Beginning focuses on the research of pure electric automobile.At present, electric car in the market mostly using two speed transmission, hold by the gearshift of two speed transmission
There is a manually and automatically two ways in row mechanism, and hand shift is more demanding to driving technology and transmission system, existing automatic
Gear-shifting actuating mechanism is complicated, and volume is big, is unsuitable for being arranged in the limited electric car in complicated, space, therefore
The applicant devise a kind of shift process smooth out, be quick on the draw, is simple in structure, small two speed transmission gearshift execution machine
Structure.
Utility model content
In view of the deficiencies of the prior art, smooth out, be quick on the draw the purpose of this utility model is to provide a kind of shift process,
Simple in structure, small two speed transmission gear shifting actuating mechanism.
In order to solve the above-mentioned technical problem, the utility model employs following technical solution：
A kind of gear shifting of two speed transmission mechanism, including motor, worm screw, turbine, turbine wheel shaft, shift fork and shift fork axle, the snail
The output axis connection of bar and motor, the turbine wheel shaft are set with worm screw vertical interlaced, and the turbine is mounted on turbine wheel shaft, and whirlpool
Wheel and worm engaging；The shift fork axle is set with worm screw and turbine wheel shaft vertical interlaced, and the shift fork is mounted in shift fork axle, and whirlpool
Wheel is connected with shift fork；Cam structure is provided on the turbine, the gear teeth of the turbine are arranged on cam structure, pass through
The rotary motion of worm screw, is converted into the linear reciprocating motion of turbine by turbine and the cooperation of worm screw, and then it is past that shift fork is driven to make again
Linear motion.
During utility model works, motor drives worm screw to rotate, and worm screw engages with turbine, converts rotational motion to reciprocal
Linear motion, due to being provided with cam structure on turbine, during worm drive turbine, turbine can form reciprocal straight
Line moves, and then shift fork is driven to do reciprocating linear motion.Compared with the gear shifting actuating mechanism of existing two speed transmission of electric car, this
The structure of utility model is simpler, small, can adapt to the installation requirements of different spaces, meanwhile, the utility model utilizes
The cooperation of worm screw and turbine is driven, and stable drive is quick on the draw.
Preferably, connecting seat is provided on the shift fork, open slot is provided on the connecting seat, is set on the turbine
Have a connector, the connector is mounted in open slot, and connector is fixed on by axis pin on connecting seat, enable shift fork with
Turbine does reciprocating linear motion.
Preferably, the connector is structure as a whole with turbine.
Compared with prior art, the beneficial effects of the utility model are：
The structure of the utility model is simpler, small, can adapt to the installation requirements of different spaces, meanwhile, this reality
It is driven with the new cooperation using worm screw and turbine, stable drive is quick on the draw.
Description of the drawings
Fig. 1 is the structure diagram of the utility model.
Specific embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
As shown in Figure 1, a kind of gear shifting of two speed transmission mechanism, including motor 1, worm screw 2, turbine 3, turbine wheel shaft 4, shift fork 5
With shift fork axle 6, the worm screw 2 and the output shaft of motor 1 are connected by shaft coupling, and the turbine wheel shaft 4 is vertical with worm screw 2 to be handed over
Mistake is set, and the turbine 3 is mounted on turbine wheel shaft 4, and turbine 3 is engaged with worm screw 2；The shift fork axle 6 and worm screw 2 and turbine wheel shaft
4 vertical interlaceds are set, and the shift fork 5 is mounted in shift fork axle 6, and turbine 3 is connected with shift fork 5；It is set on the turbine 3
There is cam structure, the gear teeth of the turbine 3 are arranged on cam structure, by the cooperation of turbine 3 and worm screw 4, by worm screw 2
Rotary motion is converted into the linear reciprocating motion of turbine 3, and then shift fork 5 is driven to do reciprocating linear motion again.
During utility model works, motor 1 drives worm screw 2 to rotate, and worm screw 2 engages with turbine 3, converts rotational motion to
Linear reciprocating motion, due to being provided with cam structure on turbine 3, during worm screw 2 drives turbine 3,3 meeting of turbine
Linear reciprocating motion is formed, and then shift fork 5 is driven to do reciprocating linear motion.Gearshift with existing two speed transmission of electric car performs
Mechanism compares, and the structure of the utility model is simpler, small, can adapt to the installation requirements of different spaces, meanwhile, this reality
