Embodiment Construction

[0027] figure 1 A hybrid electric vehicle 10 is illustrated, schematically represented as a parallel hybrid electric powertrain. The hybrid electric vehicle is provided with an engine 12 having a rotational output of a disconnect clutch 14 connected to a drive motor 16 . The output of the electric motor is connected to the input of torque converter 18 , and the output of the torque converter is connected to the input shaft of automatic transmission 20 . In conventional fashion, the automatic transmission is connected by a differential 24 to the drive wheels 22, 22'. In the illustration, the hybrid electric vehicle 10 is provided with a pair of non-driven wheels, however, a transfer case and a second differential may alternatively be utilized to actually drive all the wheels of the vehicle. The engine, disconnect clutch, electric motor, torque converter and automatic transmission are sequentially connected in series, as figure 1 shown in .

Abstract

A method of assembling a powertrain comprising installing a transmission and an input shaft on a housing, installing bearings in a pump housing, and securing the pump housing to a pump plate, positioning the pump plate on the housing, passing through the input shaft The stator shaft is positioned on the pump casing, and the rotor shaft is mounted through the stator shaft, the rotor hub engaging the bearing and the clutch hub.

Description

technical field [0001] The present application relates to powertrains of hybrid electric vehicles, and more particularly to methods of assembling powertrain components. Background technique [0002] Hybrid electric vehicles (HEVs) have an internal combustion engine and an electric motor that can be used alternately or in combination to propel the vehicle. A variety of different drive trains are used in hybrid vehicles. The invention relates to a parallel configuration where the engine is connected by a disconnect clutch to an electric motor which drives the torque converter input of an automatic hydraulic transmission. The fluid transmission has an output connected to a differential coupled to the two drive wheels of the vehicle. Drive train power flow arrangements for such parallel hybrid electric vehicles are known in the art. [0003] The problem facing HEV designers is how to cool the disconnect clutch and the rotor and stator sections of the electric motor. Various ...
