An oscillating arm assembly of mini-size vehicle front axle

The utility model discloses an oscillating arm assembly of a front axle of a miniature vehicle. The ball head end of an oscillating arm and a main body of the oscillating arm assembly of a front axle of a miniature vehicle are designed to two body structures, the lap joints of the ball head end of the oscillating arm and the main body are fixedly connected through fasteners, and fixing holes on lap jointing segments of at least one of the ball head end of the oscillating arm and the main body are bar-shaped holes along the axial line direction of the main body. After the oscillating arm assembly of the front axle with division body structures is used, when the verticality of a front wheel of the miniature vehicle needs to be adjusted, and the length of the oscillating arm is carried out adjustment, as long as a connecting fastener is loosened, the length of the oscillating arm of the front axle can be directly and conveniently adjusted through the bar-shaped fixing holes on the lap jointing segments, and the original complicated maintenance work that the weld is carried out after cut is carried out is eliminated. When the ball head damage occurs, part of a ball head is only carried out replacing and the integral replacement and obsolescence of the oscillating arm of the front axle is eliminated. In this way, raw materials are saved and the replacement and maintenance cost is reduced.
