SU10991A1 - Wheel with a removable rim for cars - Google Patents

Description

The present invention relates to a wheel with a removable rim for automobiles in which the rim is provided with tides or protrusions on the inner surface, and the spokes are made at the end with two springs with parts clamping the rims of the tides. Such wheels have so far been made in such a way that, to secure the rim, the spring clamping parts forming the fork were tightened with screws or the like, to free the rim parts, they were released by screwing the screws in the opposite direction, whereby the ends of the forks must be diverted under the action of the springback of the material and thus release the rim tides. Meanwhile, the ability of each material to spring down decreases with time, especially if, as is unavoidable with previously used structures, the material of the spring parts is all the time under stress. In this case, when loosening the screws, the forked ends of the spokes no longer diverge so that between them and with the rim slip there is a gap sufficient for turning and axial displacement of the rim, which causes the removal of the rim and the difficulty of removing the rim Such bolts are designed so that the spring-loaded clamping parts located at the ends of the spokes can, with the aid of these bolts, not only pull together, but also be separated, whereby the dimensions and relative position of the forked ends of the spokes and rilivov on the rim can be selectable so that a drive wheel for the finished material is not experienced stress. In FIG. 1 shows a section of the proposed wheel; FIG. 2 is a view along arrow A of FIG. one; FIG. 3-

 wheel cut with a different shape of the spokes FIG. 4 shows a section through a wheel with modified spring parts of the spokes.

Sleep; 1Y wheels (figs. 1-4) split by a slit l two co-optic parts L, i, equipped with HMM .i skushoi pressure surfaces, which correspond to the thrust surfaces on the projections with, from the inner side, the rim (/, designed for pneumatic machines

 and provided with a well-known image of a lateral ring-shaped lock and a securing ring. The head bolts supplied with the bolts are screwed into the cut / half of the rivet end of the spoke, and in the other half of L these bolts fit into the smooth part and, after installation, are fixed (to prevent the ring from falling out.) {Fig. 1-- 3). With this ring, on one side, and aaplechik / t, on the other, the bolt g P) and on both sides to the forked end of the spoke, so that when the bolt D is dragged to one side, the ends of the b, i) st when turning, when turned in the opposite direction, it is divorced.

The shoulder / bolt g enters the corresponding cut / tide c (Figs. 1 and 2), securing the rim against rotation in the direction of the ride. When the bolt g is screwed into the D hole by cutting / deep enough, shoulder K rests against the corresponding stop surface of the forked end L of both ends b, b are separated and the shoulder / enters the notch / (the position of the parts shown in Fig. 1). The rim is clamped and secured against rotation. If the bolt is now unscrewed, it will soon be thrust by the ring h into the outer surface of the forked end 6, after which both of the forked ends will be pulled out and the shoulder /

It will come out of the notch. As the rim is released, it can be removed after turning and axial displacement. :

In the embodiment shown in FIG. 4, clamping, the rim of the pro Is not worn out of the platy ends, but at their height of the gipaipi. The bolt is in this case performed by the skid of the golopka, and in return it is supplied with a nut W, which is screwed on after the bolt is installed and then fixed. Plots on it, for example, using a pin or pin. The shoulder /, protecting the rim from turning, is in this case placed between both forked ends and a cutout 1 in which this shoulder enters, is located on a ledge from the rim.

If the dimensions and the relative position of the fork ends and tides on the rim are chosen so that the material does not experience any tension, when the pressure surfaces of the fork ends touch the corresponding stop surfaces on the protrusions of the rim when fastening the rim, then further tightening of the bolt does not cause no significant mutual movement of the fork ends, but only increases the pressure and, thus, in the ready-for-ride wheel, the material does not undergo stress, being subjected to such in a short time only when the nozzle rim, and at the same time, g bolts are not subjected to shearing stresses, in the form of at .chem embodiment of Fig. 1-3 operate only in compression, and in the embodiment according to FIG. 4 - only for stretching.

The subject of the patent.

1. A wheel with a removable rim for automobiles, etc., in which the ends of the spiral consists of two clamps; 1x the rim of spring parts, characterized by the use of bolts that spread and tighten the ends of the spokes (Fig. 1-3), which the half of the b is inserted into the slot with the cut-out needle and its cut part i and the other half of the b with the smooth part, supported by the shoulder during wiring and the ring Lo when the ends of the spoke are tightened, and the shoulder is attached to

rim f / enters cut-out / protrusion with on rim and thus prevents the latter from turning.

2. Modification of the wheel described in paragraph 1, characterized in that when fastening the rim

by tightening the fork ends of the spokes, the bolt g is provided with a middle shoulder /, cutting / at one end, and cutting with a nut t at the other (Fig. 4). .
