Abstract
A metallic connector (48) secures the terminal end (50) of a first metallic tubular member (28) to an intermediate portion (52) of a second metallic tubular member (30). The connector (48) includes an end connection portion (54) having an opening (56) that receives the terminal end (50) of the first tubular member (28) and also includes a saddle portion (58) that extends from the end connection portion and receives the intermediate portion (52) of the second tubular member (30). Opposite ends (60) of the saddle portion (58) each includes a pair of spaced clamp attachers (62) for securing a clamp to permit the assembly by a connection (64) that includes a filler alloy (66) that is preferably a brazing material. The first and second tubular members (28,30) as well as the connector (48) are preferably made from stainless steel.
Claims12
In a vehicle body space frame, the invention comprising:
- a first metallic tubular member having a terminal end;
- a second metallic tubular member having an intermediate portion that is located adjacent the terminal end of the first tubular member in a transversely extending relationship;
- and
- a metallic connector including an end connection portion having an opening that receives the terminal end of the first tubular member in a secured relationship, the connector also including a saddle portion that extends from the end connection portion and receives the intermediate portion of the second tubular member, the saddle portion having opposite ends each of which includes a pair of spaced clamp attachers for use in clamping the saddle portion against the intermediate portion of the second tubular member for assembly, and a connection including a filler alloy of a brazing material that forms an intermetallic alloy with both the saddle portion of the connector and the intermediate portion of the second tubular member to provide securement thereof to each other.
In a vehicle body space frame, the invention comprising:
- a first tubular member made of stainless steel with a round cross section and having a terminal end;
- a second tubular member made of stainless steel with a round cross section and having an intermediate portion that is located adjacent the terminal end of the first tubular member in a transversely extending relationship;
- each of the round tubular members having a wall thickness t and having a diameter D that is at least 40 times its wall thickness t;
- and
- a connector made of stainless steel and including an end connection portion having an opening that receives the terminal end of the first tubular member, a weld that fuses the end connection portion of the connector to the terminal end of the first tubular member in a secured relationship, the connector also including a saddle portion that extends from the end connection portion and receives the intermediate portion of the second tubular member, the saddle portion having opposite ends each of which includes a pair of spaced clamp attachers that include projections extending away from the end connection portion, each projection having a hole for use in clamping the saddle portion against the intermediate portion of the second tubular member for assembly, and a connection including a filler alloy of a brazing material that forms an intermetallic alloy with both the saddle portion of the connector and the intermediate portion of the second tubular member.
In a vehicle body space frame, the invention comprising:
