Description

Technical Field

[0001] The utility model relates to the technical field of coil structures, in particular to an electromagnetic coil structure of a claw-type clutch mechanism. Background Art

[0002] With the development of new energy vehicles, electric and hybrid vehicles have experienced rapid growth. This has provided a wider range of vehicle powertrain options. The implementation of multi-gear architectures in electric vehicles and series-parallel architectures in hybrid vehicles effectively manage powertrain energy, reducing energy consumption and improving efficiency. The claw clutch solenoid coil structure is used within reduction gearboxes to achieve clutch shifting and can be used in automotive electromagnetic clutches.

[0003] Chinese utility model patent publication number CN111473063B discloses an electromagnetic clutch and clutch assembly, relating to the field of clutch technology. The electromagnetic clutch comprises an active rotating clutch portion and a driven rotating clutch portion rotatably arranged along a first rotational center axis, a clutch bearing, an energized coil, an armature, and a clamping member. The clutch bearing is disposed between the active rotating clutch portion and the driven rotating clutch portion, with a gap defined therebetween. The armature is rotatably disposed about the first rotational center axis, and the clamping member is disposed within the gap and fixedly connected to the armature. With this arrangement, when the energized coil is de-energized, the upper end surface of the armature is pressed against the active rotating clutch portion, the clamping member is retained in the gap, and the active rotating clutch portion, the driven rotating clutch portion, the clamping member, and the armature all rotate synchronously. When the energized coil is energized, the energized coil attracts the armature to move, causing the armature and the energized coil to engage, while simultaneously reducing the friction between the clamping member and the active rotating clutch portion, causing the armature, the clamping member, and the driven rotating clutch portion to stop rotating.

[0004] The aforementioned electromagnetic clutch and clutch assembly have an excessively large actuator mechanism. Acceleration often occurs on the clutch during vehicle operation due to factors such as acceleration and deceleration, and uneven road conditions. This large actuator mechanism also results in a heavy weight, making it susceptible to unexpected oscillation due to the clutch spring's elastic force during operation. This increases wear on the actuator mechanism and can even negatively impact clutch control. Consequently, the existing technology suffers from poor reliability. Utility Model Content

[0035] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with embodiments, but the scope of protection claimed in the present invention is not limited to the following specific embodiments.

[0036] refer to Figure 1 and Figure 2, an electromagnetic coil structure of a claw-type clutch mechanism, comprising a rotating shaft 11, a coil housing 31, an outer ring 21 of an executing ring, and an inner ring 22 of an executing ring. The inner ring 22 of the executing ring is sleeved on the rotating shaft 11, and the inner ring 22 of the executing ring is slidably connected to the rotating shaft 11 and circumferentially clamped. The rotating shaft 11 is installed with a limiting ring 12, and the limiting ring 12 is clamped with the inner ring 22 of the executing ring. The inner ring 22 of the executing ring is limited by the limiting ring 12, so as to control the movement stroke of the inner ring 22 of the executing ring. One end of the inner ring 22 of the executing ring is fixedly connected with a push block 23, and the inner ring 22 of the executing ring is located between the limiting ring 12 and the push block 23, so as to limit the side of the inner ring 22 of the executing ring away from the push block 23. The outer ring 21 of the executing ring is fixedly installed on the outer wall of the inner ring 22 of the executing ring, and the outer ring 21 of the executing ring is clamped with the push block 23. A clearance gap 13 is provided between the push block 23 and the rotating shaft 11. Since the inner ring 22 of the execution ring of this application pushes the clutch to move through the push block 23, when the push block 23 contacts the object being pushed, the push block 23 is subjected to a certain amount of pressure and is prone to deformation. By providing a clearance gap 13 between the push block 23 and the rotating shaft 11, space is provided for the push block 23 to deform, preventing the push block 23 from being squeezed onto the rotating shaft 11 when deformed, preventing the surface of the rotating shaft 11 from being damaged by friction caused by the push block 23, and preventing the push block 23 from being stuck on the rotating shaft 11 and unable to move normally, thereby improving reliability. A plurality of push blocks 23 are provided, and the plurality of push blocks 23 are evenly distributed around the rotating shaft 11. By using a plurality of push blocks 23 evenly distributed around the rotating shaft 11 to push the clutch to move, the force on the inner ring 22 of the execution ring is more balanced, reducing the torque on the inner ring 22 of the execution ring, and improving structural stability. An oil groove 15 is defined on the inner wall of the actuator ring inner ring 22, and an oil hole 14 is defined in the rotating shaft 11. Oil hole 14 communicates with the oil groove 15. Lubricating oil is injected into the oil hole 14 and flows through the oil hole 14 into the oil groove 15, facilitating the lubrication of the actuator ring inner ring 22. This reduces friction between the actuator ring inner ring 22 and the rotating shaft 11, minimizing wear and improving reliability.

