Abstract
A frameless self-steering radial wheeled support vehicle for a railroad car body includes: (a) a pair of wheelsets, (b) a support at opposite ends of each wheelset for independently mounting a railroad car body on each end of the wheelset, (c) resilient shear pads for mounting each support upon an end of a wheelset, which pads permit both lateral and yaw movement of a wheelset relative to its supports, and (d) a linkage connecting adjacent ends of each wheelset constraining the wheelsets to yaw in opposite sense and permitting lateral movement of one wheelset relative to the other.

A frameless self-steering radial wheeled support vehicle for a railroad car body including:
- (a) a pair of wheelsets,
- (b) a support at opposite ends of each wheelset for independently mounting a car body on each end of the wheelset,
- (c) resilient means for mounting each support upon an end of a wheelset, which resilient means permits both lateral and yaw movement of a wheelset relative to its supports, and
- (d) a linkage connecting adjacent ends of each wheelset and constraining the wheelsets to yaw in opposite sense and permitting lateral movement of one wheelset relative to the other, said linkage including a yaw connection between adjacent ends of each wheelset and across vehicle connection between yaw connections.
A frameless self-steering radial wheeled support vehicle for a railroad car body including:
- (a) a pair of wheelsets,
- (b) a support at opposite ends of each wheelset for independently mounting a car body on each end of the wheelset,
- (c) resilient means for mounting each support upon an end of a wheelset, which resilient means permits yaw movement of a wheelset relative to its supports, and
- (d) a linkage connecting adjacent ends of each wheelset and constraining the wheelsets to yaw in opposite sense relative to each other, said linkage further permitting both wheelsets to yaw in the same direction with respect to the car body.
A frameless self-steering radial wheeled support vehicle for a railroad car body including:
- (a) a pair of wheelsets,
- (b) a support at opposite ends of each wheelset for independently mounting a car body on each end of the wheelset, said support including frictional resistance means providing for restrained lateral movement between said support and the car body, and
- (c) resilient means for mounting each support upon an end of a wheelset, which resilient means permits lateral movement of a wheelset relative to its supports.
