Abstract
The invention relates to an automobile synchronizer which can enhance conical-surface torque. A cone ring is provided with a first concave cavity and a second concave cavity, a cone body is provided with a first protruding shoulder and a second protruding shoulder which are matched with the first concave cavity and the second concave cavity respectively, two friction conical-surface pairs are formed between the first concave cavity and the first protruding shoulder, and a friction conical-surface pair is formed between the second concave cavity and the second protruding shoulder. Namely, two members form three friction conical-surface pairs, installation space can be saved by 5%-10% compared with a similar multi-conical-surface synchronizer using four members to form three friction conical-surface pairs only. As for concentricity, as the inner surface of the first protruding shoulder is provided with a blind hole, a first elastic element is arranged in the blind hole, the concentricity of the cone ring and the cone body is guaranteed, and the phenomenon of vibration of the cone ring or the cone body is avoided further.

As the restriction of the invention, this first cavity, the second cavity circumferentially arrange along conical ring, and integral body is class W shape.
As the further restriction of the invention, this first convex shoulder, the second convex shoulder circumferentially arrange along cone, and integral body is class M shape.
As the further restriction of the invention, this first convex shoulder internal surface is provided with blind hole, is provided with the second elastic element in this blind hole.
As further limiting again of the invention, also comprise and the locating column coordinating at tooth hub internal tooth casing, this locating column is pressed in tooth hub slide block.
As further limiting again of the invention, it is characterized in that, the direction that this locating column is pressed into slide block is provided with the first elastic element.
As further limiting again of the invention, it is characterized in that, between this conical ring and cone, form oil leab.
Adopt the beneficial effect of the invention as follows:
(1) on installing space, conical ring is provided with the first cavity, the second cavity, this cone is provided with first convex shoulder, second convex shoulder suitable with the first cavity, the second cavity, between the first cavity and the first convex shoulder, form two groups of cones of friction secondary, between the second cavity and the second convex shoulder, form one group of cone of friction secondary, two component form three groups of cones of friction pairs, and four component in similar multi-cone synchronizer just form three groups of cones of friction pairs, the space that can save 5%-10%;
(2) on cost, compare with similar double taper synchronizer, can reduce by 30% expense;
(3) in friction diameter, synchronous storage level, much larger than single cone synchronizer, to compare with similar double taper synchronizer, the friction diameter of the invention increases by 35% relatively, and synchronous storage level area increases by 30% relatively;
(4) in concentricity, because the first 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

Embodiment
Referring to Fig. 1, in the invention, comprise the tooth hub 3 fixing with axle spline, with the tooth cover 1 of tooth hub spline engagement, with the conical ring 2 of tooth cover spline engagement, with the suitable cone 4 of conical ring, this conical ring 2 is provided with the first cavity 21, the second cavity 22, and they circumferentially arrange along conical ring 2, and integral body is class W shape; This cone 4 is provided with first convex shoulder 41, second convex shoulder 42 suitable with above-mentioned cavity, and they circumferentially arrange along cone 4, and integral body is class M shape.
Between the first cavity and the first convex shoulder, between the outer surface both sides end face of the internal surface both sides end face of the first cavity and the first convex shoulder, form two groups of cones of friction secondary; Between the second cavity and the second convex shoulder, the second cavity internal surface forms one group of cone of friction pair between the end face near the first convex shoulder near the end face of the first cavity and the outer surface of the second convex shoulder.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.
In order to guarantee the concentricity of conical ring 2 and cone 4, these the first convex shoulder 41 internal surfaces are provided with blind hole 43, are provided with the second elastic element 8 in this blind hole.
In addition, the invention also comprises and the locating column 6 coordinating at tooth hub 3 internal tooth casings 1, and this locating column is pressed in tooth hub 3 slide block 5, and the direction that this locating column 7 is pressed into slide block is provided with the first elastic element 7.The conical surface of this conical ring 2 adopts helix structure, and forms oil leab between the oilhole of cone 3.
The working procedure of the invention is as follows:
Before gearshift, tooth cover 1, conical ring 2, tooth hub 3, the first elastic element 7, locating column 6, slide block 5 are with w1 rotation, and cone 4, the second elastic element 8 rotate with w2;
During gearshift, gear shifting force acts on shift fork, and then acts on tooth cover 1, promotes slide block 5 axial motions, and axial force transmission, to conical ring 2, makes it contact with cone 4, due to w1 ≠ w2, produces each other friction.Meanwhile, by tooth hub 3, make conical ring 2 rotate certain position, when cone 4 and conical ring 2 reach synchronous speed, tooth overlaps 1 smoothly and cone 4 engagements, completes gearshift.
