AI Technical Summary

Problems solved by technology

Particles from the locking coating can become lodged between the flanges, which causes the flanges to not be flush with each other
If the transmission flange and driveshaft flange are not flush with each other, the assembly will be out of specification and potentially out of balance causing unwanted noise, vibration and harshness problems

Abstract

A drivetrain assembly includes a transmission and a driveshaft that are joined together by a transmission flange and a driveshaft flange that has a plurality of pre-assembled bolts. The driveshaft flange defines a plurality of holes and countersink recesses and the bolts are secured to the driveshaft flange by a bolt retainer disposed in each of the countersink recesses between the transmission flange and the driveshaft flange. A method is disclosed for assembling a transmission flange and a driveshaft flange that defines a plurality of holes and countersink recesses. A bolt is assembled into each of the holes and countersink recesses and a bolt retainer is attached to each of the bolts and nested inside the countersink recesses to retain the bolts on the driveshaft flange. The bolts on the driveshaft flange are then installed into the threaded holes of the transmission flange.

Description

technical field [0001] The present disclosure relates to a method and apparatus for assembling a drive shaft to a transmission using pre-assembled fasteners. Background technique [0002] A drivetrain for a vehicle may include an internal combustion engine or an electric motor that provides torque to a propshaft through a transmission. The propshaft transmits torque to the wheels of the vehicle. The transmission and propshaft are separate components that are typically manufactured separately and assembled together with fasteners on the final assembly line. During final assembly, threaded fasteners, such as bolts, are individually assembled and secured to the transmission flange and propshaft flange. This requires the assembler responsible for these bolts on the final assembly line to start tightening the bolts by hand. Bolting the flanges together is labor intensive and time consuming for the assembler. [0003] The transmission and drive shaft are secured together by fl...
