Problems solved by technology

The moving cone of the active cone wheel is set on the side of the forward clutch, and an electro-hydraulic control cone force cylinder is set between the moving cone and the forward clutch. This design layout forces the metal transmission belt assembly to move outward axially. , the axial size of the whole machine increases, and it is difficult to arrange when the transverse engine is driven by the front wheel

Embodiment Construction

[0009] The embodiment given in conjunction with the accompanying drawings further illustrates that the engine output shaft 1 is linked with the forward gear clutch frame provided in the transmission book, and the power is transmitted to the oil pump 19 through the sprocket drive pair 18, and the forward gear clutch hub is connected with the gearbox main shaft 9, The active cone wheel linkage, the active cone wheel includes a fixed cone 6 and a moving cone 7 oppositely arranged, the fixed cone 6 is located on one side of the forward gear clutch 5, and the outside of the moving cone 7 of the driving wheel is provided with a pressure cylinder 8, and the same The driven cone wheel also includes a fixed cone 12, a moving cone 11 and a pressure cylinder 13 which are arranged oppositely. The axial distance between the two conical discs of the disc wheel makes the metal conveyor belt assembly 10 move radially, thereby changing the transmission radius of the driving and driven conical d...

Abstract

The stepless variable drive mainly includes reverse brake and forward gear clutch which are placed in the gear shifting box, driving cone disk wheel, driven cond disk wheel and metal driving strap component, in which the driving and driven cone disk wheels are respectively formed from a fixed cone disk and axially-movable cond disk which are oppositely arranged. It is characterized by that the input portion of forward gear clutch is coupled with output shaft of engine, the output portino of forward gear clutch is coupled with driving cone disk wheel, the fixed cone disk of the driving cone disk wheel is set at one side of forward gear clutch, and the forward gear clutch is a wet friction clutch in which the pressure can be progressively applied by chip microprocessor controlled hydraulic system according to set control curve instead of main clutch function in car driving chain.

Description

Technical field: [0001] The invention relates to transmission technology, and proposes a continuously variable transmission device. Mainly used in automobile variable speed transmission, also suitable for other mechanical variable speed transmission. Background technique: [0002] Usually, the transmission mode of continuously variable transmission is variable pitch circle mode, that is, the driving conical disc wheel includes a fixed conical disc and a movable conical disc that can move axially, and the driven conical disc wheel includes a fixed conical disc and a movable conical disc that can move axially. Cone disc, the metal transmission belt assembly connects the main and driven conical disc wheels to form a belt transmission pair, controls and changes the axial distance between the two conical discs of the conical disc wheel, and makes the radial displacement of the metal conveyor belt assembly, thereby changing the driving and driven conical disc wheel. The transmiss...
