流式減速装置が使用されている。Conventional technology In addition to the main brake (foot brake) and the auxiliary exhaust brake (exhaust brake), the deceleration or braking device for large vehicles provides stable deceleration when descending a long slope, and prevents burnout of the brakes. Eddy current reduction devices are used to prevent this.

不利である。また制動０８時は連続通電しておく必要が
あり、バッテリの電力消耗が激しいためバッテリ容量の
増大及び発電機能力の増強が必要となる。Problems to be Solved by the Invention Conventional eddy current reduction gears use electromagnets with electromagnetic coils wound around iron cores as magnetic poles, so they are heavy and have large external dimensions, so they cannot be used in vehicle towers with limited space. This is disadvantageous. Further, during braking at 08:00, it is necessary to keep the power flowing continuously, and the power consumption of the battery is severe, so it is necessary to increase the battery capacity and enhance the power generation function.

枠とを相対的に所定角度回動自在に設けてなる。Means for Solving the Problems In order to achieve the above object, the eddy current reduction device of the present invention has a pair of rotors whose disk surfaces face each other with a distance between them, which are fitted onto a rotating shaft, and a gap is formed between the disk surfaces. A plurality of switch plates made of fan-shaped ferromagnetic material facing each other are installed at a distance from a switch plate support frame made of a non-magnetic material and pivotally supported on the rotating shaft, and the individual switch plates are magnetically opposed to each other. A plurality of permanent magnets having the same shape as the switch plate are mounted in a donut-shaped non-magnetic permanent magnet support frame with opposite polarity, which is insulated and disposed circumferentially, and is pivoted on the switch plate support frame between the switch plate groups on both sides. The switch plate support frame and the permanent magnet support frame are arranged circumferentially, with both side magnetic pole faces facing the switch plate group, and are provided so as to be relatively rotatable at a predetermined angle.

くすると共に、円滑な回動を確保できる。In addition, it is desirable that there be no gap between the above-mentioned switch plate and the magnetic pole surface of the permanent magnet in terms of the magnetic circuit configuration, but if there is strong contact, it will be difficult to rotate, so a thin plate of ferromagnetic Oiles metal is used as the la pole. By attaching it to the surface, it eliminates the gap with the switch board and ensures smooth rotation.
