摘要： The present invention relates to a computer system (600) comprising processing circuitry (602) configured to handle wheel slip a vehicle (1) is provided. The vehicle (1) comprises a first axle (10). The first axle (10) comprises at least two wheels (12). Each of the at least two wheels of the first axle (12) is drivable by at least two hydraulic motors (11). The processing circuitry (602) is configured to obtain a slip condition of the vehicle (1). The processing circuitry (602) is configured to, based on the obtained slip condition, trigger an adjustment of pressure and/or flow to be supplied to at least one of the at least two hydraulic motors (11) in the vehicle (1). Triggering the adjustment comprises triggering an adjustment of pressure and/or flow between at least two hydraulic motors (11), and/or triggering adjustment of pressure and/or flow supplied by a source (30). The invention further relates to a corresponding method, vehicle, computer program product and computer-readable storage medium.

摘要： A travelling frame of a travelling device positioned between a center frame and a travelling motor attachment portion includes an upper plate extended toward the center side of the vehicle to form an extended portion. A long hole into which travelling motor hydraulic piping is inserted is formed in the upper plate along the extended portion. The travelling motor hydraulic piping extends from a lead-out hole opened in an end plate of the center frame, through the long hole of the upper plate and a long hole opened in an end plate, and inserted into the travelling motor attachment portion.

摘要： A wheeled work vehicle (1) comprises a forward chassis part (4) and a rearward chassis part (5) pivotally connected about a substantially vertically extending primary pivot axis (7) for steering thereof. A pair of forward ground engaging wheels (29) are carried on a forward suspension unit (32), and a pair of rearward ground engaging wheels (30) are carried on a rearward suspension unit (33). The forward suspension unit (32) is pivotally connected to the forward chassis part (4) by a pair of main forward transverse pivot shafts (63) pivotally coupled to the forward chassis part (4) by corresponding main forward pivot mountings (65). The main forward transverse pivot shafts (63) defines a main forward transverse pivot axis (59) about which the forward suspension unit (32) is pivotal relative to the forward chassis part (4). The forward suspension unit (32) comprises a pair of spaced apart trailing arms (35) which are joined by a torsion shaft (68) of tubular steel, which is rigidly connected to the trailing arms (35). The torsion shaft (68) defines a torsional axis (70), and permits limited upward and downward pivotal type torsional deflection of the trailing arms (35) relative to each other. The rearward suspension unit (33) is substantially similar to the forward suspension unit (32) and is coupled to the rearward chassis part (5) about a pair of main rearward transverse pivot shafts (87) in a similar manner as the forward suspension unit (32) is coupled to the forward chassis part (4).

摘要： The invention concerns an axial bearing between a first part and a second part that presses with an axial load against the first part and can rotate around a rotation axis relative to the first part comprising a circular or arc-shaped ridge on the first part centered around the rotation axis, a pressure source for providing pressurized hydraulic fluid on a first side of the circular or arc-shaped ridge, an adjustable gap between the circular or arc shaped ridge and a bearing surface on the second part, wherein the pressurized hydraulic fluid flows through the adjustable gap to a second side of the circular or arc-shaped ridge. In accordance with the invention the circular or arc-shaped ridge and/or the bearing surface comprise(s) a ridge chamber for locally creating a larger adjustable gap between the circular or arc-shaped ridge and the bearing surface.

摘要： A riding lawnmower vehicle includes two main drive wheels, at least one caster wheel, an electric traction motor, an internal combustion engine, a generator driven by the internal combustion engine, and a lawnmower. The electric energy generated by the generator can be supplied directly or via an electric accumulator to the electric traction motor. The main drive wheels are independently driven by the electric traction motor, which can operate as a traction power source. When viewed from one end to the other end in the width direction of the vehicle, the internal combustion engine and a secondary battery operable as the electric accumulator overlap each other, and the main drive wheels overlap at least a part of at least one of the internal combustion engine, the generator, the secondary battery, a fuel cell, a capacitor, an inverter, a cooling device, a mower driving motor, and a grass-collecting duct.

摘要： An agricultural vehicle and method of controlling the same are provided, the vehicle having a motive power unit providing a driving torque to at least one driven wheel and having at least one tire or track frictionally coupled with the periphery of the driven wheel. A vehicle operating parameter is controlled in dependence on the driving torque and a slippage characteristic relating the respective driving torque at which the frictional coupling between driven wheel and tire or track begins to slip for a range of vehicle operating parameter values. The operating parameter is suitably a tire pressure or track tension, and the control may involve reducing driving torque or increasing pressure/tension to prevent slipping.
