Description

Technical Field

[0001] The invention relates to the technical field of leaf spring vibration reduction, and in particular to a gear transmission vibration reducer based on a leaf spring. Background Art

[0002] At present, automobile suspension is a device that elastically connects the frame and axle in the car. It is generally composed of vibration absorbing springs, guide mechanisms, shock absorbers and other components. Its main task is to ease the impact transmitted to the frame from uneven roads to improve the comfort of riding.

[0003] The automobile leaf spring is the most traditional elastic element in the automobile suspension system. It is widely used due to its good reliability, simple structure, short manufacturing process, low cost and greatly simplified structure. Automobile leaf springs are generally composed of several pieces of alloy spring steel of unequal lengths to form a group of spring beams with similar strength. In the suspension system, in addition to playing a buffering role, when it is placed longitudinally in the car and one end is connected to the frame with a fixed hinge, it can be responsible for transmitting all forces and torques in all directions, as well as determining the trajectory of wheel movement and playing a guiding role.

[0004] However, when the existing leaf spring buffers the force exceeding its own vibration resistance limit, it is difficult to further buffer it. Under normal circumstances, the vibration energy cannot be converted and buffered in time, resulting in poor vibration reduction effect. Summary of the invention

[0005] The purpose of this section is to summarize some aspects of embodiments of the present invention and briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section and the specification abstract and the invention title of this application to avoid blurring the purpose of this section, the specification abstract and the invention title, and such simplifications or omissions cannot be used to limit the scope of the present invention.

[0010] The extension member comprises an extension bracket arranged at the lower end of one of the leaf spring brackets and an auxiliary hanging member rotatably connected to the lower end of the extension bracket.

[0011] As a preferred solution of the leaf spring-based gear transmission shock absorber described in the present invention, the auxiliary hanging component includes a first extension sleeve rotatably connected to the lower end of the extension bracket, a second extension sleeve slidably connected to the first extension sleeve, and a rotating frame body arranged at the end of the second extension sleeve, the rotating frame body is provided with a hanging plate, the hanging plate is provided with a hanging ring, the hanging ring is hung around the leaf spring plate, and the transmission box is arranged on the rotating frame body.

[0012] As a preferred solution of the leaf spring-based gear-driven shock absorber described in the present invention, the adjusting component includes a rotating ring coaxially arranged on the first transmission gear, an annular clamping plate is arranged around the outer ring of the rotating ring, a plurality of blocking plates are arranged on the inner side of the annular clamping plate, the blocking plates are arranged at an angle, and a locking piece is provided on the rotating ring.

[0013] As a preferred solution of the leaf spring-based gear transmission shock absorber described in the present invention, the locking member includes a slot provided on the outer wall of the rotating ring, a rotating plate rotatably connected in the slot, a support rod rotatably connected in the slot, and an elastic member arranged between the slot and the rotating plate, a through hole is provided on the rotating plate, and a matching rod matching the through hole is provided at the end of the support rod. After the rotating ring rotates, the centrifugal force is used to drive the rotating plate to rotate up and get stuck between the two blocking plates.

[0014] As a preferred solution of the leaf spring-based gear transmission shock absorber described in the present invention, a spring is provided between the first extension sleeve and the second extension sleeve, an outer ring is provided on the annular clamping plate, an external thread is provided on the outer side of the outer ring, a matching cartridge is threadedly connected to the outer ring, the matching cartridge is slidably connected to the outer wall of the second extension sleeve, one end of the spring is connected to the first extension sleeve, and the other end is connected to the matching cartridge.

[0015] As a preferred solution of the leaf spring-based gear-driven shock absorber described in the present invention, wherein: a rack is meshed on the first transmission gear, a buffer rod is arranged at the upper end of the rack, the buffer rod extends upward from the hanging plate, the upper end of the buffer rod abuts against the lower end of the leaf spring plate, and a buffer head is arranged at the upper end of the buffer rod.

[0016] As a preferred solution of the leaf spring-based gear-driven shock absorber of the present invention, a storage cavity is provided in the annular card plate, a rotating shaft is provided at one end of the baffle plate extending into the storage cavity, and a driving component for driving the baffle plate to rotate is provided in the annular card plate;

[0017] The driving component includes a connecting ring arranged outside each rotating shaft, a connecting ring arranged on the rotating shaft, and a connecting rod extending from the side wall of the connecting ring. A driven connecting rod is hinged between the lower ends of each two connecting rods, and a motor connected to the rotating shaft is provided on the annular clamping plate.

