According to the invention, the connection between the truck (1) and the trailer (2) consists of a pivoting linkage (13, 19, 37) pivoting about an axle (43) or (26) generally perpendicular to it, forming part of a pivot center (18) attached in overlapping arrangement to the front part of the tailer chassis, and of at least one oblique connecting rod (20, 39, 40) of constant length, extending obliquely in relation to the straight line direction between the truck (1) and the trailer (2). The invention is of interest to vehicle manufacturers, especially trailer manufacturers.
摘要:
Coupling for controlling the angular offset between two road transport units (A and B) connected to one another by an intermediate self-supporting unit (C), unites (A) and (B) being respectively oriented thereto at angles .alpha. and .beta., the intermediate unit (C) being articulated to units (A) and (B) by two swiveling articulations (D) and (E). The invention consists of an oblique coupling (F) extended by a diverter (H) controlled by a cam actuator (I) for yaw angular offset control based on a law for the angular correction of angles .beta. as a function of angles .alpha., having a central region with a slight slope terminated at each of its ends by a transition region. The invention is of interest to manufacturers of articulated public road transport vehicles.

A wheel support system according to this invention comprises an elongated generally horizontal support beam having an upwardly directed upper surface, a horizontally inwardly directed front surface, and a horizontally outwardly directed rear surface and a pair of identical arm units unconnected with and wholly independent from each other. Each arm unit includes a horizontal arm disposed generally perpendicular to the beam and having an outer end formed as an abutment directly engaging the front surface of the beam and an upwardly directed flank adapted to tangentially engage a tire surface of a wheel to be supported and a hook having a lower end connected to the arm at the abutment and an upper end, a depending part engaging the rear surface of the support beam, and an upper part operatively engaging the upper surface of the support beam. The hook and arm of each arm unit are relatively fixed and nondisplaceable. The identical arm units are angularly oriented 90.degree. out of phase with respect to each other so as to in effect be mirror images of each other.
摘要:
A system for loading, unloading and rail transportation of road-hauled semi-trailers, having multiple wagons (1) constituting a railway train, with each of them incorporating at least one pivotable turntable (14) for accommodating a semi-trailer via its wheel assembly. The system also comprises a detachable hitch mounting (9) that can be gripped by a handling machine which carries the detachable mounting and assembles it, after adjustment on the semi-trailer's pivoting turntable. The hitch mounting is assembled on an accommodating platform (8) that is secured immobile to the wagon chassis (2) and independently of the pivoting turntable, in order to support the front of the semi-trailer during rail transportation. This invention is of interest to rail carriers and railway transport equipment manufacturers.
摘要:
A prefabricated module (1) to be used in constructing a track for an urban transport vehicle. The module comprises an integral carrier structure (2) made of concrete and comprising two side sills (4) having an upper surface (5), used as a driving pathway for the vehicle wheels, and connecting crossbars (8) which connect and retain the sills substantially parallel to each other. The lower surfaces (6, 39) of the sills and crossbars are ground-bearing surfaces. A guiding rail section (3), mounted on the carrier structure, is preferably symmetrical, has an I section and a lower portion coated with a liner material (13). The modules, whether rectilinear or curved, are to be placed on an existing road layout or in a trench with a compacted bottom, and are connected one after the other to form the driving track.
摘要:
An auxiliary and motive electric power pick-up structure for articulated and non-articulated land vehicles, such as electric public transport vehicles, that pass close to a collector-shoe-type power supply member mounted on a stationary support (17) along the route of the vehicle and positioned at intervals along the length of the route in order to provide auxiliary and motive electric power to the vehicle by way of the shoe (16). The structure comprises at least one conductor rail mounted on insulating supports (11) attached to the vehicle by suspension points (34), each including an elastic suspension unit (30) and a pneumatic, hydraulic or other type active suspension unit (33). In the case of articulated vehicles, the pick-up structure is divided into power supply segments (14) separated by a conducting link (19) at each articulated unit of the vehicle.
摘要:
The invention relates to an anti-extraction safety device comprising, for each roller (13, 14), a rotatably fixed, preferably enveloping, shroud element (32, 33) forming a one-piece functional mechanical assembly with its counterpart. The base of the shroud elements has an extension (46, 47) which extends beneath the projecting flanks (21, 22) of the head of the guiding rail (19) in order to prevent any extraction of the guide assembly. At the front, the base of the shroud elements is preferably shaped as a lip for collecting and disposing of objects which may be present on the guiding track. The invention can be used for the rail guidance of road vehicles used for public transport.
摘要:
A sliding body (25) which includes an electrical contact shoe (32) that moves on a guide rail (5) along the length thereof. The sliding body (25) is mounted to the front of a guiding assembly, in the direction of movement of a vehicle, and articulated with the assembly by a connecting rod (26) that is designed to rupture upon exceeding a pre-determined limit. The sliding body (25) includes a device (43), which is located on at least one of the sides of the body, for lifting and releasing objects or debris. The loss of electrical contact between the shoe and the rail enables a risk of derailment to be detected. The invention is suitable for rail-guided vehicle manufactures.
