Description

Technical Field

[0001] This utility model relates to the field of snowmobile accessories technology, and in particular to a snowmobile ski shock absorption structure. Background Technology

[0002] The snowmobile's skis and suspension system are central to its handling and comfort. Despite continuous technological advancements, this shock-absorbing structure still faces some challenges during use. In actual use, snowmobiles often need to jump over snow slopes. Upon landing, the suspension needs to absorb huge vertical impact energy to prevent bottoming out and maintain vehicle stability. Snow melts during operation and seeps into parts such as joint bearings and connecting rod bushings. When the temperature drops again, this moisture freezes, causing parts to seize or wear abnormally. Shock absorber rods are also prone to surface icing, resulting in huge friction between the seals and the shock absorber rods during subsequent shock absorption, hindering the smooth movement of the shock absorber. In addition, rubber seals will harden under low temperatures, which not only affects the overall operation but also shortens the service life of the shock absorption mechanism. Utility Model Content

[0003] This invention addresses the problem of low temperatures affecting shock absorption mechanisms by providing a shock absorption structure for snowmobile skis.

[0004] The technical solution adopted by this utility model to solve the above-mentioned technical problems is: a snowmobile ski shock absorption structure, including skis; The top of the sled is equipped with a connecting frame, which is connected to a shock absorber frame consisting of a set of shock absorber rods. A cleaning frame is installed on the shock absorber frame, and the position of the cleaning frame corresponds to the position of the movable end of the shock absorber. The cleaning frame features a set of docking plates at its bottom. Inside these plates is a temperature control plate to maintain temperature and several ice-crushing shafts to remove ice from the shock absorber rods. This reduces excessive friction between the shock absorber rods, controlling the snowmobile's shock absorption performance. The ice-crushing shafts at the bottom of the cleaning frame, along with the movable end blocks, effectively remove ice from the shock absorber rods, preventing increased friction and ensuring stable shock absorption performance. The built-in temperature control plate maintains a constant temperature at the connection points, preventing lubricant stagnation and hardening of the seals. The upturned design of the skid front end, combined with the front lifting shaft, improves snowmobile passability and prevents jamming. Combined with a sponge pad for cleaning and insulation, it reduces wear from dirt and ice debris, extends the lifespan of the shock absorber components, and comprehensively improves the snowmobile's operational stability and durability in low-temperature environments.

[0005] A further preferred embodiment of this utility model is as follows: both sides of the connecting frame are provided with docking holes, and connecting end blocks are connected inside the docking holes.

[0021] This embodiment mainly describes the title of a snowmobile ski shock absorption structure. Please refer to [link / reference]. Figures 1-6 Specifically, a snowmobile ski shock absorption structure includes a ski board 1. A connecting frame 11 is provided on the top of the sled 1.

[0024] A further preferred embodiment of this utility model is: Figure 4 As shown, the top of the cleaning frame 3 is provided with a set of symmetrically arranged snap-fit ​​shafts 31. The two ends of the snap-fit ​​shafts 31 are arc-shaped and have semi-circular frames inside. The semi-circular frames are snapped onto the outside of the shock absorber frame 2 and are snapped together with the snap-fit ​​shafts 31. With the help of the semi-circular frames, the cleaning frame 3 can be snapped onto the outside of the shock absorber frame 2.

[0025] A further preferred embodiment of this utility model is: Figure 5 The docking plate 32 shown has an extension plate on its outside, and the extension plate has an inclined sliding groove. The bottom of the docking plate 32 has a set of resettable sliding frames 33. The movable ends of the sliding frames 33 are connected to docking shafts 331. The docking shafts 331 can abut against the outer wall of the shock absorber rod. The docking shafts 331 can be movably locked inside the sliding groove. The docking shafts 331 can abut against the outer wall of the shock absorber rod, thereby controlling the distance between the upper limit plate 34 and the lower limit plate 35. The bottom ice crushing shaft 36 can be abut against the shock absorber rod to reduce the formation of ice layer from the water film and reduce the impact on the buffer. The docking shaft 331 has a fixing groove inside, and a set of straight rods are connected inside the fixing groove. The two ends of the straight rods are respectively connected to the upper limit plate 34 and the lower limit plate 35. The upper limit plate 34 and the lower limit plate 35 are both provided with arc-shaped grooves inside and move with the docking shaft 331. The lower limit plate 35 has several fixing holes on one side edge of the arc shape. The ice crushing shaft 36 is locked inside the fixing holes. The ice crushing shaft can play the role of clearing the ice layer, ensuring that the motorcycle is in a stable state during riding, and reducing the impact of ice on the moving end of the shock absorber and the bottom rubber layer, which affects the shock absorption effect.

