Two-speed clutch with reverse clutch function

Abstract

The invention discloses a dual-speed clutch device with a reverse clutch function. The dual-speed clutch device with the reverse clutch function comprises an input planetary mechanism, an output planetary mechanism, a high-gear brake disc, a low-gear brake disc, a reverse clutch brake disc and a tank, wherein the input planetary mechanism and the output planetary mechanism are coaxially installed in the tank; the output planetary mechanism is connected with the high-gear brake disc, the low-gear brake disc and the reverse clutch brake disc which are installed on the outer side of the tank; the high-gear brake disc is used for controlling the dual-speed clutch device to operate at a high gear; the low-gear brake disc is used for controlling the dual-speed clutch device to operate at a low gear; and the reverse clutch brake disc is used for controlling the dual-speed clutch device to achieve reverse output. When the high-gear brake disc, the low-gear brake disc and the reverse clutch brake disc are completely released, the dual-speed clutch device operates in a completely disengaged mode, and when any two of the high-gear brake disc, the low-gear brake disc and the reverse clutch brake disc are switched off, the dual-speed clutch device operates in a completely braking mode. The dual-speed clutch device with the reverse clutch function has high oil saving rate, reliability and transmission efficiency, better controllability and lower cost.

Description

technical field [0001] The invention relates to the field of vehicle transmission equipment, in particular to a two-speed clutch device with a reverse clutch function. Background technique [0002] Vehicle emissions and energy consumption have become a worldwide problem. Therefore, high-efficiency, low-loss, high-reliability and multi-gear vehicle transmission systems have become one of the current research and development hotspots in the automotive industry, especially diesel-powered trucks and buses. For medium- and heavy-duty vehicles, higher fuel efficiency, higher reliability, lower emissions, lower maintenance costs and lower costs have become the core constraints on this type of automotive industry. In order to improve vehicle power, comfort, fuel efficiency, and low cost, gearboxes are developing towards more gears, automatic shifting, and simpler mechanisms. However, the gearbox MT increases from 5th gear to 6th gear, and from 6th gear to 8th gear. Not only the ent...

Similarly, increasing the AMT gear not only requires a large adjustment of the gearbox structure, but also increases the complexity of the control system with each additional gear.

For DSG, two 1:1 constant speed clutches are used to realize odd and even gear interchange. However, it is hindered in terms of linear control, high power transmission, service life, and low cost.
