Description

Technical Field

[0001] The present invention relates to the technical field of wheel hub motors, and in particular to a wheel hub motor with an integrated liquid cooling circulation channel. Background Art

[0002] The wheel hub motor, also known as the electric wheel, is a motor that integrates power, transmission and braking devices into the wheel hub. The working principle of the wheel hub motor is based on the law of electromagnetic induction. It drives the vehicle by directly converting electrical energy into mechanical energy for wheel rotation. The electric vehicle battery provides DC power, and the inverter converts DC power into AC power. The AC power is supplied to the stator winding, and the current is switched according to the law of three-phase AC power to generate a rotating magnetic field. When the rotating magnetic field generated by the stator winding acts on the permanent magnet or electromagnet rotor installed in the wheel hub, due to electromagnetic interaction, the rotor will rotate synchronously with the direction of the magnetic field. The rotation of the rotor directly drives the wheel to rotate, eliminating the complex transmission components such as clutches, transmissions, and differentials in traditional cars, and realizing direct power output.

[0003] At present, the liquid cooling structure of traditional hub motors is often set up independently, failing to effectively coordinate heat dissipation with the braking system and failing to fully utilize the heat distribution characteristics within the system, resulting in poor heat dissipation. At the same time, a large amount of heat energy generated during vehicle braking is usually wasted and cannot be effectively recycled, resulting in energy waste. Summary of the invention

[0004] To this end, the present invention provides a hub motor with an integrated liquid cooling circulation channel to solve the above-mentioned problems in the prior art.

[0005] In order to achieve the above object, the present invention provides the following technical solutions: According to a first aspect of the present invention, a hub motor with an integrated liquid cooling circulation channel comprises a drive motor mechanism, the drive motor mechanism comprises a mounting member, the top of the mounting member is bolted to a fixing member, the top of the fixing member is fixedly connected to a motor housing, and the inner wall of the motor housing is fixedly connected to a stator; a braking mechanism, the braking mechanism comprises a brake disc and a brake clamp, the brake clamp is arranged on the surface of the brake disc; a TEG heat energy recovery mechanism of an external electric energy storage, the TEG heat energy recovery mechanism comprises a TEG hot end, one side of the TEG hot end overlaps the surface of the brake disc, and the top of the TEG hot end is fixedly connected to the TEG cold end; an integrated liquid cooling mechanism, the integrated liquid cooling mechanism comprises a brake disc cooling chamber, the top of the brake disc cooling chamber is provided with a TEG cooling chamber, one side of the brake disc cooling chamber overlaps the side of the brake disc away from the TEG hot end, and the interior of the brake disc cooling chamber is connected to the interior of the TEG cooling chamber.

[0006] Furthermore, the driving motor mechanism further comprises a spiral flow chamber, the spiral flow chamber is arranged inside the motor housing, and a rotor is arranged inside the stator.

[0007] Furthermore, a tire mounting plate is fixedly connected to the surface of the rotor shaft, and a wheel hub is bolted to one side of the tire mounting plate.

[0008] Furthermore, a tire is provided on the surface of the wheel hub, the surface of the rotor shaft is fixedly connected to the inside of the brake disc, and one side of the mounting piece is bolted to one side of the brake clamp.

[0014] The present invention has the following advantages: through the setting of an integrated liquid cooling mechanism, the liquid cooling channels of the motor and the brake mechanism are integrated to achieve coordinated heat dissipation of the two systems. The coolant flows through the interior of the drive motor mechanism, absorbs the heat inside the motor, and then enters the surface of the brake disc to absorb the heat inside the brake disc, thereby fully utilizing the heat dissipation capacity of the coolant, improving the overall heat dissipation efficiency, and reducing the volume and cost of the heat dissipation system. At the same time, the TEG hot end is attached to the surface of the brake disc, and the coolant flows through the TEG cold end. The coolant is used to cool the TEG cold end, and the brake disc and the TEG hot end are heated, thereby effectively recovering the heat energy generated during the braking process and converting it into electrical energy, thereby realizing the recovery and utilization of heat energy, improving the energy utilization efficiency of the vehicle, and making it more convenient to use.
