Abstract

The couplable bogie proposed is equipped with a rigid frame for carrying and tilting the body of a high-speed rail vehicle. The running gear bogie has a movable unit (11, 11') with at least two individual wheelsets (2, 3, 2', 3'). These are mounted in pairs on a common frame (4, 4') which rests via direct spring suspension (5, 5') on each wheelset (2, 3, 2', 3'). Also fitted are means (9, 9') for carrying and tilting the vehicle body (8, 8'). The frames (4, 4') are connected to each other by a separable coupling system (6, 6'). The system has a zero-length coupling half to which is linked a control device (7, 7') for controlling the position of the wheelsets (2, 3, 2', 3') as a function of the radius of the curve. This gives a couplable bogie with a rigid frame for carrying and tilting the body of a high-speed rail vehicle.

Description

The coupled arrangement of the chassis car body

Technical field

The invention relates to a coupled bogie arrangement with a rigid bogie frame for supporting and transversely tilting a vehicle body for fast-moving rail vehicles.

BACKGROUND OF THE INVENTION

WO 87/05 873 discloses to the prior art a low-floor rail vehicle which consists of two gantry drive individual bogies or two driven bogies with steered wheels, which are connected to one another by a support and supply unit and form as a gantry a support and travel unit for passenger or utility cells in the form of a container.

Such gantry bogies allow extremely low floors to pass in one plane along the entire length of the vehicle, but have a relatively high center of gravity with respect to the aggregates located in the support and supply unit, so that they are not suitable for fitting a lateral tilt device. The steerable single wheels are well suited to the driving forces in curved arcs and thus to a considerable reduction in wheel abrasion, rails for small bend radii such as those found on street tracks, but bring not only significant problems with fast-moving rail vehicles. by running the wheel to one side and with a tipping moment the free wheel bearing on its very small base.

WO 91/02673 shows two steerable uniaxial bogies which are inseparably connected to each other by the transmission of the driving and braking forces of a rigid and, in terms of use, a flexible coupling which serves to accommodate a low-floor vehicle body positioned at a specified distance from the axis.

However, the combination of a low floor with a vehicle tilt device is not mentioned in this solution.

IIS-PS 2 893 326 discloses fast-acting rail vehicles with single-wheel bogies and single-stage suspension on which it is supported with the possibility of lateral tilting of the low-floor vehicle body.

This solution relates to a stationary, undetachable train set, in which the car body is supported on the bogie with a single wheel and on the bogie preceding the adjacent body of the car, so that each individual bogie with a gear is automatically adjusted radially when curving.

In order to be able to accommodate the fluctuations caused by the occupants, individual detachable vehicles are advantageous in operation.

In the arc radially adjustable individual bogies with the gearing, which are located in a pair under the vehicle body and which are mutually adjustable radially to the arc, can be seen from CH-PS 329 987.

SUMMARY OF THE INVENTION

SUMMARY OF THE INVENTION It is an object of the present invention to provide a coupled bogie arrangement for supporting and transversely tilting a vehicle body for fast-moving rail vehicles.

This object is achieved by the features set forth in the characterizing portion of the claims.

To this end, there are two controllable individual bogies

it is provided with a direct application on which it is opioidly rigid.

a bogie frame connecting the two individual bogies to the gearing, which is formed as a supporting part for accommodating a low-floor car body in the form of a container and between them is a device for transverse tilting of the body.

An embodiment of the invention provides a low-floor high-speed rail vehicle in which the bogie frame together with the two individual bogies form an autonomous unit. These vehicles can travel at high speed arcs without passengers being subjected to increased centrifugal forces or a pair of wheels, the rail being subjected to high forces and increased abrasion.

This problem has not been solved in the prior art by known means.

Each two individual bogies 2, 3, 2 ', 3' are connected to each other by means of bogie frames 4, 4 'located at a specified axial distance and transmitting driving and braking forces. This results in separate mobile units 11, which can be coupled to one another via the coupling system 6, 6 '. and have the advantage over conventional swivel bogies, for example, that they can be transported separately suspended on a train without being loaded onto a transport wagon. Each mobile unit 11 '' serves to accommodate the car body 8 '' in the form of a container. The body 8, 8 'may be self-supporting or non-self-supporting while being supported on at least the longitudinal frame of the P-frame 4, 4'. The chassis frames 4, 4 'may also be identical to the pedestal 8, 8' of the car. '. - - '
