Embodiment Construction

[0039] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0040] It should be noted that when a component is said to be "connected" to another component, it may be directly connected to the other component or intervening components may also exist. When a component is said to be "set on" another component, it may be set directly on the other component or there may be an intervening component at the same time.

[0041] Unless otherwise defined, all technical and scientific terms used herein have the same ...

Abstract

The invention provides a stepless speed change device which comprises an output shaft, an input shaft, a transmission part and a speed change driving mechanism. The output shaft comprises a conical cylinder which is hollow inside, the outer side surface of the conical cylinder is used for outputting driving force, and the inner side surface of the conical cylinder is a first acting surface. The input shaft comprises a conical solid body arranged inside the conical cylinder, the conical surface of the conical solid body is a second acting surface, the conical direction of the second acting surface is opposite to the conical direction of the first acting surface, and a first generatrix of the first acting surface is parallel to a second generatrix of the second acting surface. The speed change driving mechanism is used for driving the transmission part to move along a working path to change the transmission ratio between the input shaft and the output shaft, and the working path extendsin the direction of the first generatrix and the second generatrix. According to the technical scheme, the size is compact, so that layout and installation inside an engine room are convenient, meanwhile, the speed change effect is smooth, and the speed change effect is good.

Description

technical field [0001] The invention relates to the field of transmissions, in particular to a continuously variable transmission device. Background technique [0002] Continuously variable transmission is a key issue in the later stage of automobile development. In the era of pursuing automobile comfort, continuously variable transmission is popular for its stable acceleration and fuel-saving characteristics under acceleration. At present, there are hydraulic transmission, electric transmission and mechanical transmission in the way of continuously variable transmission, and mechanical transmission is more reliable. In the mechanical transmission that has been designed, if there is tooth structure meshing, it is an infinitely close to infinitely variable transmission, not a real infinitely variable torque. The mechanical transmission with infinite variable torque has disc type, conical type and spherical type. The conical type is divided into direct contact and indirect c...
