Abstract:
In one embodiment, a vehicle for transporting passengers can include a chassis, a support member, and a labyrinthine girder. The support member can be rigidly engaged to and project from the chassis. The labyrinthine girder can include a coupling platform that is coupled to the support member. The labyrinthine girder can form a partial enclosure that surrounds a portion of the frame rail. An offset distance can be disposed between the labyrinthine girder and the frame rail.
Abstract:
This invention pertains to a method of reconfiguring a family of the armored, tracked vehicle of the troop carrying type to enhance producibility and protection from mine blast fragments. By using the configuration and modification disclosed herein, mine blast protection, verticle obstacle crossing capability and cross country mobility are enhanced.
Abstract:
The object of the invention is an ice-maintenance machine, which includes a steerable vehicule (2), a water tank (15, 16), a platform (4) for icy slush, an ice-maintenance unit (1) propelled by the vehicle, and a removal conveyor (3) for transferring the icy slush from the ice machining unit (1) to the platform (4) and in which the vehicle (2) includes a chassis (5), front and rear axles (8, 11) with wheels (27, 28), a motor (24), and transmission devices connected to the axles including a cardan axle (22) between them and a distribution gearbox (23). A low structure is achieved when the chassis (5) is formed of a box structure, which itself forms the water tank (15, 16), and that the centre of the chassis includes a longitudinal channel (7) for the cardan axle (22) and the distribution gearbox (23).
Abstract:
Commercial and special-purpose vehicles, for example weapon-carrying vehicles, mobile radar stations, mobile satellite control stations and automatic cranes, which carry a heavy load require a very robust chassis. The chassis (1) according to the invention is of so-called box-type construction. It comprises a lower and an upper support plate (2, 3) reinforced by and connected to reinforcing elements (12) located between the plates. This construction results in an enormous carrying force and exceptionally high rigidity against deformation with very low chassis height. In contrast to conventional chassis constructions having a total height of 30-40 cm, minimal heights of approximately 10 cm are possible with this chassis. Additional reinforcement is obtained by covering the external fronts of the chassis with vertical covering plates. These measures make it possible to obtain a shape which permit very low mounting of the chassis even when big wheels are used. The chassis according to the invention makes it possible to use telescopic axle suspensions, such as those described in Patent application No. 531/87. This makes it possible to adjust the vehicle position during motion and without additional devices. In addition, a construction of relatively low weight is obtained.
Abstract:
Die vorliegende Erfindung betrifft ein selbsttragendes Untergestell für ein Fahrzeug sowie ein solches Fahrzeug und ein entsprechendes Herstellungsverfahren. Aus Faserverbundswerkstoffen gebaut haben sich vor allem Untergestelle aufbauend auf einem Monocoquedurchgesetzt. Auch sind Monocoques bekannt, die Verstärkungselemente aufweisen. So ist es beispielsweise bekannt in einer Tragwanne lang gestreckte Verstärkungselemente anzuordnen. Die vorliegende Erfindung hat es sich zur Aufgabe gemacht, die Masse zu reduzieren, die Steifigkeit und die aufnehmbaren Kräfte zu erhöhen und das Ergebnis einer Umwelt orientierten Gesamtbetrachtung zu verbessern. Gelöst wird die Aufgabe durch ein selbsttragendes Untergestell aufweisend zwei parallel und voneinander beabstandet angeordnete, lang gestreckte und anmindestens vier Seiten zu mindestens 50% verschlossene Monocoques, wobei die Monocoques jeweils ein einteiliges wannenartiges Element (1) aufweisend mindestens einen unteren Boden (14) und zwei sich vom Boden aufwärts erstreckende Seitenwände (13) und mindestens ein die wannenartigen Elemente über mindestens 50% der Längserstreckung des jeweiligen wannenartigen Elements verschließendes Deckelement (2) aufweisen, wobei das mindestens eine Deckelement eines jeden der zwei Monocoques jeweils mindestens ein Verstrebungsdeckelement (2) beinhalten und die Verstrebungsdeckelemente der zwei Monocoques als gemeinsames einen zwischen den wannenartigen Elementen der Monocoques liegenden Zwischenraum überspannendes einteiliges Verstrebungsdeckelement ausgebildet sind und die Deckelemente mit den Seitenwänden der Monocoques fest verbunden sind.
Abstract:
A space frame (12) for a machine (10) is disclosed. The space frame may have a first end (42) configured to be connected to front wheels (14) of the machine. The space frame may also have a second end (44) configured to be connected to rear wheels (16) of the machine. Further, the space frame may have primary structural members (56) arranged substantially lengthwise between the first end and the second end. In addition, the space frame may have secondary structural members (58) connected between the primary structural members to form substantially triangulated structures (60, 62) allowing the space frame to support a payload to empty vehicle weight ratio ranging from about 1.2:1 to 2:1.
Abstract:
The frame (2) comprises a pair of self-propelled lateral modules (3), which extend in a longitudinal direction, can be mutually coupled in a transverse direction and in a removable manner, and are adapted to contribute to create, when assembled, a support structure for a central module (5), which can be coupled in a removable manner to the frame (2) and is provided with a control system, which is configured to control the movements and the actuation of the self-propelled lateral modules (3). Each one of the self-propelled lateral modules (3) comprises a pair of bearing portions (10), and a connection portion (12), which mutually constrains the bearing portions (10) and is able to permit a relative movement thereof between an extended configuration, in which the bearing portions (10) define a greater longitudinal extension of the self-propelled lateral module (3), and a compact configuration, in which the bearing portions (10) define a smaller longitudinal extension of the self-propelled lateral module (3).
Abstract:
There is disclosed a chassis (100) for a high mobility vehicle, the vehicle defining a longitudinal axis (101), the chassis (100) comprising a tubular transmission member (110) generally parallel to the longitudinal axis (101) and extending from a foremost axle to a rearmost axle and thus defining a transmission axis (101) at least one structural member (122,124) the tubular transmission member (110) being connected to the at least one structural member (122,124) wherein the chassis (100) comprises at least one foremost attachment means (220,221) whereby recovery means may attach to the chassis (100), the attachment means (220,221) being arranged with one of the structural members (122,124) such that recovery loads are transmitted through the said one of the structural members (122,124).
