ABSTRACT:
An apparatus for dynamically balancing a combined assembly of a drive shaft and axle input shaft for use in a vehicle drive train system. The apparatus includes a drive head adapted to be connected to one end of the drive shaft and a support head for supporting the axle. The support head includes a cradle plate extending upwardly from a base plate mounted on the apparatus. The cradle plate has an arcuate recess formed in the upper surface thereof which is adapted to receive and support a housing of the axle. A pair of support arms are also secured to the base plate, extending upwardly and outwardly therefrom. The support arms are adapted to be secured outwardly extending portions of the housing of the axle. The apparatus further includes first and second intermediate heads which are adapted to engage and support other portions of the drive train system. Sensors are provided on each of the heads for generating electrical signals which are representative of the amount of vibrations induced when the components of the drive train system are rotatably driven by the drive head. As a result, the combined assembly of the drive shaft and the axle input shaft can be dynamically balanced for use in the vehicle.
