The invention discloses a partial pendulum and steering mechanism for partial pendulum form vehicle, the main vehicle skeleton includes a front support, a main beam, the upper part of the main beam has a top end extended segment, the top end extended segment and the main beam are integrated into one form, a front steering upright column sleeve canister is provided on the top end extended segment, the shaft thread of the front steering upright column sleeve canister and the shaft thread of a shaft bearing groove on the main beam are collinear, a half open form front steering upright column runs through the front steering upright column sleeve canister and the bottom of the half open form front steering upright column and connects with a shaft bearing provided inside the shaft bearing groove, the top end of the half open form front steering upright column is provided with a vehicle handle, the vehicle handle at the side wall of the half open form front steering upright column stretches out a connection rod, the connection rod is connected with a pin shaft in the middle of a universal steering mechanism. The partial pendulum and steering mechanism for partial pendulum form vehicle, with the structure of half open form front steering upright column, makes the main beam have an upward extending space, thereby increases the functional load bearing ability of the main beam, makes the overall structure of the partial pendulum and steering mechanism compact, and lowers production cost.