[0037] The coil housing 31 is provided with a coil mounting slot 32, which houses an electromagnetic coil 33 positioned within the slot. A coil end cap 34 is mounted on the coil housing 31, blocking the opening of the slot 32. A connecting plate 35 is fixedly attached to the outer wall of the coil housing 31, and the connecting plate 35 has a connecting hole 36. The rotating shaft 11 is rotationally connected to the transmission housing, and the connecting plate 35 is fixedly mounted to the transmission via the connecting hole 36. Screws inserted through the connecting hole 36 facilitate secure attachment of the connecting plate 35 to the transmission, facilitating installation of the connecting plate 35.

[0038] A gap 24 is provided between the outer wall of the actuator ring outer ring 21 and the inner wall of the coil housing 31. This reduces friction and wear between the two, thereby minimizing the resistance experienced by the rotating shaft 11 during rotation. A through slot 25 is provided between the coil end cap 34 and the push block 23, minimizing friction and wear between the two, thereby minimizing the resistance experienced by the rotating shaft 11 during rotation. The through slot 25 communicates with the gap 24.

[0039] Specific working process:

[0040] The outer ring 21 of the actuator ring is made of magnetic conductive material. After the electromagnetic coil 33 is energized, the electromagnetic coil 33 generates a circular magnetic field. The magnetic field forms a circular magnetic field through the coil housing 31, the coil end cover 34 and the outer ring 21 of the actuator ring. Under the action of the circular magnetic field, the outer ring 21 of the actuator ring is subjected to the axial electromagnetic force of the rotating shaft 11 and moves. The outer ring 21 of the actuator ring drives the push block 23 to move, realizing the function of driving the push block 23 to move, and then the clutch can be driven by the push block 23 to complete the clutch shifting action.

[0041] This embodiment has the following advantages:

[0042] In the present application, the outer ring 21 and the inner ring 22 of the execution ring are both arranged on the inner side of the coil housing 31, thereby greatly reducing the diameter of the outer ring 21 and the inner ring 22 of the execution ring, thereby reducing the volume and weight of the outer ring 21 and the inner ring 22 of the execution ring, effectively reducing the impact of the outer ring 21 and the inner ring 22 of the execution ring during shaking, and then preventing the inner ring 22 and the outer ring 21 of the execution ring from accidentally shaking due to overcoming the elastic force of the clutch spring, reducing wear, and improving the reliability of the clutch, achieving the advantage of better reliability.

[0043] The inner ring 22 of the actuator ring pushes the clutch to move through the push block 23, and the volume and weight of the push block 23 are much smaller than the volume and weight of the inner ring 22 of the actuator ring, which can further reduce the impact of the outer ring 21 and the inner ring 22 of the actuator ring during shaking, thereby preventing the inner ring 22 and the outer ring 21 of the actuator ring from shaking accidentally due to overcoming the elastic force of the clutch spring, thereby improving the reliability of the clutch.

[0044] The outer ring 21 and the inner ring 22 of the actuator ring are both arranged inside the coil housing 31, which makes the structure more compact, reduces the space occupied by the coil structure, and facilitates installation.

[0045] When the outer ring 21, the inner ring 22 and the push block 23 of the actuator ring move on the rotating shaft 11, the gas on both sides of the coil housing 31 will be driven to move. By setting the through groove 25 and the gap 24, the air on both sides of the coil housing 31 can flow through the through groove 25 and the gap 24, preventing the air from being blocked and causing excessive pressure changes, reducing the resistance encountered by the outer ring 21, the inner ring 22 and the push block 23 during movement, and preventing the pressure difference from being too large to affect the reliability of the seals in the gearbox.

Therefore, the present invention is not limited to the specific embodiments disclosed and described above, and modifications and variations of the present invention should also fall within the scope of protection of the claims of the present invention. In addition, although certain specific terms are used in this description, these terms are for convenience only and do not constitute any limitation on the present invention.
