Description

Technical Field

[0001] The utility model relates to the field of front guiding wheels, and more specifically to an installation mechanism for guiding wheels of a trailer caravan. Background Art

[0002] At present, the guiding wheels of trailer caravans are only used for short-distance towing, so the installation and fixing structure is simple. Although there are various types and different forms of guiding wheels can support functions such as disassembly, flipping, and lifting respectively, after the application of an electric lifting mechanism, it is required that the guiding wheels can not only be towed for short distances, but also have functions of low-speed driving, steering, and lifting. This greatly increases the requirements for the strength and reliability of the guiding wheels and the installation mechanism. It is found in the design that in order to increase the ability of the guiding wheels to drive at low speeds on general roads and ensure sufficient lifting height, it is impossible to meet a relatively high ground clearance, nor can the vehicle have good passability.

[0003] Therefore, while meeting the strength and lifting functions, in order to ensure good ground clearance and passability in the future, a rotatable installation mechanism is added, which is convenient to operate and firmly installed. Summary of the Utility Model

[0004] The main technical problem to be solved by the utility model is to provide an installation mechanism for guiding wheels of a trailer caravan, which can solve the problem that while meeting the strength and lifting functions, it can ensure good ground clearance and passability in the future, and adds a rotatable installation mechanism, which is convenient to operate and firmly installed.

[0005] To solve the above technical problem, according to one aspect of the utility model, more specifically, it is an installation mechanism for guiding wheels of a trailer caravan, including a guiding wheel installation mechanism, and the guiding wheel installation mechanism includes a vehicle frame, a guiding wheel device, Component One, Component Two, Spring One, Component Three, a pin bolt, a plug pin, and Spring Two.

[0006] Furthermore, the component includes a mounting plate, a U-shaped plate, a U-shaped plate with a semi-circular notch, a triangular beam, and a hanging plate.

[0007] Furthermore, Component Two includes a semi-circular steel pipe, and U-shaped plates with semi-circular notches are fixedly connected to the outer side walls of the semi-circular steel pipe.

[0008] The beneficial effects of an installation mechanism for guiding wheels of a trailer caravan of the utility model are as follows:

[0009] The entire installation mechanism first fastens the casing assembly three made of two semicircular nylon with flanges onto the circular tube crossbeam of the vehicle frame. Then, it fastens the assembly two onto the assembly three from the front and back. Before fastening, lubricating grease is added to the nylon tube in the assembly three to ensure smooth rotation. Then, the assembly two is fixedly connected to the lower bracket of the guide wheel through four sets of bolts and nuts, enabling the guide wheel to freely rotate around the assembly three. Next, the assembly one is connected and fixed to the vehicle frame, and then the guide wheel is placed in the semicircular groove of the assembly one. The spring two is sleeved into the pin bolt, and the pin is inserted into the pin bolt hole to prevent the spring two from falling off. Then, the pin bolt passes through the bolt hole of the assembly one and is tightly screwed and fixedly connected to the guide wheel bracket nut. The front end of the pin bolt has a guiding function, and the spring two can make the operator labor-saving and effectively position, thus successfully completing the fixation. By disassembling and assembling the pin bolt, the guide wheel can be separated from or fixedly connected to the assembly one. After separation, the guide wheel can be fixedly connected to the assembly two. The nylon tube forms a rotating shaft between the assembly two and the circular tube crossbeam of the vehicle frame, enabling the guide wheel to rotate around the shaft to achieve a certain angle of flipping of the guide wheel and increase the ground clearance. One end of the spring one is connected to the hanging plate in the assembly one, and the other end is connected to the guide wheel, providing a certain pre-tightening force when the entire guide wheel is fixed and playing a role of pulling up and hanging after the guide wheel flips, preventing the guide wheel from dropping to the ground during driving.
