Description

Technical Field

[0001] This utility model relates to the technical field of wheel detection devices, and in particular to an anti-interference structure for wheel lubrication pipelines. Background Technology

[0002] In a wheel speed detection system, the encoder is a key component for monitoring the wheel's operating status. It is usually mounted on one side of the wheel to collect speed information in real time.

[0003] However, in traditional designs, the lubrication lines 100 for the bearings and the encoder 2 suffer from an unavoidable axial overlap in terms of installation space (e.g. Figure 4 As shown in the figure, this defect causes spatial interference between the lubrication line 100 and the encoder 2 during the assembly stage, making it difficult to install them accurately in the preset position. This not only prolongs the assembly cycle but may also cause hidden damage to the components due to forced installation. When the equipment is running, vehicle vibration will aggravate the mutual friction and collision between the two, which may lead to sealing failure of the lubrication line 100 and lubricating oil leakage, or even reduce the detection accuracy of the encoder 2 or even cause structural damage, affecting the reliability of the system. During maintenance, the narrow space of the interference area makes it difficult to carry out operations such as maintenance of the lubrication line 100 and debugging of the encoder 2, which greatly increases maintenance costs and downtime.

[0004] Therefore, it is urgent to improve the arrangement of the lubrication pipeline 100 to avoid interference with the encoder 2, and at the same time provide an anti-interference structure for the lubrication pipeline of the test wheel to ensure lubrication function. Utility Model Content

[0005] The purpose of this invention is to provide an anti-interference structure for detecting wheel lubrication lines, thereby solving the problems mentioned in the background art.

[0006] To achieve the above objectives, the main technical solutions adopted by this utility model include:

[0007] An anti-interference structure for detecting wheel lubrication lines includes lubrication lines respectively disposed on end caps on both sides of the wheel. The lubrication lines are integrally machined within the end caps, with one end connected to the lubrication channel of the bearing and the other end equipped with a grease nipple.

[0008] The two end caps are divided into end caps that are close to the encoder and end caps that are far away from the encoder.

[0009] In the end cover near the encoder, the lubrication line is located in the area below the end cover and extends radially along the end cover;

[0010] In the end cover away from the encoder, the lubrication line is located in the lateral region of the end cover and extends axially along the end cover;

[0011] The grease nipple is provided with a dustproof component on its outer side.

[0012] As a preferred technical solution, the port of the lubrication pipeline and the grease nipple are connected by a tapered thread seal.

[0013] As a preferred technical solution, the connection between the lubrication pipeline port and the grease nipple is coated with anaerobic sealant.

[0014] As a preferred technical solution, the dustproof assembly includes a dustproof cap sleeved on the outside of the grease nipple, and a support fixedly connected to the surface of the end cap and surrounding the grease nipple, wherein the dustproof cap and the support are detachably connected.

[0015] As a preferred technical solution, the outer surface of the dust cap is connected to the inner wall of the support by a thread.

[0016] As a preferred technical solution, the outer surface of the dust cap is fixedly connected with several annularly distributed convex strips, which are located on the outside of the support and are used to increase the friction force during screwing.

[0017] As a preferred technical solution, the inner cavity of the dust cap is fitted with an O-ring seal, which is tightly pressed against the surface of the grease nipple to seal the mating surfaces of the dust cap and the grease nipple.

[0018] As a preferred technical solution, with the wheel rotation axis as a reference, the lower region is the lower part of the end cover in the direction of gravity, and the lateral region is the radial side of the end cover.

[0019] This utility model has at least the following beneficial effects:

[0020] This application addresses the problem of interference in traditional designs by arranging the lubrication lines near the encoder in the area below the end cover and extending radially, while arranging the lubrication lines away from the encoder in the area to the side of the end cover and extending axially. This completely separates the lubrication lines from the encoder in space, fundamentally solving the interference problem and ensuring the structural integrity of the encoder and lubrication lines. Furthermore, the lubrication lines are integrally machined inside the end cover, reducing connection nodes and exposed parts. This not only makes the overall structure more compact but also reduces the risk of lubrication line loosening and leakage. Attached Figure Description

[0026] 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.

