Compared with the prior art, the invention has the following beneficial technical effects due to the adoption of the technical scheme:

1. in the invention, the gas in the pressure building cavity of the clutch is exhausted by configuring an exhaust self-checking device, and on the premise of good air tightness, when the pressure building cavity is compressed to the minimum volume, the atmospheric negative pressure borne by a piston piece in the pressure building cavity is balanced with the thrust of the force bearing guide rod borne by the piston piece and the elastic force of a return spring in the pressure building cavity, so that the pressure building cavity keeps the minimum volume within a preset time interval, namely, the force bearing guide rod keeps the position within the preset time interval without return movement; then, the balance of the piston piece can be broken through continuously or discontinuously opening the exhaust self-checking device, so that the piston piece can slowly push the force bearing guide rod to move towards the direction of the oscillating bar until the force bearing guide rod is in butt joint with the guide rod, and the butt joint process between the force bearing guide rod and the oscillating bar is more convenient and controllable;

2. based on the installation process, the working engineering of the exhaust self-checking device can also be applied to the exhaust detection process of the clutch electromechanical structure; specifically, compared with the detection mode in the prior art that auxiliary equipment conforming to an air source, a pressure gauge or an air pressure sensor, test software and the like is needed, the detection of the electromechanical actuating device of the automatic transmission can be completed without the aid of the auxiliary equipment by arranging the exhaust self-checking device on the electromechanical actuating device; meanwhile, a channel switch between a pressure building cavity of the electromechanical execution structure and the outside atmosphere is constructed by utilizing the exhaust self-checking device, and a channel between the pressure building cavity and the outside atmosphere is in a closed state under a normal state;

3. the exhaust self-checking device provided by the invention is characterized in that a normally closed channel from a pressure building cavity to the outside atmosphere is constructed through a fixed piece and a movable piece, the channel is defined as an exhaust channel, namely, the exhaust channel is in a closed state in a non-use state (or a non-detection state), when the exhaust self-checking device needs to be used, the movable piece is moved and is released from sealing contact with the fixed piece, so that the exhaust channel in the exhaust device is opened, the pressure building cavity and the outside form a channel, and residual gas in the pressure building cavity is exhausted through the exhaust channel.

4. Further, when the characteristics of the exhaust self-checking device are applied to the air tightness detection process of the electromechanical execution structure, firstly, the exhaust self-checking device is operated to open the exhaust channel, then the force-bearing guide rod of the electromechanical device is approximately vertically abutted against the rigid support, the volume of the pressure building cavity is enabled to be the minimum value by overcoming the return spring in the pressure building cavity, the gas in the pressure building cavity is exhausted from the exhaust channel, then, the exhaust self-checking device is operated to close the exhaust channel, at the moment, the negative pressure of the gas borne by the piston piece in the pressure building cavity, the elastic force of the return spring of the pressure building cavity to the piston piece and the thrust of the force-bearing guide rod to the piston piece are in a balanced state within preset time, and at the moment, if the sealing performance of each sealing piece in the pressure building cavity is good, the force-bearing guide rod should be kept in a stable state within the preset time and does not return; on the contrary, if the exhaust self-checking device is operated to enable the bearing guide rod to return after the exhaust channel is closed, the problem of air tightness of the sealing element in the pressure building cavity is indicated;

6. in the process, the annular inclined plane reserves a space for deformation of the rubber sealing sleeve, so that the air tightness between the outer valve body and the retainer cannot lose due to repeated extrusion caused by movement of a moving part, and the air tightness between the outer valve body and the retainer cannot be lost; correspondingly, the inner wall of the retainer also forms a convergent annular inclined plane, thereby playing a role in ensuring the sealing effect of the device;

7. in order to prevent external dust and silt from entering the pressure building cavity through the exhaust self-checking device, a dustproof cover covering the door control device and the outer valve body is arranged at the top of the door control device, and a gap is reserved between the dustproof cover and the fixing piece (the outer valve body), so that when pollutants are prevented from entering the cavity, when high-pressure gas in the pressure building cavity is exhausted, the exhaust pressure can be obviously reduced.

