The invention relates to a transmission synchronisation method and a transmission synchronisation device for at least two transmission units (TT). The synchronisation takes place in that in each case an output revolution speed (nn) of an axle drive shaft arranged in a transmission (TT) is adjusted by means of a first and second adjustment unit (ADU, ADU). The synchronisation of the first and second transmissions (TT) takes place by a result value (cal_out) of an arithmetic logic unit () being conducted to the second adjustment unit (ADU) arranged at the second transmission (T), dependent on the first transmission (T) and on the reference value (v_set) of a preselection unit ().

Fluid container for a motor vehicle, with a tank () and a retaining structure (), which is suitable for carrying the tanks (), characterized in that the retaining structure is designed in such a way that the tank () is mounted on it such that it can be displaced. The tank can be displaced in such a way that access to important components is possible without complete dismantling, and, as well as this, the installation and dismantling of the tank can be designed to be easier, faster, and therefore more economical.

The invention relates to a steering system for a utility vehicle, wherein the steering movement is transmitted to the utility vehicle wheels via a steering linkage provided on a steering unit (). The steering unit () is arranged so as to be displaceable along a guide unit () which is fixed relative to the utility vehicle. A displacing force upon the steering unit () may be provided by a hydraulic cylinder arrangement integrated into the steering unit and/or by a mechanical coupling to a steering wheel for example.

The invention relates to a groundspeed power take-off (PTO) shaft arrangement in a commercial agricultural vehicle. The groundspeed PTO shaft arrangement has a groundspeed PTO shaft device with a differential gear (). The differential gear contains an input shaft () which is coupled to a gear (). A right wheel output shaft () is coupled to an end drive () of a right wheel () and driven via the input shaft (); a left wheel output shaft () is coupled to an end drive of a left wheel and is driven via the input shaft (). Provided in this case is a first PTO shaft () which issues from the differential gear () relative to the input shaft (), is driven by the input shaft () and is coupled to the right or left wheel output shaft ().

A vehicle, in particular an agricultural tractor, is disclosed with a vehicle chassis, which is formed at least partly from two laterally spaced side members () with C-shaped profile, comprising a vertical bar () and two horizontal flanges () and containing hydraulic lines in the space between the flanges, and with a radiator sub-assembly (), fitted to the vehicle chassis, which consists of a carrier plate () fitted to the side members and several oil coolers () supported by the carrier plate. In order to improve the routing of the hydraulic lines to the oil coolers and to provide unhindered assembly and simple subsequent maintenance, it is proposed that the open sides of the C-profile of the side members () should point to the vehicle exterior, that at least one subsection () of the carrier plate () extends into the region between the side members () and that ducts (), connected to the oil coolers () are integrated into the at least one subsection () of the carrier plate () and flow into lateral ports () turned towards the vertical bars () and can be connected through recesses () in the bars () to hydraulic lines () laid between the flanges ().

Utility vehicle, in particular an agricultural tractor

A brake mechanism for a utility vehicle which can be installed around a drive shaft or inside a wheel hub. The brake has a non rotatable fixed body (), a rotatable body () rotatable relative to the fixed body (), at least one brake disc () which is non-rotatably relative to the fixed body (), and at least one rotating brake disc () which is fixed for rotation with the rotatable body (). An actuating member () can press the fixed brake disc () and the rotating brake disc () against each other and against a stop surface () on the fixed body to apply the brake. A spring means () also exerts an immobilizing force on the actuating member () to press the fixed brake disc () and the rotating brake disc () against each other to apply the brake. A brake release means () can exert a brake release force which counteracts the immobilizing force of the spring so that the actuating member () no longer presses the fixed brake disc () and the rotating brake disc () against each other, and a brake applying means () can exert a pushing force on the actuating member () in the same direction as the immobilizing force to press the fixed brake disc () and the rotating brake disc () against each other to apply the brake.

The invention relates to a utility vehicle () with a hinged cover element () which covers a fuel tank () and at least part () of an ascent region when the cover element is in a covering position. The cover element () can be pivoted from the covering position to an open position. A safeguarding element () is non-rotatably coupled to the cover element (), so that the cover element () and the safeguarding element () have the same pivot axis and are both moved to the open position simultaneously.

A radiator module for commercial motor vehicles, in particular for agricultural tractors, has a support plate fixed to the chassis and at least one coolant radiator fixed to the support plate. The radiator has a radiator block and two coolant tanks oriented at opposite ends of the block with one tank adjacent the support plate and one spaced away form the support plate. In order to increase the cooling performance of the radiator module despite keeping the installation space above the support plate constant it is proposed that the coolant tank near the plate is constructed from two mutually complementing tank parts. The first tank part is assigned to the radiator block and has an encircling flange for pressure sealed attachment of the coolant radiator on the support plate. A second tank part is assigned to the support plate. By dividing the coolant tank into two parts, one on the radiator block and one on the support plate the effective heat sink area of the coolant radiator can be substantially increased. On the one hand the enlargement is due to the fact that the flange encircling the first tank part also serves to attach the coolant radiator on the support plate and in this region an assembly gap is therefore left between these components. On the other hand the enlargement is due to the fact that by moving part of the coolant tank under the surface of the support plate, the overall height of the coolant radiator is increased accordingly.

A system operated by what is referred to as a clutch pedal, which adjusts the traction power of an infinitely variable, hydrostatic-mechanical transmission. The transmission contains at least one pump (,) and at least one motor (,), arranged in a hydraulic circuit. In order to reduce the traction power, pressure is leaked between the two sides of the motor (,) by reducing the pressure at the control parts (,) of two proportional valves (,) in respective lines bridging the motor (,). The control parts (,) of the proportional valves (,) are connected via a shift valve (,) to an intermediate valve (,), the closing force of which is reduced as the clutch pedal (,) is opened by means of a closing spring (,).

A transmission coupling assembly for absorbing axial and/or angular displacement between an internal combustion engine and a downstream gear train comprises a resilient vibration damper (3;24) secured to the flywheel (1;26). A coupling member (4;23) secured to the vibration damper is rotationally coupled to a coupling shaft (7;21) by means of interlocking splines, the splines (4a) of the coupling member being substantially straight and the splines (5a) of the coupling shaft being crowned or spherically curved. At the other end of the coupling shaft (7;21) a similar splined connection is made to the input shaft (8) of the downstream gear train. Lubrication is provided at the splined connection between the coupling shaft and the input shaft of the gear train, with a Z-cross section seal extending between the coupling shaft and the gearbox casing to prevent leakage of lubricant fluid.
