Description

Technical Field

[0001] The present invention relates to the technical field of turbochargers, and in particular to an adaptively regulating turbocharger actuator. Background Art

[0002] The turbocharger uses the energy of exhaust gas to drive the turbine to work. The high-speed rotation of the turbine drives the coaxial compressor impeller to work, thereby increasing the intake pressure and the intake volume. When the engine exhaust energy is sufficient, the excess exhaust energy of the turbocharger needs to be discharged by opening the bypass valve of the supercharger to avoid the problem of supercharger overspeed. At present, the opening and closing of the bypass valve of the turbocharger are generally controlled by a pneumatic actuator, which is mainly composed of an upper shell and a lower shell. A diaphragm is connected between the upper and lower shells. The diaphragm separates the upper and lower shells into two independent spaces. A pull rod and a pull rod cap are installed in the lower shell. The pull rod cap is fixed to the diaphragm. When the exhaust gas enters the upper shell, the diaphragm pushes the pull rod outward under the action of air pressure. The pull rod acts on the execution structure of the bypass valve, so that the bypass valve is opened. After the air pressure inside the upper shell drops, the pull rod is reset under the action of the spring.

[0003] When the diaphragm moves downward under the action of air pressure, the exhaust hole usually starts on the outer wall of the lower shell. When the rod cap and the diaphragm move downward, the air inside the lower shell is discharged. Under normal circumstances, the setting of the exhaust hole can meet the outward movement of the rod to realize the opening and closing of the bypass valve. However, once the exhaust gas discharged by the engine in a short period of time is too high, a large amount of excess exhaust gas will flow into the upper shell in a short period of time, which will cause the internal pressure of the upper shell to suddenly increase. At this time, the diaphragm and the rod cap have a strong tendency to move downward. However, at this time, the air inside the lower shell cannot be discharged from the exhaust hole in time, so the air that cannot be discharged will react on the rod cap, forming an obstacle to it, and then the rod cannot move outward quickly to control the bypass valve to open. The exhaust gas inside the supercharger cannot be quickly and effectively released, which will cause an overspeed problem. In view of the above situation, the present invention proposes an adaptive adjustment turbocharger actuator. Summary of the invention

[0007] Preferably, the actuator includes a gear ring fixed on the outer wall of the inner straight cylinder and a linear rack arranged inside the lower shell and meshing with the gear ring, wherein a base is fixedly installed at a position inside the lower shell corresponding to the position of the linear rack, and the linear rack is installed on the base along its length direction and guided by sliding, and the rotating cylinder is rotated relative to the lower shell by driving the linear rack to slide relative to the base.

A spring is arranged on the periphery of the actuator pull rod, one end of the spring is fixedly connected to the pull rod cap, and the other end is connected to the sliding plate; the sliding plate slides along its axial direction inside the inner straight cylinder, and when the inner straight cylinder rotates relative to the lower shell body to increase the connecting area between the first arc groove and the second arc groove, the sliding plate slides inside the inner straight cylinder toward its bottom.

[0010] Preferably, two clamping beads are integrally formed and connected on the outer wall of the sliding plate, and a spiral limiting guide groove is opened on the inner wall of the inner straight cylinder at the position corresponding to each clamping bead, and the spiral limiting guide groove extends from the top end to the bottom end of the inner straight cylinder along the axial direction of the inner straight cylinder, and the clamping beads are embedded in the corresponding spiral limiting guide groove and slidably connected therewith; A protrusion is integrally formed and connected to the inner side of the sliding plate at a position corresponding to the actuator pull rod passing therethrough, and a guide groove matched with the protrusion is formed on the circumferential surface of the actuator pull rod, and the guide groove is distributed along the axial direction of the actuator pull rod.

[0011] Preferably, when the sliding plate slides from the top to the bottom of the inner straight cylinder, the rotation angle of the inner straight cylinder just maximizes the communication area between the first arc-shaped groove and the second arc-shaped groove.

A second arc groove is provided through the rotating drum at a position corresponding to each first arc groove. The first arc groove and the second arc groove cooperate to form an exhaust hole structure of variable size. The electric telescopic rod is controlled by a wind speed sensor at the air inlet nozzle to drive the rotating drum to rotate. When the exhaust gas inside the supercharger suddenly increases, the greater the rotation angle of the rotating drum, the greater the connecting area between the first arc groove and the second arc groove, and the faster the gas discharge speed inside the lower shell body, thereby reducing the resistance of the gas inside the lower shell body to the pull rod cap, so that the bypass valve of the supercharger can be opened quickly.

