Abstract

PURPOSE:To enable formation of a rotor core of a dynamometer by using a plurality of coupling members comprising a pipe halved axially on an internal surface of a roller when the core is mounted on the internal surface of the roller to make heat generated therein hard to transmit to the roller. CONSTITUTION:A roller body 19 and a rotor core 22 are fastened by a plurality of coupling members 23. The coupling member 23 is so arranged that an internal surface of the roller 19 is fastened to the part of an arc of a pipe halved axially while a rotor core 22 is fastened on a part of the pipe sectioned. With such an arrangement, a clearance is formed between the roller 19 and the core 22 to let cooling air pass so that heat released from the core 22 is kept to transmit to the roller 19. In addition, as the roller 19 and the core 22 are connected with the coupling member 23 comprising the pipe divided in two, cooling air also passes through the coupling member 23 to cool. This minimizes the possibility of heat from the core 22 transmitting to the roller 19 through the coupling member 23 thereby preventing adverse effect to the tire of a vehicle to be tested.

C6 Conventional technology Chassis dynamometers used for vehicle performance tests (running resistance, climbing boards, vehicle weight, etc.) can easily carry out experiments indoors with good reproducibility that are equivalent to driving on the actual road. It is widely used for testing exhaust gas characteristics and fuel consumption characteristics. However, in its use, there are many matters that must be managed, including the settings of the input and driving torsional forces, and therefore, if this management is inappropriate, a satisfactory simulation cannot be performed. One of the factors is rotational torsion force control. Conventionally, this control has been performed by connecting a direct current machine (DC dynamometer) and a roller.

11. When attaching the rotor core of the dynamometer to the inner circumferential surface of the roller, a connecting member consisting of a pipe divided into two in the axial direction was used on the inner circumferential surface of the plurality of rollers. Since this connecting member has an eave shape that divides the pipe into two in the axial direction, it has a large surface area, which improves heat dissipation and prevents the heat generated in the rotor core from being transmitted to the rollers.

As shown in FIG. 3, this coupling member 23 is configured to fix the inner circumferential surface of the roller body 19 to the arc portion of the pipe divided into two, and fix the rotor core 22 to the cross-sectional portion of the pipe. be done. As shown in FIG. 3, by providing eight coupling members 23 between the roller body 19 and the rotor core 22, a gap is created between the roller body 19 and the rotor core 22 through which cooling air passes, so Heat radiation from the child core 22 is no longer transmitted to the roller body 19. In addition, since the roller body 19 and the rotor core 22 are connected by a connecting member 23 made of two divided pipes, the cooling air flows through the connecting member 23.
The rotor core 22 also passes through the interior of the rotor core 22 to cool it.
