Description

Technical field

[0001] The present invention relates to an interrupting device (e.g. a disconnecting device) that switches from a four-wheel drive to a two-wheel drive. Background technology

[0002] In general, a breaker device refers to a device that is mounted in a differential arrangement and is capable of minimizing unnecessary power loss by switching between two-wheel drive (2WD) and four-wheel drive (4WD) by engaging or disengaging a differential shaft depending on a driving situation (e.g., engaging or disengaging the clutch).

[0003] Fig. Figure 1 is a view depicting an interrupter device in the related technology. Referring to Fig. Figure 1 includes the breaker device: a differential assembly 1, a breaker shaft 1c connected to a right differential side gear 1b provided in a differential housing 1a, a breaker hub 1d connected to a right vehicle wheel (not shown), and a breaker sleeve 1e configured to allow or block power transmission between the breaker shaft 1c and the breaker hub 1d. An end gear 1h may be coupled to the differential housing 1a.

[0004] A left differential side gear 1i is provided in the differential housing 1a and, together with the right differential side gear 1b, defines a pair of side gears. The right differential side gear 1b and the left differential side gear 1i can mesh with four differential pinions 1j.

[0005] When a ball screw shaft 2b is rotated by the operation of a motor (e.g., an electric motor) 2a of an actuating device 2, a ball screw nut 2c coupled to the ball screw shaft 2b moves along a guide rail 2d. As the ball screw nut 2c moves, a fork 2e integrated with the ball screw nut 2c can move the sleeve 1e in a connecting or disconnecting direction.

[0006] When the separating sleeve 1e engages simultaneously with a claw tooth part 1f of the separating shaft 1c and a claw tooth part 1g of the separating hub 1d, an input part (not shown), such as an electric motor or an internal combustion engine, and an output part (not shown), such as a vehicle wheel, are dynamically connected, so that a four-wheel drive (4WD) can be implemented.

[0007] When the separating sleeve 1e moves towards the separating hub 1d and the claw tooth part 1f of the separating shaft 1c and the claw tooth part 1g of the separating hub 1d are disengaged from each other, (then) the power transmission between the input part, such as the electric motor or the internal combustion engine, and the output part, such as the vehicle wheel, is blocked, so that a two-wheel drive (2WD) can be implemented.

[0008] However, in the interrupter device used in the related technology, the overall length and space (e.g., the space requirement) of the vehicle (e.g., within the vehicle) increase excessively due to the complex operating structure, in which the ball screw shaft, the fork, and the separating sleeve are jointly actuated by the operation of the electric motor, and the separating shaft and the separating hub are connected by the operation of the separating sleeve. This results in disadvantages regarding the weight and ease of assembly of the vehicle (e.g., within the vehicle). Furthermore, in the case of a two-wheel drive implemented by disconnecting an auxiliary drive gear of a four-wheel drive vehicle, the final gear is stopped when the rotation of the input part is stopped, and a high differential occurs (e.g.,A high speed difference occurs when the differential pinion is rotated at high speed by the rotation of the left differential side gear while the vehicle is traveling straight ahead at high speed with the separating shaft and hub disengaged. This causes noise and vibration. Document relating to the technology used:

[0010] DE 197 16 386 A1 discloses a compensating device.

[0011] KR 10 1 530 485 B1 discloses a power switching device of a transmission housing of a four-wheeled vehicle. Explanation of the invention

[0012] The present invention is based on the objective of providing an interrupter device (e.g. a disconnecting device) in which a pinion can be provided in the interrupter device and can engage with a side gear and in which a high differential (e.g. a large speed difference) can be prevented by means of a retaining ring / support ring which is connected to or disconnected from power (e.g. a power supply, e.g. a power source) by means of a clutch ring.

[0013] Furthermore, the present invention is based on the objective of providing an interrupting device (e.g. a disconnecting device) that is able to improve the assembly properties and versatility by modularizing an actuating device.

