Description

"Qorät sun Auf and .Ujsiohen of. Zaiirseu gripping open!

3rd honor »

The "price increase" concerns a device for pulling on and off from vehicle tires to wheel rims with a holding device for the rim and a mounting tool that can be rotated around the I-rim axis 3ie consists in 'that the holding device as one by a relative movement between it and the rim to be operated clamping wedge coupling is formed. The relative movement between the rim and the holding device is expediently achieved by the arcuate movement of the assembly tool brought about.

The new G-device has the particular advantage that the Clamping a rim on the device takes place practically automatically without any special effort on the part of the operator.

".Viii one with the automatic plague tension of an? Elge also at the same time an automatic centering of this rim achieve compared to the assembly tool, it is advantageous that the clamping wedge coupling is at least three in "equal mutual distances act against the inner surface of the ielgen ^ IClemmelemsnte has

It is useful if the clamping elements of the Clamping wedge coupling consist of clamping levers which are eccentric ^ are hinged to the rock support and are at the relative

rotation

rotation of the assembly tool against the? elge against its Create inner wall.

The “oil” version of the price increase consists in the fact that the clamping elements of the clamping Zeilkupplung consist of a number of eccentric notes, which are mounted on the rim carrier at regular intervals and which are placed against the inner wall of the rim when the assembly tool rotates relative to the rim.

A favorable mode of operation of the new device with a very simple construction can be achieved if the clamping elements of the clamping wedge coupling from a number consist of clamping disks, which are evenly spaced in longitudinal slots that run at an acute angle to the inner surface of the rim carrier are displaceably mounted and 'during the selective rotation of the mounting tool with respect to the Place the rim against its inner wall.

Another embodiment of the new device is; that the clamping elements of the clamping cable coupling consist of a number of rolling elements which are spaced evenly apart from the I ^? inside flat and at an acute angle. this one on the I? elgentr ^; iger arranged abutments lie and when the relative rotation of the mounting tool against the relge create against the inner wall. r _;

It is advantageous if the common "handle in the shoe position is in a locking detent, preferably on the skin carrier" and under the action of the clamping elements in

In the drawing there are some examples Embodiments of the innovation schematize *! shown.

According to Hg. 1, a support plate 2 is provided on the upper end of a column-like frame 1 for a wheel rim 3 to be attached to it carries removable mounting tool 5 and has a worm wheel 6 on its end located below the plate. A worm 8 to be driven by a motor 7 engages in this · A foot switch 9 is used to switch the ilotor 7 on and off ·

On the support plate 2, three are applied to the inner surface of one on it at equal mutual distances Wheel rim acting Kleiamelemente provided.

These can be like this. 2 shows in a top view that there are three Slesm levers 10, each with a bolt 11 are articulated eccentrically on the support plate 2 and in their rest position under the action of a tension spring 12 on one corresponding stop 13 is in contact *

With the mounting tool 5 removed and the XlemahebeiilQ in the rest position, a wheel rim 3 is placed on the support plate 2 and then the tool 5 _{r is placed} back on the flattened end of the lelle 4-. Danaqh, the clamping levers 10 are pivoted about their pivot pins 11 and thereby removed from their stops 13 until the springs 12 fix the levers 10 after the pivot pins 11 have been exceeded. . Place against the inner edge of the rim · By switching on the motor by means of the foot lever 9 we & the shaft 4 via the worm gear

drives 8,6 and thus also the assembly tool 5 in one of the £ lemmhebelii 10 rotated in the opposite direction. First of all, as a result of the av / ical the tool on the one hand and the jester with helping on the other hand Frictional movement the latter taken along a little in the same direction of rotation until the lever 10 is sufficiently on the inner rim of the rim have jammed and thus prevent further rotation while the tool continues to move up to a full turn will. As a result of this movement of the tool 5, with simultaneous centering of the rim to the 7 / tool shaft the broad point bearing either a heating applied to the rim 3 or deducted from it.

When the tool comes to a standstill, it is removed from its shaft 4 upwards again. Ss then suffices with Moving the rim back in the opposite direction of rotation so that it is unhindered by only a small expenditure of force to be able to remove the support plate 2. Then the clamping levers 10 are moved back into their rest position to a other I? elge to be able to edit ..

The size of the contact pressure of the clamping lever 10 on the inner edge of an applied rim is therefore dependent on the force of the self between the tool 5 and. Fig / tire dependent on the circulation, so that under all operating conditions, such as are given by the application and removal of new and used soaps, the corresponding pressure is always automatically set ""

In the embodiment of the innovation according to fig. 3 instead of the clamping levers, eccentric disks 14 mounted at regular intervals on 4, support plate 2 are provided. Di ^ e, preferably at its edge to increase the friction system- * delt'en disks can be rotated about a bolt 15 each under the action of a flat spring 16, which they in the

system

Hold the system with the inner edge of an applied? Elge 3. Work and activity v / eias i ,, t the same as those described above Construction.

j-ig. 4 the IClssmkail-Xupplun ^ s consist of one Looked! of ELesaaacaeiben 17 »those at regular intervals in longitudinal slots running at an acute angle to the inner surface 18 of the support plate 2 are mounted displaceably by means of pivot pins 19 · With a relative rotation of the mounting tool 5 opposite an? Elge 3 lay in the slots IS

outwardly conquering discs firmly against the inner edge of the skin

and thereby hold the skin tight. The I-rehfoolsen 13 of all Washers 1? are through a common sliad 20 coupled with one another with an outwardly protruding handle 21 is provided «Bas link 20 is under the effect one of the legs 22 pulling the open shafts 17 into the sleeve position, drive :, its handle 21 in the rest position of the discs in an operrast 23 is on the! support plate 2.

Bs can therefore be done with a single movement of the hand all of the small elements together in their work or »in be brought to their rest position.

In Pig. Finally, 5 is another embodiment the control shown in which the iClemmelemente of the Slenna-Sc-illmp-Glunfr from a number of scaeibsnförniigenilbviglz- ϊ Bodies 24 consist of the elements of a field company area and one in the pointed V / angle su this attached to the Iragplatte 2 vViüerlager 25 exist. Also in this version-; form are all clamping elements by a common, unljer Peder "irlcung standing and with his handle in a last" de * Iragplatte 2 to be introduced actuator 26 connected to one another.
