Description

Technical Field

[0001] The invention relates to a structure of a clutch ring and a support ring installed in a disconnect device. Background Art

[0002] Typically, the disconnect device is installed on the differential assembly to separate or connect the differential shaft according to the driving conditions and to minimize unnecessary power loss by switching between two-wheel drive (2WD) and four-wheel drive (4WD).

[0003] The disconnect device may include: a differential case, a support ring installed inside the differential case, a pinion installed inside the support ring, a left side shaft gear and a right side shaft gear meshed with the pinion gear, and a clutch ring meshed with the support ring.

[0004] By operating the actuator device, the sleeve connected to the actuator device can be moved in the meshing direction. When the sleeve moves in the meshing direction, the clutch ring connected to the sleeve moves in the direction of the support ring, and the teeth of the clutch ring are meshed with the teeth of the support ring. In this way, four-wheel drive (4WD) can be achieved.

[0005] On the contrary, by operating the actuator device, the sleeve can be moved in the disengagement direction. As the sleeve moves in the disengagement direction, the clutch ring connected to the sleeve is separated from the support ring, and the meshing state of the clutch ring and the support ring can be released. Thus, two-wheel drive (2WD) can be achieved.

[0006] However, in the existing disconnect device, since the front ends of the teeth of the clutch ring and the support ring are planar structures, there is a problem that when they are engaged, the teeth of the clutch ring and the support ring collide with each other and vibrate, resulting in a longer engagement time.

When the clutch ring is meshed with the support ring, the inclined contact surface slides in contact with the relatively inclined contact surface and meshes at the same time.

[0012] Furthermore, the clutch ring tooth may have the inclined contact surface on the front end side thereof, and the inclined contact surface may form an acute angle with the tip of the clutch ring tooth.

[0013] Furthermore, the relatively inclined contact surface may be provided on the front end side of the tooth of the support ring opposite to the inclined contact surface, and the relatively inclined contact surface may form an acute angle with the tip of the tooth of the support ring.

[0014] Moreover, the clutch ring tooth may have the inclined contact surface on the front end side thereof, the tip of the clutch ring tooth except the inclined contact surface may be formed as a plane, and the inclined contact surface may form an obtuse angle with the tip of the clutch ring tooth.

[0015] Moreover, it may be that the relatively inclined contact surface is provided on the front end side of the tooth of the support ring opposite to the inclined contact surface, the tip of the tooth of the support ring except the relatively inclined contact surface is formed as a plane, and the relatively inclined contact surface forms an obtuse angle with the tip of the tooth of the support ring.

[0016] Furthermore, the clutch ring may have the inclined contact surfaces on both sides of the front ends of the teeth.

[0017] Furthermore, the relatively inclined contact surfaces may be provided on both sides of the front end of the teeth of the support ring opposite to the inclined contact surfaces provided on both sides.

[0018] Furthermore, the tip of the tooth of the clutch ring located between the inclined contact surfaces provided on both sides may be formed into a plane, and the inclined contact surface and the tip of the tooth of the clutch ring may form an obtuse angle.

[0019] Furthermore, the tip of the tooth of the support ring located between the relatively inclined contact surfaces provided on both sides may be formed into a plane, and the relatively inclined contact surface and the tip of the tooth of the support ring may form an obtuse angle.

[0020] Furthermore, the teeth of the clutch ring may be formed along an inner diameter portion of the support ring, and the teeth of the support ring may be formed along an outer diameter portion of the clutch ring.

[0021] Furthermore, the clutch ring and the support ring may be installed inside a housing of the disconnect device, and the clutch ring may be engaged with the support ring while the sleeve moved toward the support ring by operating the actuator device.

[0022] Effects of the Invention

[0023] In the present invention, at least one inclined contact surface and a relatively inclined contact surface are formed at the front ends of the teeth of the clutch ring and the support ring, so that the clutch ring and the support ring can be smoothly meshed.

[0024] In addition, the present invention can also solve the problem that in the existing disconnection device, since the front ends of the teeth of the clutch ring and the support ring are planar structures, when they are engaged, the teeth of the clutch ring and the support ring collide with each other and vibrate, resulting in a longer engagement time of the clutch ring and the support ring.

[0034] Below, a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings. First, it should be noted that when marking the components of each drawing, the same components should be marked with the same reference numerals as much as possible even in different drawings. In addition, when describing the present invention, if it is determined that the specific description of the relevant known structure or function will make the gist of the present invention unclear, the detailed description will be omitted. In addition, although the following describes a preferred embodiment of the present invention, the technical concept of the present invention is not limited to or restricted thereto, and can be modified and implemented in various ways by ordinary technicians in the field.