[0014] To solve this problem, the present invention provides an interrupter device (e.g., a disconnecting device) comprising: a retaining ring mounted in a housing, which has a pinion mounted in the retaining ring and configured to engage with a first lateral gear, wherein the retaining ring has a first claw tooth part (e.g., a first claw coupling part) provided on a surface (e.g., of the retaining / support ring) facing the first lateral gear; and a coupling ring comprising a second claw tooth part (e.g., a second claw coupling part) provided on a surface (e.g., of the coupling ring) facing the retaining ring, wherein the second claw tooth part is configured to engage with the first claw tooth part.to get stuck), and a sleeve connected to an actuating device and configured to move in an in-engagement direction (e.g., a retraction direction) or an out-engagement direction (e.g.,a disengagement direction) wherein the sleeve is connected to the clutch ring and is configured to push the clutch ring in one direction towards the retaining ring or to pull the clutch ring in a direction opposite to the retaining ring, wherein the retaining ring has a through hole provided in one outer diameter section thereof and has a coupling hole formed in the other face thereof, a coupling pin is coupled to the pinion while penetrating the through hole, and a fastening pin is coupled to the coupling pin while penetrating the coupling hole, wherein an inner ring is coupled in the retaining ring, the pinion is arranged between the retaining ring and the inner ring, and the retaining ring, the pinion, and the inner ring are coupled by means of the coupling pin.

[0015] In the case of a four-wheel drive, the sleeve can push the clutch ring in the direction towards the retaining ring to allow the second claw tooth part to engage with the first claw tooth part (e.g., disengage), and in the case of a two-wheel drive, the sleeve can pull the clutch ring in the opposite direction to the retaining ring to allow the second claw tooth part to separate from the first claw tooth part and be out of engagement with it (e.g., disengage).

[0016] The actuating device may comprise: a housing, a motor (e.g., an electric motor, e.g., a servo motor) coupled (e.g., connected) to the housing, a ball screw shaft arranged in the housing and rotatably held on a retaining element (e.g., support element), wherein the ball screw shaft is connected to the motor, a transmission nut coupled to the ball screw shaft and configured to move along the ball screw shaft while guided by a guide rail mounted in the housing, and a fork integrated with the transmission nut and extending towards the sleeve through an opening section in the housing, wherein the fork is coupled to surround an outer diameter section of the sleeve.

[0017] A sealing element can be coupled to a coupling surface of the housing to which the motor is coupled.

[0018] The coupling ring can have multiple leg parts, the housing can have holes that correspond to the leg parts, and the leg parts can be exposed (e.g., revealed) through the holes.

[0019] An outer diameter section of the leg part can be configured as an inclined surface, and an inner diameter section of the housing, into which the outer diameter section of the leg part is inserted and with which the outer diameter section of the leg part is in contact, can be configured as an inclined surface.

[0020] The holding element can be a bearing (e.g. a roller bearing, e.g. a ball bearing).

[0021] The sealing element can be an O-ring.

[0022] According to the present invention, when the interrupter system (e.g. the interrupter device) is disengaged and the auxiliary drive wheels are free-running in the two-wheel drive mode of the vehicle (e.g. they rotate without being driven), the retaining ring / support ring that holds (e.g. supports) the differential gear set, which has the two side gears and the four pinions, rotates, making it possible to solve the problem of noise caused by a high differential (e.g. a high speed difference) in the related technology.

[0023] According to the present invention, the (e.g., electrical) current is / will only be applied to the motor when the clutch ring is engaged (e.g., in engagement), which makes it possible to minimize power consumption.

[0024] According to the present invention, the actuating device is modularized, which makes it possible to ensure assembly properties (e.g., mounting properties), simplify repair, and reduce a defect rate (e.g., error rate).

[0025] The present invention can significantly reduce the overall length, thereby reducing the weight and significantly improving the packaging assembly (e.g., the ease of assembly).

[0026] The present invention can eliminate a component, such as a separating shaft, in the related technology and reduce the number of components by modularizing the actuating device, which offers advantages in terms of spatial properties, weight and cost.

[0027] The present invention can simplify the assembly process by modularizing the actuating device.

