Technical field
The present invention relates to field of automobile, refer to a kind of automatic transmission case electricity powered shift-selecting and changing actuating mechanism especially.
Background technique
Along with socioeconomic development, automobile has become indispensable traffic and means of transportation.Existing automobile is all provided with gearbox, and the speed changer in gearbox mainly contains manual transmission (MT), hydraulic automatic speed variator (AT), Automatic mechanical transmission (AMT).
Manual transmission is as occurring speed changer the earliest, and its technology unusual maturation, mainly carrys out the power of Transmission Engine by the engagement of gear.On Domestic market, a lot of vehicle all assembles manual transmission, especially wide dumper.The low price of manual transmission, technology maturation, pure mechanical structure can improve reaction velocity, fuel-economizing is good, maintaining cost is low.But because the operation intensity of a lot of vehicle is high, also make the shortcoming of traditional manual gearbox also show out: manipulation difficulty is large, driving comfortability is poor, manipulation strength is large, and if also can oil consumption be increased not in time for gearshift fresh driver is inaccurate.
The compare manual transmission operation of transmission of hydraulic automatic speed variator is convenient, but its efficiency is low, it is difficult to manufacture, maintaining is difficult, cost is high.
And Automatic mechanical transmission remains most mechanisms of former hand gear box assembly, just the operating mechanism automatic controller of its hand gear is replaced, have that production inheritance is good, reforming cost is low, the advantage of instant effect, and the usability of vehicle can be improved by the optimal design of software comprehensively.But the block selecting of existing Automatic mechanical transmission, gearshift unreasonable structure, cause fuel economy and power character all bad.
Summary of the invention
The technical problem to be solved in the present invention is to provide the low automatic transmission case electricity powered shift-selecting and changing actuating mechanism of the simple cost of a kind of structure.
In order to achieve the above object, the embodiment of the present invention proposes a kind of automatic transmission case electricity powered shift-selecting and changing actuating mechanism, comprises gear selection mechanism and gearshift;
Wherein said gear selection mechanism comprises block selecting motor, block selecting shifting block, and described block selecting motor is provided with block selecting axle, and described block selecting axle is screw, one end of described block selecting shifting block to be socketed on described block selecting axle and can along described block selecting axle move axially carry out block selecting;
Wherein said gearshift comprises shift motor, gear shifting pulling head, and described shift motor is provided with shifting shaft, and described shifting shaft is splined shaft, and described gear shifting pulling head is socketed in described shifting shaft to shift gears with described shifting shaft rotation; And described block selecting shifting block and described gear shifting pulling head link to drive described gear shifting pulling head to move to neutral gear position in target gear groove when described block selecting shifting block moves.
Wherein, block selecting shifting block is socketed on block selecting axle, and realizes linking by connecting rod and gear shifting pulling head.
Wherein, also comprise fixed bearing, the far-end of wherein said block selecting axle and shifting shaft is all fixed on described fixed bearing.
The beneficial effect of technique scheme of the present invention is as follows:
Above-mentioned automatic transmission case electricity powered shift-selecting and changing actuating mechanism, is realized the straight line motion of gear shifting pulling head, and is realized the rotation of gear shifting pulling head by shift motor by step electric machine and block selecting shifting block.Electrical control automatic manual transmission case shifting can be realized by simple structure like this, VE Vehicle Economy and power character can be improved.

Embodiment
For making the technical problem to be solved in the present invention, technological scheme and advantage clearly, be described in detail below in conjunction with accompanying drawing and instantiation.
The embodiment of the present invention, for the block selecting of Automatic mechanical transmission in prior art, gearshift unreasonable structure, causes the problem that fuel economy and power character are all bad, proposes a kind of automatic transmission case electricity powered shift-selecting and changing actuating mechanism.
As shown in Figure 1, a kind of automatic transmission case electricity powered shift-selecting and changing actuating mechanism that the embodiment of the present invention provides, comprises gear selection mechanism and gearshift.
Wherein said gear selection mechanism comprises block selecting motor 1, block selecting shifting block 3, described block selecting motor 1 is provided with block selecting axle 2, described block selecting axle 2 is screw, one end of described block selecting shifting block 3 to be socketed on described block selecting axle 2 and can along described block selecting axle move axially carry out block selecting.
Wherein, described gearshift comprises shift motor 5, gear shifting pulling head 7, and described shift motor 5 is provided with shifting shaft 6, and described shifting shaft 6 is splined shaft, and described gear shifting pulling head 7 is socketed in described shifting shaft 6 to shift gears with described shifting shaft 6 rotation; And described block selecting shifting block 3 and described gear shifting pulling head 7 link to drive described gear shifting pulling head 7 to move to neutral gear position in target gear groove when described block selecting shifting block 3 moves.
As shown in Figure 1, this block selecting shifting block 3 is socketed on block selecting axle 2, and realizes linking by connecting rod and gear shifting pulling head 7.
As shown in Figure 1, also comprise fixed bearing 4, the far-end of wherein said block selecting axle 2 and shifting shaft 6 is all fixed on described fixed bearing 4.
Specific works process of the present invention is as follows:
Gear selection mechanism drives block selecting shifting block 3 to carry out block selecting by block selecting motor 1, and gearshift drives gear shifting pulling head 7 to shift gears by shift motor 5.Wherein the pto=power take-off of block selecting motor 1 is as shift selection shaft 2, and this shift selection shaft 2 is screw, with by the straight line motion of the converting rotary motion of block selecting motor 1 for block selecting shifting block 3.Because block selecting shifting block 3 and gear shifting pulling head 7 link, gear shifting pulling head 7 neutral gear position moved in target gear groove therefore can be driven to complete block selecting action.And the pto=power take-off of shift motor 5 is as shifting shaft 6, and this shifting shaft 6 is splined shaft; Can be the rotary motion of gear shifting pulling head 7 like this by the converting rotary motion of the pto=power take-off of shift motor 5, to complete gear shifting action.
