hey guys I am working on a project for school and I am wondering the safest possible way to connect a motor to a differential axle such that the axle is still able to carry the load and have it all balance I am having problems as to how safely and best I can connect an motor to a differential axle without using a shaft in between.

 

If you do that, you will need to be careful with the suspension load, and you shouldn’t expect perfect results in terms of reversing, brush timing, etc. You need to see if the ratio can produce something that has a realistic potential, otherwise, you can’t do it simply just like that. Almost all modern electric cars use a torque converter, so I’d suggest that you incorporate one and have a peace of mind. You can find some online for as low as $50, and depending on the size and type you may go up to $200.

 

Hello Anthonycaspian!

From the point of view of efficiency, it is not reasonable to connect the electric motor to the rear axle, it is better to connect the electric motor directly to each wheel.

If you want to do this, you need an electric motor more than the one in your image =)

You also need a gearbox because without a gearbox you just need a huge electric motor.

In order for the electric motor not to burn you will also need a soft start device.

Yes, the torque converter will be a great solution but it is also quite possible to get away with an electronic soft-start device and an electromagnetic clutch.

 

Hello for the prototype that I am doing now it is not possible to get the funds to provide each electric motor to each wheels. However would it be possibly to use a lovejoy coupling for the electric motor directly to the axle
