Drive System for All-Terrain Vehicle (ATV)

A drive system in an electrically driven all-terrain vehicle comprising:

• an electric motor rotationally connected to a gearbox;
• a drive system comprising four propulsion assemblies;
• a first differential rotationally connected to two of the four propulsion assemblies and a second differential rotationally connected to the other two of the four propulsion assemblies;
• wherein the first differential is rotationally connected to the gearbox;
• and a drive shaft rotationally connected to the gearbox and extending therefrom to connect to the second differential.

A drive system for an electrically drive all-terrain vehicle comprising:

• an electric motor;
• a battery;
• a gearbox;
• a first differential;
• a second differential;
• a first pair of wheel and tire assemblies and a second pair of wheel and tire assemblies;
• and
• a drive shaft;
• wherein the electric motor is electrically connected to the battery, the electric motor including a motor shaft that extends outward from the electric motor and is at least partially received in the gearbox and coupled thereto to rotationally connect the electric motor to the gearbox;
• the gearbox is rotationally coupled to the first differential on one side and the drive shaft on an opposite side;
• wherein the drive shaft extends from the gearbox to the second differential to rotationally couple the gearbox to the second differential;
• the first differential being rotationally coupled to the first pair of wheel and tire assemblies by a first pair of axles extending outward therefrom;
• and
• the second differential being rotationally coupled to the second pair of wheel and tire assemblies by a second pair of axles extending outward therefrom;
• the drive assembly further comprising a chassis supporting the electric motor, the gearbox and the first differential in a rearward end thereof;
• the chassis supporting the second differential at a forward end thereof and the drive shaft extending forward from the gearbox to the forward end;
• the chassis including a first suspension subframe at the rearward end, wherein the electric motor, gearbox and first differential are mounted on the chassis above the first suspension subframe;
• the chassis further includes a second suspension subframe at a forward end, wherein the second differential is mounted above the second suspension subframe;
• and wherein the chassis includes a saddle portion at the rearward end that extends forward of the gearbox toward the forward end and a steering assembly spaced forward from the saddle portion, and wherein the chassis defines a cavity between the saddle portion and the steering assembly that opens upwardly, wherein the battery is removably mounted within the cavity and accessible through the opening.