Detailed Description

Embodiments of an AMT clutch electro-mechanical docking method and a clutch electro-mechanical device with docking according to the present invention will be described below with reference to the accompanying drawings. Those skilled in the art will recognize that the described embodiments may be modified in various different ways, without departing from the spirit and scope of the present invention. Accordingly, the drawings and description are to be regarded as illustrative in nature, and not as restrictive on the scope of the claims. Furthermore, in the present description, the drawings are not drawn to scale and like reference numerals designate like parts.

It should be noted that, in the embodiments of the present invention, the expressions "first" and "second" are used to distinguish two entities with the same name but different names or different parameters, and it should be understood that "first" and "second" are merely for convenience of description and should not be construed as limitations of the embodiments of the present invention, and no description thereof is provided in the following embodiments.

The AMT clutch electromechanical docking method in the preferred embodiment of the invention is realized based on an exhaust self-checking device arranged on the clutch electromechanical device. The exhaust self-checking device is a controllable channel from a pressure building cavity of the clutch electromechanical device to the outside atmosphere, so that the exhaust of gas in the pressure building cavity or the exhaust of gas into the pressure building cavity is realized by controlling the exhaust self-checking device.

The specific mode is that a drainage channel is configured, one end of the drainage channel is communicated with the atmosphere, and the other end of the drainage channel is communicated with a pipeline between a valve port of a clutch electromechanical device control valve body and a pressure building cavity; then, an exhaust self-checking device is arranged at the opening position of the drainage channel communicated with the atmosphere, the inner cavity of the exhaust self-checking device is in butt joint with the drainage channel, and an exhaust channel which is closed under the normal state is formed in the exhaust device; then, keeping the exhaust self-checking device in an opening state, simultaneously compressing the pressure building cavity to reach the minimum volume of the pressure building cavity, and then closing the exhaust self-checking device; and finally, continuously or intermittently operating the exhaust self-checking device to continuously or intermittently open the exhaust channel inside the exhaust self-checking device so as to continuously or intermittently move the force bearing guide rod towards the direction of the oscillating rod until the force bearing guide rod is butted with the oscillating rod.

Referring to fig. 1 and 2, fig. 1 is a sectional view showing a sectional structure of an electromechanical device with a self-checking clutch in a preferred embodiment of the present invention; fig. 2 is a state diagram showing a state in which the electromechanical device with the docking clutch shown in fig. 1 is assembled with the swing lever. As shown in fig. 1, the clutch electromechanical device 100 includes a pressure building chamber 101 in the cylinder, a piston member 103 driven by a force bearing guide rod 102 is arranged in the pressure building chamber 101, and a return spring 104 abutting against the piston member 103, and referring to fig. 2 again, in an assembled state, the force bearing guide rod 102 of the clutch electromechanical device 100 is coupled with a swing rod ball socket on a swing rod 105 to realize continuous contact linkage butt joint. The oscillating bar 105 is acted by a preset return force, so that one end of the oscillating bar 105 connected with the force bearing guide rod 102 always keeps the trend of moving towards one side of the clutch electromechanical device 100, and pushes the force bearing guide rod 102 to drive the piston piece 103 to compress the return spring 104 to move until the elastic force generated by the deformation of the return spring 104 is balanced with the thrust of the oscillating bar 105 to the force bearing guide rod 102 and then stands. Referring back to fig. 1, the clutch electromechanical device further includes two electromagnetic devices 106, wherein a valve port of the electromagnetic device 106 corresponding to the air inlet end is communicated with the pressure buildup chamber 101 through a pipeline. In the preferred embodiment of the present invention, a channel is formed on the cylinder of the clutch electromechanical device, one end of the channel is communicated with the outside atmosphere, and the other end of the channel is communicated with a pipeline of the valve port of the electromagnetic device 106 and the pressure-building cavity 101, and the channel is defined as a drainage channel 107 in the present invention. When solenoid 106 is closed, as shown in fig. 1, pressure-building chamber 101 may be vented to the outside through a flow-directing passage 107, or alternatively, pressure-building chamber 101 may be inflated through flow-directing passage 107. The self-test exhaust device 200 is interfaced with the flow channel 107. With reference to fig. 1, the exhaust self-checking device 200 is fixedly connected to the cylinder at the port of the flow-guiding channel 107. the idea of the present invention is to control the connection and disconnection between the flow-guiding channel 107 and the outside atmosphere by using the exhaust self-checking device 200 as a switch of the flow-guiding channel 107.

