Embodiment Construction

[0015] The present invention is further described in detail below by way of examples and accompanying drawings.

[0016] Such as Figure 3-4 As shown, the present invention is a continuously variable speed structure composed of a mechanical pressurization and a speed regulating mechanism 2 through a pressure plate 15, a pressurized disc spring 14, and a composite busbar friction pair 1, and the composite curved friction pair 1 is a fixed cone The disk 12 is coaxial with the movable cone disk 13, the cone faces are opposite, and the two are connected by a flexible closed-loop friction contact formed by the friction plate 16. The fixed cone disk 12 is fixed on the input shaft 11, and rotates with the input shaft 11. The other side of the movable cone 13 that slides axially along the input shaft is sequentially fixed with a pressurized disc spring 14 and a pressure plate 15, wherein the cone curves of the fixed cone 12 and the movable cone 13 are two sections of a straight line a...

Abstract

A mechanical friction type stepless speed variator is composed of mechanical pressing and speed-regulating mechanism, pressing disk, pressing spring and the friction set with complex generating line.Said friction set consists of static conic disk and moving conic disk, which are coaxial and have opposite conic surfaces, which are in contact by flexible closed-loop friction formed by frictino disks or pins. Said conic surface comprises a straight-line segment and a curve segment. Said mechanical pressing and speed-regulating mechanism is composed of bidirectional three-position clutch, symmetric planetary gear train, gear nut and external gear.

Description

technical field [0001] The invention relates to continuously variable transmission technology, in particular to a mechanical friction continuously variable transmission device with intermediate flexible elements such as belts and chains. Background technique [0002] Continuously variable transmission is a mechanical transmission device with continuously adjustable transmission ratio. Because it can adapt to the requirements of changing working conditions or continuously changing speed during machine operation, it is not only widely used in light industrial sectors such as textiles, food, paper, rubber, etc., but also It is also used in various mechanical equipment such as working machine (machine tool), overweight transportation, petrochemical industry, etc., especially its successful application in automobile transmission in recent years. [0003] The basic composition of mechanical friction continuously variable transmission for automobiles includes oil pump, forward and ...
