Hybrid stepless speed change mechanism

Abstract

This invention relates to a mixed stepless drive composed of a tank, a input shaft, output shaft, a speed variable device, a control device and an operating unit characterizing that: the speed variable device is made up of gears with special gears, inner rotor gear and outer rotor gear are always at clutching state either operating or stopping with the help of eccentric sleeve shaft and valve buckle, matched by the control device and operating unit, and the relative clutching positions remains unchanged, speed variable function is finished by relative rotating or stopping between gears which transfer smoothly and can be adjusted freely from 1:0 to 1:1 without fixed ratio.

Description

technical field [0001] The invention relates to machinery, in particular to a hybrid continuously variable speed change mechanism, especially a speed change mechanism with relatively wide transmission speed, stepless and smooth transition, adjustable and controllable during work. Background technique [0002] At present, there are many transmission mechanisms sold and applied in the market. Among similar products, hydraulic torque converters and hydraulic couplings are widely used, which belong to non-contact centrifugal continuously variable transmission devices. Oil, theoretically speaking, its transmission speed ratio is smoothly transitioned from 1:0 to 1:1, but it is impossible in actual working conditions, the highest can reach 1:0.9 or a little higher, but this is not important, It can be overcome by designing the transmission speed ratio. The main problem is determined by the working principle of this transmission mechanism. First of all, the product processing accur...

[0002] At present, there are many transmission mechanisms sold and applied in the market. Among similar products, hydraulic torque converters and hydraulic couplings are widely used, which belong to non-contact centrifugal continuously variable transmission devices. Oil, theoretically speaking, its transmission speed ratio is smoothly transitioned from 1:0 to 1:1, but it is impossible in actual working conditions, the highest can reach 1:0.9 or a little higher, but this is not important, It can be overcome by designing the transmission speed ratio. The main problem is determined by the working principle of this transmission mechanism. First of all, the product processing accuracy is high, there is no contact between the driving wheel, the guide wheel and the driven wheel, and the working gap is very small. The shape, size and smoothness of the working blades on each working wheel are very high, and must be processed by special equipment, so the processing cost is very high, so the cost of the processed parts of this product is greatly increased, resulting in high processing cost of the speed change mechanism In addition to the cost of other types of speed change mechanism; in addition, the working principle of this kind of speed change mechanism is the principle of centrifugal work, so when it works at low speed, the work efficiency is also very low. When this speed change mechanism is used in low speed work occasions, it needs An additional set of speed change device is mainly used in the automobile industry, and because of its high cost, it is mainly used in high-end cars and some special vehicles; In addition to the complexity and high cost, the transmission speed ratio is limited, so it has only been applied to a small number of special machine tools so far; in view of the shortcomings of the above two transmission mechanisms, it is urgent to provide a simple structure, low machining accuracy, and low cost. Greatly reduced, wide transmission speed ratio, stepless smooth transition, and a transmission mechanism that can be adjusted and controlled during work
