Description

Technical Field

[0001] The invention relates to the technical field of clutches, and in particular to a high-speed self-disengaging switching clutch. Background Art

[0002] Clutches are widely used in various mechanical transmission systems. Gear-type controllable clutches have large torque transmission, high power density, compact structure, and good dynamic stability. They are widely used in situations where high speed, high power, and high dynamic stability are required. Gear clutches have many application scenarios, and the main working method is to achieve the engagement and disengagement of the clutch through the axial relative relationship of the sleeve teeth. When the axial positions of the drive sleeve teeth coincide, the clutch engages; when the axial positions of the drive sleeve teeth are misaligned, the clutch disengages. Due to the driving principle, the disengagement action of the existing gear clutch generally requires hydraulic, pneumatic or electromagnetic drive, which increases the complexity of the clutch auxiliary system and limits its application in special equipment fields such as water-air cross-media environment observation and fire rescue. These special equipment are not frequently used, and the clutch only needs to complete one disengagement action in a single mission profile under special conditions. The direct use of traditional clutch systems is too complicated and will reduce the effective load of the equipment in performing tasks.

[0003] Therefore, the existing clutch has the problem of being unable to stably disengage under high speed conditions without an external driving source. Summary of the invention

The inner walls of the two blind holes on the circumferential outer surface of the regulating component 20 are both processed with threads, and a limit screw plug 290 is provided at the inner top of each blind hole on the circumferential outer surface of the regulating component 20. A working oil hole 202 is processed at the inner top of the annular pre-oil chamber 203 of the regulating component 20 along the axis, and the annular pre-oil chamber 203 is connected to the inside of the two blind holes on the circumferential outer surface of the regulating component 20 through the working oil hole 202;

[0008] Furthermore, a boss is processed at the center of the other end surface of the regulating component 20;

[0009] Furthermore, the end surface of the boss on the regulating component 20 contacts the end surface of the sliding component 30, and the end surface of the sliding component 30 is processed with a ring platform along the circumferential edge, and the inner surface of the ring platform and the outer surface of the boss on the regulating component 20 form a working oil chamber 204;

[0010] Furthermore, the transmission shaft 10, the regulating assembly 20, the sliding assembly 30 and the output assembly 40 are coaxially arranged;

In the static state, the plug 210 is removed and the annular pre-oil filling chamber 203 is filled with working oil through the oil filling hole 201; in the initial state, the push rod spring 220 is in a pre-compression state, providing an appropriate axial force for the push rod 230, and the working surface of the push rod 230 is pressed against the outer surface of the No. 1 piston rod 240. The No. 1 piston rod 240 and the No. 1 spring 250 are installed in a radial hole perpendicular to the axis of the clutch. The No. 1 spring 250 is in a pre-compression state to provide a force for the No. 1 piston rod 240 so that the No. 1 piston rod 240 blocks the working oil. Hole 202, the axial force provided by the push rod spring 220 to the push rod 230 should not be too large to avoid affecting the flexibility of the No. 1 piston rod 240 moving along the radial hole. The No. 2 spring 260 and the No. 2 piston rod 270 are installed in the radial hole perpendicular to the axis of the clutch. The No. 2 spring 260 is in a pre-compression state to provide a force for the No. 2 piston rod 270 so that the No. 2 piston rod 270 cannot block the working oil hole 202. At this time, the working oil hole 202 and the working oil chamber 204 are in a disconnected state; the sliding component 30 is provided with an internal meshing tooth 301, and the output component 40 is provided with an external meshing tooth 401. In the initial state, the internal meshing tooth 301 and the external meshing tooth 401 are in a meshing state;

[0014] When the clutch speed exceeds Ws1, the centrifugal force on the No. 2 piston rod 270 is greater than the preload provided by the No. 2 spring 260, and the No. 2 piston rod 270 moves along the radial hole on the regulating assembly 20, so that the No. 2 piston rod 270 contacts the limit screw plug 290. The No. 2 piston rod 270 is a stepped cylindrical surface. After the No. 2 piston rod 270 moves to this position, the working oil hole 202 can be blocked. At this time, the No. 1 spring 250 is still in a compressed state, and the centrifugal force on the No. 1 piston rod 240 is not enough to overcome the force of the No. 1 spring 250, and the No. 1 piston rod 240 is still in a state of blocking the working oil hole 202.

[0015] When the clutch speed exceeds Ws2, the centrifugal force on the No. 2 piston rod 270 is still greater than the preload provided by the No. 2 spring 260, and the No. 2 piston rod 270 can still block the working oil hole 202; at this time, the centrifugal force on the No. 1 piston rod 240 is greater than the preload provided by the No. 1 spring 250, and the No. 1 piston rod 240 moves along the radial hole on the regulating component 20, so that the No. 1 piston rod 240 contacts another limit screw plug 290, and the No. 1 piston rod 240 releases the blocking state of the working oil hole 202. The No. 1 piston rod 240 is a stepped cylindrical surface. After the No. 1 piston rod 240 moves to this position, the push rod 230 moves axially along the axial hole under the action of the push rod spring 220, and the head of the push rod 230 is inserted into the annular surface of the No. 1 piston rod 240. Under the limiting action of the head of the push rod 230, the position of the No. 1 piston rod 240 is maintained in the state of releasing the blocking state of the working oil hole 202;

[0016] When the clutch speed drops to Wj1, the centrifugal force on the No. 2 piston rod 270 is less than the preload provided by the No. 2 spring 260, and the No. 2 piston rod 270 moves along the radial hole on the regulating assembly 20 and returns to the initial installation position. The No. 2 piston rod 270 is a stepped cylindrical surface. After the No. 2 piston rod 270 moves to this position, the blockage of the working oil hole 202 can be released. At this time, the position of the No. 1 piston rod 240 is still maintained in the state of releasing the blockage of the working oil hole 202, and the annular pre-filled oil chamber 203 and the working oil chamber 204 are connected through the working oil hole 20 2 keeps connected, and the pre-filled working oil in the annular pre-filled oil chamber 203 flows into the working oil chamber 204 through the working oil hole 202. Since it is still in a high-speed running state at this time, the working oil flowing into the working oil chamber 204 generates an axial force on the sliding assembly 30 under the action of centrifugal force. As the working oil flowing into the working oil chamber 204 continues to increase, the axial force on the sliding assembly 30 becomes larger and larger, until the internal meshing teeth 301 on the sliding assembly 30 and the external meshing teeth 401 on the output assembly 40 are completely axially misaligned, and the clutch is disengaged at this time.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] The present invention overcomes the shortcomings of the prior art. The clutch of this structure does not require an external oil source, air source or other driving source. By pre-injecting working oil in the clutch and arranging multiple groups of piston rods on the regulating component, the centrifugal effect is utilized to realize automatic disengagement of the clutch under specific application conditions and specific speed conditions. The structure of the clutch is more compact, and no additional control unit is required. The clutch can adaptively disengage as the working speed changes. The clutch is particularly suitable for use in special operation equipment such as environmental surveys and fire rescue. BRIEF DESCRIPTION OF THE DRAWINGS

The No. 1 piston rod 240 and the No. 1 spring 250 are installed in a radial hole perpendicular to the axis of the clutch. The No. 1 spring 250 is in a pre-compression state to provide a force for the No. 1 piston rod 240 so that the No. 1 piston rod 240 blocks the working oil hole 2 02, the axial force provided by the push rod spring 220 to the push rod 230 should not be too large to avoid affecting the flexibility of the No. 1 piston rod 240 moving along the radial hole.
