A wheel joint. This joint provides two degrees of freedom: translation along an axis fixed in bodyA and rotation in the plane. You can use a joint limit to restrict the range of motion and a joint motor to drive the rotation or to model rotational friction. This joint is designed for vehicle suspensions.
