Abstract
The utility model discloses a gearbox of an electric vehicle. The gearbox comprises a box body, wherein an input shaft, a driven shaft and a differential assembly are arranged in the box body; at least two groups of power devices are arranged on the input shaft; each group of the power device comprises an electromagnetic clutch fixedly connected with the input shaft; a driving gear used with the electromagnetic clutch in a matched manner is arranged near to each electromagnetic clutch; the input shaft is sleeved with the driving gears; the driving gears circumferentially rotate with the input shaft and axially and fixedly connected with the input shaft; driven gears corresponding to the driving gears are fixedly arranged on the driven shaft and meshed with the driving gears; and an output gear is also arranged on the driven shaft and meshed with a bull gear in the differential assembly. The operation of the gears is controlled through the electromagnetic clutches, the corresponding electromagnetic clutches are powered on according to the actual demands, other electromagnetic clutches fail to work due to power failure, the energized electromagnetic clutches are sucked with the corresponding driving gears, and the driving gears are driven to rotate, so as to output power.
Description
Technical field
The utility model relates to the electric automobile gear-box body, and particularly a kind of gear that automaticallyes switch is realized the gearbox of gear shift.
Background technique
The traditional electric automobile casing mostly is fixedly gear ratio gear-box of single motor driving, the performance of gear-box output does not reach optimization, can not satisfy in the time of need being in high rotary speed working, there are shortcomings such as starting current is big, expense electricity, grade ability difference, entire mechanism just can not power saving like this, and the continuation of the journey mileage is short; Can not discharge when needing the output high pulling torque, whole electric motor car grade ability poor (being that electric motor car is unable), the sense of superiority of not driving, main is to make rational use of resources, energy waste is big.
Summary of the invention
The utility model has overcome above-mentioned the deficiencies in the prior art, and a kind of driving mechanism of having optimized is provided, power saving, and the continuation of the journey mileage is long, and grade ability is strong, has reduced the gearbox of energy waste.
The technical solution of the utility model is achieved in that
A kind of electric automobile gear-box, comprise casing, in casing, be provided with input shaft, driven shaft and differential assembly, on input shaft, be provided with at least two group power plant, every group of power plant include a magnetic clutch of fixedlying connected with input shaft, be equipped with a master gear that is mated use on each magnetic clutch side, described master gear is socketed on the input shaft, and master gear and input shaft circumferentially rotate, axial restraint connects, on driven shaft, be installed with and the corresponding driven gear of master gear, described driven gear and gear, on driven shaft, also be provided with output gear, the gearwheel engagement in described output gear and the differential assembly.
For the protection power plant, prevent that master gear from moving axially, as preferably, adopt back-up ring to be separated by between per two groups of power plant, back-up ring and input shaft are fastenedly connected, and magnetic clutch is fixed on the back-up ring.
Adopted the principle of the present utility model and the beneficial effect of technique scheme to be:
The utility model adopts the work of magnetic clutch control gear, the quantity of magnetic clutch and gear can be set according to actual needs, and each group master gear is all different with the speed ratio of driven gear, when magnetic clutch is not worked, each group gear is not all worked yet, just driven relatively not stressing; When where needs organize master gear and driven gear engagement, to corresponding magnetic clutch energising, and other magnetic clutch outages are not worked, the corresponding master gear of magnetic clutch adhesive after the energising, the drive master gear rotates, master gear drives the driven gear that is mated and rotates, and realizes power output.
So making just can provide high rotating speed when needing high rotating speed, just can provide high pulling torque when needing high pulling torque, and whole electric motor car gear has just reached optimization, power saving continuation of the journey mileage is long, grade ability is strong, has most importantly reduced energy waste, has promoted the development of whole green energy cause.
Description of drawings
Fig. 1 is the structural representation of gearbox among the utility model embodiment.
Embodiment
Embodiment of the present utility model is as follows:
Embodiment: a kind of electric automobile gear-box, as shown in Figure 1, comprise casing 1, in casing 1, be provided with input shaft 2, driven shaft 3 and differential assembly are provided with three groups of power plant on input shaft 2, every group of power plant include a magnetic clutch of fixedlying connected with input shaft 2, be equipped with a master gear that is mated use on each magnetic clutch side, adopt back-up ring 15 to be separated by between per two groups of power plant; Back-up ring 15 is fixed on the input shaft, the i.e. magnetic clutch 1 that on input shaft 2, is provided with, magnetic clutch 2 10 is separately fixed on each self-corresponding back-up ring 15 with magnetic clutch 3 11, be equipped with in the middle of the magnetic clutch and respectively organize driving gear, be the magnetic clutch one 9 other master gears 1 that are provided with, the magnetic clutch 2 10 other master gears 27 that are provided with, the magnetic clutch 3 11 other master gears 38 that are provided with, described master gear 1, master gear 27, master gear 38 is socketed on the input shaft 2, and master gear 1, master gear 27, master gear 38 circumferentially rotates with input shaft 2, axial restraint connects, on driven shaft 3, be installed with respectively and master gear 1, master gear 27, the driven gear 1 of master gear 38 corresponding engagements, driven gear 2 13, driven gear 3 14, on driven shaft 3, also be provided with output gear 4, gearwheel 5 engagements in described output gear 4 and the differential assembly.
The utility model is controlled three groups of gears respectively by three groups of different magnetic clutchs, when all the other two groups of one group of whens work or not and are in driven state, has realized the three-gear gear shifting mechanism of entire mechanism like this.
Working procedure of the present utility model is as follows:
1, when the actuating coil of magnetic clutch 1 is switched on, master gear 1 and magnetic clutch one 9 adhesives, master gear 1 rotates with input shaft 2, and finishes the output of whole driving mechanism for driven gear 1 transmission of power, promptly realizes one grade;
2, when the actuating coil of magnetic clutch 2 10 is switched on, master gear 27 and magnetic clutch 2 10 adhesives, master gear 27 rotates with input shaft 2, and finishes the output of whole driving mechanism for driven gear 2 13 transmission of power, promptly realizes second gear;
3, when the actuating coil of magnetic clutch 3 11 is switched on, master gear 38 and magnetic clutch 3 11 adhesives, master gear 38 rotates with input shaft 2, and gives the output of finishing whole driving mechanism with driven gear 3 14 with transmission of power, promptly realizes third gear;
4, when input shaft 2 counter-rotatings, when being fixed on arbitrary magnetic clutch (generally getting that big group of the gear ratio) energising on the input shaft 2, corresponding master gear and magnetic clutch adhesive drive the output that driven gear is finished whole driving mechanism, promptly realize reverse gear.
