Description

Technical Field

[0001] This utility model relates to the field of gearbox technology, and in particular to a mesh-reinforced aluminum alloy gearbox valve plate. Background Technology

[0002] Automatic transmissions are one of the key components of modern automobiles, achieving automatic gear shifting through an internal hydraulic control system. The transmission valve plate, as the core component of this hydraulic control system, integrates a complex network of oil passages to precisely distribute and guide hydraulic oil, thereby controlling the actions of actuators such as clutches and brakes.

[0003] To achieve complex hydraulic circuit control, transmission valve plates are typically composed of multiple layers of valve plates stacked together. The tight fit and precise positioning between these valve plates are crucial for ensuring the normal operation of the hydraulic system and preventing internal leakage.

[0004] In existing technologies, bolt fastening is commonly used to ensure the sealing and reliable connection between multi-layer valve plates. This connection method requires operators to use specialized tools to tighten a large number of bolts distributed around the valve plate one by one according to a preset sequence and torque. This traditional assembly method is not only cumbersome and time-consuming, but also inefficient during disassembly for maintenance or replacement. Especially on production lines or in confined maintenance spaces, this tool-dependent and time-consuming disassembly and assembly process significantly affects the overall assembly efficiency of the transmission and the convenience of subsequent maintenance.

[0005] Therefore, this utility model proposes a mesh-reinforced aluminum alloy gearbox valve plate to overcome the shortcomings of the prior art. Utility Model Content

[0006] To overcome the above shortcomings, this utility model provides a mesh-reinforced aluminum alloy gearbox valve plate, which aims to improve the problems of complex connection structure, cumbersome disassembly and assembly process and low efficiency in the prior art.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a mesh-reinforced aluminum alloy gearbox valve plate, comprising a lower valve plate with mesh valve holes and an upper valve plate with mesh valve holes; as well as a fixing mechanism and an adjusting mechanism; The fixing mechanism is fixedly connected to the upper surface of the lower valve plate, and the adjusting mechanism is fixedly connected to the upper valve plate via a threaded rod. The adjusting mechanism is used to detachably engage and fix with the fixing mechanism. The fixing mechanism includes a fixing plate fixedly connected to the lower valve plate, a fixing post connected above the fixing plate, a connecting post connected above the fixing post, a fixing block fixedly connected to the top of the connecting post, and a slider slidably connected to the outside of the connecting post, with the slider located between the fixing block and the fixing post. Furthermore, the adjustment mechanism includes a sleeve, a sliding rod is slidably mounted inside the sleeve, an adjustment block is fixedly connected to one end of the sliding rod, and the adjustment mechanism also includes a spring sleeved on the sliding rod, the spring being used to provide a driving force for the adjustment block to elastically extend out of the side wall of the sleeve via the sliding rod; Preferably, a limiting plate is also connected to the sleeve, the limiting plate being used to limit the sliding range of the sliding rod and the spring; Preferably, the lower edge of the fixing block is circumferentially formed with a first slot for engaging with the adjusting block; Preferably, the outer peripheral wall of the fixing block is formed with a first guide slope for squeezing the adjusting block during the pressing down of the sleeve; Preferably, the outer peripheral wall of the slider is formed with a second guide slope for pressing the adjusting block during the pressing down of the sleeve; Preferably, the lower edge of the slider is formed with a second groove for engaging with the adjusting block; Preferably, the slider can reciprocate along the axial direction of the connecting column, and the upward movement of the slider is blocked by the fixed block; Preferably, the adjusting mechanism further includes a threaded rod for detachably connecting the upper valve plate to the sleeve.

[0008] This utility model has the following beneficial effects: 1. This utility model, by setting up a fixing mechanism and an adjusting mechanism that cooperate with each other, utilizes the elastic adjusting block in the adjusting mechanism to quickly engage with the fixing block on the fixing mechanism by pressing. This solves the problem that the valve plate connection in the prior art mostly uses bolt fixing, which is cumbersome to disassemble and assemble and has low efficiency. It achieves quick assembly by hand without tools, which significantly improves production and maintenance efficiency.

[0009] 2. This utility model, by setting a sliding slider on the fixed mechanism and forming a double-layer locking structure with the fixed block, realizes a two-step unlocking operation of pressing down and then pulling up, which solves the problem that traditional buckle structures may be difficult to unlock or prone to accidental loosening, and achieves clear unlocking action, reliable process and effective prevention of misoperation.

