Overhead front axle assembly for disc brake of truck

Abstract

The invention provides an overhead front axle assembly for a disc brake of a truck. The overhead front axle assembly comprises a front axle, disc brakes, hubs, steering knuckles, steering knuckle arms, transverse pull rod arms and longitudinal pull rod arms, wherein a plurality of openings are integrally formed in the outer edge of the disc surface of each hub so as to form a corrugated structureon the outer edge of the disc surface of the hub, and a plurality of hollow holes are integrally formed in a transverse H-shaped beam part of the front axle; and left wing plates are integrally arranged on one sides of the initial ends of steering knuckle shaft heads, right wing plates are integrally arranged on the other sides of the initial ends of the steering knuckle shaft heads, a bi-metal lining is arranged in a connecting hole of one fork arm in each steering knuckle, an FAG needle bearing is arranged in a connecting hole in the other fork arm in each steering knuckle, and framework oilseals are arranged at the joints between main pin holes and the connecting holes. The overhead front axle assembly is simple in structure and convenient to use; by utilizing the overhead disc brake,the distribution of the longitudinal pull rod arms is promoted, and an inner corner is enlarged, so that the front axle and the hubs are effectively lightened, the connection strength of the transverse pull rod arms and the longitudinal pull rod arms is increased, and the problems that the corner resistance is large, and a steering wheel is joggled are solved.

Description

technical field [0001] The invention relates to the technical field of auto parts manufacturing, in particular to a truck disc brake overhead front axle assembly. Background technique [0002] The truck front axle brake assembly in the prior art is usually a drum brake. Its structure is composed of a clutch, a steering knuckle, a wheel drum and a half shaft. It is connected with the clutch, the rear end of the half shaft is connected with the rotating shaft placed in the front axle through the cross universal joint, and the wheel drum is connected with the outer circular surface of the steering knuckle through the bearing. Furthermore, for the steering knuckle part, the steering knuckle is one of the important parts on the front axle of the truck. Its main function is to bear the load on the front of the car, support and drive the front wheels to rotate around the kingpin to make the car turn. At present, the front axle of domestic trucks When matching disc brakes, a spec...
