Definitions
- the present invention relates to a pulley that is responsible for the shifting of a V-belt continuously variable transmission.
- a V-belt continuously variable transmission continuously changes the rotation diameter of the input shaft and the output shaft of the drive belt by an operation of changing the distance between the side plates installed on the input shaft and the output shaft pulley. Shifting is in progress.
- the input shaft pulley and the output shaft pulley are composed of one movable side plate 2 movable in the axial direction and one fixed side plate 1 fixed to the rotating shaft 5, FIG movable pulley input shaft in the speed change process as illustrated in the side plate 2 and the drive belt according to shrink into the L 'in the distance of the fixed side plate (1), L (3) is at the same time the drive belt as soon extends to the outer periphery of the pulley The operating center moves in the diagonal direction of the drive shaft with an axial displacement dL .
- the present invention is to improve the operation of the drive belt according to the shifting process of the V-belt continuously variable transmission.
- the pulleys installed on the input shaft and the output shaft of the conventional V-belt continuously variable transmission consist of one movable side plate and drive belt in the shifting process. Is to prevent movement in the direction of the fixed side plate.
- the driving belt should be operated at the same position in the axial direction of the input shaft and the output shaft, but the phase difference occurs in the driving belt in the direction of the driving shaft from the input shaft and the output shaft due to the frictional force and the power transmission load caused by the rotation of the driving belt.
- the pulley and the friction surface are reduced, which reduces the power transmission efficiency and causes vibration and noise to the transmission and weakens the durability of the drive belt.
- the purpose of this is to prevent the drive belt from moving in the direction of the drive shaft in the shifting process of the V-belt continuously variable transmission, thereby increasing the efficiency of power transmission.
- the problem is that the drive belt is improved even if the distance between the input shaft and the output shaft pulley is changed during the shifting of the continuously variable transmission by improving the shape of the pulley so that the driving belt moves only in the direction perpendicular to the input shaft and the output shaft during the shifting process of the belt type CVT. This can be solved by not having axial displacement and deformation.
- the drive belt since the driving belt reduces displacement and deformation in the direction of the drive shaft, the drive belt is integrated with the input shaft and the output shaft pulley to transmit power, thereby reducing the shift time delay and power system. It can reduce vibration and increase the efficiency of power transmission.
- the input shaft pulley and output shaft pulley are composed of two symmetrical movable side plates so that the same pressure can be operated in both directions around the driving belt according to the change of the rotational speed of the drive system so that the operation center of the drive belt does not change during the continuously variable transmission.
- the improved pulley according to the present invention is equipped with two movable side plates 21 around the drive belt 3 as shown in FIG. 6, and two movable side plates 21 in the shifting process as shown in FIG. 7.
- Infinite gearbox with double movable side pulley is applied to drive shaft without moving in axial direction even if there is a time delay when power transmission load is generated during shifting and pulleys installed on input shaft 4 and output shaft 5 do not operate simultaneously. It works only in the direction perpendicular to.
- the pair of movable side plates 21 which operate symmetrically, the driving belt operates at the center of the input shaft and the output shaft pulley, thereby reducing vibration and noise of the V-belt continuously variable transmission and improving power transmission efficiency.
