The invention discloses a lower suspension arm bushing mounting structure of a Macpherson suspension. The lower suspension arm bushing mounting structure comprises an auxiliary frame, wherein an upward auxiliary frame bushing mounting plate is mounted at the front end of the auxiliary frame, and an outward lower suspension arm is mounted on the auxiliary frame bushing mounting plate and the auxiliary frame and is A-shaped; one supporting foot of the lower suspension arm is fixed with the side wall of the auxiliary frame, and a reinforced support is buckled outside another supporting foot from top to bottom; the reinforced support comprises a left vertical plate and a right vertical plate which are symmetrically fixed at the two ends of a connecting plate, and a plurality of bolt holes on one straight line are symmetrically distributed on the left vertical plate and the right vertical plate; a lower suspension arm bushing is buckled at the outer part of the reinforced support, and the reinforced support further comprises a plurality of locking bolts in one-to-one correspondence with the bolt holes; the lower suspension arm bushing is connected and fixed with the auxiliary frame bushing mounting plate or the auxiliary frame through the locking bolts. Due to the clever structural design, the strength and stiffness of connecting points are increased, the stress at the bolt locations is shared, the service life of mounting points is prolonged, and the damage risk brought by stress concentration is reduced.
