Document Type and Number:
WIPO Patent Application WO/2010/058971
Kind Code:
A3
Abstract:
The present invention relates to a coupling for a propeller shaft of a rear-wheel drive vehicle to couple a transmission drive shaft of a power plant (engine and transmission) with a propeller shaft or the propeller shaft with a rear axle. The present invention comprises a plurality of pipes which are arranged at regular intervals in a circumferential direction, a middle cord which is wound around the middle of each pair of pipes, a pair of top and bottom cords which are wound above and below the middle cord continuously to cross each other, collar bushes which are attached to the top and bottom of the pipes, and rubber which covers the pipes, the collar bushes, the middle cord, and the top and bottom cords entirely. At the middle of the pipe exterior, an insert bush is attached separate from the top and bottom collar bushes. The insert bush has a winding groove in which the middle cord is wound and isolating projections which are formed on both sides of the winding groove to isolate the middle, top and bottom cords not to contact one another. A pipe joint of certain thickness is connected to one side between the isolating projections so that the insert bush has a U-shaped cross section. Therefore, efficiency in assembly and production and endurance are enhanced.
