Abstract
The axle of a high-power hub-type electric machine of high-mechanic, there is a supporting member inside of axle, and it is characterized in that described axle is a minor axis, minor axis is not directly connected with car body.The weight of a car body axle is delivered on the supporting member at hub-type electric machine center, transmitted on two bearings of motor by supporting member again, carried power is delivered on the rotor of hub-type electric machine by bearing again, finally be delivered to ground by the tire that rotor is installed, thus arriving the airborne heavy object of increasing hub-type electric, the outlet of hub-type electric machine is then drawn by the edge of axle.
Description
Technical field
The utility model relates to a kind of axle of hub-type electric machine, especially can be used in the powerful hub-type electric machine of production high-mechanic.
Background technique
At present, along with country is to the support energetically of new energy car, various electric motor car arises at the historic moment, as: electric motor car with two wheels, two-wheeled electric motorcycle and four-wheel electric motor car etc., and these four-wheel electric motor car great majority are all carry out transforming on the framework of original automobile producing, as: pure electric vehicle, oil and electricity hybrid vehicle etc., they are all be sent on wheel hub by gear-driven mode by the energy of motor or fuel engine, drive tyre rotation by wheel hub, make automobile or electric car running movement.
The production of China's electric motor car with two wheels and popularity rate are very high, hub-type electric machine technology is widely used, and due to the thin center of the less inwall of shaft diameter of hub-type electric machine empty, for the stator coil power line of motor and signaling line are drawn outside motor, therefore, the bearing capacity smaller power of hub-type electric machine is lower, cannot be applied on the large four-wheel electric motor car of general load-bearing requirements, only practical and two-wheeled, in three-wheel and small four-wheel electric motor car, so, the hub-type electric machine studying a kind of bearing capacity high-power also large is needed to come for four-wheel electric motor car, and if if hub-type electric machine can be applied on four-wheel electric motor car, the while that then the weight of four-wheel electric motor car just can alleviating, the space of car body also can be strengthened, thus the quantity that can increase the battery of electric motor car is to increase the operating range of electric motor car.Invent a kind of high-mechanic powerful hub-type electric machine for four-wheel electric motor car being a kind of inexorable trend, but the axle of hub-type electric machine improves with regard to needs, this practical invention technology is developed for this situation.
Summary of the invention
In order to overcome the deficiency of background technique, the utility model provides the axle of the high-power hub-type electric machine of a kind of high-mechanic, is that the axle for solving traditional hub-type electric machine cannot produce the large problem carrying high power motor.
The technological scheme that the utility model adopts is: the extraction power line of traditional wheel hub electric motor and signaling line are drawn by the central position of axle, change into through being drawn by the inwall of axle, there is a supporting member corresponding with stator iron core center the inside of axle on the split of stator iron core, this supporting member center is processed as the circular hole of band key, circular hole is connected with car body by another root garden axle, and the outlet of its stator coil and signaling line is then passed through to hole on axle and extracted realization by the inwall of axle.
The axle of a hub-type electric machine, there is a supporting member inside of axle, it is characterized in that described axle is a minor axis, minor axis is not directly connected with car body, and two large diameter bearings are installed at the two ends of axle, installs stator iron core near outboard bearing place, wire outlet hole is had between stator iron core and inboard bearing, power line and signaling line are drawn by the inwall of minor axis, and have a supporting member be connected as a single entity with axle in the inside of axle, there is the hole of a band keyway at the center of supporting member.
The beneficial effect of model utility is: use the technology can the powerful wheel hub electric motor of production high-mechanic, this wheel hub electric motor can be widely used on four-wheel electric motor car, simultaneously, condition is created for changing automobile into electric motor car, reduce gear drive to alleviate the weight of car body, vacating space installs the quantity of power supply to increase, enable electric motor car travel longer distance.
Accompanying drawing explanation
Fig. 1 is the generalized section of current hub-type electric machine central shaft, and in figure, 1 and 4 is bearings mounted position, and 2 is the position of installing stator iron core, and 3 is the threading hole of stator coil, and 5 is the installation screw thread be connected with car body, and 6 is stator coil outlet.
Fig. 2 is the generalized section of hub-type electric machine central shaft of the present invention, and in figure, 1 is the position of installing outboard bearing, and 2 is the position of installing stator iron core, 3 is stator coil threading hole, 4 for installing the position of inboard bearing, and 5 is the center hole be connected with car body, and 6 is stator coil outlet; 7 is the supporting member be connected as a single entity with axle.
Embodiment:
The specific implementation method of the utility model technology is as follows:
1. the internal diameter of stator iron core is processed as the hole of 0.5mm larger than bearing bore diameter, and processes a keyway;
2. process a minor axis, axle is made up of five parts;
3. to be processed as external diameter identical with the internal diameter of bearing in the position (1) of axle, and width is also identical with the width of bearing, and implement drive fit and install, the axle core of its correspondence is processed as hollow, and wall thickness is greater than 10mm;
4. to be processed as external diameter identical with the internal diameter of stator iron core in the position (2) of axle, and process a keyway, axle and stator iron core carry out drive fit installation by key, and its width is larger than stator iron core width;
5. the position (3) of axle is processed as the garden that external diameter is greater than stator iron core internal diameter 1mm, and width is greater than 10mm, processes six holes along garden circumferential portion, and pass for lead-in wire, the axle core of its correspondence is processed as hollow, and wall thickness is greater than 10mm;
6. to be processed as external diameter identical with the internal diameter of bearing in the position (4) of axle, and width is also identical with the width of bearing, and implement drive fit and install, the axle core of its correspondence is processed as hollow, and wall thickness is greater than 10mm;
7. the center that the position (5) of axle is axle is processed as the hole of the band keyway of 30mm.
