In summary, the variable diameter wheel of the present invention is mounted on the input shaft, the input shaft, the drive ring support, the drive ring, the drive disc, the round rod slide plate on one side, the cylinder shaft, and the round rod on the other side. The slide rails form a rotating whole and can be rotated together by the input shaft. On the other hand, the cylinder shaft generates sufficient torque to drive the first rail support plate through a certain rotation of the scroll spring, and the first rail support plate can stably rotate on the cylinder shaft by the action of the sleeve, and the first rail support plate drives The rotation of the first spiral track, the rotation of the spiral track and the rotation of the slide rail of the round rod cause a phase difference due to the action of the scroll spring, causing the position of the runner to change in the track of the first spiral track, and the larger the phase difference, the runner The greater the change in position in the track, the radial distance of the first slider from the barrel axis. The first rail support plate simultaneously drives the second rail support plate at the other end through the cylinder wall, the end wall of the cylinder wall, and the inner shaft to drive the second spiral rail to rotate, thereby causing the position change of the corresponding runner; the design of the inner shaft starts from The action of the angles of rotation of the first spiral track and the second spiral track on both sides of the synchronous drive rod causes the two sides of the drive rod to receive the same force at the same time, so that the radial distance from the shaft is changed to achieve stable The purpose of changing the diameter. The length of the positioning plate used to drive the round bar is different because, for the position of the wheel in the spiral track, The radial distance of all the runners from the center of the spiral track is different. In order to ensure that the drive rods are co-circular, a positioning plate is needed to eliminate the influence of the spiral track.

The specific embodiment is as follows: when the input shaft does not rotate, the wheel formed by driving the round rod is at the maximum diameter; the input shaft starts to rotate, and when the acceleration of the input shaft rotation is small or the torque received by the input shaft is small, the scroll spring occurs. The smaller deformation can drive the first rail support plate and the second rail support plate through the cylinder shaft, and the phase difference between the first rail support plate, the second rail support plate and the round bar slide plate is small, and the runner is on the spiral track. The change in position is small, the radial distance changes little, and the diameter of the variable diameter wheel changes little; when the torque of the input shaft is large, the scroll spring needs a large deformation to ensure the first rail support Keeping up with the rotation speed of the round rail slide plate, the phase difference will be large at this time, the distance of the radial movement of the rotary ring is large, the radial distance of the drive round rod from the cylinder axis is greatly reduced, and the diameter of the variable diameter wheel becomes smaller. The amplitude is very large; that is, when the driving torque or acceleration of the input shaft is large, the diameter of the variable diameter wheel is reduced. As the driving pulley, the rotation speed of the input shaft and the output shaft is relatively small, so that the output shaft is easier to drive, and the output shaft is obtained. Torque ; If this variable diameter of the wheel and the wheel with a fixed diameter is used as a motor vehicle transmission, then the acceleration or uphill overtaking, car will automatically obtain larger torque and acceleration. Has a higher use effect.
