Description

Technical Field

[0001] The present application belongs to the technical field of vehicle suspension, and specifically relates to a suspension mechanism of a ski resort transport vehicle. Background Art

[0002] The transporter's suspension mechanism is a system connecting the vehicle body and wheels. Its main function is to absorb road bumps, reduce vehicle body vibrations, maintain wheel contact with the ground, ensure that the wheels are always in contact with the ground, ensure vehicle driving stability, support the vehicle's weight, and withstand cargo loads.

[0003] Snowmobile suspensions face unique challenges, especially in cold environments. They must overcome the challenges of icy conditions and the strength and toughness of metal. Accumulated snow can clog suspension components, disrupting proper operation or even causing damage. Metal becomes brittle when exposed to cold, hindering mechanical cushioning. Rubber, on the other hand, exhibits minimal changes in physical properties due to its integrated hardness and temperature variations, but can be detrimental to mechanical connections.

[0004] However, the suspension mechanism of traditional ski resort transport vehicles adopts a single system redundant protection structure. In this special scenario, the durability of the suspension mechanism of the ski resort transport vehicle is reduced. Utility Model Content

[0007] By adopting the above technical solution, the equipment uses the chassis as the main supporting component, adjusts the position of the movable adjustment block by rotating the nut, and the rotation of the side extrusion block corresponds to the limiting bearing, completing the redundancy of the upper mechanical part.

[0016] In a preferred embodiment, the inner surface of the bearing is provided with connecting screws, the outer surface of the bearing is provided with a connecting frame, and the connecting screws pass through the bearing and are fixedly installed on the connecting frame.

[0017] By adopting the above technical solution, the connecting screws are rotated and screwed into the connecting frame, making it convenient to connect the bearing and the connecting frame.

[0018] In a preferred embodiment, an outer tire is fixedly connected to the outer surface of the connection frame, and an outer protective plate is fixedly connected to the inner surface of the corresponding connection frame of the outer tire.

[0020] In a preferred embodiment, a protruding gasket is fixedly connected to the outer surface of the outer tire, and a side rubber gasket is fixedly connected to the outer surface of the outer tire.

[0021] By adopting the above technical solution, the protruding gasket increases the friction when the outer tire contacts the ground, ensuring the stability of the vehicle. The side rubber gasket is attached to the side with an arc, which is different from the protruding gasket.

[0031] Example:

[0032] Reference Figure 1-5 A suspension mechanism of a ski resort transport vehicle includes a chassis 1, an inner surface of the chassis 1 is fixedly connected to a support rod 3, the outer surfaces of both ends of the support rod 3 are fixedly connected to bearings 4, a threaded rod 5 is welded to the inner surface of the upper end of the chassis 1, and a movable adjustment block 6 is movably sleeved on the outer surface of the threaded rod 5. The outer surfaces of the threaded rod 5 on both sides of the movable adjustment block 6 are movably connected to the support rod 3, the outer surface of the movable adjustment block 6 corresponding to the bearing 4 is movably connected to a side extrusion block 7, and the outer surface of the side extrusion block 7 is movably connected to an adjusting screw 8.

[0033] The equipment uses the chassis 1 as the main supporting component, and adjusts the position of the movable adjustment block 6 by rotating the nut 2. The rotation of the side extrusion block 7 corresponds to the limiting bearing 4, completing the redundancy of the upper mechanical part. The rotation of the adjusting screw 8 facilitates the adjustment of the tightness of the side extrusion block 7 and the corresponding fixation. Through the redundancy of the low-voltage system and the mechanical part, if one set fails, the other set can immediately intervene to ensure the stable operation of the vehicle axle.

[0034] Reference Figure 1-5 A stress groove 9 is provided on the inner surface of the chassis 1 , and a rubber gasket 10 is provided on the upper surface of the chassis 1 corresponding to the movable adjustment block 6 .

[0035] The stress groove 9 provides stress toughness for the chassis 1 and ensures the stability of the physical structure. The rubber gasket 10 provides better friction for the movable adjustment block 6, ensuring that the movable adjustment block 6 is fixed stably after adjusting the position, thereby better applying external force to the bearing 4 by the side extrusion block 7.

