DETAILED DESCRIPTION

[0038] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0039] Reference Figure 1-Figure 7 , an embodiment provided by the present invention: a transmission system testing and adjusting device, comprising: a testing platform 1;

[0040] The test platform 1 is provided with a plurality of guide rails 11; the plurality of guide rails 11 are arranged in parallel;

[0041] A torque converter test mechanism 2 and a gearbox test mechanism 3 are provided on the plurality of guide rails 11, and the distance between the gearbox test mechanism 3 and the torque converter test mechanism 2 is adjusted;

[0042] The bottoms of the transmission test mechanism 3 and the torque converter test mechanism 2 are connected to at least two guide rails 11 .

[0043] In this embodiment, a torque converter testing mechanism 2 and a gearbox testing mechanism 3 are arranged on the test platform 1 via a guide rail 11, and the distance between the gearbox testing mechanism 3 and the torque converter testing mechanism 2 is adjusted; the torque converter testing mechanism 2 and the gearbox testing mechanism 3 are connected via a transmission shaft 4, and a driving mechanism 5 and a parameter detection mechanism 6 are provided on the torque converter testing mechanism 2, so that the action of the torque converter testing mechanism 2 is transmitted to the gearbox testing mechanism 3 for detection.

[0044] By arranging a movable torque converter test mechanism 2 and a gearbox test mechanism 3 on the test platform 1, it is possible to replace different models of torque converters 23 and gearboxes 32, and adjust the relative distance between the torque converter test mechanism 2 and the gearbox test mechanism 3 via the guide rail 11 to adapt to different testing requirements. By designing the test platform, torque converter test mechanism, and gearbox test mechanism, and using the transmission shaft for transmission, the relative position of the two can be adjusted according to the specific models of the torque converter 23 and gearbox 32, allowing the torque converter and gearbox to be tested separately or in combination. The transmission shaft 4 is a transmission component that connects the gearbox 32 and the torque converter 23 to transmit torque, and transmits the power of the drive mechanism 5 to the gearbox 32 to realize the operation of the gearbox 32.

[0045] The torque converter test mechanism 2 includes a protective cover 21 . A torque converter test bench 22 is installed on the protective cover 21 along the direction in which the guide rail 11 is arranged. A torque converter 23 is installed at the output end of the torque converter test bench 22 .

[0046] In this embodiment, the torque converter test bench 22 supports the installation of the torque converter 23 and is suitable for different flywheel installations depending on the model of the torque converter 23. Specifically, the torque converter test bench 22 offers a variety of flywheel housing mounting methods and flexible disc power transmission installation options, including bolted connections, snap-on connections, flange connections, welding, keyway connections, and clamp fixation. These options can be selected based on the model and requirements of the torque converter 23, allowing testing of multiple series of torque converters 23 without the need for additional tooling. This can meet the testing requirements of DANA C270, C3000, C5000, C8000, and C9000 series transmissions.

[0047] The driving mechanism 5 is installed inside the protective cover 21 . The driving mechanism 5 passes through the protective cover 21 and the torque converter test bench 22 and is electrically connected to the torque converter 23 .

[0048] In this embodiment, the drive mechanism 5 is the power source of the entire transmission test system, including a motor and a motor control system, which can realize remote control, including the start and stop of the motor, speed regulation, etc. The motor power is 132KW, and the speed can be steplessly adjusted from 0-3000rpm to simulate the whole vehicle electric drive or engine drive vehicle test.

[0049] The parameter detection mechanism 6 is installed outside the protective cover 21 .

[0050] In this embodiment, the parameter detection mechanism 6 includes a pressure detector, a temperature detector, and a flow detector, which can meet the requirements for detecting parameters such as the torque converter 23 outlet flow, pump flow, transmission 32 flow, and lockout flow. The pressure detector can meet the requirements for detecting parameters such as the transmission 32 main oil pressure, the torque converter 23 safety pressure, the pressure of each gear, and the lockout pressure. The temperature detector can detect the temperature of the transmission oil.

[0051] The gearbox testing mechanism 3 includes a gearbox testing bench 31 , which reciprocates along the setting direction of the guide rail 11 to perform position adjustment.

