Abstract: A gangway bellows is used as a cross-over shelter between two vehicles which are flexibly connected to each other. The sidewalls of the gangway bellows have a double-wall design. Each internal wall is constructed as a curtain, which is suspended at its upper end from the roof of the gangway bellows and ends with its lower end immediately above a crossover unit, between the vehicle sections, having a turntable. The inner walls cover the track groove and, between themselves and the side walls of the gangway bellows, form chambers in which service facilities can be accommodated. Each curtain is folded preferably to correspond to the gangway bellows. Support elements may be interposed between each curtain and the respective side wall of the bellows.

Abstract: A vehicle system for local public passenger transportation, in which a number of vehicle components are used to realize a vehicle system according to a building-block system.

Abstract: An arrangement for bridging adjacent cars in high speed railway vehicles posed of an inflatable chamber bellows section which extends entirely or partially about the outer structure of the cars wherein the stiffness of the bellows section may be automatically adjusted to respective requirements of high speed travel and travel through curves in such a manner that the internal pressure in the chambers of the bellows section which is produced by inflating the section is controlled in a stepless manner or in individual steps by a control system supplied with fluid pressure through the compressed air system of the vehicle or from a compressor.

Abstract: A tunnel structure for interconnecting passenger compartments on an articulated vehicle includes pairs of cylindrical walls which overlap during steering movement of the vehicle. To seal between the cylindrical walls, a pair of inner walls is provided which include hinged flaps lying against the cylindrical wall. The flaps are hinged on an inclined axis to reduce clearance between the cylindrical walls and the side walls upon the vehicle negotiating vertical curves.

Abstract: A damping system having a fluid-operated friction device located at the hinge connection of an articulated vehicle that provides progressively increased damping to movements about the yaw axis after the speed of the vehicle increases beyond a predetermined speed.

Abstract: An arrangement consisting of coupling elements allowing both pitch and yaw pivotal motion between two coupled modules or coaches, is disclosed. A transverse rod located at the end portion of one module is rigidly secured to a pair of arms and is supported thereby. These arms are rigidly connected to a king-post located in a casing. The king-post is adapted to pivot about its vertical axis. The end portion of the other module is provided with a pair of longitudinally-oriented shafts, each having an outer end provided with a pair of jaw members. The latter can open and close to effect coupling of the modules and are adapted to pivotally grip jaw-receiving portions on the transverse rod.

Abstract: Bridging structures are arranged between adjacent cars of trains, for exae high speed, track guided trains or between the sections of buses having at least two sections. A first type of bridging structure provides a sealed walk-through passage between adjacent cars or bus sections. A second type of bridging structure provides a transition or continuity between adjacent cars or bus sections at the outer housing or shell wall thereof for assuring a streamlined or flush continuity between adjacent cars or bus sections. Both types may be used in combination whereby the first sealing type bridging structure is arranged inside the second type which provides the streamlined or flush continuity at the outer housing or shell wall of a railroad car or bus.

Abstract: A hinge connection for an articulated vehicle having a front section provided with two longitudinally spaced nondriven axles and a rear section provided with a single driven axle. The hinge connection is characterized in that it includes a pair of hinge members which, together with a linkage mechanism, are connected to a transversely extending shaft member so as to provide angular movement of each section of the vehicle about a pair of mutually perpendicular axes while ensuring that the longitudinal center axis of the shaft member always bisects the angle between the front and rear sections when the vehicle is in a turn.

Abstract: A vestibule connection for the adjoining ends of two cars of a rapid-transit vehicle includes an apron which is maintained centered in the space between turntables at the adjoining ends, by being mounted on two transverse parallel shafts via telescopable units that are pivoted to these shafts and alternate ones of which, as considered in direction lengthwise of the shafts, exert a biasing action on the apron in mutually opposite directions along the centerline of the two cars.

Abstract: An articulated tractor that has its front and rear sections pivotally connected along the tractor's axis of articulation. The lead surface of the rear section and the trailing surface of the front section form an articulation space which is in close proximity to the articulation axis. To improve this arrangement, a cover is provided which substantially encompasses the articulation space with an enclosure. The enclosure incorporates at least two flexible bellows, which are opaque between their forward, rearward, top and bottom edges. The enclosure also includes four bands, a plurality of elements rigidly securing one of the bands to each of the forward and rearward edges of the bellows, and a plurality of members rigidly secured to the bands. The cover also utilizes a support to pivotally support the enclosure. This support is rigidly secured to either the front or the rear section of the tractor.

Abstract: A bellows connection adapted to be disposed between a front and rear section of an articulated vehicle. The bellows connection includes a first and second bellows part with at least one of the bellows parts being mounted on an end frame of one of the sections of the articulated vehicle. Both of the bellows parts are connected to each other by a portal-like bellows yoke which is saddled-mounted to the front section in a ball joint at the bottom so that it is omnidirectionally pivotable. A lemniscate control arrangement is provided for guiding the bellows yoke along a bisecting line of a bending angle between the front and rear sections of the vehicle. To provide for additional guidance and support of the bellows yoke two struts are provided in a roof area of the vehicle in a vicinity of the central longitudinal axis thereof. The struts are articulated to the front or rear sections of the vehicle and to the bellows yoke.

Abstract: A system for articulated bogie-type rail vehicles in which the adjacent ends of the car bodies are pivotally and rotatably supported by supporting arms extending beyond their end trusses on a single-part connecting portal jointed by bellows to the car box ends and mounted on a transverse support. The portal is tightly enclosed by a sealing member on its full perimeter and has a spring mounted platform supported with vertical freedom of movement but with minimum play in all other directions on the bogie. This platform is pivotally arranged by at least one centrally located rotation ball race and by the supporting arms. This rotation ball race has three race rings and two rows of balls. Of these three race rings one race ring is kinematically associated with the front car body while another race ring is kinematically associated with the rear car body, and the third race ring is kinematically associated with the transverse support supporting the portal and the platform.
