SU110912A1 - Trolley for high-speed monorail railway rolling stock - Google Patents

Description

Trucks d; 1 rolling stock of high-speed monorail railroad gantry, consisting of two pairs of wheels, are mounted on the bottom shelf on both sides of the I-rail monorail, and connected by a traverse, equipped with a swivel near the longitudinal axis of the harness, suspension suspension for the body are known .

In the known carriages, the deviation of the car body in two directions is not impoverished: in the direction of travel and in 15 directions transverse to this movement. By virtue of this, when the rolling stock passes the curves, the carriage is loaded with tilting moment from the body of the surge.

The cart of the invention is free from the above disadvantage.

The essence of the invention is that the suspensions are connected to both the traverse hinge and the body with ball joints.

FIG. 1 is a schematic side view of the undercarriage; n f1p 2-wnd on the side of the MOTopHoii te.1ezhk11; on f | n-. 3 is a section through LA in FIG. one.

The carriage of the rolling stock (wagon) is mixed along the shelf of the asymmetrical I-beam. It consists of two two wheel pairs 2, connected by a traverse 3. The traverse rests on the bracket 4 of the wheelset via a shock absorber.) Thus, the non-sprung in the carriage is the same mass of the bunker.

Traverse 3 is equipped with a HOBOPOTHBINL about longitudinally. The shipyard bears the suspension 7 for the body 8 of the train. Suspension 7 is connected both with iHapniiir (;, and with Lvagon bodywork Hjapov hinges) 9, 10. The traverse of the TopHoii trolley is carried by the y.edh iee wheel //, Akmpeo interacts with n; 1 the outer surface of the monorail, and is equipped with two rotary

each of which carries suspension 7 for the car body.

Two devices are provided to reduce the oscillation (swing) of the car in motion. The first (not shown) - hydraulic shock absorber (damper) in the hinge (3. Second - flaps 12, the opening of which is automatically adjusted when the car body deviates from the vertical position. When the car body deviates to the left, as shown in Fig. 3, it opens the right flap, which tends to return the car body to a vertical position. When the car body is deflected to the right, the left lock locks open.

In addition to the automatic drive, the control of flaps is possible from the driver’s brake crane, which uses them as aerodynamic brakes when driving at speeds above 100 km / h.

In the proposed trolley, the presence of a ball joint of body hangers with it and with a hinge on the traverse makes it possible for the call of the car to deviate in the direction of travel and in the direction perpendicular to this direction, unloading the cart from overturning 11, their moments, and that is of great importance for high-speed transport.

Subject invention

A trolley for rolling stock of a high-speed monorail suspended railway consisting of two pairs of wheels supported on a lower shelf on both sides of the I-rail monorail vertical wall and connected by a traverse equipped with a hinge, rotatable about the longitudinal axis, for a body, characterized in that For the purpose of some tolerable deviation of the body, both in the direction of movement and in the direction perpendicular to it, the suspensions are connected to the hinge and the bodywork with nomop1; spherical hinges.
