Description

TECHNICAL FIELD The invention relates to the field of mechanical continuously variable transmissions, and in particular to a long tapered roller cone type continuously variable transmission mechanism. BACKGROUND OF THE INVENTION A mechanical continuously variable transmission has many advantages such as simple structure, high reliability, convenient stepless speed regulation, and the like, and has many cone-shaped wheels, planetary cone wheels, belts, chains, and the like. Pulsating and so on. In recent years, the mechanical long roller cone type shifting transmission mechanism has received extensive attention and research, but there are few major innovations and breakthroughs in the structure.

With the variable-speed main transmission, the driven pulley and the metal belt to realize the stepless change of the speed ratio, the transmission effect is high, the shift range is wide, and the stepless speed change can be realized in a relatively wide range. Therefore, the transmission system and the engine operating conditions are matched to improve the fuel economy of the vehicle. In the last ten years, the CVT (Cont i nuous ly Varia ble Trans-mi ssion) stepless transmission technology has been obtained. Very popular, it is widely used in the field of small power vehicles, but it is limited by metal strip materials and technology, making the manufacturing cost very high.

The cone-wheel type continuously variable transmission mainly relies on the contact friction of the main and driven rigid components (or through the intermediate components) and the traction of the oil film to transmit _Z- ,], and can be continuously changed by changing the working radius of the contact portion. The utility model has the advantages of stable transmission, small noise, simple structure, overload protection effect, various forms, etc. ii rW WU has more cone-ring disc type, multi-disc type, steel ball cone wheel type, rhomboid type, planetary cone plate Type and row V. ring-cone type continuously variable transmission; etc.; in the cone-wheel friction type continuously variable transmission, the cone wheel and the contacted transmission element are subjected to load friction work, which is due to the geometry of the cone wheel and the contacted transmission element The speed distribution of the two rolling elements is different, so that geometric sliding between the two rolling bodies occurs, and the geometric sliding in the mechanism causes the temperature of the pumping to rise and the traction coefficient to decrease, thereby causing the transmission force and efficiency of the transmission to be reduced, etc. Accelerate the wear of 'diiii' resulting in reduced life.

J! Wi technology 屮, in order to reduce the spin phenomenon of the friction drive contact zone in the cone-wheel type continuously variable transmission, many H gates will minimize the contact between the cone wheel and the contacted transmission component according to the magnitude of the transmission power. To reduce the geometric slip rate; to reduce the geometric slip rate in the cone-wheel friction type continuously variable transmission Small, only when the contact area between the cone wheel and the contacted transmission element is point contact, theoretically it is not produced: geometric sliding, the transmission efficiency is also the highest at this time; however, the cone wheel and the contacted transmission The smaller the contact between components, the worse the carrying capacity and the lower the transmission power. There is a contradiction between the two. For example, M solves the above technical problems, and there is currently no ideal solution in this field. .

As described above, the present invention proposes a novel structure of a mechanical continuously variable transmission, which can reduce the geometric sliding motion in the bevel gear transmission mechanism while increasing the contact area between the transmission elements of the cone wheel and the cymbal contact; For example, the maximum geometry in the range of 1 to 0. 4~2. 5 is the maximum geometry of the ratio of the gear ratio of the ratio of the gear ratio to the range of 1 to 0. Sliding < 0. 04 _; this 3⁄4; Ming 1; the geometric sliding in the entire adjustable gear ratio range is very small, almost negligible, can effectively improve the quality of the product ¹ :; performance, so that it can better adapt to various transmissions Mechanical working conditions require that the same type of cone wheel j: ^ class transmission is not possible.
