Embodiment Construction

[0027] In order to make the purpose, content, and advantages of the present invention clearer, the specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0028] The present invention provides a torque sensor for a testable fan, which also has the function of a fan transmission component. Such as figure 1 and 3 As shown, the sensor includes: a signal acquisition and processing module 1 , a flange 2 , a high-speed slip ring 3 , and a speed measuring device 4 . The fan includes fan blades 11 and a rotating shaft 12 , the inner wall of the rotating shaft 12 is connected with the outer wall of the signal acquisition and processing module 1 .

[0029] The protruding part of the sensor bracket (not shown) fixes the edge stopper of the stator of the high-speed slip ring 3, so that the stator will not rotate with the rotor. The sensor of speed measuring device 4 is installed ...

Abstract

The invention discloses a torque sensor for testing a vehicle fan. The vehicle fan comprises fan blades and a rotating shaft; the torque sensor comprises a signal acquisition and processing module, a flange plate, a high-speed slip ring and a speed measuring device which are coaxially connected in sequence; and the inner wall of the rotating shaft is connected with the outer wall of the signal acquisition and processing module. By adoption of the torque sensor disclosed by the invention, the rotating speed and the torque of the vehicle fan, namely a cooling fan, in a real vehicle working state can be tested online under the circumstance that the existing assembly structure of a vehicle is kept unchanged.

Description

technical field [0001] The invention relates to a torque sensor, in particular to a torque sensor for testing a vehicle fan. Background technique [0002] Some special vehicles have high requirements for heat dissipation, and the working condition of the fan as the main heat dissipation component is directly related to the power output effect of the vehicle. The cooling performance of existing cooling fans is obtained by combining bench tests and design calculations, and the data of the car in its real working state is difficult to measure. Once there is a problem with the heat dissipation parts of the vehicle, all the working parameters of the cooling fan can only be calculated through theoretical analysis, and there is no real data to rely on. [0003] Therefore, there is an urgent need to provide a new type of fan torque sensor, which can be used as a component of the fan transmission, and can also test the speed and torque on-line under the working condition of the fan ...
