Along with the increasing emphasis on low carbon and environmental protection in recent years, green travel is deeply popularized, electric motorcycles and electric bicycles are widely used, the detection of the motor of the electric vehicle is necessary to be few, the wheel type motor has simple structure, avoids the maintenance problem, has fewer faults and is widely used, and the wheel type motor is characterized in that the motor is part of a wheel hub and cannot be decomposed, a wheel hub body is required to be arranged on a dynamometer for detecting the characteristics of motor power and the like, one end of the wheel type motor is used for being fixed on a frame, the other end of the wheel type motor rotates together with a wheel, and the structural characteristic causes that the motor is difficult to be fixed on the device and rotate together with the dynamometer shaft for detection.
Disclosure of Invention
The purpose of the invention is as follows: the invention provides a wheel type motor dynamometer device, which solves the problem of mounting a wheel type motor on a dynamometer, particularly ensures that a motor rotates stably after being connected with a dynamometer shaft when one side shaft of the motor is long, and the dynamometer can normally detect parameters such as power and the like.
The technical scheme is as follows: the invention discloses a wheel type motor dynamometer device, which comprises a dynamometer and a motor, wherein the motor comprises a short shaft end and a long shaft end; the dynamometer is connected with the long shaft end of the motor through a first connecting mechanism, and the short shaft end of the motor is fixed through a fixing device.
The first connecting mechanism comprises a bearing arranged at the long shaft end of the motor, a connecting cylinder sleeved on the periphery of the bearing and a coupling connected with the connecting cylinder.
One end of the connecting cylinder is connected with the motor through the first fixing mechanism, and the other end of the connecting cylinder is connected with the coupling.
The fixing device is a mounting seat.
The short shaft end of the motor is fixed with the mounting seat through a mounting disc.
The mounting disc is fixed with the mounting seat through a second fixing mechanism.
Has the advantages that: the invention solves the problem that the long shaft end is greatly scratched after the wheel type motor is installed, and solves the defect that the motor and the installation seat are required to be fastened by screws in the traditional motor installation by arranging different connection modes at the long shaft end and the short shaft end of the motor, namely the weight of the motor is supported by a fixing device and a first connecting mechanism; (2) the invention solves the problem that the dynamometer in the prior art is lack of a mounting point when in use, and the first connecting mechanism provides a supporting point for the motor while realizing the connection between the motor and the dynamometer.
