Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of vehicle accessories, in particular to a clutch device and a stabilizer bar system. BACKGROUND

[0002] The stabilizer bar is part of the automobile suspension system, which can adjust the inclination angle of the vehicle when the vehicle turns, so as to avoid the risk of the vehicle tilting and even the risk of the wheels on one side being lifted when the inclination angle is too large.

[0003] At present, passive stabilizer bars are mostly used in vehicles. The passive stabilizer bar can only select a moderate performance to meet the anti-rollover of the vehicle in various situations, and cannot adjust the stiffness of the stabilizer bar according to the specific operation situation and demand of the vehicle.

[0004] Therefore, it is urgent to provide a clutch device and a stabilizer bar system to solve the problem of the existing technology to some extent. SUMMARY

[0005] The purpose of the present application is to provide a clutch device and a stabilizer bar system to solve the problem of the existing stabilizer bar that cannot adjust the stiffness according to the demand.

[0006] The clutch device provided by the present application comprises a positioning assembly, a stop member, a transmission shaft, an electromagnetic assembly and a sliding assembly. The stop member is connected with the positioning assembly, the center of the stop member is formed with a through hole part, the transmission shaft is rotatably connected with the stop member through the through hole part, and the stop member is formed with a containing part in communication with the through hole part. The electromagnetic assembly and the sliding assembly are both arranged in the containing part. The sliding assembly comprises an elastic member and a sliding block. The electromagnetic assembly is connected with one end of the sliding block away from the through hole part. The elastic member is located between the electromagnetic assembly and the stop member. The electromagnetic assembly is energized to drive the sliding block to move in the containing part, so that one end of the sliding block away from the elastic member enters or leaves the through hole part and abuts against or separates from the transmission shaft.

[0007] The electromagnetic assembly comprises a first electromagnetic member and a second electromagnetic member. The first electromagnetic member is arranged at one end of the containing part away from the through hole part. The second electromagnetic member is connected with one end of the sliding block away from the through hole part.

[0008] Specifically, when the elastic member is a tension spring, the first electromagnetic member and the second electromagnetic member generate repulsive force after being energized.

[0009] Specifically, when the elastic member is a compression spring, the first electromagnetic member and the second electromagnetic member generate attractive force after being energized.

[0010] Further, the positioning assembly comprises a shell and an anti-skid member connected with the shell, the anti-skid member is annular, and a first matching part is formed on the inner ring of the anti-skid member, a second matching part is formed on the outer ring of the stop member, and the second matching part is engaged with the first matching part to make the stop member stationary relative to the anti-skid member in the circumferential direction.

[0011] Further, a first engaging part is formed on the end face of the end of the sliding block abutting against the transmission shaft, and a second engaging part is formed on the outer wall of the transmission shaft along the circumferential direction of the transmission shaft, and the first engaging part is engaged with the second engaging part.

[0012] The sliding block comprises a sliding section and an abutting section, the abutting section is located at the end of the sliding section away from the elastic member, and the abutting section is located in the through hole, and the cross section of the abutting section is arc-shaped.

[0013] Specifically, the accommodating parts are multiple, and the multiple accommodating parts are arranged at intervals along the circumferential direction of the transmission shaft.

[0014] Further, the sliding section is in a cylindrical column structure, and the cross section of the accommodating part is circular with a diameter not less than the diameter of the sliding section.

[0015] Compared with the prior art, the clutch device provided by the application has the following advantages:

[0016] The clutch device comprises a positioning assembly, a stop member, a transmission shaft, an electromagnetic assembly and a sliding assembly; the stop member is connected with the positioning assembly, the center of the stop member is formed with a through hole, the transmission shaft is rotationally connected with the stop member through the through hole, and the stop member is formed with an accommodating part in communication with the through hole; the electromagnetic assembly and the sliding assembly are arranged in the accommodating part, the sliding assembly comprises an elastic member and a sliding block, the electromagnetic assembly is connected with one end of the sliding block away from the through hole, and the elastic member is located between the electromagnetic assembly and the stop member; energization of the electromagnetic assembly can drive the sliding block to move in the accommodating part, so that the one end of the sliding block away from the elastic member enters or leaves the through hole to abut against or separate from the transmission shaft.

