Problems solved by technology

[0003] The disadvantage of the traditional pulsating continuously variable transmission is limited by the carrying capacity and impact resistance of the one-way overrunning clutch, the output mechanism has become a fatal flaw of the traditional pulsating continuously variable transmission, so it can only be applied to low-speed, medium and small power
Moreover, the one-way overrunning clutch can only output the power of the transmission mechanism with the largest instantaneous angular velocity, and the pulsation is relatively large. The method of increasing the number of phases of the combination mechanism to reduce the pulsation will also make the structure of the pulsation continuously variable transmission more complicated.

Abstract

The invention relates to a impulse non-stepped speed changer, wherein, one end of transmission is connected to the input axle, and another end is connected to the input axle to seal two central wheels of 2Z-X type positive taper gear differential wheel system whose closed transmission rate is 1:1; it uses rotational arm to output power and stepped output the power via two combined devices with 180 degree phase difference. The invention has overcome the defect the of traditional impulse non-stepped speed changer, with reasonable structure, simple control, high economic benefit, high loading ability, wider speed change rage, stable output torque, and the application for high-speed large power vehicle speed change system.

Description

technical field [0001] The invention relates to a mechanical continuously variable transmission, in particular to a pulse continuously variable transmission. Background technique [0002] As we all know, the traditional pulsating continuously variable transmission uses a transmission mechanism to convert the uniform rotational motion of the transmission main shaft into a variable speed rotational motion applied to the one-way overrunning clutch, and then convert it into a one-way pulsating rotational motion of the output shaft through the one-way overrunning clutch; Through several combined mechanisms with a certain phase difference, the output shaft obtains unidirectional rotary motion with small pulse amplitude. Use the speed regulating mechanism to change the length of a certain component in the transmission mechanism or change the eccentricity of a certain component to form a new size proportional relationship between the components, thereby changing the angular velocity...
