<p>PROBLEM TO BE SOLVED: To provide a hub driving device in an improved form with a positioned hub support, a rotatable hub, an axial piston motor in a fluid static swash plate structure mounted on the hub driving device and put in driving contact directly with the hub and a brake connected directly between the hub support and the hub, having radial compact dimension, high output density and lower manufacturing cost. SOLUTION: The axial piston motor 3 has a cylinder block 14 supported at the outside and a motor shaft 17 connected in rotational synchronization with to the hub 2 and formed as a torque bar not subjected to lateral force. The hub 2 has bearing arrangements 4a, 4b independently supported by the hub support 1.</p> |
