Abstract
The utility model discloses an automatic gear shifting device for an electric vehicle. The automatic gear shifting device for the electric vehicle comprises a lead screw and a shifting fork, wherein the lead screw is sleeved with the shifting fork. A round hole is formed in one end of the shifting fork, and a pin is welded in the round hole and protrudes out of the inner wall of the round hole. The lead screw is provided with a spiral groove. According to the automatic gear shifting device for the electric vehicle, the pin is welded on the shifting fork, a shaft is machined to be the lead screw, and therefore the shifting fork moves in the axial direction of the lead screw, and then the automatic gear shifting function is achieved.
Description
Technical field
The utility model relates to a kind of electric motor car automatic shifting device.
Background technique
High to low gear in the gearbox of electro-tricycle, four-wheel wagon conversion in the market is to move up and down along axle direction by shift fork, driving planetary pinion moves and realizes variable block, shift fork moves that to need the people be the projection pulled on shift fork, this axial linear motion can't be controlled with the rotation of rotor, therefore can not realize automatic shifting.
The model utility content
Main purpose of the present utility model is to overcome existing deficiency, and a kind of electric motor car automatic shifting device is provided.
For achieving the above object, the technical solution of the utility model provides a kind of electric motor car automatic shifting device, comprises leading screw and shift fork, and described shift fork is placed in outside described leading screw;
Described shift fork one end contains circular hole, in described circular hole, is welded with pin, and described pin protrudes from described circular-hole internal-wall;
Described leading screw is provided with spiral chute.
Further, described spiral chute width is greater than 3mm, and the degree of depth is greater than 2mm.
Further, described pin slides in described spiral chute.
Compared with prior art, the utility model has the advantage of: by welding pin and axle is processed into to leading screw on shift fork, can realize that shift fork moves axially along leading screw, thereby realize automatic gear change function.
The accompanying drawing explanation
Fig. 1 is the structural representation of a kind of electric motor car automatic shifting of the utility model device;
Fig. 2 is the structural representation of the shift fork of this practical electric motor car automatic shifting device;
Fig. 3 is the structural representation of the leading screw of this practical electric motor car automatic shifting device.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples are used for the utility model is described, but are not used for limiting scope of the present utility model.
The structure of a kind of electric motor car automatic shifting device of the present embodiment as shown in Figure 1, comprises leading screw 3 and shift fork 2, and described shift fork 2 is placed in outside described leading screw 3;
As shown in Figure 2, described shift fork 2 one ends contain circular hole, are welded with pin 1 in described circular hole, and described pin 1 protrudes from described circular-hole internal-wall 2mm;
As shown in Figure 3, described leading screw 3 is provided with spiral chute 4.
Described pin 1 diameter is 3mm.
Described spiral chute 4 width are greater than 3mm, and the degree of depth is greater than 2mm.
Described pin 1 is in 4 li slips of described spiral chute.
Described pin can slide in described spiral chute, and when leading screw rotates, fork is along the leading screw axial motion.
Can be used on electro-tricycle, on electric four-wheel vehicle, when the speed of a motor vehicle, below 20 kilometers/hour the time, use low speed gear, now moment of torsion is large, in climbing, very useful while drawing heavy cargo, when speed reaches more than 20 kilometers/hour, use high gear, now moment of torsion reduces, but speed is accelerated.
The utility model is by welding pin on shift fork and axle is processed into to leading screw, can realize that shift fork moves axially along leading screw, thereby realize automatic gear change function.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art's (referring to non-applicant); under the prerequisite that does not break away from the utility model know-why; also may make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
Claims (3)
1. an electric motor car automatic shifting device, is characterized in that, comprises leading screw and shift fork, and described shift fork is placed in outside described leading screw;