[0017] From the analysis, it can be seen that, by connecting the stop member with the positioning assembly, since the positioning assembly is a fixed structure, the stop member is prevented from moving. The through hole formed in the center of the stop member can make the transmission shaft of the stabilizer bar system pass through the stop member. Moreover, in the application, the stop member is formed with an accommodating part in communication with the through hole, and the electromagnetic assembly and the sliding assembly are arranged in the accommodating part, the sliding assembly comprises a sliding block and an elastic member, and the electromagnetic assembly is connected with one end of the sliding block, so that when the electromagnetic assembly is energized, the sliding block can be driven to move in the accommodating part, so that the one end of the sliding block away from the elastic member can enter or leave the through hole.

[0018] When the slider enters the through hole away from the end of the elastic member, the slider can abut against the transmission shaft passing through the through hole, so that the clutch device is in a closed state, and the reducer and the stabilizer bar are in a closed state, in which the stabilizer bar has adjustable torsional stiffness, so that the stiffness of the stabilizer bar can be adjusted according to requirements. When the slider enters the accommodating portion away from the end of the elastic member, the slider is separated from the transmission shaft, and the clutch device is in an open state, in which the stabilizer bar has small torsional stiffness, so that the vehicle can be more comfortable when driving in a straight line or smoothly.

[0019] In addition, the application also provides a stabilizer bar system, comprising a stabilizer bar, a power mechanism and the clutch device described above; the power mechanism comprises a motor and a reducer, the motor is connected with the reducer, and the clutch device is located between the output end of the reducer and the stabilizer bar.

[0020] The clutch device arranged between the output end of the reducer and the stabilizer bar can realize the opening and closing of the power mechanism and the stabilizer bar, so as to adjust the stiffness of the stabilizer bar, and then the overall vehicle can adjust the roll angle according to specific requirements, and the comfort of the vehicle is improved.

[0036] like Figures 1-4 As shown, the present invention provides a clutch device, including a positioning component, a stop member 3, a transmission shaft 4, an electromagnetic component, and a sliding component. The stop member 3 is connected to the positioning component, and a through hole is formed in the center of the stop member 3. The transmission shaft 4 passes through the through hole and is rotatably connected to the stop member 3. A receiving portion 301 communicating with the through hole is formed inside the stop member 3. The electromagnetic component and the sliding component are both disposed in the receiving portion 301. The sliding component includes an elastic element 6 and a slider 5. The electromagnetic component is connected to the end of the slider 5 away from the through hole. The elastic element 6 is located between the electromagnetic component and the stop member 3. When the electromagnetic component is energized, the slider 5 can be driven to move within the receiving portion 301, so that the end of the slider 5 away from the elastic element 6 enters or leaves the through hole and abuts or separates from the transmission shaft 4.

[0037] Compared with the prior art, the clutch device provided by the application has the following advantages:

[0038] The clutch device provided by the application is characterized in that the stop member 3 is connected with the positioning assembly, the positioning assembly is a fixed structure, and thus movement of the stop member 3 is avoided. The through hole formed in the center of the stop member 3 can allow the transmission shaft 4 of the stabilizer bar system to pass through the stop member 3. In addition, the stop member 3 is internally formed with a receiving portion 301 that is in communication with the through hole, and the electromagnetic assembly and the sliding assembly are arranged in the receiving portion 301. The sliding assembly comprises a sliding block 5 and an elastic member 6, and the electromagnetic assembly is connected with one end of the sliding block 5. Thus, when the electromagnetic assembly is energized, the sliding block 5 can be driven to move in the receiving portion 301, so that the sliding block 5 moves away from the one end of the elastic member 6 to enter or leave the through hole.

