Claims (4)

1 2 rolling bearing rotatable about a vertical axis wheel patent claims: carrier and an impeller mounted on it in the direction of travel behind this ^ axis. 1. Chassis for a chassis known from e-nW on its underside with this household appliance provided on a sliding shoe, such as 5 (USA Patent 3 003 179), the nui encloses a vacuum cleaner, a polishing machine or diil .. at its leg ends to in The Nane of the AuIIa consists of a Gkitsclur reaching down in the center of the sliding shoe level of the impeller. arranged and arranged by means of a roller bearing around U-shaped a on the housing -.- bottom of the household: yerakeiiie vertical axis rotatable Radträaer and arranged axial ball bearing, on whose lines' one in the direction of travel behind this axis io running ring a the relatively large Lauirad l; _: - i-illuminated impeller. thereby i> eke η η - like fork eccentric to the axis of rotation of the ball I .: shows that the device-side running groove (6) is attached. Apart from the fact that this results in a known manner with a »large overall height of the impeller bearing at the jam! Ren Durehmesser than the impeller (1) auseebilde- sucker housing and thus also the sliding shoe .. ic: i and the axis (17) of the impeller (I) "at least 15 containing a strong one-sided load at least approximately in the rolling plane Axial ball bearing results in the latter being able to pivot from the radially inwardly curved upper edge of a circularly unprotected roller bearing, which is practically curved inwardly around the entry of dirt and textile fibers Impeller without the upward-facing ring wall and holding device when pulling across the ground to tilt the other ring (S) of which with one in the, frequent maintenance and cleaning ring wall of the sliding shoe-inserted ring collar. gen provided, shoulder-shaped in the form of a retracted edge part of a side piece and the like (USA.-Patent 1 743 255) with a dome-shaped bulge (15) for the 35 it is also already known that as Angular contact ball bearings barrel 1 ad (1) and with downwardly designed swivel bearings with a larger in-bearing lugs (3) for its axis (17) versehe- ndiameter than the outer diameter of the NEN circular plate (4} are formed, with the two running wheels and the latter within Derden races (5, 6) with the one between them like a housing upwardly extended lower Laufgeschlosstnen rollers (2) <! arch one at the 30 of the pivot bearing ring to be arranged. It is the top of the Krcisplatte (4) fixed, the around the axis of the impeller at least approximately in the curved upper edge of the ring and of the sliding and only slightly higher than the rolling plane of the shoe overlapping cover plate tte (8) together of the pivot bearing, and its upper race are not held, and that the bearing gap between engages the lower race for the purpose of the ring collar on the circular plate (4) and the holding together of the parts with an inwardly-ring wall of the slide shoe (7) below the dead ring flange. Even if this storage for the roller bearing (2) is closed by a seal, part of a recess open at the bottom is in the. Piece of furniture is included, it is missing here 2. Chassis according to claim 1, characterized on a sliding shoe, for which, because of the comparative characterizes, that the seal consists of a movement of furniture in the Ge ring wall, which is rare in the 4 ° used and the sliding shoe (7) in contrast to household appliances also no need bezum To continue the center of its recess. Furthermore, the sealing of the pivot bearing the metal ring (4) and one against which the lower race encompasses sen, on the edge part of the circular plate (4) flange on the upper race inadequate what attached sealing ring (11) consists. 45 also for the intended use 3. Running gear according to claim 2, characterized in that this storage is of no practical importance. indicates that the sealing ring (11) from Furthermore, it is already known (USA.-Patent two parts (12, 13) glued together, 2 972 162), spherical rollers in one is made, of which the one part (12) from them receiving housing below the upper Kueinem Material with a relatively large 5 ° special gel support by a circumferential ball Volume, such as a foam-catching horizontal ring seal to be sealed, consists. such an immediate seal 4.

In contrast, the invention has the task based on creating a chassis of the type mentioned, in which the height distance between The invention relates to a chassis for a housing bottom on both sides and the upper part to be machined Underside with a sliding shoe 65 area is kept low and in which the roller bearing Household appliance such as a vacuum cleaner, a floor polisher, effective against the entry of dirt and textile machinery Od.
