Description
Technical field
The present invention relates to a kind of gearbox, relate in particular to a kind of electric automobile gear-box.
Background technique
Automobile is the traffic tool that the mankind are indispensable, but along with the increasing the weight of of environmental pollution, the continuous minimizing of non-renewable resources, people more and more favor the R and D in electric vehicle.Gearbox is the vitals of electric vehicle, traditional gearbox designs complexity, and the conversion inconvenience between high and low shift, grade ability is poor, when especially reversing is shifted gears, gear need to be separated and could shift gears, and gearshift noise is large, and driving comfort is poor.
Summary of the invention
Technical problem to be solved by this invention is: a kind of electric automobile gear-box is provided.
In order to solve the problems of the technologies described above, the technical solution used in the present invention is: electric automobile gear-box, comprise: casing, in described casing, be provided with input shaft and driven shaft, on described input shaft, be provided with the first master gear and the second master gear, between described the first master gear and the second master gear, slide and be provided with synchronizer, on the input shaft of described the first master gear one side, be provided with left back-up ring, on described left back-up ring, be fixedly installed the left magnetic clutch cooperatively interacting with the first master gear, on the input shaft of described the second master gear one side, be provided with right back-up ring, on described right back-up ring, be fixedly installed the right magnetic clutch cooperatively interacting with the second master gear, on described driven shaft, be provided with the first driven gear and the second driven gear, on the casing between described the first driven gear and the first master gear, be provided with transition axis, on described transition axis, be provided with transition gear, described transition gear all engages with the first master gear and the first driven gear, described the second driven gear and the second master gear are intermeshing.
Advantage of the present invention is: above-mentioned electric automobile gear-box, can in the time that shifting gears, high and low shift carry out by magnetic clutch free switching, gearshift efficiency and grade ability are improved, in the time that shifting gears, reverse gear do not need disengage gears simultaneously, can keep gear to engage by synchronizer with excessive gear always, gearshift noise is little, and driving comfort is good.
Accompanying drawing explanation
Fig. 1 is the structural representation of electric automobile gear-box of the present invention.
In figure: 1, casing, 2, input shaft, 3, driven shaft, 4, the first master gear, 5, the second master gear, 6, synchronizer, 7, left back-up ring, 8, left magnetic clutch, 9, right back-up ring, 10, right magnetic clutch, 11, the first driven gear, 12, the second driven gear, 13, transition axis, 14, transition gear.
Embodiment
Describe in detail particular content of the present invention below in conjunction with the drawings and specific embodiments.
As Fig. 1, shown in Fig. 2, electric automobile gear-box, comprise: casing 1, in described casing 1, be provided with input shaft 2 and driven shaft 3, on described input shaft 2, be provided with the first master gear 4 and the second master gear 5, between described the first master gear 4 and the second master gear 5, slide and be provided with synchronizer 6, on the input shaft 2 of described the first master gear 4 one sides, be provided with left back-up ring 7, on described left back-up ring 7, be fixedly installed the left magnetic clutch 8 cooperatively interacting with the first master gear 4, on the input shaft 2 of described the second master gear 5 one sides, be provided with right back-up ring 9, on described right back-up ring 9, be fixedly installed with the second master gear 5 cooperatively interacts and have a magnetic clutch 10, on described driven shaft 3, be provided with the first driven gear 11 and the second driven gear 12, on the casing 1 between described the first driven gear 11 and the first master gear 4, be provided with transition axis 13, on described transition axis 13, be provided with transition gear 14, described transition gear 14 all engages with the first master gear 4 and the first driven gear 11, described the second driven gear 12 and the second master gear 5 are intermeshing.
The left magnetic clutch 8 of above-mentioned electric automobile gear-box is switched on and when right magnetic clutch 10 no electric circuit, left magnetic clutch 8 and the first master gear 4 adhesives, the first master gear 4 rotates with input shaft 2, and the first master gear 4 drives the first driven gear 11 to rotate by excessive gear 14, completes power output; In the time that needs are shifted gears, left magnetic clutch 8 power-off and right magnetic clutch 10 is switched on, the first master gear 4 is not worked, right magnetic clutch 10 and the second master gear 5 adhesives, the second master gear 5 rotates with input shaft 2, and the second master gear 5 drives the second driven gear 12 to rotate, and completes power output; Now high and low shift has been shifted gears.
When above-mentioned electric automobile gear-box reverse gear gearshift, start left magnetic clutch 8, synchronizer 6 simultaneously, drive motor reversion, under the effect of synchronizer 6, transition gear 14, the first master gear 4 and the first driven gear 11 keep engagement always, need in the time that reverse gear is shifted gears, the first master gear 4 not separated with the first driven gear 11, reduce the noise of reverse gear gearshift, ensure driver's driving comfort.
