A fluid distribution apparatus for an axle assembly, the fluid distribution apparatus including a cylindrical portion rotatably disposed about a bearing race. A conical portion is coupled with the cylindrical portion, and a retaining portion is coupled with the conical portion. A plurality of circumferentially spaced tubes are coupled with the retaining portion, wherein the tubes are at least partially disposed through a rotating component of a clutch.

The invention relates to a hydrodynamic transmission gear-box that contains two pump wheels, which are round flat disks, on the front peripheral part of which installed firmly are radially directed blades. The first wheel is rigidly connected to the input shaft. The second and subsequent pump wheels, each with a diameter greater than the previous one, are mounted with their own hubs onto the hubs of the preceding pump wheels with the possibility of free rotation on them. On the back side of each disk, a device is installed to block it with the next pump wheel, and the last pump wheel—with the turbine wheel. The turbine wheel is mounted on the input shaft and in the crankcase of the drive device on bearings and is connected to vehicle's reverse mechanism and running gear. Reduction in weight and size, increase of service life and performance improvement are achieved.

A hydrodynamic clutch having an input side and an output side, the rotational motions of which are coupled to one another with a hydraulic fluid. A method for determining the degree of filling of the hydrodynamic clutch with fluid including steps of periodically sensing a fluid temperature of the hydraulic fluid, determining the thermal output supplied to the clutch on the basis of the temperature, determining a lambda value on the basis of the thermal output and determining the degree of filling on the basis of the lambda value.

Provided is a fluid fan clutch with excellent cooling performance capable of effectively preventing, by very simple means, a decrease in the volume of air due to backflow of cooling fan air occurring when the fan clutch is activated. The fluid fan clutch has a structure with a fan removably fixed to a housing composed of a front-side housing component (cover) and a back-side housing component (case), wherein projecting parts for preventing backflow of fan air are arranged on the back-side housing component so as to be shifted in the circumferential direction with respect to fixing projections of the front-side housing component.
