Need help modifying rotation(tilt)/spin

The graphs represent the back view of a vehicle(the capsule like shape) - A monowheel. In the blueprint the “capsule” is this vehicle static mesh.
The first graph is about the forward and backward movements it should spin as shown in the desired output but it spins as shown in current output
The second graph is about the left and right tilt, it should only tilt till a particular angle (for example 25 degrees on both sides) but it’s just spinning 360 degrees(till the key is released)

I’m sorry if you didn’t understand I’m not good at explaining stuff so I just designed those graphs.
If you didn’t understand, it should move like a controllable single wheel you know a bike or something but with a single wheel and you are sitting inside that wheel.

If you still didn’t understand let me know I’ll make an animation in blender and send. But I really need help here.

Thank you.
