Description
Technical field
The utility model relates to gearbox technology, the gear of specifically a kind of electric motor car.
Background technique
The speed of current electric motor car or the output of moment of torsion are generally decided by the size of electric current, but electric current can only change in certain scope, excursion is limited, there is contradiction in the output facet with hourly velocity and moment of torsion, solving this contradiction the best way is exactly the gear adopting similar fuel-engined vehicle similar, also the gearbox of electric motor car is had at present, shift speed change transfers by the positive and negative of motor the conversion realizing output torque, the process that decelerating through motor stops reversing again is inevitably there is in transfer process, centre has pause and transition in rhythm or melody sensation, use inconvenience, only safety and comfort is all poor.
Model utility content
The purpose of this utility model is to provide a kind of electric vehicle gear box, the conversion of gear is realized by gear shifting stop lever, identical with internal-combustion engine gearbox at shift process, motor still keeps normal work without the need to clockwise and anticlockwise, has simple to operate, turn feature that gear is convenient, safe and reliable.
For achieving the above object by the following technical solutions:
A kind of gear of electric motor car, comprise input shaft, jack shaft and output gear, it is characterized in that: on described jack shaft, be provided with center tooth and spline, jack shaft is also socketed with high gear gear couplings block successively, gearshift tooth hub and low gear gear, wherein high gear gear couplings block and gearshift tooth hub inner edge are provided with the alligator with spline fitted, low gear gear is by bearing or be directly socketed on jack shaft, be equipped with in the side that high gear gear couplings block and low gear gear are adjacent with gearshift tooth hub and be connected tooth hub, connect tooth hub consistent with the groove of gearshift tooth hub outer rim, socket gearshift tooth cover on gearshift tooth hub, the width of gearshift tooth cover is less than gearshift tooth hub and is greater than the width connecting tooth hub, high gear gear couplings block is also socketed unidirectional high gear gear, described input shaft is provided with low-speed output gear and high-speed output gear, and low-speed output gear is meshed with low gear gear, and high-speed output gear is meshed with unidirectional high gear gear, described output gear is meshed with center tooth, described output gear is connected with active conical tooth, and active conical tooth coordinates with by mantle tooth, is provided with semiaxis connecting bushing by mantle tooth, described active conical tooth and being wrapped up by front and rear covers by mantle tooth, the position of the corresponding semiaxis connecting bushing of housing front and rear covers has axis hole.
When the utility model uses, gearshift tooth cover is connected with the gearshift of electric motor car with rope by connecting rod, to be shifted gears tooth hub and high gear gear couplings block or low gear gear couplings by moving gear shift tooth cover, by high gear gear couplings block or low gear gear driven jack shaft at a high speed or low-speed running, and then drive the high speed of output gear or low speed to export by center tooth, being exported by mantle tooth finally by half mandrel connector; The utility model adopts unidirectional high gear gear between high gear gear couplings block and speedy carding process are taken turns simultaneously, reduces resistance when running at high speed, more energy-conservation; And because speed is slower in adopting ratchet during low speed driving, structure is simpler; There is simple to operate, turn feature that gear is convenient, safe and reliable.

Fig. 3 is the structural representation of the utility model input shaft.
Embodiment
As Figure 1-3, a kind of gear of electric motor car, comprise input shaft 1, jack shaft 2 and output gear 3, it is characterized in that: on described jack shaft 2, be provided with center tooth 21 and spline 22, jack shaft 2 is also socketed with high gear gear couplings block 4 successively, gearshift tooth hub 5 and low gear gear 6, wherein high gear gear couplings block 4 and gearshift tooth hub 5 inner edge are provided with the alligator coordinated with spline 22, low gear gear 6 is by bearing or be directly socketed on jack shaft 2, be equipped with in the side that high gear gear couplings block 4 and low gear gear 6 are adjacent with gearshift tooth hub 5 and be connected tooth hub 41, 61, connect tooth hub 41, 61 is consistent with the groove of gearshift tooth hub 5 outer rim, socket gearshift tooth cover 7 on gearshift tooth hub 6, the width of gearshift tooth cover 7 is less than gearshift tooth hub 5 and is greater than connection tooth hub 41, the width of 61, high gear gear couplings block 4 is also socketed unidirectional high gear gear 8, described input shaft 1 is provided with low-speed output gear 11 and high-speed output gear 12, and low-speed output gear 11 6 engages mutually with low gear gear, and high-speed output gear 12 is meshed with unidirectional high gear gear 8, described output gear 3 is meshed with center tooth 21, described output gear 3 is connected with active conical tooth 10, and active conical tooth 10 coordinates 9 with by mantle tooth, is provided with semiaxis connecting bushing 91 by mantle tooth 9, described active conical tooth 10 and by mantle tooth 9 by protecgulum 31 and bonnet parcel 32, the position of the corresponding semiaxis connecting bushing 91 of housing front/rear cover 31,32 has axis hole.
When the utility model uses, gearshift tooth cover is connected with the gearshift of electric motor car with rope by connecting rod, to be shifted gears tooth hub and high gear gear couplings block or low gear gear couplings by moving gear shift tooth cover, and by high gear gear couplings block or low gear gear driven jack shaft at a high speed or low-speed running, and then drive the high speed of output gear or low speed to export by center tooth, being exported by mantle tooth finally by half mandrel connector.
The utility model considers that hourly velocity of running at high speed can not keep constant in addition, time height time low speed motor exported there is larger resistance, cause the waste of output, therefore between high gear gear couplings block and speedy carding process are taken turns, unidirectional high gear gear is adopted, resistance is reduced when running at high speed, more energy-conservation; And because speed is slower in adopting ratchet during low speed driving, structure is simpler; The utility model changes realization gearshift tooth hub by gearshift tooth cover position and links together with low gear gear or high gear gear couplings block, thus realize low speed or output at a high speed, shift process does not almost have pause and transition in rhythm or melody to feel, works smooth-going, and has simple to operate, turn feature that gear is convenient, safe and reliable.
