No matter the present invention is the lock ring of Split type structure or integrally-built lock ring all has lock banking stop, adopt elastic sheet metal impact briquetting, the lock ring of Split type structure adopts the stamping forming monomer-type lock banking stop of monolithic, elastic metallic material is adopted to strike out the similar shapes that can produce elastic force such as the shape of similar " second " word or C font, V-shaped, the lock banking stop lower end fixing part of all monomer-type lock banking stops is fixed on the outer ring of a shaft-like power transmission member, lock banking stop upper end friction part on it is arranged in the same direction, forms the lock ring of ring-type; Integrally-built lock ring, from annular matrix, directly stamp out unidirectional lock banking stop upper end friction part towards direction, outer ring, wherein lock banking stop lower end fixing part is then the annular matrix of lock ring.All lock banking stop upper ends friction part of lock ring contacts with the inner ring face of another power transmission member after extrusion-deformation, by lock ring from a power transmission member transferring power to the process of another power transmission member, when lock banking stop upper end friction part is subject to two rightabout tangential friction forces respectively, the distortion of the lock banking stop of lock ring is different, the tangential friction force in one of them direction makes the lock banking stop upper end friction part of lock ring raise up, the tangential friction force in another direction can make the lock banking stop upper end friction part of lock ring decline, and the elastically-deformable change of lock banking stop upper end friction part height and lock banking stop makes the positive pressure of lock ring to the inner ring face of axle also change, the maximum static friction force that such two different direction can bear is different, two coaxial axial workpiece transmitting torques are being transmitted by lock ring, just can realize, the transmission of power of anti-both direction, wherein active power transferring elements is when sense of rotation is different, the Maximum Torque that can transmit is also different.
Such as, this lock ring is connected in the outer surface of a driving shaft (active power transferring elements), be uniformly distributed a circle, the coaxial hollow driven shaft sleeve (driven power transmission member) of another root is on lock ring on the friction part of equally distributed lock banking stop upper end, the inner ring of driven shaft sleeve compresses lock banking stop upper end friction part, makes lock banking stop upper end friction part produce resiliently deformable.When driving shaft rotates, the lock banking stop upper end friction part being connected in the lock ring of driving shaft periphery produces frictional force thus drives driven shaft sleeve to rotate under elastically-deformable effect.And the deformation tendency that above-mentioned tangential friction force can force lock banking stop upper end friction part to produce further to raise up change the positive pressure of lock ring and driven shaft sleeve inner ring, different torque direction can make the deformation form of the lock banking stop upper end friction part of lock ring different, and then the maximum static friction force both changing, or in other words, change the Maximum Torque that driving shaft can transmit.
The present invention is on the basis of lock ring, also can add a braking hoop on the upper end friction part of lock ring, by shrinking brake hoop, initiatively the upper end friction part of lock ring is all shunk, lock banking stop upper end friction part is separated with the inner ring face of power transmission member, realize power cut, realize the function of clutch.
For ensureing in clutch work, the lock banking stop of lock ring is forced under brake hoop effect that pressure distortion is excessive causes plastic deformation, cause the damage of lock ring, at the primary deformable parts of lock ring---the below of-lock banking stop upper end friction part arranges lock banking stop end support portion, for supporting the largest deformation amount limiting elasticity upper end friction part, ensure the normal work of lock ring.According to the difference of lock ring structure, the lock banking stop end support portion of monomer-type lock banking stop directly adopts the bending structure with lock banking stop lower end fixing part one, arranges with the upper end friction part head and the tail of adjacent monomer formula lock banking stop, and finally circlewise; Integrally-built lock ring, then by the punching of lock banking stop upper end friction part, the outer ring of power transmitting elements arranges corresponding support protrusion portion as lock banking stop end support portion, also can realize lock ring simultaneously and be sleeved on locating function on power transmitting elements.
Above-mentioned clutch can be applicable in all kinds of speed changer, as on the two-shift automatic variable speed device of new-energy automobile, connect gear ring and the planet carrier of epicyclic transmission, when the brake hoop compact lock stop ring of planet two-shift automatic variable speed device, make the lock banking stop of lock ring produce resiliently deformable, thus separate with speed changer planet carrier inner ring; When the brake hoop of planet two-shift automatic variable speed device unclamps lock ring, lock ring resiles under the effect of its own resilient, thus compresses with speed changer planet carrier inner ring, and the direction of the two friction will make to form friction self-locking each other, is formed and reliably connects.
In conjunction with the structure of lock ring, the gear ring outer ring of suit lock ring arranges corresponding mounting structure, the monomer-type lock banking stop of corresponding Split type structure, the outer ring of gear ring is arranged to the plane of the lock banking stop lower end fixing part of several corresponding monomer-type lock banking stops, the lock banking stop lower end fixing part of monomer-type lock banking stop is pasted and fixed in plane one to one, forms lock ring; Corresponding integrally-built lock ring, arranges the support rim of punching on several corresponding lock rings, forms the lock banking stop end support portion of described lock ring in the outer ring of gear ring.
Compared with prior art, the invention has the advantages that:
Described lock ring can along both direction being transmitted the moment of torsion varied in size, based on the clutch of this lock ring and two gear planetary automatic transmissions of application, instead of existing complicated operation, clutch with high costs, there is the advantage that structure is simple, volume is little, quality is light, cost is low, and the gearshift of automatic transmission responds soon, it is little, easy and simple to handle to impact, in mechanical transmission fields, particularly growing at present new-energy automobile extensively can be promoted.
