Description

[Detailed Description of the Invention] This invention relates to a motorcycle footstep that reduces vibration.

On a motorcycle, the footstep on which the rider places his or her feet is constructed by connecting the center of a footbar that extends laterally to the left and right at the bottom center of the vehicle body, and inserting cylindrical steps made of elastic material into both ends of the footbar. The driver places his/her feet on a cylindrical step. On the other hand, in a motorcycle, the engine is mounted in the lower center of the vehicle body, close to the cylindrical steps. The engine vibrates while driving
This vibration is transmitted to the foot bar via the vehicle body. Although the cylindrical step uses an elastic material to attenuate this vibration, the vibration is still transmitted to the foot and is uncomfortable.

This idea is an improvement based on these points.
Embodiments of the present invention shown in the drawings will be described below.

The foot bar 1 is made of steel bar, and is connected at the center to the lower part of the vehicle body 2 so that the left and right ends protrude laterally. The tubular body 3 made of a steel pipe is narrowed at its inner end to match the outer diameter of the foot bar 1, fitted into the tip of the foot bar 1, and the tubular body 3 is welded to the foot bar 1 at the narrowed end. Then, an elastic piece 4 is press-fitted between the tip of the foot bar 1 and the inner wall of the tube body 3. Also, tube body 3
A cylindrical step 5 made of an elastic material is press-fitted into the step. 6 is a reinforcing plate.

The effect will be explained.

Vibrations caused by engine operation are transmitted to the foot bar 1 via the vehicle body 2, and further transmitted to the tube body 3.
However, the transmission of vibration to the tube body 3 is first damped by the elastic piece 4. The vibrations transmitted to the tubular body 3 are further damped by the cylindrical step 5.

Therefore, the vibrations to the driver are attenuated in two stages by the elastic piece 4 and the cylindrical step 5, so the vibrations transmitted to the driver's feet are greatly reduced.

As explained above, this idea involves fitting a pipe body with a constricted inner end into the tip of a foot bar whose center is connected to the lower part of the vehicle body, and welding the constricted part to the foot bar, thereby connecting the tip of the foot bar and the inner wall of the tube body. Since an elastic piece is attached between the foot bar and a cylindrical step made of elastic material is inserted into the tube body, vibration can be damped in two stages by the elastic piece and the cylindrical step. Transmitted vibrations can be greatly reduced. In this way, vibrations to the feet of a driver who places his feet on the cylindrical step can be reduced.
