Abstract
The utility model relates to a new forms of energy automobile wheel hub motor, include the hollow fixed axle that links firmly with vehicle chassis, divide and establish at the wheel hub at fixed axle both ends and fix the tire at wheel hub all terminal surfaces, the fixed axle hole in be equipped with fixed axle pivoted pivot relatively, the pivot both ends with wheel hub locking is fixed, the wheel hub inboard is fixed with the rotor, the stator coil that the circular telegram produced magnetism and felt the line is installed in the fixed axle both ends periphery embedding that corresponds the rotor position. The utility model provides power to drive the new energy vehicle by two groups of motors respectively arranged in hubs at two ends of the rotating shaft, so that the structure of the motor is more compact and the power is more superior; because two wheel hubs pass through the pivot and connect, even a certain motor breaks down in the use, also can ensure that the vehicle can not appear the off tracking phenomenon to the security that the vehicle travel has been improved.
Description
Technical Field
The utility model belongs to the technical field of the motor technique and specifically relates to a new forms of energy automobile wheel hub motor.
Background
In electric vehicles, for example, new energy vehicles all adopt a hub motor technology, and a power device, a transmission device and a braking device are integrally installed in a hub, so that the mechanical transmission of the electric vehicle is greatly simplified.
Traditional transmission structure in current new energy automobile adopts to set up the wheel hub motor in single wheel hub usually, through the motion of transmission shaft drive vehicle, but in case this motor breaks down, can lead to the vehicle off tracking to appear and even flame out and can't travel.
Disclosure of Invention
The to-be-solved technical problem of the utility model is: in order to overcome the deficiency among the prior art, the utility model provides a compact structure, effectively ensure new forms of energy automobile wheel hub motor that the vehicle normally traveles.
The utility model provides a technical scheme that its technical problem adopted is: the utility model provides a new forms of energy automobile wheel hub motor, includes the hollow fixed axle that links firmly with vehicle chassis, divide and establish at the wheel hub at fixed axle both ends and fix the tire at wheel hub week terminal surface, the fixed axle hole in be equipped with relative fixed axle pivoted pivot, the pivot both ends with wheel hub locks fixedly, the wheel hub inboard is fixed with the rotor, the stator coil of circular telegram production magnetism sense line is installed in the fixed axle both ends periphery embedding that corresponds the rotor position.
Specifically, a rolling bearing is arranged between the two ends of the rotating shaft and the inner hole of the fixed shaft, and the end part of the rotating shaft is connected with a locking nut for pressing the side surface of the rolling bearing.
Furthermore, the wheel hub is fixedly connected with the end face of the rotating shaft through bolts uniformly distributed in the circumferential direction.
The utility model has the advantages that: the utility model provides power to drive the new energy vehicle by two groups of motors respectively arranged in hubs at two ends of the rotating shaft, so that the structure of the motor is more compact and the power is more superior; because two wheel hubs pass through the pivot and connect, even a certain motor breaks down in the use, also can ensure that the vehicle can not appear the off tracking phenomenon to the security that the vehicle travel has been improved.
Drawings
The present invention will be further described with reference to the accompanying drawings and embodiments.
Fig. 1 is a schematic structural diagram of the present invention.
In the figure: 1. the novel hub comprises a fixed shaft, 2. a rotating shaft, 3. a tire, 4. a hub, 5. a rotor, 6. a stator coil, 7. a locking nut and 8. a rolling bearing.
Detailed Description
The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic drawings and illustrate the basic structure of the present invention only in a schematic manner, and thus show only the components related to the present invention.
Fig. 1 shows a new energy automobile hub motor, which comprises a hollow fixed shaft 1 fixedly connected with a vehicle chassis, wheel hubs 4 respectively arranged at two ends of the fixed shaft 1, and tires 3 fixedly arranged on circumferential end faces of the wheel hubs 4.
The inner hole of the fixed shaft 1 is internally provided with a rotating shaft 2 which can rotate relative to the fixed shaft 1, a rolling bearing 8 is arranged between the two ends of the rotating shaft 2 and the inner hole of the fixed shaft 1, and the end part of the rotating shaft 2 is in threaded connection with a locking nut 7 which compresses the side surface of the rolling bearing 8.
The two ends of the rotating shaft 2 are locked and fixed with the hub 4 through bolts uniformly distributed in the circumferential direction, a rotor 5 made of a permanent magnet is fixed on the inner side of the hub 4, and stator coils 6 which are electrified to generate magnetic induction lines are embedded and installed on the peripheries of the two ends of the fixing shaft 1 corresponding to the rotor 5. After the stator coil 6 is electrified to generate magnetic induction lines, the magnetic induction lines and the rotor 5 form magnetic field cutting to realize relative motion between the rotor 5 and the stator coil 6, and the rotation of the rotor 5 around the stator coil 6 drives the hub 4 and the tire 3 to rotate.
The utility model provides power to drive the new energy vehicle by installing the motor composed of the rotor 5 and the stator coil 6 in the wheel hubs 4 at the two ends of the fixed shaft 1 respectively, so that the motor structure is more compact and the power is more superior; because two wheel hubs 4 are connected through pivot 2, even a certain motor breaks down in the use, also can ensure that the off tracking phenomenon can not appear in the vehicle to the security that the vehicle travel has been improved.
In light of the foregoing, it will be apparent to those skilled in the art from this disclosure that various changes and modifications can be made without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
