A fluid cooled cylinder liner for mounting in a cylinder of an internal combustion engine is provided. The fluid cooled cylinder liner includes a collar and a seal element. The collar has an outer circumferential surface dimensioned with respect to the inner circumference of the cylinder so as to be in substantially fluid sealing contact therewith, an annular cooling fluid channel formed radially inwardly of the outer circumferential surface, and a radial bore extending radially from the fluid channel through the outer circumferential surface and having one end communicated with the fluid channel and an opposite end communicated with a branch bore of the crankcase of the engine. The seal element substantially seals the interface between the branch bore of the crankcase and the radial bore of the collar of the cylinder liner against the leakage of cooling fluid.

A drive unit for a motor vehicle including an internal combustion engine, a transmission and a hydrodynamic retarder. The retarder includes both a rotor and a stator wherein the rotor is mounted on the engine crankshaft or crankshaft journal and the stator is disposed between the crankcase and rotor.

Drive unit with internal combustion engine and hydrodynamic retarder

The present invention involves a drive unit, specifically a drive unit for a motor vehicle having an internal combustion engine, a cooling system with fan and a hydrodynamic retarder with a stator, rotor and housing. The retarder is located within a space bounded on one side by the front of the crankcase, on a second side by the fan shaft which runs parallel to the engine shaft, and on a third side by the rear edge of the fan wheel. Viewed from the front, the retarder is substantially located within the fly circle of the fan wheel whereby the air flow generated by the fan wheel removes heat, generated by braking actions, from the housing of the retarder.

A drive unit comprising an engine, a transmission, a hydrodynamic retarder comprised of a rotor impeller wheel, a stator impeller wheel and a retarder housing enclosing both. A coolant circuit having coolant also serves as a working fluid of the retarder, and a pump impeller wheel is arranged coaxially with the rotor impeller wheel of the retarder which is used to circulate the coolant. Given this configuration, the space needed by the units which perform the pumping and braking functions of the drive unit are minimized while the efficiency of the pumping and braking functions are maximized.

Drive unit with engine and retarder

A drive unit, notably for a motor vehicle with an internal combustion engine and a transmission. The drive unit has two hydrodynamic retarders, each featuring a rotor and a stator. A primary retarder precedes the transmission in the power train and a secondary retarder follows the transmission in the power train.

The present invention involves a drive unit, specifically a drive unit for a motor vehicle having an internal combustion engine, a cooling system with fan, a transmission and a hydrodynamic retarder with a stator, rotor and housing. The retarder rotor is mounted on either the engine shaft or a crankshaft journal which is coaxial with the engine shaft. The retarder is located within a space bounded on one side by the front of the crankcase, on a second side by the fan shaft which runs parallel to the engine shaft, and on a third side by the rear edge of the fan wheel. Viewed from the front, the retarder is substantially located within the fly circle of the fan wheel whereby the air flow generated by the fan wheel removes heat, generated by braking actions, from the housing of the retarder.

The retarder housing comprises a bell and a cover body. The cover body defines a chamber having two outlets and an inlet. The chamber being in fluid communication with the working space of the retarder.

Mounted to the crankcase and located between the crankcase, fan and retarder is an intermediate body which supports the retarder housing and stator, the fan, a regulator and switch for a generator, an idler pulley for a drive belt for auxiliary units and an air conditioning compressor.

A central swivel joint for optimizing ground adaptation of front machinery of farm tractors has a central beam and a support beam that are rigidly connected to one another to form a constructive unitary part. A support is provided which has a friction bearing in which the support beam is supported. The friction bearing includes a floating bearing and a stationary bearing and is connected to the lubrication system of the motor of the farm tractor for lubrication purposes. The central beam can be in the form of a conventional square beam. Furthermore, the stationary bearing for receiving the axial forces that are exerted onto the central beam is freely accessible as long as the support has not been connected to the oil pan.

A bearing for compensating masses for compensation of forces due to inertia as well as moments of inertia is in the form of a constructive unit made of the compensating masses and the support, whereby the outer mantle surface of the compensating masses provide the support surface. Furthermore, the compensating masses and the gear wheel comprise a unit whereby the exact angular coordination of crank shaft and compensating mass is ensured. The bearing arrangement results in a secondary mass compensation.