[0028] According to the present invention, since the actuating device is modular, the actuating device can be installed in any reduction gear as long as there is sufficient space to mount the clutch ring and the retaining ring / support ring, which makes it possible to reduce the development time and provide a high degree of versatility.

[0033] The present invention can be used in electric vehicles (EV (from English "electric vehicles"), battery electric vehicles), internal combustion engine (ICE, from English "internal combustion engine") vehicles (e.g. combustion engine vehicles), hybrid electric vehicles (HEV, from English "hybrid electric vehicles") and the like.

[0034] Fig. Figure 2 is a perspective view of the interrupter device according to an exemplary embodiment of the present invention. Fig. Figure 3 is a perspective exploded view of the interrupter device according to the exemplary embodiment of the present invention, and Fig. Figure 4 is a cross-sectional side view of the interrupter device according to the exemplary embodiment of the present invention.

[0035] As in Fig. 2 to Fig. As shown in Figure 4, the present invention comprises: a retaining ring / support ring 120 mounted in a housing 110, a coupling ring 130 arranged in the housing 110 and configured to engage with the retaining ring / support ring 120, and a sleeve 150 configured to move the coupling ring 130 in an engagement or disengagement direction (e.g., an engagement or disengagement direction).

[0036] A final gear 190 can be coupled to an outer section of the housing 110. The power of an input component (not shown), such as an electric motor or an internal combustion engine, can be transmitted through the final gear 190. The power transmitted to the final gear 190 can be transferred to the housing 110.

[0037] For example, the housing 110 can comprise a first housing 111 and a second housing 112, which is coupled to the first housing 111. The first housing 111 and the second housing 112 can be coupled to each other by means of a coupling element, such as a screw (e.g., a bolt).

[0038] A pinion 143 is mounted in the retaining / supporting ring 120. The pinion 143 engages with a pair of first and second side gears 141 and 142. The pinion 143 can be provided as a plurality of pinions. For example, four pinions 143 can be mounted in the retaining / supporting ring 120.

[0039] The retaining / support ring 120 has a first claw tooth section (e.g., a first claw part, e.g., a first claw coupling section) 121. The first claw tooth section 121 can be provided on (e.g., on) a surface of the retaining / support ring 120 that faces the first lateral gear 141. The first lateral gear 141 can engage with a second claw tooth section (e.g., a second claw part, e.g., a second claw coupling section) 131 of the coupling ring 130.

[0040] The retaining / supporting ring 120 has a through hole 122 and a coupling hole 123 (e.g., these are formed within it). The through hole 122 is provided in one outer diameter section of the retaining / supporting ring 120. The coupling hole 123 is formed in the other surface of the retaining / supporting ring 120.

[0041] A coupling pin 160 can be coupled to pass through the through-hole 122 to reach a center (e.g., a middle) of the pinion 143. A fastening pin 170 can be coupled to pass through the coupling pin 160 through the coupling hole 123.

[0042] An inner ring 180 is coupled in the retaining / supporting ring 120. The pinion 143 is arranged between the retaining / supporting ring 120 and the inner ring 180. The retaining / supporting ring 120, the pinion 143, and the inner ring 180 are coupled by means of the coupling pin 160.

[0043] The second claw tooth part 131 can be positioned on (e.g., on) a surface of the coupling ring 130 that faces the retaining / support ring 120, and the second claw tooth part 131 can engage with the first claw tooth part 121. The coupling ring 130 can be moved by means of the sleeve 150.

[0044] The clutch ring 130 and the sleeve 150 can be assembled (e.g., joined together) by screwing or welding them together to form a single body (e.g., into one) and can be rotated together with the housing 110 by being synchronized with the housing 110.

[0045] The coupling ring 130 can have a plurality of leg parts 132. For example, the coupling ring 130 can have four leg parts 132.

[0046] Four holes 111a can be formed in the first housing 111 and correspond to the four leg parts 132. The four leg parts 132 can be exposed through the holes 111a.

