Abstract
The utility model belongs to a speed change mechanism, more specifically a planetary differential stepless speed change mechanism which is provided with at least two gear sets, wherein each gear set comprises a gear sleeve which is arranged on each shaft, and a sun gear and a planetary gear which are arranged in the gear sleeve, wherein the planetary gear is fixed on a speed regulating gear which is arranged on the same shaft by a bearing through a planetary frame, and the stepless speed change purpose is realized by the cooperation of the two sets of gears. The utility model is suitable for the speed change transmission of motor vehicles, such as various automobiles, tractors, etc. By utilizing the utility model, the vehicle speed can be controlled by controlling the rotation speed of a throttle engine, and the service life of the engine is extended; the power of the engine is fully used, and the speed reduction of the engine can not perform a braking function.
Description
The utility model belongs to speed-changing mechanism, specifically a kind of planet differential formula stepless speed changing mechanism.
At present, the speed-changing mechanism of power actuated vehicle is generally step change and stepless change two classes.Stepless change is owing to its simple to operate, easy grasp, so obtained being extensive use of in various vehicles.The stepless speed changing mechanism that uses has three classes at present, that is: mechanical stepless speed change-and mainly be basic principle, because of it is omnidistance greatly, how loss in efficiency is used for dilly substantially with the centnifugal force; Electric power stepless change-realize infinite speed variation by electrical generator, motor control electric energy because two machine weight are big, big energy-consuming, is mainly used in the not high vehicle of performance requriements; Hydraulic stepless speed change has from heavy and light, advantages of simple structure and simple, but its working accuracy height, loss in efficiency are big, the life-span is shorter relatively, are only limited on the special car.
The purpose of this utility model be to provide a kind of full mechanical drive, simple in structure, cost is low, easy processing, power consumption, can be according to the stepless auto gear of power rotating speed height, the direct differential of payload.
The utility model has at least two gear clusters, and each gear cluster comprises tooth cover and wherein sun gear and the planetary wheel that is installed in respectively separately on the axle, and planetary wheel is fixed on by bearing installation on coaxial governor gear by pinion carrier; Wherein the tooth in the upper class gear cluster puts and has external tooth, the governor gear engagement in it and the next stage gear cluster; The next stage gear cluster the axle on be fixed with the upper class gear cluster in governor gear ingear transmission gear.
The utility model comparatively is applicable to the speed change transmission of self-propelled vehiclees such as various automobiles, trac..Utilize the utility model to carry out infinite speed variation automatically, promptly just can control the speed of a motor vehicle, can alleviate the fatigue of chaufeur and parts so greatly by the rotating speed of control throttle driving engine according to the height and the floor loading size of engine speed.The utility model can be passed to undercarriage with the power of driving engine reposefully, again the load of undercarriage is passed to driving engine, like this, not only can prolong the life-span of driving engine undercarriage, has also made full use of the power of driving engine.It can also make full use of the inertia of vehicle, makes engine retard can not play brake action.
In the utility model, the axle of each gear cluster is installed on its axle by back-up ring and nut with the tooth cover.Perhaps the tooth in the afterbody gear cluster overlaps and its bearing fit, and output shaft is captiveed joint with the tooth cover; Axle in other gear cluster is installed on its axle by back-up ring and nut with the tooth cover.
According to the design needs, the governor gear number of teeth of next stage gear cluster is more than the number of teeth of tooth cover external tooth in the upper class gear cluster middle gear, is less than the number of teeth of governor gear in the upper class gear cluster with the number of teeth of the axle bonded assembly transmission gear of next stage gear cluster.
Generally speaking, when concrete the use, adopt two gear clusters.
Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated.
Fig. 1 is the cutaway view of the utility model embodiment;
Wherein, 1-governor gear, 2-pinion carrier, 3-nut, the 4-bearing, 5-axle, 6-pinion carrier, 7-nut, the 8-planetary wheel, 9-tooth cover, 10-sun gear, 11-jackscrew, the 12-nut, 13-keypad, 14, the 15-nut, 16-planetary wheel, the 17-governor gear, 18-pinion carrier, 19-nut, 20-tooth cover, 21-planetary wheel, 22-nut, the 23-output shaft, 24-nut, 25-planetary wheel, the 26-pinion carrier, 27-jackscrew, 28-sun gear, the 29-nut, 30-bearing, 31-transmission gear, the 32-key, 33-nut, 34-axle.
As shown in the figure, present embodiment is made up of the two-stage gear cluster, every grade of gear cluster comprise a tooth cover 9 or 20 and be installed on one of them sun gear 10 or 28, four planets 8,16 or 21,25 gears with and governor gear 1 or 17 in the outside.Four planetary pinion carriers 2,6 or 18,26 are installed on its governor gear, each sun gear 10 or 28 and its axle 5 or 34 be fixedly connected.Each governor gear 1 or 17 connects with its axle by bearing 4 or 30.Tooth cover 9 has internal tooth and external tooth in first order gear cluster, and it is connected by nut with its axle 5, and meshes with governor gear 17 in the gear cluster of the second stage, and wherein, the diameter of this governor gear 17 overlaps 9 external diameter greater than tooth.20 in tooth cover in the gear cluster of the second stage has internal tooth, and its end is connected with output shaft 23 by screw, and the axle 34 of this gear cluster is arranged in the endoporus of tooth cover 20, with its running-fit.The axle of second stage gear cluster also is fixed with a less transmission gear 31 on 34, it with first order gear cluster in bigger governor gear 1 mesh.
