Abstract

The invention discloses a chassis dynamometer motor base with torque detection and radial cooling functions. The chassis dynamometer motor base comprises a motor base main body; a vertical detection platform and a horizontal detection platform which are fixedly connected with an outer wall reinforcing mechanism are respectively arranged in the middle of the outer wall of the motor base main body;the chassis dynamometer motor base further comprises a first air inlet mechanism, a second air inlet mechanism, a wiring port and a grounding point; and the inner wall of the motor base main body isprovided with a reticular reinforcing structure which is formed by fixedly connecting a first end plate, a second end plate, a reinforcing rib plate and internal axial reinforcing ribs in a crossed manner. According to the invention, by arranging the inner and outer reinforcing ribs, the structural strength is improved; a detection platform is directly reinforced; the weights of the external reinforcing ribs and the internal reinforcing ribs are far less than the weight of the thickened motor base main body due to the same effect; ventilation grooves are formed in part of the internal axial reinforcing ribs, so that the heat dissipation performance is improved; cooling is facilitated through cooperation of the first air inlet device, the second air inlet device and the gap between the reinforcing rib plate and the motor base main body; and the overall power density of the motor is greatly improved.

Description

technical field

[0001] The invention relates to the technical field of motor bases, in particular to a chassis dynamometer motor base with functions of torque detection and radial cooling. Background technique

[0002] The standard GB755 has clear regulations on the vibration and temperature rise limits of rotating motors, but there is no corresponding regulation on chassis dynamometer motors. Therefore, there are certain difficulties in the measurement and control of the vibration and temperature of the chassis dynamometer motor, especially for large-scale chassis dynamometer motors. The detection platform is connected to the torque detection device. The position change will cause the output data of the torque detection device to be abnormal, and the real data cannot be obtained. The conventional design scheme in this field has no radial air passage structure, the stator core is directly connected to the shroud, and the heat dissipation mainly depends on the forced heat di...
