Abstract

The invention relates to a belt transmission type continuously variable transmission mechanism, which belongs to the continuously variable transmission. In the technical scheme, the conical surface of the conical plate of an input/output belt pulley is provided with a plurality of curved surfaces which uniformly divide the conical surface of the conical plate along the circumstantial direction and form a wave type concave and convex shape, each concave curved surface or convex curved surface gradually shrinks along the radial direction to form an inverted triangle, and a mobile conical plate corresponds to the concave curved surfaces and the convex curved surfaces of a corresponding fixed conical plate; and a push type transmission belt is adopted to self-adaptively achieve the wave-shaped tight engagement along with the conical surface of the conical plate, thereby realizing the continuously variable transmission. The push type transmission belt and the conical plate of the belt pulley can not only transmit kinetic energy through friction, but also can increase the movement resistance so as to transmit the kinetic energy. Therefore, the invention reduces the component loss in friction transmission, and makes the power transmission more reliable.

Description

technical field [0001] The invention relates to a belt-driven continuously variable transmission mechanism in a continuously variable transmission. Background technique [0002] The belt-driven continuously variable transmission has been commercially applied in the automobile industry, and it is one of the most active fields in the research of automobile transmissions in recent years. Due to the continuous improvement of technology and the gradual improvement of performance, belt-driven continuously variable transmissions for vehicles are being widely used in low-power vehicles, and present a rapidly increasing development trend. The commercial application of V-shaped steel belt continuously variable transmission in automobiles has broad prospects. The disclosed commercial V-shaped steel belt continuously variable transmission mechanism consists of a driving steel belt pulley, a driven steel belt pulley and a V-shaped steel belt. Both the driving and driven steel pulleys a...
