Turbo reverse gear, solely hydraulically operated and comprising turbines of start-up converter and working converter driven with lay shaft

摘要

The impellers (5, 6, 7, 8) of the torque converter are driven using the spur gears (2, 3, 4) and the hollow shafts. The secondary wheel (10) with a counter wheel (17) is moved with a hollow shaft by the turbine (9) of a first converter, the turbine (11) of the second converter drives a second wheel (12) with a counter wheel (18). The secondary wheel (14) is driven by the turbine (13) using a central shaft. The counter wheels are permanently joined to the related lay shafts. The spur gear (17) engages with the spur wheel (21) of the output lay shaft, driving the output shaft (24) with the spur gears (22, 23). For reversing the spur gear (18) engages with the spur gear (18) via a transitional wheel.
