Description

Technical Field

[0001] This application relates to the field of vehicle technology, and more particularly to a clutch assembly and a vehicle. Background Technology

[0002] In electric drive systems, the power input shaft inevitably produces flexural oscillations when rotating at high speeds. These oscillations severely affect the normal operation of traditional electromagnetic clutches: the armature is often unable to engage properly due to interference from the high-speed rotation of the shaft; the sensor bracket is prone to deformation under the impact of shaft oscillations, leading to sensor failure; and the electromagnetic force fluctuates due to air gap instability, causing NVH problems and affecting the clutch's service life.

[0003] Therefore, improving the reliability of clutch components is a technical problem that urgently needs to be solved. Utility Model Content

[0006] According to the clutch assembly proposed in the first aspect of this application, the first segment is used to radially constrain the receiving component, so that the gap between the receiving component and the electromagnetic drive component remains stable throughout the entire sliding stroke. This avoids electromagnetic force instability caused by air gap changes, reduces the probability of the receiving component deflecting, jamming, or radially moving as the shaft swings, and improves structural reliability.

[0007] Optionally, the first segment has a guide groove along the radial direction of the power output shaft, the guide groove extends through the first segment and extends along the axial direction of the power output shaft, and the sliding sleeve assembly is provided with a protrusion that extends radially along the power output shaft and passes through the guide groove to connect with the receiving member.

[0008] In the above scheme, the above structure helps to maintain the precise movement trajectory of the sliding sleeve assembly and the smooth and reliable engagement and disengagement of the clutch.

[0009] Optionally, along the axial direction of the power output shaft, the guide groove extends through the end face of the first section away from the second section.

[0010] In the above scheme, the above structure makes it easy for the protrusion of the sliding sleeve assembly to be directly inserted into the guide groove from the end of the first section, which greatly simplifies the assembly process and reduces the assembly difficulty.

The bearing is fitted onto the body and fixed to the body. The bracket is disposed on the bearing, and the protrusion is disposed on the bracket.

[0016] In the above scheme, the above structure can ensure smooth power transmission and improve the clutch's action accuracy and operational reliability under rotating conditions.

[0017] Optionally, the bracket has a limiting groove, and the outer ring of the bearing is embedded in the limiting groove so that the outer ring of the bearing is fixedly connected to the bracket.

[0018] In the above solution, the structure can achieve a firm fixation between the outer ring of the bearing and the bracket, preventing relative rotation or movement between the two during operation and sliding, and ensuring that the driving force is stably transmitted from the bracket to the bearing and the body.

[0019] Optionally, the bracket is equipped with a sensor along the axial direction of the power input shaft, the sensor being adapted to detect the displacement of the sleeve assembly.

[0020] In the above scheme, the above structure can accurately detect the axial displacement of the receiving component, which helps to improve the stability and accuracy of displacement detection.

[0021] Optionally, the body includes a first ring segment and a second ring segment. The outer diameter of the first ring segment is larger than the outer diameter of the second ring segment to form a first stepped surface. The bearing is sleeved on the first ring segment and abuts against the first stepped surface. The sliding sleeve assembly also includes a retaining ring, which is sleeved on the first ring segment and abuts against the end of the bearing away from the first stepped surface.

[0022] In the above scheme, the above structure can securely assemble the bearing on the first ring segment, ensuring that the bearing assembly position is accurately fixed.

Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0030] Unless otherwise defined, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains; the terminology used in the description of this application is for the purpose of describing particular embodiments only and is not intended to limit the application; the terms "comprising" and "having," and any variations thereof, in the description, claims, and accompanying drawings of this application are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the description, claims, or accompanying drawings of this application are used to distinguish different objects, not to describe a specific order or hierarchy.

[0031] In this application, the reference to "embodiment" means that a specific feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described in this application can be combined with other embodiments.

[0032] In electric drive systems, a clutch is typically placed between the rotating shaft and the idler gear to enable power transmission and interruption. Common solutions for achieving similar functionality in related technologies include: 1. Traditional wet multi-plate clutches transmit torque by pressing multiple sets of friction plates together through hydraulic or electric actuators. They typically include components such as a clutch hub, piston, pressure plate, friction plate assembly, spring, and retaining ring. Their axial and radial dimensions are large, and their supporting systems are complex (including hydraulic pumps, valve bodies, cooling oil circuits, etc.), occupying internal space in the electric drive system. Furthermore, the friction plates are prone to overheating and wear at high speeds.

