Continuous and reversible mechanical gear system with a power branch

摘要

A continuous and reversible mechanical transmission system with a power branch, with an input shaft (17) and an output shaft (16), formed by a continuously variable transmission (1) connected to the shaft of the motor and by at least one planetary gear train (2) linked to the shaft of the motor (17) and to the continuously variable transmission. The continuously variable transmission includes a first pair of gears (3 and 4) linked by means of a transmission (5). The gear train (2) comprises a second pair of gears (6-7) linked by a transmission (8) and at least a first and second transmission step (9-10), each one of which comprises an epicyclic gear carrier (9-13) and a pair of epicyclic gears (12-14).

1. A continuous and reversible mechanical transmission system with a power branch, comprising a continuously variable transmission connected to an input shaft and at least one planetary gear train, which is linked to the shaft and to the continuously variable transmission, this continuously variable transmission including a first pair of gears, which are joined to one another by means of a mechanical transmission, the gear train of which comprises a second pair of gears, which are joined to one another by means of a mechanical transmission, being driven by the first pair of gears; at least a first transmission step and a second transmission step, each one of which comprises a sun gear and a pair of epicyclic gears, the sun gear of the first step being driven by the second pair of gears and the sun gear of the second step being connected to the shaft, whilst the pairs of epicyclic gears of the first and second steps are joined to one another and are mounted to an epicyclic gear carrier with an output shaft.
