[0002] Snowmobiles are vehicles used to travel on snow. They move by rotating tracks and do not require specific roads. Snowmobiles usually have only one or two passengers and are often used for surveillance and rescue purposes at ski resorts. They are also widely used by amateur players for winter outdoor sports.

[0003] A sled is provided on the front side of the snowmobile, and tracks are provided on the rear side. The snowmobile is driven forward by the rotation of the tracks, and steering is achieved by controlling the inclination angle of the sled.

[0004] There are two types of steering mechanisms for existing snowmobiles: one is that the steering column is directly connected to the snowboards on both sides through a tie rod, and the other is electronic power steering. The steering column is directly connected to the snowboard through a tie rod, which requires a lot of force for steering, making it difficult for the driver to drive and inconvenient to operate; and because the road conditions of snowmobiles are very bad, the electronic power steering is prone to damage, resulting in a high failure rate of the steering mechanism.

The steering column 2 drives the primary transmission mechanism to move, and then drives the secondary transmission mechanism to move, and then the steering of the sled is realized through the secondary transmission mechanism. The transmission is realized through the two-stage transmission mechanism, and then the power-assisting effect is realized through mechanical transmission, so that the driver's steering operation requires less force and the driver's steering operation is more convenient.

[0019] The present invention is further described below in conjunction with specific embodiments. However, people familiar with the art should understand that the detailed description given here in conjunction with the drawings is for better explanation, and the structure of the present invention necessarily exceeds these limited embodiments. For some equivalent replacement schemes or common means, they are no longer described in detail herein, but still belong to the scope of protection of the present application.

[0020] For details, please refer to the attached Figure 1-Figure 3 An operating column 1 is installed on the top of the steering column 2, a sleeve is provided on the operating column 1, a fixing frame is fixedly installed on the snowmobile body 13, and the fixing frame and the sleeve are detachably connected, thereby realizing the installation of the operating column 1.

[0021] The fixing frame includes a rear support frame 14 and a front support rod 15. The rear support frame 14 is arranged at the rear side of the steering column 2, and the front support rod 15 is arranged at the front side of the steering column 2. In this embodiment, the front side refers to the direction of travel of the snow vehicle body 13, and the rear side refers to the rear side of the direction of travel of the snow vehicle body 13.

[0022] In this embodiment, there are two rear support frames 14 symmetrically arranged on both sides of the snow vehicle body 13. The rear support frames 14 are inclined from bottom to top and gradually approach the steering column 2. The bottom of the rear support frame 14 is fixedly connected to the snow vehicle body 13, and the top of the rear support frame 14 is detachably connected to the sleeve of the operating column 1.

[0023] There are two front support rods 15 symmetrically arranged on both sides of the snow vehicle body 13. The front support rods 15 are inclined from bottom to top and gradually approach the steering column 2. The bottom of the front support rod 15 is fixedly connected to the snow vehicle body 13, and the top of the front support rod 15 is detachably connected to the sleeve of the operating column 1, thereby realizing the installation of the steering column 2 and the operating column 1.

[0024] The mounting frame includes an upper fixing rod 5 and a lower fixing rod 6. The upper fixing rod 5 is arranged parallel to and spaced apart from the upper side of the lower fixing rod 6. Both ends of the upper fixing rod 5 and the lower fixing rod 6 are provided with mounting parts. Both ends of the upper fixing rod 5 and the lower fixing rod 6 are detachably connected to the snowmobile body 13.

[0025] In this embodiment, the upper fixing rod 5 and the lower fixing rod 6 are both angle steels with high anti-deformation strength, thereby ensuring more stable steering.

[0026] The primary transmission mechanism is a lever mechanism, and the secondary transmission mechanism is a four-bar linkage mechanism.

[0027] The primary transmission mechanism includes a swing rod 3, a rotating shaft 4 and a lever 9. A mounting sleeve 12 is fixedly mounted on one end of the upper fixed rod 5. The middle part of the rotating shaft 4 is rotatably mounted on the mounting sleeve 12. The swing rod 3 and the lever 9 are both arranged on the upper side of the upper fixed rod 5. The swing rod 3 and the lever 9 are respectively arranged on opposite sides of the rotating shaft 4 and are both arranged along the radial direction of the rotating shaft 4. One end of the swing rod 3 and one end of the lever 9 are both fixedly connected to the rotating shaft 4, and the other end of the swing rod 3 is fixedly connected to the lower end of the steering column 2. The rotation of the steering column 2 can drive the swing rod 3 to move, and then drive the lever 9 to move.

[0028] In this embodiment, the length of the lever 9 is smaller than that of the swing lever 3, so that the power arm is larger than the resistance arm, thus achieving a labor-saving effect.

[0029] The secondary transmission mechanism includes a first steering swing arm 7, a second steering swing arm 8 and a steering plate 11. The first steering swing arm 7 and the second steering swing arm 8 are arranged in parallel and at intervals, and one end of the first steering swing arm 7 and one end of the second steering swing arm 8 are both extended between the upper fixed rod 5 and the lower fixed rod 6, and are rotatably connected to the upper fixed rod 5 and the lower fixed rod 6. The steering plate 11 is arranged on the lower side of the first steering swing arm 7 and the second steering swing arm 8. The steering plate 11 is located between the first steering swing arm 7 and the second steering swing arm 8, and both ends of the steering plate 11 are rotatably connected to the middle part of the first steering swing arm 7 and the middle part of the second steering swing arm 8 respectively.

[0030] Connecting holes are provided at both ends of the steering plate 11, and connecting parts are formed at both ends of the steering plate 11. Both ends of the steering plate 11 are rotatably connected to the steering knuckles on the corresponding sides through pull rods, and the steering knuckles are rotatably mounted on the snowmobile body 13. Each sled is mounted on the steering knuckles on the corresponding sides and rotates synchronously therewith, thereby realizing synchronous steering of the sleds on both sides.

[0031] The power steering structure of the snowmobile also includes a connecting rod 10, which is located between the lever 9 and the first steering swing arm 7, one end of the connecting rod 10 is hinged to the other end of the lever 9, and the other end of the connecting rod 10 is rotatably connected to the other end of the first steering swing arm 7.

[0032] Since the power arm driving the first steering swing arm 7 to move is larger than the resistance arm driven by the first steering swing arm 7 to drive the steering plate 11 to move, the labor-saving effect can also be achieved.

[0033] When turning, the operating column 1 rotates, and the operating column 1 drives the steering column 2 to rotate, which in turn drives the swing arm 3 to rotate around the rotating shaft 4, and then drives the lever 9 to move through the rotating shaft 4. The lever 9 drives the first steering swing arm 7 to move through the connecting rod 10, and then drives the steering plate 11 to move. Due to the existence of the second steering swing arm 8, it can ensure that the steering plate 11 maintains its original posture during the movement, thereby ensuring that the rotation angles of the sleds on both sides of the steering plate 11 are consistent.

[0034] The above is only a preferred embodiment of the present invention, and does not limit the present invention in other forms. Any technician familiar with the profession may use the above disclosed technical content to change or modify it into an equivalent embodiment with equivalent changes. However, any simple modification, equivalent change and modification made to the above embodiment according to the technical essence of the present invention without departing from the technical solution of the present invention still belongs to the protection scope of the technical solution of the present invention.