[0035] Figure 1 1 is a diagram showing a clutch ring and a support ring installed on a disconnect device according to a preferred embodiment of the present invention.

[0036] like Figure 1 As shown, the disconnect device 100 may include: a housing 110, a support ring 140 installed inside the housing 110, a pinion (not shown) installed inside the support ring 140, left and right side half-shaft gears (not shown) meshing with the pinion (not shown), and a clutch ring 130 meshing with the support ring 140.

[0037] When the actuator device (not shown) is operated, the sleeve 120 connected to the actuator device (not shown) can move toward the support ring 140 .

[0038] When the sleeve 120 moves, the clutch ring 130 connected to the sleeve 120 can move toward the support ring 140. The surface of the sleeve 120 facing the clutch ring 130 can have a connecting portion 121 connected to the clutch ring 130. The connecting portion 121 can be composed of a plurality of parts.

[0039] The clutch ring 130 can move toward the support ring 140 and mesh with the support ring 140 .

[0040] The sleeve 120 connected to the actuator device (not shown) can move in the meshing direction through the operation of the actuator device (not shown). When the sleeve 120 moves in the meshing direction, the clutch ring 130 connected to the sleeve 120 moves toward the direction of the support ring 140, and the teeth 131a of the clutch ring 130 and the teeth 141a of the support ring 140 are meshed (interloking). In this way, four-wheel drive (4WD) can be achieved.

[0041] On the contrary, the sleeve 120 can be moved in the disengagement direction by the operation of the actuator device (not shown). When the sleeve 120 moves in the disengagement direction, the clutch ring 130 connected to the sleeve 120 is separated from the support ring 140, and the meshing state of the clutch ring 130 and the support ring 140 can be released. Thus, two-wheel drive (2WD) can be achieved.

[0042] Figure 2 is an enlarged view of a clutch ring and a support ring according to a first embodiment of the present invention, Figure 3 It is schematically shown Figure 2 Diagram of the teeth of the clutch ring and support ring.

[0043] like Figure 2 and Figure 3 As shown, in the first embodiment of the present invention, the teeth 131a of the clutch ring 130 may be formed along the inner diameter portion 131 toward the support ring 140. The teeth 141a of the support ring 140 may be formed along the outer diameter portion 141 toward the clutch ring 130. When the clutch ring 130 and the support ring 140 are engaged, the outer diameter portion 141 of the support ring 140 may be inserted into the inner diameter portion 131 of the clutch ring 130.

[0044] The clutch ring 130 may have an inclined contact surface 131 b at the front end side of the teeth 131 a .

[0045] The inclined contact surface 131 b of the clutch ring 130 may be formed of an inclined surface forming an acute angle AA with the tip 131 c of the tooth 131 a of the clutch ring 130 .

[0046] The support ring 140 may have a relatively inclined contact surface 141 b at a front end side of the teeth 141 a opposite to the inclined contact surface 131 b of the clutch ring 130 .

[0047] The relatively inclined contact surface 141 b of the support ring 140 may be composed of an inclined surface forming an acute angle AA with the tip 141 c of the tooth 141 a .

[0048] When the clutch ring 130 and the support ring 140 are meshed, the clutch ring 130 moves toward the support ring 140 , and the inclined contact surface 131 b of the teeth 131 a of the clutch ring 130 may contact the relatively inclined contact surface 141 b of the support ring 140 .

[0049] When the teeth 131a of the clutch ring 130 slide along the relatively inclined contact surface 141b while the inclined contact surface 131b contacts the relatively inclined contact surface 141b of the support ring 140, the teeth 131a can be easily inserted between the teeth 141a of the support ring 140. Thus, the clutch ring 130 and the support ring 140 can be smoothly meshed.

[0050] Figure 4 is an enlarged view of a clutch ring and a support ring according to a second embodiment of the present invention, Figure 5 It is schematically shown Figure 4 Diagram of the teeth of the clutch ring and support ring.

[0051] like Figure 4 and Figure 5 As shown, in the second embodiment of the present invention, the teeth 131a of the clutch ring 130 may be formed along the inner diameter portion 131 toward the support ring 140. The teeth 141a of the support ring 140 may be formed along the outer diameter portion 141 toward the clutch ring 130. When the clutch ring 130 and the support ring 140 are engaged, the outer diameter portion 141 of the support ring 140 may be inserted into the inner diameter portion 131 of the clutch ring 130.

[0052] The clutch ring 130 may have an inclined contact surface 131 b at the front end side of the teeth 131 a .

[0053] The tip 131c of the tooth 131a of the clutch ring 130 may be formed as a flat surface except for the inclined contact surface 131b.

[0054] The tip 131 c of the tooth 131 a of the clutch ring 130 formed as a plane may form a right angle with a side surface of the tooth 131 a of the adjacent clutch ring 130 .