[0047] An outer diameter section of the leg part 132 is inserted (e.g., fitted) into an inner diameter section of the first housing 111 and assembled (e.g., mounted) therein. The outer diameter section of the leg part 132 and the inner diameter section of the first housing 111 can each have an inclined surface S.

[0048] A fork 270 of an actuating device 200 can be coupled to an outer diameter section of the sleeve 150. The sleeve 150 can be moved into the engagement direction or the disengagement direction by actuating the fork 270.

[0049] The sleeve 150 is connected to the coupling ring 130. One end of the sleeve 150 can be inserted (e.g., fitted) into the leg part 132 of the coupling ring 130 and assembled (e.g., mounted) therein.

[0050] The sleeve 150 can push the coupling ring 130 in one direction towards the retaining / supporting ring 120 to allow the second claw tooth 131 of the coupling ring 130 to engage with the first claw tooth 121 of the retaining / supporting ring 120. Alternatively, the sleeve 150 can pull the coupling ring 130 in a direction opposite to that of the retaining / supporting ring 120 to allow the second claw tooth 131 of the coupling ring 130 to disengage from the first claw tooth 121 of the retaining / supporting ring 120.

[0051] Specifically, in the case of four-wheel drive, the clutch ring 130 is pressed towards the retaining / support ring 120 by actuating the sleeve 150, so that the second claw tooth part 131 engages with the first claw tooth part 121. In the case of two-wheel drive, the clutch ring 130 is pulled in the opposite direction to the retaining / support ring 120 by actuating the sleeve 150, so that the second claw tooth part 131, which engages with the first claw tooth part 121, can disengage from the first claw tooth part 121 or become disengaged from it.

[0052] The actuating device 200 can be modularized by means of a housing 210. The actuating device 200 comprises: the housing 210, a motor (e.g., electric motor, e.g., servo motor) 220 coupled to the housing 210, a ball screw shaft 230 configured to be rotated by operation of the motor 220, a transmission nut 250 configured to move linearly along the ball screw shaft 230 when the ball screw shaft 230 rotates, and the fork 270 integrated with the transmission nut 250 and configured to move together with the transmission nut 250.

[0053] The housing 210, which unlike a reduction gear (not shown) does not absorb (e.g. experience) a high external force, can be made of a lightweight material, such as aluminum or engineering plastic, thereby reducing the weight of the reduction gear (e.g., the housing 210).

[0054] The motor 220 can, for example, be a BLDC motor (e.g., a brushless DC motor). The ball screw shaft 230, the transmission nut 250, and the fork 270 are mounted in the housing 210. The ball screw shaft 230 is connected to the motor 220. The ball screw shaft 230 can be rotatably mounted in the housing 210 by means of a retaining / supporting element 240, such as a bearing.

[0055] A transmission power of the fork 270, which is insufficiently provided by means of the motor 220, can be amplified and then transmitted by means of the ball screw shaft 230, which enables precise control.

[0056] The transmission nut 250 is coupled to the ball screw shaft 230. When the ball screw shaft 230 rotates, the transmission nut 250 can move stably while being guided by a guide rail 260 mounted in the housing 210.

[0057] The guide rail 260 is penetratingly connected to the transmission nut 250, and two opposite ends of the guide rail 260 are / are held (e.g. supported) by the housing 210.

[0058] The fork 270 extends towards the sleeve 150 through an opening section 211 of the housing 210. The fork 270 is coupled to and surrounds the outer diameter section of the sleeve 150.

[0059] The opening section 211 of the housing 210 can be designed as a space that corresponds to a stroke of the fork 270 (e.g. adapted to it), so that the fork 270 can move smoothly (e.g. without obstruction / interference).

[0060] A sealing element 280, such as an O-ring, can be coupled to the housing 210. The sealing element 280 can be coupled to a coupling surface 212 of the housing 210, to which the motor 220 is coupled.

[0061] The sealing element 280 can prevent liquid or oil mist, which may be generated by a lubricating oil in the reduction gear (not shown), from entering the motor 220.

[0062] Next, an operation in the case of the two-wheel drive of the present invention will be described.

