Description
Technical field
The utility model relates to automatic transmission actuator technical field, is specifically related to a kind of AMT shifting device.
Background technique
Existing AMT(Automated Mechanical Transmission, electric control mechanical type automatic speed variator) generally adopts in the shifting device: the structure that as the patent No. is record in the Chinese patent " ecp automatic mechanical transmission gear-selecting and shifting executing mechanism assembly " of ZL200620097228.8.The shifting structure of this patent is: the block selecting axle intersects, is arranged vertically with the gearshift axial cross; The block selecting axle is shifted gears axle in the above below, and the square groove is all arranged in the middle of it.The gearshift axle passes the square groove in the middle of block selecting axle and the gearshift axle, extend in the groove of gearshift shifting block.The bindiny mechanism of two square grooves and shifting axle is comparatively complicated in this structure, the cost height, and entire mechanism do not have interlocking function, causes hanging simultaneously two gears easily and causes synchronizer to damage.
Summary of the invention
The purpose of this utility model is at above-mentioned technical problem, and a kind of AMT shifting device is provided, and this device has interlocking function, can prevent that the shifting device from hanging up two gears simultaneously.
For realizing this purpose, the AMT shifting device that the utility model is designed, comprise the top cover housing, be arranged on the gearshift axle in the top cover housing, be arranged on the axle sleeve between top cover housing and the gearshift axle, be fixed on the shifting shifting block on the gearshift axle, it is characterized in that: it comprises that also sky is enclosed within the interlocking block on the gearshift axle, be fixed on the guide cover on the top cover housing, described shifting shifting block is between the two side of interlocking block, described gearshift axle runs through the two side of interlocking block, the top of described interlocking block is provided with axial long hole, described guide cover is provided with directional post, described directional post is positioned at axial long hole, and with the axial long hole axial sliding fit.
Offer the through hole that is interconnected on described guide cover and the directional post, on the described through hole breather plug is installed.
Described through hole is communicated with the cavity between the interlocking block two side.
Described interlocking block is the inverted U interlocking block, and described axial long hole is opened in the top of inverted U interlocking block, and the gearshift axle runs through the two side of inverted U interlocking block.
Fix by pin between described shifting shifting block and the gearshift axle.
The utility model has prevented effectively that by setting up interlocking block the shifting device from hanging up two gears simultaneously, has guaranteed the stable normal operation of synchronizer.Simultaneously, the utility model makes the venting capability of whole transmission system be significantly improved by integrated breather plug on guide cover, has improved the stability of speed changer.And guide cover can be dismantled at any time, has made things convenient for fault diagnosis and the maintenance of product.

Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments:
AMT shifting device described in Fig. 1 and 2, comprise top cover housing 1, be arranged on the gearshift axle 2 in the top cover housing 1, be arranged on the axle sleeve 3 between top cover housing 1 and the gearshift axle 2, be fixed on the shifting shifting block 5 on the gearshift axle 2, it comprises that also sky is enclosed within the interlocking block 4 on the gearshift axle 2, be fixed on the guide cover 6 on the top cover housing 1, shifting shifting block 5 is between the two side of interlocking block 4, described gearshift axle 2 runs through the two side of interlocking block 4, the top of described interlocking block 4 is provided with axial long hole 8, guide cover 6 is provided with directional post 9, directional post 9 is positioned at axial long hole 8, and with axial long hole 8 axial sliding fits.Above-mentioned gearshift axle 2 can endwisely slip and rotate in a circumferential direction at top cover housing 1.
In the technique scheme, offer the through hole 10 that is interconnected on guide cover 6 and the directional post 9, breather plug 7 is installed on the through hole 10.
In the technique scheme, the cavity that through hole 10 is communicated with between interlocking block 4 two sides.
In the technique scheme, interlocking block 4 is the inverted U interlocking block, and axial long hole 8 is opened in the top of inverted U interlocking block, and gearshift axle 2 runs through the two side of inverted U interlocking block.Be provided with stiffening rib between the two side of described inverted U interlocking block to gain in strength.
In the technique scheme, fix by pin between shifting shifting block 5 and the gearshift axle 2.
In the technique scheme, top cover housing 1 lower end is connected with the speed changer body by locating stud and bolt, and top cover housing 1 top is offered square opening guide cover 6 is installed.
Working procedure of the present utility model is: as shown in Figure 1, in the block selecting process, gearshift axle 2 is move left and right under gear selecting power drives, and 5 while of the shifting shifting block move left and right of fixedlying connected with it realizes gear selecting; Shifting shifting block 5 drives also move left and right of interlocking blocks 4 at this moment, and the directional post 9 of guide cover 6 play the guiding role at this moment.As shown in Figure 2, in shift process, gearshift axle 2 rotates under the effect of gearshift power, drives also rotation of shifting shifting block 5, realizes the gearshift action; 4 position-limiting actions of 6 pairs of interlocking blocks of guide cover this moment, make interlocking block 4 can't rotate fully, be in the selector fork that stretches in the gearbox because the lower end of interlocking block 4 is the same with gearshift shifting block 5, so the interlocking block that can't rotate 4 makes that all shift forks except the selector fork that gearshift shifting block 5 stretches into all can't engage a gear, thereby realizes interlocking function.Axial long hole 8 on the interlocking block 4 make interlocking block 4 relatively guide cover 6 endwisely slip, and the circumferential rotation of interlocking block 4 be directed to cover 6 spacing.Simultaneously in entire work process, breather plug on the guide cover 67 plays the ventilation effect for whole transmission system.
The content that this specification is not described in detail belongs to related domain professional and technical personnel's known prior art.
