Problems solved by technology

[0002] In the prior art, continuously variable transmissions for vehicles, such as CVT, use friction transmission, and the power transmission is not as good as gear transmissions
And the stepless transmission that adopts gear transmission, as described in the utility model CN201739449U, replaces the clutch and the brake in the gearbox with a speed regulating device; its disadvantage is that the speed regulating device has a heavy load and needs sufficient hydraulic or electric power support
In fact, friction transmission and gear transmission have their own strengths and weaknesses, and it is difficult to balance

Embodiment Construction

[0027] Such as figure 1 As shown, the drive shaft 1, the central gear 2, and the transmission disc 8 are fixedly connected; the planetary gear shaft 3 and the worm wheel 7 are fixedly connected, and the worm wheel 7 acts as a support for the planetary gear; the friction wheel 9 includes a guide sleeve and a wheel fixed on the guide sleeve The friction wheel and the control rod can slide on the guide rod 10 and rotate synchronously with the guide rod 10; the guide rod 10 drives the worm 6 through the transition of the bevel gear. The friction wheel 9 is tightly pressed on the disc surface of the transmission disc 8, and rotates together with the transmission disc 8; the speed changes accordingly when sliding on the guide rod 10; the worm wheel 7 is driven to rotate through the guide rod 10 and the worm 6, and the planetary gear shaft 3 revolutions; at the same time, the planetary gear 4 rotates, transmits the power from the sun gear 2, and drives the driven wheel 5 to rotate. ...

Abstract

The invention relates to a mechanical transmission, in particular to an infinitely variable transmission for a planetary gear. The infinitely variable transmission mainly comprises one group of planetary gears, a worm gear, a worm, a friction transmission and the like, wherein a star wheel bracket is fixedly connected with the worm gear; and the transmission is used for controlling the rotating speed of the worm; and a planetary gear set is an execution device for the transmission. The infinitely variable transmission can be realized while high-power driving is carried out and the skidding is avoided. The infinitely variable transmission is wide in variable range and high in overload capacity. The infinitely variable transmission has respective advantages of vehicular CVT (Continuously Variable Transmission) and transmission gear boxes and is simpler and more reliable.

Description

technical field [0001] The invention relates to a mechanical transmission, in particular to a continuously variable transmission involving planetary gears. Background technique [0002] In the prior art, continuously variable transmissions for vehicles, such as CVT, adopt a friction transmission mode, and the power transmission is not as good as that of a gear transmission. And the stepless transmission that adopts gear transmission, as described in the utility model CN201739449U, replaces the clutch and the brake in the gearbox with a speed regulating device; its disadvantage is that the speed regulating device has a heavy load and needs sufficient hydraulic or electric power support . In fact, both friction transmission and gear transmission have their own strengths and weaknesses, and it is difficult to take into account both. Contents of the invention [0003] The object of the present invention is to provide a continuously variable transmission with simple structure...