[0010] 3. This utility model solves the problem of traditional valve plates requiring additional reinforcement to ensure structural strength, resulting in a bulky structure, by opening mesh valve holes on both the upper and lower valve plates and integrating the valve holes with the reinforcing rib structure. This achieves the goal of enhancing the overall rigidity and pressure resistance of the valve plate while ensuring smooth oil passage, making the structure more compact and lightweight.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Reference Figures 1-5The present invention provides an embodiment of a mesh-reinforced aluminum alloy gearbox valve plate, comprising a lower valve plate 1 and an upper valve plate 2. The lower valve plate 1 and the upper valve plate 2 form the basic frame of the device. Both of them have mesh valve holes 3 inside. The device also includes a fixing mechanism 4 and an adjusting mechanism 5 for quickly connecting and separating the lower valve plate 1 and the upper valve plate 2. The fixing mechanism 4 is fixedly connected to the upper surface of the lower valve plate 1, while the adjusting mechanism 5 is fixedly connected to the upper valve plate 2 through a threaded rod 502. The sleeve 501 of the adjusting mechanism 5 can cover the fixing mechanism 4 to achieve detachable locking and fixing between the two. In detail, the fixing mechanism 4 includes a fixing plate 401, the bottom surface of which is fixedly connected to the upper surface of the lower valve plate 1. A fixing post 402 extends upward from the center of the upper surface of the fixing plate 401. A connecting post 404 is further connected to the top of the fixing post 402. A fixing block 405, serving as the first-stage engagement part, is fixedly connected to the top of the connecting post 404. A slider 403 is slidably connected to the outside of the connecting post 404 and is positioned between the fixing block 405 and the fixing post 402. The slider 403 serves as a linkage component for the second-stage engagement and unlocking. The adjusting mechanism 5 includes a hollow sleeve 501. A sliding rod 503 is slidably installed inside the sleeve 501. An adjusting block 506 is fixedly connected to one end of the sliding rod 503 facing the center of the sleeve 501. The adjusting block 506 can extend or retract from the side wall opening of the sleeve 501. The adjusting mechanism 5 also includes a spring 504 sleeved on the sliding rod 503. One end of the spring 504 abuts against the sliding rod 503, and the other end abuts against the inner wall of the sleeve 501. The spring 504 is used to provide driving force, which makes the adjusting block 506 always maintain an elastic extension of the side wall of the sleeve 501 via the sliding rod 503 when there is no external force, thereby preparing for the subsequent locking action. The lower edge of the fixing block 405 in the fixing mechanism 4 has a first groove, and the outer peripheral wall above the first groove has a first guide slope. The slider 403, which is set at a distance from the fixing block 405, also has a second guide slope on its outer peripheral wall. At the same time, the lower edge of the slider 403 has a second groove for engaging with the adjusting block 506. The first guide slope and the second guide slope provide the adjusting block 506 with a contact surface that is radially pressed during installation and unlocking. The first groove and the second groove provide the adjusting block 506 with two radial engagement positions at different axial heights. In particular, the slider 403 itself can slide freely back and forth along the axial direction of the connecting column 404. The end of the upward sliding stroke of the slider 403 is blocked by the lower surface of the fixing block 405, which is the core linkage part for unlocking. By setting the fixing block 405 and the slider 403 with double guide surfaces and grooves on the fixing mechanism 4, and cooperating with the elastically extendable adjusting block 506 in the adjusting mechanism 5, a complete mechanical structure for quick locking and unlocking of this utility model is formed. The adjusting mechanism 5 also includes a threaded rod 502, which passes through the upper valve plate 2 and is threadedly fixed to the top of the sleeve 501. To ensure the stability of the internal components of the adjusting mechanism 5 during operation and to prevent them from coming loose, a limiting plate 505 is also connected to the sleeve 501. The limiting plate 505 covers the opening of the chamber that accommodates the sliding rod 503 and the spring 504, thereby physically limiting the sliding range of the sliding rod 503 and the spring 504. As a preferred design for the fixing block 405, in order to achieve a stable one-time engagement and smooth installation guidance, the lower edge of the fixing block 405 is circumferentially formed with a first groove for direct engagement with the adjusting block 506. At the same time, above the first groove, the fixing block 405 has a first groove for direct engagement with the adjusting block 506. The outer peripheral wall of the fixed block 405 is formed with a first guide slope for guiding and pressing the adjusting block 506 during installation. As a key structure for realizing two-step unlocking, the outer peripheral wall of the slider 403 is also formed with a second guide slope for guiding and pressing the adjusting block 506 during unlocking. The lower edge of the slider 403 is formed with a second slot for temporarily engaging the adjusting block 506. To realize the linkage function during unlocking, a gap is left between the inner hole of the slider 403 and the connecting post 404, so that the slider 403 can slide back and forth along the axial direction of the connecting post 404. The end point of the upward movement of the slider 403 is blocked by the lower surface of the fixed block 405, thus forming a reliable movement limit.

[0015] Working principle: During installation, the adjusting mechanism 5 is aligned with the fixing mechanism 4 and pressed down. When the adjusting block 506 of the sleeve 501 contacts the first guide slope of the fixing block 405, the adjusting block 506 is compressed and drives the sliding rod 503 to slide backward, compressing the spring 504. When the adjusting block 506 passes the fixing block 405, the elastic restoring force of the spring 504 pushes the sliding rod 503 to reset, so that the adjusting block 506 pops out and is locked into the first slot at the lower edge of the fixing block 405, thereby completing the quick locking of the lower valve plate 1 and the upper valve plate 2. During disassembly, first press the sleeve 501 downwards, the adjusting block 506 disengages from the first slot and continues to descend along the fixing mechanism 4 until it contacts the second guide slope of the slider 403. After being pressed, it pops out again and is locked into the second slot at the lower edge of the slider 403. Then, pull the upper valve plate 2 upwards, and the adjusting block 506 will hook the slider 403 and drive the slider 403 to slide upwards along the connecting post 404. When the top surface of the slider 403 contacts the bottom surface of the fixing block 405, the two parts work together to press the adjusting block 506 backwards so that it is completely retracted into the sleeve 501. At this time, the locking of the fixing block 405 is released. Continue to lift the adjusting mechanism 5 to completely disengage it from the fixing mechanism 4, achieving quick unlocking and separation.
