Description

Technical Field

[0001] The invention belongs to the technical field of sled equipment, and in particular relates to a sled crawler guide wheel frame. Background Art

[0002] A sled is a vehicle designed to travel on snow or ice, usually by sliding or rolling on skis or snow-covered ground. Sleds usually do not use traditional tires, but instead use a design similar to sleds or tracks to improve their ability to travel on soft snow, deep snow or ice. However, the sled track guide wheel frame is an important component of the sled track system, used to support and guide the operation of the track. Its function is to ensure that the track can travel smoothly on snow or other rugged ground while maintaining the tension and stability of the track.

[0003] The existing track guide wheel frame structure design of the sled vehicle is usually relatively simple. The track is directly installed on the outside of the guide wheel frame, and multiple guide wheels are used to help the track maintain the correct running direction. At the same time, the guide wheels can reduce the deviation of the track and ensure the stable operation of the track. However, the functionality is poor. The existing tracks are usually trapezoidal and can be driven on different terrains. However, when driving on a ground with a good environment, the contact friction is large, resulting in high fuel consumption of the vehicle body, which increases the cost of using the sled vehicle. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the disadvantages of the above-mentioned prior art and provide a track guide wheel frame for a sled vehicle.

[0005] The technical solution adopted to solve the above technical problems is: a snowmobile track guide wheel frame, comprising a guide wheel frame assembly, a track body is arranged on the outer side of the guide wheel frame assembly, and an adjustment mechanism is installed at the center of the guide wheel frame assembly; A secondary guide wheel mechanism is installed on the outer side of the guide wheel frame assembly, a main guide wheel mechanism is installed on the outer top of the guide wheel frame assembly, and a driving mechanism is installed at the rear end center of the guide wheel frame assembly; A shock absorber is arranged at the top of the driving mechanism, and the top of the shock absorber is fixedly connected to the sled body.

[0006] Furthermore, the guide wheel frame assembly includes a guide wheel frame body, a front end of the guide wheel frame body is fixedly connected to a plurality of annularly distributed slide rails, a connecting plate is fixedly connected between the front ends of the plurality of slide rails, a front end of the connecting plate is fixedly connected to a plurality of annularly distributed fixing frames, and a connecting shaft is fixedly connected between the plurality of fixing frames and the guide wheel frame body.

[0007] Through the above technical solution, the guide wheel frame body not only facilitates the connection of multiple auxiliary wheels, but is also used for the connection of the driving mechanism. Multiple slide rails are used for the limited sliding of the telescopic strips, thereby facilitating the adjustment of multiple auxiliary wheels, and multiple connecting shafts are used for the rotation of multiple rotating frames.

[0008] Furthermore, the front and rear ends of the inner wall of the crawler body are fixedly connected with limit ring strips, and the center of the inner wall of the crawler body is fixedly connected with two groups of internal teeth.

[0009] Through the above technical solution, the two limiting rings are close to the outer sides of the corresponding secondary wheels, which prevents the track body from shifting when rotating, thereby improving the driving stability of the sled vehicle.

[0010] Furthermore, the adjustment mechanism includes a first motor fixedly installed at the front end center of the connecting plate, the outer wall of the output shaft of the first motor is fixedly connected to a rotating disk, a plurality of arc grooves are opened on the rotating disk, and movable pins are slidably connected in the plurality of arc grooves, and the rear ends of the plurality of movable pins are fixedly connected to telescopic strips, and the plurality of telescopic strips are slidably connected to the corresponding slide rails.

[0011] Through the above technical solution, when the circular track body needs to be adjusted to a triangle, the first motor is started, and the rotating disk is driven to rotate by rotating the output shaft, thereby driving the multiple arc grooves to rotate, thereby driving the multiple movable pins to slide in the corresponding arc grooves. As the multiple telescopic bars slide with the corresponding slide rails, the multiple telescopic bars extend outward, thereby driving the secondary guide wheel mechanism and the main guide wheel mechanism to deform. When the rotating disk rotates a certain angle, the track body changes from a circle to a triangle, thereby increasing the contact friction between the track body and the ground. At the same time, the driving mechanism stops running, and the track body is driven to run through the main guide wheel mechanism. It can travel on relatively harsh ground and has strong functionality.

