Description

Technical Field

[0001] This utility model relates to the field of torque converter technology, and in particular to a torque converter gravity distribution device for vehicle torque regulation. Background Technology

[0002] A torque converter is a hydraulic transmission device used in automotive automatic transmissions. Its main functions include torque amplification, lock-up, hydraulic coupling, and automatic clutch engagement. Its structure consists of a pump impeller, turbine, stator, and lock-up clutch. It transmits power through a fluid medium, increasing torque during vehicle start-up and switching to mechanical transmission at high speeds to improve efficiency. The torque converter is installed between the engine and transmission, replacing the traditional clutch to achieve flexible power transmission and buffering, and providing torque amplification and lock-up functions. Maintenance requires regular fluid replacement to prevent abnormal vibration or increased fuel consumption.

[0003] For example, the adjustable torque converter gravity distribution device disclosed in patent publication number CN219472672U has the following key technical points: it includes a pump wheel body, a torque converter housing is fixedly installed on one outer surface of the pump wheel body, a gravity distribution mechanism is fixedly installed on the outer wall of the torque converter housing, and a shock absorption mechanism is fixedly installed on one outer surface of the torque converter housing. This adjustable torque converter gravity distribution device, through its gravity distribution mechanism, reduces the up-and-down swaying of the working oil during low-speed rotation of the torque converter, preventing gravity imbalance and improving the stability of the torque converter. The shock absorption mechanism mitigates the swaying of the rotating shaft during rotation through a spring fixed to the sleeve, thus improving the overall stability of the torque converter during rotation and leading to better application prospects.

[0004] In the aforementioned disclosed prior art, multiple sets of gravity distribution mechanisms composed of springs and other structures are arranged in a circumferential array on the inner wall of the torque converter housing. However, the number of springs in a single gravity distribution mechanism is relatively small, which can easily lead to a decrease in the stability of the gravity distribution mechanism during use. This can cause the working oil to flow up and down in small amounts, resulting in gravity imbalance during equipment use. Furthermore, since the springs are exposed, they are easily damaged, further affecting the stability of the equipment during use. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a torque converter gravity distribution device for vehicle torque regulation.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a torque converter gravity distribution device for vehicle torque regulation, comprising a torque converter housing, an inner ring fixedly connected to the outer contour of the torque converter housing, an outer ring disposed on the outer side of the inner ring, a gravity distribution component arranged in a circumferential array at the gap between the inner ring and the outer ring, and a mounting component disposed on the inner wall of the inner ring.

[0007] As a further description of the above technical solution: The gravity distribution component includes a circumferential array of mounting blocks installed on the outer contour of the outer ring and penetrating through the outer ring. A hexagonal rod is fixedly connected to the bottom of the mounting block. A sleeve is circumferentially mounted on the outer contour of the inner ring. A threaded retaining ring is provided on the inner wall of the sleeve near the top, which is slidably connected to the hexagonal rod for limiting.

[0008] As a further description of the above technical solution: The gravity distribution assembly also includes a connecting plate fixedly connected to the bottom of the hexagonal rod. The inner cavity of the sleeve of the hexagonal rod is provided with a first spring that contacts the bottom of the connecting plate. The bottom of the inner wall of the first spring is fixedly connected with a connecting rod for the first spring to be sleeved. The bottom of the connecting plate is provided with a placement hole extending into the hexagonal rod. The connecting rod is slidably connected to the inner wall of the placement hole. The inner cavity of the placement hole is provided with a second spring that contacts the top of the connecting rod.

[0009] As a further description of the above technical solution: The mounting component includes a sliding groove arranged in a circumferential array at the bottom of the inner wall of the inner ring. A sliding block is provided on the outer contour of the torque converter housing for the sliding groove to limit and slide. An internal threaded bolt is provided on the top of the sliding block and screwed to the torque converter housing.

[0010] As a further description of the above technical solution: The top of the mounting block has an internal hexagonal hole, the outer contour of the mounting block has an external thread, and the outer contour of the outer ring has an internal thread groove arranged in a circumferential array to be screwed into the external thread.

[0011] As a further description of the above technical solution: The inner wall of the sleeve near the top is provided with an inner thread groove for threaded connection.

[0012] This utility model has the following beneficial effects: Compared with existing technologies, this torque converter gravity distribution device for vehicle torque regulation, through the gravity distribution component, causes the mounting block on the inner ring to move the hexagonal rod into the sleeve when the torque converter rotates at low speed, thereby compressing the first spring. Subsequently, when the hexagonal rod moves down, it also compresses the second spring in the placement hole and the connecting rod. Through the elastic action of the first and second springs, the working oil of the torque converter is prevented from sloshing up and down, which would cause poor stability of the torque converter during operation. Furthermore, the presence of the hexagonal rod and the sleeve can protect the two springs, preventing them from causing poor stability of the torque converter due to damage.

[0015] 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.

[0016] Reference Figure 1-4The present invention provides a torque converter gravity distribution device for vehicle torque regulation, including a torque converter housing 1, an inner ring 2 fixedly connected to the outer contour of the torque converter housing 1, an outer ring 3 provided on the outer side of the inner ring 2, a gravity distribution component 4 arranged in a circumferential array at the gap between the inner ring 2 and the outer ring 3, and an mounting component provided on the inner wall of the inner ring 2.

