Description

Technical Field

[0001] This utility model relates to the field of gearbox technology, and in particular to a reinforced gearbox housing. Background Technology

[0002] A reinforced gearbox housing refers to a housing that, based on a traditional gearbox housing, has been optimized in structure, upgraded in materials, or improved in manufacturing processes to achieve superior performance in terms of strength, rigidity, lightweight, heat dissipation, and NVH performance (noise, vibration, and acoustic roughness).

[0003] A Chinese patent (publication number: CN222823693U) discloses a reinforced gearbox housing. This patent, by setting up a reinforced support mechanism, can drive the threaded rod to rotate by rotating the screwing block. While the threaded rod rotates, its external thread will squeeze the internal thread of the threaded hole, causing the support block and U-shaped block to move upward. The U-shaped block will drive the roller to move upward, so that the surface of the roller contacts the surface of the output shaft, thereby achieving the effect of reinforced support. At the same time, the roller can rotate around the shaft without affecting the normal rotation of the output shaft. However, in practical applications, the above-mentioned patents rely entirely on feel to adjust the tightness of the contact between the roller and the output shaft. Excessive support may increase resistance, while insufficient support may result in inadequate support. There are no quantitative indicators, and operators cannot know remotely or directly whether the support mechanism is working or has failed. Once adjusted, it remains in a fixed state and cannot adapt to the dynamic requirements of the vehicle for support stiffness under different loads and vibration conditions. Utility Model Content

[0022] 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.

[0023] like Figures 1 to 3 As shown, the present invention provides the following technical solution: a reinforced gearbox housing, including a gearbox body 1, an output shaft 11 mounted on the gearbox body 1, and further comprising: The adjustable clamping support assembly 2 includes a fixed head 26 fixedly connected to the gearbox body 1. A threaded rod 25 is threadedly connected to the fixed head 26. A bearing 24 is mounted on the threaded rod 25. A support block 22 is connected to the outer wall of the bearing 24. A sliding frame 23 is slidably connected to the bottom of the support block 22. A component mounting frame 3 is connected to one side of the support block 22 via a round rod 214. An inner sliding rod 215 is slidably connected inside the component mounting frame 3. An adjusting frame 29 is connected to the component mounting frame 3 via an adjusting rod 211. A clamping rod 212 is fixedly connected to the adjusting rod 211. A sensor mounting frame 210 is movably connected to the clamping rod 212. A roller 27 is connected to the sensor mounting frame 210. The roller 27 is movably connected to the output shaft 11.

[0024] like Figures 1 to 5 As shown, in use, the operator first manually adjusts the threaded rod 25 according to the actual length of the output shaft 11. By screwing, the threaded rod 25 rotates within the fixed head 26, thereby moving the bearing 24 and support block 22 to a suitable position. The sliding frame 23 is then fixed to the mounting plate 12 with bolts, completing the initial positioning. Subsequently, the electric telescopic rod 31 is activated, which pushes the inner slide rod 215 to slide down within the component mounting frame 3. The inner slide rod 215 drives the adjusting frames 29 on both sides to move synchronously through the rotating shaft 213. The adjusting frames 29 slide along the inclined holes on the adjusting rod 211, causing the end away from the component mounting frame 3 to retract inward, driving the roller 27 to gradually clamp the output shaft 11. As the clamping resistance increases... The adjustment frame 29 presses against the adjustment rod 211, which in turn transmits the force to the sensor through the clamping rod 212. When the sensor detects that the clamping force has reached the preset optimal value, it immediately sends a signal to the controller. The controller then instructs the electric telescopic rod 31 to stop moving. The entire transmission and feedback process realizes real-time monitoring and automatic control of the support force, ensuring that the support force is always within the optimal range, preventing shaft shaking caused by insufficient support, and avoiding frictional wear caused by excessive tightness. The entire process does not require repeated manual adjustments, reducing the operating threshold and improving the reliability, safety and service life of the gearbox transmission system. It effectively solves the problem in the background technology that the manual adjustment of the prior art relies on feel and lacks quantitative indicators.

[0025] like Figures 3 to 5 As shown, the end of the adjusting frame 29 away from the roller 27 is hinged to the top of the inner slide rod 215 via a rotating shaft 213. An opening is provided on the side of the adjusting frame 29 away from the rotating shaft 213. A rotating rod 28 is movably connected to the opening on the adjusting frame 29. The rotating rod 28 is fixedly connected to the roller 27. The opening on the adjusting frame 29 allows the rotating rod 28 to slide within the opening. The rotating rod 28 is fixed to the roller 27. The opening on the adjusting frame 29 is coated with lubricating oil so that the rotating rod 28 can rotate smoothly within it.