[0036] Reference Figure 1-5 An extension block 11 is provided on the inner surface of the support rod 3. A lifting rod 12 is movably sleeved on the inner surface of one end of the extension block 11 away from the support rod 3. A lifting ring 13 is fixedly connected to the upper surface of the lifting rod 12.

[0037] The lifting rod 12 is inserted into the extension block 11 and fixed by the knob of the fixing screw 14 , and the lifting ring 13 completes the lifting of the bearing 4 .

[0038] Reference Figure 1-5 A fixing screw 14 is provided on the outer surface of the extension block 11 corresponding to the lifting rod 12, and a bottom baffle 15 is movably connected to the outer surface of the lifting rod 12.

[0039] The knob of the fixing screw 14 fixes the lifting ring 13 and the bottom baffle 15. The bottom baffle 15 is convenient for protecting the lower end to prevent ice and snow from squeezing the suspension.

[0040] Reference Figure 1-5 A side connecting frame 20 is welded to the inner surface of the bearing 4 , and a placement base plate 21 is welded to the lower surface of the side connecting frame 20 .

[0041] The side connection frame 20 and the placement base plate 21 provide a larger force-bearing structure for the suspension, ensuring the stability of the vehicle and providing support for the installation of other components of the vehicle.

[0042] Reference Figure 1-5 The inner surface of the bearing 4 is provided with a connecting screw 16 , and the outer surface of the bearing 4 is provided with a connecting frame 17 . The connecting screw 16 passes through the bearing 4 and is fixedly installed on the connecting frame 17 .

[0043] The connecting screw 16 is rotated and screwed into the connecting frame 17 to facilitate the connection between the bearing 4 and the connecting frame 17.

[0044] Reference Figure 1-5 The outer surface of the connecting frame 17 is fixedly connected to an outer tire 18 , and the outer tire 18 is fixedly connected to the inner surface of the corresponding connecting frame 17 to an outer protective plate 19 .

[0045] The outer tire 18 is a main tire component. When the outer tire 18 is running, the outer protection plate 19 blows the snowflakes to the outside through the airflow.

[0046] Reference Figure 1-5 A protruding gasket 22 is fixedly connected to the outer surface of the outer tire 18, and a side rubber gasket 23 is fixedly connected to the outer surface of the outer tire 18.

[0047] The protruding gasket 22 increases friction when the outer tire 18 contacts the ground, ensuring stable driving of the vehicle. The side rubber gasket 23 is attached to the side with an arc, which is different from the protruding gasket 22.

[0048] The implementation principle of the suspension mechanism embodiment of a ski resort transport vehicle in the present application is as follows:

[0049] The equipment uses the chassis 1 as the main supporting component, and the connecting frame 17, outer tire 18, outer protection plate 19, protruding gasket 22, and side rubber gasket 23 constitute the tire body. The connecting frame 17 facilitates the connection of the suspension mechanism. The brake includes a dual redundant system and meets GB12676-2014 The requirements include low-voltage system redundancy and mechanical part redundancy. If one set fails, the other set can be immediately intervened. The low-voltage system redundancy includes support rod 3 and bearing 4, which are hard-connected with rubber shock-absorbing pads. The suspension also has independent mechanical brakes. The lifting rod 12 is stuck in the extension block 11 and fixed by the knob of the fixing screw 14. The lifting ring 13 completes the support of the bearing 4. The position of the movable adjustment block 6 is adjusted by rotating the nut 2. The rotation of the side extrusion block 7 corresponds to the restriction of the bearing 4 to complete the mechanical part redundancy. The stress groove 9 provides stress toughness for the chassis 1 to ensure the stability of the physical structure. The role of the rubber gasket 10 is to provide better friction for the movable adjustment block 6 to ensure the stability of the movable adjustment block 6 after adjusting the position, thereby better applying external force to the bearing 4 by the side extrusion block 7. The knob of the fixing screw 14 fixes the lifting ring 13 and the bottom baffle 15. The bottom baffle 15 is convenient for protecting the lower end to prevent ice and snow from squeezing the suspension. The rotation of the connecting screw 16 is screwed into the connecting frame 17 to facilitate the connection of the bearing 4 and the connecting frame 17.