[0014] (2) In addition, the rotating drum in the present invention can also drive the sliding plate to slide axially inside it during the rotation process, thereby driving the spring to move as a whole, so that the compression of the pull rod cap on the spring when it moves downward is reduced, and the obstruction of the spring on the pull rod cap is reduced accordingly, further accelerating the rapid extension of the actuator pull rod. When the gas pressure inside the upper shell decreases or disappears, the reverse rotation of the rotating drum will drive the spring to move upward for reset, and the spring itself will also restore its deformation. The pull rod cap is reset under the action of the spring movement and deformation. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0017] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. The components of the embodiments of the present invention generally described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely represents the selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative work belong to the scope of protection of the present invention.

[0018] This embodiment proposes an adaptive adjustment turbocharger actuator, such as Figures 1 to 8As shown, it includes an upper shell 1 and a lower shell 2, the top of the upper shell 1 is connected to an air inlet nozzle 3, and the air inlet nozzle 3 is connected to the compressor outlet of the supercharger. A flexible diaphragm 7 is arranged between the upper shell 1 and the lower shell 2, and the outer edge of the flexible diaphragm 7 is pressed on the connection between the upper shell 1 and the lower shell 2, so as to separate the upper shell 1 and the lower shell 2 into two independent cavities. The actuator rod 5 passes through the interior of the lower shell 2 and is fixedly connected with a rod cap 6, and the rod cap 6 is fixedly connected with the flexible diaphragm 7. A high-speed engine will produce more exhaust gas. In addition to driving the turbine to do work, if there is excess exhaust gas, then this part of the exhaust gas needs to be discharged. This part of the exhaust gas first enters the upper shell 1 through the air inlet nozzle 3. As the pressure inside the upper shell 1 gradually increases, the rod cap 6 will move downward under the action of pressure, and then drive the actuator rod 5 to extend to drive the bypass valve on the supercharger to open, and finally discharge the exhaust gas inside the supercharger.

[0019] During the downward movement of the pull rod cap 6, the existing practice is to open an exhaust hole on the outer wall of the lower shell 2 to discharge the gas inside it, ensuring that the pull rod cap 6 can move downward smoothly. However, if the exhaust gas generated by the high-speed rotation of the engine suddenly increases, and the energy of these exhaust gases can not only meet the work of the supercharger, but also a large amount of exhaust gas enters the upper shell 1 through the air intake nozzle 3, then the pressure on the pull rod cap 6 will increase, and its downward movement speed will also increase. However, due to the effect of gas inertia, the gas inside the lower shell 2 will not have time to be discharged from the exhaust hole, then the gas inside the lower shell 2 will become an obstacle to the downward movement of the pull rod cap 6, and it will cause the actuator pull rod 5 to fail to open the bypass valve in time, and the exhaust gas inside the supercharger cannot be released quickly, which will cause the supercharger to overspeed, causing damage to the supercharger and even the engine, affecting the acceleration performance of the vehicle.

[0020] In view of this, the present invention controls the opening size of the exhaust hole on the outer wall of the lower shell 2 according to the amount of exhaust gas entering the interior of the upper shell 1, so that the air inside the lower shell 2 can be discharged in time, ensuring that the actuator rod 5 can smoothly open the bypass valve of the supercharger. Specifically, a wind speed sensor 9 is installed at the connection between the air inlet nozzle 3 and the upper shell 1, and the wind speed sensor 9 is used to collect the exhaust gas speed entering the interior of the upper shell 1 (the exhaust gas speed also determines the amount of exhaust gas entering the interior of the upper shell 1), so as to adjust the size of the exhaust hole on the outer wall of the lower shell 2, and the present invention also controls the opening size of the exhaust hole on the outer wall of the lower shell 2 according to the amount of exhaust gas entering the interior of the upper shell 1. The exhaust holes on the body 2 are redesigned as follows: a plurality of first arcuate grooves 11 are formed through the bottom wall of the lower shell 2, a rotating drum 4 is rotatably mounted at the center of the bottom of the lower shell 2, a second arcuate groove 16 is formed through the rotating drum 4 at a position corresponding to each first arcuate groove 11, the first arcuate groove 11 and the second arcuate groove 16 have the same specifications, the gas inside the lower shell 2 is discharged to the outside through the first arcuate groove 11 and the second arcuate groove 16 in turn, which is equivalent to the first arcuate groove 11 and the second arcuate groove 16 cooperating to form an exhaust hole structure with changeable size.

