Problems solved by technology

Although this can meet the needs of running vehicles under normal working conditions, when the vehicle encounters special working conditions, such as climbing, snow, and muddy road conditions, obviously the load on the hub motor will increase, and the heat will increase sharply during the working process. , the existing air-cooled heat dissipation system is difficult to meet the above heat dissipation requirements, which may lead to the occurrence of burnout of the hub motor; therefore, it is necessary for those skilled in the art to improve this

Embodiment 1

[0032] see figure 1 , a rail chassis wheel hub motor, including a chassis 1 and a frame 2, the frame 2 is installed on the front and rear sides of the chassis 1, the frame 2 serves as a buffer and support function, and its hardness is adjusted according to the use of the rail chassis. The rigidity of the chassis makes it more comfortable for the matcher, and the frame 2 also has a certain shock absorption function. The suspension 3 is connected to the fixed in-wheel motor. The function of the suspension 3 is to transmit the force and torque acting between the in-wheel motor assembly 4 and the frame 2, and use the buffer to transmit the uneven road to the frame 2 or To reduce the impact force of the chassis 1 and reduce the vibration caused thereby, the suspension 3 is connected to the in-wheel motor assembly 4 and the cooling device 5, and the cooling device 5 extends to the in-wheel motor assembly 4 to reduce the temperature.

[0033]The frame 2 includes a main beam 21, an a...

Embodiment 2

[0043] The structure of the cooling device 5 is changed, and the rest is the same as the first embodiment. The cooling device 5 includes a sleeve seat 51, a shaft rod 52, a liquid inlet pipe 53 and a liquid outlet pipe 54. On both sides of the sleeve seat 51, the liquid inlet pipe 53 and the liquid outlet pipe 54 are located on the radial direction of the two sides, and the diameters of the two nozzles are the same. The liquid inlet pipe 53 is connected with the output end of the refrigeration component, and the liquid outlet pipe 54 is connected to the input end of the refrigeration assembly. When the refrigeration assembly is working, the temperature of the cooling liquid is lowered and flows into the liquid inlet pipe 53. The liquid outlet pipe 54 flows the cooling liquid that exchanges superheat, and flows into the refrigeration assembly to re-refrigerate to complete The continuous circulation of the cooling liquid achieves the function of continuously dissipating heat to t...

Embodiment 3

[0046] Change the structure of the cooling device 5, and the rest is the same as the first embodiment. On both sides, and the diameter of the nozzles of both are the same, the liquid inlet pipe 53 is connected to the output end of the refrigeration component, and the liquid outlet pipe 54 is connected to the input end of the refrigeration component. In the liquid pipe 53 and the liquid outlet pipe 54, the cooling liquid that exchanges superheat flows, and flows into the refrigeration component, and re-refrigerates to complete the continuous circulation of the cooling liquid, thereby realizing the function of continuously dissipating heat to the inside of the hub motor assembly 4. , the liquid inlet pipe 53 and the liquid outlet pipe 54 are combined with the shaft rod 52, the two ends of the cooling channel 521 are respectively connected with the liquid inlet pipe 53 and the liquid outlet pipe 54, and the structure of the sleeve seat 51 is removed, and the shaft is directly conn...

Abstract

The invention discloses a wheel hub motor for a rail chassis, which belongs to the technical field of wheel hub motors. , the suspension is connected with the wheel hub motor assembly and the cooling device, and the cooling device extends to the wheel hub motor assembly to reduce the temperature. The invention proposes a wheel hub motor for a rail chassis, which utilizes a liquid inlet pipe and a liquid outlet pipe to discharge the cooling liquid into the shaft to realize the internal cooling of the shaft. On the side, the liquid inlet pipe and the liquid outlet pipe are located in the same radial direction, and the liquid outlet pipe is connected to the input end of the refrigeration assembly. When the refrigeration assembly is working, the temperature of the cooling liquid is lowered and flows into the liquid inlet pipe, and the liquid outlet pipe flows in the exchange of superheat. The cooling liquid flows into the cooling assembly, and re-refrigerates to complete the continuous circulation of the cooling liquid, thereby realizing the function of continuously dissipating heat inside the in-wheel motor assembly.

Description

technical field [0001] The invention relates to the technical field of in-wheel motors, in particular to a rail-chassis in-wheel motor. Background technique [0002] In order to reduce energy consumption, reduce environmental pollution, and use clean energy as power, electric vehicles with zero pollution and zero emissions have attracted more and more attention. In-wheel motor-driven electric vehicles have become a research hotspot due to their simple mechanical transmission structure, high drive efficiency, and low cost. The existing electric vehicle is driven by a central motor plus a mechanical transmission, a mechanical differential, or a hub motor plus an electronic software differential. [0003] Although the mechanical differential can achieve a perfect differential speed, it can ensure that the left and right hub motors rotate at different speeds, so that the hub motors on both sides can drive at unequal distances in the form of pure rolling as much as possible, red...
