Abstract

A universal toothed chain type stepless speed change transmission device is mainly composed of a left cone disc, a right cone disc and a transmission disc. The universal toothed chain type stepless speed change transmission device is technically characterized in that according to an existing toothed chain type stepless speed changer, radial concave teeth and radial convex teeth on a left cone disc and a right cone disc of a driving wheel and a driven wheel are changed into radial peak valley-shaped teeth; a chain pin is changed to move inside a chain pin sleeve in the axial direction; the two ends of the chain pin are designed to be two-faced inclined conical teeth in the front-back direction; during transmission, the inclined conical teeth at one end are subjected to axial thrust between the peak valley-shaped teeth of the left cone disc or the right cone disc, and the chain pin moves in the axial direction, so that the two-faced inclined conical teeth at the other end of the chain pin are inserted into the valley-shaped portions of the opposite conical disc, and a peak-insertion valley-pin mode is formed. According to the universal toothed chain type stepless speed change transmission device, pure-inclined teeth mesh transmission is achieved, the noise is low, pulsation and slipping are avoided, and the speed ratio torque is quite large.

Description

Omnipotent toothed chain stepless speed change transmission device

Art

The present invention and a kind of toothed chain stepless speed change transmission device, especially a kind of omnipotent toothed chain engagement, non-slip, pulsating movement free, the very large infinitely variable speed transmission of speed ratio torque.

Background technique

At present, known CVT and pendulum pin chain are all frictional variable speed, and easily skidding to adapt to large torque.Some radiation concave-convex shape teeth in toothed chain stepless speed change active, follower left and right conical dish, be meshed with chain both sides slide plate transmission, its shortcoming is: on chain slide plate be tooth also non-be tooth, be rub and be not pure friction driving, form friction and engagement all can not accurately put in place, cause rotating speed low, speed ratio torque is little, only be applied in the slow-speed of revolution, in the machinery equipment that torque is little, and various large, medium and small automobile variable speed all do not apply toothed chain stepless speed change.

Summary of the invention

In order to solve existing toothed chain stepless speed change, speed ratio torque is very limited, can not enter automobile variable speed field.The invention provides a kind of omnipotent toothed chain, chat pure engagement type infinitely variable speed transmission, speed ratio torque is very large, can adapt to needed for the infinite variable speed motor vehicle of all needs such as various large, medium and small degree type automobile, tractor, tank and machine.

The technical solution adopted for the present invention to solve the technical problems is: existing toothed-chain type driven wheel, some radiation concave-convex shape teeth on left and right conical dish, change into some radiation peak valley shape teeth, peak and valley cube folder angular dimension is identical, peak and valley complement each other, left cone dish superiors and right cone dish upper valley axisymmetrical.Slide plate in the chain of existing toothed-chain type is removed, changes chain pin two ends into and be respectively two sides oblique cone tooth.Key (singly-bound or spline) is added in the middle of chain pin and sleeve pipe, pin can only be moved axially in sleeve pipe, pin two sides, one end oblique cone tooth makes the pin the other end insert dieback in symmetrical paddy by the thrust of cone dish superiors, insert paddy pin rodent for peak to close, during rotation, each chain pin one end is engaged the other end with the left side, peak and is engaged with on the right of peak, more specifically, each chain pin only has while be radial initiatively thrust, another side is radial, namely without thrust, also without pulling force, only have axial top power along with turn.With left and right conical dish peak valley tooth contact while of being multiple chain pin during rotation, the left side at peak had, the right at peak had, self-assembling formation pin and pin restrict mutually, chain pin at peak to any tooth position of the oblique parallel space of paddy, move axially dieback and stop, realize the engagement of omnipotent toothed chain.Equidistant chain link on chain is changed into non-equidistant chain link, in order to not allow two sides, equidistant pintle two ends oblique cone tooth, run into identical equidistant radiation peak valley shape tooth, forming chain pin one end is front surface of contact entirely, the other end is that rear surface of contact engages with cone dish peak valley shape tooth entirely, causes chain both sides stressed irregular.In the middle of active follower, install a servo-actuated groove gear, with chain syn-chro-step engagement rotation, controlling chain entirety can not axial runout.In order to make this stepless change, speed ratio torque can be infinitely great, and multiaxis can be adopted to connect, as three axle stepless change, be input as an axle, output is two axles, and jack shaft is three axles.

Beneficial effect of the present invention is, pulsating movement free, non-slip, achieve the very large stepless change of speed ratio torque easily, on left and right conical dish, only adopt radiation peak valley shape tooth, left and right conical dish peak and valley axisymmetrical, chain pin two ends are tooth, chain pin, move axially in sleeve pipe and engage with peak valley tooth, structure is simple, and cost is low, transmission efficiency is high, can adapt to needed for the various motor vehicle such as various degree type automobile, tractor and various machine stepless change.

Accompanying drawing explanation

First illustrate: because initiatively driven left and right conical dish is identical, the cross-sectional view only drawn a driving wheel and chain pin oblique cone tooth in FIG, being meshed, Fig. 2,3,4 drawn a left cone dish three-view diagram.

Below in conjunction with drawings and Examples, the present invention is further described.

1 driving shaft in figure, surface of contact before 2, the left cone dish of 3 driving wheel, 4 chain pins, 5 short chains, 6 keys, 7 sleeve pipes, surface of contact after 8,9 right cone dishes, 10 peaks, 11 long-chain joints, 12 paddy, chain link in 13,14 output shafts, the left cone dish of 15 output shaft follower, 16 jack shafts,, the left cone dish of 17 jack shaft follower, the left cone dish of 18 jack shaft driving wheel

Embodiment

Chain pin (4) front surface of contact (2) engages with left cone dish (3) peak (10) in FIG, that peak (10) radial push chain pin (4) front surface of contact (2) rotates, surface of contact (8) contacts with peak (10) the other end chain pin (4) is afterwards axial top power, does not namely have radial thrust also not have radial pull.Chain pin (4) two ends oblique cone tooth only has while be radial thrust, and another side does not have radial thrust and pulling force, only has axial top power to be servo-actuated.With reference to Fig. 5 each chain pin (4) two ends oblique cone tooth totally four surface of contact, when after contacting (2) two before two, surface of contact (8) contacts with left and right conical dish, only have surface of contact (8) and left and right conical dish peak valley tooth contact after a front surface of contact (2) and one, after two front surface of contact (2) or two appear in neither one chain pin (4) simultaneously, surface of contact (8) contacts with left and right conical dish, because left and right conical disk axis be not peak to peak valley to paddy, but peak forms space reasons to paddy.Sleeve pipe (7) is had outside chain lock (4), have key (6) (singly-bound or spline) between chain pin (4) and sleeve pipe (7), chain pin (4) can only move axially in sleeve pipe (7).Chain pin (4) moves axially and engages with peak valley shape tooth is soft contact, chain pin (4) oblique cone tooth move only extremely put in place with peak valley tooth top, " for extremely to engage; chain is separated into wheel and is easily separated; because the two sides oblique cone toothholder angle at chain pin two ends is identical with peak valley toothholder angular dimension, do not clamp resistance.
