I suggest you to take a look at this tutorial :
http://gazebosim.org/tutorials?tut=set_velocity#SetVelocityInstantaneously
Maybe you will have to play with some parameters of your link like the friction to make it enable to keep some velocity.

Take a look at the surface tag which contains friction parameters.