[0063] Fig. Figure 5 is a view showing a process in which the retaining ring / support ring and the coupling ring are engaged with each other according to the exemplary embodiment of the present invention.

[0064] As in Fig. 4 and Fig. Figure 5 shows that when the ball screw shaft 230 is rotated by the operation of the motor 220, the transmission nut 250 moves backward (e.g., backward). When the transmission nut 250 moves backward (e.g., backward), the fork 270 integrated with the transmission nut 250 moves the sleeve 150 backward (e.g., backward).

[0065] Since the sleeve 150 pulls the clutch ring 130 in the opposite direction to the retaining / support ring 120 while moving backwards (e.g., backwards), the second claw tooth part 131 can move away from the first claw tooth part 121 and become disengaged. Therefore, two-wheel drive (2WD) can be implemented.

[0066] In the disengaged state, the power from the input component (not shown), such as the electric motor or the internal combustion engine, is blocked. The power from the input component is not transmitted to the final gear 190.

[0067] Two opposing auxiliary drive gears (not shown) are idling (e.g., rotating without being driven), the torque of the two opposing auxiliary drive gears can be transmitted to the first lateral gear 141 and the second lateral gear 142, so that the first lateral gear 141 and the second lateral gear 142 can rotate (for example: If / Because two opposing auxiliary drive gears (not shown) are idling (e.g., rotating without being driven), the torque of the two opposing auxiliary drive gears can be transmitted to the first lateral gear 141 and the second lateral gear 142, so that the first lateral gear 141 and the second lateral gear 142 can rotate).

[0068] Because the first side gear 141 and the second side gear 142 are engaged with the pinion 143, the retaining ring / support ring 120 can rotate together with the first side gear 141 and the second side gear 142 when the first side gear 141 and the second side gear 142 rotate (e.g. when they are / are being rotated).

[0069] In this case, since the retaining / supporting ring 120 is / will be separated from the housing 110, only the retaining / supporting ring 120 rotates, but the housing 110 does not. Therefore, the two-wheel drive, in which only the main drive wheels propel the vehicle and the auxiliary drive wheels remain unpowered, can be / will be implemented.

[0070] Since the electric vehicle operates at a high speed, high differential noise can certainly occur. However, the present invention can solve the problem of high differential noise in the related technology because the retaining / support ring 120 rotates in the housing 110.

[0071] Next, an operation in the case of the four-wheel drive of the present invention will be described.

[0072] With reference to Fig. 4 and Fig. 5. When the ball screw shaft 230 is rotated by the operation of the motor 220, the transmission nut 250 moves forward. When the transmission nut 250 moves forward, the fork 270 integrated with the transmission nut 250 moves the sleeve 150 forward.

[0073] As the sleeve 150 pushes the clutch ring 130 towards the retaining / supporting ring 120 while moving forward, the second claw tooth part 131 of the clutch ring 130 engages with the first claw tooth part 121 of the retaining / supporting ring 120. Therefore, four-wheel drive (4WD) can be implemented.

[0074] In the case of four-wheel drive, the power of the input part (not shown), such as the electric motor or the internal combustion engine, can be transferred to the final gear 190.

[0075] The power from the input section can be transmitted to the housing 110 via the end gear 190. The retaining / supporting ring 120 can rotate because / when the housing 110 rotates. The housing 110 and the retaining / supporting ring 120 are coupled (e.g., to each other, e.g., against each other) and move together.

[0076] When the retaining ring / support ring 120 rotates, the force is transferred to both the first and second side gears 141 and 142, which are engaged with the pinion 143, so that the first and second side gears 141 and 142 can rotate.

[0077] When the first lateral gear 141 and the second lateral gear 142 rotate, power is transferred to the two opposing auxiliary drive gears connected to the first and second lateral gears 141 and 142 (e.g., in an associated manner), allowing the two opposing auxiliary drive gears to rotate. Therefore, four-wheel drive can be realized, as the power from the input is transferred to both the auxiliary drive gears and the main drive gears.