[0055] The inclined contact surface 131 b may be formed of an inclined surface forming an obtuse angle OA with the tip 131 c of the tooth 131 a of the clutch ring 130 .

[0056] The support ring 140 may have a relatively inclined contact surface 141 b at a front end side of the teeth 141 a opposite to the inclined contact surface 131 b.

[0057] The tip 141c of the tooth 141a of the support ring 140 may be formed as a flat surface except for the relatively inclined contact surface 141b.

[0058] The relatively inclined contact surface 141 b may be composed of an inclined surface forming an obtuse angle OA with the tip 141 c of the tooth 141 a of the support ring 140 .

[0059] When the clutch ring 130 and the support ring 140 are meshed, the clutch ring 130 moves toward the support ring 140 , and the inclined contact surface 131 b of the teeth 131 a of the clutch ring 130 may contact the relatively inclined contact surface 141 b of the support ring 140 .

[0060] When the teeth 131a of the clutch ring 130 slide along the relatively inclined contact surface 141b while the inclined contact surface 131b contacts the relatively inclined contact surface 141b of the support ring 140, they can be easily inserted between the teeth 141a of the support ring 140. Thus, the clutch ring 130 and the support ring 140 can be smoothly meshed.

[0061] In addition, the clutch ring 130 may have an extension portion 132 connected to the sleeve 120 on the surface facing the sleeve 120. The extension portion 132 may be composed of a plurality of extension portions 132. The extension portion 132 may be connected to the connection portion 121 of the sleeve 120.

[0062] Figure 6 is an enlarged view of a clutch ring and a support ring according to a third embodiment of the present invention, Figure 7 It is schematically shown Figure 6 Diagram of the teeth of the clutch ring and support ring.

[0063] like Figure 6 and Figure 7 As shown, in the third embodiment of the present invention, the teeth 131a of the clutch ring 130 may be formed along the inner diameter portion 131 toward the support ring 140. The teeth 141a of the support ring 140 may be formed along the outer diameter portion 141 toward the clutch ring 130. When the clutch ring 130 and the support ring 140 are engaged, the outer diameter portion 141 of the support ring 140 may be inserted into the inner diameter portion 131 of the clutch ring 130.

[0064] The clutch ring 130 may have inclined contact surfaces 131 b on both sides of the front end of the teeth 131 a.

[0065] The supporting ring 140 may have oppositely inclined contact surfaces 141 b at both sides of the front end of the teeth 141 a opposite to the inclined contact surfaces 131 b provided at both sides.

[0066] The tip 131c of the tooth 131a of the clutch ring 130 located between the inclined contact surfaces 131b provided on both sides may be formed as a flat surface.

[0067] The inclined contact surface 131 b may be formed of an inclined surface forming an obtuse angle OA with the tip 141 c of the tooth 131 a of the clutch ring 130 formed as a plane.

[0068] The tip 141c of the tooth 141a of the support ring 140 located between the oppositely inclined contact surfaces 141b provided on both sides may be formed as a flat surface.

[0069] The relatively inclined contact surface 141 b may form an obtuse angle OA with the tip 141 c of the tooth 141 a of the support ring 140 .

[0070] When the clutch ring 130 and the support ring 140 are meshed, the clutch ring 130 moves toward the support ring 140 , and one of the inclined contact surfaces 131 b on both sides of the teeth 131 a of the clutch ring 130 can contact the relatively inclined contact surface 141 b of the opposite support ring 140 .

[0071] When the teeth 131a of the clutch ring 130 slide along the relatively inclined contact surface 141b while the inclined contact surface 131b contacts the relatively inclined contact surface 141b of the support ring 140, they can be easily inserted between the teeth 141a of the support ring 140. Thus, the clutch ring 130 and the support ring 140 can be smoothly meshed.

[0072] In addition, the clutch ring 130 may have an extension portion 132 connected to the sleeve 120 on the surface facing the sleeve 120. The extension portion 132 may be composed of a plurality of extension portions. The extension portion 132 may be connected to the connection portion 121 of the sleeve 120.

[0073] As described above, in the present invention, by forming at least one inclined contact surface and a relatively inclined contact surface at the front ends of the teeth of the clutch ring and the support ring, the clutch ring and the support ring can be smoothly meshed. In addition, the present invention can also solve the problem that since the front ends of the teeth of the existing clutch ring and the support ring are planar structures, when the teeth of the clutch ring and the support ring collide with each other, vibration is generated, resulting in a longer meshing time of the teeth between the clutch ring and the support ring.

[0074] The above description is only used to exemplify the technical spirit of the present invention, and ordinary technicians in the field to which the present invention belongs can make various modifications, changes and substitutions without departing from the essential features of the present invention.
