An autonomous tilting three-wheeled vehicle comprises a pair of front wheels coupled to a tiltable chassis by a mechanical linkage, such that the pair of wheels and the chassis are configured to tilt in unison with respect to a roll axis of the chassis. An electronic controller of the autonomous vehicle controls a tilt actuator to selectively tilt the chassis. Optionally, a steering actuator is coupled to the front wheels and controlled by the electronic controller to selectively steer the wheels. A sensor configured to measure orientation-dependent information may be coupled to the chassis by a gimbal configured to compensate for vehicle tilt. In some examples, the autonomous vehicle comprises an autonomous delivery robot.

Suspension assembly including a body associable to the chassis of the tilting vehicle and two junction devices opposite with respect to the body; the junction devices being articulated to the body by means of connecting elements, wherein each junction device includes a first structural junction portion rotationally coupled in a first coupling site to a first connecting element and a second structural joint portion rotationally coupled in a second coupling site to a second connecting element; and wherein the suspension assembly further includes elasto-damping elements associated with the hinge devices and adapted to damp the stresses transmitted by the wheels; and wherein each hinge device includes a dynamic junction portion rotationally coupled to a elasto-damping element in a dynamic junction coupling site; and wherein the junction device rigidly determines the relative positioning and spatial orientation of the first structural joint portion, the second structural joint portion and the dynamic joint portion; ; the suspension assembly further having a rocker arm element associated in a titling manner to the body and to the elasto-damping elements.

An air intake system for a vehicle has a conduit having an internal wall forming an air passage. A deflector is disposed within the air passage. A restricting structure is disposed within the air passage between the deflector and a conduit outlet. The restricting structure defines at least in part an opening substantially laterally aligned with the deflector. The restricting structure has a lateral wall disposed downstream of the deflector and extending within the air passage. The lateral wall has a front surface generally facing a conduit inlet, and a plurality of surface-increasing features provided on the front surface. Each of the surface-increasing features has a length of at least 1 mm measured from the front surface in a direction normal thereto. An air intake system having a collector connected to the deflector and positioned to collect at least some moisture from air flowing past the deflector is also described.

Vehicles are disclosed which have a lower center of gravity than existing all-terrain, amphibious, and unmanned ground vehicles due to the location of propulsion units and other vehicle components inside the wheels of the vehicle. The vehicles can climb over large obstacles yet are also able to corner at high speeds. The vehicles can be configured for direct manual operation or operation by remote control, and can also be configured for a wide variety of missions.

A self-balancing tilting vehicle comprising a rear frame section having two drive wheels and a front frame section having at least one front wheel, connected to the rear frame section such as to be tiltable about a tilt axis that extends in a length direction, the front frame section carrying a driver seat, the rear frame section comprising an electric propulsion drive for rotating the drive wheels, an electric tilting drive for tilting the front frame section about the tilting axis and a power generating unit, the front wheel being rotatable about a steering axis that extends transversely to the tilt axis, characterised in that the drive unit of the tilting vehicle is cut off well before the tilting drive.

A motor vehicle with at least a first driving wheel tilting with respect to a first rotation axis transverse to the motor vehicle and a second driving wheel tilting with respect to a second rotation axis transverse to the motor vehicle has a power source for power generation and a transmission for power transmission to the first tilting driving wheel and second tilting driving wheel.

A three wheeled vehicle is disclosed having a radiator positioned forward of an engine and coupled to the engine for cooling the engine. A front radiator shroud is positioned over the radiator on a front side and a rear radiator shroud is positioned over the radiator on a rear side. The rear radiator shroud has a rear baffle plate directing air downwardly and under the operator's compartment.

A reverse transmission system for a vehicle for engaging a reverse action on a normally forward action only engine transmission having a longitudinal orientation driveshaft output, the reverse transmission system comprising a gear rotatably connected to the longitudinal orientation driveshaft output of a normally forward action only engine transmission output; a shaft rotatably connected to the gear for transmitting power from the normally forward action only engine transmission output to the shaft; a chain sprocket connected to a chain drive and to the shaft for providing a transverse orientation output to the chain drive to change the direction of rotation of the driveshaft output, thereby for engaging the vehicle in the reverse action; and a reverse fork configured to actuate a reverse dog configured to slide upon the shaft to reversibly engage a reverse gear engaged to a first gear of the engine transmission.
