How can i apply force to local space of wheel?
You can press a/d for movement left/right.
and how can i limit rotation for ratate just around x axis?
You can use 6 degrees of freedom constraints.

Here is an example playground:

Thanks.But how to apply force in local space instead of world space?
For local space you can call TransformNode.getDirection
or TransformNode.getDirectionToRef
.
You will want to call it on a mesh that isn’t spinning around like the wheel does, though, so you need to connect the wheel to a stable “chassis” with a 6 degrees of freedom constraint, like in this playground:
