Abstract
A steering spindle arrangement includes a spindle bolt (2), an axle beam (1) that is secured to a central part (2b) of the spindle bolt (2), a stub axle (5) that has a first arm (6) that is rotatable around a first part (2a) of the spindle bolt (2) via a first bearing (11) and a second arm (8) that is rotatably arranged around a second part (2c) of the spindle bolt (2) via a second bearing (22). An adjusting mechanism (4, 18) makes it possible to adjust a variable rotation resistance for the stub axle (5) when it is rotated around the spindle bolt (2).
Claims8
A steering spindle arrangement comprising:
- a spindle bolt having a central part;
- a first part and a second part between which the central part is disposed;
- an axle beam secured to the central part of the spindle bolt;
- a stub axle having:
- a first arm that is rotatable around the first part of the spindle bolt via a first bearing;
- the stub axle having a second arm that is rotatable around the second part of the spindle bolt via a second bearing;
- an adjusting mechanism configured to adjust a variable rotational resistance for the stub axle when the stub axle is rotated around the spindle bolt;
- and
- the adjusting mechanism comprises a sliding bearing between the stub axle and the axle beam, a tensioning device configured and operable to generate an adjustable force that presses the stub axle and the axle beam from opposite sides of the sliding bearing for causing the stub axle to acquire a selected resistance when the stub axle is rotated around the spindle bolt, wherein the sliding bearing has a first sliding surface in contact with the stub axle, and has a second sliding surface in contact with a contact surface of the axle beam.
A steering spindle arrangement according to claim 7, further comprising the roller bearing includes an inner ring configured and operable to contact the nut and to contact an outer ring of the bearing;
- and
- a bearing seat in a first arm of the stub axle that bears on the outer ring of the bearing.
