Embodiment 1

[0066] a transmission device such as figure 1 -3, it includes a driving cone 101, a first driving cone 102, a driven cone 103, a second driving cone 104 and a transmission mechanism 105.

[0067] Wherein the driving cone 101 rotates at a set input speed, the first driving cone 102 contacts and drives the driving cone 101, the second driving cone 104 contacts and drives the driven cone 103, and the first driving cone 102 passes through The transmission mechanism 105 is connected with the second transmission cone 104, wherein the axis of the first transmission cone 102 is perpendicular to the axis of the driving cone 101, and the axis of the second transmission cone 104 is perpendicular to the axis of the driven cone 103. between vertical, such as figure 1 shown;

[0068] Further, the axis of the driving cone 101 and the axis of the driven cone 103 are collinear (coaxial).

[0069] The transmission mechanism 105 in this embodiment can be a gear transmission group, also can be...

Embodiment 2

[0076] This embodiment provides a transmission, such as Figure 4 -9, including input shaft 201, output shaft 202, driving cone 203, more than two first driving cones 204, driven cone 205, more than two second driving cones 206 and more than two The transmission mechanism 207, wherein the first transmission cone wheel 204, the second transmission cone wheel 206 and the transmission mechanism 207 have the same number and one-to-one correspondence.

[0077] In this embodiment, for example, eight first transmission bevel wheels 204 and eight second transmission bevel wheels 206 are provided, wherein the eight first transmission bevel wheels 204 are arrayed around the axis of the driving cone 203, and the eight second transmission bevel wheels The cone wheel 206 is arrayed around the axial direction of the driven cone 205, based on the same principle as in Embodiment 1, combined with Figure 7 , 8 As shown, by adjusting the contact position between the first driving bevel 204 an...

Embodiment 3

[0093] This embodiment provides a transmission, such as Figure 10 As shown, the difference between this embodiment and Embodiment 2 is that the first screw rod is replaced by the first speed-regulating slider 301 with end thread in the transmission mechanism, so that the first speed-regulating slider 301 and the first An end thread pair is formed between the frames 302 , and the second screw mandrel is replaced with a second speed regulating slider 303 with end threads, and an end thread pair is formed between the second speed regulating slider 303 and the second frame 304 .

Abstract

The invention provides a stepless speed change device and a gearbox. The speed change device comprises a driving cone disc, at least one first transmission cone pulley which is in contact transmission with the driving cone disc, a driven cone disc, at least one second transmission cone pulley which is in contact transmission with the driven cone disc and a transmission mechanism. The first transmission cone pulley can move between the maximum circumference and the minimum circumference of the driving cone disc, the second transmission cone pulley can move between the maximum circumference and the minimum circumference of the driven cone disc, and the first transmission cone pulley is connected with the second transmission cone pulley through the transmission mechanism. The device has the advantages of large transmission torque, high reliability and low cost.

Description

technical field [0001] The invention belongs to the technical field of speed change, and in particular relates to a continuously variable speed change device and a gearbox. Background technique [0002] The gearboxes for fuel vehicles generally include MT (manual transmission), AMT (mechanical automatic transmission), AT (automatic transmission), CVT (continuously variable transmission), DCT (dual clutch transmission), of which CVT (continuously variable transmission) is outstanding The smoothness of shifting and fuel economy are used by more and more cars. [0003] Existing CVT continuously variable transmission devices mainly include four types of belt type (chain type) CVT, wheel type CVT, ring type CVT and ball type CVT. [0004] Belt (chain) CVT has a small contact area between the steel belt (or steel chain) and the transmission cone surface, which is easy to slip, and the steel belt (or steel chain) is extremely easy to wear and cause breakage in extreme conditions, ...
