Description

The present invention relates to a sprung drive and drive for rail-mounted monorails according to the preamble of claim 1.

Suspended vehicles and drives are used in rail-mounted monorails, commonly referred to as "suspension railway", used, for example, for passenger transport in urban agglomeration traffic in a plane above the individual transport. They are conventionally made of articulated articulated trains, which have an odd number of vehicle parts, of which in each case the first, third, fifth, etc. vehicle part of two driven trolleys and / or non-powered drives are supported on a designated rail free-floating hanging and out , In this case, these vehicle parts are the two-speed suspension of the drives / drives resiliently and connected for cornering pivotally with these and there are further provided means to make the interfaces between the car body and the drives / drives particularly safe and comfortable for the passenger.

From the DE 83047 A and CH 6598 For example, a high-lift with free-hanging hanging passenger car is known in the individual cars hanging over a spring suspension under rigid carriers to two solid in itself and directly connected to motors bogies that can run on one or two rails. After this principle was The world-famous Wuppertal suspension railway was commissioned in 1901 as a monorail monorail system and is still an attractive means of public transport. For safety against derailment or jumping off the bogies from the rails, the attachment of two counter-rollers, which are usually not applied and only in emergencies in action serves.

The DE 10 2009 058 498 B4 shows a conveyor system, in which the carriages on two in the direction of travel in pairs spaced tandem wheels move on an upper and a lower rail. By means of a double cardan suspension, they can be adapted to all horizontal and vertical curved sections of the track, monorail vehicles designed as individual gondolas being rotationally fixed with respect to their vertical axis and pivotally connected to the chassis with respect to the transverse axis.

The DE 1 405 548 discloses monorail vehicles which are resiliently suspended on elastomeric bogies via supporting articulation systems, which in turn are supported by a slot in a hollow track beam and guided laterally by four horizontal guide rollers.

Finally, the shows DE 30 23 293 Al a rail-mounted chassis, in which in the sense of axle suspension, a chassis frame on swing resiliently supported on the wheelsets and a car body resiliently on a chassis frame. By this elaborately designed arrangement in particular the pitching movements of the landing gear should be limited.

In a rail-mounted monorail, the elements in the main load path must be particularly safe. For the transmission of weight load thus the design of the interfaces between the car body and chassis / drive with the components of the Wagenkastenanbindung is of particular importance. One of the most critical elements in the entire system here is a known turntable, which allows the necessary turning between car body and chassis / drive when cornering.

For the comfort of a rail-mounted monorail, it is indispensable that the car bodies are suspended from the travel / drives cushioned, preferably with a two-stage suspension. This may neither hinder nor worsen the other functions, such as the straight-line running of a monorail typically arranged in succession chassis / drive wheels and in particular may not encourage the system to unpleasant vibrations or shocks.

The object of the present invention was to provide such a drive and drive, which ensures safe and comfortable operation with the simplest possible structure.

This object is achieved by a drive and drive with the features of claim 1. Further embodiments result from the features of the dependent claims 2 to 16, the content of which is expressly made part of the description without repeating its wording here.

The advantages of the invention are in particular that with the inventive components of the drive and drive and its Wagenkastenanbindung with simple design means all safety requirements for the operation of a rail-mounted monorail of the generic type are met. In addition, the arrangement shown allows the car body to run perfectly smooth and without reinforcements in aluminum integral construction. This benefits a weight-saving lightweight construction as a whole, which is of crucial importance for a rail-bound monorail with a weight-limited roadway.

Passengers benefit from a new driving experience by increasing ride comfort. For the operator, these include shorter cycle times, higher transport capacity, maximum reliability and lower life-cycle costs.

In this case, two successively arranged chassis / drive wheels (23, 23 ') according to FIG. 12 each two flanges (50) for tracking on a running rail (11). Each chassis / drive wheel (23, 23 ') has a permanently connected to this axle shaft (53), which on both sides of a chassis / drive wheel (23, 23 ') is rotatably mounted in fixed bearings (54).

This results in a rubber layer spring (58) together with the Rubber Winkelfedern (59), as well as from the FIGS. 10 and 11 can be seen, one for a primary spring stage (61) favorable arrangement of a three-point support (62). In addition, the transverse rigidity of a drive / drive (21, 21 ') by the design of a primary spring stage (61) with variation of the characteristics of a rubber layer spring (58) and / or the rubber angle springs (59) can be influenced in a simple manner. In addition, the arrangement of an inventive primary spring stage (61) in a drive / drive (21, 21 ') for a rail-mounted monorail of the generic type results in a low unsprung mass.

Further, on an outer side (52) according to FIG. 12 a non-driven drive (21 ') by attaching a known motor / gear unit (63) via a flexible coupling with the wheels (23, 23') and be upgraded to a driven chassis (21).

By arranging a rubber layer spring (58) on an inner side (51) and the rubber angle springs (59) on an outer side (52) of a chassis (21) is a motor / gear unit (63) via a primary spring stage ( 61) cushioned and additionally given a sound insulation to a car body (19, 19 ').

In addition shows FIG. 12 the adjustability, which can be made from the center of a running rail (11) to the center of a car body (19, 19 ') according to its center of gravity position by appropriate positioning at a distance "D".
