Abstract:
The invention concerns a stress-bearing structure of a motor-vehicle body made with hollow section beams, having at least at one structural member junction point (1) at which a first hollow section beam (2) is joined with a second hollow section beam (3) and a third hollow section beam (4), which are opposite each other on either side of the first hollow section beam. The second and third hollow section beams (3, 4) are attached to the respective opposite sides of the first hollow section beam (2) by a butt joint. The junction point (1) is reinforced by a junction point reinforcement element in the form of a hollow section extrusion (6). In accordance with the invention, a hollow section extrusion (6) is positioned beneath the structural-member junction point (1) on the inside of the vehicle body and fixed in place. The longitudinal axis of the hollow section extrusion (6) runs in the same direction as the longitudinal axis of the first hollow section beam (2). The transverse profile of the extrusion section has a greater width than the width of the first hollow-section beam (2), so that the extrusion section lies against both the second hollow-section beam (3) and the third hollow-section beam (4) with its contact surfaces (11, 13) attached to them. Lateral stresses exerted on the structural-member junction point (1) are absorbed and stayed by the hollow section extrusion (6) which functions as a tie rod. In a preferred embodiment of the invention, the hollow section beams (2, 3, 4) and the section of extrusion (6) are made of a light metal.
Abstract:
A vehicle chassis constructed of metal frame elements which are joined together by connecting node elements (connectors). The node elements are configured as upwardly open molded pieces (shells) When assembled, a bottom surface portion of each node element is received in conforming notches disposed adjacent the outwardly facing end surfaces of the joining ends of abutting frame elements in such a manner that no part of the node element forms the inward facing regions of the vehicle frame defining the windscreens and door openings. Each node element is provided with side projections (tangs) which extend beyond the notch portions of the adjoining frame elements to increase surface contact area between the node element and each frame element. A cover plate or the vehicle body skin is provided to cover the upward facing end of the node element.
Abstract:
A rear support structure for the coachwork of a passenger vehicle having closed loop interconnected frame members including a longitudinally extending bottom sill connected at its rearward portion to the forward portion of a rear wheel housing carrier member. The rearward portion of the rear wheel housing carrier member is connected to at least one roof support post which in turn is connected to the roof structure. The connection of the sill to the rear wheel housing carrier member is at a low angle, providing resistance to mechanical fatigue due to flexing and vibration, while at the same time providing a rear passenger door cutout of sufficient size to permit easy entry and egress of rear passengers. The rear wheel housing carrier member has at least two, approximately linear regions, one arcuately flowing into the other for connection of the vehicle's floor structure and two roof support posts of the vehicle bodywork. In the preferred embodiment, the rear wheel carrier member has three approximately linear regions joined by two intermediate arcuate sections. The interconnection of the bottom sill, the rear wheel carrier member, the roof support post, and the roof structure provides a rigid rear bearing structure having a continuous force flux pathway, which dissipates the energy of a side collision thus protecting passengers in the event of such a collision with the rear passenger compartment.
Abstract:
An improved bearer joint in a vehicle bodywork consisting of extruded light metal bearer members connected together by cast metal joining elements. According to the invention, an end portion of at least one bearer member is received within a concave region of at least one joining element and is connected thereto at two connection points on either side of the coverage region so that the portion of the bearer member between the connection points and overlying the concave region acts as a tension member or steadying strut depending on the direction of the load. In a preferred embodiment, the improved bearer joint is the node connector type joining element located at the middle of the A post where the downwardly and obliquely oriented forward roof post joins the substantially vertically upright forward door post. The invention provides a rigid connection with high expansion and energy absorption capabilities, thereby strengthening an otherwise critical weak point in the vehicle roof structure.
Abstract:
The invention relates to a device for connecting a vehicle operated by electrical current to a socket of a low-voltage alternating-current network, said device comprising a charging cable provided with a plug that fits the socket. The charging cable comprising the plug is arranged in a recess beneath a region of the bonnet of the vehicle that is true to the windscreen of the vehicle. The charging cable is at least indirectly connected to the vehicle in a fixed manner.
Abstract:
The invention relates to a vehicle having, at least in part, an electric drive which includes a traction battery (1), which vehicle has at least one predefined deformation zone (I, II) which in the event of a crash (A, B) acts to absorb energy, and at least one predefined zone (III), which has a substantial structural rigidity and which in the event of a crash (A, B) remains substantially without deformation. According to the invention, the traction battery (1) has a deformation region (18) which in the event of a crash can be deformed via a deformation path (a) and which is arranged in the deformation zone (I, II) of the vehicle.

A channel of a motor vehicle with a reinforcing insert. The channel serves as an essential load bearing structure of a motor vehicle. The channel is also served as a stable barrier to protect the passenger compartment in the event of a crash.
Abstract:
The invention relates to a reinforcement assembly for a sheet metal component in a vehicle bodywork by a second reinforcement piece formed as an extruded light metal section which is additionally secured thereto. The sheet metal component to be reinforced runs straight in a first spatial direction and is curved only in the other two spatial directions. According to the invention, the extruded light metal reinforcement piece is shaped to conformingly fit the curved surfaces of the sheet metal component. The sheet metal component and the reinforcement piece are preferably adhesively secured together. A preferred use of the invention is for reinforcing the sheet metal vehicle floor tub in the high peak stress region of the rear safety belt anchor points. The arrangement of the invention provides an effective reinforcement for heavy loads with good force transmission. The extruded section is preferably formed with a channel sized for receiving a nut portion of a nut and bolt fastener for securing additional components such as a safety belt anchor point, an automatic winding device, a tank support or the like.
Abstract:
An improved door pillar assembly for a passenger car coachwork formed as a substantially vertical extruded light metal hollow-section member and having an outer wall to which longitudinally spaced upper and lower hinge lugs are adjustably secured for swivel connection of a vehicle door. The extruded hollow section member includes a pair of inner transverse ridge members which extend along the longitudinal dimension and divide the hollow interior into three transversely spaced cage sections. Each of the outer cage sections further includes a longitudinal channel formed into the inner surface of the common wall to which the hinge lugs are adjustably secured. An upper and lower pair of slots are provided in the outer wall and are aligned with respect to the channels for receiving the mounting hardware (i.e., bolts) for the hinge lugs whereby the hinge lugs can be selectively positioned within the slots prior to tightening to provide a desired height adjustment. The slots are sufficiently wide to permit a desired range of transverse adjustability for each hinge lug. The hinge pin support arms of each of the upper and lower hinge lugs are transversely offset from one another such that the hinge pin may be easily positioned at a desired oblique angle with respect to the longitudinal axis of the door pillar to ensure proper fit of the vehicle door.
