A hub-bearing assembly serves to rotatably mount a soil-working disc (D) on a supporting axle (A) of an agricultural machine. The assembly comprises a hub-bearing unit () and a sealing device (). The a hub-bearing unit has a radially outer, rotatable outer race () from one side of which a flange () radially extends for mounting a disc (D). The sealing device () is mounted on a side of the hub-bearing unit opposite to the side of the flange (). The radially outer surface of the assembly has a portion () intermediate the flange () and the side of the sealing device (), which is radially recessed so as to serve as a preferential seat for winding wires picked up from the fields during use of the agricultural machine.

Hub-bearing assembly for soil-working discs

One end of a resilient sleeve is fitted on a tubular projection of the bell of a constant velocity joint. The sleeve covers a radial slot formed in the projections and the arms of a spring locking ring for axially removably securing the joint bell to a toothed driving ring fixed on a rotatable hub. The other end of the sleeve has a radially inwardly projecting flange which is sealingly axially clamped against a rigid annular part secured to or integral with the hub.

Sealing arrangement between a constant velocity joint and a hub bearing unit of a motor vehicle wheel

A constant velocity joint has an outer bell telescopically coupled for rotation with a rotatable hub of a hub bearing unit so as to provide torque transmission thereto. The joint bell is releasably axially coupled to a rotatable member of the hub bearing unit by an annular connector. The connector includes a radially inwardly extending annular flange axially clamped against a rigid annular part fixed to or integral with the hub, and a radially outer portion extending axially around a cylindrical surface of the joint bell. This outer portion has a resiliently radially expansible section with one or more radially inwardly extending protrusions providing a snap connection with a relief or recess formed on the cylindrical outer surface of the joint.
