Patented Oct. 3, 1939 VEHICLE FRAIVIE Gerhard C. R. Kuiper, Cleveland, Ohio, assignor to The Midland Steel Products Company, Cleveland, Ohio, a corporation of Ohio Application February 11, 1937, Serial No. 125,227
7 Claims.
This invention relates to new and useful improvements in motor vehicle frames and has as itsprimary object, the provision of a frame having transverse cross members which is as rigid as the present type frame incorporating an X-shaped member at substantially the center thereof.
Another important object of the invention is to provide means for increasing the section modulus of certain of its component parts.
Another object of the invention is to provide a connecting member for the two side rails to take the place of the usual X-shaped member.
A further object of the invention is to provide a special form of transverse cross member having means for avoiding interference with the transmission casing and drive shaft.
Other objects and advantages of the invention will become apparent during the course of the fol lowing description.
In the accompanying drawing forming a part of the specification and wherein like numerals are employed to designate like parts throughout the several views:
Fig. l is a perspective view of the improved type of frame,
Fig. 2 is a transverse section of one of the longitudinal members thereof showing the manner of connecting one of the transverse cross members,
Fig. 3 is a similar view showing another manner of connecting another transverse cross member,
Fig. 4 is an enlarged elevation of the central portion of the third cross member, which yieldably supports the transmission,
Fig. 5 is a transverse section taken on the vertical diameter of the portion Bil of Fig. 4, and,
Fig. 6 is a section of the fourth cross member and taken on a line 6--6 of Fig. 1.
Referring now more particularly to the drawings for a detailed description of the improved frame, the numeral 6 designates a pair of longitudinally extending members or side rails of the frame, both of which are substantially identical and therefore a description of one will suflice for both. Each side rail is provided with a front kickup or vertically bent portion 1 and a rear one 8 of usually greater degree to clear the axles and lower the center of gravity of the vehicle. Between these kickups and substantially at the mid-section of each rail, there is an outwardly bowed section 9, of greater depth than the ends of the rail.
As best appreciated in Figs. 2 and 3, each side rail is hollow or tubular from one end thereof to the other and of substantially inverted T-shape with both the arms and stem of the T possessing hollow section. Each rail is formed from an inverted U-shaped stamping with a top [0 and a pair of parallel depending sides H. In previous 5 rails of this type, the tubular or box section for the rail has been provided by securing a plate to the longitudinal edges of the side walls II or to outwardly extending flanges thereof. In order to increase the tubular or hollow section over and above the usual section, the outwardly extending horizontal flange portions I2 are given an additional bend to cause the edge portions 63 of the flanges to be arranged normal to the flanges I! and parallel with the side walls I l. 15
In order to completely box in each side rail and to form it into completely closed box section, a flat plate in one piece or in sections throughout the length of the rail is secured to the edge portions l3 in any suitable manner, but preferably by welding Either the free edges of the edge portions l3 or the margins of the plates M may be provided with integral projections at intervals throughout the length of the rail for projection welding the two together. Fig. 3 shows the flat plate M as possessing integral welding projections I5 along the marginal edges. This construction forms, the flanges l2 as well as the main body portion of the side rail into hollow or tubular section and performs an important part in increasing the rigidity of the member. A pair of such rails are arranged in spaced relationship as usual and are connected in such relationship by transverse tubular cross members l6, l1, i8, i9, 2!] and 2! in such order from the front to the rear of the frame. The ends 22 of these tubular cross members are better shown in Figs. 2 and 3 as extending through apertures in both side walls I I of each side rail and welded thereto as at 23 and 24. These tubular ends may be spaced above the flanges l2 of the side rails or have their lowermost portions rest on the upper surfaces thereof to be welded thereto as at 25 and shown in Fig. 3.
The motor 26 is supported between the two for ward ends of the side rails and may be partially or wholly supported on the first and second cross members l6 and II. A transmission housing 21 is located rearwardly of the motor and is provided with an extension 28 to which the drive shaft torque tube 29 is connected. In order to space the side rails adjacent the dash portion which is in proximity to the transmission, a special form of cross member 18 is provided. This cross member as stated previously is of tubular section with its central portions 30 enlarged and provided with an enlarged central opening 3| therethrough, by suitably slitting or slotting the middle of the tube at diametrically opposite points and stamping and forming the same to enclose the extension 28 of the transmission. This extension of the transmission may be rigidly secured to the central portion of the cross member or a yieldable or resilient supporting ring 32 may be enclosed in the enlarged circular channel-shaped portion of the cross member to yieldingly engage the extension 28 of the transmission which extends therethrough,
The fourth cross member l9 which takes the place of the usual X-shaped member in the present frame, is a rather unique member in frame construction and is preferably made from a single piece of sheet metal rolled, formed and welded with a single seam into a tubular member. It has a general contour, shaped somewhat like an hourglass. The section of the entire member is substantially elliptical or oval instead of circular, with its major axis horizontal. The two ends 33 of this cross member are much enlarged over the central I restricted portion 34 and have their front and rear sides arranged in inwardlyconverging relation ship. These tapering ends of the cross member also are inclined downwardly toward the constricted center 34 so that the drive shaft tube 29 m may extend thereabove without interference, or if preferred, this cross member may be bowed upwardly and disposed above the drive shaft tube 29. The extreme ends of this cross member which extend through the two sides of each rail 9, are
/ about 12 to 18 inches or more wide and may or -may not taper on out to the extreme end, as
desired. It will be particularly noted that the cross member i9 is extremely wide where it joins with the two side rails, and from tests, has been found to render the frame substantially as strong as an X-member frame.
It is to be understood that various changes in the shape, size and relationship of parts may be resorted to without departing from the scope of g the appended claims.
