Referring to fig. 1-4, an improved mechanism based on the existing continuously variable transmission comprises a fixed frame 1, a transmission main shaft 2 is movably sleeved on the fixed frame 1, driving mechanisms 3 are respectively arranged at the front side and the rear side of the middle part of the outer surface of the transmission main shaft 2 and positioned in the inner cavity of the fixed frame 1, the inner part of a front driving mechanism 3 is fixedly sleeved with the outer surface of the transmission main shaft 2, the inner part of a rear driving mechanism 3 is movably sleeved with the outer surface of the transmission main shaft 2, a driven mechanism 4 is movably sleeved at the middle part of the left end of the fixed frame 1, and one end of the driven mechanism 4 is respectively contacted with one ends of two groups of driving mechanisms 3.
Wherein, for the arrangement of the driving mechanism 3 and the driven mechanism 4, a formula is utilizedIn the conical structure, when the angular speed is unchanged, the radius is larger, the linear speed is larger, so that the contact radius of the driven mechanism 4 is changed by changing the contact position of the driven mechanism 4 in the driving mechanism 3, the output rotating speed of the driven mechanism 4 is flexibly adjusted under the condition of ensuring that the rotating speed of the transmission main shaft 2 is unchanged, and continuous friction transmission is adopted between the driving mechanism 3 and the driven mechanism 4, thereby effectively avoiding the phenomenon of pause and contusion when the rotating speed of the driven mechanism 4 is adjusted, and having good stability and higher transmission efficiency.
The driving mechanism 3 and the transmission main shaft 2 are fixedly sleeved in the inner cavity of the fixed frame 1, so that the rotation moment of the transmission main shaft 2 is mainly transmitted to drive the driven mechanism 4 to rotate, the driving mechanism 3 and the transmission main shaft 2 are movably sleeved in the other group, so that the pressures at two ends of the driven mechanism 4 are balanced, the driven mechanism 4 can always keep a balanced state, the phenomenon of inclination in the transmission process is avoided, the abrasion of the driven mechanism 4 is effectively reduced, and the service life of the stepless speed change mechanism is prolonged.
In this technical scheme, initiative mechanism 3 includes hydraulic mechanism I31, and the inner wall of hydraulic mechanism I31 cup joints with the surface activity of transmission main shaft 2, and the one end fixed mounting of hydraulic mechanism I31 has toper dop I32, and one side of the surface of toper dop I32 is equipped with connection preforming I33.
The gap between the two groups of conical chucks I32 can be flexibly adjusted through the hydraulic mechanism I31 for the arrangement of the driving mechanism 3 so as to adjust the contact position between the driven mechanism 4 and the conical chucks I32, thereby flexibly and conveniently controlling the rotating speed of the driven mechanism 4 and realizing the continuous adjustment control of the rotating speed of the driven mechanism 4.
In this technical scheme, driven mechanism 4 includes driven main shaft 41, and driven main shaft 41's the fixed hydraulic mechanism II 42 that has cup jointed in one side of surface, the outer wall of hydraulic mechanism II 42 and the inside fixed connection of fixed frame 1 left end, the one end of hydraulic mechanism II 42 runs through and extends to the inside of fixed frame 1 and fixed mounting have toper dop II 43, the right-hand member of toper dop II 43 and the mutual joint between the connection preforming I33.
Wherein, to the setting of follower 4, utilize the setting of hydraulic mechanism II 42 to ensure that toper dop II 43 can remain all the time with the contact pressure between two sets of toper dop I32, make it can not appear the phenomenon of skidding in the in-process that drives toper dop II 43 rotation, further improved this continuously variable transmission's transmission efficiency and stability in the transmission process.

accelerating the mold section: when the rotation radius of the conical chuck I32 at the contact position is larger than the radius of the conical chuck II 43, the circumference is taken as a judging template, the rotation circumference of the conical chuck I32 is larger than the rotation circumference of the conical chuck II 43, so that the conical chuck II 43 rotates more than once when the conical chuck I32 rotates once, and the continuously variable transmission mechanism is in an accelerating state;
synchronizing the mold sections: when the rotation radius of the conical chuck I32 at the contact position is equal to the radius of the conical chuck II 43, the circumference is taken as a judging template, the rotation circumference of the conical chuck I32 is equal to the rotation circumference of the conical chuck II 43, so that when the conical chuck I32 rotates for one circle, the conical chuck II 43 also rotates for one circle, and the stepless speed change mechanism can be determined to be in a synchronous state;
and (3) a speed reduction die section: when the radius of rotation of the conical chuck I32 at the contact position is smaller than the radius of the conical chuck II 43, the circumference is taken as a judging template, the rotating circumference of the conical chuck I32 is smaller than the rotating circumference of the conical chuck II 43, so that the conical chuck II 43 cannot rotate for one circle when the conical chuck I32 rotates for one circle, and the continuously variable transmission mechanism can be determined to be in a decelerating state.
