Description

The invention relates to the field of land high-speed transport, and in particular to transport systems with a given trajectory, and can be used in mounted monorail vehicles intended for passenger and freight traffic.

Known monorail running track and a vehicle, which is a transport system (invention RU 2269444, 02/10/2006). The running path is made in the form of a monorail and a sheet metal box open from below with transverse stiffeners periodically installed inside it. In the lower part of the box there are longitudinal lateral protrusions with a half-trapezoidal profile with inclined surfaces up, and in the upper part there is a recess for installing a monorail. The vehicle has a platform on which, with the possibility of interaction with the upper shelf of the monorail of the running track, central drive support wheels and two pairs of passive side wheels spaced apart in height, mounted to interact with the side planes of the running gear box, are installed.

The presence of a box-shaped element in the track makes the design easier and cheaper, however, the system requires constant balancing and does not provide reliable traction of the wheels with the track, which limits its use as a public transport in the suburban area.

A mounted monorail transport system is known, in which the monorail and the running gear box are made in the form of a single box structure, the drive wheels of the vehicle platform interact with the inclined base of the monorail, and the pairs of passive rollers with the roadway (utility model RU 86918, 09/20/2009 )

The design flaws include the low traction power of the drive wheels with the monorail, which reduces the reliability and safety of movement.

The suspension transport system according to the invention RU 2302955, IPC B61B 3/02, B61B 13/04, publ. July 20, 2007. The system contains a track in the form of a U-shaped beam suspended by central struts, and a vehicle with upper support wheels mounted to interact with the upper horizontal surface of the beam, lower pressure drive wheels installed to interact with lower horizontal surface of the beam, and paired auxiliary rollers of lateral stabilization. In this case, the lower rolling plane of the drive wheels of the beam has a coating of material with a high coefficient of adhesion.

The presence of replaceable coating elements in the prototype does not provide sufficient traction of the drive wheels with the beam in rough terrain, especially on descents and ascents, which negatively affects the safety of the vehicle.

The task underlying the invention is to create a reliable suspension system design that ensures the safety of passengers and goods in rough terrain, in remote areas, as well as in natural areas with the status of nature reserves, reserves and national parks.

The technical result is an increase in the reliability of the coupling of the drive wheels with the beam of the track by using the mass of the vehicle, ensuring the safety of the system as a whole.

The technical result is achieved by the fact that the suspended transport system has a running path in the form of a beam suspended by racks, on which pairs of support wheels of a vehicle are installed, having pairs of lower pressure driving wheels interacting with the beam. What is new is that the beam of the running track is made in the form of a Tauri, on the opposite sides of the vertical strut of which two driving pairs of wheels are placed in the horizontal plane, installed, like the upper supporting pairs of wheels on the axles of the vehicle frame. Two-arm levers are placed on the axles of the driving wheels, which are paired on each side of the beam with a tackle pulley passing through four mounted on the frame of the roller, with the earring of the load-carrying subframe, which is pivotally suspended from the side of the earrings to the frame of the vehicle. At the same time, to control the pressure of the driving wheels against the beam, depending on the weight of the load, the earrings are mounted on / on the guides of the load-carrying subframe with the possibility of moving along them and setting them in the optimal position relative to the load suspension.

The specified set of essential features provides reliable grip of the vehicle with the running track and the safety of the suspension transport system as a whole.

The inventive suspension transport system is illustrated by an example implementation with the accompanying drawings, which depict:

FIG. 1 - general view;

FIG. 2 is a side view;

FIG. 3 is a plan view.

The system comprises a running track, which is a beam 1 suspended on racks, having a cross section in the form of a Taurus, and a vehicle mounted on it. The vehicle has a frame 2, on the axes of which are mounted 3 supporting two pairs of wheels placed in a vertical plane on the beam 1, and driving 4 driving two pairs of wheels placed in a horizontal plane and in contact with the vertical rack of the beam 1. On the axles of the driving 4 wheels are installed rotary levers 5, and on the brackets 6 of the frame 2, a subframe 7 of a rectangular frame structure is pivotally suspended with a possibility of rotation, in the arcuate guides 8 of which there are earrings 9. The rotary levers 5 pairs of driving 4 wheels are located x on each side of the vertical strut of the beam 1, connected by a cable 10 of the polyspast system, passing through four rollers 11 mounted in pairs on the upper and lower shelves of the frame 2, with the corresponding earring 9 of the subframe 7. The transported load 12 is suspended from the subframe 7 using known means passenger cabin or cargo container.

The operation of the overhead transport system is as follows.

The weight load from the transported cargo 12 of the vehicle when turning the subframe 7 is transmitted via cables 10 to the levers 5, which, turning, tightly press the leading 4 pairs of wheels to both sides of the vertical strut of the beam 1, ensuring their reliable grip. The pressing force depending on the weight of the load 12 is regulated by changing the position of the earrings 9 in the grooves 8 of the guide subframes 7 relative to the load suspension. The directional movement of the vehicle along the beam 1 is carried out when the drive of the leading 4 pairs of wheels is turned on, which, rotating, roll along the vertical strut of the beam 1, and the upper supporting 3 pairs of wheels mounted on the beam rotate forcibly in the direction of movement of the vehicle, transferring the weight of the vehicle with cargo.

In the system proposed for protection to regulate the pressing force of the driving wheels of the vehicle to the beam, an embodiment of earrings 9 is possible, covering the guides 8 of the subframe 7.
