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 keeps off gear changing system, comprise the input shaft 1 be positioned on same level line, jack shaft 2 and shifting fork mechanism, described input shaft 1 is provided with input high speed tooth 3 and input low speed tooth 4, described jack shaft 2 is provided with respectively with input high speed tooth 3 with input the high gear 5 and low speed gear 6 that low speed tooth 4 engages, the synchronizer be connected with high gear 5 and low speed gear 6 is respectively provided with on described jack shaft 2 and between high gear 5 and low speed gear 6, described synchronizer is connected with jack shaft 2 by the spline tooth 7 be arranged on jack shaft 2, described shifting fork mechanism is connected with synchronizer.
Wherein, described jack shaft 2 is provided with low speed ring gear 8 and high speed gear ring 9, described low speed gear 6 is connected with jack shaft 2 with high speed gear ring 9 respectively by low speed ring gear 8 with high gear 5, and described low speed ring gear 8 stretches in synchronizer respectively with high speed gear ring 9 and is connected with synchronizer.
Further describe, above-mentioned synchronizer comprises synchromesh gear hub 10, sliding sleeve 11, synchronizer gear sleeve 12 and synchro converter ring 13, and described high speed gear ring 9 and low speed ring gear 8 to penetrate in synchro converter ring 13 and pass through cone match.
In order to the position of fixing high gear 5 and low speed gear 6, prevent it from offseting, on described jack shaft 2 and the lower end surface of the upper-end surface and low speed ring gear 8 that are positioned at low speed gear 6 is provided with axle sleeve 14 for fixing low speed gear 6; Described high gear 5 is fixed by jack shaft 2 shaft shoulder and synchromesh gear hub 10.
In order to reduce friction, described jack shaft 2 is provided with sliding bearing A15 and sliding bearing B16, described low speed ring gear 8 is connected with jack shaft 2 by sliding bearing A15, and described high speed gear ring 9 is connected with jack shaft 2 by sliding bearing B16.
In the utility model, shifting fork mechanism comprises the declutch shift shaft 18 of band selector fork 17, one end of described declutch shift shaft 18 is provided with three grooves 19, steel ball 20 is provided with in described groove 19, described steel ball 20 is pressed in groove 19 by the adjusting nut 22 of band spring 21, and one end of described selector fork 17 is connected with synchronizer gear sleeve 12.
Working principle of the present utility model is such: when car load advances, drive motor is connected by involute splines with input shaft 1, transmission of power is to input shaft 1, if be now top gear, then input high speed tooth 3 transferring power of input shaft 1 is to the high gear 5 of jack shaft 2, together with high gear 5 connects firmly with high speed gear ring 9, synchronizer gear sleeve 12 is enclosed within the tooth of high speed gear ring 9, and synchronizer gear sleeve 12 and synchromesh gear hub 10 structurally together with rotate, so high gear 5 now on jack shaft 2 to be connected firmly with synchronizer by synchronizer gear sleeve 12 together with rotate, power passes on synchronizer, together with synchromesh gear hub 10 and jack shaft 2 are connected firmly by spline tooth 7, so transmission of power is on jack shaft 2, jack shaft 2 passes through again axle tooth transferring power on differential mechanism.Then when shifting gears, external manipulation mechanism makes declutch shift shaft 18 move axially, steel ball 20 skids off from groove 19, simultaneously selector fork 17 moves axially together along with declutch shift shaft 18, selector fork 17 axially moves together with synchronizer gear sleeve 12, synchronizer gear sleeve 12 skids off from high speed gear ring 9, high gear 5 no longer connects firmly with synchronizer, power cut, selector fork 17 and synchronizer gear sleeve 12 continue to move axially, until steel ball 20 embeds that groove 19 of centre in declutch shift shaft three grooves 19, now steel ball 20 stopper is neutral, power cuts off completely, input shaft 1 power cannot be delivered to jack shaft 2.External manipulation mechanism continues operation, selector fork 17 and synchronizer gear sleeve 12 move toward bottom gear, now jack shaft 2 rotational velocity is higher than the rotational velocity of low speed gear 6, also there is rotary speed difference in the tooth on the tooth on low speed ring gear 8 and synchronizer gear sleeve 12, when synchronizer gear sleeve 12 moves axially because of profile of tooth reason, in advance in conjunction with time produce to rotate to impact and rotate impact and be converted into axial force and make low speed ring gear 8 by axial force, owing to be fitted by the conical surface and together with empty set in low speed ring gear 8 and synchro converter ring 13 one end, this axial force makes low speed ring gear 8 be pressed in the rotation friction that the conical surface produces to increase, as long as synchronizer gear sleeve 12 and synchro converter ring 13 have rotary speed difference, low speed ring gear 8 will produce axial force because of the special tooth profile structure of synchronizer gear sleeve 12, then rotation friction is produced with synchro converter ring 13, this pivoting friction makes low speed tooth overlap rotational velocity gradually near the rotational velocity of synchronizer gear sleeve 12, finally make synchro converter ring 13 identical with synchronizer gear sleeve 12 rotating speed, then synchronizer gear sleeve 12 is inserted in synchro converter ring 13, power is delivered to jack shaft 2 from low speed gear 6.
Whole top gear is in the handoff procedure of bottom gear, and the role that high speed gear ring 9 and low speed ring gear 8 play buffering makes rotation momentum seamlessly transit because of rotation friction, does not cause direct impact.
