Shape face, arc inclines the top for causing arcwall face closer to inner end, the phase in the middle part of arcwall face towards the inner end of driving cog
Tangent line is 8-12 ° with the angle a of vertical direction.
Above-mentioned speed change gear gearshift is slim and graceful, long service life, interior conical ring（High-grade ring i.e. in lock unit）Lateral part
It is circumferential uniformly to offer three lightening grooves, drilled with the side wall of each lightening grooves, spring eye is processed on interior conical ring,
The axis translation of spring eye can be tangential on interior conical ring outer wall and perpendicular to inner cone ring axis, and the aperture of spring eye is towards clockwise
Direction is arranged, and interior conical ring offers the mounting hole for axially penetrating through at the aperture of each spring eye, only locks with what low-grade ring was connected
Pin is arranged through mounting hole, and spring is placed with spring eye；When upshifting, spring is by the only lock pin compression in mounting hole, bullet
Spring deformation provides gearshift torque-feedback, and when changing bottom gear, the elastic force of spring causes interior conical ring to reset, but stops in use
Lock pin not only causes to be compressed axially to spring, also causes spring skew deformation, have impact on the using effect of spring, or even spring
Top deflects past the sliding that can hinder only lock pin more sometimes.
The content of the invention
The purpose of this utility model is for the above-mentioned problems in the prior art, there is provided one kind causes spring works
Stablize, stop lock pin slip smoothly lock unit top grade ring structure.
The purpose of this utility model can be realized by following technical proposal：A kind of medium-to-high grade ring structure of lock unit, including
High-grade ring annular in shape, the lateral part of described high-grade ring circumferentially uniformly offers several lightening grooves, and the one of each lightening grooves
Side wall offers spring eye, and the axis translation of spring eye can be tangential on the outer wall of high-grade ring and can be perpendicular to the axle of high-grade ring
Line, the aperture unification of spring eye is arranged towards clockwise or counterclockwise, and described high-grade ring is in each spring eye
The mounting hole axially penetrated through for only lock pin is passed through is offered at aperture, described spring eye is built with spring, it is characterised in that institute
The spring stated has for contradicting the supporter for stopping lock pin in the apical support of spring eye, and the external diameter of described supporter is less than or waits
In the aperture of spring eye, described supporter part is located in spring eye and supporter can slip into spring eye when supporter stress
In.
The setting that this lock unit top grade ring structure passes through supporter, it is to avoid spring top directly contradicts only lock pin, only lock pin
Sliding do not result in the excessive skew deformation of spring, spring works good stability, supporter is supported under the elastic force effect of spring
Touch when only lock pin, supporter part is located in spring eye, without departing from spring eye in such supporter slipping, work is steady
It is fixed, also cause the slip of only lock pin smooth.
In a kind of above-mentioned medium-to-high grade ring structure of lock unit, described supporter is cylindrical and coaxially sets with spring eye
Put.
In a kind of above-mentioned medium-to-high grade ring structure of lock unit, described supporter is used to contradict the resistance surface of only lock pin and is
Recessed arcwall face.So arcwall face can preferably fit the outer peripheral face of only lock pin, realize contact of the face with face, contradict effect
It is good.
In a kind of above-mentioned medium-to-high grade ring structure of lock unit, described supporter has and extends and penetrate into spring eye
Support column in spring.Support column plays support and guide effect to spring, and spring axial direction compression process is smooth, offsets deformation
Little, spring works are stable.
Used as another kind of situation, in a kind of above-mentioned medium-to-high grade ring structure of lock unit, described supporter is spherical
Steel ball.
Compared with prior art, the medium-to-high grade ring structure of this lock unit can cause spring works good stability, and supporter is supported
Tactile effect is good, long service life, and only lock pin slides smooth.

Specific embodiment
The following is specific embodiment of the utility model and combine accompanying drawing, further is made to the technical solution of the utility model
Description, but this utility model is not limited to these embodiments.
As shown in figure 1, the medium-to-high grade ring structure of this lock unit includes high-grade ring 1 annular in shape, the lateral part circumference of high-grade ring 1
Three lightening grooves 2 are uniformly offered, the side wall of each lightening grooves 2 offers spring eye 3, the axis translation energy of spring eye 3
It is tangential on the outer wall of high-grade ring 1 and can sets towards clockwise direction perpendicular to the axis of high-grade ring 1, the aperture unification of spring eye 3
Put, high-grade ring 1 offers the mounting hole 4 axially penetrated through for only lock pin is passed through at the aperture of each spring eye 3, in spring eye 3
Equipped with spring 5, spring 5 has for contradicting the supporter 6 for stopping lock pin in the apical support of spring eye 3, and the external diameter of supporter 6 is less than
The aperture of spring eye 3, supporter 6 coordinates with the inwall gap of spring eye 3, after supporter 6 contacts at only lock pin, supporter 6
Divide and be located in spring eye 3, and supporter 6 can be slipped in spring eye 3 when 6 stress of supporter.During actual manufacture, spring eye 3
Aperture can be unified towards counterclockwise arranging, and the external diameter of supporter 6 can be equal to the aperture of spring eye 3.
Further describe in detail, supporter 6 is cylindrical in the present embodiment and is coaxially disposed with spring eye 3, supporter 6 have to
Extend and penetrate the support column 7 in spring 5 in spring eye 3.During actual manufacture, in order to preferably contradict effect, use supporter 6
The resistance surface for stopping lock pin in conflict is recessed arcwall face.
The setting that this lock unit top grade ring structure passes through supporter 6, it is to avoid the top of spring 5 directly contradicts only lock pin, supports
Post 7 plays support and guide effect to spring 5, and it is smooth that spring 5 is compressed axially process, and skew deformation is little, the job stability of spring 5
Good, when supporter 6 contacts at only lock pin under the elastic force effect of spring 5, the part of supporter 6 is located in spring eye 3, so against
Without departing from spring eye 3, working stability in the slipping of part 6, the only lock pin slip for being located against the conflict of part 6 is smooth.
Specific embodiment described herein is only explanation for example to this utility model spirit.This utility model institute
