Abstract
The utility model relates to a one-way overrunning clutch, in particular to a one-way overrunning clutch for a hydraulic torque converter. The one-way overrunning clutch comprises an inner ring, an outer ring, a wedge and a cushion spring, wherein the cushion spring is arranged between the inner ring and the outer ring and fixes the wedge between the inner ring and the outer ring, and the external diameter of the outer ring takes the shape of an ellipse. The structure of the one-way overrunning clutch effectively improves performance and effectively prevents skidding phenomenon, and reduces the output torque of an engine, the service life of the one-way overrunning clutch is the same as that of the vehicle engine, and the outer ring and the inner ring adopt punching processing, thus having lower cost, facilitating mass production, and improving work efficiency.
Description
Technical field
The utility model relates to mono-directional overrun clutch, relates in particular to a kind of fluid torque converter mono-directional overrun clutch.
Background technique
In the prior art, fluid torque converter generally all is to adopt roller type, roller-type overrunning clutch is made up of periphery, roller, spring and inner ring, this structure is incident to be the Surface fatigue wearing and tearing, typical failure mode is that spot corrosion is peeled off, occur skidding when working simultaneously easily, reduce engine output torque.Because during overrunning clutch work, roller is subjected to the effect of rotary centrifugal force all the time, thereby always attempts outwards to be offset from the point of contact with the periphery.Prior art constructions adopts roller type clutch, inefficiency and manufacture cost height.
The model utility content
The technical problems to be solved in the utility model is: the overrunning clutch unstable properties of original technology, stuck phenomenon appears easily, influence the transmission of Engine torque, reduce the deficiency of road holding, a kind of fluid torque converter mono-directional overrun clutch is provided.
In order to overcome the defective that exists in the background technique, the technological scheme that its technical problem that solves the utility model adopts is: the utility model comprises interior ring, outer shroud, voussoir and lining spring, be provided with the lining spring between interior ring and the outer shroud, the lining spring is fixed in voussoir between interior ring and the outer shroud.
According to another embodiment of the present utility model, comprise that further described outer shroud external diameter is an ellipticity.
The beneficial effects of the utility model are: structure of the present utility model effectively raises performance, effectively prevented skidding, this structure has improved engine output torque, working life can with the same life-span of vehicle motor, interior ring and outer shroud adopt punch process, cost is lower, is convenient to produce in enormous quantities, has improved working efficiency.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a side view of the present utility model;
Wherein: 1, outer shroud, 2, interior ring, 3, voussoir, 4, the lining spring.
Embodiment
With preferred embodiment the utility model is described in further detail in conjunction with the accompanying drawings now.These accompanying drawings are the schematic representation of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
Fig. 1 is a structural representation of the present utility model, and ring 2, outer shroud 1, voussoir 3 and lining spring 4 in comprising between ring 2 and the outer shroud 1, is characterized in that in lining spring 4 is fixed on: in lining spring 4 is fixed in voussoir 3 on ring 2 and the outer shroud 1.
When the outer shroud in the diagram rotated in the counterclockwise direction with respect to interior ring, voussoir was pushed run-off the straight, abdicates certain space between inner and outer rings, thereby can locking.Yet when if outer shroud is attempted to rotate along clockwise direction with respect to interior ring, voussoir is because of the cause of geometrical shape, and will be stuck in can't be movable between the inner and outer rings, thereby both are together locked.In other words, in case voussoir blocks inner and outer rings, then locking appears in overrunning clutch, and outer shroud can't be rotated in the direction of the clock with respect to interior ring, or interior ring rotates by counter clockwise direction with respect to outer shroud.The lining spring guarantee voussoir reliably wedge between inner and outer rings, make voussoir by the direction that can pin two rings, remain a bit, the elastic force effect of lining spring languid promotes voussoir and contacts with the inside and outside cover that mono-directional overrun clutch cooperates all the time, guarantees reliable one-way clutch performance.
With above-mentioned foundation desirable embodiment of the present utility model is enlightenment, and by above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this model utility technological thought.The technical scope of this model utility is not limited to the content on the specification, must determine its technical scope according to the claim scope.
Claims (2)
1. fluid torque converter mono-directional overrun clutch, comprise interior ring (2), outer shroud (1), voussoir (3) and lining spring (4), be provided with lining spring (4) between interior ring (2) and the outer shroud (1), it is characterized in that: lining spring (4) is fixed in voussoir (3) between interior ring (2) and the outer shroud (1).
