Embodiment Construction

[0013] in figure 1 The hybrid drive device 1 with the dual-clutch transmission 2 can be clearly seen. The dual clutch transmission 2 and the hybrid drive device 1 are part of a drive train that is not shown in detail of a motor vehicle, which is not shown in detail. The hybrid drive device 1 has a motor 3. The motor 3 is designed as a rotary piston, and has a rotatable rotor 4 and a stator 5 fixed on the housing. The motor 3 can work as a generator or a motor.

[0014] In addition, the hybrid drive device 1 also has a drive shaft 6. The drive shaft 6 may be driven by an internal combustion engine (not shown). The drive shaft 6 is connected with the dual inertia flywheel 7. The drive shaft 6 can be functionally and effectively coupled with the rotor 4. The drive shaft 6 can be coupled or decoupled by means of the disconnect clutch K0. As a result, the internal combustion engine can be coupled or decoupled by means of the disconnect clutch K0. The design solution is preferab...

Abstract

The invention relates to a hybrid drive (1) for a motor vehicle with an electric machine (3), wherein the electric machine (3) has a rotor (4) and a stator (5), wherein the rotor (4) is associated with a separating clutch (K0), wherein a drive shaft (6) drivable by the internal combustion engine is provided, wherein the drive shaft (6) can be coupled to the rotor (4) by means of a separating clutch (K0), wherein at least one transmission input shaft (8 , 9) each can be coupled to the rotor (4) via a friction clutch (K1, K2), wherein the separating clutch (K0) and at least one friction clutch (K1, K2) are arranged in a common wet chamber (36), wherein , the coolant supply system (17) has a coolant pipe (18) for supplying the coolant (27) to the wet chamber (36), and wherein the coolant pipe (18) is connected into the wet chamber (36). The coolant line (18) leads to the separating clutch (K0), wherein the coolant (27) can be guided, in particular can be pressed into the separating clutch (K0), thereby avoiding supplying the separating clutch (K0) with coolant ( 27) Delay.

Description
