Abstract
The utility model discloses a differential transmission device for electric vehicles, which comprises a left and a right half shafts with two outside ends equipped with wheels, worm gears which are mutually meshed and a bevel gear differential mechanism. The bevel gear differential mechanism is arranged in a general outer shell, two ends of the bevel gear differential mechanism are connected with one end of the inner side of the left and the right half shafts, and the bevel gear differential mechanism is engaged and connected with a worm gear which is driven to rotate by an output shaft of the motor through a worm, to drive the bevel gear differential mechanism to operate. The differential transmission device decreases the size of the whole power arrangement to the full extent by employing the bevel gear differential mechanism installed in the central space of the worm gear, and effectively resolves the problem that wheel-slippage brought by two wheels generating speed difference when turning, thereby reducing wheel wear.
Description
Technical field
The utility model relates to a kind of vehicle transmission gear, particularly relates to a kind of differential driver that is used for electric vehicle.
Background technique
In the prior art, differential mechanism generally is applied on the automobile, at present, the drive unit that the built-in differential mechanism of power unit is used for small-sized electric three-wheel or four-wheel wagon does not also appear, because in small-sized electric three-wheel or the four-wheel wagon turning process, identical with automobile, the distance that the distance that inboard wheel is walked is walked than outboard wheels is short, thereby produce the speed discrepancy phenomenon of left and right two-wheeled, and produce because of the wheelslip turn inside diameter changes the phenomenon of not passing by, can cause tire to produce the problem of inordinate wear simultaneously.
The model utility content
The purpose of this utility model is to provide a kind of differential driver that can prevent the wheel-slip of electric vehicle and can reduce the electric vehicle that causes the tire inordinate wear owing to turning.
The purpose of this utility model realizes by following technological scheme: a kind of differential driver of electric vehicle, comprise outside two ends wheel-mounted left and right sides semiaxis and the worm and gear that is meshed, it is characterized in that also comprising the bevel gear box of tricks, this bevel gear box of tricks is located in the general shell, bevel gear box of tricks two ends are connected inboard one end of left and right half, and be connected by the worm wheel of motor output shaft by worm screw institute driven rotary, drive the running of bevel gear box of tricks.
The utility model is in the power plant in electric vehicle box of tricks to be set, and when electric vehicle can effectively prevent wheel-slip when turning, and reduces tire chafing; To motor, drive the running of bevel gear box of tricks by battery pack output power in the electric vehicle, travel, and solve wheel-slip problem in the electric vehicle with this powered vehicle by its output shaft.
Described bevel gear box of tricks has the differential mechanism shell outward, worm gear in the form of a ring, outboard flanges face by its circumferential end surfaces and differential mechanism shell links together, differential mechanism shell two ends are placed in respectively on the outer edge surface of semi-axle bevel gear, described bevel gear box of tricks comprises gear shaft, two bevel planet gear and two semi-axle bevel gears that are loaded on the left and right half inboard respectively that are loaded on the gear shaft two ends respectively, and described bevel planet gear and semi-axle bevel gear are meshing with each other; Described gear shaft two ends radially are loaded on this worm gear center inner ring surface along worm gear, and the gear teeth respective side of described worm gear is provided with the worm screw that is meshed with it.
The utility model worm gear is loaded on box of tricks in its center ring in the form of a ring, makes bulk be reduced to minimum, and is simple in structure, can reduce manufacture cost, makes things convenient for the layout and the installation of car load.
The two ends of described differential mechanism shell are with block bearing respectively, this block bearing the differential mechanism outer casing supporting in general shell.
Be arranged with block bearing on the described left and right half.
Compared with prior art, the utlity model has following significant effect:
1, by in the power plant in electric vehicle box of tricks being set, eliminates the phenomenon of electric vehicle wheel-slip when turning, can guarantee that vehicle effectively turns to, and reduce the wearing and tearing of tire.
2, directly drive the bevel gear box of tricks running that is installed in the worm gear center ring by motor output shaft through worm and worm gear, make bulk be reduced to minimum, simple in structure, can reduce manufacture cost, make things convenient for the layout and the installation of car load.
Description of drawings
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Fig. 1 is the utility model embodiment's a generalized section.
Embodiment
As shown in Figure 1, the utility model is used for the differential driver of electric vehicle, be wrapped in the general shell 1, it comprises the outside wheel-mounted left and right half 2 in two ends and worm gear 3 that is meshed and worm screw 4, also comprise bevel gear box of tricks 5, this bevel gear box of tricks 5 has differential mechanism shell 9, and this differential mechanism shell 9 is positioned at general shell 1 middle part.Above-mentioned worm gear 3 in the form of a ring, the outboard flanges face by its circumferential end surfaces and differential mechanism shell 9 tightens together, and with the corresponding side of worm gear 3 gear teeth worm screw 4 that is meshed with its gear teeth is housed.Above-mentioned bevel gear box of tricks 5 comprises gear shaft 6, two bevel planet gears 7 that are placed in the gear shaft two ends respectively and two are placed in a left side respectively, the semi-axle bevel gear 8 of right axle shaft 2 inboards, above-mentioned bevel planet gear 7 is meshing with each other with semi-axle bevel gear 8, said gear axle 6 two ends radially are loaded on the center inner ring surface of this worm gear 3 along worm gear 3, correspondingly, bevel gear box of tricks 5 is positioned at worm gear 3 center anchor rings, above-mentioned differential mechanism shell 9 two ends are placed in respectively on the outer edge surface of semi-axle bevel gear 8, and differential mechanism shell 9 two ends are with block bearing 10 outward respectively, and this block bearing 10 is bearing in differential mechanism shell 9 in the general shell 1.On the above-mentioned left and right half 2 also symmetry be with block bearing 11.
Motor output shaft drives worm screw 4 and rotates, driving worm gear 3 thus rotates, and make differential mechanism shell 9 along with one plays rotation, and driven gear axle 6 rotates, the bevel planet gear 7 that is loaded on the gear shaft 6 also can be along with gear shaft 6 moves together, owing to be the cone gear form shape, and bevel planet gear 7 is meshing with each other with semi-axle bevel gear 8, just make semi-axle bevel gear 8 also rotate simultaneously, and the drive wheel travels, at this moment the rotating speed of left and right wheels is identical, and bevel gear box of tricks 5 is not had an effect, and turns round with same wheel shaft as left and right wheels; When turning, inboard and outboard wheels can produce speed discrepancy, and this moment, bevel planet gear 7 just rotated according to the speed discrepancy that left and right half bevel gear 8 is occurred, compensate, thereby make the electric vehicle bend that can travel smoothly, keep wheel pure rolling on the ground, eliminate skidding.
