A vehicle comprising at least a first wheel (6) mounted in a first side area of the vehicle and a second wheel (6′) mounted in a second side area of the vehicle is disclosed. The vehicle comprises a track device (8) configured to be brought into engagement with the ground (10). The vehicle comprises a control member (32) configured to adjust the pressure with which the track device engages the ground, wherein the pressure is determined on the basis of measurements performed by one or more detection members configured to detect one or more variable parameters of the vehicle or external information received by the vehicle.

A self-propelled machine for agriculture forms an agricultural gantry system. The machine has a support structure for receiving attachment devices, at least one drive unit with a control module, a support structure forming an agricultural gantry system and a plurality of ground supports for moving the support structure. The agricultural gantry system is convertible from a road orientation defining a driving width (FB) to a working orientation having a substantially larger working width (AB).

An agricultural vehicle combination including an agricultural tractor, which is operated using a main drive unit, and an ancillary drive unit, which is attached removably to the agricultural tractor by a three-point hitch, and which has an auxiliary axle that can be driven by an ancillary unit including at least one of a combustion engine and an electric motor.

A work vehicle includes: a body; left and right front wheels provided for the body; and left and right rear crawler units provided for the body. The rear crawler units each include: a drive wheel provided for a rear axle of the work vehicle; a front idler wheel forward of the drive wheel; a rear idler wheel backward of the drive wheel; a plurality of roller wheels between the front idler wheel and the rear idler wheel; a crawler belt wound around the drive wheel, the front idler wheel, the rear idler wheel, and the plurality of roller wheels; a track frame swingable about a swing shaft that extends in a left-right direction of the body and holding the front idler wheel, the rear idler wheel, and the plurality of roller wheels; and a position change mechanism configured to move the swing shaft in a front-back direction of the body.

A track assembly mounted to a rotating wheel drive of a vehicle that includes a frame with inboard and outboard frame members having a center gap between them. A bearing housing is mounted to the outboard frame member. A hub adaptor has a peripheral wall forming a hollow interior that receives the wheel drive. Separate annular flanges are connected to and extend away from inner and outer surfaces of the peripheral wall and connect to the wheel drive and a sprocket surrounding the hub adaptor. As the hub adaptor rotates within the bearing housing, the sprocket rotates within the center gap of the frame. Idler are rotatably connected to opposed ends of the frame. An endless track is routed over the sprocket and around the idlers. The endless track engages with and is driven by rotation of the sprocket in order to circulate the track about the frame in a generally triangular path.

The present disclosure relates to a wheel apparatus that includes a rim module coupleable to an axle and a solid tire module that extends from the rim module. The solid tire module includes a plurality of tread teeth that form a peripheral edge. The peripheral edge forms at least a portion of a tire profile. Each tread tooth of the plurality of tread teeth has a spatial specification that includes a circumferential width, a radial height, an edge shape, and a circumferential gap width. The spatial specifications of the plurality of tread teeth are non-uniform. In one embodiment, the solid tire module has a non-circular rotational trace. In another embodiment, at least a circumferential region of the peripheral edge comprises a sequence of tread teeth having sequentially increasing radial height.

An auxiliary track device for movement of a vehicle. The auxiliary track device may enhance traction and/or floatation of the vehicle, such as, for example, by being installable on the vehicle to convert the vehicle into a tracked one and/or by being deployable to engage the ground in certain situations, including where additional traction and/or floatation may be desirable based on an environment of the vehicle such as one or more characteristics of the ground (e.g., a compliance, such as a softness or hardness, a slipperiness, a soil compatibility, and/or a profile of the ground), a state of the vehicle (e.g., a speed of the vehicle, loading carried by the vehicle, etc.), a user's preferences (e.g., ride quality, etc.), and/or any other suitable factor. The auxiliary track device may be used only for traction and/or floatation of the vehicle or may be part of an implement to perform work with the vehicle.

A self-propelled machine for agriculture forms an agricultural gantry system. The machine has a support structure for receiving attachment devices, at least one drive unit with a control module, a support structure forming an agricultural gantry system and a plurality of ground supports for moving the support structure. The agricultural gantry system is convertible from a road orientation defining a driving width (FB) to a working orientation having a substantially larger working width (AB).

The present invention generally relates to vehicle and machinery in agriculture, construction, forestry, mining and powersport. It further generally relates to track systems and traction assemblies used with such vehicles. The track system comprises a drive wheel and a plurality of idler wheels mounted on a support frame. At least one of the plurality of wheels is operatively mounted on the support frame via a damping system adapted to provide a damping value dynamically varying as a function of the load applied. Track systems do not benefit from the damping provided by the layer of air within the tires. The disclosed damping system has the objective to overcome one this drawback by providing a smooth ride for tracked vehicles. The damping system comprises a cylinder fluidly connected to a reservoir. Damping ratio is varied by varying a flow circulating area between the cylinder and the reservoir.

The autonomous electric tractor is completely operated by battery and remote programming using artificial intelligence and soil sensors. The electric track has an in-track electric motor to drive a rear drivetrain sprocket to provide movement to the autonomous electric tractor. The electric tracks are slip proof and tilt proof. The mudguards protect them heavy soil contamination. The autonomous electric tractor is controlled by a cloud based remote tractor management system. Apart from 3D cameras and sensors, global positioning system and client need based data is used for utilizing the tractor for farming operations.
