Abstract
Spindle arrangement for a non-driven, steerable vehicle wheel of a motor vehicle including a spindle unit (10) with bores (11) located at an axial distance from one another and aligned axially with one another for rotatable mounting of the spindle unit (10) relative to a kingpin (4; 4′) accommodated via a central portion (5) in a through-bore (3) in a front axle-beam (2). A stub axle unit (18) is connected to the spindle unit (10) and on which a wheel hub (19) is mounted. Bearing means (8, 9) for the rotatable mounting of the spindle unit (10) are arranged at a first and second end (6, 7; 6′, 7) of the kingpin (4; 4′). When the bearing means (8) located at the first end (6; 6′) of the kingpin (4; 4′) is a spherical sliding bearing (8), that bearing (8) takes up only radial forces in relation to the center axis (12) of the kingpin (4; 4′).
Claims12
A spindle arrangement for a non-driven, steerable vehicle wheel for motor vehicles, said spindle arrangement comprising:
- a spindle unit (10) which is rotatably mounted relative to a kingpin (4,4′) accommodated in a front axle-beam (2), a stub axle unit (18) which is connected to said spindle unit (10) and on which a wheel hub (19) is mounted, and, arranged at a first end (6, 6′) and a second end (7, 7′) of said kingpin (4, 4′), bearing means (8, 9) for rotatable mounting of said spindle unit (10), said bearing means (8) at said first end (6, 6′) of said kingpin (4, 4′) is a spherical sliding bearing (8);
- and
- said spindle unit (10) is provided with bores (11), located at an axial distance from one another and aligned axially with one another, in which bores (11) said kingpin (4, 4′) is mounted in said bores by said bearing means (8, 9);
- said kingpin (4, 4′) is provided with a conical central portion (5) which interact with a conical through-bore (3) in said front axle-beam (2);
- and
- said kingpin (4, 4′) is oriented in relation to said spindle unit (10) so that said spherical sliding bearing (8) takes up only radial forces in relation to the center axis (12) of said kingpin (4, 4′).
A spindle arrangement for a non-driven, steerable wheel of a motor vehicles, said arrangement comprising:
- a spindle unit including a kingpin rotatably mounted in a receiving through-bore, said kingpin having first and second ends, each of which is associated with one of two bearing assemblies that facilitate rotatable motion of the kingpin in the through-bore;
- said through-bore being predominantly frusto-conically interiorly shaped and said kingpin being predominantly frusto-conically exteriorly shaped and configured for complimentary reception in said through-bore;
- a pair of bores, one each at substantially opposite ends of said through-bore with one of said bearing assemblies positioned within each of said bores;
- and
- a first of said bearing assemblies being a spherical sliding bearing configured to exclusively take up radial forces relative to a center axis of said kingpin.
