Description

[Technical Field]

[0001] The present invention relates to a disconnector device capable of switching between four-wheel drive and two-wheel drive. [Background technology]

[0002] Generally, a disconnector device can minimize unnecessary power loss by disconnecting or connecting the differential shaft depending on the driving situation and switching the power between two-wheel drive (2WD) and four-wheel drive (4WD).

[0003] The disconnector device can include a case body, a cover coupled to the case body, a support ring attached to the inside of the case body, a differential gear set consisting of a pinion gear attached to the inside of the support ring and left and right side gears meshing with the pinion gear, and a clutch ring meshing with the support ring inside the case body.

[0004] When the actuator device is operated, a sleeve connected to the actuator device moves in an interlocking direction. As the sleeve moves in the interlocking direction, a clutch ring connected to the sleeve moves toward the support ring, resulting in an interlocking state in which the teeth of the clutch ring mesh with the teeth of the support ring. This allows for four-wheel drive (4WD).

[0005] Conversely, the actuator device can be operated to move the sleeve in the disengagement direction. As the sleeve moves in the disengagement direction, the clutch ring connected to the sleeve moves away from the support ring, thereby disengaging the clutch ring from the support ring. This allows for two-wheel drive (2WD).

[0006] However, conventional disconnector devices have a complex operating structure that increases the overall length of the vehicle, occupies a lot of space, increases weight, and is difficult to install.When the disconnector shaft and disconnector hub are separated and the vehicle is traveling straight at high speed, the rotation of the left side gear causes the pinion gear to rotate at high speed, resulting in a high differential, which causes noise and vibration.

[0007] Furthermore, in conventional disconnector devices, the tips of the teeth on the clutch ring and support ring have a flat structure, so when the clutch ring and support ring engage, the teeth collide with each other, causing impact and resulting in a problem of the clutch ring and support ring taking a long time to engage.

[0008] [Patent Document 1] Republic of Korea Patent Publication No. 10-2017-0123869 (Published on November 9, 2017) Summary of the Invention [Problem to be solved by the invention]

[0009] In order to solve the above-mentioned problems, the present invention aims to provide a disconnector device in which a clutch ring engages with a support ring inside a case body to achieve four-wheel drive.

[0010] Another object of the present invention is to provide a disconnector device that allows smooth engagement between the clutch ring and the support ring by forming at least one inclined contact surface and one relative inclined contact surface at the tips of the teeth of the clutch ring and the support ring. [Means for solving the problem]

[0011] In order to achieve the above-mentioned object, the present invention provides a disconnector device including: a case including a case body and a cover connected to the case body; a support ring provided inside the case body; and a clutch ring having a first clutch portion provided on an outer diameter portion and a second clutch portion provided on an inner diameter portion, the clutch ring being movable toward the support ring when pressed by a sleeve, the first clutch portion always engaging with a third clutch portion provided on the inner diameter portion of the case body, and the second clutch portion being capable of engaging with a fourth clutch portion provided on one side outer diameter portion of the support ring.

[0012] In addition, the clutch ring is connected to the sleeve, and the sleeve pushes the clutch ring toward the support ring, thereby engaging the second clutch portion with the fourth clutch portion, and the disengagement operation of the sleeve pushes the clutch ring in the opposite direction from the support ring, thereby disengaging the second clutch portion and the fourth clutch portion.

[0013] In addition, at least one inclined contact surface is provided at the tip of the tooth of the second clutch portion, and at least one relative inclined contact surface is provided at the tip of the tooth of the fourth clutch portion, and when the second clutch portion and the fourth clutch portion are engaged, the inclined contact surface slides while contacting the relative inclined contact surface, thereby performing engagement.

[0014] The inclined contact surface may be provided on one side of a tip of a tooth of the second clutch portion, and the inclined contact surface may form an acute angle with the tip end of the tooth of the second clutch portion.

[0015] In addition, the relative inclined contact surface may be provided on one side of a tip of a tooth of the fourth clutch portion facing the inclined contact surface, and the relative inclined contact surface may form an acute angle with the tip end of the tooth of the fourth clutch portion.

