Description

Technical Field

[0001] This utility model relates to the field of detection device technology, specifically to an automotive transmission output detection device. Background Technology

[0002] An automotive transmission output testing device is a device used to test the performance and operating status of an automotive transmission. It evaluates the transmission efficiency, shift quality, and reliability of the transmission by measuring the transmission's input and output parameters, such as speed, torque, temperature, and shift performance. This device is commonly used for quality inspection on the production line, fault diagnosis in repair shops, and performance optimization during the research and development process. It can simulate actual driving conditions to perform life tests, performance tests, and fault analysis on the transmission.

[0003] The existing automotive transmission output test device sets up three independent drive mechanisms for high, medium and low speeds. Each drive mechanism includes a motor, a gearbox, a clutch and gears. The gears of one drive mechanism are mounted on a rotating main shaft, while the gears of the other two drive mechanisms mesh with the gears on the rotating main shaft. By adjusting the motor frequency, the number of gear shifts in the gearbox or the number of gear shifts, different speeds can be achieved. The power transmission is controlled by the engagement and disengagement of the clutch, thereby realizing performance testing at high, medium and low speeds, and the speeds can be smoothly switched and seamlessly connected.

[0004] Although existing automotive transmission output testing devices can meet the performance testing requirements at high, medium, and low speeds and have certain functional advantages, their design has some obvious limitations in practical applications, especially in terms of energy consumption and cost. First, the device requires multiple independent drive mechanisms, each equipped with a motor. This means that the entire device needs multiple motors to achieve the driving function of different speed modes. While this multi-motor design can achieve diverse speed outputs, it also brings high energy consumption. In actual operation, even if only one drive mechanism is working, the other motors need to remain in standby mode to switch to the corresponding speed mode at any time. Although this standby mode seems to consume little energy, it actually consumes a certain amount of electricity continuously, leading to an increase in overall energy consumption. Especially during long-term testing, this additional energy consumption can accumulate to a considerable amount, not only increasing testing costs but also posing a challenge to the efficient use of energy. Therefore, an automotive transmission output testing device is proposed to address the above problems. Utility Model Content

[0005] The purpose of this invention is to provide an automotive transmission output detection device to solve the problems of energy consumption, cost, and maintenance frequency caused by using multiple motors to achieve different speed modes.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An automotive transmission output testing device includes a worktable and a stepper motor. A first output component, a second output component, and a third output component are rotatably connected to the upper end of the worktable. An output shaft is fixedly connected to the right end of the first output component. The third output component includes a gear. A shaft is fixedly connected to the right side of the gear.

A second disc is fixedly connected to the left side of the right end of the shaft. A toothed pulley is fixedly connected to the right side of the right end of the shaft.

[0008] As a further optimization of this utility model, the first output component, the second output component, and the third output component have the same structure, and are all connected by gear meshing. The first output component, the second output component, and the third output component are all rotatably connected by a toothed pulley and a toothed belt.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] In this invention, by setting a first output component, a second output component, and a third output component, the device achieves precise control of three different speeds: high, medium, and low. It does not rely on multiple independent drive motors. This design significantly reduces the energy consumption of the device and reduces the additional power consumption caused by the standby state of multiple motors. Especially during long-term testing, the energy-saving effect is obvious, effectively reducing the testing cost. At the same time, it reduces the use of motors and related components, lowers the manufacturing cost and maintenance frequency of the device, and improves the practicality and economy of the device.

[0028] Please see Figure 1-6 This utility model provides a technical solution:

[0029] The automotive transmission output testing device includes a workbench 1 and a stepper motor 2. The upper end of the workbench 1 is rotatably connected to a first output component 3, a second output component 4, and a third output component 5. The right end of the first output component 3 is fixedly connected to an output shaft 6. The third output component 5 includes a gear 51. The right side of the gear 51 is fixedly connected to a shaft column 52. The right side of the shaft column 52 is fixedly connected to a first disc 53. A connector rod 54 is inserted into the inside of the first disc 53. The right side of the connector rod 54 is fixedly connected to a sleeve 57. A bolt 58 is screwed into the inside of the sleeve 57. The connector rod 54 slides inside the second disc 55. The left side of the right end shaft column 52 is fixedly connected to the second disc 55. The right side of the right end shaft column 52 is fixedly connected to a toothed belt pulley 56.

[0030] As a further implementation of this solution, the first output component 3, the second output component 4, and the third output component 5 have the same structure. The first output component 3, the second output component 4, and the third output component 5 are all meshed with each other by gear 51, and the first output component 3, the second output component 4, and the third output component 5 are all rotatably connected by toothed pulley 56 and toothed belt. Through the above settings, the uniformity and stability of power transmission are ensured, the design and manufacturing process is simplified, the production cost is reduced, and maintenance and replacement are convenient.

