Abstract:
The invention relates to a conical central pillar assembly for the bodywork of a passenger car, especially a bodywork having a space-frame bearing structure constructed from extruded light metal section bearers and cast light metal joining elements. According to the invention, the central pillar assembly includes a substantially plate-like base section wall having a multi-layer, multi-chamber extruded section disposed thereon. The section chambers in the outermost layers are selectively cut at various heights in step wise fashion in order to produce a desired conical cross section with a wide base portion and narrow top portion. Additional cuts are made in the outermost section chambers to form recesses for accommodating door locks, hinge assemblies and the like. An additional piece, preferably in the form of a light metal casting or a sheet metal stamping, is provided and forms an outer cover for at least a bottom portion of the central pillar.
Abstract:
A cast light metal joining element and method of assembly with adjoining extruded light metal hollow section bearer member of a space frame type vehicle body. The joining element or casting includes at least two spaced apart, location points disposed along a surface wall thereof. The location points permit the casting to be held in a corresponding fixture at a desired positionally correct spatial orientation to facilitate the fitting and connection of adjoining frame elements with greater ease, accuracy and smaller tolerances. In one embodiment, the location points include integrally formed conical studs and/or conical depressions. In another embodiment, the location points include through-holes, either straight cylindrical or conically tapered. The studs, depressions and/or holes also served a dual function in providing a positive locking connection to add on components which have corresponding matingly engagable connection surfaces.
Abstract:
A center pillar in a motor vehicle constructed of two light metal extruded sections including a first extruded section having one vertical side cut at an acute angled .alpha. over its length and a second extruded section of a uniform cross section. The cut side of the first extruded section is mated to a vertical side edge of the second extruded section in such a way to produce a center pillar having a gradually tapering thickness from bottom to top. The first extruded section includes a bend region at a lower terminal end portion thereof which diverges from the first extruded section and which is cut at an acute angle for smooth transitional connection to a bottom disposed lengthwise connecting member. A plate member is provided for covering the gap created by the divergence of the first extruded section relative the second extruded section.
Abstract:
The invention concerns an improved welded joint in a vehicle bodywork for connecting two mutually perpendicular extruded aluminum pieces such as a longitudinal bearer or sill and an upstanding B post. According to the invention, the bottom end of the B post is inserted within an opening in the sill for a positive locking engagement and includes a transverse weld seam which connects the B post to the opening along a first outward facing wall portion of the B post. In addition, a connecting member in the form of a flat plate is placed along the inward facing wall of the B post and is joined at a vertical side edge to the B post by a first weld seam and has a bottom side edge oriented flush with the upper sill surface in the lengthwise direction of the sill and is joined thereto by a second weld seam. The welded connection of the two mutually perpendicular aluminum frame members through the use of a separate plate provides a simple and economical solution which ensures a positive and strong connection in the transverse direction of the vertical member and overcomes the problems of material weakening from thermal influences of a completely surrounding transverse weld connection.
Abstract:
A holder for attachment to the underside of a vehicle bodywork for use as a suspension seating. The holder consists of a twin-chambered, extruded aluminum section, which is generally L-shaped in cross-section, and includes a first substantially upright box section which forms the support arm, and a second substantially horizontal box section which forms the support seating surface. The upright support arm is secured, preferably by welding, to a longitudinal support member of the vehicle bodywork. The L-bend region of the support arm includes an internal connecting ridge member which further stiffens the holder in the direction of loading. The bottom seating surface is provided with a relief portion for receiving the protruded end associated with a car jack, a straightening bench, a transport frame, etc. In accordance with the method aspect of the invention, the holders are cut at predetermined section widths from a single extrusion such that both left side and right side holders are made from one extrusion.

