Description

A car towing device for a car

technical field

The utility model relates to a traction device, in particular to a traction device installed at the rear of a car and used for traction of a caravan.

Background technique

The towing device of the caravan in the prior art is not firm enough in structure, its traction bearing capacity is relatively poor, and the connection form basically adopts a soft connection, so it is very easy to cause the caravan to be damaged due to sudden braking and other reasons during the towing process. It will cause damage to the rear of the car, so it is not suitable for towing a caravan. In addition, even if a rigid connection is used, in order to improve the carrying capacity of the existing tow hooks, the arrangement position of the tow hooks on the anti-collision beam is not in the middle, but on the left or right of the anti-collision beam , This will cause the caravan to turn to the left or right due to the inertial force during the driving process, causing unsafe hidden dangers. In addition, during the high-speed driving process, the existing traction device is not strong enough to withstand the impact of the caravan.