Next, the exhaust self-inspection apparatus 200 is described in detail. The exhaust self-checking device in this embodiment of the present invention is substantially configured with a fixed member and a movable member, wherein the fixed member is used for fixedly connecting with a cylinder body of a passage port of the drainage channel 107, and the movable member is disposed in the fixed member, and is in a normal state, i.e., in a non-open state, and is in pressing contact with the fixed member to form a seal, and at this time, the drainage channel 107 is isolated from the outside. In the open state, by releasing the pressing contact between the movable member and the fixed member, the seal between the movable member and the fixed member is lost, and the drainage passage 107 is communicated with the outside.

Fig. 3 is a partially enlarged sectional view showing a partially enlarged sectional structure of a portion a in fig. 2. As shown in fig. 3, the exhaust self-checking device according to a preferred embodiment of the present invention includes an outer valve body 201, a holder 202 with a vulcanizing valve and disposed in the outer valve body 201, and a door control device 203 disposed in the holder 202 and movable in the holder 202. The outer valve body 201 is fixed to the cylinder body at the opening of the flow guide channel 107 by screw threads, the outer valve body 201 is a hollow member, and the cavity formed by the hollow portion in the outer valve body 201 is defined as an exhaust channel 204, as shown in fig. 3, after the exhaust self-checking device 200 is fixed, the exhaust channel 204 is butted with the flow guide channel 107. A thread part 205 is formed on the inner side wall surface of the outer valve body 201, and a thread (not shown) corresponding to the thread part 205 of the outer valve body 201 is formed on the outer part of the retainer 202, so that the retainer can extend into the opening part of the outer valve body 201 and feed to the limit along the thread part, and the fixation with the outer valve body 201 is completed. It is easy to see that, in the preferred embodiment, the whole body formed by the outer valve body 201 and the retainer 202 is regarded as a fixing member, and the split design of the fixing member is more beneficial to prolonging the service life of the whole body, however, such a design inevitably requires consideration of the sealing effect between the two components, and with continued reference to fig. 3, in order to solve the sealing problem between the two components, the inner side wall surface of the outer valve body 201 forms an annular inclined surface converging toward the passage opening of the diversion passage 107, which is defined as a first annular inclined surface 206, after the outer valve body 201 is fixedly connected with the retainer 202, a gap is formed between the inner side surface of the outer valve body 201 and the outer profile surface of the retainer 202, in the preferred embodiment, the gap is filled and sealed by a gland 207 of vulcanized hard rubber material on the holder 202, therefore, when the sealing between the outer valve body 201 and the holding frame 202 is realized, the influence on the sealing effect between the outer valve body 201 and the holding frame 202 caused by the motion process of the control gate device 203 is avoided. In addition, it is worth mentioning that another conceivable way to solve the above-mentioned sealing problem between the two is to integrally form the outer valve body 201 and the retainer 202 into a fixing member, however, although the sealing problem between the two can be ignored, it is not favorable to prolong the service life of the whole structure, and the difficulty of structure modeling and assembly is increased.

