilize the ring gear and the sun gear. The clutches and brakes may be operated in various combinations to provide a progressive series of 32 ratios of speed output to speed input. Gear shift control units may be mounted on the basic transmission assembly interchangeably to provide gear ratios selected from the 32 overall ratios to transform the basic transmission assembly into anyone of five, six, seven, eight, nine, 10, 11, 12, 13 and 15 speed transmissions, there being a family of transmissions available in each category.

| 155 | Variable-ratio positive-drive transmission | US3605515D | 1969-07-29 | US3605515A | 1971-09-20 | LECAVELIER ROBERT EUGENE JULES; TUBEUF JEAN |
| A VARIABLE SPEED POSITIVE-DRIVE POWER TRANSMISSION INCLUDES A POWER GROUP OF GEARS AND AT LEAST TWO COUPLING GROUPS, BOTH OF WHICH ARE COUPLED TO THE POWER GROUPS. THE POWER GROUPS EACH INCLUDE A PRIMARY INPUT SHAFT AND AT LEAST TWO OSCILLATORY SHAFTS. THE OSCILLATORY SHAFTS OPERATE WITH PERIODIC SPEED VARIATIONS AND THEREFORE HAVE VARIABLE REDUCTION RATIOS IN RELATIVE TO THE PRIMARY SHAFT OF THE GROUP. EACH COUPLING GROUP HAS A SECONDARY SHAFT AND EACH SECONDARY SHAFT IS COUPLED TO MOTION TRANSFER POINTS OF THE POWER GROUPS. THE TRANSMISSION IS INTENDED FOR USE WITH LATHES AND OTHER MACHINE TOOLS WHERE VARIABLE OSCILLATORY SPEEDS ARE REQUIRED.
