A passenger vehicle provided with a steering handle (15) and configured such that an attitude angle of the driver seat surface (14a) relative to a horizontal reference plane is changeable, so that a first attitude changing operation switch (25) and a second attitude changing operation switch (26) for changing the attitude angle are disposed in such positions as to be operable with a thumb of the driver of the vehicle from a steering handle grip (18) of the steering handle (15).

A wheel suspension system for a vehicle having a chassis, comprising an opposing pair of wheel uprights having a plurality of pickup points located thereon, an opposing pair of main axis arms, an opposing pair of integrated axis arms, an internal cambering system comprising opposing pairs of camber links and radius rods, and an internal springing system comprising a single spring shock and an opposing pair of spring levers having tension links attached thereon. An internal roll-controlling weight transfer system comprising an opposing pair of weight transfer links having attached springing shocks may also be included.

A suspension for a motor vehicle includes at least one internally hollow suspension arm, so as to define at least one inner cavity, and is characterized by comprising at least one duct extending along the inner cavity between an input hole of the suspension arm and an output hole of the suspension arm, the duct being designed to allow a fluid flow or an electric wiring to go from the input hole to the output hole through the inner cavity.

A suspension structure of a utility vehicle includes a frame, a wheel, and a trailing arm including an arm extending anteroposteriorly and supported by the frame, a knuckle rotatably supporting the wheel, and a rotary shaft configured to angularly displace the knuckle in a vehicle width direction with respect to the arm.

A vehicle includes an aerodynamic mechanism for a vehicle including a body and a wheel. The aerodynamic mechanism includes a wing and a coupling assembly. The wing is configured to be arranged to intersect and airflow such that the airflow circulates about the wing and generates downforce. The coupling assembly is operatively connected to the wing and configured to be operatively connected to the body. The coupling assembly is configured to be selectively coupled to the wheel such that downforce generated by the wing is transmitted through the coupling assembly, directly to the wheel. The coupling assembly is configured to be selectively decoupled from the wheel such that downforce generated by the wing is transmitted through the coupling assembly, directly to the body.

A system is configured to control aerodynamics of a vehicle. The vehicle includes a vehicle body having a front end facing an ambient airflow when the vehicle is in motion relative to a road surface. The system includes an adjustable aerodynamic-aid element mounted to the vehicle body. The system also includes a mechanism configured to vary a position of the adjustable aerodynamic-aid element relative to the vehicle body and thereby control movement of the airflow. The system additionally includes a sensor configured to detect a height of the vehicle body relative to a predetermined reference frame and a controller configured to receive a signal from the sensor indicative of the detected vehicle body height. The controller is also configured to determine a ride-height of the vehicle using the detected vehicle body height and to regulate the mechanism in response to the determined ride-height to control aerodynamics of the vehicle.