[0026] A further preferred embodiment of this utility model is: Figure 5 and Figure 6 The ice-crushing shaft 36 shown has a rectangular groove inside, and a reset shaft 37 with an inclined arrangement is connected to the bottom of the rectangular groove. A metal block and a pressure ball 38 are connected to the top of the reset shaft 37. Both the pressure ball 38 and the metal block are hemispherical. A hollow tube is connected to the bottom of the ice-crushing shaft 36, and a fixed stop 39 is set at the bottom of the hollow tube. The fixed stop 39 is arc-shaped and evenly arrayed on the outside of the movable end of the shock absorber. During the buffering process of the shock absorber, the outer wall of the shock absorber can abut against the surface of the reset shaft 37, and the metal ball can abut against the outer wall of the movable end of the shock absorber, reducing the amount of sticky dirt or ice carried on the surface and reducing the impact on components such as the sealing ring. When the reset shaft 37 is squeezed, the pressure ball 38 can abut against the outer wall of the ice-crushing shaft 36, and the internal air pressure changes, which can make the movable end block 391 at the bottom move.

[0027] A further preferred embodiment of this utility model is: Figure 6 As shown, the fixed stop 39 has a piston groove inside, and a movable end block 391 is provided inside the piston groove. One end of the movable end block 391 is triangular. The ice crushing shaft 36 has an air supply channel inside. The deformation of the air pressure ball 38 can control the air pressure inside the piston groove. The movable end block 391 can press against the outer wall of the movable end of the shock absorber under the action of air pressure change for ice crushing. When the air pressure inside the air pressure ball 38 at the top changes, it can cause the movable end block 391 inside the piston groove to move outward, which can set the triangular protrusion on the On the outer wall of the movable end of the shock absorber, ice can be squeezed and fall off during operation. The top reset shaft 37 can squeeze the remaining ice protrusions during the movement of the movable end of the shock absorber, crushing and dropping them. At the same time, the pressure on the rear air pressure ball 38 is changed, thereby changing the internal air pressure. The triangular protrusion also moves outward, squeezing the remaining ice at the bottom and causing cracks to appear on the surface of the ice. This makes it easier for the ice formed by the water film to fall off during operation, reducing the impact on the shock absorber 2 and affecting the stability of operation.

[0028] A further preferred embodiment of this utility model is: Figure 5 As shown, a sponge pad is provided on the inner wall of the arc-shaped side of the upper limit plate 34 for cleaning the outer wall of the shock absorber rod. Together with the temperature control plate 321, it can clean and wipe the surface of the shock absorber rod, reducing dirt residue. The sponge pad is close to the temperature control plate 321, which can reduce the impact of low external temperature, reduce the occurrence of freezing due to high water content, and avoid friction between the sponge pad and the outer wall of the moving end of the shock absorber rod.

[0029] A further preferred embodiment of this utility model is: Figure 5As shown, the mating plate 32 has a snap-fit ​​groove inside, and the temperature control plate 321 is set inside the snap-fit ​​groove. The temperature control plate 321 has several heating plates inside, which are used to control the temperature of the connection of the movable end of the shock absorber rod, reduce the stagnation of the lubricant in low temperature environment. During the operation of the equipment, the heating of the temperature control plate can keep the movable connection of the shock absorber rod in a constant temperature state, reduce the hardening of the sealing ring, etc., and also ensure that the lubricant will not stagnate in low temperature environment. Together with the ice crushing shaft 36 at the bottom, it can ensure the stable operation of the shock absorber 2 in low temperature state.
