Axlebox retainer key, an assembly including the key and a method of fastening the key

An assembly comprising:

• a pedestal leg of a sideframe of a rail wagon bogie, the leg comprising a side wall incorporating a through-hole and a flange extending from the side wall;
• an axlebox retainer key located on the flange, the key comprising:
• a body having an upper side and an underside;
• a projection which extends from the underside of the body for location in a cavity or a hole formed in the pedestal leg so as to position the key on the pedestal;
• and
• a retaining formation formed at the upper side of the body and defining a transverse groove, which is arranged to extend across the key;
• and
• a fastening arrangement for fastening the axlebox retainer key to the pedestal leg and limiting movement of the axlebox retainer key with respect to the pedestal leg, the fastening arrangement comprising a locking member for securing the key to the pedestal leg when received in the transverse groove, the locking member being an elongate pin which is arranged to be displaced axially when moved into the locking position via the through-hole arranged in the side wall.

An assembly comprising:

A method of fastening an axlebox retainer key to a pedestal leg portion of a sideframe of a rail wagon bogie in which the pedestal leg comprises a side wall and a flange extending therefrom at which the key is located in use, the key comprising:

• a body having an upper side and an underside;
• a locating projection which extends from the underside of the body for location in a cavity or hole which is formed in the pedestal leg;
• a retaining formation formed at the upper side of the body and defining a transverse groove, which is arranged to extend across the key;
• and
• the method comprising:
• locating the projection, which extends from the underside of the body on the key in the cavity or the hole formed in the pedestal leg so as to locate the key in position on the pedestal;
• and
• moving, after the locating, a locking member via a through-hole arranged in the side wall, into the transverse groove extending across the key, and into a locking position to secure the key to the pedestal limiting movement of the key with respect to the pedestal leg.

An axlebox retainer key for fitting to a pedestal leg of a sideframe of a rail wagon bogie, the key comprising:

• a body;
• a locating projection which extends from the body for location in a cavity or hole which is formed in the pedestal leg;
• a retaining formation formed at the body and defining a groove arranged to receive a locking member, in use for maintaining the key at the pedestal leg and limiting movement of the key with respect to the pedestal leg;
• wherein the projection is a basal spigot located on an underside of the body;
• and
• wherein the said groove is arranged on an in use upper side of the body.
