Compared with the prior art, the service life of the spring of the overrunning clutch without a retainer is prolonged, a more reliable spring positioning device is provided, the processing mode of the left baffle plate and the right baffle plate is simplified, the reliability of the product is improved, and the production cost is also reduced.
Description
Technical field
The present invention relates to technical field of engineering machinery, particularly relates to a kind of free wheel device be applied in loader twin-turbine torque converter.
Background technique
At present, the loader of domestic 80% all adopts twin-turbine torque converter, twin-turbine torque converter and free wheel device co-operation, to gearbox input power, automatically can realize the switching between high speed light loading and low-speed heave-load, increase work efficiency, reduce driver's labor intensity.
Existing without retainer free wheel device by output gear 1, right baffle-plate 2, cam ring 3, roller 4, right baffle plate 5, the part compositions such as outer ring gear 6 and folded spring 7, as shown in Figure 1, it creatively eliminates retainer structure, ensure that when working between multiple roller separate, they are no longer by the constraint of traditional retainer, greatly eliminate the impact of machining error on discontinuity in roller work, these rollers participate in the carrying work of free wheel device fully under the effect of respective folded spring, improve reliability and the durability of free wheel device, but this structure has the following disadvantages:
1, existing folded spring 7 as shown in Figure 2, the thickness of spring sheet is about 0.1 ~ 0.25mm, and when free wheel device works in high speed light loading operating mode, roller High Rotation Speed producing with folded spring 7 rubs, because folded spring thickness is too thin, be easy to worn out by roller and lost efficacy.
2, existing right baffle-plate 2, right baffle plate 5 process boss retaining spring as shown in Figure 3, produce with outer-race ball track face to prevent spring from getting rid of outward under centrifugal action and rub scratch outer ring gear raceway and cause self wear out failure, but there is following problem in the boss 5-1 of the boss 2-1 of right baffle-plate 2, right baffle plate 5 processing: one is that boss is short, little with the area that spring is contacting, spring is easily being thrown out of boss space by under centrifugal action, therefore radial location reliability is low; Two are boss processed complex and need to remove lot of materials, and not only caused waste, manufacturing efficiency but also low, cost of production is high.
Summary of the invention
Object of the present invention is just to provide and a kind of changes the structure of existing spring and the orientation type of spring existing without on retainer structure free wheel device basis, and it can improve the working life of spring and reduce the free wheel device of cost of production.
Solution of the present invention is such:
The present invention includes outer ring gear, be positioned at the cam of outer ring gear, be fixedly mounted on the right baffle-plate of the cam ring left and right sides and right baffle plate, several rollers and the spring equal with its quantity, the wedge slot that described cam circle circumferential direction processing is equal with roller quantity; Described right baffle-plate and the pairing of right baffle plate have the through hole equal with roller quantity, and have breach on the through hole of right baffle-plate, and the through hole of right baffle plate has breach; Described both ends of the spring has positioning boss, and spring left end positioning boss is arranged in the through hole of right baffle-plate, right-hand member positioning boss is arranged in the through hole of right baffle plate.
The radial confined planes of the waist shaped hole of described right baffle-plate long arc shape connects with the radial limit convex table top of spring, and the radial confined planes of the waist shaped hole of right baffle plate long arc shape connects with the radial limit convex table top of spring, the radial motion of restraining spring.
Further: the interior edge face of described right baffle-plate connects with spring retainer boss face, the interior edge face of right baffle plate connects with spring retainer boss face, the axial motion of restraining spring.
Further: the front-end face of described spring connects with the cylndrical surface of roller, the ear end face of spring connects with the sphenoid surface of cam, the circumferential movement of restraining spring.
Further: the sectional shape of described spring is trapezoidal or U-shaped or J-shaped one.
Advantage of the present invention is:
1, the advantage without retainer free wheel device has been continued: the problem fundamentally solving the free wheel device failure of removal caused because of retainer fracture, substantially increases reliability and the durability of free wheel device, solve a long-standing problem client's difficult problem;
2, add the thickness of spring sheet, improve its wear resistance, improve the working life of spring;
3, change the orientation type of spring, spring is located more reliable;
4, simplify left baffle processing mode, while enhancing productivity, also reduce cost of production.
