Description

Technical Field

[0001] The utility model relates to the technical field of trailer mudguards, and particularly relates to a splash-proof system device for a towing trailer. Background Art

[0002] In the current trailer transportation system, when connecting an A-trailer tractor to a B-trailer, a common technical problem is that the gooseneck part of the B-trailer is prone to scraping against the mudguard installed above the rear axle of the A-trailer during the docking process. This scraping phenomenon not only causes surface damage to the mudguard but may also lead to more serious collision injuries, further affecting the overall structural safety of the trailer.

[0003] Particularly crucial is that the splash-proof device equipped on the trailer is mainly used to prevent debris such as gravel and mud splashed by the tires during the trailer's driving from damaging the surrounding environment and the vehicle itself. Once damaged during the scraping with the B-trailer gooseneck, it will directly affect the normal functioning of its protection function, thus increasing the safety hazards during driving.

[0004] Therefore, to solve the inevitable scraping problem between the B-trailer gooseneck and the A-trailer mudguard during the connection operation, a splash-proof system device for a towing trailer is now needed. Summary of the Utility Model

[0005] The utility model aims to provide a splash-proof system device for a towing trailer. Under the condition of meeting the relevant production standards of the trailer, the splash-proof system device is designed and manufactured in two parts, namely the front section of the mudguard is arranged at the front of the rear axle of the A-trailer, and the rear axle mudguard is arranged at the rear end of the rear axle of the A-trailer. While meeting the splash-proof requirements, the scraping problem is solved to ensure the integrity and effectiveness of the splash-proof device.

[0006] To achieve the above object, the utility model adopts the following technical solutions:

[0007] Based on the structure of the existing double-trailer articulated train, the utility model disassembles the splash-proof device into two parts for design and installation.

[0014] Further, the thickness of the front fender section is 45 mm - 55 mm. According to the requirements of Article 6.1.2.3 of GB34659-2017, the extension distance between the highest point and the lowest point on the cross-section of the fender shall not be less than 45 mm. Therefore, the thickness is set to 45 mm - 55 mm to meet the relevant requirements and at the same time effectively prevent mud and water splashed during the rotation of the tires from flying horizontally and affecting pedestrians.

[0015] Further, the access ladder assembly includes an installation platform, which is arranged at the rear end of the front fender section, and a telescopic ladder is provided at the lower part of the installation platform.

[0016] Furthermore, the distance between the bottom of the rain curtain and the ground is not greater than 200 mm, ensuring that the rain curtain can block the gravel and mud splashed by the tires, while not affecting the normal driving of the vehicle and ensuring driving safety.

[0017] Furthermore, the horizontal plane where the installation platform is located is lower than the horizontal plane where the front section of the fender is located. The installation platform is slightly lower than the fender, enabling the installation platform to also function as part of the fender for protection, and at the same time facilitating the operator to get on and off the vehicle.

[0018] Furthermore, a slide rail groove is provided at the lower part of the installation platform, and one end of the telescopic ladder is provided with a sliding wheel, which drives the telescopic ladder to slide in the slide rail groove. This allows the telescopic ladder to be telescopically retracted in the slide rail groove, opened when in use, making it more convenient for operation and storage, reducing the occupied space, and also being more conducive to operation.
