Description

Technical Field

[0001] The utility model relates to the technical field of transmission boxes, in particular to an AT automatic transmission box support structure. Background Art

[0002] The support structure of an AT automatic transmission mainly refers to its constituent components and how these components work together to support the operation of the entire transmission.

[0003] Disadvantages: Gearboxes are widely used in the mining industry, and the quality requirements are becoming increasingly stringent. Casting defects are common in integrally molded brackets. Under harsh operating conditions, the structural strength of general brackets is insufficient, which can easily damage gearbox components. Furthermore, the cost of small-batch mold opening is high, and the components are often easily damaged. Underground mining vehicles operate in extremely harsh conditions, with severe wear and impact on various components. In particular, relative movement occurs between the vehicle frame and the gearbox connection. To ensure the position of the gearbox in the transmission system, a support device must be installed to connect to the vehicle frame.

[0004] To address these shortcomings, prior art (application number: 202322251576.2, Chinese patent with an authorization announcement date of April 26, 2024) discloses a gearbox support structure. This gearbox support structure features a simple design, making the bracket assembly extremely easy to install during the complete installation of mining equipment. Due to its welded design, the mounting bracket assembly is lightweight and easy to lift, making it suitable for low-cost, small-batch production. The U-shaped hole design on the gearbox mounting base eliminates the difficulty of installing the mounting hole due to travel vibrations. After lifting, it is directly bolted to the vehicle frame. This designed bracket assembly reduces damage to the gearbox body from impact and wear, eliminating potential quality risks to the gearbox body caused by wear and impact. Furthermore, the welded design offers strong compatibility, stable and reliable support, and can be used to install a variety of gearbox models.

[0005] The existing technology utilizes the design of a U-shaped hole on the gearbox mounting base and fixes it directly to the vehicle frame with bolts, which can reduce the damage to the gearbox body caused by impact and wear. However, relying solely on the bracket assembly to support the gearbox results in poor support for the gearbox. This makes it easy for the gearbox to produce large-scale non-directional jumps under harsh working conditions, causing the flywheel housing and clutch housing connected to the gearbox to bear large torque, thereby affecting the normal service life of the gearbox.

[0006] Therefore, we proposed that the AT automatic transmission support structure can solve the above problems well. Utility Model Content

[0007] The purpose of the present utility model is to provide an AT automatic transmission support structure to solve the problem proposed in the above-mentioned background technology that the transmission is supported only by a bracket assembly, resulting in poor support effect on the transmission, making it easy for the transmission to produce large-scale non-directional jumps under harsh working conditions, causing the flywheel housing and clutch housing connected to the transmission to bear large torque, thereby affecting the normal service life of the transmission.

[0008] To achieve the above objectives, the present invention provides the following technical solutions: an AT automatic transmission support structure, comprising a fixing bracket, a transmission body is provided below the fixing bracket, a first connecting seat is welded to the top of the transmission body, and second connecting seats are welded to the left and right sides of the top of the transmission body, and threaded holes are provided on the tops of the two second connecting seats and the interior of the first connecting seat;

[0009] A docking plate is fixedly connected to the middle position of the bottom of the fixing bracket, and mounting plates are fixed to the left and right sides of the top of the fixing bracket, and the front of the mounting plate is integrally formed with reinforcing ribs;

[0010] A worm is connected to the inside of the fixed bracket, and a worm wheel is connected to the fixed bracket below the two ends of the worm through an axis rotation. A driving gear is fixed to the shaft end of the worm wheel. Clamping plates are connected to the left and right sides of the bottom of the fixed bracket, and a driven gear is fixed to the shaft end of the clamping plate.

[0011] Preferably, the mounting plate is arranged in an "L" shape, and threaded holes are provided at equal intervals inside both ends of the mounting plate.

[0012] Preferably, the worm is connected to the fixed bracket via a bearing, one end of the worm extends out of the right side of the fixed bracket, and the worm is meshed with the two worm wheels.

[0013] Preferably, the worm gear and the driving gear share a shaft, the two clamping plates and the fixed bracket are hingedly connected, and the driving gear and the driven gear are meshedly connected.

[0014] Preferably, the two clamping plates are both arranged in an arc shape, and the opposite surfaces of the two clamping plates are both provided with sound-absorbing cotton.

[0015] Preferably, a support seat is welded symmetrically on the bottom of the fixed bracket about the center point of the docking plate, and a sleeve is provided inside the support seat, a fixing screw is connected through the inside of the sleeve, and a driving gear is fixed on the outside of the sleeve, and a rack is connected through the inside of the support seat.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: the AT automatic transmission support structure adopts a new structural design, the specific contents of which are as follows:

[0018] (1) Rotate the worm to rotate the two worm wheels. Since the worm wheel and the driving gear share a shaft, the driven gear rotates and drives the clamping plate to rotate. At this time, the two clamping plates rotate relative to each other, which can clamp and fix the gearbox body, thereby preventing the gearbox body from non-directional jumping, ensuring the stability of the installation, and protecting the gearbox body.

