The speed change mechanism comprises an input shaft, an intermediate shaft and an output gear, wherein higher gear connection blocks, shifting gear hubs and bottom gears are arranged in sequence on the intermediate shaft in a sleeving way; the inner edges of the higher gear connection blocks and the shifting gear hubs are provided with tooth keys matched with splines; one side, which is adjacent to the shifting gear hubs, of each higher gear connection block and each bottom gear is provided with a connection gear hub; the connection gear hubs are accordant with the insection on the outer edges of the shifting gear hubs; shifting gear sleeves are arranged on the shifting gear hubs in a sleeving way; the widths of the shifting gear sleeves are smaller than the shifting gear hubs and greater than the widths of the connection gear hubs; one-way higher gears are arranged on the higher gear connection blocks in a sleeving way. By adopting the speed change mechanism, the shifting gear hubs and the bottom gears or the higher gear connection blocks are linked by changing the positions of the shifting gear sleeves, so that low-speed or high-speed output is realized, the pause feel is almost avoided in a shifting process, working becomes smooth, and the performance is stable.

Description

A kind of gear of electric motor car
Technical field
The present invention 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, shifted is transfer 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.
Summary of the invention
The object of the present invention is to provide a kind of electric vehicle gear box, the conversion of gear is realized by speed change lever, identical with internal-combustion engine gearbox at gearshift procedure, motor still keeps normal work without the need to clockwise and anticlockwise, have simple to operate, turn convenient, the safe and reliable feature of shelves.
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-grade gear couplings block successively, gear shift tooth hub and low regime clutch, its medium-to-high grade gear couplings block and gear shift tooth hub inner edge are provided with the alligator with spline fitted, low regime clutch is by bearing or be directly socketed on jack shaft, be equipped with in the side that high-grade gear couplings block and low regime clutch are adjacent with gear shift tooth hub and be connected tooth hub, connect tooth hub consistent with the groove of gear shift tooth hub outer rim, gear shift tooth hub is socketed gear shift tooth cover, the width of gear shift tooth cover is less than gear shift tooth hub and is greater than the width connecting tooth hub, high-grade gear couplings block is also socketed unidirectional high-grade 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 regime clutch, and high-speed output gear is meshed with unidirectional high-grade 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 present invention uses, gear shift tooth cover is connected with the gearshift mechanism of electric motor car with rope by connecting rod, by mobile gear shift tooth cover, gear shift tooth hub is connected with high-grade gear couplings block or low regime clutch, jack shaft high speed or low-speed running is driven by high-grade gear couplings block or low regime clutch, 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 present invention simultaneously adopts unidirectional high-grade gear between high-grade gear couplings block and speedy carding process are taken turns, and 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; Have simple to operate, turn convenient, the safe and reliable feature of shelves.

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-grade gear couplings block 4 successively, gear shift tooth hub 5 and low regime clutch 6, its medium-to-high grade gear couplings block 4 and gear shift tooth hub 5 inner edge are provided with the alligator coordinated with spline 22, low regime clutch 6 is by bearing or be directly socketed on jack shaft 2, be equipped with in the side that high-grade gear couplings block 4 and low regime clutch 6 are adjacent with gear shift tooth hub 5 and be connected tooth hub 41, 61, connect tooth hub 41, 61 is consistent with the groove of gear shift tooth hub 5 outer rim, gear shift tooth hub 6 is socketed gear shift tooth cover 7, the width of gear shift tooth cover 7 is less than gear shift tooth hub 5 and is greater than connection tooth hub 41, the width of 61, high-grade gear couplings block 4 is also socketed unidirectional high-grade 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 regime clutch, and high-speed output gear 12 is meshed with unidirectional high-grade 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 present invention uses, gear shift tooth cover is connected with the gearshift mechanism of electric motor car with rope by connecting rod, by mobile gear shift tooth cover, gear shift tooth hub is connected with high-grade gear couplings block or low regime clutch, and drive jack shaft high speed or low-speed running by high-grade gear couplings block or low regime clutch, 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 present invention 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-grade gear couplings block and speedy carding process are taken turns, adopt unidirectional high-grade gear, 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 present invention realizes gear shift tooth hub by the position change of gear shift tooth cover and links together with low regime clutch or high-grade gear couplings block, thus realize low speed or output at a high speed, gearshift procedure does not almost have pause and transition in rhythm or melody to feel, works smooth-going, and have simple to operate, turn convenient, the safe and reliable feature of shelves.
