Abstract
The invention provides a single-stage speed reduction driving axle for a heavy truck. The single-stage speed reduction driving axle for the heavy truck has the technical scheme that the single-stage speed reduction driving axle for the heavy truck comprises a wheel hub, an axle case assembly and a half axle, wherein the wheel hub is assembled at the axle end position of the axle case assembly through a bearing unit, the wheel hub and the half axle are fixedly connected through a screw bolt, the wheel hub is fixedly connected with a braking disc through a screw bolt, the braking disc is matched with a disc type brake, the disc type brake is fixedly arranged on a braking flange, and the braking flange is fixedly arranged on the axle case assembly. The single-stage speed reduction driving axle for the heavy truck has the beneficial effects that according to the technical scheme, a wheel hub bearing unit is adopted to be matched at the wheel rim, the structure is greatly simplified through being compared with the traditional bearing span type arrangement structure, the assembly difficulty is reduced on the basis of improving the quality of the axle case assembly, the assembly speed is accelerated, and the braking disc and the wheel hub are connected through the screw bolt. Therefore the single-stage speed reduction driving axle for the heavy truck has the advantages that the structure is simple, the universality of components is good, the transmission efficiency is high, and the like.
Description
Technical field
The present invention is that one is heavily blocked with singl-reduction axle, belongs to field of automobile.
Background technology
Drive axle assembly is positioned at the end of automotive transmission, and its basic training is with being to increase by transmission shaft to transmit the torque coming, and to left and right driving wheel, and makes left and right driving wheel have differential function torque distribution; Meanwhile, drive axle also will bear vertical force, longitudinal force and the transverse force and the moment thereof that act on road surface and vehicle frame.Heavily card is in the market mainly to adopt drum brake mechanism with singl-reduction axle, has rate of braking deficiency, and the shortcomings such as easy fading of brake, can not meet high-end heavy card designing requirement.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, a kind of technical scheme of heavy card singl-reduction axle is provided, this programme coupling plate disc brake, its lock torque is large, good stability.
The present invention realizes by following technical measures: one is heavily blocked with 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 braking flange, and described braking flange is fixedly mounted on axle case assy.
Concrete feature of the present invention also has, above-mentioned bearing unit by jam nut and thrust washer axial location on the spindle nose of axle case assy.
Beneficial effect of the present invention is: the technical program adopts at wheel limit coupling hub-bearing unit, and more traditional bearing formula arrangement structure that bridges is greatly simplified, and on the basis of improving axle case assy quality, has reduced assembly difficulty, has improved assembling speed; Brake disc and wheel hub are with bolts to be integrated.Summary: its have simple in structure, parts commonality is good and driving efficiency advantages of higher.
