Description
Technical field
The utility model belongs to machine power and transmits the field.
Background technique
Mechanical facility will be realized the gear graduation of high and low shift at present, is generally the convenient engagement that solves high low speed gear, beat tooth, shock otherwise usually cause with the additional device of synchronizer and so on, will wait for Shift gear moment toward contact, causes power transmission to interrupt.Especially concerning being at present the manual automobile, electric motor car green hand driver of more than one hundred million in China, not only cause power interruption because of gear shift, have a strong impact on the speed of a motor vehicle and the road is clear, and because of the speed changer structure complexity, it is a particularly car load great system of electric motor car of automobile, cost will account for most of car load, has greatly improved car weight and car fare, affects traffic and electric motor car industry development.
Summary of the invention
For improving the speed of a motor vehicle, reduce car fare, promote automobile to come into more middle and low incomes family, realize the electric motor car industrialization, improve national oil selfsufficiency, reduce exhaust emission pollution, the utility model is intended to simplify mechanical variable speed device, particularly reduce deadweight and the cost of this high-speed motion machinery of (electronic) automobile, facilitate speed change, propose following technological scheme:
The utility model provides a kind of brand-new type automatic power transmission, belongs to machine power and transmits the field.On this speed changer diaxon, on an axle, the interval gap is fixed wtih two and above high low speed gear of different-diameter, the number of teeth.On the spline of another variable-speed shaft axially side by side separated type be equipped with the piece formula of the carving one-way element without interior ring of two and above remodeling, in each one-way element ring for holistic, Intermediate Gray is bossed, long the overlapping of slip ring that can laterally slide along spline, be the speed change sliding sleeve, hereinafter referred to as sliding sleeve; On each outer ring for one-way device that separates with two and above high low speed gear of different-diameter, the number of teeth.Slide over when endwisely slipping along spline and can require to stop in a certain position according to controlling, the projection on sliding sleeve can correspondingly contact a certain one-way element at this moment, and flat (or the saying recessed portion) on sliding sleeve be corresponding another one-way element.When this one-way element synchronous forward of splined shaft forward rotation, sliding sleeve and projection also forward rotation and the corresponding contact of drive is rotated, on outer ring for one-way device, the high low speed gear of fixing a certain gear also synchronously rotates, and the output gear of gear engagement also is with the high or low shelves running of movement machine therewith; At this moment, though the one-way element that the sliding sleeve flat of bottom is corresponding is forward rotation, but flat on the sliding sleeve that ring is corresponding with it in it does not contact asynchronous rotation, corresponding outer shroud cogs and certainly can't synchronously rotate, and this moment, this outer ring for one-way device or the gear that joins with it dallied with the gear on the output shaft that is engaged with under the support with the supporting element of ball or pulley that speed changer is separately established.Also can separately establish one on flat (or the saying recessed portion) on sliding sleeve can be along its axle sleeve that trackslips, loop contacts in flat (or saying recessed portion) on sliding sleeve whole laterally slip, sliding sleeve and the upper axle sleeve that trackslips along it and a certain one-way element, in one-way element, endless belt moves this axle sleeve and flat trackslipping, with whole sliding sleeve also asynchronous rotation.Splined shaft drives the sliding sleeve backward rotation to be separated with the outer ring for one-way device of all forward rotation, does not drive its rotation.When sliding sleeve and projection slid into neutral gear between one-way element, all one-way elements did not turn, and are the machine neutral gear.Slide under the effect of shift fork or draw ring drag-line and so slide, the one-way element that projection is corresponding and gear change, and machine is also just realized speed change.
When the need shift, at first instantaneous shutoff power is laterally twitched sliding sleeve, and the one-way element of sliding sleeve projection contact is changed, and certain shifting gear that is attached thereto is respective change also, has namely realized the high and low shift conversion.
Separately establish one or several one-way element on the sliding sleeve of splined shaft, its forward rotation direction of conversion is former umklapp transformation forward, splined shaft and sliding sleeve backward rotation will drive one or several one-way element forward rotation and reverse gear corresponding to its one-way element rotated, and namely realize reverse gear.
