Electric vehicle torque induction measuring motor

Abstract

The invention provides an electric vehicle torque induction measuring motor including a motor shaft roller, and a motor stator part and a motor rotor part sleeving the motor shaft roller, the motor rotor part is connected with a first bearing, the periphery of the motor shaft roller is sleeved with a torque induction device, the torque induction device includes a fixed part, a movable part, and a transition part, and at least one force sensor arranged between the fixed part and the movable part for sensing the relative displacement of the fixed part and the movable part, the fixed part is connected to the motor shaft roller, the movable part and the motor rotor part are connected via the first bearing, the fixed part and the movable part are connected via the transition part, the motor rotor part is connected with a load connection part, and the load connection part is connected with an outside force device or part. Except integrating a torque measuring device in a motor, a speed measuring device is also integrated in the motor, the torque signal and the speed signal of foot operation can be simultaneously sensed, the hidden safety trouble of single torque can be solved, the riding comfort level and safety can be greatly improved, the wiring is simple, and the maintenance and replacement are convenient.

Description

technical field [0001] The invention relates to an electric vehicle torque induction measuring motor, in particular to an electric vehicle torque and speed integrated measuring device. Background technique [0002] In the prior art, most of the sensors of electric bicycles are independent components, such as central shaft type torque, claw type torque, and disk type torque. These split sensors are very complicated in structure and assembly for the whole vehicle, and the installation of each component is very complicated. For different parts of the whole vehicle, this solution affects the cleanliness of the whole vehicle, cumbersome installation, long leakage and long wiring, troublesome after-sales service, and potential safety hazards. Contents of the invention [0003] The object of the present invention is to provide a torque induction measuring motor for an electric vehicle that simultaneously senses torque and speed. [0004] The present invention achieves the above ...
