JP5497950B1 - Stabilizer for motorcycle running on curve with auxiliary wheel - Google Patents

Abstract

In a motorcycle, it is possible to stabilize curve running under bad conditions such as rain, snow, and strong wind.
A motorcycle is equipped with a horizontal wing and a vertical wing as a three-wheel configuration using auxiliary wheels on a side surface of a motorcycle, and a curved traveling is stabilized by using lift generated in each.

Description

  The present invention relates to a stabilizer for a motorcycle traveling in a curve under bad conditions such as rain, snow, and strong wind.

  Conventionally, in order to prevent overturning, which is a drawback of motorcycles, it has been solved by installing a sidecar.

  Japanese Patent No. 3027265   Japanese Utility Model Publication No. 50-7641

  In the prior art documents, when driving in a curve toward a side wheel of a motorcycle with a side car, a heavy load is added to prevent the side wheel from lifting due to an increasing centrifugal force, or an auxiliary wheel is attached to the vehicle body tilted by the increasing centrifugal force. Is installed on the opposite side of the side wheels to support the car body.

  In motorcycles, when the vehicle is running on a curve, the vehicle falls over when either the front wheel or the rear wheel slips, but by installing a sidecar, the grounding point becomes 3 points and slips against rain, snow, muddy water, etc. Can prevent falls.

  However, motorcycles with side cars are very expensive.

  In addition, if the vehicle weight increases, both the performance and fuel consumption decrease.

  In addition, because the air resistance of the sidecar is large, at high speeds or when the head wind is strong, the ground contact pressure of the front wheels decreases and running becomes unstable.

  In order to solve the above-described problems, the present invention includes a motorcycle equipped with a horizontal wing that generates a downward lift attached by a connecting member on one side of the center of gravity when not riding, and an auxiliary wheel is attached to the tip of the wing. A configuration where the outer shape of the upper part of the ring mudguard cover is a vertical wing with a rudder.

  A vertical wing with a rudder can generate lift from the left and right by turning the rudder left and right, and is used as a centripetal force against the centrifugal force generated on the left and right curves.

  Compared to a motorcycle with a sidecar, it is extremely lightweight, so it has improved performance and fuel efficiency and is inexpensive.

  Since the point of action of the downward lift of the horizontal wing is in front of the center of gravity when boarding, even at high speeds when the air resistance increases or when the headwind is strong, the ground contact pressure of the front wheels does not decrease and stable curve driving can be performed .

  When driving at low speeds, the effect of lift is small, so tilting the upper body to cope with centrifugal force, but the weight of the driver is overwhelmingly light compared to motorcycles with sidecars, so the effect of the driver's weight shift Can be run without turning the auxiliary wheel in both the clockwise and counterclockwise directions.

  Since the lift of the vertical wing assists the centripetal force by the tire as the centripetal force, the steering angle of the steering wheel can be reduced and the burden on the tire is reduced.

  In addition, since the point of action of lift is at the upper part of the auxiliary wheel, it is possible to effectively correct the inclination of the vehicle body due to the centrifugal force generated during curve driving.

  [0009] The configuration of the stabilization device during the curve running of the motorcycle with the auxiliary wheel is the configuration according to [0009].

  The present invention will be described below with reference to the drawings.

  When driving on the right curve at 50 km / h.

  When the lever 6 in FIG. 2 is moved to the right in the traveling direction, the rod 7 changes the angle to the right in the traveling direction by the rod 7, and lift is generated on the right side.

  At this time, tilt the upper body to the right and simultaneously turn the handle to the right to pass the curve.

  After passing the curve, return the handle and simultaneously return the upper body and return the lever 6 to neutral.

  Next, when driving on the left curve at 50 km / h.

  When the lever 6 in FIG. 2 is moved to the left in the direction of travel, the rod 7 changes the angle of the rudder 4 to the left in the direction of travel, and lift occurs on the left side.

  At this time, tilt the upper body to the left and simultaneously turn the handle to the left to pass the curve.

  After passing the curve, return the handle and simultaneously return the upper body and return the lever 6 to neutral.
