Description

Technical Field

[0001] This utility model relates to the field of automotive wheel hub bearing technology, specifically a wheel hub bearing mechanism for new energy vehicles that can improve lubrication oil deficiency. Background Technology

[0002] Wheel bearings are a critical component of automobile wheels, their main functions being to bear weight and provide precise guidance for the rotation of the wheel hub. This requires them to withstand not only axial loads but also radial loads.

[0003] When existing wheel hub bearing mechanisms are in use, the bearing generates heat due to friction and load during operation, causing the temperature to rise. Excessive bearing temperature accelerates the oxidation and deterioration of the lubricant, reduces the bearing's lubrication performance, and leads to excessive consumption of lubricating oil, affecting the bearing's reliability and performance during use.

[0004] Therefore, this utility model proposes a wheel hub bearing mechanism for new energy vehicles that can improve lubrication oil deficiency in order to solve the above problems. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: a wheel hub bearing mechanism for new energy vehicles that can improve lubrication oil deficiency, including an outer bearing ring, a ball movably connected inside the outer bearing ring, an inner ring inside the ball, and a cooling protection mechanism.

[0006] Preferably, the cooling protection mechanism includes a mounting ring, which is fixedly connected to the inner surface of the outer ring of the bearing, and a rotating disk is rotatably connected to one side of the mounting ring at equal intervals.

[0007] Preferably, one end of the rotating disk is fixedly connected to a linkage disk, and an arc-shaped protrusion is fixedly connected to the outer surface of the linkage disk, and the rotating disk is in contact with the inner ring.

[0008] Preferably, a fixing box is fixedly connected at equal intervals on one side of the mounting ring, a one-way air intake valve is fixedly connected to one side of the fixing box, and a piston plate is slidably connected inside the fixing box.

[0009] Preferably, a pressure rod is fixedly connected to one side of the piston plate, one side of the pressure rod is arc-shaped, and a return spring is fixedly connected between the pressure rod and the mounting ring.

[0011] Compared with the prior art, this utility model provides a wheel hub bearing mechanism for new energy vehicles that can improve lubrication oil loss, and has the following beneficial effects:

[0012] 1. By setting up a cooling and protection mechanism, when the inner ring rotates, the cooperation between the arc-shaped protrusion and the pressure rod causes the jet nozzle to continuously spray airflow and act on the outer surface of the inner ring, thereby accelerating the airflow on the outer surface of the inner ring. Accelerating the airflow can improve its heat dissipation efficiency, thereby preventing the lubricating oil from being consumed too quickly, which would affect the bearing's performance and improve its service life.

[0013] 2. The force generated by the rotation of the inner ring drives the rotating disk to rotate, thereby generating airflow to cool the inner ring. This saves the installation of an additional drive source, reduces the cost of heat dissipation, and improves the heat dissipation efficiency of the inner ring. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0023] Embodiments of this utility model

[0024] Please refer to Figures 1 to 4 As shown:

[0025] To address the problems mentioned in the technical solutions, this application provides a wheel hub bearing mechanism for new energy vehicles that can improve lubrication oil deficiency. The mechanism includes an outer bearing ring 1, a ball bearing 11 movably connected inside the outer bearing ring 1, an inner ring 12 inside the ball bearing 11, and a cooling protection mechanism.

[0026] The cooling protection mechanism includes a mounting ring 301, which is fixedly connected to the inner surface of the outer ring 1 of the bearing. A rotating disk 302 is rotatably connected to one side of the mounting ring 301 at equal intervals. A linkage disk 303 is fixedly connected to one end of the rotating disk 302. An arc-shaped protrusion 304 is fixedly connected to the outer surface of the linkage disk 303. The rotating disk 302 is in contact with the inner ring 12. A fixing box 305 is fixedly connected to one side of the mounting ring 301 at equal intervals. A one-way intake valve 306 is fixedly connected to one side of the fixing box 305. A piston is slidably connected inside the fixing box 305. A piston plate 307 has a pressure rod 308 fixedly connected to one side. One side of the pressure rod 308 is arc-shaped. A return spring 309 is fixedly connected between the pressure rod 308 and the mounting ring 301. A one-way air valve is fixedly connected to one side of the fixed box 305. A connecting pipe 310 is fixedly connected to one side of the one-way air valve. An arc-shaped hollow plate 311 is fixedly connected at equal intervals to one side of the mounting ring 301. The connecting pipe 310 is connected to the arc-shaped hollow plate 311. An air nozzle 312 is fixedly connected at equal intervals to one side of the arc-shaped hollow plate 311.

[0027] The working principle of all the content in the above embodiments is as follows:

[0028] In use, the outer shaft is installed with the inner ring 12. When the outer shaft rotates, it will simultaneously drive the inner ring 12 to rotate. Through the friction generated by the contact between the inner ring 12 and the rotating disk 302, the rotation of the inner ring 12 will drive the rotating disk 302 to rotate simultaneously. In turn, the rotation of the rotating disk 302 will drive the linkage disk 303 to rotate, which will cause the arc-shaped protrusion 304 to rotate and move closer to the pressure rod 308. This will squeeze the pressure rod 308 and drive the piston plate 307 to move towards the connecting pipe 310. This will allow the airflow of the fixed box 305 to enter the connecting pipe 310 and the arc-shaped hollow plate 311 through the one-way air outlet valve and finally be ejected from the jet nozzle 312 and flow towards the inner ring 12. When the arc-shaped protrusion 304 moves away from the pressure rod 308, under the action of the return spring 309, the piston plate 307 and the pressure rod 308 will be reset again. This will allow the external airflow to re-enter the fixed box 305 through the one-way air inlet valve 306, thus facilitating the next air blowing cleaning operation.

[0029] By setting up a cooling and protection mechanism, when the inner ring 12 rotates, the arc-shaped protrusion 304 and the pressure rod 308 cooperate to make the jet nozzle 312 continuously spray airflow and act on the outer surface of the inner ring 12, thereby accelerating the airflow on the outer surface of the inner ring 12. Accelerating the airflow can improve its heat dissipation efficiency, thereby preventing the lubricating oil from being consumed too quickly, which would affect the bearing's performance and improve its service life.

[0030] At the same time, the force generated by the rotation of the inner ring 12 drives the rotating disk 302 to rotate, thereby generating airflow to cool the inner ring 12, saving the installation of an additional drive source, reducing the cost of heat dissipation, and improving the heat dissipation efficiency of the inner ring 12.