[0016] In addition, the inclined contact surface may be provided on one side of a tip of a tooth of the second clutch portion, and the tip end of the tooth of the second clutch portion excluding the inclined contact surface may be formed as a flat surface, and the inclined contact surface may form an obtuse angle with the tip end of the tooth of the second clutch portion.

[0017] In addition, the relative inclined contact surface may be provided on one side of the tip of the tooth of the fourth clutch portion facing the inclined contact surface, and the tip end of the tooth of the fourth clutch portion excluding the relative inclined contact surface may be formed as a flat surface, and the relative inclined contact surface may form an obtuse angle with the tip end of the tooth of the fourth clutch portion.

[0018] The inclined contact surfaces may be provided on both sides of the tip of the tooth of the second clutch portion.

[0019] The relative inclined contact surfaces may be provided on both sides of the tip of the tooth of the fourth clutch portion that faces the inclined contact surfaces provided on both sides.

[0020] In addition, the tip end of the tooth of the second clutch part located between the inclined contact surfaces provided on both sides may be formed as a flat surface, and the inclined contact surface may form an obtuse angle with the tip end of the tooth of the fourth clutch part.

[0021] In addition, the tip end of the tooth of the fourth clutch part provided between the relative inclined contact surfaces provided on both sides may be formed as a flat surface, and the relative inclined contact surface may form an obtuse angle with the tip end of the tooth of the fourth clutch part.

[0022] In addition, a locking protrusion is provided on the outer diameter portion of the case body to which the sleeve is connected, and a locking surface is provided on one side of the sleeve facing the locking protrusion, and the sleeve, which moves along the outer diameter portion of the case body by driving the actuator device, can have its movement restricted by the locking surface locking onto the locking protrusion.

[0023] In addition, at least one pressure member may be provided along a surface of the sleeve facing the clutch ring, and the pressure member may pass through a through hole provided in the case body and be connected to the clutch ring provided inside the case body.

[0024] In addition, the pressure applying portion may push the clutch ring toward the support ring to engage the second clutch portion with the fourth clutch portion, or may pull the clutch ring in the opposite direction from the support ring to disengage the second clutch portion from the fourth clutch portion.

[0025] In addition, the pressure member may be locked by a locking member attached inside the case body and thus movement may be restricted when the second clutch member and the fourth clutch member are disengaged. [Effects of the Invention]

[0026] In the present invention, while the first clutch portion is constantly engaged with the third clutch portion of the case body, the clutch ring is pushed toward the support ring by the operation of the sleeve, causing the second clutch portion to engage with the fourth clutch portion of the support ring, thereby enabling four-wheel drive.

[0027] In addition, when the vehicle is driven in two-wheel drive mode by disengaging the second clutch unit and the fourth clutch unit, in the case of an auxiliary drive wheel coasting, the support ring that supports the differential gear set including two side gears and four pinion gears rotates together with the auxiliary drive wheel, thereby solving the noise problem caused by the conventional high differential.

[0028] Furthermore, the present invention can significantly reduce the overall length, which not only reduces the weight but also significantly improves packaging mountability.

[0029] In addition, the present invention forms at least one inclined contact surface and one relative inclined contact surface at the tips of the teeth of the second clutch portion of the clutch ring and the teeth of the fourth clutch portion of the support ring, thereby enabling smooth engagement between the second clutch portion and the fourth clutch portion.

[0030] In addition, the present invention solves the problem that the tips of the teeth of the clutch ring and the teeth of the support ring have a flat structure, which causes the teeth of the clutch ring and the teeth of the support ring to collide with each other during engagement, generating impact and lengthening the engagement time of the clutch ring and the support ring.

[0032] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. First, when assigning reference numerals to components in each drawing, it should be noted that the same components are assigned the same numerals as possible when appearing in other drawings. Furthermore, when describing the present invention, if a detailed description of related well-known structures or functions is deemed to obscure the gist of the present invention, such a detailed description will be omitted. Furthermore, while preferred embodiments of the present invention will be described below, the technical concept of the present invention is not limited thereto and can be modified and implemented in various ways by those skilled in the art.

