Model railroad truck having polymer spring

Abstract

A truck for use on a model railroad car, in association with plural axle/wheel sets, includes a left truck side frame and a right side frame, each having a bolster receiver therein; an elongate bolster extending between said right frame half and said left frame half, wherein each end of said bolster is received in said bolster receiver of a truck side frame; and a polymer spring member received in each of said bolster receivers between a bottom surface of said bolster receiver and a bottom surface of a bolster end for (1) retaining the bolster in the bolster receiver, and (2) allowing limited torsion of said left truck frame and said right truck frame relative to one another and to said bolster.

1 . A truck for use on a model railroad car, in association with plural axle/wheel sets, comprising:
 a left truck side frame and a right truck side frame, each having a bolster receiver therein;   an elongate bolster extending between said right frame half and said left frame half, wherein each end of said bolster is received in said bolster receiver of a truck side frame; and   a polymer spring member received in each of said bolster receivers between a bottom surface of said bolster receiver and a bottom surface of a bolster end for (1) retaining the bolster in the bolster receiver, and (2) allowing limited torsion of said left truck frame and said right truck frame relative to one another and to said bolster.   
   
   
       2 . The truck of  claim 1  wherein said polymer spring member is molded with spring aesthetics thereon. 
   
   
       3 . The truck of  claim 1  wherein said polymer spring member is molded with coil spring aesthetics thereon. 
   
   
       4 . A truck for use on a model railroad car, in association with plural axle/wheel sets, comprising:
 a left truck side frame and a right truck side frame, each having a bolster receiver therein;   an elongate bolster extending between said right frame half and said left frame half, wherein each end of said bolster is received in said bolster receiver of a truck side frame; and   a polymer spring member, molded with spring aesthetics thereon, received in each of said bolster receivers between a bottom surface of said bolster receiver and a bottom surface of a bolster end for (1) retaining the bolster in the bolster receiver, and (2) allowing limited torsion of said left truck frame and said right truck frame relative to one another and to said bolster.   
   
   
       5 . The truck of  claim 4  wherein said polymer spring member is molded with coil spring aesthetics thereon.
