Hydrostatic slewing drive

A hydrostatic slewing drive comprising:

• a housing;
• an intergral pinion shaft and rotating cylinder block having borings that is rotationally mounted in the housing;
• a slewing pinion connected to the pinion shaft and rotating cylinder block;
• an axial piston motor that utilizes a swashplate in the housing, the axial piston motor having pistons located in the borings of the rotating cylinder block and pinion shaft;
• and
• a brake that can be effectively connected with the pinion shaft and rotating cylinder block, wherein the brake is located next to a swashplate base and is synchronously connected by a torsion rod housing with the pinion shaft and rotating cylinder block.

A hydrostatic slewing drive comprising:

• a housing;
• an intergral pinion shaft and rotating cylinder block having borings that is rationally mounted in the housing;
• a slewing pinion connected to the pinion shaft and rotating cylinder block;
• an axial piston motor that utilizes a swashplate in the, the axial piston motor having pistons located in the borings of the rotating cylinder block and pinion shaft;
• and
• at least one valve between the swashplate and the swashplate base.