[0012] Furthermore, the auxiliary guide wheel mechanism includes two rotating frames rotatably connected to the outer walls of multiple connecting shafts, both ends of each of the two rotating frames are rotatably connected to a movable frame, the outer ends of the multiple telescopic strips are fixedly connected to the telescopic frames, and the front and rear ends of the multiple rotating frames, the multiple movable frames and the multiple telescopic frames are all equipped with auxiliary wheels.

[0013] Through the above technical scheme, before adjustment, the track body is driven by the driving mechanism, and at this time, the track body is in a non-rotating state. Since the track body is sleeved on the outer sides of the multiple secondary wheels, when the guide wheel frame body rotates, the guide wheel frame body drives the multiple fixed frames and the corresponding connecting shafts to rotate, thereby driving the multiple rotating frames, the movable frames and the telescopic frames to rotate, and then driving the multiple secondary wheels to revolve. At this time, the multiple telescopic strips are stationary, providing corresponding supporting force, so that the track body revolves, thereby realizing the driving of the sled vehicle. When the track body needs to be adjusted, the multiple telescopic strips extend outward, driving the connected telescopic frames to extend outward, and at the same time, the multiple movable frames rotate, thereby driving the positions of the connected secondary wheels to shift. When the multiple telescopic strips extend out to the specified positions, the track body is adjusted from a circle to a triangle, thereby increasing the contact area with the ground, and being more stable when driving on harsh ground.

[0014] Furthermore, the plurality of movable frames are rotatably connected to corresponding telescopic frames, and the outer sides of the plurality of auxiliary wheels are in contact with the inner wall of the crawler body.

[0015] Through the above technical solution, when the track body is circular or triangular, the track body is tightly wrapped around the outer sides of multiple secondary wheels; when the track body is circular, the track body is not driven; and when the track body is triangular, the track body is driven by the main driving wheel mechanism.

[0016] Furthermore, the main driving wheel mechanism includes two main shafts rotatably connected to one end of one of the telescopic frames, the outer ends of the two main shafts are fixedly connected to main wheels, the outer walls of the two main shafts near the corresponding main wheel positions are fixedly connected to driving gears, the inner ends of the two main shafts are fixedly connected to first bevel gears, a second motor is installed at the center of one of the telescopic frames, and the outer wall of the output shaft of the second motor is fixedly connected to second bevel gears.

[0017] Through the above technical solution, when the crawler body is adjusted to a triangle, the second motor is started, and the second motor drives the second bevel gear to rotate through the output shaft, so that the second bevel gear drives the two first bevel gears to rotate, and the two first bevel gears respectively drive the corresponding main shafts to rotate, thereby driving the connected main wheels and driving gears to rotate, thereby driving the two internal teeth to rotate, realizing the rotation of the crawler body (at this time, the multiple secondary wheels do not revolve), so that the sled vehicle can travel on harsh ground.

[0018] Furthermore, the second bevel gear meshes with the two first bevel gears, and in the assembled state, the two driving gears mesh with the corresponding internal gears.

[0019] Through the above technical solution, when the adjusting mechanism is adjusted, the circular track body is changed into a triangle. At this time, the two sets of internal teeth are respectively meshed with the corresponding driving gears, so that when the driving gear rotates, the meshing internal teeth are driven to rotate, thereby driving the track body to rotate, thereby realizing the driving of the entire sled vehicle.

[0020] The transmission gear of the present invention is a gear shifting device, and a gear shifting device is installed on the transmission gear of the present invention to move the transmission gear of the present invention to the transmission gear of the present invention.

