[0002] With the rapid development of new energy vehicles, the performance of new energy vehicle axles, as a key component, directly affects the overall operation of the vehicle. In actual use, axles often face complex environments, and dust and water can easily penetrate into the axle, causing damage to the transmission components, motors, etc., and reducing the service life and reliability of the axle.

[0003] When a car is driving, if there is standing water on the road or when driving in rain or snow, a large amount of water will accumulate on the brake disc, which will affect the braking effect of the brakes and bring certain dangers to the vehicle. In addition, during the braking process, the brake disc and brake caliper use high-pressure friction to stop the wheels from rotating, and a large amount of heat will be generated during the friction process. The rapid increase in heat will cause a decrease in braking performance.

[0004] Therefore, there is an urgent need for a dustproof and waterproof new energy vehicle axle with high heat dissipation. Utility Model Content

[0008] The brake disc passes through the middle of both ends of the axle body. The brake disc is rotatably connected to the axle body and fixedly connected to the wheel. A heat dissipation component is provided on the side of the brake disc away from the axle body, and a protective component is provided on the side of the axle body.

[0009] The protective assembly includes a protective shell, the inner bottom wall of which abuts against the side end of the axle body, and the protective shell is threadedly connected to the other side of the brake disc.

[0010] The heat dissipation component includes a flow guide groove, and multiple water inlets are evenly distributed around the outer circumference of the brake disc. The flow guide groove is located inside the brake disc, and an annular groove is provided at the center of the brake disc. The brake disc has a water outlet at the annular groove, and the water inlets and the annular groove are connected through the flow guide groove.

[0025] 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.

[0026] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] The specific implementation method is as follows:

[0028] like Figures 1-5 As shown; this utility model discloses a dustproof and waterproof new energy vehicle axle, including an axle body 1,

[0029] Brake disc 2, both ends of axle body 1 pass through the middle of brake disc 2, brake disc 2 is rotatably connected to axle body 1, brake disc 2 is fixedly connected to wheel 4, a heat dissipation component is provided on the side of brake disc 2 away from axle body 3, and a protective component is provided on axle body side 3.

[0030] The protective assembly includes a protective shell 5, the inner bottom wall of which abuts against the side end 3 of the axle body, and the protective shell 5 is connected to the other side of the brake disc 2 by a thread.

[0031] The heat dissipation component includes a flow guide groove 8, and multiple water inlets 7 are evenly distributed around the outer circumference of the brake disc 2. The flow guide groove 8 is located inside the brake disc 2, and an annular groove 9 is provided at the center of the brake disc 2. The brake disc 2 is provided with a water outlet 10 at the annular groove 9. The water inlets 7 and the annular groove 9 are connected through the flow guide groove 8.

[0032] This utility model provides a protective component and a heat dissipation component on both sides of the brake disc 2. The inner bottom wall of the protective shell 5 in the protective component abuts against the side end 3 of the axle body and is connected to the brake disc 2 by threads. This tight connection provides a physical protective barrier for the axle body 1, effectively preventing external dust, sand and other foreign objects from directly impacting the axle body 1, reducing wear and damage caused by external impacts, and extending the service life of the axle body 1. At the same time, it forms a protective seal for the side end 3 of the axle body, preventing moisture from causing corrosion of the side end 3 of the axle body, and improving the waterproof and dustproof effect.

[0033] Secondly, in the heat dissipation component, the brake disc 2 is provided with a mesh guide groove 8, and the water inlet 7 and the water outlet 10 are connected through the guide groove 8 to form an effective heat dissipation channel. When the car is in motion, if there is water on the road or when driving in rain or snow, water droplets flow in from the water inlet 7 and, when passing through the mesh guide groove 8, can fully contact the brake disc 2 and carry away the large amount of heat generated by the brake disc 2 during braking.

[0034] In this embodiment, a sealing ring 6 is installed between the protective shell 5 and the brake disc 2.