[0033] The present invention can be applied to electric vehicles (battery electric vehicles, EVs), as well as internal combustion engine vehicles (ICEs) and hybrid electric vehicles (HEVs).

[0034] Figure 1 is a perspective view of a disconnector device according to a preferred embodiment of the present invention, Figure 2 is a view showing a differential gear set assembled inside a support ring according to a preferred embodiment of the present invention, Figure 3 is an exploded perspective view of a disconnector device according to a preferred embodiment of the present invention, and Figure 4 is a side cross-sectional view of a disconnector device according to a preferred embodiment of the present invention.

[0035] As shown in Figures 1 to 4, the present invention can include a case consisting of a case body 111 and a cover 112 connected to the case body 111, a support ring 140 provided inside the case body 111, a differential gear set consisting of a side gear SG attached inside the support ring 140 and a pinion gear PG meshing with the side gear SG, a clutch ring 130 meshing with the support ring 140 inside the case body 111, and a sleeve 120 connected to the clutch ring 130.

[0036] When the actuator device 150 is driven, the sleeve 120 connected to the actuator device 150 pushes the clutch ring 130 toward the support ring 140, so that the clutch ring 130 and the support ring 140 can be engaged with each other.

[0037] A locking protrusion 111b may be provided on the case body 111. The locking protrusion 111b may be provided on an outer diameter portion of the case body 111 to which the sleeve 120 is coupled.

[0038] When the actuator device 150 is driven, the sleeve 120 provided on the outer diameter portion of the case body 111 can move along the outer diameter portion of the case body 111 toward the support ring 140 .

[0039] The sleeve 120 may be provided with a locking surface 121. The locking surface 121 may be provided on one side of the sleeve 120 facing the locking protrusion 111b. The locking surface 121 is locked to the locking protrusion 111b, thereby restricting the movement of the sleeve 120.

[0040] The sleeve 120 may be provided with a pressing portion 122. At least one pressing portion 122 may be provided along a surface of the sleeve 120 facing the clutch ring 130. The pressing portion 122 may pass through a through-hole 111c provided in the case body 111 and be positioned inside the case body 111. The pressing portion 122 may be connected to the clutch ring 130 inside the case body 111.

[0041] The pressure member 122 and the clutch ring 130 may be connected by various known connection structures such as bolt connection.

[0042] The clutch ring 130 may be provided with a first clutch portion 131 provided on an outer diameter portion and a second clutch portion 132 provided on an inner diameter portion.

[0043] A third clutch portion 111a may be provided on an inner diameter portion of the case body 111. A fourth clutch portion 144 may be provided on an outer diameter portion of one side of the support ring 140.

[0044] The first clutch portion 131 of the clutch ring 130 can be constantly engaged with the third clutch portion 111 a of the case body 111 .

[0045] In situations where four-wheel drive driving performance, such as acceleration, or regenerative braking is required, the second clutch portion 132 of the clutch ring 130 can engage with the fourth clutch portion 144 of the support ring 140.

[0046] For example, the second clutch portion 132 of the clutch ring 130 can be disengaged from the fourth clutch portion 144 of the support ring 140 in two-wheel drive, and can be engaged with the fourth clutch portion 144 of the support ring 140 in four-wheel drive.

[0047] The sleeve 120 is coupled to the outer diameter portion of the case body 111 and can move along the outer diameter portion of the case body 111 .

[0048] By operating the actuator device 150, the sleeve 120 connected to the actuator device 150 can move in an engagement direction. As the sleeve 120 moves in the engagement direction, the clutch ring 130 connected to the sleeve 120 moves toward the support ring 140, so that the teeth 132a of the second clutch portion 132 of the clutch ring 130 can be brought into an interlocking state in which they engage with the teeth 144a of the fourth clutch portion 144 of the support ring 140. This allows four-wheel drive (4WD) to be achieved.

[0049] At this time, the locking surface 121 of the sleeve 120 is locked by the locking projection 111b of the case body 111, so that the sleeve 120 does not move any further in the direction of the support ring 140 and can be stopped.