A battery for a motor vehicle includes a battery housing in which at least one cell group having a plurality of electrochemical cells is accommodated, wherein the cells of a cell group are held on a respective cell carrier, wherein a cover part of the cell carrier includes a coolant conduit for cooling the cells of the cell group. The cell carrier thus combines a holding function and a cooling function, and for this reason such a battery has a particularly simple design and is particularly lightweight. Good heat dissipation is ensured by the large surface area of the cover part.
Abstract:
A light metal casting for use in combination with a metal holder for mounting heavy subassemblies, such as doors or the like, to a light metal frame member of a light metal vehicle body framework, including a first, vertical leg portion having an outward facing surface to which a metal holder is mounted, and a second, inwardly-extending horizontal leg portion connected at an upper end of the first leg portion. The second leg portion is provided with a vertical through-hole oriented transversely to its surface, and, at the edge of the opening which faces the first leg, an upstanding tongue member is formed integrally on the second leg which points away from the first leg and can be bent over the holder. In order to fasten the holder to the light metal casting, the holder is first placed against the outer side of the vertical first leg, whereupon the tongue is bent in the direction of this outer side of the first leg and turned over the holding part until it presses the latter against the outer side of the first leg to hold it fast against the light metal casting. The holding part can thus be mounted on the light metal casting in a simple manner and very quickly, since it is only necessary to bend over the tongue.
Abstract:
A front end bearing structure for the bodywork of a vehicle of the type including a pair of spaced apart left and right side front longitudinal bearer members, each having an upstanding, substantially perpendicular support member for supporting a suspension strut mount at a location above its respective front longitudinal bearer member. Each suspension strut mount is also supported at a front end portion thereof by an additional slanted supporting bearer member which is extended upwardly and rearwardly from a connection point on each front longitudinal bearer member at a point in front of the location of the juncture of the perpendicular support member and front longitudinal bearer member. In this way, each slanted supporting bearer member forms a closed triangular framework with its respective front longitudinal bearer member and perpendicular support member. The angle subtended by the slanted supporting bearer member and the longitudinal bearer member is preferably about 45.degree.. The resulting geometry provides for a stable and rigid connection and also promotes the favorable distribution of impact forces throughout the bearing structure in the event of a head-on collision. In an alternate embodiment, the perpendicular support member for the suspension mount is enclosed by a hollow section along its entire length to form a favorably rigid closed cross-sectional bearer member.
Abstract:
An improved rear end design for a vehicle body including a first, upper cross member and a second, lower cross member fitted one over the other to form a compound beam. Each cross member is preferably formed as an aluminum extrusion. The upper cross member has the same contour shape as the lower edge of the access door for the trunk. The lower cross member lies below the level of the trunk floor and includes a middle region contour having a curve which matches a corresponding overlying middle region of the upper cross member. Each side end of the lower cross member curves forward under the trunk floor and is joined to a corresponding end of a pair of transversely spaced longitudinal side bearer members or impact-absorption units. The invention provides for a stable rear-end construction, particularly at the joints with the rear impact-absorption units, and also forms a support edge for the trunk-access door. The invention also results in less extensive repairs in the event of a rear collision.
Abstract:
The invention comprises a bearing structure for the bodywork of a passenger car wherein front suspension strut mounts are arranged above front longitudinal bearers running down both sides of the vehicle body and are supported by vertical connecting members thereon. A hollow section bearer, acting as a suspension strut bearer, connects the suspension strut mount to a joining element (node) at the middle region of the forward doorpost. According to the invention, the suspension strut bearer is curved such that it will buckle due to a reduction in the radius of curvature in the event of a head-on collision. The buckling action of the suspension strut bearer reduces the force acting on the doorpost, thereby counteracting any possible stressing of the vehicle door. In a further embodiment of the invention, slots and/or notched grooves are provided in the side walls of hollow section bearer to promote the buckling process. In another alternate embodiment, the upper and lower walls of the hollow section bearer are configured as outwardly or inwardly pointed roof structures which act as hinge axes to collapsed the hollow section bearer inward onto itself during the buckling process.
