Embodiment Construction
[0009] Such as figure 1 figure 2 As shown, the present invention consists of two parts, including input buffer storage A, impact variable diameter torque lock B, output buffer storage C. The input drive disc 1, the input storage spring 2 and the input driven disc 3 constitute the input Buffer storage A. The input driven plate 3 is connected by the rocker shaft 4 and the rocker arm 5 in the impact variable diameter torque lock B. The rocker arm 5 and the roller 6 on the outside of the rocker arm are placed in the cam sleeve 7, and the roller 6 is aligned with the inner track of the cam sleeve. The outer track of the cam sleeve is attached to the one-way locking roller 10, and the one-way locking roller 10 is attached to the groove in the fixed sleeve 11 connected to the shell to form an impact variable diameter torsion lock B. The cam sleeve 7 is connected with the output driving disc as a whole, and the output energy storage spring 8 and the output driven disc 9 form an output b...

A mechanical continuously variable transmission that does not rely on the traditional force arm adjustment principle. It consists of three parts: input buffer energy storage, impact variable diameter torque lock, and output buffer energy storage. For automobiles or other machines adopting the mechanical continuously variable transmission, when the resistance is greater than the input torque, the input shaft drives the input buffer energy storage to make the roller on the rocker arm perform impact and diameter-reducing rotation along the involute cam track. The impact makes the roller obtain greater acceleration, so that the cam sleeve overcomes the impact and performs step rotation. The one-way locking roller prevents the cam sleeve from reversing, so that the cam sleeve gradually compresses the output energy storage spring. When the potential energy of the output energy storage spring is greater than the resistance, the output shaft is accelerated smoothly. The present invention is suitable for any machinery that requires inaccurate output speed, and can be used as a shaft coupling of heavy machinery. The purpose of the invention is to provide a mechanical continuously variable transmission with large transmission torque, which can automatically and accurately adjust the torque output according to the change of resistance.
Description
Technical field [0001] The invention relates to a mechanical continuously variable transmission Background technique [0002] Mechanical continuously variable transmission has the characteristics of energy saving and fast acceleration. It is the first choice for many transportation gearboxes. However, due to its complex structure, small transmission torque, and narrow transmission range, it cannot be widely adopted. Summary of the invention [0003] The purpose of the present invention is to provide a mechanical continuously variable transmission with a large transmission torque, a variable speed range of 1:≤1, a speed ratio equal to the number of impacts: the displacement distance of the impact cam, and the output torque can be automatically adjusted according to changes in resistance. [0004] The mechanical continuously variable transmission of the present invention. It consists of three parts: input buffer energy storage, impact variable diameter torque lock, and output buff...