[0039] When the one end of the sliding block 5 moves away from the elastic member 6 to enter the through hole, the sliding block 5 can abut against the transmission shaft 4 passing through the through hole, so that the clutch device is in a closed state, and thus the speed reducer and the stabilizer bar are in a closed state. In this state, the stabilizer bar has adjustable torsional stiffness, and thus the stiffness of the stabilizer bar can be adjusted according to requirements.

[0040] It can be understood that the electromagnetic assembly comprises a first electromagnetic member and a second electromagnetic member in the application. The first electromagnetic member is arranged at the one end of the receiving portion 301 that is away from the through hole, and the second electromagnetic member is connected with the one end of the sliding block 5 that is away from the through hole.

[0041] In the application, the first electromagnetic member is located at the bottom of the receiving portion 301, the second electromagnetic member is connected with the sliding block 5, and the elastic member 6 is located between the first electromagnetic member and the second electromagnetic member.

[0042] Thus, when the elastic member 6 is a tension spring, the elastic member 6 always exerts a pulling force on the sliding block 5 in a natural state, so that the sliding block 5 can be kept in the receiving portion 301 and does not abut against the transmission shaft 4, and the transmission shaft 4 can rotate freely, and the clutch device is in an open state.

[0043] In this embodiment, when it is required to move the sliding block 5 in a direction close to the transmission shaft 4, the sliding block 5 needs to overcome the pulling force of the elastic member 6. Thus, the first electromagnetic member and the second electromagnetic member need to be energized to generate repulsive forces, so that the sliding block 5 is driven to move in the direction close to the transmission shaft 4 under the driving of the repulsive forces until the sliding block 5 abuts against the transmission shaft 4, and the clutch device is closed.

[0044] It is understood that, in this embodiment, the first and second electromagnetic components need to be energized at all times to achieve the closing of the clutch device.

[0045] When the elastic element 6 is a pressure spring, the elastic element 6 always applies a pushing force to the slider 5 in its natural state, so that the end of the slider 5 away from the elastic element 6 always protrudes from the receiving part 301 and abuts against the transmission shaft 4, so that friction is generated between the slider 5 and the transmission shaft 4 to lock the transmission shaft 4. At this time, the clutch device is in the closed state.

[0046] In this embodiment, when it is necessary to separate the slider 5 from the drive shaft 4, the slider 5 needs to be able to overcome the thrust of the elastic element 6. Therefore, the first and second electromagnetic elements need to be energized to generate an attractive force, so that the slider 5 can be moved away from the drive shaft 4 under the drive of the attractive force until it comes into contact with the drive shaft 4, thereby disengaging the clutch device.

[0047] It is understood that, in this embodiment, disengaging the clutch device requires constant energization of the first and second electromagnetic components.

[0048] It should be noted that the first and second electromagnetic components mentioned above in this application are both electromagnets.

[0049] Optionally, such as Figure 2 Combination Figure 4 As shown, the positioning component in this application includes a housing 1 and an anti-slip member 2. The anti-slip member 2 is connected to the housing 1. The anti-slip member 2 is annular, and the inner ring of the anti-slip member 2 forms a first mating part 201. The outer ring of the stop member 3 forms a second mating part 302. The second mating part 302 engages with the first mating part 201 so that the stop member 3 is stationary relative to the anti-slip member 2 in the circumferential direction.

[0050] In this application, the anti-slip component 2 and the housing 1 can be fixedly connected by welding or other means. The housing 1 can be fixedly connected to the vehicle subframe. Therefore, the first mating part 201 formed by the inner ring of the anti-slip frame and the second mating part 302 formed by the outer ring of the stop component 3 are used to make the first mating part 201 and the second mating part 302 cooperate to achieve the fixation of the stop component 3 and the anti-slip component 2 in the circumferential direction.

