Abstract
The utility model provides a freewheel clutch of rotary speed control power principal and subordinate switching -over is formed by two sets of roller type overrunning clutch combination, and the first freewheel clutch's of group interior ring support, outer ring support surmount the outer ring support of separation and reunion with second group respectively, interior ring support solidifies and is in the same place. Under the initial condition, two sets of roller type overrunning clutch's roller the spring action be in respectively with the contact of outer ring support inner wall, disjuncture. There are three kinds of states in clutch work: low -speed, intermediate speed, high speed. Main drive drives the follower rotation during low -speed under the effect of the first roller type overrunning clutch of group, follower speed risees to and exceedes main drive speed during the intermediate speed, and roller type overrunning clutch is in disjuncture, when high -speed, follower speed is far above main drive speed, the anti - switching -over of dragging former main drive, realization power of second group clutch work. Aspects such as electric vehicle, engine worm wheel turbocharging system can be applied to to this clutch, and motor drive improves the performance of car during through low -speed, and counter when high -speed to drag the motor electricity generation to realize energy -conserving, guarantees that mechanism's operation is within the speed that suits.
Description
Technical field
The utility model relates to a kind of free wheel device, can realize the function that transferring power direction changes with rotation speed change.
Background technique
On automobile, assembly mechanism runs has best rotating speed, usually as exhaust gas turbocharge.Rotating speed too high or too low by the structure of mechanism or performance very unfavorable.If can a kind of mechanism be developed, make similar assembly can when low speed extraneous input power, outwardly outputting power during high speed, then not only can improve operational efficiency and the working life of mechanism, effectively can also save the economic performance that energy improves automobile.
Free wheel device is the basic part occurred along with the development of electromechanical integrated product, and it is the vitals for transmission of power and separation function between prime mover and working machine or between machine intimate driving shaft and driven shaft.It utilizes the velocity variations of driving and driven part or the conversion of sense of rotation, has the device of clutch function voluntarily.Conventional is roller-type overrunning clutch, and be made up of inner ring, roller, outer ring, spring and ejector pin etc., general inner ring is driving link, and outer ring is driven member, and when inner ring rotates counterclockwise, roller is driven outer ring rotating by wedging, and clutch engages; When inner ring rotates clockwise, roller is retracted into sipes position, and outer ring is then motionless, clutch separation.Wedge type over running clutch and slide block type free wheel device because of voussoir and slide block more, bearing capacity is higher, and its working principle is similar to roller clutch.
What free wheel device had interrupt automatically with rotating speed or in conjunction with the feature of power, be widely used in mechanical transmission, become one of focus of mechanical transmission mechanism research.But the mechanism of power unidirectional delivery is all belonged at current free wheel device, above-mentioned function (can when low speed extraneous input power, outwardly outputting power during high speed) demand cannot be realized.
Summary of the invention
The problem of the mechanism of power unidirectional delivery is all belonged in order to solve current free wheel device, the utility model proposes the free wheel device that a kind of rotating speed controls power principal and subordinate commutation, rotating speed can be realized and control principal and subordinate's power commutation function, can when low speed extraneous input power, outwardly outputting power during high speed.
The utility model mentality of designing is: by two straight roller formula free wheel device combinations, utilize the relation of centrifugal force and rotating speed, the mechanism of design motivation back transfer, the function changed with rotating speed in conjunction with power under realizing rotary speed direction invariant state.That is: when low speed starts, driving mechanism rotating speed is higher than follower rotating speed, and free wheel device combination realizes power and is delivered to follower by driving mechanism; During middling speed, follower rotating speed is separated higher than driving mechanism free wheel device and realizes power interruption; When follower rotating speed is too high, free wheel device again combines and makes follower power reverse input driving mechanism.
The technical solution of the utility model is achieved in that
A kind of rotating speed controls the free wheel device of power principal and subordinate commutation, comprise left roller-type overrunning clutch, right roller-type overrunning clutch, it is characterized in that: the inside and outside ring support of left roller-type overrunning clutch is consolidated with outer, the interior ring support of the right free wheel device respectively; Under spring force, the roller of left roller-type overrunning clutch and outer ring support are in normal separated state; Roller and the outer ring support of right roller-type overrunning clutch are in normal bonding state; Left roller-type overrunning clutch spring one end is fixed on interior ring support by pin, and the left roller-type overrunning clutch spring the other end is hook-shapedly hooked in roller mid diameter smaller part by making.
Except above-mentioned essential features, the utility model, in specific implementation process, also can have following technical characteristics.
The interior ring support of left roller-type overrunning clutch and the as a whole part of outer ring support of right roller-type overrunning clutch, its Power output is another one end-cover axle, and end-cover axle in one-piece parts, realizes transmission of power on output terminal by bolt or rivet interlacement.This structure is convenient to manufacture and assembling.
The outer ring support of left roller-type overrunning clutch and the interior ring support of right roller-type overrunning clutch belong to two parts, are consolidated by spline and snap ring, and power is inputted by the splined shaft of the inner ring of right roller-type overrunning clutch.This structure is convenient to manufacture and assembling.
The structure be consolidated of the inside and outside ring support of left free wheel device, interior ring support outer with right free wheel device respectively, can be provided with multiple union piece, realize consolidation by welding or other Placement.This structure expressed can change.
The beneficial effects of the utility model: by the ingenious combination of two common overrun clutch structures, make the transmission of power direction of clutch can realize low speed automatically in conjunction with forward transferring power according to the change of driven rotating speed, during middling speed, clutch disconnects realization and surmounts and slide, during high speed, clutch combines automatically, reverse power transmission, contributes to the recovery of excess energy.This structure takes full advantage of the advantage of roller overrunning clutch, make the transmission of power forward, disconnection, back transfer process in conjunction with soft, be separated rapidly, vibratory impulse and noise low.The rotating speed that this structure medium power back transfer combines need higher than rotating speed during separation, and the rigidity that the rotating speed of its reverse power transmission binding site controls by changing spring realizes, and is convenient to producing in serial form.
