Embodiment Construction

[0033]In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be understood that the specific embodiments described here are only used to explain the present invention, and do not limit the protection scope of the present invention.

[0034] It should be noted that when an element is referred to as being “disposed on” or “fixed on” another element, it may be directly on another element or there may be an intervening element. When an element is referred to as being "fixed on" another element, or "fixedly connected" to another element, it may be detachably fixed or non-detachably fixed therebetween. When an element is referred to as being "connected" or "rotatably connected" to another element, it can be directly connected to the other element or intervening elements may also be prese...

Abstract

The invention discloses a test system, test bench, test tray and suspension device of an electric drive assembly. The suspension device comprises a first fixing part, a first suspension part and a second suspension part, wherein the first fixing part is used for fixing a motor, and the outline of the first fixing part is matched with the outline of a suspension part of the motor; the first suspension part and a first suspension structure are arranged on the same side, the first suspension part is provided with a second fixing part used for fixing one side of a reduction gearbox, and the outline of the second fixing part is matched with the outline of a suspension part on one side of the reduction gearbox; the second suspension part is provided with a first positioning part used for assisting in positioning of the other side of the reduction gearbox and a third fixing part used for fixing the other side of the reduction gearbox, and the outline of the third fixing part is matched with the outline of the other side of the reduction gearbox. The test system, test bench, test tray and suspension device of the electric drive assembly can stably and accurately fix the electric drive assembly, accurately simulate a vehicle loading posture and ensure the reliability of a test.

Description

technical field [0001] The invention relates to the technical field of testing devices, in particular to a testing system, a testing platform, a testing tray and a suspension device of an electric drive assembly. Background technique [0002] After assembling the motor, gearbox and controller into an electric drive assembly, it is necessary to conduct corresponding tests on the relevant performance of the electric drive assembly. When all the specified indicators are tested, it can be offline and used. When the electric drive assembly is tested, a corresponding test tray is required to fix the electric drive assembly. The traditional test tray cannot stably and accurately fix the electric drive assembly, and cannot accurately simulate the loading posture, which affects the test effect. Contents of the invention [0003] Based on this, it is necessary to provide a test system, test bench, test tray and suspension device for the electric drive assembly in view of the above ...
