Embodiment Construction

[0031] Fig. 1 shows a differential torque converter transmission 1 as a typical example of an automatic transmission according to the background art belonging to this category. Torque converter 2 can be seen in the middle. On the left side of Figure 1, next to the torque converter is the drive zone 3, which in the case shown here has the planetary gear sets 4 and 5 normally present. On the right side of the torque converter 2 in FIG. 1, the driven area 6 can be seen, which also has two planetary gear sets 7, 8 according to the background art. The structure shown in FIG. 1 is a currently commonly used structure of a differential torque converter gearbox, in which the torque converter is applied to the first forward gear and the reverse gear, and is used as a wear-resistant continuous brake or reducer. However, the disadvantage of such a gearbox is that during braking, especially when braking at a high speed, the torque converter 2 generates a large load, which in turn causes th...

Abstract

An automatic transmission is provided, which has a drive area, a hydrodynamic converter, and a driven area. In such a transmission, there are power paths via both the hydrodynamic converter, purely mechanical power paths around the hydrodynamic converter and combined power paths. It is provided in accordance with the invention that precisely one planetary gear set is provided in the driven area. A braking means is further provided which is suitable for tightly holding the turbine of the hydrodynamic converter.

Description

Technical field [0001] The invention relates to an automatic gearbox, which has both a force transmission path passing through a hydraulic torque converter and a purely mechanical force transmission path surrounding the hydraulic torque converter, as well as a combined force transmission path. In addition, the present invention also relates to a method of using such an automatic transmission to perform braking at high speeds. Background technique [0002] Ordinary automatic transmissions are generally well known. For example, see DE2021543A1 here. This patent describes a combined hydraulic-mechanical gearbox for vehicles, which distributes the tractive power to the power transmission path and parallel with a hydraulic torque converter by means of a differential gearbox. On the mechanical transmission path here, the traction power is integrated into the common transmission path. In this case, the gearbox has mechanical and / or mechanically and / or common power transmission paths, ...