[0021] In the above scheme, the connecting area of ​​the first arc groove 11 and the second arc groove 16 is changed by driving the rotating drum 4 to rotate relative to the lower shell 2, and the rotation of the rotating drum 4 is realized by an actuator arranged inside the lower shell 2. The actuator establishes a signal connection with the wind speed sensor 9. The wind speed sensor 9 collects the exhaust gas speed signal entering the upper shell 1 in real time, and converts the collected signal into an electrical signal and sends it to the controller. The controller controls the actuator to drive the rotating drum 4 to rotate. When the exhaust gas speed collected by the wind speed sensor 9 increases (which means that the exhaust gas volume is large), the rotating drum 4 rotates to increase the connecting area of ​​the first arc groove 11 and the second arc groove 16, thereby accelerating the discharge of air inside the lower shell 2. On the contrary, when the exhaust gas speed collected by the wind speed sensor 9 decreases, the connecting area of ​​the first arc groove 11 and the second arc groove 16 decreases, so that the lower shell 2 is isolated from the outside as much as possible, and external debris is prevented from entering the lower shell 2 through the first arc groove 11 and the second arc groove 16. In actual application, three first arc grooves 11 are provided at the bottom of the lower shell 2, and three corresponding second arc grooves 16 are also provided. The two ends of the first arc groove 11 are circular. In the initial state, the positions of the first arc groove 11 and the second arc groove 16 are as follows: Figure 5 As shown, at this time, the bottom of the lower shell 2 is equivalent to having three circular air holes. When the entire actuator is not working, the lower shell 2 is connected to the outside through the three air holes with smaller diameters to avoid excessive contact between the inside of the lower shell 2 and the outside.

[0022] As a preferred embodiment, the rotating cylinder 4 in this embodiment includes an inner straight cylinder 41 and an outer conical cylinder 42, wherein a limited position holder 18 is integrally formed on the outer wall of the inner straight cylinder 41, and the inner straight cylinder 41 is rotatably connected to the lower shell 2 through the limited position holder 18. The existence of the limited position holder 18 enables the inner straight cylinder 41 and the lower shell 2 to always maintain relative rotation, and remain relatively stationary in the axial direction. The bottom of the outer conical cylinder 42 is integrally connected to the inner straight cylinder 41, and the top is radially extended outward to form a ring plate, and a plurality of second arc grooves 16 are evenly distributed on the ring plate in an annular shape, and the ring plate is matched and connected to the bottom of the lower shell 2. Furthermore, the actuator in this embodiment includes a gear ring 12 fixed on the outer wall of the inner straight cylinder 41 and a linear rack 13 arranged inside the lower shell 2 and meshing with the gear ring 12, wherein a base 15 is fixedly installed at a position inside the lower shell 2 corresponding to the linear rack 13, and the linear rack 13 is installed on the base 15 along its length direction. An electric telescopic rod 14 is fixedly installed on the base 15, and the movable end of the electric telescopic rod 14 is connected to the linear rack 13. The electric telescopic rod 14 is controlled by the wind speed sensor 9 to drive the linear rack 13 to slide relative to the base 15, so that the rotating drum 4 rotates relative to the lower shell 2, and the telescopic length of the electric telescopic rod 14 is set to be proportional to the wind speed data signal detected by the wind speed sensor 9 (of course, the control of the electrical part can adopt the currently available technology), and the connecting area of ​​the first arc groove 11 and the second arc groove 16 is changed by controlling the telescopic length of the electric telescopic rod 14.

[0023] Due to the existence of the inner straight tube 41, the actuator rod 5 in this embodiment is arranged to penetrate the inner straight tube 41, and a rod cap 6 is fixed to one end of the actuator rod 5 extending to the inside of the lower shell 2. The outer periphery of the rod cap 6 is connected to a flexible diaphragm 7, and the outer edge of the flexible diaphragm 7 is pressed at the connection between the upper shell 1 and the lower shell 2. The end of the inner straight tube 41 facing the inner side of the lower shell 2 is open, and a sliding plate 10 matching the inner diameter is arranged inside the inner straight tube 41. A spring 8 is arranged on the outer periphery of the actuator rod 5, and one end of the spring 8 is fixedly connected to the rod cap 6, and the other end is connected to the sliding plate 10. When the rod cap 6 moves downward under the action of the gas pressure inside the upper shell 1, the spring 8 is gradually compressed. When the gas pressure inside the upper shell 1 decreases or disappears, the rod cap 6 is reset under the reaction of the spring 8.