[0052] A gearbox 32 is provided on the upper end surface of the gearbox test bench 31 to support the gearbox 32. The bottom of the gearbox test bench 31 cooperates with the guide rail 11 of the test platform 1 and is positioned by clamping tooling such as bolts. It can also be moved along the guide rail 11 of the test platform 1 to facilitate combined testing of various transmission systems. A connecting frame can also be provided on the gearbox test bench 31 for quick adaptation and installation of the gearbox 32. According to different gearbox designs, it is fixed to the gearbox test bench 31 by bolts; the connecting frame is also bolted to the gearbox 32.

[0053] A hydraulic pump station 7 is also installed on the inner side of the protective cover 21 and is connected to the torque converter 23 and the gearbox 32 through pipelines via a transmission oil radiator 8 and a transmission oil filter 9.

[0054] In this embodiment, the hydraulic pump station 7 is the hydraulic power source of the transmission system. When the gearbox 32 is tested alone, it can provide a pressure source for the clutch to ensure normal lubrication and shifting of the clutch. The transmission oil radiator 8 dissipates heat for the entire transmission system to prevent high temperatures from affecting the test conclusions during transmission system testing. The transmission oil filter 9 is a guarantee of the cleanliness of the oil in the entire transmission system. It is a fine filter to prevent transmission system oil contamination.

[0055] The end surface of the test platform 1 is provided with a plurality of T-shaped grooves to form a plurality of guide rails 11 , and the end surface of the test platform 1 is provided with at least one oil drain port 12 .

[0056] In this embodiment, the material of the test platform 1 is cast iron, and a number of T-shaped slots are integrated on the upper surface to form a number of guide rails 11, which can facilitate the movement of the torque converter test mechanism 2 and the gearbox test mechanism 3. Due to the diversity of the gearbox 32 and the torque converter 23, the gearbox test bench 31 will inevitably move along with the guide rail 11 according to the test requirements. The end face of the test platform 1 is provided with at least one oil drain port 12. In this application, four oil drain ports are preferably provided, which are arranged on one side or four corners of the test platform 1, and a plug is provided on the outside. If there is oil leakage from the test piece or the pipeline during the test, the oil can be drained through the oil drain hole on the T-shaped platform.

[0057] Reference Figure 8 The present invention further provides an embodiment of a transmission system test circuit, which is applicable to the test device of any one of the above technical solutions, including:

[0058] Hydraulic pump station 7;

[0059] The output end of the hydraulic pump station 7 is connected to the transmission oil filter 9 through the double gear pump 701. The output end of the transmission oil filter 9 is connected to the solenoid valve 702 and the pressure test gauge. The output end of the pressure test gauge is connected to the pressure regulating valve 703. The output end of the pressure regulating valve 703 is directly connected to the hydraulic pump station 7 or connected to the hydraulic pump station 7 through the pressure reducing valve 704.

[0060] The output end of the pressure regulating valve 703 is also connected to the device under test. One end of the device under test is connected to the hydraulic pump station 7 through the double gear pump 701, and the other end is connected to the cooler 705 through several temperature detectors and pressure detectors. The output end of the cooler 705 is connected to the hydraulic pump station 7;

[0061] A transmission oil heater 706 is provided inside the hydraulic pump station 7 .

[0062] The device to be tested is the torque converter 23 or the gearbox 32 .

[0063] In this embodiment, the gearbox 32 and the torque converter 23 draw oil from the oil tank of the hydraulic pump station 7 and supply oil to the device under test through the pressure regulating valve 703; the pipeline connected to the device under test is connected to the test bench via a quick-change joint, which is convenient for the test personnel to operate and does not require the replacement of internal test pipelines; because the temperature of the transmission oil has a significant impact on the performance of the transmission system, a transmission oil heater 706 is integrated inside the oil tank of the hydraulic pump station 7 to quickly increase the transmission oil temperature and reduce the test waiting time; the cooler 705 has a pressure detector and a temperature detector at the oil inlet and outlet, which can timely monitor the temperature rise and pressure changes of the transmission system, thereby determining whether the transmission system meets the requirements.

[0064] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
