An axle-to-beam connection for a vehicle axle/suspension system includes an axle having at least one depression formed therein. A sleeve is formed with at least one depression and disposed about the axle so that the axle depression and the sleeve depression matingly engage one another to form a mated pair of depressions. A method of forming the axle-to-beam connection includes providing an axle and disposing a sleeve about the axle. At least one mated pair of depressions is simultaneously formed in the axle and the sleeve. The sleeve is immovably mounted to a vehicle axle/suspension system.

A wheel supporting device includes: a hub unit (2) that has a rotary ring (11) having a first spline (25) on its axially inner end face (24); and a joint (3) that has an outer ring (32) having a second spline (38), meshing with the first spline (25), on its axially outer end face (37). At least one projection (51) included in a plurality of projections (50) of the first spline (25) projects in the axial direction by a larger amount than the remaining projections (50) of the first spline (25). When a crest (52) of the at least one projection (51) contacts a crest of one of projections (39) of the second spline (38), a play is caused between the rotary ring (11)and the outer ring (32) due to the at least one projection (51) that works as a fulcrum.

Die Erfindung betrifft eine Starrachsenanordnung in einem Fahrzeug, insbesondere in einem Nutzfahrzeug, mit einer Starrachse, die einen in Fahrzeugquerrichtung verlaufenden Achskörper aufweist, von dem eine Befestigungskonsole für einen Mehrpunktlenker nach oben abragt, wobei der Mehrpunktlenker mit seinen Lenkerarmen einerseits an einem, in Fahrzeughochachsenrichtung gesehen, beabstandet oberhalb des Achskörpers liegenden konsolenseitigen Mehrpunktlenker-Anbindungsbereich der Befestigungskonsole und andererseits an einem Rahmen des Fahrzeugs mittelbar oder unmittelbar gelenkig angebunden ist. Erfindungsgemäß ist der konsolenseitige Mehrpunktlenker-Anbindungsbereich (12) beabstandet oberhalb eines, bezogen auf die Längserstreckungsrichtung des Achskörpers (2), Längsmittenbereichs (9) des Achskörpers (2) angeordnet, wobei von dem konsolenseitigen Mehrpunktlenker-Anbindungsbereich (12) ausgehend jeweils wenigstens ein Konsolenarm (18, 19) nach unten zum Achskörper (2) geführt und dort auf gegenüberliegenden Seiten des Längsmittenbereichs (9) des Achskörpers (2) an diesem angebunden ist.

A fastening system (1) for fastening an auxiliary wheel (2) to a main wheel (3) of an agricultural vehicle comprises an annular spacer (18) interposed between a rim (4) of the main wheel (3) and a further rim (17) of the auxiliary wheel (2), and a plurality of tensioning devices (33) acting between the auxiliary wheel (2) and the main wheel (3), for holding the auxiliary wheel (2) pressed against the main wheel (3). In order to reduce the stress to which a disc (5) of the main wheel (3) is subjected, a fastening element (24), or auxiliary disc, is provided comprising a first fastening portion (25), which can be detachably fixed to a hub (6) of the vehicle and a second fastening portion (28), which is axially spaced from the first fastening portion (25), wherein each of the tensioning devices (33) comprises a first end element (34) that can be detachably fastened to the second fastening portion (28) and a second end element (36) that can be detachably fastened to the annular spacer (18).
摘要:
One object of the present invention is to provide a wheel bearing apparatus which can suppress the hoop stress of the inner ring caused by the caulking process and reduce the bearing friction with suppressing the clearance range after caulking. According to the present invention, there is provided a wheel bearing apparatus comprising an outer member integrally formed on its outer circumference with a body mounting flange and on its inner circumference with double row outer raceway surfaces; an inner member including a hub wheel and an inner ring, the hub wheel being integrally formed on its one end with a wheel mounting flange and on its outer circumference with one inner raceway surface opposing to one of the outer raceway surfaces and having a cylindrical portion axially extending from the inner raceway surface through a stepped portion, the inner ring being formed on its outer circumference respectively with the other inner raceway surface opposing to the other of the double row outer raceway surfaces; double row rolling elements rollably contained between the inner raceway surfaces of the inner member and the outer raceway surfaces of the outer member; and the inner ring being axially immovably secured on the hub wheel by a caulking portion formed by plastically deforming radially outward an end of the cylindrical portion of the hub wheel characterized in that the thickness of a smaller end surface of the inner ring is larger than the height of the stepped portion of the hub wheel; and that the axial position of the smaller end surface of the inner ring is set within an axial range between the axial position of the outermost-side point of the inner-side rolling elements of the double row rolling elements and the axial position of the groove bottom point of the inner raceway surface of the inner ring.