[0021] Through the above technical solution, when the track body is circular, the third motor is started, and the output shaft rotates to drive the drive shaft to rotate, thereby driving the elastic coupling and the first rotating shaft to rotate, so that the first rotating shaft drives the connected movable gear to rotate, thereby driving the multiple connected movable gears to rotate with each other, and the outermost movable gear rotates to drive the ring gear to rotate, so that the ring gear drives the guide wheel frame body to rotate, thereby driving the track body to rotate (at this time, multiple secondary wheels revolve), so that the sled can travel on a ground with a good environment. At this time, the contact area between the track body and the ground is small, resulting in relatively low friction, thereby greatly reducing the fuel consumption of the sled, thereby reducing the cost of use.

[0022] Furthermore, the bottom end of the shock absorber is fixedly connected to the connecting seat, the third motor is installed on the sled body, the multiple movable gears are meshed, the first connecting frame and the second connecting frame are both rotatably connected to the first rotating shaft, the first connecting frame is rotatably connected to the second connecting frame, the first connecting frame is rotatably connected to the third connecting frame, the second connecting frame is rotatably connected to the fourth connecting frame, and the two fourth rotating shafts are rotatably connected to the front end of the fixed shell.

[0023] Through the above technical solution, when the track body is circular and the track body travels on a concave or uneven ground, the track body is buffered by the fixed shell under the action of the shock absorber, and at the same time the first connecting frame, the second connecting frame, the third connecting frame and the fourth connecting frame rotate with each other, and the multiple movable gears inside them rotate in mesh with each other, which facilitates the buffering movement of the entire guide wheel frame, eliminates traditional components such as differentials and gear boxes, reduces the complexity of vehicle manufacturing, and thus reduces the failure rate and maintenance costs. In addition, each track body is operated separately by the third motor, and the power distribution is more flexible, which greatly improves the driving stability of the sled vehicle.

[0024] The beneficial effects of the present invention are as follows: (1) The present invention can adjust the circular track to a triangle by designing the track body and the adjustment mechanism, thereby increasing the contact area between the track and the ground, and can travel more stably on bad ground. When traveling on a good ground, the triangular track can be adjusted back to a circle, so that the contact area between the track and the ground is smaller, resulting in relatively low friction, reducing the fuel consumption of the sled, and thus reducing the cost of use; (2) The present invention designs the secondary guide wheel mechanism, the main driving wheel mechanism and the driving mechanism. When the track is circular, the driving mechanism drives and the main driving wheel mechanism stops, so that the multiple secondary wheels drive the track to rotate during the revolution, and travel on a good ground, reducing fuel consumption. When the track is triangular, the main driving wheel mechanism drives and the driving mechanism stops, and travels on a bad ground, with strong functionality. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0027] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0028] like Figure 1-Figure 7 As shown, a snowmobile track guide wheel frame of the present embodiment includes a guide wheel frame assembly 1, the guide wheel frame assembly 1 includes a guide wheel frame body 101, the front end of the guide wheel frame body 101 is fixedly connected with a plurality of annularly distributed slide rails 102, the front ends of the plurality of slide rails 102 are fixedly connected with a connecting plate 103, the front end of the connecting plate 103 is fixedly connected with a plurality of annularly distributed fixing frames 104, and a connecting shaft 105 is fixedly connected between the plurality of fixing frames 104 and the guide wheel frame body 101. The guide wheel frame body 101 is not only convenient for connecting a plurality of auxiliary wheels 404, but also for connecting a driving mechanism 6. The plurality of slide rails 102 are fixedly connected between the front ends of the plurality of slide rails 102, and the plurality of fixing frames 104 are fixedly connected with the guide wheel frame body 101. 02 is used for the limited sliding of the telescopic strip 305, so as to facilitate the adjustment of multiple secondary wheels 404. Multiple connecting shafts 105 are used for the rotation of multiple rotating frames 401. A track body 2 is provided on the outside of the guide wheel frame assembly 1. The front and rear ends of the inner wall of the track body 2 are fixedly connected with limited ring strips 21. Two groups of internal teeth 22 are fixedly connected to the center of the inner wall of the track body 2. The two limited ring strips 21 are close to the corresponding outer sides of the secondary wheels 404 to prevent the track body 2 from shifting during rotation and improve the driving stability of the sled. A shock absorber 7 is provided at the top of the driving mechanism 6, and the top of the shock absorber 7 is fixedly connected to the sled body.