And the gating device 203. Fig. 4 is a cross-sectional view showing a cross-sectional structure of the assembly of the door control device and the holder shown in fig. 3. In the preferred embodiment, the door control 203 is connected as a movable member to the holder 202. Specifically, with continued reference to fig. 3 and with reference to fig. 4, the door control device 203 is shown in cross-section as an "i" shaped elongated member, including two flanges at each end thereof, respectively defined as a first flange 2031 distal from the drainage channel 107 and a second flange 2032 proximal to the drainage channel 107. An elastic component 208 is fixedly connected between the first flange 2031 and the retainer 202, a sealing seat 209 is fixedly connected on the second flange 2032, an annular inclined surface which is consistent with the outer wall surface of the retainer 202 and is converged towards the direction of the channel opening of the drainage channel 107 is also formed on the inner wall surface of the retainer 202, the annular inclined surface is defined as a second annular inclined surface 210, and the inner tangent surface of the second annular inclined surface 210 is contacted with the sealing seat 209 on the second flange 2032 to form sealing. As previously discussed, the present general inventive concept requires that the movable member normally press against the fixed member to form a seal, and in the preferred embodiment, the door control device 203 normally tends to remain moving toward the first flange 2031 and is retained by the second annular inclined surface 210 of the retainer 202. In order to achieve the technical effect, in the preferred embodiment of the present invention, one end of the elastic component 208 is fixedly connected with the bottom surface of the first flange 2031, and the other end thereof is fixedly connected with the top surface of the retainer 202, on the basis of which, a predetermined amount of compression deformation is given to the elastic component 208, and the retainer 202 and the outer valve body 201 are screwed in for limiting, so that the elastic component 208 overcomes the elastic force generated by the compression elastic deformation thereof and can perform return movement towards the direction of the first flange 2031, and therefore, the door control device 203 always keeps the movement trend towards the direction of the first flange 2031 in a normal state, and is limited and forms sealing due to the contact and extrusion of the sealing seat 209 and the second annular inclined surface 210 on the inner wall of the retainer 202. In this way, the exhaust passage 204 in the self-inspection device 200 is closed in a normal state, that is, the drainage passage 107 is isolated from the outside in a normal state.

Referring back to fig. 3, it should be understood that the state shown in fig. 3, that is, the exhaust self-testing device 200 is in a normally closed state. Referring to the usage status of the self-checking device 200, the exhaust channel 204 is open, so that the drainage channel 107 is connected to the outside. Fig. 5 is a state diagram showing a state in which the exhaust passage in the exhaust self-checking apparatus shown in fig. 3 is opened. Referring to fig. 5, in the usage state, a force is applied to the first flange 2031 in a direction toward the second flange 2032, so as to further compress the elastic component 208, and the deformation generated thereby is larger than the preset compression deformation amount, and then the door control device 203 moves in the direction toward the second flange 2032, so that the normal movement tendency of the door control device 203 is overcome, that is, the pressing contact state and the sealing state of the sealing seat 209 thereon and the second annular inclined surface 210 are released, so that the exhaust passage 204 in the exhaust self-testing device 200 is opened, and the exhaust passage 204 serves as an intermediate passage to communicate the drainage passage 107 with the external atmosphere. In this state, referring to fig. 1 and 5, it can be seen that the pressure build chamber 101 is communicated with the external atmosphere, if there is gas in the pressure build chamber 101, the gas is discharged through the drainage channel 107 and the exhaust channel 204, and if the pressure build chamber is compressed to the minimum volume and negative pressure is formed in the pressure build chamber, the external gas slowly passes through the exhaust channel 204 and the drainage channel 107 and enters the pressure build chamber 101 through the continuous or intermittent opening exhaust self-checking device.

