Problems solved by technology

[0006] Therefore, it becomes an obstacle to the cost reduction and miniaturization of the hybrid drive device. In particular, the electric oil pump hinders the further improvement of the fuel consumption even though the hybrid device is implemented to improve the fuel consumption.
[0007] Although it is also considered to apply the above-mentioned cone-ring CVT to the continuously variable transmission device for the hybrid drive device, there is no prior art related to the combination of the cone-ring CVT and the electric motor, and the application of the cone-ring CVT cannot be established. CVT technology applied to hybrid drive

Embodiment Construction

[0040] A hybrid drive device to which the present invention is applied will be described based on the drawings. Such as figure 1 and figure 2As shown, the hybrid drive device 1 has: an electric motor 2; a conical friction ring type continuously variable transmission device (conical ring type CVT) 3; a differential device 5 constituting an output member; the input shaft 6 to which the output shaft 54 ​​is coupled; and the wheel transmission 7 . The respective devices and shafts described above are accommodated in a case 11 obtained by combining two case members 9 and 10 , and the case 11 is divided into a first space A and a second space B by a partition wall 12 in an oil-tight manner.

[0041] The electric motor 2 has a stator 2 a fixed to the first case member 9 and a rotor 2 b provided on the output shaft 8 , one end of the output shaft 8 is rotatably supported by the first case member 9 via a bearing 13 , and the other One end portion is rotatably supported by the seco...

Abstract

Disclosed is a hybrid drive device that eliminates an electric oil pump and further improves fuel consumption. Via a cam mechanism (28), a cone-ring CVT (3) provides axial force that clamps a ring (25) between a pair of friction wheels (22, 23). The ring (25) is moved in the axial direction by a gearshift operation means, which is provided with an electric actuator (A2). A clutch (4) is operated by an operation means (51), which is provided with an electric actuator (A1). The cone-ring CVT (3) is lubricated by the rotation of the ring (25), which is immersed in an oil pan. In a gear transmission device (7), the oil of the oil pan is scooped by a ring gear (41).

Description

technical field [0001] The present invention relates to a hybrid drive device capable of driving wheels by an engine and an electric motor. Specifically, it relates to a hybrid drive device in which an electric motor and a conical friction ring type continuously variable transmission (cone ring type CVT) are integrally assembled. Background technique [0002] Conventionally, as a hybrid drive device that drives wheels using an engine and an electric motor, a drive device that combines a single electric motor and a continuously variable transmission is known. In general, as a continuously variable transmission device for this hybrid drive device, a metal belt (or chain) including a pair of pulleys and a metal belt (or chain) wound around the pair of pulleys is known. By changing the effective diameter of the pulleys, A belt-type continuously variable transmission device for continuously variable transmission. [0003] On the other hand, there is known a cone-ring type CVT th...
