Description

Technical Field

[0001] The invention relates to the technical field of auxiliary running wheels for snowmobiles, and in particular to a quick-installation structure of auxiliary running wheels for snowmobiles. Background Art

[0002] The current snowmobile auxiliary driving wheels are provided with two auxiliary driving wheel assembly units on both sides of each snowboard, and the ice blades, snowboards and auxiliary wheel mounting bases are fixed together, as shown in the attached figure of the specification. Figure 1 The auxiliary wheel assembly unit is connected to the auxiliary wheel by a single-sided Z-shaped connecting arm. Two assembly units need to be installed on each auxiliary mounting seat of the sled board and fixed by latches, as shown in the attached figure of the manual. Figure 2 .

[0003] Such a structure will bring many inconveniences during use. Due to limited space, it is difficult to position the pin, and the process is cumbersome, resulting in a series of assembly problems. During disassembly, if the pin is deformed by force, quick disassembly and assembly cannot be achieved, and corresponding tools must be used, which takes more time and manpower.

[0004] The prior art has a Z-shaped independent connecting arm structure in terms of performance, as shown in the accompanying drawings of the specification. Figure 3 , which can easily lead to uneven lateral force, severe wear of the auxiliary wheel, vehicle deviation, and severe deformation of one side of the auxiliary wheel mounting seat.

[0005] In summary, the existing structure is time-consuming and laborious to disassemble and assemble, has a complex structure, and is inconvenient to disassemble and assemble. Summary of the invention

[0006] In view of the above-mentioned deficiencies in the prior art, the technical problem to be solved by this patent application is: how to provide a quick-installation structure for auxiliary driving wheels of a snowmobile that can achieve rapid positioning and installation, save time and effort, is easy to implement, has high efficiency and high reliability.

[0007] In order to achieve the above object, the present invention adopts the following technical solutions:

[0008] The auxiliary wheel mounting structure of the present invention is a structure in which the auxiliary wheel mounting seat and the auxiliary wheel mounting unit are installed. The auxiliary wheel mounting seat comprises a bottom plate, two side plates and a positioning pin. The two side plates are welded on both sides of the bottom plate, and pin holes are arranged opposite to each other on the two side plates, and the positioning pins are fixedly installed in the pin holes. Auxiliary wheel positioning rails are arranged opposite to each other on the two side plates, and the auxiliary wheel positioning rails are bent, and the height of the inner side of the auxiliary wheel positioning rails is higher than the height of the outer side opening. The auxiliary wheel mounting wheel assembly unit comprises a π-type auxiliary wheel support welding bracket and an auxiliary wheel driving wheel, and two auxiliary wheel driving wheels are arranged, and the π-type auxiliary wheel support welding bracket comprises a flat steel, a wheel mounting shaft and a connecting plate, and the two ends of the flat steel are fixedly connected to the connecting plate respectively, and the wheel mounting shaft is fixedly installed on the connecting plate outwardly, and the two wheel mounting shafts are coaxially arranged, and the auxiliary wheel driving wheel is mounted on the wheel mounting shaft.

[0009] In this way, the auxiliary wheel mounting seat side plate has a precisely designed auxiliary wheel positioning track inside, which has a simple structure and can use gravity to quickly and accurately position the auxiliary wheels after they land, ensuring that the sled is properly stressed. When the sled handrail is gently lifted, the auxiliary running wheel assembly unit is slid along the internal guide rail of the auxiliary wheel mounting seat to quickly position and install the wheel; when disassembling, the auxiliary running wheel assembly unit can fall off by itself under its own weight, which is simple and convenient without any tools.

[0010] Furthermore, two positioning pins are provided to better achieve connection positioning.

[0011] Furthermore, it also includes a positioning plate, and the two side plates are provided with positioning notches that penetrate through them, and the two sides of the positioning plate are plugged into the positioning notches, and the positioning plate is welded to the bottom plate and the side plates to increase the connection strength.

[0012] Furthermore, two limiting rings are fixedly mounted on the flat steel, and the distance between the inner sides of the limiting rings matches the distance between the outer sides of the two side plates, so that the position of the auxiliary wheel can be better limited, which is convenient for installation and disassembly.

[0013] Furthermore, the two side plates are also provided with buffer notches, and the buffer notches are arranged on the lower outer side of the auxiliary wheel positioning rails, so as to facilitate installation and disassembly.

[0014] Furthermore, the auxiliary wheel mounting seat is made of welded steel plates. It is light in weight, simple in structure, can be cut by laser, has low manufacturing cost, and is easy to mass produce. The installation method is to fix the ice skates, sleds and auxiliary wheel mounting seat together without disassembly.

[0015] In summary, the quick-install structure of the auxiliary driving wheel of the snowmobile has the following beneficial effects: each auxiliary wheel mounting seat only needs to install one auxiliary driving wheel assembly unit to achieve fast and accurate positioning and disassembly and assembly, without the aid of any tools, and is easy to use, simple to make, and easy to implement, which reduces disassembly and assembly time, saves manufacturing costs, and improves work efficiency.