[0029] like Figure 1-Figure 11 As shown, an adjustment mechanism 3 is installed at the center of the guide wheel frame assembly 1, and the adjustment mechanism 3 includes a first motor 301 fixedly installed at the front center of the connecting plate 103, and the outer wall of the output shaft of the first motor 301 is fixedly connected to a rotating disk 302, and a plurality of arc grooves 303 are provided on the rotating disk 302, and movable pins 304 are slidably connected in the plurality of arc grooves 303, and the rear ends of the plurality of movable pins 304 are fixedly connected to telescopic bars 305, and the plurality of telescopic bars 305 are slidably connected to the corresponding slide rails 102. When the circular crawler body 2 needs to be adjusted to a triangle, the first motor 301 is started, and the output shaft is rotated to drive The rotating disk 302 rotates, thereby driving the multiple arc grooves 303 to rotate, thereby driving the multiple movable pins 304 to slide in the corresponding arc grooves 303. Since the multiple telescopic bars 305 slide with the corresponding slide rails 102, the multiple telescopic bars 305 extend outward, thereby driving the secondary guide wheel mechanism 4 and the main guide wheel mechanism 5 to deform. When the rotating disk 302 rotates a certain angle, the track body 2 changes from a circle to a triangle, thereby increasing the contact friction between the track body 2 and the ground. At the same time, the driving mechanism 6 stops running, and it is driven by the main guide wheel mechanism 5 to travel on relatively harsh ground, with strong functionality.

[0030] like Figure 1-Figure 7As shown, a secondary guide wheel mechanism 4 is installed on the outer side of the guide wheel frame assembly 1, and the secondary guide wheel mechanism 4 includes two rotating frames 401 rotatably connected to the outer walls of multiple connecting shafts 105, and both ends of each of the two rotating frames 401 are rotatably connected to a movable frame 402, and the outer ends of multiple telescopic bars 305 are fixedly connected to a telescopic frame 403, and the front and rear ends of the multiple rotating frames 401, the multiple movable frames 402 and the multiple telescopic frames 403 are all installed with secondary wheels 404. Before adjustment, they are driven to operate by the driving mechanism 6. At this time, the crawler body 2 is in a non-rotating state. Since the outer sides of the multiple secondary wheels 404 are covered with the crawler body 2, when the guide wheel frame body 101 rotates, the guide wheel frame body 101 drives the multiple fixed frames 104 and the corresponding connecting shafts 105 to rotate, thereby driving the multiple rotating frames 401, the movable frames 402 and the telescopic frames 403 to rotate, and then driving the multiple secondary wheels 404 to revolve. At this time, the multiple telescopic bars 305 are stationary, providing a corresponding The corresponding supporting force causes the track body 2 to revolve, thereby realizing the driving of the sled vehicle. When the track body 2 needs to be adjusted, multiple telescopic bars 305 extend outward, driving the connected telescopic frames 403 to extend outward. At the same time, multiple movable frames 402 rotate, thereby driving the positions of the connected secondary wheels 404 to shift. When the multiple telescopic bars 305 extend to the specified positions, the track body 2 is adjusted from a circle to a triangle, thereby increasing the contact area with the ground, making it more stable when driving on harsh ground. Multiple movable frames 402 are rotatably connected to the corresponding telescopic frames 403, and the outer sides of multiple secondary wheels 404 are fitted with the inner wall of the track body 2. When the track body 2 is circular or triangular, the track body 2 is tightly covered on the outer sides of multiple secondary wheels 404. When the track body 2 is circular, the track body 2 is not driven. When the track body 2 is triangular, the track body 2 is driven by the main guide wheel mechanism 5.

