The invention relates to an off-road vehicle front-axle beam lower support. The off-road vehicle front-axle beam lower support comprises a lower support body, wherein the lower support body is a semi-annular structure with an arc cross section, and two side end surfaces of the front-axle beam lower support in the radial direction are respectively provided with an end plate A and an end plate B; a plurality of through holes A are symmetrically formed in the end plate A, and a pair of reinforcing ribs is arranged between the end plate A and the lower support body, and a lightening hole is respectively formed in the lower support body on two ends of the reinforcing ribs; a through hole B is symmetrically formed in two ends of the end plate B, the end plate B is provided with a pair of lug bosses, and a through hole C is formed in each lug boss. The off-road vehicle front-axle beam lower support has advantages that the off-road vehicle front-axle beam lower support is matched with a front-axle beam upper support to use so as to connect a car front-axle beam baffle plate and a retarder shell, the structure adopts a streamline design concept, a plurality of lightening holes are formed in the upper end, when in connection use, the mass of the entire vehicle is reduced, and the loss of oil is reduced; a plurality of end surfaces adopt the combined design of a line segment and an inner arc segment, the right-angled design is avoided, the stress concentration is effectively reduced, and the structure design is very reasonable.