[0018] The beneficial effects of the present invention are as follows: when the vibration of the leaf spring plate is transmitted downward, the rack will be pressed down, and the rotation of the rack will drive the rotation of the first transmission gear, and the rotation of the first transmission gear will drive the synchronous rotation of the second transmission gear. When the rotation rate of the second transmission gear is accelerated, several rotating plates will be rotated up under the action of centrifugal force. When the angle of the rotating plate after being rotated is opposite to the angle of the blocking plate, the rotating plate will be stuck in the gap between each two blocking plates, and the rotating plate will continue to rotate, thereby driving the rotation of the annular clamping plate, and then driving the outer ring to rotate. The outer ring drives the matching cartridge to rotate under the action of the thread, because the matching cartridge can only slide along the length direction of the second extension sleeve, and then the matching cartridge will move away from the second extension sleeve, thereby stretching the spring, and then the external vibration can be further reduced. At this time, the spring can also be further extended to further enhance the vibration reduction effect. This mode is used in vibration conditions with larger vibrations, and when this setting is used, when the leaf spring plate is subjected to vibrations exceeding its deformation capacity, the spring between the first extension sleeve and the second extension sleeve will play a role in increasing the buffer.

[0019] When the blocking plate is rotated, if the angle of the rotating plate after it is rotated is not opposite to the angle of the blocking plate, the rotating plate will continuously collide with the blocking plate after it is rotated. Because the blocking plate has a certain flexibility, it will transmit the vibration outward. The collision with the blocking plate will cause the annular clamping plate to rotate slightly, thereby pulling the spring slightly outward, thereby achieving buffering. This mode is suitable for small and multiple vibrations.

[0020] This setting has two different buffering and vibration reduction response methods, and the entire adjustment is automatic, so that different vibration modes can be adjusted according to different vibration effects. BRIEF DESCRIPTION OF THE DRAWINGS

An adjustment member 300 is provided between the extension member 103 and the first transmission gear 202.

[0042] Furthermore, in this embodiment, the auxiliary hanging member 104 includes a first extension sleeve 104a rotatably connected to the lower end of the extension bracket 103a, a second extension sleeve 104b slidably connected to the first extension sleeve 104a, and a rotating frame body 104c arranged at the end of the second extension sleeve 104b, a hanging plate 104d is arranged on the rotating frame body 104c, a hanging ring 104e is arranged on the hanging plate 104d, and the hanging ring 104e is hung around the leaf spring plate 102.

[0044] In this embodiment, the adjustment component 300 includes a rotating ring 301 coaxially arranged on the first transmission gear 202, an annular clamping plate 302 is arranged around the outer ring 402 of the rotating ring 301, a plurality of blocking plates 303 are arranged on the inner side of the annular clamping plate 302, the blocking plates 303 are arranged at an angle, and a locking member is provided on the rotating ring 301.

An external thread is provided on the outer side of the outer ring 402, and a matching cartridge 403 is threadedly connected to the outer ring 402. The matching cartridge 403 can only slide along the length direction of the first extension sleeve 104a. One end of the spring 401 is connected to the first extension sleeve 104a, and the other end is connected to the matching cartridge 403.

[0047] A rack 404 is meshed with the first transmission gear 202 , and a buffer rod 405 is provided at the upper end of the rack 404 . The buffer rod 405 extends upward from the hanging plate 104 d , and the upper end of the buffer rod 405 abuts against the lower end of the leaf spring plate 102 .

[0048] Preferably, the thickness ratio of the first transmission gear 202 to the thickness of the second transmission gear 203 is 3:1, so that when the leaf spring plate 102 is subjected to downward vibration, the vibration is transmitted to the buffer rod 405, and the buffer rod 405 drives the rack 404 to slide. Preferably, the teeth on the rack 404, the first transmission gear 202 and the second transmission gear 203 are all inclined, so as not to hinder the sliding and rotation of the first transmission gear 202.

