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 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 a sun gear of the gear set to drive the sun gear to rotate, and the damper is connected to the sun gear to apply resistance. In addition, a traction pin, a tractor, a trailer, and a truck are also provided.
