SU36828A1 - Device for strengthening the ends of the springs on the frame of carts - Google Patents

Description

In the proposed device, to reinforce the ends of the springs on the carriage brine, the bolt passed through the frame beam and the eye of the spring is made with a removable head so that it can be removed without the nut completely unscrewing. This bolt on the side of the head ends with a flange, the diameter of which is less than the diameter of the holes in the frame beam and the eye of the spring, and also less than the diameter of the hole of the washer placed between the frame and the detachable head. The latter has the form of a washer with a radial notch that encloses the bolt, and, moreover, is provided with a concentric protrusion that falls inward into the washer adjacent to it when the bolt is tightened.

On the schematic drawing / figure 1 depicts a side view of the Koytsa, spring; FIG. 2 - its top view; FIG. 3 and 3 are a view of the removable head from the end and in section, and FIG. 4 and 4-such w§ view washers.

In the proposed device for Strengthening the end of the spring 12 on the frame K T1 EXTENDING bolt 1, passing through the hole in the frame beam 18 and in the eyelet 1: 7 res (173)

The trash has no fixed head, but is equipped with a flange 4 at the end, which passes freely through the hole in the frame beam and the spring eye. The head 2 of the bolt itself is made removable in the form of a washer with a radial cut-out (Fig. 3) and is put on the bolt 1, before tightening it, between the flange 4 and the washer 3 adjacent to the frame beam 18. The hole in the washer 3 whose diameter larger than the diameter of the flange 4, has a conical surface (Fig. 4). The "rum of the bolt I" enters this hole when tightening the last one, the redcentric protrusion located on the head 2 (Fig. 3). Since the flange 4 doesn’t pass through the slot of the head 2 in size, when the bolt 1 is tightened, a small rotation of the nut is sufficient so that the protrusion of the head 2 is sunk into the washer 3 and the end of the spring is fixed. In order to remove the spring, it is enough to slightly unscrew the nuts of the bolts 1 fixing the ends of the spring by about 5 mm, reset the removable heads 2 and push the bolts 1 with nuts out of the holes in the beams of the frame 18, ears 17 of the spring and washers 3 .

The subject matter of the invention.

1. The device for strengthening the ends of the referral on the frame of the carts with the use of a bolt through the frame beam and the eye of the spring; characterized in that, in order to remove the bolt without fully unscrewing the nut, the bolt head of the bolt is removable.

2, The form of the device according to P. T, which is removable so that it is removable

The head 2 has the form of a washer fitted with a radial cut-out covering the flange on the inner side of the flange, and 4, and a concentric protrusion falling inside the washer 3 (Fig. 3) when tightening the bdd ..;,.

3, the form of the device according to paragraphs. 1 and 2, differently, 4to the diameter of the flange 4 is smaller than the diameter of the hole; the washers 3, the frame beams and the spring eye.,
