Abstract
This utility model is related to Clutch Technology field, more particularly to a kind of fluid torque-converter roller clutch, including multiple rollers and outer ring, the cam path equal with roller quantity is evenly distributed on the inner peripheral surface of outer ring, roller is located in cam path, it is also equipped with, for roller to be pushed the spring leaf of the cell wall to cam path, on the outer circumference surface of outer ring, being equipped with tooth-shape structure in cam path.Fluid torque-converter roller clutch of the present utility model, using the densely covered profile of tooth of outer ring excircle, to carry out transmitting torque with guide wheel interference fit, contact area is big, bearing torque effect is good, the installation of screw parts is reduced, on the premise of use requirement is met, cost and assembly precision requirement is reduced.
Description
Technical field
This utility model is related to Clutch Technology field, more particularly to a kind of fluid torque-converter roller clutch.
Background technology
Fluid torque-converter roller clutch is installed in the guide wheel of fluid torque-converter, when pump impeller starts to rotate, first,
ATF oil flows to turbine and drives turbine rotation, and then, ATF oil flows out turbine and clashes into guide wheel and returns pump impeller realization supercharging.This mistake
Cheng Zhong, needs to ensure the static impulsive torque for bearing ATF oil of guide wheel.When pump impeller reaches certain rotating speed, due to the flow direction of ATF oil
Change, ATF oil is crossed guide wheel after flowing out turbine and returns pump impeller.During this, guide wheel and pump impeller, turbine is needed together to revolve
Turn.In order to allow guide wheel realize both the above function, one-way clutch is introduced.
The one-way clutch of early application is wedge block type clutch, although can carry high torque, but relatively actual
Operating mode, shows slightly more than needed, and high cost, assembly precision have high demands.And as scientific and technological progress develops, the machining accuracy of each part
It is substantially improved, so introducing the roller clutch that disclosure satisfy that use requirement.
Before existing Multi-roller overrunning clutch (CN201651113U) is used in, this is used in motorcycle engine
In, it is that clutch and magneto are connected, clutch is installed on connected piece by screw, the bearing torque effect of screw
It is not good.
Utility model content
The technical problems to be solved in the utility model is：For reduces cost and meet assembly precision requirement and same
Disclosure satisfy that use requirement.
This utility model solves the technical scheme adopted by its technical problem：A kind of roller clutch of fluid torque-converter
Device, including multiple rollers and outer ring, are evenly distributed in the cam path equal with roller quantity on the outer ring inner peripheral surface, described
Roller is located in cam path, is also equipped with for roller to be pushed the spring leaf of the cell wall to cam path in the cam path, described
Tooth-shape structure is equipped with the outer circumference surface of outer ring.In order to not produce relative motion with guide wheel during realizing transmitting torque, this
, using the densely covered profile of tooth of outer ring excircle, to carry out transmitting torque with guide wheel interference fit, contact area is big, traditional for utility model
The bearing torque of screw is not as good as tooth-shape structure.
Further, it is that raising uses durability degree, the cam path to adopt off-centre operation cambered surface, cam groove face and roller-contact
Wedging action is formed, so as to transmitting torque, is engaged with above-mentioned tooth-shape structure, can more with further bearing torque.
Further to improve torque capacity, the quantity of the roller is 6-12.
The beneficial effects of the utility model are, fluid torque-converter roller clutch of the present utility model, using outer ring
Excircle gathers profile of tooth, and to carry out transmitting torque with guide wheel interference fit, contact area is big, and bearing torque effect is good, reduces
The installation of screw parts, on the premise of use requirement is met, reduces cost and assembly precision requirement.
Description of the drawings
With reference to the accompanying drawings and examples this utility model is further illustrated.
Fig. 1 is the structural representation of new fluid torque-converter roller clutch.
In figure：1st, outer ring, 11, cam path, 12, profile of tooth, 2, spring leaf, 3, roller.
Specific embodiment
This utility model is described in further detail presently in connection with accompanying drawing.These accompanying drawings are simplified schematic diagram,
Basic structure of the present utility model is only illustrated in a schematic way, therefore which only shows the composition relevant with this utility model.
As shown in figure 1, be this utility model optimum embodiment, a kind of fluid torque-converter roller clutch, including it is many
Individual roller 3 and outer ring 1, are evenly distributed in the cam path 11 equal with 3 quantity of roller on 1 inner peripheral surface of outer ring, roller 3 is located at convex
In race 11, be also equipped with cam path 11 for roller 4 to push the spring leaf 2 of the cell wall to cam path 11, outer ring 1 it is cylindrical
Tooth-shape structure 12 is equipped with side face.The cam path 11 adopts off-centre operation cambered surface.The quantity of roller 3 is 9 and (but is not limited only to
9).
In order to realize not producing relative motion during transmitting torque with guide wheel, 1 excircle of outer ring gathers profile of tooth 12, to
Carry out transmitting torque with guide wheel interference fit, contact area is big, the bearing torque of traditional screw is not as good as tooth-shape structure.Plus described
Cam path 11 adopts off-centre operation cambered surface, and cam groove face contacts to form wedging action with roller 3, so as to transmitting torque, with above-mentioned tooth
Shape structure is engaged, can more with further bearing torque.
With it is above-mentioned according to desirable embodiment of the present utility model as enlightenment, by above-mentioned description, related work people
Member can carry out various change and modification completely in the range of without departing from this utility model technological thought.This reality
The content being not limited to new technical scope in description, it is necessary to its technology is determined according to right
Property scope.
