Embodiment
Below in conjunction with accompanying drawing, the present invention is described in further detail:
As shown in Figure 1, Figure 2 and Figure 3, a kind of electronic or self-clanging gear-shift of gearbox used for electric vehicle, comprise gearbox casing 7, shifting motor 14 and drive screw 1, drive screw 1 is connected with reverse shift fork 4, the drive screw 1 of reverse shift fork 4 both sides is provided with left push nut 2 and right push nut 6, left push nut 2 and be separately installed with a left side between right push nut 6 and reverse shift fork 4 and push away spring 3 and the right side pushes away spring 5, reverse shift fork 4 upper-end surface is provided with three gear grooves 15; The left side of described gearbox casing 7 is provided with left position transducer 8, right side is provided with Position Sensor 12 and right position transducer 13, positioning device mounting hole 16 is offered in the middle part of gearbox casing 7 above described reverse shift fork 4, in mounting hole 16, positioning device is installed, described positioning device comprises adjustment screw 9, stage clip 10 and steel ball 11, steel ball 11 is inserted in the gear groove 15 on reverse shift fork 4, is provided with stage clip 10 between adjustment screw 9 and steel ball 11.
Shifting motor 14 of the present invention provides gear shift power source, drive screw 1, left push nut 2, a left side push away spring 3, reverse shift fork 4, the right side push away the composition such as spring 5, right push nut 6 gear-shifting actuating mechanism, left position transducer 8, Position Sensor 12, right position transducer 13 form position signal reponse system, and adjustment screw 9, stage clip 10, steel ball 11 form gear navigation system with the groove on reverse shift fork 4.
The form that drive screw 1 employing can only be rotated, can not move axially is arranged on gearbox casing 7, left push nut, right push nut 6 drive screw 1 be equipped with, left push nut 2, right push nut 6 can only move axially can not rotate with after the cooperation of gearbox casing 7, the reverse shift fork 4 of gear shift is housed in the middle of them, reverse shift fork 4 be the Spielpassung of energy flexible rotating movement with drive screw 1, left push nut 2, is set with between right push nut 4 and reverse shift fork 4 that a left side pushes away spring 3, the right side pushes away spring 5; The axle head of drive screw 1 and the rotor of shifting motor 14 are connected, and meet power required when driving gear shift; Appropriate location on gearbox casing 7 is equipped with left position transducer 8, Position Sensor 12, right position transducer 13 respectively, for left push nut 2, right push nut 6 provide signal when entering desired location; Positioning device is equipped with in the appropriate location of simultaneously gearbox casing 7, and adjustment screw 9, stage clip 10, steel ball 11 and the groove fit on reverse shift fork 4 play the positioning action of gear.
The working principle of structure of the present invention is:
As shown in Figure 1, be neutral state of the present invention, Position Sensor 12 sends signal notification controller and enters neutral state.When reverse shift fork 4 needs to move to left (assuming that being bottom gear), controller makes shifting motor 14 rotate artificially or automatically sending instruction, thus drive left push nut 2 by the rotation of drive screw 1, right push nut 6 is moved to the left, owing to making a left side push away spring 3 stored energy under the gear shift resistance of reverse shift fork 4 and the effect of spacing resistance, until when the left side energy pushed away stored by spring 3 is greater than the resistance of reverse shift fork 4, reverse shift fork 4 is rapidly to and moves left, right push nut 6 moves to left to bottom gear position simultaneously, left position transducer 8 is made to send the signal that puts in place, notification controller makes shifting motor 14 stop operating, complete and enter bottom gear by neutral gear, as shown in Figure 2.
As shown in Figure 2, for low-gearing regime of the present invention, when needs enter neutral gear (reverse shift fork 4 moves to right), controller makes shifting motor 14 rotate backward artificially or automatically sending instruction, thus pass through the rotation of drive screw 1, drive left push nut 2, right push nut 6 moves right, owing to making the right side push away spring 3 stored energy under the gear shift resistance of reverse shift fork 4 and the effect of spacing resistance, until when the right side energy pushed away stored by spring 3 is greater than the resistance of reverse shift fork 4, reverse shift fork 4 is rapidly to and moves right, left push nut 2 moves to left to neutral position simultaneously, Position Sensor 12 is made to send the signal that puts in place, notification controller makes shifting motor 14 stop operating, complete and enter neutral gear by bottom gear, as shown in Figure 1.
In like manner, reverse shift fork 4 realize by neutral gear continue to move to right enter top gear (assuming that) time, controller makes shifting motor 14 continue to rotate backward artificially or automatically sending instruction, thus pass through the rotation of drive screw 1, drive left push nut 2, right push nut 6 continues to move right, owing to making the right side push away spring 3 stored energy under the gear shift resistance of reverse shift fork 4 and the effect of spacing resistance, until when the right side energy pushed away stored by spring 3 is greater than the resistance of reverse shift fork 4, reverse shift fork 4 is rapidly to and moves right, left push nut 2 moves to left to high range position simultaneously, right position transducer 13 is made to send the signal that puts in place, notification controller makes shifting motor 14 stop operating, complete and enter top gear by neutral gear, as shown in Figure 3.
In like manner realize the operation that can be entered neutral gear by top gear.Whole gearshift procedure realizes the intelligent operation of hommization, achieves the irrealizable function of other mechanical structure.
The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every utilize specification of the present invention and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
