Problems solved by technology

[0002] The failure of transmission elements and pressurization devices is the two major factors that limit the transmission capacity of mechanical continuously variable transmissions. The transmission elements and pressurization devices of closed-type continuously variable transmissions are made of high-hardness alloy steel, and the usual form of failure is contact fatigue. Pitting corrosion and wear, and glue failure will also occur at high speeds, resulting in vibration, impact and noise, and ultimately can not work

Embodiment Construction

[0014] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0015] refer to figure 1 , 2 , the present embodiment provides the main structure of a new continuously variable transmission device, including a power input shaft 1 , an automatic pressurization device 2 , a set of steel balls 3 , and a power output shaft 4 .

[0016] The shaft wheel of the power input shaft 1 is connected with the shaft wheel of the power output shaft 4 through a group of steel balls 3, and an automatic pressurizing device 2 is installed on the group of steel balls 3.

[0017] Depend on figure 1 It can be seen that the power is input by the shaft 1 to drive the driving wheel to rotate, and the power output shaft 4 is driven to rotate through the automatic pressurizing device 2 and a group of steel balls 3 . The steel ball 3 can change the angle and position to adjust the output speed and torque of the driven wheel of the power outp...

Abstract

The invention relates to a continuously variable transmission device. The continuously variable transmission device is provided with a power input shaft used for inputting power and a power output shaft used for outputting the power. An arbor wheel of the power input shaft is connected with an arbor wheel of the power output shaft through a set of steel balls, and when the angle and the position between the power input shaft and the power output shaft are changed, the output speed of the power output shaft is adjusted. Automatic pressurization devices are installed on the set of steel balls and are used for increasing the contact friction force between the steel balls and the arbor wheel of the power input shaft 1 as well as the arbor wheel of the power output shaft, and slipping in the transmission process is prevented. According to the continuously variable transmission device, the output rotation speed can be changed according to the input rotation speed under the condition that the angle and the position of the steel balls are changed, and the effect of continuously variable transmission is achieved. Most importantly, very small grooves are formed in transmission wheels, and the steel balls are in line contact with driving wheels and the driven wheels, so that transmission expiration is prevented to a great extent and the service life of a transmission is prolonged.

Description

technical field [0001] The present invention relates to a transmission, and more specifically, to a continuously variable transmission device. Background technique [0002] The failure of transmission elements and pressurization devices is the two major factors that limit the transmission capacity of mechanical continuously variable transmissions. The transmission elements and pressurization devices of closed-type continuously variable transmissions are made of high-hardness alloy steel, and the usual form of failure is contact fatigue. Pitting corrosion and wear, and gluing failure will also occur at high speeds, resulting in vibration, impact and noise, and ultimately can not work. The open mechanical continuously variable transmission is usually made of steel-cast iron transmission parts, the friction coefficient of the device is relatively large, and the main failure mode is the wear caused by sliding and the burn caused by poor heat dissipation. Therefore, it is necess...
