Description

A kind of gearbox shifting Effector

Technical field

The utility model belongs to gearbox field, is specifically related to a kind of gearbox shifting Effector.

Background technique

Due to the market demand, speed ratio not of the same race is had to configure with money gearbox.This is often through gear pair indivedual in adjustment gearbox and change the realization of indivedual shift fork moving direction.In order to change shift fork moving direction when not affecting riding manipulation, reversing arrangement must be increased in upper cover.

Traditional design increases commutating structure above the shift fork needing change moving direction, needs shift fork and declutch shift shaft relative movement during gearshift.Its advantage is that space arranges that easily shortcoming is: gearshift resistance is excessive, and gearshift feel is bad; Declutch shift shaft needs to lengthen, and corresponding upper cover declutch shift shaft hole machined requires high, increases gearbox weight and cost.

Model utility content

The purpose of this utility model is to provide a kind of gearbox shifting Effector, and to overcome the defect that above-mentioned prior art exists, the utility model can reduce surface friction drag, reduce gear shifting force, improve gearshift feel, and gearbox weight can be alleviated, reduce gearbox cost.

For achieving the above object, the utility model adopts following technological scheme:

A kind of gearbox shifting Effector, comprise the first declutch shift shaft, the second declutch shift shaft and the 3rd declutch shift shaft that be arranged in parallel, three interspersed being arranged on of declutch shift shafts cover, on cover and be also provided with reversing arrangement, reversing arrangement can around its central rotation, the two ends of reversing arrangement are connected with shifting block and the 3rd declutch shift shaft respectively, and shifting block can drive the 3rd declutch shift shaft by reversing arrangement, and the 3rd declutch shift shaft is fixedly connected with shift fork.

Further, reversing arrangement drives the 3rd declutch shift shaft by the first guide block be fixed on the 3rd declutch shift shaft.

Further, the top and bottom of reversing arrangement are equipped with draw-in groove, and draw-in groove and the shifting block of upper end are connected, and draw-in groove and first guide block of lower end are connected.

Further, the length of the first declutch shift shaft and the second declutch shift shaft is all less than the 3rd declutch shift shaft.

Compared with prior art, the utility model has following useful technique effect:

Reversing arrangement of the present utility model is contained in and covers, can around central rotation, shifting block can drive the 3rd declutch shift shaft by reversing arrangement, and then drive the shift fork be fixed on the 3rd declutch shift shaft, because shift fork and the 3rd declutch shift shaft are fixed, avoid the relative movement of shift fork and the 3rd declutch shift shaft, reduce surface friction drag, reduce gear shifting force, improve gearshift feel.

Further, there is notch at the two ends of reversing arrangement, one end draw-in groove is used for blocking the first guide block, the other end, for receiving external action (namely receiving the action of shifting block), when shifting block moves, drives reversing arrangement motion, reversing arrangement drives the first guide block motion, first guide block drives the 3rd declutch shift shaft, and the 3rd declutch shift shaft drives shift fork, thus achieves shifting block and shift fork moves in the opposite direction.

Further, shorten the length of the first declutch shift shaft, the second declutch shift shaft, above cover and can reduce corresponding shift fork axis hole, process convenient, but also alleviate gearbox weight, reduce gearbox cost.

Embodiment

Below in conjunction with accompanying drawing, the utility model is described in further detail:

See Fig. 2 and Fig. 3, a kind of gearbox shifting Effector, comprise the first declutch shift shaft 4 be arranged in parallel, second declutch shift shaft 5 and the 3rd declutch shift shaft 6, three interspersed being arranged on of declutch shift shafts cover, the length of the first declutch shift shaft 4 and the second declutch shift shaft 5 is all less than the 3rd declutch shift shaft 6, on cover and be also provided with reversing arrangement 2, reversing arrangement 2 can around its central rotation, the two ends of reversing arrangement 2 are connected with shifting block and the 3rd declutch shift shaft 6 respectively, and shifting block can drive the 3rd declutch shift shaft 6 by reversing arrangement 2, reversing arrangement 2 drives the 3rd declutch shift shaft 6 by the first guide block 3 be fixed on the 3rd declutch shift shaft 6, the top and bottom of reversing arrangement 2 are equipped with draw-in groove, draw-in groove and the shifting block of upper end are connected, draw-in groove and first guide block 3 of lower end are connected, 3rd declutch shift shaft 6 is fixedly connected with shift fork 1.

Be described in further detail below in conjunction with the implementation process of accompanying drawing to model utility:

See Fig. 1, in conventional construction, the first declutch shift shaft 4, second declutch shift shaft 5, the 3rd declutch shift shaft 6 are all contained in cap bore, can move vertically.The fluted design in shift fork 1 upper end, empty set also can relative first declutch shift shaft 4 axial motion on the first declutch shift shaft 4.First guide block 3 and all fluted design of the second guide block 7, the two is all rigidly connected with the 3rd declutch shift shaft 6, the second guide block 7 also has the groove receiving outside action (namely receiving the action of shifting block).Reversing arrangement 2 is contained in and covers, can around central rotation, and its two ends are stuck in the first guide block 3 with the groove on shift fork 1, can move thereupon.Mechanism kinematic relation is as shown by arrows: when shifting block moves, the second guide block 7 is driven to move, second guide block 7 drives the 3rd declutch shift shaft 6,3rd declutch shift shaft 6 drives the first guide block 3, first guide block 3 drives reversing arrangement 2, reversing arrangement 2 drives shift fork 1 again, thus achieves shifting block and shift fork moves in the opposite direction.

See Fig. 2 and Fig. 3, in structure described in the utility model, the first declutch shift shaft 4, second declutch shift shaft 5, the 3rd declutch shift shaft 6 are all contained in upper cover, and the length of the first declutch shift shaft 4 and the second declutch shift shaft 5 can be less than the 3rd declutch shift shaft 6, and three all can move vertically.Shift fork 1, first guide block 3 is rigidly connected with the 3rd declutch shift shaft 6 respectively.Reversing arrangement 2 is contained in and covers, can around the central rotation of himself, and there is notch at two ends, and one end draw-in groove is used for blocking the first guide block 3, and the other end is for receiving external action (namely receiving the action of shifting block).Reversing arrangement 2 drives the first guide block 3 axial motion when rotating.Mechanism kinematic relation is as shown by arrows: when shifting block moves, drive reversing arrangement 2 to move, reversing arrangement 2 drives the first guide block 3 to move, and the first guide block 3 drives the 3rd declutch shift shaft 6,3rd declutch shift shaft 6 drives shift fork 1, thus achieves shifting block and shift fork moves in the opposite direction.

Structure of the present utility model avoids the relative movement of shift fork 1 and the 3rd declutch shift shaft 6, reduces surface friction drag, reduces gear shifting force, improves gearshift feel.Shorten the length of the first declutch shift shaft 4, second declutch shift shaft 5, corresponding upper cover does not need shift fork axis hole, alleviates gearbox weight, reduces gearbox cost.