[0051] It is understood that in this application, the first mating part 201 formed on the inner ring of the anti-slip component 2 is an internal spline, and the second mating part 302 formed on the outer ring of the stop component 3 is an external spline. The circumferential positioning between the stop component 3 and the anti-slip component 2 is achieved through the mating of the internal spline and the external spline.

[0052] It should be noted that the stop member 3 can move axially relative to the anti-skid member 2, and the planetary gear in the speed reducer can move axially, so that the stop member 3 moves axially, thereby avoiding the interference between the stop member 3 and the planetary gear to a certain extent. In addition, the contact position between the stop member 3 and the planetary gear can be changed each time the speed reducer is closed, thereby reducing the wear.

[0053] To improve the stability of the clutch device in the closed state, preferably, a first engaging portion is formed on the end face of the end of the sliding block 5 abutting against the transmission shaft 4, and a second engaging portion is formed on the outer wall surface of the transmission shaft 4 and along the circumference of the transmission shaft 4. The first engaging portion and the second engaging portion are engaged with each other.

[0054] Through the first engaging portion and the second engaging portion, when the end face of the sliding block 5 abuts against the transmission shaft 4, the first engaging portion and the second engaging portion can be stably engaged, thereby locking the transmission shaft 4. Compared with the locking of the transmission shaft 4 by the friction force, the locking is more reliable.

[0055] Further preferably, as shown in Figure 4 The sliding block 5 in the application includes a sliding section 501 and an abutting section 502. The abutting section 502 is located at the end of the sliding section 501 away from the elastic member 6, and is located in the perforated portion. The cross section of the abutting section 502 is arc-shaped. Through the arc-shaped abutting section 502, the contact area between the sliding block 5 and the transmission shaft 4 can be increased, thereby increasing the friction force and improving the locking effect of the transmission shaft 4.

[0056] Optionally, as shown in Figure 2 In combination with Figure 4 The accommodating portion 301 in the application is a plurality of accommodating portions 301, and the plurality of accommodating portions 301 are arranged at intervals along the circumference of the transmission shaft 4.

[0057] In the first embodiment, the number of the accommodating portions 301 is eight, and the accommodating portions 301 are arranged at equal intervals along the circumference of the transmission shaft 4. Correspondingly, the number of the sliding blocks 5, the elastic members 6, the first electromagnetic members and the second electromagnetic members is eight, thereby increasing the stability of the locking of the transmission member.

[0058] In the second embodiment, the number of the accommodating portions 301 is two, and the accommodating portions 301 are arranged oppositely. Correspondingly, the number of the sliding blocks 5, the elastic members 6, the first electromagnetic members and the second electromagnetic members is two. In this embodiment, the sliding block 5 with the arc-shaped abutting section 502 is used, and the diameter of the sliding section 501 is greater than that of the sliding block 5 in another embodiment, thereby increasing the overall strength of the sliding block 5 in this form.

[0059] It can be understood that the two sliding sections 501 are in cylindrical column structures, and the cross section of the accommodating portion 301 is circular, and the diameter is not less than the diameter of the sliding section 501, so that the slider 5 can move smoothly in the accommodating portion 301.

[0060] In addition, the application further provides a stabilizer system, comprising a stabilizer, a power mechanism and the clutch device; the power mechanism comprises a motor and a speed reducer, the motor is connected with the speed reducer, and the clutch device is located between the output end of the speed reducer and the stabilizer.

[0061] The clutch device arranged between the output end of the speed reducer and the stabilizer can realize the disconnection and closure between the power mechanism and the stabilizer, so as to realize the adjustment of the rigidity of the stabilizer, and then the overall vehicle can adjust the roll angle according to the specific needs, and the vehicle comfort is improved.

[0062] The above only describes the preferred embodiments of the application and is not used to limit the application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the application shall be included in the protection scope of the application.
