Description

Technical Field

[0001] This utility model relates to the technical field of CDC vibration dampers, and in particular to an electromagnet structure for improving performance consistency. Background Technology

[0002] Currently, there are two types of magnetic circuit structures for the inner diameter of the coil in CDC vibration damper proportional control valve products on the market: one is a component structure that is press-fitted and welded after machining, which mainly has the disadvantage of relatively high processing costs; the other is an integral structure with a cut groove. Because the inclined surface of the magnetic circuit groove is obstructed inside the housing and the space is narrow, the radial and axial dimensions are more difficult to detect, which poses a risk of inconsistent processing and inspection. Since the inclined surface of this groove has a significant impact on the electromagnetic force of the product, the consequence is an impact on the consistency of the CDC vibration damper proportional control valve, ultimately reducing the performance of the CDC proportional control valve. Utility Model Content

[0003] To address the shortcomings and defects of existing technologies, this invention provides an electromagnet structure that improves performance consistency. To achieve the goal of improving detection consistency, this invention provides the following technical solution.

[0004] An electromagnet structure for improving performance consistency includes an outer shell and a magnetic sleeve assembly. The magnetic sleeve assembly includes a sleeve. The outer shell has a mounting hole. The magnetic sleeve assembly is fitted into the mounting hole. The outer side of the sleeve has a first mating platform. The inner side of the outer shell extends towards the sleeve and has a second mating platform. The first mating platform and the second mating platform are interference-fitted. The magnetic sleeve assembly is fixedly installed in the outer shell.

[0005] Compared with the prior art, this utility model has a first mating platform in the outer shell and a second mating platform on the sleeve of the magnetic sleeve assembly. Through the abutting and mating of the first and second mating platforms, the magnetic sleeve assembly can be well set in the outer shell, and can completely avoid obstructions in space during the testing process, which is convenient for processing and testing.

[0006] Furthermore, the first mating platform is provided with a first limiting surface and a first radial surface, and the second mating platform is provided with a second limiting surface and a second radial surface. The first mating platform and the second mating platform are configured to be interference fit, which means that the first limiting surface and the second limiting surface abut against each other, and the first radial surface is configured to be ...

[0007] Through the above improvements, a first limiting surface and a radial surface are provided on the first mating platform, and a second limiting surface and an abutting surface are provided on the second mating platform. The first limiting surface abuts against the second limiting surface, and the first radial surface is mated with the outer wall of the sleeve, while the second radial surface abuts against the inner wall of the outer shell. This improves the mating effect between the first mating platform and the second mating platform and enhances the stability of the assembly.

[0008] Furthermore, the magnetic sleeve assembly includes an armature and a front yoke disposed within the sleeve. A rear bearing is disposed between the armature and the sleeve. An assembly groove is disposed within the sleeve. The rear bearing is installed within the assembly groove, and the outer wall of the rear bearing is fitted with the side wall of the assembly groove.

[0009] Through the above improvements, the magnetic sleeve assembly is equipped with an armature and a front yoke. The rear bearing between the armature and the sleeve can reduce friction, provide support, and keep the center position of the armature stable.

[0010] Furthermore, a front bearing is provided between the armature and the front yoke sleeve. The front bearing is sleeved on the outer wall of the armature near the front yoke sleeve, and the outer wall of the front bearing abuts against the inner wall of the front yoke sleeve.

[0011] Through the above improvements, a front bearing is provided between the armature and the front yoke sleeve, which can improve the connection firmness and sealing.

[0012] Furthermore, a third limiting surface is provided inside the sleeve, and a fourth limiting surface is provided on the front yoke sleeve. The front yoke sleeve is disposed inside the sleeve, and the third limiting surface abuts against the fourth limiting surface.

[0013] Through the above improvements, a third limiting surface is provided inside the sleeve, and a fourth limiting surface is provided on the front yoke sleeve. The third limiting surface and the fourth limiting surface abut against each other, so that the front yoke sleeve can be set more stably inside the sleeve, preventing shaking during use.

[0014] Furthermore, a mating cavity is formed between the first mating platform and the sleeve, and a sealing ring is fixedly disposed in the mating cavity. One end of the sealing ring abuts against the outer wall of the sleeve, and the other end abuts against the first mating platform.

[0015] Through the above improvements, a sealing ring is installed between the first mating platform and the sleeve, which can improve the reliability of the seal between the outer shell and the sleeve.

[0016] Furthermore, the outer wall of the sleeve is provided with a process groove in the radial direction.

[0017] With the above improvements, the process tank can be easily processed and inspected.

[0018] Furthermore, a mounting groove is provided on the end of the outer shell away from the magnetic sleeve assembly.

[0019] With the above improvements, mounting slots are provided on the outer casing, which facilitates installation with other components and improves the stability during installation. Attached Figure Description