[0050] Conversely, the sleeve 120 can be moved in the disengagement direction by operation of the actuator device 150. As the sleeve 120 moves in the disengagement direction, the second clutch portion 132 of the clutch ring 130 and the fourth clutch portion 144 of the support ring 140, which are connected to the sleeve 120, can be disengaged. This allows two-wheel drive (2WD) to be achieved.

[0051] When the second clutch portion 132 and the fourth clutch portion 144 of the sleeve 120 are disengaged, the pressure member 122 may be locked by a locking member ST attached to the inside of the case body 111, and the movement of the pressure member 122 may be restricted. For example, the locking member ST may be a stop ring.

[0052] FIG. 5 is a diagram showing a schematic view of the teeth of the clutch ring and the support ring according to the first embodiment.

[0053] 3 and 5, teeth 132a of the second clutch portion 132 of the clutch ring 130 may be formed along an inner diameter portion. Teeth 144a of the fourth clutch portion 144 of the support ring 140 may be formed along an outer diameter portion on one side facing the second clutch portion 132.

[0054] The second clutch part 132 may have an inclined contact surface 132b on one side of the tip of the tooth 132a.

[0055] The inclined contact surface 132b may be configured as an inclined surface that forms an acute angle AA with the tip end portion 132c of the tooth 132a of the second clutch portion 132.

[0056] A relative inclined contact surface 144b may be provided on one side of the tip of the tooth 144a of the fourth clutch portion 144 of the support ring 140, which faces the inclined contact surface 132b.

[0057] The relative inclined contact surface 144b may be configured as an inclined surface that forms an acute angle AA with the tip end portion 144c of the tooth 144a of the fourth clutch component 144.

[0058] When the second clutch portion 132 and the fourth clutch portion 144 are engaged, the clutch ring 130 moves toward the support ring 140, allowing the inclined contact surface 132b of the tooth 132a of the second clutch portion 132 to come into contact with the relative inclined contact surface 144b of the tooth 144a of the fourth clutch portion 144.

[0059] The teeth 132a of the second clutch part 132 can be easily inserted between the teeth 144a of the fourth clutch part 144 by sliding along the relative inclined contact surface 144b while the inclined contact surface 132b is in contact with the relative inclined contact surface 144b of the teeth 144a of the fourth clutch part 144.

[0060] The inclined contact surface 132b and the relative inclined contact surface 144b allow the second clutch component 132 and the fourth clutch component 144 to mesh smoothly.

[0061] FIG. 6 is a diagram showing a schematic view of teeth of a clutch ring and a support ring according to the second embodiment.

[0062] 3 and 6, teeth 132a of the second clutch portion 132 of the clutch ring 130 may be formed along an inner diameter portion. Teeth 144a of the fourth clutch portion 144 of the support ring 140 may be formed along an outer diameter portion on one side facing the clutch ring 130.

[0063] The second clutch part 132 may have an inclined contact surface 132b on one side of the tip of the tooth 132a.

[0064] The tip end 132c of the tooth 132a of the second clutch part 132, excluding the inclined contact surface 132b, may be formed as a flat surface.

[0065] The tip end 132c of the tooth 132a of the second clutch part 132, which is formed as a flat surface, and the side surface of the adjacent tooth 132a of the second clutch part 132 may form a right angle.

[0066] The inclined contact surface 132b may be configured as an inclined surface that forms an obtuse angle OA with the tip end portion 132c of the tooth 132a of the second clutch portion 132.

[0067] A relative inclined contact surface 144b may be provided on one side of the tip of the tooth 144a of the fourth clutch part 144, which faces the inclined contact surface 132b.

[0068] The tip end portion 144c of the tooth 144a of the fourth clutch part 144, excluding the relative inclined contact surface 144b, may be formed as a flat surface.

[0069] The relative inclined contact surface 144b may be configured as an inclined surface that forms an obtuse angle OA with the tip end portion 144c of the tooth 144a of the fourth clutch component 144.

