Embodiment Construction
[0012] The motor suspension of the cast aluminum frame includes two identical and symmetrical wide reinforcing ribs 2 located in the middle of the left and right sides of the frame 1, which are integrally casted with the frame 1, respectively located under the two wide reinforcing ribs 2 and The base 1 is connected with two horizontal plates 3 with the same structure, and the cross section of the wide reinforcing rib 2 is an irregular triangle. Located in the same plane as the upper end surface of the wide reinforcing rib 2, the horizontal plate 3 is integrally casted with the machine base 1 and the wide reinforcing rib 2, and the two ends of the horizontal plate 3 located outside the wide reinforcing rib 2 are respectively provided with mounting holes 4 .
[0013] Further, the vertex of the angle between the outer hypotenuse and the lower base of the triangle of the wide reinforcing rib 2 is located in the same plane as the outer surface of the transverse plate 3 . Such a st...

The invention relates to a motor seat part, in particular to a cast aluminum machine base motor hanger. The cast aluminum machine base motor hanger comprises two wide reinforcing ribs and two cross plates, wherein structures of the wide reinforcing ribs are exactly the same, the wide reinforcing ribs are symmetrically located in the middle of the left side of the machine base and the in the middle of the right side of the machine base, the two cross plates are located below the two wide reinforcing ribs respectively to be connected with the machine base, and structures of the cross plates are completely the same, the cross sections of the wide reinforcing ribs are scalene triangles, the bevel edges of the triangles are arc edges matched with the outer side face of the machine base, the lower edges of the triangles and the upper end faces of the wide reinforcing ribs are located in the same plane, the cross plates are integrally formed with the wide reinforcing ribs in a casting mode, and the two ends of cross plates on the outer sides of the wide reinforcing ribs are respectively provided with an installation hole. The cast aluminum machine base motor hanger has the following advantages of solving the problem that the cast aluminum machine base motor hanger is prone to failure under impact vibration and self-gravity of the motor when the machine base and the hanger which are made of a cast aluminum material are used by an electric car motor.
Description
technical field [0001] The invention relates to a motor frame component, in particular to a cast aluminum frame motor hanger. Background technique [0002] Electric vehicle is a new energy green vehicle that has emerged in recent years. It uses electric energy as the power source and drives the vehicle through a power traction system composed of a controller and a traction motor. Compared with traditional fuel vehicles, it has the advantages of zero emission, no pollution, energy saving, consumption reduction, and environmental protection. The core of electric vehicles is the power drive system, including controllers and traction motors. Due to the space constraints of electric vehicles and the requirements for fast running and energy saving, the on-board equipment should be as small as possible and light in weight. In order to reduce the weight of the vehicle-mounted traction motor, the motor frame is made of cast aluminum instead of steel plate. The use of cast aluminum ...
