Abstract
The utility model discloses a single-stage reduction driving bridge for a heavy truck. The single-stage reduction driving bridge for the heavy truck provided by the utility model uses the technical scheme: the single-stage reduction driving bridge for the heavy truck comprises a hub, a bridge shell assembly and a half shaft, wherein the hub is assembled at a position of a shaft head of the bridge shell assembly through a bearing unit; the hub is fixedly connected with the half shaft through bolts; the hub is fixedly connected with a braking plate through bolts; the braking plate is matched with a plate type brake; the plate type brake is fixedly mounted on a braking flange; and the braking flange is fixedly mounted on the bridge shell assembly. The single-stage reduction driving bridge for the heavy truck provided by the utility model has the beneficial effects in that the hub and the bearing unit are matched at a rim; compared with the traditional bearing cross type arrangement structure, the structure provided by the utility model is greatly simplified, so that the assembly difficulty is reduced, and the assembly speed is accelerated on the basis of improving the quality of the bridge shell assembly; and the braking plate and the hub are integrally connected through bolts. Therefore, the single-stage reduction driving bridge for the heavy truck has the advantages of simple structure, high component generality, high transmission efficiency and the like.
Description
Technical field
The utility model is a kind of heavy card singl-reduction axle, belongs to field of automobile.
Background technology
The drive axle assembly is positioned at the end of automotive transmission, and its basic training is with being the torque that increases to be come by the transmission shaft transmission, to the left and right driving wheel, and makes the left and right driving wheel have differential function torque distribution; Simultaneously, drive axle also will bear vertical force, longitudinal force and transverse force and the moment thereof that acts on road surface and vehicle frame.Heavily card in the market is mainly to adopt drum brake mechanism with singl-reduction axle, exists rate of braking not enough, and the shortcomings such as easy fading of brake can not satisfy high-end heavy card designing requirement.
Summary of the invention
The utility model provides the technical scheme of a kind of heavy card with singl-reduction axle for the deficiencies in the prior art, this programme coupling plate disc brake, and its lock torque is large, good stability.
The utility model is realized by following technical measures: a kind of heavy card singl-reduction axle, comprise wheel hub, axle case assy, semiaxis, described wheel hub is assemblied in the spindle nose position of axle case assy by bearing unit, described wheel hub and semiaxis are bolted to connection, described wheel hub has been bolted to connection brake disc, described brake disc coordinates with plate disc brake, and described plate disc brake is fixedly mounted on the braking flange, and described braking flange is fixedly mounted on axle case assy.
Concrete characteristics of the present utility model also have, above-mentioned bearing unit by jam nut and thrust washer axial location on the spindle nose of axle case assy.
The beneficial effects of the utility model are: the technical program adopts at wheel limit coupling hub-bearing unit, and more traditional bearing formula arrangement structure that bridges is greatly simplified, and has reduced assembly difficulty on the basis of improving the axle case assy quality, has improved assembling speed; Brake disc and wheel hub are with bolts to be integrated.Summary: it has simple in structure, parts commonality and reaches well the driving efficiency advantages of higher.