[0033] 2. An electromagnetic dog-tooth clutch or a mechanical dog-clutch, a "dog-clutch electromagnetic clutch" technical solution includes a movable toothed sleeve and a fixed toothed sleeve that mesh and drive each other. After the electromagnetic coil is energized, the movable armature is attracted to the fixed armature to complete the engagement. Its structure is compact and has no auxiliary actuation structure. However, the above solution still has the problem that the gap between the fixed armature and the movable armature is not easy to control. If the gap is too large, the electromagnetic attraction force is insufficient; if it is too small, it is easy to cause contact friction damage.

[0034] 3. A bistable electromagnetic clutch has a guide pin on the magnetic yoke and a guide hole on the armature disc. The guide pin and the guide hole form an axial relative movement guide, and a magnet is used to achieve bistable holding. However, this scheme mainly solves the problems of energy consumption and heat generation. Its sensor induction coil is set on the guide pin, the structure is complex, and the impact of shaft flexibility on engagement reliability is not considered.

[0035] The existing solutions mentioned above are effective under normal operating conditions, but when applied to the internal shaft system of an electric drive system with extremely high reliability requirements, they have failed to adequately solve the reliability problems caused by the high-speed operation and flexible oscillation of the shaft system.

[0036] Specifically, current electromagnetic clutches lack reliable guiding mechanisms on the shaft system for the armature, or rely solely on a single guiding surface. When the shaft system rotates at high speeds, it undergoes flexible oscillations, causing the armature's axial movement trajectory to deviate and preventing the formation of a stable air gap with the electromagnetic coil. This unstable air gap leads to severe fluctuations in electromagnetic force, resulting not only in incomplete armature engagement but also NVH (noise, vibration, and harshness) problems caused by electromagnetic force instability. Furthermore, the sensor bracket is independently mounted on a sliding sleeve, which is located on the shaft system. Under high-speed oscillating impacts, the sensor bracket is prone to deformation, leading to sensor failure and inaccurate feedback on the clutch engagement / disengagement status.

[0037] In view of this, in order to improve the reliability of the clutch assembly, this application proposes a clutch assembly in which the receiving member is slidable relative to the first segment along the axial direction of the power input shaft. The receiving member is poweredly connected to the sliding sleeve assembly so as to drive the sliding sleeve assembly to move under the drive of the electromagnetic drive member, so as to engage or disengage the power output shaft and the power input shaft. The first segment is used to radially constrain the receiving member, so that the gap between the receiving member and the electromagnetic drive member remains stable throughout the entire sliding stroke. This avoids the problems of unstable electromagnetic force, delayed response or insufficient suction caused by changes in the air gap, reduces the probability of the receiving member deflecting, jamming or radially moving with the shaft system, and improves the structural reliability.

[0038] The following description, with reference to the accompanying drawings, illustrates an embodiment of a clutch assembly and a vehicle proposed in this application.

[0039] like Figure 1 As shown, the clutch assembly according to the first aspect of this application includes a power output shaft 100, a sliding sleeve assembly 200, a power input shaft 300, a first housing 400, an electromagnetic drive member 500, and a receiver 600.

[0040] The sliding sleeve assembly 200 is sleeved on the power output shaft 100 and is connected to the power output shaft 100 in a transmission manner; the power input shaft 300 is coaxially connected to the power output shaft 100.

[0041] The first housing 400 includes a first segment 410 and a second segment 420. The first segment 410 is sleeved on the sliding sleeve assembly 200, and the second segment 420 is connected to the first segment 410 and extends radially along the power output shaft 100. Specifically, the second segment 420 can be fixedly connected to the electric drive housing, so that the first segment 410 and the second segment 420 can be fixed to the electric drive housing as a whole to ensure stability.

[0042] Specifically, the first segment 410 and the second segment 420 are constructed as a single molded part.

[0043] The electromagnetic drive 500 is fixed to the second section 420 along the axial direction of the power output shaft 100. The receiver 600 is slidable relative to the first section 410. The receiver 600 is poweredly connected to the sliding sleeve assembly 200 so as to move the sliding sleeve assembly 200 under the drive of the electromagnetic drive 500. It can be understood that the receiver 600 can be configured as an armature and move under the drive of the electromagnetic drive 500 to engage or disengage the power output shaft 100 and the power input shaft 300.

[0044] This reduces the occurrence of flexible swaying and radial runout of the receiver 600, allowing the receiver 600 to maintain a stable motion posture without skewing, jamming, or radial movement, thus avoiding incomplete engagement, incomplete separation, or jamming due to flexible swaying.