[0024] The setting of the spring 8 can certainly realize the resetting of the tie rod cap 6, but when there is a lot of exhaust gas inside the supercharger that needs to be discharged in time, the tie rod cap 6 first drives the actuator tie rod 5 to extend quickly to drive the bypass valve to open, and the resistance to the downward movement of the tie rod cap 6 includes not only the reaction force of the gas inside the lower shell 2, but also the obstruction of the spring 8 to the tie rod cap 6, and as the tie rod cap 6 moves further downward, the resistance of the spring 8 to the tie rod cap 6 will further increase, all of which delay the extension speed of the actuator tie rod 5, thereby preventing the bypass valve from opening quickly. In order to reduce the resistance of the spring 8 to the movement of the pull rod cap 6, the present embodiment chooses to slide the sliding plate 10 inside the inner straight cylinder 41, and the sliding plate 10 slides along its axial direction inside the inner straight cylinder 41. When the inner straight cylinder 41 rotates relative to the lower shell 2 to increase the communication area between the first arc groove 11 and the second arc groove 16, the gas inside the lower shell 2 can be discharged faster, and the sliding plate 10 slides toward its bottom inside the inner straight cylinder 41. Although the pull rod cap 6 acts on the spring 8 to compress it, the spring 8 can also move downward axially with the sliding plate 10. Therefore, the resistance of the spring 8 to the pull rod cap 6 is greatly reduced, and the resistance of the spring 8 to the pull rod cap 6 is reduced. In addition, the air inside the lower shell 2 is quickly discharged, and the resistance of the entire pull rod cap 6 is reduced. Therefore, it can ensure that the actuator pull rod 5 is quickly extended to drive the bypass valve to open.

[0025] In order to enable the sliding plate 10 to slide along the axial direction inside the inner straight cylinder 41 when the inner straight cylinder 41 rotates, the present embodiment selects to integrally form two clamping beads 21 on the outer wall of the sliding plate 10, and a spiral limiting guide groove 17 is opened on the inner wall of the inner straight cylinder 41 at the position corresponding to each clamping bead 21. The spiral limiting guide groove 17 extends from the top end to the bottom end of the inner straight cylinder 41 along the axial direction of the inner straight cylinder 41, and the clamping bead 21 is embedded in the corresponding spiral limiting guide groove 17 and slidably matched therewith. Since the actuator rod 5 needs to penetrate the sliding plate 10 to perform reciprocating linear motion, the sliding plate 10 and the actuator rod 5 need to be relatively stationary in the circumferential direction, so as to ensure that the sliding plate 10 slides axially inside the inner straight cylinder 41. For this purpose, a protrusion 19 is integrally formed and connected to the inner side of the sliding plate 10 at a position corresponding to the actuator rod 5 penetrating therewith, and a guide groove 20 matched with the protrusion 19 is formed on the circumferential surface of the actuator rod 5. The guide groove 20 is distributed along the axial direction of the actuator rod 5. When the inner straight cylinder 41 rotates, the spiral limiting guide groove 17 on the inner wall thereof acts on the corresponding card bead 21 on the circumferential surface of the sliding plate 10, and the entire sliding plate 10 cannot rotate due to the cooperation between the protrusion 19 and the guide groove 20, and therefore it slides along the axial direction of the inner straight cylinder 41. Since the maximum rotation angle of the inner straight cylinder 41 is fixed (i.e., the maximum rotation angle is reached when the inner straight cylinder 41 rotates so that the first arc groove 11 and the second arc groove 16 completely overlap), the downward sliding distance of the sliding plate 10 in the inner straight cylinder 41 depends on the spiral limiting guide groove 17. The projection points of the top and bottom ends of the spiral limiting guide groove 17 on the bottom of the inner straight cylinder 41 are set to A and B respectively. The included angle between the centers of A and B at the bottom of the inner straight cylinder 41 is α. The angle α is the same as the angles of the first arc groove 11 and the second arc groove 16. When the rotation of the inner straight cylinder 41 just maximizes the connecting area between the first arc groove 11 and the second arc groove 16, the sliding plate 10 just slides from the top to the bottom in the inner straight cylinder 41.

[0026] In addition, since the sliding plate 10 reciprocates inside the inner straight cylinder 41, in order to prevent the card bead 21 from slipping off the top of the spiral limiting guide groove 17 and causing the sliding plate 10 to detach from the inner straight cylinder 41, the present embodiment also has a limiting plate 22 integrally formed at the top of the inner straight cylinder 41 extending toward the inner side thereof for limiting the sliding plate 10.
