SU1409504A1 - Arrangement for matching the body of rail vehicle with at least three bogies - Google Patents

Abstract

The invention relates to railway transport and concerns the construction of a multi-axle vehicle crew. The purpose of the invention is to improve the horizontal dynamics. The vertical load from the body on two-axle bogies is transmitted through a vertical pivot-lever mechanism consisting of two L-shaped levers and tons g. One of the levers is connected by three hinges respectively to the support, body and ti. The horizontal load on the biaxial bogies is transmitted from the body through a horizontal link-lever mechanism, made similar to the vertical link-lever mechanism. Each two-axle trolley is connected to a three-axle trolley using a two-arm lever located in a vertical plane and a two-armed arm located i in a horizontal plane. 1 hp f-ly, 9 ill. (L

FIELD OF THE INVENTION The invention relates to railway transport and concerns the train crew GUIDE.

The purpose of the invention is to improve the mountain; (ontal dynamics.

Fig, 1 shows the crew with three pillows, general view; na twee Pie A – A in FIG. on fig.Z - section: 5-B in FIG. 1; figure 4 - crew, top view; FIG. 5 shows a section B-B in (1 Fig. 4; FIG. 6 - section G-D in () ig 4; FIG. 7 - type D in FIG. 4; in (1) a section E -E in FIG. 4; in JIG 9, the scheme of forces acting in the mechanism,

A multi-axle bogie consists, for example: iep, of a two-axle bogie with wheel pairs 2, a two-axle bogie 3c with salt dads 4 and a middle three-axle ™ bogie 5 with wheel pairs 6,

The vertical load from the body 7 is transmitted to two-axle bogies 1 and} on each side through the supports 8 with the help of a vertical swivel-lever mechanism consisting of two-shaped levers 9 and a thrust 10, which 5a hinges 11 and connects the levers 9 . The hinges 12 levers 9: are connected with the upper plates of the supports 8, 1 by the hinges 3 - with the body 7, From the transverse displacements relative to the body 7, the hinge 12 with the upper plate of the 8) is 8 9 can only be rotated in a vertical plane relative to the hinge 13, the support 8 is connected; body 7 horizontal leash 15, pivotally connected with support 8 and holding body 7,

Horizontal load from body 7 to each biaxial trolley 1 or 3 is transmitted through a horizontal-hinged hinge-lever mechanism, consisting of: from the L-shaped levers 16 and g 17, the levers 16 are connected by hinge-Yi 18 with carts, hinges 19 with tKysoBOM 7j hinges 20 - between with ™ 1boy through pulls 17. The hinge 20 is limited from vertical displacements to the supports 21,

The extreme levers of 16 trolleys 1 and 3 (can be connected to them by means of a horizontal i22 horizontal transverse rod, which is connected to the lever 16 and the trolley frame via Spherical hinges 23 and 24, respectively.

Each two-axle bogie 1 or 3 is connected to the three-axle bogie 5 through its vertical hinge mechanism with the assistance of 1 1 double-arm lever 25 о. The middle point of this lever is the hinge 26. connected to support 8 of the three-axle bogie 5. Arm 25 hinge 27 and the hinge rod 28 is connected to the lever 9,

In the horizontal plane, each cart 1 or 3 is connected to the three-axle cart 5 through a horizontal articulated lever mechanism connected to the three-axle cart 5 by means of a two-arm lever 29, the midpoint of which by the hinge 30 is connected to the three-axle cart 5, and the extreme points are ball nirami 31 with transverse levers 32 which hinges 33 are connected with the levers 16. From the vertical displacements relative to the carriage 5, the rasiah 29 with the hinges 31 is limited by stops 34,

The operation of the hinged-lever mechanism is shown on the example of the vertical mechanism (Fig.9). The mechanism is in equilibrium if the moment of vertical P and horizontal Q forces are relative to the pin 13, acting on the lever 9 is equal to 0. In the course of passing the unevenness of the path at Р Pj, the levers 9 tend to turn to such a position when the condition P in Pa . . The same is true for the horizontal hinged-lever mechanism.
