  According to the above auxiliary device, it is said that the slip of the front wheel 3 can be suppressed, but even if this auxiliary device is used, the front wheel 3 and the rear wheel 6 eventually run on the snow. .

  For example, when running on snow when the snow is fresh, generally, the front wheels and the rear wheels sink into the snow due to the weight of the two-wheeled vehicle 1, so that the snow acts as a resistance to the front wheels. For this reason, it is quite difficult to run even at a low speed, and in the worst case, it may become impossible to run.

  In such a case, the sliding plate 30 of the auxiliary device shown in FIG. 10 has only a function of sliding on the snow, so it can be an effective means when the front and rear wheels sink into the snow. Absent.

  The present invention has been made in view of the problems in the conventional auxiliary device for running on snow, and even if the front and rear wheels of a two-wheeled vehicle sink into the snow, An object of the present invention is to provide a snow removal device as a snow travel assistance device for a two-wheeled vehicle that enables traveling on snow.

  In order to achieve the above object, the present invention is a snow removal device for a motorcycle comprising at least one link member and at least one snow remover, wherein the link member is attached to and detached from the motorcycle at one end thereof. The snow remover is freely attached, and is connected to the snow remover at the other end so that the snow remover is located in front of at least one of the front wheel and the rear wheel of the two-wheeled vehicle, and the outer peripheral surface of the snow remover projects forward. A snow removal device is provided which is V-shaped.

  It is preferable that the bottom side of the snowplow is inclined so that the tip of the bottom side is located above the traveling path and the rear end of the bottom side is located above the tip.

  The link member is rotatably attached to the two-wheeled vehicle, and the snow remover is positioned in front of at least one of the front wheel and the rear wheel, and the snow remover is in the first position. It is preferable to be able to rotate between a second position located above.

  The link member is preferably attached at one end thereof to at least one of the front wheel and the rear wheel of the motorcycle.

  It is preferable that the link member includes a first link member that extends obliquely upward and forward from the axle, and a second link member that connects the first link member and the snow remover.

  The link member includes a first link member extending forward of the axle, a second link member connecting the first link member and the snow remover, and an urging member, and the second link member is It is preferable that the first link member is rotatable, and the biasing member biases the second link member toward the rear of the two-wheeled vehicle.

  The snow removal device preferably includes an urging member that urges the snow remover downward toward the traveling path.

  The snow remover comprises a first part including a tip of the bottom of the snow remover and a second part including a rear end of the bottom, and the first part is centered on a rear lower end thereof with respect to the second part. It is preferable to include a biasing member that is attached to the second part so as to be rotatable, and biases the first part in a direction in which the first part pivots upward.

  It is preferable that at least the tip of the bottom of the snow remover is made of hard rubber.

  The present invention further provides a two-wheeled vehicle in which the snow removal device described above is attached in front of at least one of a front wheel and a rear wheel.

  The snow remover in the snow removal device according to the present invention is attached in front of one or both of the front wheel and the rear wheel of the motorcycle. When running on a snowy road (especially a fresh snowy snowy road) with a snowplow attached, the snowboard on the road is removed by the snowplow because the front edge of the snowplow has a convex V-shape. It is divided into two parts, and snow is removed on both the left and right sides of the snow remover as the motorcycle runs.

  As described above, according to the snow removal device of the present invention, the two-wheeled vehicle can travel on the traveling road from which snow has been removed. As described above, when traveling on a road on which fresh snow is piled up, the front wheels and the rear wheels may sink into the snow, resulting in an inability to travel, but the snow removal device according to the present invention is applied to a motorcycle.

  The first portion 351 and the second portion 352 of the snow remover 350 are configured to be rotatable with respect to each other about the lower ends 351A and 352A. For this reason, as shown in FIG. 7B, when the first portion 351 of the snow remover 350 collides with the stone 131, the first portion 351 resists the tensile force of the tension spring 353 due to the impact. On the other hand, it rotates in the direction of arrow X1 (downward direction).

  After that, as shown in FIG. 7C, the first portion 351 is repelled upward while maintaining the state of rotating with respect to the second portion 352 and in contact with the stone 131.

  The first portion 351 that is repelled upward travels forward as it is, and as a result, the first portion 351 is over the stone 131 as shown in FIG. At this time, since the contact state with the stone 131 that maintained the rotation state of the first portion 351 with respect to the second portion 352 has been eliminated, the first portion 351 receives the tensile force of the tension spring 353 and moves upward. It rotates (in the direction opposite to the arrow X1) and returns to the original state (the state shown in FIG. 7A).

  As described above, in the snow removal device according to the present embodiment, the snow removal device 350 has a function of getting over stones and other obstacles on the traveling road 130. For this reason, compared with the snow removal apparatus 100, 100A, 200 which concerns on 1st thru | or 3rd embodiment, it is possible to avoid damage to the snow remover 350 dramatically.

And a second link member 463 that connects the other end of 462 and the snow remover 150.

  For example, it is assumed that the snowplow 150A collides with a stone on the traveling road 130 and an impact force acts on the snowplow 150A. In this case, the impact force is divided into a first force component that pushes the snow remover 150 </ b> A rearward and a second force component that is transmitted obliquely upward along the second link member 463. The second force component pushes the second link member 463 upward along the central axis of the second link member 463. When the second link member 463 is pushed upward by the second force component, the first link member 462 is connected to the second link member 463 at one end thereof, so that the first link member 462 is the axle 171 of the front wheel 170. Is subjected to a force (rotational moment) that rotates in the direction of the arrow C with respect to the center.

  Therefore, the second force component is canceled when the first link member 462 rotates in the direction of arrow C about the axle 171 of the front wheel 170.

  In this way, by configuring the link member 460 from the first link member 462 and the second link member 463, even if an impact force acts on the snowplow 150A, the second link member 463 is transmitted out of the impact force. The second force component is absorbed when the first link member 462 rotates around the axle shaft 171.

  That is, according to the snow removal device 400 according to the present embodiment, even if an impact force acts on the snow remover 150A during traveling, the impact force can be attenuated, and the risk of damage to the snow remover 150A is reduced. can do.

  The second link member 563 is connected to the first link member 562 so as to be rotatable, and is rotatable in both the clockwise direction D and the counterclockwise direction C with respect to the first link member 562.

  The spring member 564 is stretched between the first link member 562 and the second link member 563, and the second link member 563 is rotated when the second link member 563 rotates in the clockwise direction D with respect to the first link member 562. The two link members 563 rotate counterclockwise C with respect to the first link member 562 and urge the second link member 563 so as to return to the initial position.

  For example, it is assumed that the snowplow 150A collides with a stone on the traveling road 130 and an impact force acts on the snowplow 150A. In this case, since the snow remover 150A is pushed rearward by the impact force, the second link member 563 connected to the snow remover 150A rotates in the clockwise direction D with respect to the first link member 562. When the second link member 563 is rotated clockwise D to completely absorb the total impact force received by the snow remover 150A, it is rotated counterclockwise C by the biasing force of the spring member 564, and the original Return to the position (position shown in FIG. 8).

  Thus, even if an impact force acts on the snow remover 150A by configuring the link member 560 from the first link member 562, the second link member 563, and the spring member 564, the impact force is applied to the second link member. 563 is absorbed by rotating around the first link member 562.
