SU40405A1 - Centering device for coupling devices on the foot - Google Patents

Description

The invention relates to devices centering at the time of adhesion automatic coupling devices of rolling stock by means of spring-loaded rods fixed in the frame of the car and abutting from the sides into the shank of the coupling device.

In the proposed arrangement, the said rods, in order to facilitate centering in the horizontal direction, are provided at the ends with rollers rolling along the grooves in the socket mounted on the hitch of the coupling device, and providing centering hitch also in the vertical direction.

In FIG. 1 shows a front view, in partial section, of the proposed device, and FIG. 2 is a top view of it, also with a cut in one half.

The main part of the proposed fixture is a socket /, freely put on the shank 15 of the automatic coupling device. Between the socket and the buffer bar 14, the frame 2 is tightly attached to the latter, the purpose of which is to perceive the force received by the socket from

HEADS of the coupling device and transfer it to the buffer bar, protecting it from concentrated impact. The centering rods 4 with equivalent springs 3, located on both sides of the sockets, have plugs 5 at the ends, in which rollers 8 are rotatable on axes 7. Each of these rollers has a flange 9 in the middle of its cylindrical surface that freely enters the groove 10 of the corresponding side of the rosette 7. Such a deep contact between the latter and the rollers 8 on both sides is necessary for the centering, in view of the free attachment of the socket / to the automatic coupling 15 shank. The ends of the plugs 5, which cover the socket / on both sides, must also prevent its significant slipping along the shank 15 of the automatic coupler towards its head. In order to receive the compression forces from the rods 4 from the coil springs 3, there are retaining plates // freely put on. 6 round rods and abutting the rear of the ledge when the rectangular cross section of the rod 4 is transferred to the round one. In order to allow longitudinal movement of the rods 4, they are mounted in rectangular holes in the tides 12 of the frame 2 and in circular holes in the sleeves 13, which
