Undercarriage for armored personnel carrier

摘要

An armored personnel carrier (10) includes a hull (14) supported on two undercarriages (12). Each undercarriage (12) includes a primary frame (22) and a plurality of secondary frames (26) which in turn carry wheel members (28). The secondary frames (26) are urged to pivot away from the primary frame (12) by spring mechanisms (38). The center secondary frames (26c) are each biased outwardly by two spring mechanisms (38) while the endmost secondary frames (26e) are biased outwardly by a single spring mechanism (38). The wheel members (28) are driven by a drive mechanism (64), a primary transmission (58) enclosed within the primary frame (22) and a plurality of secondary transmissions (82) each enclosed within one of the secondary frames (26).