[0026] like Figures 2 to 3 As shown, an electric telescopic rod 31 is connected to the bottom of the inner slide rod 215. A mounting plate 12 is fixedly connected to the side of the electric telescopic rod 31 away from the component mounting frame 3. The mounting plate 12 is fixedly connected to the bottom of the gearbox body 1. In use, the component mounting frame 3 integrates a sensor and a controller. The electric telescopic rod 31 is installed at the bottom of the controller. The electric telescopic rod 31 drives the inner slide rod 215 to move as a whole, causing the adjustment frames 29 located on both sides of the output shaft 11 to move inward and clamp. The sensor mounting frame 210 is fixed to the component mounting frame 3 with screws. The internal pressure transmission... The sensor (model: XJC-S07-Q-15-S, S-type load cell) has its sensing surface in contact with the clamping rod 212 to detect the pressure signal transmitted by the clamping rod. The sensor wiring harness is led out through a waterproof connector and fixed in the wire groove of the component mounting frame 3. The controller (model: STM32F103 series microcontroller) can be fixedly installed on the bracket inside the component mounting frame 3. The controller receives the sensor signal through the wiring harness and controls the movement of the electric telescopic rod 31. The controller can be equipped with a heat sink as needed, and a sealing ring is set at the mounting interface to prevent dust and oil.

[0027] like Figures 1 to 5 As shown, the sliding frame 23 is connected to the mounting plate 12. In use, the sliding frame 23 is fixed to the mounting plate 12 with bolts. After the sliding frame 23 is slid to a suitable position within the mounting plate 12 with bolts, the sliding frame 23 is fixed to the mounting plate 12 with bolts. like Figures 1 to 5 As shown, the sensor mounting frame 210 is fixedly connected inside the component mounting frame 3. In use, by fixing the sensor mounting frame 210 inside the component mounting frame 3, when the clamping rod 212 is pressed by the adjusting rod 211, it can press the sensor inside the component mounting frame 3. The adjusting frame 29 is provided with an opening for the clamping rod 212 to pass through. The clamping rod 212 slides through the opening on the side wall of the sensor mounting frame 210. When the adjusting frame 29 presses the adjusting rod 211, the adjusting rod 211 will squeeze the clamping rod 212 inward along the guiding opening, so that its end is pressed and fixed to the sensing surface of the pressure sensor inside the sensor mounting frame 210, thereby converting the clamping force into an electrical signal.

[0028] like Figure 1 As shown, the adjustment frame 29 has an opening, and the adjustment rod 211 is slidably connected in the opening on the adjustment frame 29. By setting the adjustment frame 29 to have an opening, the adjustment rod 211 slides in it during use, and the adjustment frame 29 is pressed against the top edge of the component mounting frame 3 and closes inward, driving the roller 27 to press the output shaft 11.

[0029] Working principle: like Figure 1-5 As shown, during use, the operator manually adjusts the position of the threaded rod 25 according to the actual length of the output shaft 11. The operator only needs to turn the threaded rod 25 so that the threaded rod 25 rotates in the fixed head 26 connected to it and moves away from or closer to the gearbox body 1 to adjust the position of the bearing 24. The support block 22 slides accordingly. When the support block 22 slides to the appropriate position, the sliding frame 23 is fixed to the mounting plate 12 with bolts. Then, the electric telescopic rod 31 is activated, causing the inner slide rod 215 to slide down within the component mounting frame 3. At this time, the inner slide rod 215 drives the rotating shaft 213 to slide down, causing the rotating shaft 213 to drive the adjustment frames 29 on both sides to slide down, causing the adjustment frames 29 to slide on the adjustment rod 211. The adjustment rod 211 slides through the oblique hole on the adjustment frame 29. The end of the adjustment frame 29 away from the component mounting frame 3 drives the inner clamp of the roller 27, causing the roller 27 to clamp the output shaft 11. At this time, the resistance generated by the inner clamp of the roller 27 gradually increases, causing the adjustment frame 29 to press against the adjustment rod 211. The adjustment rod 211 will squeeze the clamping rod 212, causing the clamping rod 212 to apply force to the sensor inside the adjustment frame 29. When the force reaches an appropriate level, the sensor sends a signal to the controller installed in the component mounting frame 3, causing the controller to control the electric telescopic rod 31 to stop moving.

[0030] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
