Embodiment Construction

[0039] will now refer to figure 1 , figure 2 and image 3A hybrid powertrain 1 for a motor vehicle (not shown) according to an embodiment of the present invention will be described. The drive train 1 includes an internal combustion engine 3 (shown only schematically) and an electric machine 5 . like figure 1 As shown in , an internal combustion engine 3 and an electric machine 5 are coupled to a transmission 7 with an integrated torque converter 9 . The transmission 7 in this embodiment is an automatic transmission, but the transmission 7 may equivalently be a manual transmission.

[0040] The electric machine 5 is a traction motor for providing traction to propel the vehicle. The electric machine 5 includes a first housing 10 arranged between the internal combustion engine 3 and the transmission 7 . The internal combustion engine 3 includes a second (engine) housing 11 , and in the present embodiment, the first housing 10 is mounted to the second housing 11 . It will ...

Abstract

The present invention relates to a hybrid vehicle powertrain (1). The powertrain (1) includes an internal combustion engine (3), an electric traction motor (5) and a transmission (7). A first flexible coupling (55) drivingly connects the internal combustion engine (3) to the transmission (7). A second flexible coupling (65) drivingly connects the electric traction motor (5) to the transmission (7). The first and second flexible couplings may comprise flex plates of differing levels of flexibility. The present invention also relates to a dual coupling including first and second flexible couplings (55, 65). Furthermore, the present invention relates to a vehicle incorporating a powertrain (1).

Description

technical field [0001] The present invention relates to a powertrain of a hybrid vehicle. Aspects of the invention relate to a powertrain, to a coupling, and to a motor vehicle. Background technique [0002] It is known to provide hybrid vehicles having an internal combustion engine for operation in conjunction with an electric traction motor. The internal combustion engine and electric traction motor can be operated independently of each other or together to increase maximum torque output. One approach is to develop integrated transmissions, where the electric traction motor is incorporated into the transmission. However, a particular integrated transmission may not be suitable for all applications, necessitating the development of alternative transmissions. At least from a commercial standpoint, it is desirable to retain the option to use a conventional transmission (ie, one that does not include an integrated electric traction motor) in combination with a hybrid powert...
