The invention relates to the field of trailer devices, and provides a trailer traction control device and a trailer traction system. The trailer is dragged by the tractor towing device, and the trailer traction control device controls the steering freedom degree of the trailer. The trailer traction control device comprises a fixing seat and an ejector rod, the fixing seat is suitable for being installed on a trailer, and the fixing seat comprises a clamping part with a clamping groove; the ejector rod comprises a mounting end and an abutting end, and the mounting end is suitable for being mounted on a towing vehicle towing device; the abutting end faces the trailer and is matched with the clamping groove. The trailer traction system comprises a tractor, a trailer and a trailer traction control device. According to the trailer traction control device and the trailer traction system, the trailer traction control device can release the steering freedom degree of the trailer, and a tractor towing device can conveniently pull the trailer to achieve turning and steering actions; and meanwhile, the steering freedom degree of the trailer can be locked in the retreating process of the trailer, so that the trailer loses the steering freedom degree, and the tractor towing device can conveniently pull the trailer to achieve the linear reversing action.

    本发明涉及拖挂车装置领域,提供一种拖车牵引控制装置及拖车牵引系统。拖车由牵引车拖挂装置牵引,拖车牵引控制装置控制拖车的转向自由度。拖车牵引控制装置包括固定座和顶杆,固定座适于安装于拖车,固定座包括具有卡接槽的卡接部;顶杆包括安装端和抵接端,安装端适于安装于牵引车拖挂装置;抵接端朝向拖车并与卡接槽相匹配。拖车牵引系统包括牵引车、拖车以及拖车牵引控制装置。本发明的一种拖车牵引控制装置及拖车牵引系统,拖车牵引控制装置能够释放拖车的转向自由度,便于牵引车拖挂装置牵引拖车实现转弯转向动作;同时还能在拖车后退过程中锁定拖车的转向自由度,使得拖车失去转向自由度,便于牵引车拖挂装置牵引拖车实现直线倒车动作。
