Problems solved by technology
At present, the independent main reducers in the domestic market are mainly products of foreign automobile companies or joint ventures. The market for domestic products is small and the technology lags behind.
Moreover, the NVH bench test device for the independent main reduction of automobiles is rare in China at present, and the fixed installation device for the bench test is specific, and there is no serialization and modularization of tooling, but the NVH performance test of the independent main reduction is important One of the performance tests

Embodiment Construction
[0025] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0026] It should be noted that if there are directional indicating terms in the present invention, such as up, down, left, right, front, back direction and orientation terms, they are for the convenience of describing the relative positional relationship between components, not for related components and positions between components The absolute position of the relationship is specified, and it is only used to explain the relative positional relationship, movement conditions, etc. between the components in a specific posture. If the specific posture changes, the directional indication will also change accordingly. If there are terms related to quantity in the present invention, such as "many", "multiple", "several", etc., it specifically refers to two or more.
[0027] Such as Figure 1 to Figure 6 As shown in , the independent main reduction ...

The invention discloses an independent main damping NVH bench test fixing tool, belongs to the technical field of automobile manufacturing, and provides an independent main damping NVH bench test fixing tool with good universality. The tool comprises a base plate, a front support welding assembly and two rear support welding assemblies, and the two welding assemblies are respectively a right rear support welding assembly and a left rear support welding assembly. The base plate, the front support welding assembly and the rear support welding assemblies are arranged, and meanwhile the front support welding assembly and the rear support welding assemblies are installed in the mode that vertically-distributed kidney-shaped holes are matched, so that the positions of the front support welding assembly and the rear support welding assemblies on the base plate can be adjusted at will; and the left-right symmetrical or asymmetric position fixation of the independent main damping can be realized, so that the test installation requirements of independent main dampings with different models and sizes can be met, and the universality of the tool can be effectively improved.
Description
technical field [0001] The invention relates to the technical field of automobile manufacturing, in particular to a fixed tool for an independent main reduction NVH bench test. Background technique [0002] As one of the core components of the automobile transmission system, the main reducer has an important impact on the vehicle's NVH (Noise, Vibration, Harshness) technology and key performances such as vehicle comfort, quality, and cost. It is an integrated Multidisciplinary research fields such as gear design and manufacturing, friction lubrication, dynamic simulation, and materials are also one of the core research fields of the global automotive industry. The excellent NVH performance development of the final drive can improve vehicle comfort, improve reliability, realize lightweight, and reduce the cost of the whole life cycle. [0003] There are two types of driving methods for automobiles: front drive and rear drive. The rear drive usually adopts the integrated stru...