[0027] Please see Figures 1-3 This utility model provides an anti-interference structure for detecting wheel lubrication lines, including lubrication lines 100 respectively disposed on end caps 1 on both sides of the wheel. The lubrication lines 100 are integrally machined inside the end caps 1, with one end connected to the lubrication channel of the bearing and the other end provided with a grease nipple 200. The two end caps 1 are divided into end caps adjacent to the encoder 2 and end caps away from the encoder 2. In the end cap 1 adjacent to the encoder 2, the lubrication line 100 is located in the lower region of the end cap 1 and extends radially along the end cap 1. In the end cap 1 away from the encoder 2, the lubrication line 100 is located in the lateral region of the end cap 1 and extends axially along the end cap 1. A dustproof component 300 is provided on the outside of the grease nipple 200.

[0028] The port of the lubrication pipeline 100 is connected to the grease nipple 200 by a tapered thread seal. The tapered thread seal between the port of the lubrication pipeline 100 and the grease nipple 200 utilizes the mechanical locking characteristics of the thread itself to achieve a tight fit between the two, which enhances the sealing performance and structural stability of the connection and avoids the defects of loosening and leakage that are common in traditional flat-end connections.

[0029] The connection between the lubrication pipeline 100 port and the grease nipple 200 is coated with anaerobic sealant; the tapered thread connection is also coated with anaerobic sealant. Through the filling and curing of the sealant layer, the thread gap is further filled, forming a durable sealing layer, which effectively prevents the lubricating medium from leaking under vibration conditions and enhances the sealing reliability.

[0030] The dustproof component 300 includes a dust cap 310 sleeved on the outside of the grease nipple 200 and a support 320 fixedly connected to the surface of the end cap 1 and surrounding the grease nipple 200. The dust cap 310 and the support 320 are detachably connected. Through the cooperation of the dust cap 310 and the support 320, the dustproof component 300 isolates the grease nipple 200 from the external environment, preventing dust and impurities from adhering to or entering the grease nipple channel, ensuring the cleanliness of the lubricating medium, and protecting the grease nipple from collision damage.

[0031] The outer surface of the dust cap 310 is connected to the inner wall of the support 320 by a thread. The threaded connection between the dust cap 310 and the support 320 not only ensures the stable installation of the dust cap 310, but also enables convenient disassembly and assembly, facilitating regular grease injection. Compared with connection methods such as snap-fit, it is more suitable for long-term use in vibration environments.

[0032] The outer surface of the dust cap 310 is fixedly connected with several annularly distributed protrusions. The protrusions are located on the outside of the support 320 and are used to increase the friction when screwing. The annular protrusions on the outer surface of the dust cap 310 increase the friction between the hand and the cap body, so that the operator can easily tighten or loosen the dust cap 310 without tools, thus improving the convenience of maintenance operations.

[0033] The dust cap 310 has an O-ring 330 embedded in its inner cavity. The O-ring 330 is tightly pressed against the surface of the grease nipple 200 to seal the mating surfaces of the dust cap 310 and the grease nipple 200. The O-ring 330 in the inner cavity of the dust cap 310 is tightly pressed against the surface of the grease nipple 200 through elastic deformation, forming an elastic seal between the dust cap 310 and the grease nipple 200, further preventing moisture and dust from entering, while buffering the rigid contact between the dust cap 310 and the grease nipple 200 and protecting the surface of the component.

[0034] With the wheel rotation axis as the reference, the lower region is the lower part of the end cover 1 in the direction of gravity, and the side region is the radial side of the end cover 1.

[0035] The working principle of this utility model is as follows:

[0036] The lubricating medium is injected through the grease nipple 200 and delivered to the lubrication channel of the bearing through the lubrication pipeline 100 integrally machined inside the end cover 1, providing continuous lubrication for the bearing; the lubrication pipeline 100 on the side adjacent to the encoder 2 extends radially along the end cover 1 to the lower area, and the lubrication pipeline 100 on the side away from the encoder 2 extends axially along the end cover 1 to the side area. Both of them avoid the installation space of the encoder 2, ensuring that the lubrication process does not interfere with the speed detection.

[0037] In the non-greasing state, the dust cap 310 is connected to the support 320 by threads, and the O-ring 330 in its inner cavity is tightly attached to the grease nipple 200 to form a closed protective space to prevent external impurities from entering; when greasing, the dust cap 310 can be unscrewed to complete the operation through the grease nipple 200, and the protection can be restored by reinstalling the dust cap 310 after the operation.

[0038] Encoder 2 stably acquires wheel speed signals in a space with 100° interference from lubrication lines, while the bearings maintain smooth rotation under continuous lubrication. The two achieve functional synergy through optimized structural layout, ensuring the overall reliability of the wheel detection system.

[0039] All parts not described in this utility model are the same as or can be implemented using existing technology. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of this utility model, the scope of which is defined by the appended claims and their equivalents.
