Problems solved by technology

However, since the space available on the rear axle is usually very limited, it is necessary to set up a very compact layout of the electric axle
This becomes more difficult in hybrid applications where the exhaust system of the internal combustion engine must pass through the electric shaft

Abstract

An electrical axle for a four wheeled road vehicle is provided. The electrical axle comprises an electrical propulsion motor (110) arranged coaxially on said axle (100), a differential mechanism (120) being connected to said electrical propulsion motor for driving two wheels arranged on a first side (160) and a second side (162) of said electrical axle (100), and an electrical torque vectoring motor (132) arranged coaxially on said axle (100) and connected to said fist side (160) and second side (162) for providing a change in torque distribution between said first side (160) and said second side (162) of said axle (100), wherein the diameter of the torque vectoring motor (132) is less than the diameter of the electrical propulsion motor (110).

Description

technical field [0001] The invention relates to an electric axle of a four-wheeled vehicle. More specifically, the present invention relates to an electric axle having a torque vectoring device for providing a torque differential between right and left wheels of said electric axle. Background technique [0002] There is an increasing demand for the supply of four-wheeled vehicles, such as automobiles, with more environmentally friendly propulsion means than four-wheeled vehicles with conventional internal combustion engines. A particular option for such propulsion means involves the use of electric motors. [0003] Typically, an electric propulsion motor is located on the drive shaft of the vehicle and provides torque to the drive wheels through a differential. Although it is possible to replace the internal combustion engine with such an electric drive axle, the main path for most automakers is to provide the electric axle as an auxiliary to the main internal combustion e...
