Description

Technical Field

[0001] This utility model relates to the field of semi-trailer parts, specifically a prefabricated mudguard for semi-trailers. Background Technology

[0002] Mudguards are plate-like structures installed behind the outer frame of the wheels, typically made of high-quality rubber, though some are made of engineering plastics. As an important component of semi-trailers, mudguards play a crucial role in protecting the vehicle and pedestrians by preventing mud, water, stones, and other debris from splashing out. Simultaneously, mudguards prevent mud and water from entering the wheels, thereby improving vehicle stability and the safety of passengers.

[0003] For example, the utility model disclosed in publication (announcement) number CN202413943U is a prefabricated mudguard structure, including a vehicle frame, upper and lower fixing frames are fixedly installed on both sides of the rear of the vehicle frame, an upper mudguard is fixedly installed between the upper and lower fixing frames, and a lower mudguard is fixedly connected to the bottom of the upper mudguard by a pressure strip.

[0004] The aforementioned utility model has a relatively simple structure, insufficient safety protection, and cannot be completely disassembled. Currently, most mudguards used on semi-trailers combine the upper mudguard with the front and rear mudguards into an integrated structure such as a mudguard cover. Using this type of mudguard is not conducive to its disassembly and maintenance. Furthermore, when part of the integrated mudguard is damaged and needs to be replaced, the entire mudguard structure needs to be replaced, resulting in a certain waste of manpower and material resources. At the same time, semi-trailers are relatively large, which means that the integrated mudguard structure adapted to the semi-trailer occupies a lot of space, making it inconvenient for mass production and transportation. Utility Model Content

[0005] The purpose of this utility model is to provide a prefabricated mudguard for semi-trailers to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a prefabricated mudguard for a semi-trailer, comprising a connecting frame, a central baffle is provided at the center of one side of the connecting frame, and side baffles are symmetrically provided on both sides of the central baffle. The central baffle is fixedly connected to one end of the connecting frame by a plurality of first connecting ears and fixing bolts, and each side baffle is fixedly connected to the connecting frame by a plurality of second connecting ears and fixing bolts. Both sides of the connecting frame are fixedly connected to one end of the vehicle frame by a plurality of fixing bolts.

[0007] Preferably, each of the side baffles has an arc-shaped structure.

[0008] Preferably, the connecting frame has through holes on both sides that are compatible with the fixing bolts.

[0009] Preferably, the two side baffles are respectively fixedly connected to positioning blocks on one side close to each other.

[0010] Preferably, the middle baffle has slots on both sides that are adapted to the positioning blocks.

[0011] Preferably, each of the first connecting ears and the second connecting ears has a mounting hole adapted to the fixing bolt.

[0012] Compared with the prior art, the advantages of this utility model are as follows:

[0013] This utility model avoids the increased production process caused by an integrated design by setting a middle baffle and two arc-shaped side baffles on both sides, and at the same time facilitates installation and disassembly. Each side baffle is inserted into the slot of the middle baffle through a positioning block, and the middle baffle and the side baffles are fixedly connected to the connecting frame through a first connecting ear and a second connecting ear and a matching fixing bolt. The connecting frame is fixed to the vehicle frame on both sides by fixing bolts. The overall structure is simple and easy to install and disassemble. The arc shape of the side baffles can better fit the outside of the wheel. By splitting the mudguard into a middle baffle and two side baffles, it is easier to produce and transport, and is suitable for mass production. Attached Figure Description
