Abstract
A drive shaft assembly for a vehicle includes a first tubular member and a second tubular member. The second tubular member is mated to the first tubular member. The first tubular member defines a plurality of protuberances and the second tubular member includes a plurality of apertures. Each of the plurality of apertures receives one of the plurality of protuberances substantially affixing the first tubular member to the second tubular member in a circumferential orientation.
Claims18
A drive shaft assembly for a vehicle, comprising:
- a first tubular member and a second tubular member received by said first tubular member thereby defining a coaxial relationship between said tubular members, said first tubular member defining a plurality of protuberances and said second tubular member defining a plurality of apertures each having opposing sidewalls, with each of said plurality of apertures receiving one of said plurality of protuberances such that each of said protuberances abut said sidewalls of each respective said apertures and thereby affixing said first tubular member to said second tubular member in a substantially fixed circumferential orientation.
A collapsible shaft assembly for a vehicle, comprising:
- a first tubular member and a second tubular member received by said first tubular member thereby defining a coaxial relationship between said tubular members, said first tubular member defining a plurality of protuberances defining a protuberance length and said second tubular member defining a plurality of apertures having an aperture length, each of said plurality of apertures each having opposing sidewalls and receiving one of said plurality of protuberances such that each of said protuberances abut said sidewalls of each respective said apertures and thereby affixing said first tubular member to said second tubular member in a fixed circumferential orientation and said protuberance length being less than said aperture length allowing axial movement of said first tubular member relative to said second tubular member.
