Embodiment Construction

[0021] In the figure, the square dashed box is a schematic diagram of a planetary row structure speed change device, and the circle dashed box is a schematic diagram of the differential. The double-cone ring continuously variable transmission device is composed of input and input cone 1, output shaft 2, ring 3, speed regulating device 4 and spring 6, etc. The main reducer is composed of the main reducer small tooth 20 and the main reducer large tooth 21 . There is a pair of reversing gears (gear 23 and gear 24 ) between the power input end and the input input cone 1 . When the power rotation direction of the power source changes, the pair of reversing gears can be cancelled.

[0022] figure 1 The embodiment shown is a double-planetary row parallel shaft with mutually inverted cone and double cone ring type continuously variable transmission. The axes of the input cone 1 and the output cone 2 are parallel to each other, and are installed upside down to each other, and the co...

Abstract

Provided is a double-cone ring type continuously variable transmission. A pair of parallel shafts mutually has cones inverted, a ring is internally tangent to the two cones at the same time and pressed tightly to the cones through pressing devices inside the cones, and power is transmitted through friction force between the ring and the cones. Through a speed regulation device, the ring is changes its position on the cones, so that changes of different speed ratios can be realized. Since changes in position of the ring on the cones are continuous, continuously variable transmission can change speed continuously. A planetary row structure speed change device provided with two forward gears and one reverse gear is in array configuration with the double-cone ring type continuously variable transmission. The double-cone ring type continuously variable transmission has the advantages that the continuously variable transmission is simple in structure, capable of continuously varying in speed and wide in transferrable torque range. The requirements on vehicle dynamic performance and economical efficiency can be met, and the requirements that the speed change device is small in size, light in weight and wide in speed change ratio coverage range can also be met.

Description

technical field [0001] The invention relates to a continuously variable transmission, which is especially suitable for a double cone ring type continuously variable transmission for vehicles. Background technique [0002] The United States Patent US1709346 describes a double-cone-ring continuously variable transmission device that uses parallel shafts to mutually invert the cones and uses the inter-cone rings to transmit power and speed. The cone and the inter-cone ring are clamped by mutually inverting the cone, and the torque is transmitted by the friction between the cone and the inter-cone ring. Later, in order to transmit larger torque and prolong the service life, a traction oil was added between the cone and the ring to increase the friction coefficient and reduce the wear between the cone and belt. The reality is that the transmitted torque is limited due to the fact that the ring is circumscribed by a cone. [0003] In order to realize the positive and negative ou...
