Abstract: A rotary seal arrangement has a rotatable component (2) supported within a machine component (3), the machine component (3) forming a housing structure for a sealing means (23) which acts to seal off a high-pressure area (10) between the components (2,3) to allow the passage of high pressure fluid therebetween. The seal arrangement includes a holding element (30) for mounting in the machine component (3) to support spaced sealing members (23) therein to define said high pressure area (10) therebetween. The arrangement is particularly suitable for use where the rotatable component (2) is formed as a rotatable shaft and the holding element (30) and sealing members (23) are arranged around the shaft such as, for example, in a vehicle tyre pressure changing system for use on an agricultural tractor.

Abstract: The invention relates to a transmission synchronisation method and a transmission synchronisation device for at least two transmission units (T1, T2). The synchronisation takes place in that in each case an output revolution speed (n1, n2) of an axle drive shaft arranged in a transmission (T1, T2) is adjusted by means of a first and second adjustment unit (ADU1, ADU2). The synchronisation of the first and second transmissions (T1, T2) takes place by a result value (cal_out) of an arithmetic logic unit (140) being conducted to the second adjustment unit (ADU2) arranged at the second transmission (T2), dependent on the first transmission (T1) and on the reference value (v_set) of a preselection unit (100).

Abstract: 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.