[0031] As a further implementation of this solution, the left side of the first output component 3 is fixedly connected to the end of the main shaft of the stepper motor 2. The center of the main shaft of the stepper motor 2, the center of the first output component 3, and the center of the output shaft 6 are on the same horizontal line. The worktable 1 includes a base plate 11, and a vertical plate 12 is fixedly connected to the top of the base plate 11. A bearing mounting hole 13 is opened on the inner side of the vertical plate 12, and a ball bearing 14 is fixedly connected to the inner side of the bearing mounting hole 13. Through the above settings, the linearity and coaxiality of the power transmission are ensured, mechanical vibration and wear are reduced, the transmission efficiency and the operation stability of the device are improved, stable support and precise positioning are provided for the device, the overall structural strength and stability of the device are enhanced, and the coordinated work of each component is ensured.

[0032] As a further implementation of this solution, the outer sides of the first output component 3, the second output component 4, the third output component 5 and the output shaft 6 are all fixedly connected to the ball bearing 14, and the outer sides of the first output component 3, the second output component 4, the third output component 5 and the output shaft 6 are all embedded in the interior of the vertical plate 12. Through the above arrangement, the friction and wear between the components are reduced, and the durability and service life of the device are improved.

[0033] As a further implementation of this solution, an external connector 15 is fixedly connected to the top of the base plate 11, an external slot 16 is provided on the inner side of the external connector 15, an electromagnet 17 is fixedly connected to the inner side of the external slot 16, and the outer side of the output shaft 6 is fixedly connected to one side of the permanent magnet 18. With the above settings, the rotating output shaft 6 can be stopped quickly, thereby improving the safety of the detection.

[0034] As a further implementation of this solution, the first disc 53 has an insertion hole on its inner side, the second disc 55 has a sliding hole on its inner side, the right end shaft 52 has a threaded hole on its inner side, and the sleeve 57 is fitted onto the outside of the right end shaft 52. Through the above arrangement, the first output component 3, the second output component 4 and the third output component 5 are engaged and disengaged, improving the convenience of maintenance and reducing the cost of use.

[0035] Workflow: When testing the automotive transmission, first fix the output shaft 6 to the transmission power output end. To achieve the highest speed test, remove the bolt 58 on the third output assembly 5 from the right-end post 52. Push the sleeve 57 to the left, causing the sleeve 57 to move the insertion rod 54 to the left, inserting it into the insertion hole inside the first disc 53. At this time, the insertion rod 54 slides inside the sliding hole of the second disc 55. Then fix the bolt 58 to the screw hole on the left end, thus fixing the sleeve 57 to the right-end post 52. The insertion rod 54 on the first output assembly 3 and the second output assembly 4 moves away from the sliding hole of the first disc 53. At this time, start the stepper motor 2 to drive the left side of the first output assembly 3 to rotate. Since the left and right parts of the first output component 3 and the left and right parts of the second output component 4 are separated, when the first output component 3 rotates, it will drive the left part of the second output component 4 to rotate, and at the same time, it will also drive the gear 51 and the left end shaft 52 to rotate. Through the design of multiple vertical plates 12 and ball bearings 14, the stability of the first output component 3, the second output component 4 and the third output component 5 during rotation can be improved, and the frictional force during rotation can be reduced. When the gear 51, shaft 52 and the first disc 53 of the third output component 5 rotate, the right end shaft 52 and the toothed pulley 5 will be driven through the plug rod 54, sleeve 57 and bolt 58. 6. Simultaneously rotating, the diameter of gear 51 in the third output component 5 is 0.5 times the diameter of gear 51 in the first output component 3, and the diameter of gear 51 in the second output component 4 is 0.75 times the diameter of gear 51 in the first output component 3. However, the toothed pulleys 56 at the right ends of the first output component 3, second output component 4, and third output component 5 all have the same diameter, and the toothed pulleys 56 between them are connected by toothed belts. Therefore, when the first output component 3 rotates, with the main shaft rotation speed of the stepper motor 2 remaining constant, the rotation speed of the third output component 5 is the fastest, the second output component 4 is in the middle, and the first output component 3 is the slowest. This ensures smooth operation. The toothed pulley 56 drives the right side of the first output component 3 to rotate. The right side of the first output component 3 rotates at a relatively fast speed. When it is necessary to adjust the rotation speed of the output shaft 6, the electromagnet 17 is activated to magnetically attract the permanent magnet 18, thereby increasing the resistance when the output shaft 6 rotates, causing the output shaft 6 to stop quickly. After stopping, following the same principle, one of the designated first output component 3, second output component 4, or third output component 5 is connected while the others are disconnected. Then, the corresponding tests are performed. Based on the above principles, when the device achieves high, medium, and low speed control, it does not need to use multiple drive motors, which reduces the energy consumption, cost, and maintenance frequency of the device, improves the practicality of the device, and enhances its market competitiveness.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