[0031] like Figure 1-Figure 10As shown, a main guide wheel mechanism 5 is installed on the outer top of the guide wheel frame assembly 1, and the main guide wheel mechanism 5 includes two main shafts 501 rotatably connected to one end of one of the telescopic frames 403, the outer ends of the two main shafts 501 are fixedly connected to the main wheels 502, the outer walls of the two main shafts 501 are fixedly connected to the corresponding main wheels 502, and the inner ends of the two main shafts 501 are fixedly connected to the first bevel gear 504, and the second motor 505 is installed at the center of one of the telescopic frames 403, and the outer wall of the output shaft of the second motor 505 is fixedly connected to the second bevel gear 506. When the crawler body 2 is adjusted to a triangle, the second motor 505 is started, and the second motor 505 drives the second bevel gear 506 to rotate through the rotation of the output shaft, so that the second bevel gear 506 drives the two first The bevel teeth 504 rotate, so that the two first bevel teeth 504 respectively drive the corresponding main shaft 501 to rotate, thereby driving the connected main wheel 502 and the driving gear 503 to rotate, thereby driving the two internal teeth 22 to rotate, realizing the rotation of the track body 2 (the multiple secondary wheels 404 do not revolve at this time), so that the sled can travel on harsh ground, and the second bevel teeth 506 are meshed with the two first bevel teeth 504. In the combined state, the two driving gears 503 are meshed with the corresponding internal teeth 22. When the adjustment mechanism 3 is adjusted, the circular track body 2 is changed into a triangle. At this time, the two groups of internal teeth 22 are respectively meshed with the corresponding driving gears 503, so that when the driving gear 503 rotates, the meshing internal teeth 22 are driven to rotate, thereby driving the track body 2 to rotate, and realizing the travel of the entire sled.

[0032] like Figure 1-Figure 9As shown, a driving mechanism 6 is installed at the rear end center of the guide wheel frame assembly 1, and the driving mechanism 6 includes a gear ring 601 fixedly connected to the rear end center of the guide wheel frame body 101, the rear end of the gear ring 601 is rotatably connected to the fixed shell 602, the rear end top of the fixed shell 602 is fixedly connected to a connecting seat 603, the rear end of the fixed shell 602 is provided with a third motor 604, the front end of the output shaft of the third motor 604 is fixedly connected to a driving shaft 605, the front end of the driving shaft 605 is fixedly connected to an elastic coupling 606, the front end of the elastic coupling 606 is fixedly connected to a first rotating shaft 607, the two sides of the first rotating shaft 607 are respectively provided with a second rotating shaft 608 and a third rotating shaft 609, and the outer sides of the second rotating shaft 608 and the third rotating shaft 609 are each provided with a plurality of fourth rotating shafts 610 , the outer walls of the first rotating shaft 607, the second rotating shaft 608, the third rotating shaft 609 and the plurality of fourth rotating shafts 610 are all fixedly connected with movable gears 611, a first connecting frame 612 is installed between the first rotating shaft 607 and the second rotating shaft 608, a second connecting frame 613 is installed between the first rotating shaft 607 and the third rotating shaft 609, and a third connecting frame 614 and a fourth connecting frame 615 are respectively installed between the plurality of fourth rotating shafts 610, and the front outer side of the fixed shell 602 is rotatably connected with two fifth rotating shafts 616, and the outer walls of the two fifth rotating shafts 616 are fixedly connected with limited gears 617, when the crawler body 2 is circular, the third motor 604 is started, and the driving shaft 605 is driven to rotate by the rotation of the output shaft, thereby driving the elastic coupling 606 and The first rotating shaft 607 rotates, so that the first rotating shaft 607 drives the connected movable gear 611 to rotate, thereby driving the connected multiple movable gears 611 to rotate with each other. When the outermost movable gear 611 rotates, it drives the ring gear 601 to rotate, so that the ring gear 601 drives the guide wheel frame body 101 to rotate, thereby driving the crawler body 2 to rotate (at this time, the multiple secondary wheels 404 revolve), so that the sled can travel on the ground with a good environment. At this time, the contact area between the crawler body 2 and the ground is small, resulting in relatively low friction, thereby greatly reducing the fuel consumption of the sled, thereby reducing the cost of use. The bottom end of the shock absorber 7 is fixedly connected to the connecting seat 603, and the third motor 604 is installed on the sled body. The multiple movable gears 611 are all meshed with each other, and the first connecting frame The first connecting frame 612 and the second connecting frame 613 are both rotatably connected to the first rotating shaft 607, the first connecting frame 612 and the second connecting frame 613 are rotatably connected, the first connecting frame 612 and the third connecting frame 614 are rotatably connected, the second connecting frame 613 and the fourth connecting frame 615 are rotatably connected, wherein the two fourth rotating shafts 610 are rotatably connected to the front end of the fixed shell 602. When the crawler body 2 is circular and the crawler body 2 travels on a convex or concave ground, the crawler body 2 is buffered by the fixed shell 602 under the action of the shock absorber 7. At the same time, the first connecting frame 612, the second connecting frame 613, the third connecting frame 614 and the fourth connecting frame 615 rotate with each other, and the multiple movable gears 611 inside them rotate in mesh with each other, so as to facilitate the buffering movement of the entire guide wheel frame.The traditional differential, gearbox and other components are omitted, which reduces the complexity of vehicle manufacturing, thereby reducing the failure rate and maintenance cost. In addition, each track body 2 is independently operated by the third motor 604, and the power distribution is more flexible, which greatly improves the driving stability of the sled vehicle.

