Embodiment Construction

[0020] figure 1 2 schematically shows a motor vehicle drive train according to the invention with a drive motor 1 , a transmission 2 , in particular a cascade transmission or a continuously variable transmission, and drive wheels 3 driven by the drive motor 1 via the transmission 2 . Correspondingly, the main road 4 of the drive train of the motor vehicle extends from the drive motor 1 via the transmission input shaft 5 , the transmission output shaft 6 and the usual cardan shaft 5 on the differential drive 8 to the driven wheels 3 .

[0021] The transmission 2 has an auxiliary drive train on the secondary side with an auxiliary output shaft 9 which is drivingly connected to the transmission drive shaft 6 via a spur gear pair. With regard to the connection of the hydraulic gear unit 10 or its rotor shaft 11 , the auxiliary output shaft 9 is at the same time the intermediate shaft 12 of the connection according to the invention.

[0022] The countershaft 12 has a disconnect cl...

Abstract

The invention relates to a drive train of a motor vehicle with a drive motor and with drive wheels, wherein the drive wheels are driven by the drive motor via a trunk, with a hydraulic reducer comprising a rotating rotor and a stator or a rotating rotor and a counter-rotor rotating in the opposite direction to the rotor, which together form a working space filled or capable of being filled with a working medium, with a disconnect clutch, by means of which the rotor of the hydraulic reducer can be driven from The drive power flow in the system is disconnected. The invention is characterized in that the hydraulic reducer is connected to the main road through at least two stages of transmission, comprising at least one intermediate shaft and a rotor shaft, wherein the rotor shaft drives or supports the rotor and the intermediate shaft and the main road form at least one first transmission stage And together with the rotor shaft, at least one second transmission stage is formed, and the disconnect clutch is positioned on the intermediate shaft.

Description

technical field [0001] The invention relates to a drive train of a motor vehicle with a hydraulic retarder. Background technique [0002] In motor vehicle drive trains, in particular of trucks, hydraulic retarders have already been proposed as wear-free permanent braking devices. However, the acceptance of hydraulic brakes by commercial vehicle manufacturers is based on the fact that such hydraulic brakes have extremely low idling losses during non-braking operation. In order to reduce the idling losses during non-braking operation, various measures are usually taken. One of these measures is the provision of so-called ventilation baffles which are inserted into the gap between the rotor and the stator during non-braking operation, thereby preventing the circulation of air or air-residual working medium-mixture. Further measures provide that during the transition from braking operation to non-braking operation the rotor moves away from the stator or vice versa, but in the ...
