Description
Technical field
The utility model relates to a kind of electric motor car, particularly a kind of electric motor car two grades of speed variator systems.
Background technique
At present, two grades of gears designed by existing electro-tricycle are when carrying out transforming gear, need to reduce the speed of a motor vehicle or interrupt power just can carry out shift, but due to gear shift slide block and gear tooth in conjunction with time, due to the velocity transformation of moment, gear shift slide block need overcome the rotary inertia of drive motor, make gear shift slide block and gear tooth can produce very large impact force (especially top gear becomes the situation of bottom gear) instantaneously combining, produce obvious Strike note, gear can be damaged time serious, there is potential safety hazard, also can produce during gear shift preshoot or after the discomfort of frustrating.
Model utility content
The purpose of this utility model is just to provide a kind of electric motor car two grades of speed variator systems that can carry out steady shift.
The purpose of this utility model is realized by such technological scheme, a kind of electric motor car two grades of speed variator systems, comprise the input shaft being positioned at gear box, the declutch shift shaft of jack shaft and band shift fork, described jack shaft is provided with jack shaft one grade of gear, gear shift slide block and secondary gear of intermediate shaft, described input shaft is provided with input shaft one grade of tooth and input shaft second gear tooth of engaging with jack shaft one grade of gear and secondary gear of intermediate shaft respectively, described shift fork is stuck on gear shift slide block, it is characterized in that: on described input shaft, between input shaft one grade of gear and input shaft intermediate gear, be provided with one-way element and reverse gear slide block, described reverse gear slide block is provided with Spring Steel Wire, the other end of described Spring Steel Wire stretches in the position-limited box that is arranged in casing.
Wherein, described one-way element and described input shaft one grade of gear are that integral type is arranged; The inwall of described reverse gear slide block is provided with spiral chute, and described reverse gear slide block is connected with the outer spiral spline be arranged on input shaft by spiral chute.
Owing to have employed technique scheme, the utility model has ingenious, the making and installation advantage easily of design, adopts intense impact suffered when it solving gear shift, avoids the damage of component, not only increase Security and travelling comfort, but also extend the working life of gear.
Accompanying drawing explanation
Accompanying drawing of the present utility model is described as follows:
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail; but the utility model is not limited to these mode of executions; any improvement or alternative on the present embodiment essence spirit, still belongs to the utility model claim scope required for protection.
Embodiment 1: as shown in Figure 1, a kind of electric motor car two grades of speed variator systems, comprise the input shaft 1 being positioned at gear box, the declutch shift shaft 4 of jack shaft 2 and band shift fork 3, described jack shaft 2 is provided with jack shaft one grade of gear 5, gear shift slide block 6 and secondary gear of intermediate shaft 7, described input shaft 1 is provided with input shaft one grade of tooth 8 and input shaft second gear tooth 9 of engaging with jack shaft one grade of gear 5 and secondary gear of intermediate shaft 7 respectively, described shift fork 3 is stuck on gear shift slide block 6, described input shaft 1 is provided with one-way element 11 and reverse gear slide block 12 between input shaft one grade of gear 8 and input shaft intermediate gear 9, described reverse gear slide block 12 is provided with Spring Steel Wire 13, the other end of described Spring Steel Wire 13 stretches in the position-limited box 14 that is arranged in casing.
Wherein, described one-way element 11 with described input shaft one grade of gear 8 for integral type is arranged; The inwall of described reverse gear slide block 12 is provided with spiral chute, and described reverse gear slide block 12 is connected with the outer spiral spline 15 be arranged on input shaft 1 by spiral chute.
In the utility model, when car load advances, drive motor rotates clockwise, drive motor is connected by involute splines with input shaft 1, input shaft 1 is rotated clockwise, now because the effect of outer spiral spline 15 and Spring Steel Wire 13 the other end are subject to the position-limiting action of position-limited box 14, reverse gear slide block 12 is made to do axial motion, input shaft one grade of gear 8 thrown off by boss on reverse gear slide block 12, after reverse gear slide block 12 moves axially to final position, rotate clockwise with input shaft 1, be enclosed within Spring Steel Wire 13 skidding in groove, as long as car load keeps advancing, reverse gear slide block 12 just maintains this state always.
When car load keeps advancing, when top gear switches to bottom gear, jack shaft one grade of gear 5 is because jack shaft 2 is from the trend at a high speed to low speed speed change, so, suddenly accelerate counterclockwise to rotate, band driven input shaft one grade of gear 8 accelerates to rotate clockwise, thus surmounted the original clockwise rotating speed of one-way element 11, one-way element 11 now skids with input shaft one grade of gear 8, the rotation momentum produced because of gear shift is cushioned, the impact force of gear is significantly reduced, until input shaft one grade of gear 8 slows down gradually, when one-way element 11 accelerates to same speed gradually, power is just delivered to jack shaft 2 by input shaft 1 once again.And under gear shift slide block 6 drive of combining at sliding selector shaft with the moment that the gear tooth of jack shaft 2 is combined, only need overcome the rotary inertia of input shaft and gear tooth thereof, because the required rotary inertia overcome is less, gear shift slide block 6 is combined the impact force produced instantaneously with gear tooth also very little, very large Strike note can not be sent, thus realize the smooth transition of gear.
During car load reverse gear, drive motor band driven input shaft 1 rotates counterclockwise, now one-way element 11 skids one grade to transmit and turns round, but because outer spiral spline 15 acts on the position-limiting action being subject to position-limited box 14 with Spring Steel Wire 13 the other end, reverse gear slide block 12 is moved axially agree with to the groove of input shaft one grade of gear 8 on its boss and input shaft one grade of gear 8, in reversing process, the power of input shaft 1 is delivered on input shaft one grade of gear 8 by the outer spiral spline 15 of input shaft 1 with the spiral chute of reverse gear slide block 12, thus when having supplied reversing one-way element 11 skid can not the situation of transferring power, car load achieves normal reverse gear.
