Description

Technical Field

[0001] The utility model relates to the technical field of vehicle manufacturing, in particular to a reducer centering mounting bracket. Background Art

[0002] With the mature development and increasing popularity of new energy vehicles, the whole vehicle system test issues of new energy vehicles have received more and more attention from OEMs. Before new cars are launched, they need to undergo strict performance tests and durability tests on the key core components, the reducer. In the past, the reducer test was to install the reducer on a special fixed bracket and connect it to the dynamometer for testing. Due to the differences in reducer models configured for different models, the shape, size, size, and installation method of the reducer are different, and the height of its suspension is also different. This will cause the reducer assembly and the dynamometer at both ends to be at different levels, requiring up and down, left and right adjustments, which makes alignment very difficult. Therefore, it is necessary to frequently design corresponding tooling and fixation, which not only prolongs the working cycle and reduces work efficiency, but also causes a waste of resources. Therefore, it is necessary to design a new adjustable mounting bracket that is suitable for the installation and alignment of reducers of different types and models. Utility Model Content

[0015] Figure 2 It is a top view of the fixing plate in the utility model. DETAILED DESCRIPTION

[0016] like Figure 1 The reducer centering mounting bracket shown in the figure comprises a base 1, a support tube 3 is fixedly connected to the base 1, a support rod 4 is movably connected to the support tube 3, and a fixing plate 7 is fixedly arranged on the upper end of the support rod 4; Figure 2 As shown, the fixing plate 7 is provided with a plurality of fixing holes 71 for fixing the reducer.

[0017] Preferably, in combination with the above solution, in order to be able to adjust the height more accurately, the support rod 4 is movably connected to the support tube 3 through a threaded structure. Generally, it is only necessary to set the threaded structure within the upper third of the support rod 4.

[0018] Preferably, in combination with the above solution, in order to tighten and limit after adjusting the height, a bolt hole is fixedly provided on the outer wall of the support tube 3, a fastening nut 5 is fixedly connected to the bolt hole, and a fastening bolt 6 is provided to pass through the fastening nut 5 and the bolt hole in sequence to abut against the side wall of the support rod 4. The fastening nut 5 can be provided to abut against the middle position of the support rod 4.

[0019] Preferably, in combination with the above scheme, in order to facilitate the connection and assembly with the fixing plate 4, the upper part of the support rod 4 is provided with a thread, the center of the fixing plate 7 is provided with a threaded hole 72, and the support rod 4 is fixedly connected to the fixing plate 7 by screwing.

[0020] Preferably, in combination with the above solution, in order to enhance the stability of the structure, the upper end surface of the base 1 and the outer side wall of the support tube 3 are fixedly connected by a plurality of groups of reinforcing plates 2.
