An adjustable wheelbase trailer frame and its working method

Abstract

A trailer frame that can adjust the wheel base, comprising a wheel guide plate, a wheel stop plate is connected to the rear of the wheel guide plate, the wheel guide plate includes two independent inclined wheelways, and each inclined wheelway Protruding connectors are respectively provided at the rear of the wheel stop plate, and a plurality of concave connectors are arranged transversely on the front part of the wheel stop plate, and a first rectangular connecting hole is hollowed out on the protruding connectors. A second rectangular connecting hole is hollowed out on the concave connector, and the first rectangular connecting hole and the second rectangular connecting hole are connected by a rectangular pin; the present invention can select and adjust the center of the trailer frame according to the wheelbase of different wheels. The distance between the inclined wheelways makes it suitable for a variety of vehicle types, and the adjustment is convenient and quick; the invention also uses rectangular pins to connect the wheel guide plate and the wheel stop plate, and can be reinforced laterally to prevent the deformation of the wheels on the trailer board , thus affecting the smoothness of the trailer.

Description

technical field [0001] The invention relates to a trailer frame capable of adjusting wheelbase and a working method thereof, belonging to the technical field of trailer tools. Background technique [0002] As the number of urban vehicles continues to increase, vehicle congestion is serious, and urban parking troubles are aggravated. In addition, people's pace of life is accelerating. Drivers are prone to temporarily park vehicles in places that are not suitable for parking due to emergencies, thus causing traffic jams and hindering the normal walking of pedestrians. Or hinder public evacuation, seriously affect people's normal life, and cause safety hazards. [0003] For this reason, in the technical field, a trailer is often used for directional removal of the vehicle, wherein the trailer is composed of a chassis, a lifting device, a lifting traction device, a hydraulic system, an electric control system, a car body and a toolbox, etc., and has the following characteristics...

AI Technical Summary

Problems solved by technology

[0005] It can be seen from the above that the volume of the existing wrecker trailer is large, and it is effective when towing the illegally parked vehicle on the road, but it is difficult to tow the non-motor vehicle lane or the vehicle on the narrower section of the road. Larger, and it takes a long time to dispatch the trailer. In summary, the existing trailer is not suitable for narrow road conditions, so short-distance moving is even more difficult for large trailers