[0019] Furthermore, the docking plate on the fixing bracket is connected to the first connecting seat on the gearbox body and fixed together with bolts, so that the gearbox body can be stably fixed on the fixing bracket;

[0020] Furthermore, by arranging sound-absorbing cotton on the side of the clamping plate, the energy of the sound waves can be effectively reduced, thereby reducing the noise generated when the gearbox body is working.

[0021] (2) The fixing bracket is fixed to the vehicle frame through a mounting plate and multiple bolts, thereby reducing the torque borne by the gearbox body during operation, effectively extending the service life of the gearbox body, and utilizing the provided reinforcing ribs to enhance the overall strength of the mounting plate, preventing the mounting plate from deforming when subjected to force, thereby extending the service life of the device.

[0022] (3) When the two clamping plates rotate relative to each other, they can push the rack to move and drive the meshing drive gear to rotate, causing the sleeve to rotate. At this time, the fixing screw connected to the inner thread of the sleeve moves downward and screws into the threaded hole on the second connecting seat, which can fix the gearbox body and further improve the support effect of the gearbox body.

[0032] See also Figure 1-Figure 7 , the utility model provides the following technical solutions: an AT automatic transmission support structure;

[0033] Embodiment 1: In order to solve the problem that the existing technology relies solely on the bracket assembly to support the gearbox, resulting in poor support effect for the gearbox, making the gearbox prone to large-scale non-directional jump under harsh working conditions, causing the flywheel housing and clutch housing connected to the gearbox to bear large torque, thereby affecting the normal service life of the gearbox, the following solution is disclosed, specifically referring to Figures 1-4 and Figure 7 As shown, it includes a fixing bracket 1, a gearbox body 2 is arranged below the fixing bracket 1, and a first connecting seat 3 is welded to the top of the gearbox body 2, and second connecting seats 4 are welded on the left and right sides of the top of the gearbox body 2, and threaded holes are provided on the tops of the two second connecting seats 4 and the insides of the first connecting seat 3.

[0034] A docking plate 5 is fixedly connected to the middle position of the bottom of the fixed bracket 1, and a mounting plate 6 is fixed on the left and right sides of the top of the fixed bracket 1. The mounting plate 6 is set in an "L" shape, and threaded holes are opened at equal intervals inside the two ends of the mounting plate 6, and a reinforcing rib 7 is integrally formed on the front of the mounting plate 6; a worm 11 is connected to the inside of the fixed bracket 1, and a worm wheel 17 is connected to the inside of the fixed bracket 1 below the two ends of the worm 11 through an axis rotation, and a driving gear 18 is fixed to the shaft end of the worm wheel 17. The worm 11 and the fixed bracket 1 are connected by a bearing, and one end of the worm 11 extends out of the right side of the fixed bracket 1, and the worm 11 and the two worm wheels 17 are meshed. The left and right sides of the bottom of the fixed bracket 1 are connected with a clamping plate 8, and the shaft end of the clamping plate 8 is fixed with a driven gear 10. The worm wheel 17 and the driving gear 18 share a shaft rod, and the two clamping plates 8 are hingedly connected to the fixed bracket 1, and the driving gear 18 and the driven gear 10 are meshed.

[0035] First, the fixing bracket 1 is fixed to the vehicle frame through the mounting plate 6 and multiple bolts, thereby reducing the torque borne by the gearbox body 2 during operation, effectively extending the service life of the gearbox body 2, and using the provided reinforcing ribs 7 to enhance the overall strength of the mounting plate 6, preventing the mounting plate 6 from deforming when subjected to force, thereby extending the service life of the device, and then the docking plate 5 on the fixing bracket 1 is connected to the first connecting seat 3 on the gearbox body 2, and fixed together by bolts, so that the gearbox body 2 can be stably fixed on the fixing bracket 1, and then the worm 11 is manually rotated to make the two worm gears 17 rotate, and because the worm gear 17 and the driving gear 18 share a shaft, the driven gear 10 rotates and drives the clamping plate 8 to rotate.

[0039] When the two clamping plates 8 rotate relative to each other, they can push the rack 12 to move, and drive the meshing drive gear 13 to rotate, so that the sleeve 14 rotates. At this time, the fixing screw 15 threadedly connected to the inside of the sleeve 14 moves downward and screws into the threaded hole on the second connecting seat 4, which can fix the gearbox body 2 and further improve the support effect of the gearbox body 2.
