摘要： The invention relates to a towing device for motor vehicles, in particular for passenger vehicles, which comprises a receiving part attachable to the rear of the motor vehicle, a ball collar on which a coupling ball is mounted and which can be connected to the receiving part, and attachment means which can be used to attach the ball collar to the receiving part in a detachable manner. The object of the invention is to improve said towing device in such a manner that it has as stable a structure as possible. Said object is attained in that the receiving part is in the form of a receiving sleeve (24), the ball collar (14) is provided with an end section (22) insertable into the receiving sleeve (24) in a direction (52) of insertion, the receiving sleeve (24) and the ball collar (14) are provided with co-operating positively engaging elements (42, 44, 46, 48) which can be engaged by the movement in the direction (52) of insertion and form in said position for the ball collar in the direction (52) of insertion a stop and a second transverse guide, and the attachment means (60) when locked holds the positively engaged elements (42, 44, 46, 48) in position with a force component parallel to the direction (52) of insertion.
摘要翻译：用于机动车辆的牵引装置技术领域本发明涉及一种用于机动车辆，特别是用于乘用车辆的牵引装置，该牵引装置包括可附接到机动车辆的后部的接收部件，其上安装有耦合球的球领，并且该球领可以连接到接收部件以及可用于将球领以可拆卸的方式附接到接收部的附接装置。本发明的目的是改进所述牵引装置，使其具有尽可能稳定的结构。所述目的通过以下方式实现，即接收部件为接收套筒（24）的形式，球圈（14）设置有能够沿方向（52）插入接收套筒（24）中的端部部分（22），接纳套筒（24）和球领（14）设置有配合的主动接合元件（42,44,46,48），所述配合主动接合元件能够通过沿插入方向（52）的运动而接合，并且在插入止挡件和第二横向导向件的方向（52）上形成用于球领的所述位置，并且附接装置（60）在被锁定时将强制接合元件（42,44,46,48）保持在平行于插入方向（52）的力分量。
