摘要： A steering axle for a steerable vehicle includes an axle housing, a steering motor, a steering gear, a first steering knuckle with a first steering arm, a second steering knuckle with a second steering arm, a coupling rod, a first tie rod, and a second tie rod. The first and second steering arms are each rigidly arranged on a respective steering knuckle that is hinged in the axle housing. The first and second tie rods are each hinged at a first end to a respective steering arm and hinged at a second end to the coupling rod. The steering axle is configured so that the steering motor can set a steering angle of the steering axle via the steering gear. The steering axle has first and second intermediate steering levers, each hinged at its first end to the axle body and hinged at its second end to the coupling rod.

摘要： A steering drive for a steering axle of a steerable vehicle includes an electric motor with a motor shaft. A steering lever is rotatable about a pivot axis that is parallel to the electric motor. First and second planetary stages each have a sun gear, planet gears, and a planet carrier. The steering drive is configured such that a force flow runs from the first sun gear via the first planet gears to the first planet carrier. The force flow furthermore runs via the second sun gear and via the second planet gears to the second planet carrier, and furthermore runs to the steering lever. The steering drive has a spur gear stage and is configured such that a force flow from the motor shaft to the first sun gear runs via the spur gear stage. Also disclosed is a steering axle and an industrial truck.

摘要： A drive (1) for a steering axle (26) of an industrial truck includes two steering arms (11, 12), an axle arch (8), a tie rod (13) configured as a spindle (13), a spindle nut (7) fixed axially on the tie rod (13), and a gear stage (21). Adjustment of the steering arms (11, 12) can be effected by axial displacement of the tie rod (13), and by the spindle nut (7) being able to be driven by a drive output element (7) of the gear stage (21). The drive (1) has two mutually coaxial electric motors (17, 18) disposed parallel to the tie rod (13). A drive element (14) of the gear stage (21) can be driven by the two electric motors (17, 18), which are disposed so as to be axially centric between the two electric motors (17, 18). Also disclosed is a steering axle and an industrial truck.
