Abstract

The invention discloses a direct-current motor endurance tester for a new energy bicycle. The direct-current motor endurance tester comprises a main rack body, a fixed motor clamp, a load simulator and a road surface simulator. The load simulator consists of a jacking cylinder and a pressure sensor. The fixed motor clamp includes a fixed rod and a support frame; the middle end of the fixed rod isconnected to the support frame in a rotation manner; and one end of the fixed rod is connected with a to-be-tested motor and the other end is connected with the pressure sensor fixedly. The jacking cylinder is able to apply a load to the to-be-tested motor. The road surface simulator consists of a transmission wheel, an axle, a support column and a magnetic powder brake; the axle is connected to the support column in a rotation manner; the transmission wheel is fixedly connected to the axle; the transmission wheel is abutted against a tire; and the magnetic powder brake is arranged at one endof the axle and is able to provide twisting forces in different directions for the axle, thereby simulating various road surface situations. Therefore, the working environment of the actual working ofthe motor can be simulated and the accuracy of the test result can be improved.

Description

Technical field [0001] The invention relates to the technical field of motor testing, and more specifically, it relates to a DC motor durability testing machine for a new energy bicycle. Background technique [0002] The service life and reliability of the motor are directly related to the service life and safety of the equipment using the motor. Therefore, it is an indispensable link in the motor development process when the motor is tested for durability. Existing new energy bicycles use the motor to be tested as the power source of the new energy bicycle. For the motor to be tested, different working environments and load conditions are two key elements that affect the durability of the motor to be tested. In the working process of the motor to be tested, due to the road conditions during the driving of the vehicle, the motor to be tested is often affected by the bumps caused by the road surface; and during the use of the motor to be tested, due to the load Changes and slope...
