Electric vehicle hub motor combining external rotation type and internal rotation type

Abstract

The invention relates to an electric vehicle hub motor combining an external rotation type and an internal rotation type, which comprises a steel ring and a hub sleeving the steel ring, wherein a motor left cover is covered on the left end port of the steel ring; a right end opening of the steel ring is covered with a right motor cover; a motor shaft is arranged in the center of the steel ring; the left end of the motor shaft penetrates out of the motor left cover, and the right end of the motor shaft penetrates out of the motor right cover; a main motor stator assembly matched with the motor shaft is arranged in the left part of the steel ring; the main motor stator assembly is connected with an electric wire, and the electric wire penetrates out to the outside; a generator stator assembly fixed with the main motor stator assembly is arranged on the right side of the main motor stator assembly; and a generator rotor matched with the motor shaft is arranged in the generator stator assembly. According to the electric vehicle hub motor combining the external rotation type and the internal rotation type, the battery of the electric vehicle can be continuously charged when the electric vehicle hub motor is used, the electric quantity of the ultra-long mileage can be met, the trouble that the electric vehicle needs to be charged frequently is avoided, and meanwhile the energy-saving effect is achieved.

Description

technical field [0001] The invention relates to an electric wheel hub motor, in particular to an electric wheel hub motor combining an external rotation type and an internal rotation type. Background technique [0002] The wheel hub motor is a device that combines the wheel hub and the motor. It can drive the wheel hub to rotate through the motor as the power to drive the electric vehicle. At present, a large number of electric vehicles used and sold on the market use single-magnetic and double-magnetic power. Motors, these power motors cannot really realize the function of charging the battery of the electric vehicle, and the battery needs to be charged frequently before the electric vehicle can be used again. Most of the mileage of the electric vehicle depends on the size of the battery capacity. Going further, the battery capacity has been increased from 48V12AH to 100AH. Although this solves the mileage problem of electric vehicles, the safety of the battery is still in ...

[0002] The wheel hub motor is a device that combines the wheel hub and the motor. It can drive the wheel hub to rotate through the motor as the power to drive the electric vehicle. At present, a large number of electric vehicles used and sold on the market use single-magnetic and double-magnetic power. Motors, these power motors cannot really realize the function of charging the battery of the electric vehicle, and the battery needs to be charged frequently before the electric vehicle can be used again. Most of the mileage of the electric vehicle depends on the size of the battery capacity. Going further, the battery capacity has been increased from 48V12AH to 100AH. Although this solves the mileage problem of electric vehicles, the safety of the battery is still in danger. At present, the most commonly used aluminum-acid batteries and lithium batteries are on the market. The cycle life of lead-acid batteries is short. It is extremely polluting to the air environment. Lithium batteries have a long cycle life and are more environmentally friendly than lead-acid batteries when manufactured. However, the danger of explosion during charging has always been in people's minds. Therefore, in order to be able to strictly supervise and supervise the charging and parking of electric vehicle batteries , the country needs to consume a lot of manpower and material resources, and in the process of using electric vehicles, if an individual needs to change a set of large-capacity lead-acid batteries, it will cost thousands of yuan, and it will cost several thousand yuan to replace a set of large-capacity lithium batteries. , the replacement cost is extremely high, and it is easy to cause economic burden on electric vehicle users
