A vehicle system is provided. The vehicle system includes a vehicle chassis with a plurality of elongated tubular members. The tubular members are structured to be configured in a configuration selected from the group consisting of a coup, a convertible, a truck, a transport vehicle, or a bus.

An automotive suspension for a sports car comprising a lower oscillating arm and a shock absorber having a relative end connected with a first intermediate part of the lower oscillating arm by means of a connecting rod having a first end hinged with said end of the shock absorber and a relative second end, opposite to the first end, hinged with said first intermediate part, locking means for locking said connecting rod in a stable position ranging between two extreme positions wherein said first end of the connecting rod is in a position close to or distal relative to the frame of the car.

An apparatus and methods are provided for a modular front drivetrain comprising a single assembly that may be installed onto and removed from a vehicle. The modular front drivetrain comprises a modular chassis supporting a transaxle, a front differential, and a steering gear for operating front wheels of the vehicle. The transaxle, the front differential and drive axles convey torque from an engine onboard the vehicle to the front wheels. A spindle assembly is coupled with each front wheel of the vehicle and pivotally joined with the modular chassis by way of a front suspension system. Steering rods coupled with the spindle assemblies horizontally rotate the front wheels according to operation of a steering wheel onboard the vehicle. The modular front drivetrain advantageously facilitates replacing an entire drivetrain and suspension assembly quickly and easily in the event of a part failure during racing applications.

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 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.

Method to control active shock absorbers of a road vehicle. Each active shock absorber is part of a suspension connecting a frame to a hub of a wheel and is provided with an actuator. The control method comprises the steps of: determining a longitudinal acceleration and a transverse acceleration of the road vehicle; establishing a desired lowering of a centre of gravity of the road vehicle depending on the longitudinal acceleration and on the transverse acceleration; and controlling the actuator of each active shock absorber so as to obtain the desired lowering of the centre of gravity.

A modular electronic damping control system is described and includes a damping component located at a vehicle suspension location. The modular electronic damping control system also includes a control system configured to control the damping component, and determine the type of damping component present. Also, the control system is configured to automatically tune a vehicle's suspension based on the type of damping component present, and automatically monitor the damping component and determine when a change has been made to the damping component so that the control system can then automatically re-tune the vehicle's suspension based on the change to the damping component.

A method for adjusting one or more vehicle dynamics systems of a vehicle, the vehicle comprising a road wheel and at least one vehicle sensor configured to provide vehicle condition data, the road wheel comprising a tyre sensor configured to output tyre operation data, the method comprising: receiving tyre operation data from the tyre sensor; receiving vehicle condition data from at least one vehicle sensor; calculating one or more vehicle dynamics parameters based on the vehicle condition data and the tyre operation data; and adjusting one or more vehicle dynamics systems in response to the calculated one or more vehicle dynamics parameters.

A rear portal trailing arm assembly for a vehicle rear suspension that includes a CV joint hub for coupling with a transaxle and a wheel hub for coupling with a rear wheel. A gear transfer case extends rearward from the CV joint hub to an axle case and functions similarly to a rear trailing arm. Forward mounts facilitate coupling the gear transfer case to the chassis such that the trailing arm assembly pivots vertically with respect to the chassis. A rearward mount facilitates coupling a strut with the gear transfer case to control the vertical motion of the rear wheel. Multiple gear assemblies are meshed within the gear transfer case. An axle is coupled with the meshed gear assemblies and housed within the axle case, such that torque applied to the CV joint hub is communicated to the wheel hub.