[0045] Specifically, the first segment 410 provides continuous and complete circumferential support and radial positioning for the receiver 600, ensuring that the air gap between the receiver 600 and the electromagnetic drive 500 remains uniform and stable throughout the entire sliding stroke. This guarantees that the relative position of the armature and the electromagnetic coil remains unchanged, preventing sudden changes in air gap size and severe fluctuations in electromagnetic force, and reducing problems such as electromagnetic instability, delayed response, or insufficient attraction.

[0046] Furthermore, due to the constant air gap and stable motion of the receiver 600, the electromagnetic attraction force generated by the electromagnetic drive 500 after energization is controllable in magnitude and precise in direction, enabling stable axial movement of the receiver 600 without issues such as uneven attraction or excessive lateral force. This facilitates precise control of the engagement speed and force of the sliding sleeve assembly 200, achieving smooth engagement and disengagement between the power input shaft 300 and the sliding sleeve assembly 200, avoiding impacts, abnormal noises, and tooth surface collisions. It also improves the repeatability and consistency of clutch actions, extending the service life of the meshing tooth surfaces.

[0047] In some embodiments, such as Figure 1As shown, the first segment 410 has a guide groove 411 along the radial direction of the power output shaft 100. The guide groove 411 extends through the first segment 410 and extends along the axial direction of the power output shaft 100. The sliding sleeve assembly 200 is provided with a protrusion 210, which extends along the radial direction of the power output shaft 100. The protrusion 210 passes through the guide groove 411 and connects to the receiving member 600.

[0048] This design achieves direct and rigid power transmission between the receiving component 600 and the sliding sleeve assembly 200, ensuring stable transmission of axial driving force. It also utilizes the guide groove 411 to provide axial guidance for the protrusion 210, which, together with the external guidance of the first section 410 for the receiving component 600, constitutes a double internal and external guiding constraint. This helps maintain the precise movement trajectory of the sliding sleeve assembly 200 and the smooth and reliable engagement and disengagement of the clutch. At the same time, the structure is compact and the stress is reasonable, improving the overall operational stability.

[0049] In some embodiments, such as Figure 2 As shown, along the axial direction of the power output shaft 100, the guide groove 411 penetrates the end face of the first section 410 away from the second section 420. This facilitates the direct insertion of the protrusion 210 of the sliding sleeve assembly 200 into the guide groove 411 from the end of the first section 410, greatly simplifying the assembly process and reducing assembly difficulty.

[0050] In some embodiments, such as Figure 1 As shown, the receiving component 600 has a fixing groove 610 with its opening facing the first segment 410, and the protrusion 210 passes through the guide groove 411 and engages with the fixing groove 610. This enables circumferential positioning and axial limiting between the protrusion 210 and the receiving component 600, preventing relative wobbling or loosening during movement, ensuring more stable and reliable transmission of driving force, making the connection between the receiving component 600 and the sliding sleeve assembly 200 more precise and secure, and improving the smoothness and reliability of clutch operation.

[0051] In some embodiments, there are multiple protrusions 210, guide grooves 411, and fixing grooves 610. Each protrusion 210 passes through a corresponding guide groove 411 and engages with a corresponding fixing groove 610. Multiple protrusions 210 are spaced apart along the circumference of the power output shaft 100. This structure enables circumferential positioning and axial limiting between the protrusions 210 and the receiving member 600, preventing relative wobbling or loosening during movement and ensuring more stable and reliable transmission of driving force.

[0052] In some specific embodiments, there are two protrusions 210, guide grooves 411 and fixing grooves 610, which are located on the radial sides of the power output shaft 100 respectively.

[0053] In some embodiments, such as Figure 1As shown, the sliding sleeve assembly 200 includes a body portion 220, a bracket 230, and a bearing 240. The body portion 220 is sleeved on the power output shaft 100 and can be selectively engaged with the power input shaft 300. The bearing 240 is sleeved on the body portion 220 and is fixedly installed on the body portion 220. The bracket 230 is disposed on the bearing 240, and the protrusion 210 is disposed on the bracket 230.

[0054] The bracket 230 can move smoothly with the bearing 240 under the guidance of the first section 410, completely avoiding the damage to the sensor 700 caused by shaft wobble and speed difference impact. When the receiver 600 moves, the receiver 600 drives the bearing 240 to move through the bracket 230, which in turn drives the main body 220 to move axially along the power output shaft 100. The bearing 240 and the bracket 230 can stably transmit axial driving force, ensuring smooth power transmission and improving the action accuracy and operational reliability of the clutch under rotating conditions.