[0017] When the torque converter housing 1 rotates at low speed, multiple gravity distribution components 4 arranged in a circumferential array at the gap between the inner ring 2 and the outer ring 3 buffer and distribute the gravity of the torque converter housing 1. This prevents the torque converter housing 1 from becoming unbalanced and unstable due to the sloshing of the working oil. Furthermore, the shock absorption mechanism on the torque converter housing 1 further increases the stability of the equipment during use. Moreover, the installation of the mounting components allows for quick installation of the inner ring 2, outer ring 3, and gravity distribution components 4, avoiding the difficulty of installing the gravity distribution mechanism in existing technologies.

[0018] The shock absorption mechanism is existing technology as described in the prior art document and is not shown in the figure.

[0019] The gravity distribution assembly 4 includes mounting blocks 5 arranged in a circumferential array on the outer contour of the outer ring 3 and penetrating through the outer ring 3. A hexagonal rod 6 is fixedly connected to the bottom of the mounting blocks 5. Sleeves 7 are arranged in a circumferential array on the outer contour of the inner ring 2. A threaded retaining ring 8, which is slidably connected to the hexagonal rod 6, is provided on the inner wall of the sleeve 7 near its top. The gravity distribution assembly 4 also includes a connecting plate 9 fixedly connected to the bottom of the hexagonal rod 6. A first spring 10, which contacts the bottom of the connecting plate 9, is provided inside the sleeve 7 of the hexagonal rod 6. A spring for the first spring 10 is fixedly connected to the bottom of the inner wall of the first spring 10. The connecting rod 11 is sleeved with spring 10. The bottom of the connecting plate 9 has a placement hole 12 extending into the hexagonal rod 6. The connecting rod 11 is slidably connected to the inner wall of the placement hole 12. The inner cavity of the placement hole 12 is provided with a second spring 13 that contacts the top of the connecting rod 11. The top of the mounting block 5 has an internal hexagonal hole 51. The outer contour of the mounting block 5 has an external thread 52. The outer contour of the outer ring 3 has a circumferential array of internal thread grooves 53 that are screwed into the external thread 52. The inner wall of the sleeve 7 near the top has an internal thread groove 81 for screwing into the internal thread groove 81.

[0020] When the torque converter rotates at low speed, the mounting block 5 on the inner ring 2 drives the hexagonal rod 6 to move into the sleeve 7. This causes the hexagonal rod 6, which passes through the threaded retaining ring 8, to drive the connecting plate 9 deeper into the sleeve 7, thereby compressing the first spring 10. Subsequently, as the hexagonal rod 6 moves downward, it also drives the connecting rod 11 into the placement hole 12. This causes the second spring 13 in the placement hole 12 to compress the connecting rod 11. Through the elastic action of the compressed first spring 10 and second spring 13, the working oil of the torque converter is prevented from sloshing up and down, thus preventing the torque converter from becoming unstable during operation. The presence of the angle rod 6 and sleeve 7 protects the two springs, preventing them from causing instability in the torque converter due to damage. After the first spring 10 and the second spring 13 are damaged, the operator can insert a hex wrench into the internal hexagonal hole 51 to separate the external thread 52 from the internal thread groove 53. When the mounting block 5 rotates, it also rotates the hexagonal rod 6, causing the hexagonal rod 6 to drive the threaded retaining ring 8 to separate it from the internal thread groove 81. This allows the mounting block 5, hexagonal rod 6, threaded retaining ring 8, and connecting plate 9 to be removed. Then, the first spring 10 and the second spring 13 can be replaced.

[0021] The mounting components include sliding grooves 14 arranged in a circumferential array at the bottom of the inner wall of the inner ring 2, and sliding blocks 15 provided on the outer contour of the torque converter housing 1 for the sliding grooves 14 to limit and slide. The top of the sliding block 15 is provided with an internal threaded bolt 16 that is screwed to the torque converter housing 1.

[0022] When installing the inner ring 2, outer ring 3, and gravity distribution assembly 4, the workers insert the dovetail-shaped sliding block 15 into the dovetail-shaped sliding groove 14, so that the inner ring 2, outer ring 3, and gravity distribution assembly 4 are initially installed on the torque converter housing 1. Then, the workers can easily use a hex wrench to screw the internal thread bolt 16 to the torque converter housing 1, thus completing the rapid installation of the inner ring 2, outer ring 3, and gravity distribution assembly 4, which greatly increases the work efficiency of the workers.

[0023] Working principle: First, the operator inserts the dovetail-shaped sliding block 15 into the dovetail-shaped sliding groove 14, so that the inner ring 2, outer ring 3, and gravity distribution assembly 4 are initially installed on the torque converter housing 1. Then, the operator uses a hex wrench to screw the internal thread bolt 16 to the torque converter housing 1, completing the installation of the inner ring 2, outer ring 3, and gravity distribution assembly 4. When the torque converter rotates at low speed, the mounting block 5 on the inner ring 2 drives the hexagonal rod 6 to move into the sleeve 7. This causes the hexagonal rod 6, which passes through the threaded retaining ring 8, to drive the connecting plate 9 deeper into the sleeve 7, thereby compressing the first spring 10. Subsequently, as the hexagonal rod 6 moves downward, it also drives the connecting rod 11 into the placement hole 12, causing the second spring 13 in the placement hole 12 to compress the connecting rod 11. Through the elastic action of the compressed first spring 10 and the second spring 13, the working oil of the torque converter is prevented from sloshing up and down, which would cause poor stability during operation. Furthermore, the presence of the hexagonal rod 6 and the sleeve 7 protects the two springs, preventing them from causing poor stability of the torque converter due to damage, thus increasing the stability of the equipment during operation.

[0024] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
