Problems solved by technology

[0005] These fixed-ratio designs have a number of disadvantages, for example, the electric motor / generator unit realizes its role in generating electricity and providing additional power to the wheels or the main shaft of the internal combustion engine only within a relatively narrow range of rpm of the motor / generator unit. The most efficient operation of both

Embodiment Construction

[0022] Detailed description of the preferred embodiment

[0023] Preferred embodiments will now be described with reference to the drawings, wherein like reference numerals refer to like parts throughout. The terminology used in the following description should not be interpreted in any restrictive or restrictive manner, simply because it is used in connection with the detailed description of certain specific embodiments. Furthermore, the embodiments may contain several novel features, no single one of which is responsible for the desirable attributes or essential to the practice of the described embodiments.

[0024] This powertrain relates to electric powertrain configurations and structures to be used in hybrid vehicles. The powertrain and / or drivetrain configuration uses transmissions to combine power sources used in hybrid vehicles, such as combustion engines (internal or external combustion engines), motors, generators, batteries, and gear transmissions. The powertrain...

Abstract

An electric axle having an electric drivetrain including a motor / generator, a first planetary gear set operably coupled to the motor / generator, and a second planetary gear set operably coupled to thefirst planetary gear set, wherein the first planetary gear set includes a first ring gear, a first planet carrier, and a first sun gear, and wherein the second planetary gear set includes a second ring gear, a second planet carrier, and a second sun gear; a drive wheel axle operably coupled to the electric drivetrain; and a first wheel and a second wheel coupled to the drive wheel axle.

Description

[0001] related application [0002] This application claims U.S. Provisional Patent Application No. 62 / 428,127, filed November 30, 2016, U.S. Provisional Patent Application No. 62 / 434,015, filed December 14, 2016, and Priority to US Provisional Patent Application No. 62 / 452,714, the entire contents of which are incorporated herein by reference. Background technique [0003] Due in large part to the cost of fuel and government regulations on greenhouse gas emissions from internal combustion engine vehicles, hybrid vehicles are growing in popularity and acceptance. Such hybrid vehicles include an internal combustion engine and an electric motor for propelling the vehicle. [0004] In current electric axle designs for consuming and storing electrical energy, the rotating shaft from the combined electric motor / generator is coupled to the wheels by a gear train, planetary gear set. Accordingly, the rotating shaft of the electric motor / generator unit rotates in unison with the whe...
