Member Function Documentation

virtual const ChVector& chrono::vehicle::TrackShoeDoublePin::GetPadBoxDimensions ( ) const
overridevirtual

Return dimensions and locations of the contact boxes for the shoe and guiding pin.

Note that this is for contact with wheels, idler, and ground only. This contact geometry does not affect contact with the sprocket.

Implements chrono::vehicle::ChTrackShoeDoublePin.

virtual GuidePinType chrono::vehicle::TrackShoeDoublePin::GetType ( ) const
finaloverridevirtual

Return the type of track shoe (guiding pin).

A derived class must specify the type of track shoe (which must be consistent with the idler and road wheels in the containing track assembly.

Implements chrono::vehicle::ChTrackShoe.