[0049] Preferably, a storage cavity 407 is opened in the annular clamping plate 302, and a rotation groove is opened at each corresponding baffle plate 303, and the baffle plate 303 is arranged in the rotation groove, and a rotating shaft 406 is arranged at one end of the baffle plate 303 extending into the storage cavity 407, and a driving component 500 for driving the baffle plate 303 to rotate is arranged in the annular clamping plate 302.

[0050] In this embodiment, the driving component 500 includes a connecting ring 501 arranged outside each rotating shaft 406, and the connecting ring 501 is connected to the outer wall of the annular clamping plate 302 by bolts, and then a connecting ring 502 is also connected to the rotating shaft 406, and a connecting rod 503 extends downward from the side wall of the connecting ring 502, and the connecting rod 503 extends downward and will rotate with the rotation of the rotating shaft 406, and then a driven connecting rod 504 is hinged between the lower ends of each two connecting rods 503, and both ends of the driven connecting rod 504 are hinged, so that only one rotating shaft 406 needs to be driven to rotate to drive the rotation of other rotating shafts 406.

[0051] A clamping block 505 is provided at one end of the rotating shaft 406 close to the connecting ring 502. The clamping blocks 505 are symmetrically arranged on the rotating shaft 406, and two clamping blocks 505 are arranged in the radial diameter direction of the rotating shaft 406. At the same time, a clamping groove 304 cooperating with the clamping block 505 is provided on the connecting ring 502. At the same time, the angle between the connecting line of the two clamping blocks 505 and the length direction line of the connecting rod 503 is between 45° and 50°. A bracket 506 is also provided on the annular clamping plate 302, and a motor 507 is provided on the bracket 506, so as to utilize The motor 507 can be used to control the rotation of the rotating shaft 406. When the motor 507 drives the rotating shaft 406 to rotate, it will synchronously drive the rotation of the connecting rod 503. The rotation of the rotating rod 503 will push the driven connecting rod 504 at the lower end to slide in a straight line. The sliding of the driven connecting rod 504 will drive the rotation of the next rotating rod 503, and so on. The rotation of all the rotating rods 503 is realized, thereby driving the rotation of several rotating shafts 406, thereby realizing the rotation of the blocking plate 303, so that the blocking plate 303 changes direction after rotation.

[0052] Preferably, a vibration sensor is provided on the second extension sleeve 104b, and the vibration sensor controls the rotation of the motor 507 through a control circuit.

[0053] Operation process: When the vibration of the leaf spring plate 102 is transmitted downward, it will press down the rack 404. After the rack 404 rotates, it will drive the rotation of the first transmission gear 202, and the rotation of the first transmission gear 202 will drive the synchronous rotation of the second transmission gear 203. When the rotation rate of the second transmission gear 203 is accelerated, it will rotate a plurality of rotating plates 305 under the action of centrifugal force. When the angle of the rotating plate 305 after rotating is opposite to the angle of the blocking plate 303, the rotating plate 305 will be stuck in the gap between every two blocking plates 303, and the rotating plate 305 will continue to rotate, thereby driving the rotation of the annular clamping plate 302, and then driving the outer ring 402 to rotate. Under the action of the thread, the outer ring 402 drives the matching cartridge 403 to rotate. Because the matching cartridge 403 can only slide along the length direction of the second extension sleeve 104b, the matching cartridge 403 will move away from the second extension sleeve 104b, thereby extending the spring 401, thereby further reducing the external vibration. At this time, the spring 401 can also be further extended to further enhance the vibration reduction effect. This mode is used in vibration conditions with larger vibrations, and when the leaf spring plate 102 is subjected to vibrations exceeding its deformation capacity, the spring 401 between the first extension sleeve 104a and the second extension sleeve 104b will play a role in increasing the buffering.

[0054] When the blocking plate 303 is rotated, when the angle of the rotating plate 305 after rotation is not opposite to the angle of the blocking plate 303, when the rotating plate 305 is rotated, it will continuously collide with the blocking plate 303. Because the blocking plate 303 has a certain flexibility, it will transmit the vibration outward. The collision with the blocking plate 303 will cause the annular clamping plate 302 to rotate slightly, thereby pulling the spring 401 slightly outward, thereby achieving buffering. This mode is suitable for small and multiple vibrations.

[0055] This setting has two different buffering and vibration reduction response methods, and the entire adjustment is automatic, so that different vibration modes can be adjusted according to different vibration effects.