[0035] The sealing ring 6 provided between the protective shell 5 and the brake disc 2 of this utility model further enhances the sealing performance of the connection. During vehicle operation, whether facing splashed mud and water or fine dust particles, the sealing ring 6 can prevent them from entering the axle through the connection gap between the protective shell 5 and the brake disc 2, preventing dust, water, etc. from intruding and causing corrosion, short circuits, and other damage to the precision components inside the axle, ensuring the normal operation of the internal components of the axle, and improving the reliability and stability of the axle.

[0036] In this embodiment, the guide channel 8 has a mesh structure.

[0037] This utility model features a mesh-like guide channel 8. Compared to the traditional single heat dissipation channel, the mesh-like guide channel 8 greatly increases the contact area between the coolant and the brake disc 2, improves the heat exchange efficiency, enables the brake disc 2 to cool down quickly, prevents the brake disc 2 from overheating and causing a decrease in braking performance, and ensures the safety and reliability of the vehicle braking system.

[0038] In this embodiment, the first intersection of the mesh of the guide channel 8 is a polygon.

[0039] The first intersection of the mesh in the guide channel 8 of this utility model is a polygon. This special structural design helps to optimize the flow path of the coolant in the guide channel 8. The polygon intersection can make the coolant form more complex turbulence during the flow process, further increasing the heat exchange effect between the coolant and the brake disc 2 and improving the heat dissipation efficiency.

[0040] In this embodiment, a waterproof layer is coated on the outside of the axle body 1, and the waterproof layer is a polyurethane waterproof coating.

[0041] The waterproof layer coated on the outer side of the axle body 1 of this utility model adds an extra layer of waterproof protection to the axle body 1. Even when driving on flooded roads or encountering severe weather, the waterproof layer can effectively prevent water from penetrating into the interior of the axle body 1, avoiding rust and damage caused by long-term contact with water, and further improving the waterproof performance and durability of the axle. The polyurethane waterproof coating is a high-molecular synthetic material with good elasticity, water resistance and weather resistance. It can form a tough waterproof membrane on the axle surface, which can adapt to the deformation of the axle under different working conditions, while resisting the erosion of ultraviolet rays, rainwater and chemicals. The polyurethane waterproof coating also has good wear resistance, which can protect the axle surface from stone impact and wear.

[0042] In this embodiment, a water outlet 11 is provided at the water outlet 10 and is fixedly connected to the brake disc 2. The water outlet 11 is arranged along the bridge body and is slidably connected to the axle body 1.

[0043] In this embodiment, a slider is fixed on the outer wall of the water outlet pipe 11, and protrusions are provided on both sides of the slider. A slide is provided around the axle body 1, and grooves that cooperate with the protrusions are provided on both sides of the slide, so that the brake disc 2 can rotate to drive the water outlet pipe 11 to slide around the axle body 1 (not shown in the figure).

[0044] This invention uses the outlet pipe 11 to carry hot water away from the brake disc 2 and discharge it at a position away from the brake disc 2. This prevents the hot water that has absorbed heat from flowing out from the inlet 7 and re-entering the guide channel 8 because it is too close to the brake disc 2. This ensures that only fresh water enters the guide channel 8, thereby improving the heat exchange efficiency.

[0045] In this embodiment, a plurality of through holes 12 are evenly provided on the water outlet pipe 11.

[0046] This utility model provides through holes 12 to rinse the surface of the axle and prevent dust accumulation on the axle surface.

[0047] The working principle of this utility model is a dustproof and waterproof new energy vehicle axle. The brake discs 2 at both ends of the axle body 1 are connected to the wheels 4 to transmit power. The protective shell 5 in the protective component is threadedly connected to the brake disc 2 and forms a physical barrier with the sealing ring 6. The waterproof layer on the outside of the axle body 1 further isolates external dust and water. During the braking process of the vehicle, when there is water on the road or when driving in rain or snow, water droplets flow in from the inlet 7. When passing through the mesh guide groove 8, they can fully contact the brake disc 2 and carry away the large amount of heat generated by the brake disc 2 during the braking process. The heat flows out with the water from the outlet 10 at the ring groove 9 through the outlet pipe 11, thereby achieving efficient dustproof and waterproof and heat dissipation, and ensuring the stable operation of the axle.
