Low-damage automatic vehicle hauling device for road traffic

Abstract

The invention relates to the technical field of vehicle hauling, and in particular to a low-damage automatic vehicle hauling device for road traffic. The device comprises an upper fixed leg; the bottom end of the upper fixed leg is in threaded connection with a lower fixed leg; the outside bottom end of the upper fixed leg is in hinge connection with a first fixed mount and a second fixed mount; the outside top end of the lower fixed leg is in hinge connection with a third fixed mount and a fourth fixed mount; a first hydraulic rod and a second hydraulic rod are arranged at the bottom of the upper fixed leg; the left end surface of the first hydraulic rod is fixedly connected with the third fixed mount; the right end surface of the first hydraulic rod is fixedly connected with the second fixed mount; and the left end surface of the second hydraulic rod is fixedly connected with the first fixed mount. Through the first hydraulic rod and the second hydraulic rod, different wheel treads can be adjusted through stretching of the hydraulic rods, so that a support function is provided, and the phenomenon that the hauling effects for the vehicles with different sizes are different is avoided.

Description

technical field [0001] The invention relates to the technical field of vehicle hauling, in particular to a low-damage automatic towing device for road traffic. Background technique [0002] A trailer is a kind of vehicle used to haul a car. It consists of a chassis, a lifting device, a lifting device, a hydraulic system, an electronic control system, a car body and a toolbox, etc. It has the functions of lifting, pulling and lifting traction. It is suitable for clearing obstacles on highways and urban roads. With the development and progress of society, the number of cars is increasing sharply. Therefore, the maintenance and hauling of cars and illegal hauling are also increasing. Due to The traditional towing device has non-negligible damage to the hauling of the car itself, and has been complained and dissatisfied by many customers. Therefore, there is an increasing demand for a low-damage automatic towing device for road traffic. [0003] At present, the trailer devices ...

AI Technical Summary

Problems solved by technology

[0003] At present, the trailer devices on the market have many hazards to the car itself. Using the method of lifting the trailer can easily damage the bottom structure of the car and cause serious damage to the protruding parts at the bottom of the car. The lifting trailer device is due to the weight of the car body Concentrating on a certain part increases the load on the lifting contact position, which easily deforms the car body. When the lifting force is placed on the wheels in time, it will also generate a torsion force on the wheels, which seriously threatens the safety of the car's components. The trailer concentrates the force on one point, which poses the greatest threat to the safety of the car's components. Therefore, a low-damage automatic trailer device for road traffic is proposed to solve the above problems.