[0070] When the second clutch portion 132 and the fourth clutch portion 144 are engaged, the second clutch portion 132 moves toward the fourth clutch portion 144, allowing the inclined contact surface 132b of the tooth 132a of the second clutch portion 132 to come into contact with the relative inclined contact surface 144b of the fourth clutch portion 144.

[0071] The teeth 132a of the second clutch part 132 can be easily inserted between the teeth 144a of the fourth clutch part 144 by sliding along the relative inclined contact surface 144b while the inclined contact surface 132b is in contact with the relative inclined contact surface 144b of the fourth clutch part 144.

[0072] The inclined contact surface 132b and the relative inclined contact surface 144b allow the second clutch component 132 and the fourth clutch component 144 to mesh smoothly.

[0073] FIG. 7 is a diagram showing a schematic view of teeth of a clutch ring and a support ring according to a third embodiment.

[0074] 3 and 7, teeth 132a of the second clutch portion 132 of the clutch ring 130 may be formed along an inner diameter portion. Teeth 144a of the fourth clutch portion 144 of the support ring 140 may be formed along an outer diameter portion on one side facing the second clutch portion 132.

[0075] The second clutch part 132 may have inclined contact surfaces 132b on both sides of the tip of the tooth 132a.

[0076] Relative inclined contact surfaces 144b may be provided on both sides of the tip of the tooth 144a of the fourth clutch part 144, which faces the inclined contact surfaces 132b provided on both sides.

[0077] The tip end 132c of the tooth 132a of the second clutch part 132 located between the inclined contact surfaces 132b provided on both sides may be formed as a flat surface.

[0078] The inclined contact surface 132b may be configured as an inclined surface that forms an obtuse angle OA with the tip end portion 132c of the tooth 132a of the second clutch portion 132 that is configured as a flat surface.

[0079] The tip end 144c of the tooth 144a of the fourth clutch part 144 provided between the relative inclined contact surfaces 144b provided on both sides may be formed as a flat surface.

[0080] The relative inclined contact surface 144b can form an obtuse angle OA with the tip end portion 144c of the tooth 144a of the fourth clutch component 144.

[0081] When the second clutch part 132 and the fourth clutch part 144 are engaged, the clutch ring 130 moves toward the support ring 140, allowing at least one of the inclined contact surfaces 132b on either side of the tooth 132a of the second clutch part 132 to come into contact with the relative inclined contact surface 144b of the opposing fourth clutch part 144.

[0082] The teeth 132a of the second clutch part 132 can be easily inserted between the teeth 144a of the fourth clutch part 144 by sliding along the relative inclined contact surface 144b while the inclined contact surface 132b is in contact with the relative inclined contact surface 144b of the teeth 144a of the fourth clutch part 144.

[0083] The inclined contact surface 132b and the relative inclined contact surface 144b allow the second clutch component 132 and the fourth clutch component 144 to mesh smoothly.

[0084] As described above, the present invention enables four-wheel drive by pushing the clutch ring toward the support ring due to the operation of the sleeve while the first clutch portion is constantly engaged with the third clutch portion of the case body, thereby engaging the second clutch portion with the fourth clutch portion of the support ring. Furthermore, when driving in two-wheel drive mode by disengaging the second and fourth clutch portions, the support ring supporting the differential gear set including two side gears and four pinion gears rotates together with the coasting auxiliary drive wheel, thereby solving the noise problem caused by high differential gears in the conventional vehicle. Furthermore, the present invention significantly reduces the overall length, thereby reducing weight and significantly improving packaging and installation. Furthermore, the present invention provides at least one inclined contact surface and one relative inclined contact surface at the tips of the teeth of the second clutch portion of the clutch ring and the teeth of the fourth clutch portion of the support ring, thereby enabling smooth engagement between the second and fourth clutch portions. In addition, the present invention solves the problem that the tips of the teeth of the clutch ring and the teeth of the support ring have a flat structure, which causes the teeth of the clutch ring and the teeth of the support ring to collide with each other during engagement, generating impact and lengthening the engagement time of the clutch ring and the support ring.
