Abstract

PURPOSE:To carry out speed control easily by making a running body run while changing gear in two stages when the running body with a built-in motor rotated by feeding the power from a conductive rail runs on a track. CONSTITUTION:The one-way clutch mechanism of the first reduction gear train A can release the linking condition of the rotary shaft 2 of a motor 1 and a drive shaft 15 when the rotary shaft 2 is rotated in the reverse direction, and the one-way clutch mechanism of the second reduction gear B can release the linking condition of the rotary shaft 2 and the drive shaft when the rotary shaft 2 of the motor 1 is rotated in the right direction. And a running body is run while changing gear in two stages by the right and the reverse rotations of the rotary shaft 2 of the motor 1. As a result, the first and the second reduction gear trains A and B having different gear ratioes are used by converting adequately each other in the running on a straight part or a corner with relatively a larger curvature radius, and on a corner with relatively a small curvature radius. Consequently, speed control can be carried out easily.

Description

Detailed Description of the Invention (Industrial Application Field) The present invention is characterized in that when a traveling body having a built-in motor that is rotated by electricity supplied from a conductive rail travels on a track, it travels while changing gears in two stages. This invention relates to a transmission device for a toy that travels on tracks.

(Prior art) Conventionally, in this type of track running toy, the rotation speed of the built-in motor is controlled by operating a speed controller to control the current supplied to the running body from the conductive rail. They enjoy adjusting the running speed of the running object and making sure that it does not deviate from the running trajectory.

(Problem to be Solved by the Invention) However, in a running object, the gear ratio is always constant until the rotational force of the motor is transmitted to the drive wheels, and this gear ratio is usually set so that the maximum speed can be achieved. Since the speed controller is set to be suitable for driving in a straight section, for example, when driving around a corner, if you do not operate the speed controller properly, your driving speed may drop drastically.
Another problem is that the traveling object easily deviates from the traveling trajectory due to overspeeding. Moreover, delicate operation of the speed controller when driving around this corner required great skill and was difficult.

(Means for Solving the Problems) Therefore, the present invention was created to solve the above-mentioned problems, etc. Specifically, the present invention has a built-in motor 1 that is rotated by being supplied with electricity from a conductive rail on a track. In a running body S of a track running toy that can run along a track, when the rotating shaft 2 of the motor 1 rotates in the forward direction, this rotational force is transmitted to the drive shaft 15 to which the drive wheels 17 are fixed. When the rotation shaft 2 of the motor 1 rotates in the reverse direction, the first reduction gear train A rotates in the forward direction, and when the rotary shaft 2 of the motor 1 rotates in the reverse direction, the rotational force is transmitted to cause the drive shaft 15 to rotate in the forward direction. A second reduction gear train B is provided. Then, the first reduction gear train A and the second reduction gear train B are each provided with a one-way clutch mechanism. Furthermore, the one-way clutch mechanism of the first reduction gear train A is configured to be able to release the connection between the rotating shaft 2 and the drive shaft 15 when the rotating shaft 2 of the motor 1 rotates in the reverse direction. Further, the one-way clutch mechanism of the second reduction gear train B is formed so as to be able to release the connection between the rotating shaft 2 and the drive shaft 15 when the rotating shaft 2 of the motor 1 rotates in the forward direction. Further, a means is adopted in which the traveling body S can travel while changing gears in two stages by forward and reverse rotation of the rotating shaft 2 of the motor 1.

(Function) Therefore, when the rotation shaft 2 of the motor 1 is rotated in the forward direction, the rotational force of the rotation shaft 2 is transmitted to the drive wheel 17 via the first reduction gear train A, causing the drive shaft 15 to rotate in the forward direction. ,
The second reduction gear train B does not transmit the rotational force of the rotary shaft 2 to the drive shaft 15 due to the function of its one-way clutch mechanism.

Furthermore, when the rotating shaft 2 of the motor 1 is rotated in the opposite direction, the rotational force of the rotating shaft 2 is transmitted to the drive wheels 1 through the second reduction gear train B.
7 to rotate the drive shaft 15 in the forward direction.
The reduction gear train A does not transmit the rotational force of the rotary shaft 2 to the drive shaft 15 due to the function of its one-way clutch mechanism. Moreover, the drive shaft 15 is connected to the first reduction gear train A.
Due to the difference in the gear ratio between when the rotating shaft 2 is rotated through the second reduction gear train B and when it is rotated through the second reduction gear train B, even if the rotational speed of the rotating shaft 2 is constant, it rotates at different rotational speeds. I come to do it.
