Embodiment
For above-mentioned purpose of the present utility model, feature and advantage can more be become apparent, below in conjunction with accompanying drawing, specific embodiment of the utility model is described in detail.
The utility model embodiment provides a kind of clutch master cylinder, with reference to Fig. 3, Fig. 4, there is master cylinder oil cylinder (not shown) and the total pump push rod being connected with master cylinder oil cylinder, the shift fork 120 that described total pump push rod comprises rod member 110 and is positioned at one end of rod member 110, is wholely set with described rod member 110.
Described shift fork 120 comprises and is positioned at the collet 122 of rod member 110 axial one end and along collet 122 to two side plates 121 that stretch out away from rod member 110, described two side plates 121 are symmetrical arranged and are parallel to each other with respect to the central shaft of rod member 110; The side face of collet 122 is protruding with many roots bar 123, and this many roots bar 123 is circumferentially spaced apart along collet 122, and every root bar 123, along the extending axially of collet 122, can be all to extend to the other end from one end of collet 122 particularly.
Can see, on the outer circumferential face of the present embodiment collet 122, be formed with rib 123, for the collet of frustoconic shape in prior art, in the time ensureing same outer diameter, can reduce the material of collet 122, thereby shorten its cool time, avoid side plate 121 bending deflection due to supercooling.
The total six roots of sensation of described rib 123 1, and circumferentially spaced apart along described rod member 110.Wherein, for every side plate 121, all have two root bars 123 with it partly on same axial plane, for strengthening the support to side plate 121.Other two root bars 123 and two side plates 121 be radially symmetrical arranged and with side plate 121 not on same axial plane.According to the support situation of collet 122, rib arrangement is set, can makes the intensity of collet 122 in the time of support side plate 121 more balanced.
Wherein, have two along the axially extended groove 110a of rod member 110 on rod member 110, groove 110a extends to collet 122 and runs through collet 122, and and side plate 121 partly between the two root bars 123 in same axial plane.
In other embodiments, the bearing of trend of rib 123 can be not and the parallel to an axis of rod member 110 yet, extends to the other end as long as meet its one end from collet 122.
In other embodiments, the total quantity of described rib 123 and all can setting according to the support strength of collet 122 and cool time with rib 123 quantity of side plate 121 part parallel to an axiss, is not limited to aforesaid way.
Further, referring to Fig. 3, side plate 121 has first end A and the second end B vertically.Two described side plates 121 are along being formed with at least one the first rib 121a on the radially outer surperficial S of described rod member 110, and described the first rib 121a extends to the second end B of described side plate 121 from the first end A of described side plate 121.That is to say, the first rib 121a is positioned on the side surface S of side plate 121 away from rod member 110 central shafts.
In the present embodiment, the middle part between edge and the both sides of the upper both sides of the surperficial S of side plate 121 is all furnished with a first rib 121a.Wherein, the first shape of rib 121a and the profile of corresponding edge that are positioned at edge are basically identical, are positioned at the parallel to an axis of the basic and rod member 110 of the first rib 121a at middle part.The first rib 121a, for directly strengthening intensity and the flexural rigidity of side plate 121, avoids the first rib 121a to occur bending and deformation towards rod member 110 central shaft one sides in cooling procedure.
In other embodiments, the quantity of the first rib 121a can decide according to the needed rigidity of side plate 121, the shape of every rib 121a is also not limited to aforesaid way, extend to the second end B of described side plate 121 as long as meet from the first end A of described side plate 121, can provide the support force of opposing side plate 121 towards rod member 110 central shaft bendings to side plate 121.
Further, on described surperficial S, be also formed with at least one the second rib 121b, described the second rib 121b and described the first rib 121a interconnection.
The quantity of the second rib 121b can be one, also can be many, is set to two in the present embodiment.The second rib 121b is used for directly strengthening the intensity of side plate 121, and supports the first rib 121a, increases the enabling capabilities of the first rib 121a.
Wherein, the width of described the first rib 121a and described the second rib 121b should not arrange too much or too small, if width is excessive, can make extend cool time, if width is too small, can cause injection moulding time, in mould, can not form liquid stream smoothly, affect formed product.Described the first rib 121a and the optional width D scope of described the second rib 121b are 2mm～3mm, and it is 2mm that width D is set in the present embodiment.
In addition, in side plate 121, there is through hole 124, axially axial vertical with rod member 110 of through hole 124, the through hole 124 of two side plates 121 coaxially arranges, and side plate 121 passes through through hole 124 and is connected with pedal (not shown).
Shown in Fig. 3, on the surperficial S of side plate 121, be also formed with the 3rd rib 121c, it is upper that described the 3rd rib 121c is positioned at described surperficial S, along the circumferential extension of described through hole 124 and ringwise.
In the position of through hole 124, corresponding the first rib 121a and the second rib 121b are interrupted, and all connect in the 3rd rib 121c.
In other embodiments, the 3rd rib 121c can be also the arc section circumferentially extending along through hole 124, and not ringwise.
Although the utility model discloses as above, the utility model is not defined in this.Any those skilled in the art, not departing from spirit and scope of the present utility model, all can make various changes or modifications, and therefore protection domain of the present utility model should be as the criterion with claim limited range.