[0055] In some embodiments, such as Figure 1 As shown, the bracket 230 has a limiting groove 231, and the outer ring of the bearing 240 is embedded in the limiting groove 231 to fix the outer ring of the bearing 240 to the bracket 230. This can achieve a firm fixation between the outer ring of the bearing 240 and the bracket 230, preventing relative rotation or movement between the two during operation and sliding, ensuring that the driving force is stably transmitted from the bracket 230 to the bearing 240 and the body 220. At the same time, this limiting structure is simple to assemble and has precise positioning, which can effectively maintain the overall rotational fit accuracy, reduce abnormal wear and vibration, and further ensure that the clutch can still operate smoothly and reliably under shaft swing conditions.

[0056] Specifically, the bracket 230 includes a first part and a second part connected in sequence. Along the axial direction of the power output shaft 100, the first part and the second part are clamped on the outer ring of the bearing 240, and the first part is provided with a protrusion 210.

[0057] In some embodiments, such as Figure 1 As shown, the bracket 230 is equipped with a sensor 700, which is suitable for detecting the displacement of the sliding sleeve assembly 220. This enables precise detection of the axial displacement of the receiving component 600, facilitating accurate acquisition of the engagement and disengagement positions of the sliding sleeve assembly 200, providing feedback signals for precise clutch control. Simultaneously, the sensor 700 moves synchronously with the bracket 230, ensuring that the detection reference is consistent with the movement references of the receiving component 600 and the sliding sleeve assembly 200. This avoids detection errors caused by shaft oscillation and housing deformation, improving the stability and accuracy of displacement detection. Ultimately, this achieves closed-loop control of the clutch engagement and disengagement process, enhancing the action response speed and control precision.

[0058] Specifically, the second part of the bracket 230 extends radially along the power output shaft 100 and axially along the power output shaft 100. The second part is opposite to and spaced apart from the second segment 420, and the sensor 700 is disposed at the end of the second part.

[0059] In some embodiments, such as Figure 1 As shown, the main body 220 includes a first ring segment 221 and a second ring segment 222. The outer diameter of the first ring segment 221 is larger than the outer diameter of the second ring segment 222 to form a first stepped surface 223. The bearing 240 is sleeved on the first ring segment 221 and abuts against the first stepped surface 223. The sliding sleeve assembly 200 also includes a retaining ring 250, which is sleeved on the first ring segment 221 and abuts against the end of the bearing 240 away from the first stepped surface 223.

[0060] This design ensures that the bearing 240 is securely mounted on the first ring segment 221. One side of the bearing 240 is axially stopped and positioned by the first stepped surface 223, while the other side is locked and limited by the snap ring 250. This effectively prevents the bearing 240 from axially shifting, deviating, or loosening during equipment operation and clutch engagement / disengagement, ensuring that the bearing 240 is precisely fixed in its assembly position. This structure provides reliable positioning and convenient assembly, and can stably constrain the fit accuracy between the bearing 240 and the body 220 and bracket 230. It avoids component wear and movement jamming caused by the bearing 240 shaking, ensuring smooth transmission of clutch drive power and precise operation, and effectively improving the overall operational stability and service life of the clutch.

[0061] The process of joining and separating the power input shaft 300 and the power output shaft 100 in the embodiments of this application is briefly described below.

[0062] The electromagnetic drive 500 generates a magnetic pull when a positive current is applied, which drives the receiver 600. The receiver 600 drives the sliding sleeve assembly 200 to move axially through the protrusion 210. The outer ring of the bearing 240 is fixed to the bracket 230 and moves axially with the bracket 230. The inner ring of the bearing 240 moves with the outer ring and rotates with the power output shaft 100 along with the body 220 of the sliding sleeve assembly 200. The protrusion 210 slides in the guide groove 411. The sliding sleeve assembly 200 slides along the outer surface of the power output shaft 100 until the end face teeth at one end of the axial direction mesh with the end face teeth of the power input shaft 300, thereby realizing the power connection between the power output shaft 100 and the power input shaft 300.

[0063] A reverse current is applied to the electromagnetic drive component 500 to generate a magnetic pull force, which drives the receiver 600 in the reverse direction. The receiver 600 drives the sliding sleeve assembly 200 to move in the reverse direction along the axial direction. The outer ring of the bearing 240 is fixed to the bracket 230 and moves in the axial direction along with the bracket 230. The inner ring of the bearing 240 moves with the outer ring and rotates together with the body 220 of the sliding sleeve assembly 200 along with the power output shaft 100. The protrusion 210 slides in the guide groove 411. The sliding sleeve assembly 200 moves in the reverse direction along the outer surface of the power output shaft 100. The end face teeth of the sliding sleeve assembly 200 separate from the end face teeth of the power input shaft 300, thereby realizing that the power output shaft 100 and the power input shaft 300 are no longer connected.
