Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of drive axle detection, in particular to a multi-angle test device for a drive axle. Background Art
[0002] The drive axle is an axle-shaped component that is equipped with wheels to support the weight of the car, and is equipped with a main reducer and a differential to drive the wheels forward. The drive axle is generally composed of a main reducer, a differential, a half shaft, a drive axle housing, etc. Among them, the main reducer is used to change the transmission direction, reduce the speed, and increase the torque; the differential is used to achieve the differential effect of the wheels on both sides; the half shaft transmits the torque from the differential to the drive wheel; the drive axle housing plays the role of supporting and protecting other components. It can be seen that the drive axle is a crucial component in the automobile transmission system, and its performance and structure directly affect the power, economy, comfort and safety of the car.
[0003] At present, after the drive axle is assembled, in order to ensure its normal operation, the staff needs to test the assembly before it goes offline. The test run of a drive axle assembly, including a series of actions such as filling lubricating oil, idling, no-load, braking, loading, and draining, takes an average of more than 40 minutes, which creates huge pressure on the production cycle. Therefore, the offline inspection of the drive axle assembly is carried out at a ratio of 10-20%. For the drive axle assembly that is not on the test bench, manual rotation is used to ensure that the drive axle assembly has no abnormal problems such as jamming and abnormal noise. This process requires 100% implementation.
[0004] Although manual testing can detect the operation of the drive axle assembly, there are still the following shortcomings in the actual operation process: the rotation resistance torque of the single-stage axle of an ordinary heavy truck is 5-20N.M, and the rotation resistance torque of the double-stage drive axle of an ordinary heavy truck is even 30-50N.M. In particular, the rotation resistance torque of the double-stage drive axle equipped with a cassette oil seal hub is as high as 70-90N.M. The drive axle cannot be rotated without external force, which is easy to cause misjudgment and repair, which is time-consuming and labor-intensive. At the same time, the existing test benches cannot achieve reverse testing by rotating the hub assembly. At present, reverse testing is completely achieved by manually rotating the hub.

[0024] Please refer to the attached Figure 1In combination with a specific embodiment, the following is described: A multi-angle test device for a drive axle described in the utility model includes a supporting main beam 1 and a supporting plate 3, the top of the supporting main beam 1 is hinged with a motor support 2, the bottom end of the supporting main beam 1 is hinged with the top side of the supporting plate 3, a telescopic rod A4 for driving the motor support 2 to rotate is arranged at the top of the supporting main beam 1, a telescopic rod B5 for driving the supporting main beam 1 to rotate is arranged at the bottom of the supporting main beam 1, and the supporting main beam 1 and the motor support 2 rotate in the same plane.
[0025] Specifically, the telescopic rod A4 and the telescopic rod B5 are arranged symmetrically, and both the telescopic rod A4 and the telescopic rod B5 can be hydraulic telescopic rods. This symmetrical arrangement is more reasonable and can avoid the problem of interference between the two telescopic rods during the telescopic process.
[0026] Specifically, a mounting groove A101 for mounting the telescopic rod A4 is provided at the top of the supporting main beam 1, and a mounting groove B102 for mounting the telescopic rod B5 is provided at the bottom of the supporting main beam 1. The design of the above mounting grooves can reduce the difficulty of mounting the telescopic rod A4 and the telescopic rod B5 and improve the mounting efficiency.
[0027] The top side of the motor support 2 is rotatably connected to the motor assembly 6, and the motor assembly 6 can rotate 360° in the top side plane of the motor support 2, and the output shaft of the motor assembly 6 is connected to the fixed disk 7; a plurality of connecting holes are opened on the fixed disk 7, and the fixed disk 7 can be connected to the transmission shaft flange 13 of the drive axle assembly 12 or to the wheel assembly 14 of the drive axle assembly 12 through the connecting through holes.
[0028] Specifically, a connecting shaft 201 is provided on the top side of the motor support 2, and the motor support 2 is rotatably connected to the motor assembly 6 via the connecting shaft 201. The connecting shaft 201 can not only provide good support, but also be more conducive to the rotation of the motor assembly 6.
[0029] The use principle of this utility model:
[0030] Referring to the existing automobile production line, during the test run, the drive axle assembly 12 is placed on the axle assembly bracket 16 and transported through the production line plate chain 15. The device is installed at the production line station corresponding to the production line plate chain 15 through the support plate 3. The test run of the drive axle assembly 12 generally includes a forward test run and a reverse test run, wherein the forward test run also includes the vertical state of the transmission shaft flange 13 and the horizontal state of the transmission shaft flange 13.
[0031] Reference Figure 2When the transmission shaft flange 13 is in a vertical state, the staff starts the telescopic rod A4 to adjust the inclination of the motor assembly 6, and starts the telescopic rod B5 to adjust the inclination of the supporting main beam 1. At the same time, by rotating the motor assembly 6, the fixed plate 7 can correspond to the transmission shaft flange 13, and then the fixed plate 7 and the transmission shaft flange 13 are connected together through fixing parts such as fixing pins, and finally the motor assembly 6 is started. At this time, the motor assembly 6 drives the transmission shaft flange 13 to rotate through the fixed plate 7, that is, drives the various gear meshing components inside the drive axle assembly 12 to rotate, so as to quickly determine whether the axle assembly has a fault.
[0032] Reference Figure 3 When the transmission shaft flange 13 is in a vertical state, similarly, the staff first adjusts the fixed plate 7 to a position corresponding to the transmission shaft flange 13, and then connects the fixed plate 7 and the transmission shaft flange 13 together through fixing pins and other fixing parts. After installation, the test run can be carried out.
[0033] Reference Figure 4 When a reverse test run is required, similarly, the staff first adjusts the fixed plate 7 to a position corresponding to the wheel assembly 14, and then connects the fixed plate 7 to the wheel assembly 14 through fixing parts such as wheel bolts. Through the above connection, it can be ensured that the power of the motor assembly 6 can be transmitted to the wheel assembly 14, thereby realizing a reverse test run.
[0034] In one of the embodiments, a slideway groove 103 is provided on the top side of the support plate 3, and the slideway groove 103 is slidably connected to the main beam support 8, and the main beam support 8 is hinged to the bottom end of the support main beam 1; one end of the telescopic rod B5 is hinged to the support main beam 1, and the other end of the telescopic rod B5 is hinged to the main beam support 8; two parallel slideway grooves are provided on the bottom side of the support plate 3, and the slideway grooves are slidably connected to the slide rails 9, and the slideway grooves 103 and the slideway grooves are perpendicular to each other. Through the design of the slideway groove 103 and the main beam support 8, the staff can move the support main beam 1 along the width direction of the support plate 3, and through the design of the slideway groove and the slide rail 9, the staff can move the support plate 3 along the length direction of the support plate 3, and the slideway groove 103 is arranged perpendicular to the slideway groove. It can be seen that the above design realizes the horizontal position adjustment and vertical position adjustment of the device in the same plane, thereby greatly improving the adaptability of the device.
