Abstract
A traction saddle disposed on a tractor for connection with a traction pin of a trailer, is provided. The traction saddle includes a base, a gear set, and a damper. A gear carrier of the gear set fixes axial centers of the planetary gears of the gear set, the planetary gears are meshed with an inner ring gear of the gear set, and the inner ring gear is fixed to the base. The gear carrier is used for fixing the traction pin to rotate with the traction pin. The planetary gears are meshed with one end of a sun gear of the gear set to drive the sun gear to rotate, and the damper is connected to the other end of the sun gear to apply resistance to rotation of the sun gear. In addition, a traction pin, a tractor, a trailer, and a truck are also provided.
Claims18
A traction saddle disposed on a tractor for connection with a traction pin of a trailer, comprising:
- a base comprising an accommodating space;
- a gear set disposed in the accommodating space and comprising:
- an inner ring gear fixed to the base;
- a plurality of planetary gears meshed with the inner ring gear;
- a gear carrier fixing axial centers of the plurality of planetary gears, wherein the gear carrier is used for fixing the traction pin to rotate with the traction pin;
- and
- a sun gear comprising opposite first and second ends, wherein the plurality of planetary gears are meshed with the first end to drive the sun gear to rotate;
- and
- a damper connected to the second end to apply resistance to the rotation of the sun gear.
A traction pin disposed on a trailer for connection with a traction saddle of a tractor, wherein the traction saddle comprises a base, a gear set, and a damper, the gear set being connected between the base and the damper and comprising a gear carrier, and the traction pin comprises:
- a pin;
- and
- a connecting disc fixing the pin to rotate with the pin, wherein a disc surface of the connecting disc is perpendicular to the pin, and the connecting disc is used for being fixed on the gear carrier to receive resistance applied by the damper.
A tractor for connection with a trailer comprising a traction pin, comprising a traction saddle for connection with the traction pin, the traction saddle comprising:
- a base comprising an accommodating space;
- a gear set disposed in the accommodating space and comprising:
- an inner ring gear fixed to the base;
- a plurality of planetary gears meshed with the inner ring gear;
- a gear carrier fixing axial centers of the plurality of planetary gears, wherein the gear carrier is used for fixing the traction pin to rotate with the traction pin;
- and
- a sun gear comprising opposite first and second ends, wherein the plurality of planetary gears are meshed with the first end to drive the sun gear to rotate;
- and
- a damper connected to the second end to apply resistance to the rotation of the sun gear.
