摘要 |
The axle pieces (10) have a downwardly directed axle section (15) for application of a steering roller (20) provided with a pivot bearing (320). At least one securing device (40) is provided, which secures the steering roller on the axle piece. The cross-section of the basic shape of the fixture section (11) is larger than the cross-section (16) of the basic shape of the axle section (15). The pivot bearing (30) of one of each steering roller (20) either is formed as a grooved ball bearing (31) or as a roller bearing. With spot welding of the axle pieces to the chassis (3), the spacing of the welding points (9) is greater than the diameter of the axle section.
