Description
Technical field
The invention belongs to vehicle transmission technical field, specifically, particularly a kind of electrically controlled gearbox final controlling element.
Background technique
At present, the block selecting device of automobile gear shift actuator, gearshift can adopt motor-driven structure, hydraulic driving structure or air pressure driving structure.
Hydraulically powered shift-selecting and changing actuating mechanism has compact structure, move advantage accurately, but that its complex structure, part processing precision require is high, quality control is difficult, need set up hydraulic power supply, and manufacturing expense is high.
The shift-selecting and changing actuating mechanism that air pressure drives has economic environmental protection, part is manufactured less demanding advantage, and can utilize the existing gas pressure source on automobile, but its block selecting device need be realized three or four block selecting positions by a plurality of cylinders, and need a plurality of electromagnetic valve inlet, outlet of configuration, there is complex structure, shift-selecting and changing actuating mechanism take up room large and the poor defect of versatility.
Motor-driven shift-selecting and changing actuating mechanism adopts a motor that power is provided, and must correspondingly be equipped with reduction gearing mechanism, and not only complex structure, assemble difficulty, and efficiency of assembling is low, and cost of production is high, is unfavorable for batch production.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of electrically controlled gearbox final controlling element simple in structure, reliable.
Technological scheme of the present invention is as follows: a kind of electrically controlled gearbox final controlling element, comprise shifting shaft (1), one end of described shifting shaft (1) is stretched in the rotor of block selecting motor (5), and with the rotor screw-thread fit of block selecting motor (5), the axle body of shifting shaft (1) is arranged in the inner splined hole of elevating arc (2) one end, two kinds of spline fitted, the other end of elevating arc (2) is meshed with small gear (3), and this small gear (3) is sleeved on the output shaft of the gear motor (4) of seting out.
Adopt above technological scheme, when carrying out variable block, first start block selecting motor, make the rotor running of block selecting motor, owing to forming screw pair between the rotor of block selecting motor and shifting shaft, the rotor banding of block selecting motor is moved gear shaft along its axis moving linearly, and spline fitted between shifting shaft and elevating arc, can not affect elevating arc during shifting shaft straight line motion; Shifting shaft moves to behind the block selecting position needing, and block selecting motor stops, and the gear motor rotation of seting out, the output shaft of the gear motor of seting out drives pinion rotation, in the time of pinion rotation, by elevating arc, drives shifting shaft to turn over several angle, thereby realize, puts into gear.
As can be seen here, one aspect of the present invention is simple in structure, compact, easy disassembling, and assembling and easy to maintenance, manufacturing efficiency is high, is conducive to batch production; On the other hand, the present invention is easy to control, easy and simple to handle, and goes slick, reliably, can guarantee shifting accuracy of action.
The internal spline nose end of described elevating arc (2) is supported on gear box casing by thrust bearing (6), and above structure, when guaranteeing that elevating arc goes slick, has limited the axial-movement of elevating arc along shifting shaft, thereby has effectively avoided shifting to produce error.
The displacement transducer and the angle transducer that match with shifting shaft (1) are housed on described gear box casing, described displacement transducer is connected with block selecting motor (5) by control circuit, the straight line motion of displacement transducer induction shifting shaft, and by control circuit make block selecting motor in time, shut down exactly, to guarantee accurate block selecting; Described angle transducer is connected with the gear motor (4) of seting out by control circuit, rotatablely moving of angle transducer induction shifting shaft, and by control circuit make to set out gear motor in time, shut down exactly, to prevent the phenomenon of gearshift dislocation or the failure of putting into gear.
In order to make structure compacter, and be conducive to install and arrange, described block selecting motor (5) and the gear motor (4) of seting out are positioned at the same side of elevating arc (2).
Beneficial effect: the present invention is by mating with the driving torque of gearbox shifting axle the output torque of set out gear motor and step electric machine, realize block selecting and gearshift function, have simple in structure, assemble easy, easy and simple to handle, and the feature such as go slick, reliable, can guarantee shifting accuracy of action.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with drawings and Examples, the invention will be further described:
As shown in Figure 1, shifting shaft 1 is positioned at the housing of gearbox, and one end of this shifting shaft 1 is stretched in the rotor of block selecting motor 5, and with the rotor screw-thread fit of block selecting motor 5, the rotor of shifting shaft 1 and block selecting motor 5 forms screw pair.On the axle body at shifting shaft 1 middle part, be processed with external splines, the axle body at shifting shaft 1 middle part is arranged in the inner splined hole of elevating arc 2 one end, two kinds of spline fitted, and the internal spline nose end of elevating arc 2 is supported on gear box casing by thrust bearing 6.The other end of described elevating arc 2 is meshed with small gear 3, and this small gear 3 is sleeved on the output shaft of the gear motor 4 of seting out.Described block selecting motor 5 and the gear motor 4 of seting out are positioned at the same side of elevating arc 2, and block selecting motor 5 is all arranged on the housing of gearbox with the gear motor 4 of seting out.
