Special test device for new energy automobile hub motor, and test method thereof

Abstract

The invention discloses a special test device for a new energy automobile hub motor. The special test device comprises a base and a supporting seat, the supporting seat is horizontally arranged abovethe base, the supporting seat is connected with the top of the base through a plurality of damping shock absorbers, a device chamber is arranged in the base, a controller, a power source, a servo motor and an indicator lamp are sequentially arranged in the device chamber, and an output end of the controller is respectively connected with the indicator lamp and an input end of the servo motor. Thetest method comprises the following steps: step 1, firstly fixing the base via a locking block, and then inserting the hub motor into a through opening; step 2, then turning on the servo motor throughthe controller, and adjusting the height of the device; and step 3, driving a slide block to move by using a turnbuckle so as to drive a bearing plate to perform auxiliary support on the hub motor through a guide rod. According to the special test device disclosed by the invention, by setting a plurality of adjustment mechanisms, the device can freely adjust the height and the angle, so that thetest effect of the device on the hub motor is improved.

Description

technical field [0001] The invention relates to the technical field of testing equipment, in particular to a special testing equipment for a hub motor of a new energy vehicle and a testing method thereof. Background technique [0002] The driving form of the next generation of vehicles must be the distributed drive of hub / wheel motors, which can improve transmission efficiency, simplify the chassis structure, and improve vehicle power, economy and stability. However, there are still many technical bottlenecks for in-wheel motors used in electric vehicles in terms of power density improvement, regenerative braking energy recovery, and high reliability under complex driving conditions. So far, there has been no mass production of in-wheel motors. Distributed drive electric vehicles. In order to solve these technical bottlenecks, it is necessary to study and analyze the driving / braking characteristics of the in-wheel motor under the actual driving conditions of the real vehicl...
