Abstract
The utility model relates to the field of a vehicle and provides a driving system of a motor. The driving system comprises a motor, a drive shaft and a drive axle, wherein the motor is a low-speed large-torque drive motor, one end of the drive shaft is connected with the motor, and the other end of the drive shaft is connected with the drive axle which is connected with a driving wheel in a matching way. According to the driving system of the motor, the low-speed large-torque drive motor is adopted, a two-stage reducer is changed into a single-stage reducer, so that the total mass of the driving system can be effectively reduced, and the complete vehicle kerb mass can be reduced; and the complete vehicle kerb mass is reduced, so that the driving range of the vehicle can be increased, and the waste of resources can be reduced.
Description
Technical field
The utility model relates to automotive field, more particularly, relates to a kind of electric motor drive system.
Background technology
Automobile has become the indispensable vehicle in people's modern life, yet along with modern economy development and modernization construction constantly advance, the wasting of resources also is on the rise, how to utilize to maximal efficiency limited resources, reducing unnecessary waste, is the key subjects that current social needs is faced.
At present, the technical scheme that adopts of general electronlmobil drive form is electrical motor+retarder+axle drive shaft+drive axle.This technical scheme is the most common, but the negative effect that this scheme but brings system's total mass to increase has increased curb mass accordingly, has reduced the vehicle continual mileage to a certain extent, thereby has wasted resource to a certain extent.
The utility model content
The technical problems to be solved in the utility model is, at the above-mentioned defective of prior art, provides a kind of and can effectively reduce system's total mass, thus the electric motor drive system of the minimizing wasting of resources.
The technical scheme that its technical matters that solves the utility model adopts is: construct a kind of electric motor drive system, comprise electrical motor, axle drive shaft and drive axle, described electrical motor is the low-speed big drive motor, one end of described axle drive shaft connects described electrical motor, the other end of described axle drive shaft connects described drive axle, and described drive axle is connected with the driving wheel.
Further, described drive axle comprises single reduction gear, described single reduction gear and the coupling of described axle drive shaft.
Further, described drive axle shell is connected by bolt with described drive shaft shell.
Further, described motor casing is provided with cold chamber.
Further, described cold chamber lower end is provided with the refrigerant fluid entrance, and described cold chamber upper end is provided with cooling liquid outlet.
Preferably, described refrigerant fluid is water.
A kind of electric motor drive system that the utility model provides, adopt novel low-speed big drive motor, change the dual-ratio reduction device into single reduction gear, effectively reduce the drive system total mass, thereby complete vehicle curb weight is decreased, because the reduction of Vehicle preparation quality, the continual mileage of vehicle increases to some extent, thereby has reduced the waste of resource.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below, apparently, accompanying drawing in describing below only is embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the structural representation of a kind of electric motor drive system of the utility model.
The specific embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that obtains under the creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1, in first embodiment of a kind of electric motor drive system of the present utility model, electrical motor 3 drive systems comprise electrical motor 3, axle drive shaft 2 and drive axle 1, one end of axle drive shaft 2 connects electrical motor 3, the other end of axle drive shaft 2 connects drive axle 1, drive axle 1 comprises single reduction gear, single reduction gear and axle drive shaft 2 couplings, and drive axle 1 is connected with driving wheel 4; This electrical motor 3 drive systems adopt single reduction gear to replace the dual-ratio reduction device, effectively reduce the quality of drive system, have increased the continual mileage of vehicle.
In a kind of electric motor drive system of the present utility model, electrical motor 3 is the low-speed big drive motor, this motor is the output characteristic that changes frequency control motor by the adjustment of the change of power supply mode and electromagnetic structure, be converted in the process of mechanical energy at electric energy, do not need mechanical deceleration device can satisfy the operation characteristic of this type of low-speed big equipment yet, improved the equipment reliability of operation, remove all inconvenience of plant maintenance from, reduced taking up room and total quality, having reduced energy resource consumption of equipment simultaneously.
Among a kind of electric motor drive system embodiment of the present utility model, drive axle 1 shell is connected by bolt with axle drive shaft 2 shells, is convenient to dismounting, convenient for maintaining; Certainly drive axle 1 and axle drive shaft 2 shells are not limited to this connection mode, other suitable methods also can, even also can adopt a shell, the shape of this shell is similar with the connect together shape of the integral body that forms of drive axle 1 and axle drive shaft 2, this shell is divided into upper casing and lower casing, and upper casing is connected by bolt with lower casing.
Among a kind of electric motor drive system embodiment of the present utility model, as shown in Figure 1, electrical motor 3 shells are provided with cold chamber 5, cold chamber 5 lower ends are provided with refrigerant fluid entrance 6, cold chamber 5 upper ends are provided with cooling liquid outlet 7, refrigerant fluid charges into from the refrigerant fluid entrance 6 of lower end, flow out from the cooling liquid outlet 7 of cold chamber 5 upper ends, the heat that produces during in time with electrical motor 3 work is replaced away, prevent that electrical motor 3 is overheated, can effectively prolong 3 service lifes of electrical motor like this, the heat taken out of of refrigerant fluid reusable edible has also been saved the energy simultaneously.Because it is bigger that specific heat of water holds, the heat that the water of same volume is taken out of is also more, simultaneously because water resource is honest and clean, sufficient and be easy to get, so refrigerant fluid is generally selected water for use.
The above only is preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
