Abstract
A reactor apparatus for a railway vehicle includes a coil assembly, a side cover, through bolts inserted into the coil assembly, cover supporting members, a pair of frames, and ribs that reinforce the pair of frames. A support/fixation section of each frame is fixed to an under surface of a vehicle pedestal. The pair of the frames are disposed on both sides of the coil assembly, and support the through bolts and the cover supporting member. For each rib, leg members that extend from corresponding reinforcing body are penetrated into and welded to the corresponding frame. For each cover supporting member, a leg member that extends from corresponding cover supporting body is penetrated into and welded to the corresponding frame.
Claims8
A reactor apparatus for a railway vehicle comprising:
- a coil unit that operates as a reactor;
- a cover that covers the periphery of the coil unit;
- a coil supporting member that is inserted into the coil unit;
- a cover supporting member that is attached to the cover;
- a pair of frames that are disposed on both sides of the coil unit by fixing a support/fixation section bent into an L-shaped cross-sectional portion to an under surface of a vehicle pedestal, supports the coil supporting member, and supports the cover supporting member;
- and
- a reinforcing member that is provided on the support/fixation section of each of the frames and reinforces the L-shaped cross-sectional portion, wherein
- the reinforcing member includes a reinforcing body that abuts against the L-shaped cross-sectional portion and a leg member that extends from the reinforcing body to penetrate the frame, the leg member being welded to the frame at a side opposite to the inserted side, and
- the cover supporting member includes a cover supporting body that is fixed to the cover and a leg member that extends from the cover supporting body to penetrate the frame, the leg member being welded to the frame at a side opposite to the inserted side.