In the actual operation process, since the direction of the force applied to the door control device 203 by the operator is difficult to keep coincident with the axial direction of the door control device 203, the movement direction of the door control device 203 may be deviated after the force is applied, which may not only cause the release of the sealing state but also affect the service life of the door control device 203. In view of the above, in another preferred embodiment of the present invention, there is provided a structure of a door control device with a lead, fig. 6 is a cross-sectional view showing a cross-sectional structure of an exhaust gas self-checking device having a door control device shaped like a king character in another preferred embodiment of the present invention; fig. 7 is a state diagram showing a state in which the exhaust passage in the exhaust self-checking apparatus shown in fig. 6 is opened. Referring first to fig. 6, in the preferred embodiment, the door control device 203 is a long straight member with a "king" cross-section in cross-section, and a third flange 2033 is added between the first flange 2031 and the second flange 2032, so that the third flange 2033 is vertically between the first flange 2031 and the second flange 2032, and in the preferred embodiment, the seal housing 209 is located between the third flange 2033 and the second flange 2032 and is fixed with the second flange 2032. Referring to fig. 6 again, during the movement of the door control device 203 in this embodiment, the third flange 2033 can lead the vertical movement of the door control device 203 in the holding frame 202, so that it is difficult to deviate from the predetermined movement track. Thereby ensuring the effect of relieving the sealing state and also ensuring the service life of the door control device 203.

In addition, in order to prevent external dust and silt from entering the pressure building cavity 101 through the exhaust self-checking device 200, the dust cover 211 covering the door control device 203 and the outer valve body 201 is arranged at the top of the door control device 203, and a gap is reserved between the dust cover 211 and the fixing piece (the outer valve body), so that when pollutants are prevented from entering the cavity, and high-pressure gas in the pressure building cavity is exhausted, the exhaust pressure can be obviously reduced. In another embodiment of the present invention, the inner surface of the dust cover 211 may be fixed to the first flange 2031 of the door control device 203, so that the operation of the first flange 2031 of the door control device 203 may be switched to the operation of the dust cover 211.

In combination with the structure and the working process of the exhaust self-checking device 200, it should be understood that, in the prior art, after the oscillating bar of the clutch needs to overcome the elastic force of the corresponding elastic return device and is adjusted to a preset angle, the force-bearing guide rod and the oscillating bar are controlled to be in butt joint by a special auxiliary tool. In the invention, the exhaust self-checking device is configured to exhaust gas in the pressure building cavity of the clutch, and on the premise of good air tightness, when the pressure building cavity is compressed to the minimum volume, the atmospheric negative pressure borne by the piston member in the pressure building cavity is balanced with the thrust of the bearing guide rod borne by the piston member and the elastic force of the return spring in the pressure building cavity, so that the pressure building cavity keeps the minimum volume within a preset time interval, namely, the bearing guide rod keeps the position without return movement within the preset time interval; then, the balance of the piston piece can be broken through continuously or discontinuously opening the exhaust self-checking device, so that the piston piece can slowly push the force bearing guide rod to move towards the direction of the oscillating bar until the force bearing guide rod is in butt joint with the guide rod, and the butt joint process between the force bearing guide rod and the oscillating bar is more convenient and controllable.

The clutch electromechanical device with docking provided in the preferred embodiment of the present invention is configured with the exhaust self-checking device 200, so that the exhaust self-checking method of the AMT clutch electromechanical device can be changed accordingly.

Firstly, a drainage channel is arranged on a clutch electromechanical device in the prior art, one end of the drainage channel is communicated with the atmosphere, and the other end of the drainage channel is communicated with a pipeline between a valve port of a control valve body (an electromagnetic device) of the clutch electromechanical device and a pressure building cavity. Next, the exhaust self-inspection device described above is disposed at the opening position of the flow guide passage. An exhaust channel in the exhaust self-checking device is in butt joint with the drainage channel. And when the exhaust channel is closed in a normal state, the drainage channel is isolated from the external atmosphere. When the exhaust gas needs to be checked, the first flange or the dust cover of the door control device is continuously or non-continuously pressed, so that the exhaust passage 204 is continuously or intermittently opened, that is, at the moment, the drainage passage 107 is continuously or intermittently communicated with the outside atmosphere through the exhaust passage 204, and the gas in the pressure building chamber 101 is exhausted.
