1,240,779. Vehicle chassis. AUTOMOBILES CITROEN S.A. 10 Oct., 1969 [25 Oct., 1968], No. 49866/69. Heading B7D. [Also in Division B3] An assembly, e.g. forming part of a vehicle chassis, comprises two semi-shells 1a, 1b secured together along flanges 2a, 2b to form a first tubular member 1, a second tubular member 3 engaged in and secured to the first, two lateral partitions 6a, 6b disposed within the first member, one on each side of the second member, and secured to the first member, and a further partition 5 disposed within the first member and secured to the second member and the lateral partitions. The assembly is made as follows: tubular member 3 is passed through an outwardly flared aperture (4) (Fig. 2, not shown), in semi-shell 1a to which discs 6a, 6b have been secured one on each side of the aperture. Partition 5 is engaged in the end of member 3 by means of an annular flange 5a and is secured thereto. Member 3 is then retracted to bring opposed edges of partition 5 into abutment with flanges 2a, 2b of semi-shell 1a, the edges then being secured to these flanges. At the same time flanges 5b on partition 5 engage and are secured to inner surfaces of discs 6a, 6b, The resulting sub-assembly is then mated with semi-shell 1b of which flanges 2a, 2b are secured to corresponding flanges of semi-shell 1a, semi-shell 1b also being secured to flanges 7a, 7b of discs 6a, 6b, e.g. by welding through orifices 11 in semi-shell 1b. Spot-welding techniques may be employed in securing the component parts of the assembly together. The discs 6a, 6b may have central apertures (9) and the partition 5 may have an aperture and recesses 8. |
