DRIVE SHAFT OF TRANSPORT VEHICLE Russian patent published in 2015 - IPC F16D3/26 F16C11/06 

FIELD: machine building.

SUBSTANCE: drive shaft contains kinematically linked with shaft ends hinges of equal rotational speeds with bellows. Each bellows is connected with the hinge body and shaft by installations sections of larger and smaller diameters. The drive shaft contains female thrust collars at each shaft end upstream the control bushing of each hinge, which cavities are sealed outside. At each shaft end upstream the female support collar a seat section is with the diameter exceeding internal diameter of the hinge control bushing; on the seat section the damping wheel is installed, its width exceeds width of the seat section, and outside diameter is at least equal to outside diameter of the female thrust collar. Cavity of each hinge is sealed outside by means of the plastic plug made as rotation body, tightly installed by the installation part in the hinge cavity and having bottom part consisting of round central part that is located at right angle to the axis of rotation of the plug, and ring section inclined relatively to this axis.

EFFECT: exclusion of possibility in the drive shaft hinges their metal control bushing impact against female thrust collard of the metal shaft, thus excluding damage of the collided parts and noise.