[0033] The working principle of this embodiment is as follows. When the sled is traveling on a ground with a good environment, the crawler body 2 is circular and does not need to be adjusted. At this time, the third motor 604 is started, and the drive shaft 605 is driven to rotate by rotating the output shaft, thereby driving the elastic coupling 606 and the first rotating shaft 607 to rotate, so that the first rotating shaft 607 drives the connected movable gear 611 to rotate, thereby driving the connected multiple movable gears 611 to rotate with each other, and the outermost movable gear 611 rotates and drives the ring gear 601 to rotate, so that the ring gear 601 drives the guide wheel frame body 101 to rotate, so that the guide wheel frame body 101 drives multiple fixed frames 104 and corresponding connecting shafts 105 to rotate, thereby driving multiple rotating frames 401, movable frames 402 and telescopic frames 403 to rotate, and then driving multiple secondary wheels 404 to revolve. At this time, the multiple telescopic bars 305 are stationary, providing corresponding support strength, so that the crawler body 2 revolves, thereby driving the crawler body 2 to rotate (the multiple secondary wheels 404 revolve at this time); When the sled is traveling on a harsh ground, the track body 2 needs to be adjusted to a triangle position, and the first motor 301 is started. The output shaft rotates to drive the rotating disk 302 to rotate, thereby driving the multiple arc grooves 303 to rotate, thereby driving the multiple movable pins 304 to slide in the corresponding arc grooves 303. As the multiple telescopic bars 305 slide with the corresponding slide rails 102, the multiple telescopic bars 305 extend outward, driving the connected telescopic frames 403 to extend outward. At the same time, the multiple movable frames 402 rotate, thereby driving the position of the connected secondary wheels 404 to shift. When the multiple telescopic bars 305 extend to a specified position, the position of the secondary wheels 404 is shifted. When the track body 2 is in the right position, the track body 2 is adjusted from a circle to a triangle, thereby driving the secondary guide wheel mechanism 4 and the main guide wheel mechanism 5 to deform. At this time, the second motor 505 is started, and the second motor 505 drives the second bevel gear 506 to rotate through the output shaft, so that the second bevel gear 506 drives the two first bevel gears 504 to rotate, so that the two first bevel gears 504 respectively drive the corresponding main shaft 501 to rotate, thereby driving the connected main wheel 502 and the driving gear 503 to rotate, thereby driving the two internal teeth 22 to rotate, realizing the rotation of the track body 2 (the multiple secondary wheels 404 do not revolve at this time), so that the sled vehicle can travel on harsh ground.
