Ideal displacement source not found in simscape.

I want to use simscape to simulate the automobile damping system driving on a sinusoidal uneven road, so I need to add a source of displacement. but why is there an ideal velocity source in the component library instead of an ideal displacement source? how can we solve it?.

Version.

Matlab r2014a.

The document has been attached.

By the way, is the component block diagram of the high version of matlab simplified?
