Abstract
The utility model discloses a transmission structure for an electric vehicle, structurally comprising an electrical machine and a wheel shaft; the electrical machine is connected with an end tooth clutch by a speed changing box to drive the wheel shaft; and the speed changing box is meshed on a shaft end gear of the end tooth clutch by the shaft end gear, and a clutch two-gear gear of the end tooth clutch is meshed on gears which respectively correspond to the wheel shaft. The high-speed end tooth clutch is added in the transmission structure for the electric vehicle, and the end tooth clutch can be preformed during high-speed rotation, so that the electrical machine can perform the gear shifting by the speed changing box after weight loading during the high-speed rotation, and can achieve the climbing capacity by means of speed reduction and torsion increase. The vacancy that the electrical machine does not have the climbing capacity can be filled, and the problem that the gear shifting can not be performed during the high-speed rotation can be solved, therefore, the transmission structure is a new milestone of the speed changing box of the electric vehicle.
Description
Technical field
The utility model relates to electric motor car, specifically a kind of drive mechanism that is used for electric motor car.
Background technology
High speed contrate-gear-type clutch is a kind of novel foundation mechanism that can when (comprising low speed, static) turns round at a high speed, carry out clutch that relies on end face and tooth to carry out transmission.Form by half-clutch device, the half-clutch device that floats.In conjunction with the time at first end face contact, rely on the frictional force transmission; When speed discrepancy, the half-clutch device that floats moves forward immediately, accomplishes the combination of tooth automatically fast, by the facing transfer torque of engagement.High speed contrate-gear-type clutch has the advantage of jaw clutch, friction clutch concurrently: simple in structure, compact, can high-speed clutch, and the course of work is steady.Can be widely used in industries such as automobile, lathe, weaving, metallurgy and to be specially adapted to need to confirm in the driving-chain of gearratio and high speed clutch.
Electric motor car can not gear shift; Not having climbing capacity, is because the drive mechanism of electric motor car directly is the driven by motor axletree, so must in the electric motor car drive mechanism, add high speed contrate-gear-type clutch; Can when running up, carry out the end tooth clutch; To satisfy motor when running up, gear box shift is passed through in the back of bearing a heavy burden, and increases to turn round with deceleration to reach climbing capacity.
The utility model content
The purpose of the utility model is the defective that exists to prior art, a kind of drive mechanism that is used for electric motor car is provided, and a difficult problem that can't shift when having filled up electric motor car and not having vacancy and the high-speed cruising of climbing capacity will be the new mileage of electric motor car gearbox.
The utility model solves the technical scheme that its technical problem adopted: a kind of drive mechanism that is used for electric motor car, and its structure comprises motor and axletree; Said motor is connected with contrate-gear-type clutch and the driving cars wheel shaft through gearbox; Said gearbox is engaged on through shaft end gear on the shaft end gear of contrate-gear-type clutch, and the clutch intermediate gear of said contrate-gear-type clutch is engaged on the corresponding gear of difference on the axletree.
A kind of drive mechanism that is used for electric motor car of the utility model is compared with prior art, has following beneficial effect:
The utility model adds high speed contrate-gear-type clutch in the electric motor car drive mechanism, can when running up, carry out the end tooth clutch, and to satisfy motor when running up, gear box shift is passed through in the back of bearing a heavy burden, and increases to turn round with deceleration to reach climbing capacity.Difficult problem that can't shift when having filled up electric motor car and not having vacancy and the high-speed cruising of climbing capacity will be the new mileage of electric motor car gearbox.
Description of drawings
Accompanying drawing is a kind of structural representation that is used for the drive mechanism of electric motor car of the utility model.
Among the figure: 1, gearbox; 2, contrate-gear-type clutch; 3, axletree.
Embodiment
Next explanation at length below with reference to Figure of description a kind of drive mechanism that is used for electric motor car of the utility model being done.
A kind of drive mechanism that is used for electric motor car, its structure comprises motor and axletree; Said motor is connected with contrate-gear-type clutch 2 and driving cars wheel shaft 3 through gearbox 1; Said gearbox is engaged on through shaft end gear on the shaft end gear of contrate-gear-type clutch, and the clutch intermediate gear of said contrate-gear-type clutch is engaged on the corresponding gear of difference on the axletree.
In the electric motor car drive mechanism, add high speed contrate-gear-type clutch, can when running up, carry out the end tooth clutch, to satisfy motor when running up, gear box shift is passed through in the back of bearing a heavy burden, and increases to turn round with deceleration to reach climbing capacity.Difficult problem that can't shift when having filled up electric motor car and not having vacancy and the high-speed cruising of climbing capacity will be the new mileage of electric motor car gearbox.
The above embodiment is a kind of of the more preferably concrete execution mode of the utility model, and common variation that those skilled in the art carries out in the utility model technical scheme scope and replacement all should be included in the protection range of the utility model.
