Abstract
An electric vehicle wheel hub with sealing drain holes comprises a rotor casing, a fly wheel, a bearing, sealing parts, a wheel hub casing and the drain holes and is characterized in that the bearing is connected to the central position of the rotor casing, the fly wheel is fixedly connected to one end of the bearing, the rotor casing and the wheel hub casing coaxial with the rotor casing are fixedly connected, and a plurality of drain holes are evenly arranged on the circumference of the rotor casing and are in matched connection with the sealing part. The drain holes are threaded holes. The sealing parts are screws. The improvement of the electric vehicle wheel hub on the original basis is small, the electric vehicle wheel hub has outstanding practical applicability and creativeness, the sealing parts are dismantled at regular periods to discharge water vapor in the rotor casing, lubricating oil can be added through the drain holes, the service life of an electric vehicle is effectively prolonged, and maintenance of the electric vehicle is further facilitated.
Description
Technical field
The utility model relates to a kind of electric vehicle hub, relates in particular to a kind of electric vehicle hub with the sealing drain gutter.
Background technology
electric vehicle hub is metalwork at present, the structure that porose axle coordinates on the center of circle of wheel hub, axle connects motor stator, when the actual use of battery-driven car, due to the electrical power heating, air in rotor case will flow owing to expanding with heat and contract with cold, moisture in so a large amount of damp air condenses in rotor case, rotation due to wheel hub, under the effect of centnifugal force, water is gathered in the edge in rotor case, not only corrode rotor case, also be very easy to cause the copper binding wire short circuit on stator, cause stator to be burnt, especially the Hall control element in rotor case is very easy to be burnt out by the rainwater short circuit, need to change the controller without Hall element, cause motor rotation just to have some setbacks, hole on rotating shaft and wheel hub is engaged under long term wear, its gap also can be increasing, in the rainy day, rainwater is easy in rotating shaft flows into rotor case, cause stator to damage, because rotor case is metalwork, the leak tightness of its hole axle is difficult to avoid entering of water in air steam, therefore, the steam that reduces in the battery-driven car rotor is the prolongation battery-driven car important channel in service life.
Summary of the invention
The purpose of this utility model has been to provide a kind of electric vehicle hub with the sealing drain gutter, and it has steam in the wheel hub of minimizing, extends the battery-driven car advantage in service life.
The utility model is achieved like this, it comprises rotor case, flywheel, bearing, sealing member, wheel hub shell and drain gutter, the center that it is characterized in that rotor case is connected with bearing, one end of bearing is fixed with flywheel, rotor case with captive joint with its coaxial wheel hub shell, evenly distributed on the circumference of rotor case have some drain gutters, drain gutter and sealing member are connected, described drain gutter is tapped bore, and described sealing member is screw.
Technique effect of the present utility model is: the utility model improves little on the original basis, but have outstanding practicality characteristics, regularly pull down sealing member, discharge steam in rotor case, can also add lubricating oil by drain gutter, not only effectively improve battery-driven car service life, also helped the M R of battery-driven car.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structure for amplifying schematic diagram at A place in Fig. 1.
The specific embodiment
As shown in Figure 1 and Figure 2, the utility model is achieved like this, it comprises rotor case 1, flywheel 2, bearing 3, sealing member 4, wheel hub shell 5 and drain gutter 6, its constructional feature is that the center of rotor case 1 is connected with bearing 3, one end of bearing 3 is fixed with flywheel 2, rotor case 1 with captive joint with its coaxial wheel hub shell 5, evenly distributed on the circumference of rotor case 1 have some drain gutters 6, drain gutter 6 is connected with sealing member 4, described drain gutter 6 is tapped bore, and described sealing member 4 is screw; In use, due to the friction of bearing 3 with the rotor case 1 that constantly rotates, its gap is increasing, steam constantly condenses in rotor case 1, regular dismounting is fallen the sealing member 4 on drain gutter 6, starter motor, rotor case 1 is when at full speed rotation, and due to centrifugal action, the water in rotor case 1 will be thrown to the circumferential edges place, then discharge by drain gutter 6, after rotor case 1 stops, can also add lubricating oil from drain gutter 6, by sealing member 4 sealing drain gutters 6, such as drain gutter 6 is designed to tapped bore, sealing member 4 is designed to screw; By the steam of regular discharge rotor case 1, avoided the corrosion of steam to rotor, especially in the larger south of steam, adopt battery-driven car of the present utility model effectively to increase the service life, maintain very convenient.
Claims (3)
