Member Function Documentation

◆ Construct()

void chrono::vehicle::jeep::Cherokee_Wheel::Construct	(	std::shared_ptr< ChChassis >	chassis,
		std::shared_ptr< ChSpindle >	spindle,
		VehicleSide	side,
		double	offset
	)

overridevirtual

Construct the concrete wheel subsystem by associating it to an existing spindle of a suspension subsystem.

The optional 'offset' argument allows models with double wheels(tires). The default value offset=0 corresponds to an axle with a single tire. A positive offset corresponds to an "outer" wheel, while a negative offset corresponds to an "inner" wheel. The wheel mass and inertia are used to increment those of the associated spindle body.

Parameters

chassis	chassis vehicle (may be null)
spindle	associated suspension spindle
side	wheel mounted on left/right side
offset	offset from associated spindle center

Reimplemented from chrono::vehicle::ChWheel.
