Abstract
The invention innovatively relates to a friction cone pair of an automobile synchronizer. A cavity is formed in a cone ring, a cone body is provided with a shoulder matched with the cavity, cone torque is generated between the cavity and the shoulder, two or three sets of friction cone pairs are formed accordingly, and namely the two or three sets of friction cone pairs can be formed just by the two parts; in this way, the cone torque is increased on the premise that other parts are not added, the synchronizer is simple in structure and arrangement, the axial length of a gearbox is not changed, and overall design is facilitated. Because a blind hole is formed in the inner surface of the shoulder and a first elastic element is arranged in the blind hole, coaxiality of the cone ring and the cone body is guaranteed, and vibration of the cone ring or the cone body is avoided.
Description
Technical field
The cone of friction that the invention relates in automobile synchronizer is secondary.
Background technique
At present, synchronizer is used widely in automotive industry, and what all on synchronous mode speed changer, adopt is inertia synchronizer, mainly combined cover, synchronous lock ring etc., consists of, and is characterized in relying on rubbing action to realize synchronous.
Conical surface Calculating Torque during Rotary in synchronizer is as follows:
Tc=F*μ*Rc/sina
Wherein, Tc-conical surface moment of torsion; F-berth-changing strength; A-friction pair face angle; Friction factor between μ-conical surface; The mean radius of Rc-cone of friction.
For obtaining larger conical surface moment, in the prior art, the normal radius that increases cone of friction, be specially the quantity that increases cone of friction, the mean radius of cone of friction is increased, this kind of mode is more common in bipyramid or multi-cone synchronizer, but it increases the amount of parts of synchronizer, structural configuration is complicated, and speed changer axial length is increased, and is unfavorable for its global design.
Therefore, need a kind of component that do not increase badly, can increase secondary appearance of cone of friction in the automobile synchronizer of conical surface moment.
Innovation and creation content
The problem that the invention will solve is to provide does not increase component, and the cone of friction that can increase in the automobile synchronizer of conical surface moment is secondary.
For solving the problems of the technologies described above, the technological scheme that the invention adopts is:
Cone of friction in a kind of automobile synchronizer is secondary, comprises conical ring 1, with the suitable cone 2 of conical ring, it is characterized in that, this conical ring is provided with cavity, and this cone is provided with the convex shoulder suitable with this cavity, between the internal surface of this cavity and the outer surface of this convex shoulder, produces conical surface moment.
As the restriction of the invention, this cavity circumferentially arranges along conical ring, and integral body is W shape.
As the further restriction of the invention, this convex shoulder circumferentially arranges along cone, and integral body is class M shape.
As the further restriction of the invention, this cavity is two, and this convex shoulder is two.
As further limiting again of the invention, this convex shoulder internal surface is provided with blind hole, in this blind hole, is provided with elastic element.
As further limiting again of the invention, between this conical ring and cone, form oil leab.
In the invention, conical ring is provided with cavity, cone is provided with the convex shoulder suitable with cavity, produces conical surface moment between cavity and convex shoulder, forms each other two groups or three groups of cones of friction pairs, only have two component just to form two groups or three groups of cones of friction pairs, and then do not increasing under the prerequisite of component, increased conical surface moment, make synchronizer structure, arrange simple, speed changer axial length does not increase constant yet, is beneficial to its global design.Because this convex shoulder internal surface is provided with blind hole, in this blind hole, be provided with the first elastic element, guarantee the concentricity of conical ring and cone, and then avoided the generation of conical ring or cone vibrations phenomenon.
Accompanying drawing explanation
Fig. 1 is the invention embodiment 1 structural representation.
Fig. 2 is the invention embodiment 2 structural representations.
In figure:
1, conical ring; 11,12, cavity; 2, cone; 21,22, convex shoulder; 23, blind hole; 3, elastic element.
Embodiment
Referring to Fig. 1, in the present embodiment, comprise conical ring 1, with the suitable cone 2 of conical ring, on this conical ring 1, along it, be circumferentially with cavity 11, in this cone 2, along it, be circumferentially with the convex shoulder suitable with this cavity 21, between the internal surface of this cavity and the outer surface of this convex shoulder, produce conical surface moment, between the outer surface both sides end face of the internal surface both sides end face of cavity and convex shoulder, form two groups of cones of friction secondary.
In order to guarantee the concentricity of conical ring 1 and cone 2, these convex shoulder 21 internal surfaces are provided with blind hole 23, are provided with elastic element 3 in this blind hole.
In addition, the conical surface of this conical ring 1 adopts helix structure, and forms oil leab between the oilhole of cone 2.
Referring to Fig. 2, the conical ring 1 in embodiment 2 is provided with cavity 12 in addition, and integral body is W shape; In cone 2, be provided with in addition the convex shoulder 21 suitable with cavity 12, integral body is M shape.
Cavity 12 internal surfaces form one group of cone of friction between the end face near convex shoulder 11 near the end face of cavity 11 and the outer surface of convex shoulder 21 secondary.Between two component, form three groups of cones of friction secondary, to a certain extent, the mean radius of cone of friction is increased, and then increase conical surface moment.
Other are with embodiment 1.
