Abstract
The utility model relates to a supporting structure of a steering assembly part and a half axle assembly part in a light automobile integrated steering drive axle assembly. In order to solve the technical problems that the supporting structure has complicated structure and large volume, and the unsuspended quality of an automobile is increased relatively in the light automobile integrated steering drive axle assembly, the utility model provides the technical proposal of a light automobile integrated steering drive axle assembly with a combined supporting structure; a short ball cage half axle is tightly and fixedly connected with the outer ends of a left inner half axle and a right inner half axle; the external connecting axle head of the short ball cage half axle is tightly and fixedly connected with a connecting axle sleeve; a brake disk is fixedly mounted with an assembly disc at the outer end of the connecting axle sleeve; a steering joint is fixedly sleeved with a bearing pedestal, and is rotationally arranged on the connecting axle sleeve through a biserial taper roller bearing mounted mutually; and a forked bracket for the steering joint at the outer end of an axle shell is fixedly connected through upper and lower ball pins. The supporting structure has the advantages of simple structure, small volume, light unsuspended quality, and simplified important assembly process, and improves the reliability and the traveling smoothness of the four-wheel driven light automobile.
Description
Technical field
The utility model relates to lilliput car Integral steering drive axle assembly.
Background technology
Lilliput car Integral steering drive axle assembly and both sides wheel thereof belong to the non-suspended mass of lilliput car.Present lilliput car Integral steering drive axle assembly, its structure formation mainly comprises front wheel hub, brake wheel, drg, the steering swivel shell, the steering swivel beaded support, axle housing, ball cage semiaxis, main reduction gear and diff etc., wherein, steering swivel shell and drg and steering stub axle be locked connect firmly connect after, constitute the supporting construction component by the fastening steering swivel beaded support that is connected in the axle housing outer face of stub, a left side in certain angle, right swing, front wheel hub is installed in steering stub axle by opposed two tapered roller bearings and puts, ball cage semiaxis is installed in the steering swivel shell, and the axle side gear splined hole in its inner and main reduction gear and the diff closely cooperates, the outer end connects after front wheel hub drives the brake wheel rotation with the front wheel hub flange is fastening.The technical problem underlying that the lilliput car Integral steering drive axle assembly of this supporting construction type exists is: because of the structure of front wheel hub and brake wheel, steering swivel shell and steering swivel beaded support bigger than complexity and volume, make lilliput car have bigger non-suspended mass, when this all-wheel-drive models lilliput car often travels on bad bumpy road surface, two sidecar wheels and road shocks and the impact load that produces increase with the increase of these non-suspended masss, can reduce the reliability and the travelling comfort of lilliput car greatly.
Summary of the invention
Goal of the invention of the present utility model is to simplify the combined support structure that turns to component and semiaxis component, makes its structural volume dwindle, alleviate non-suspended mass and a kind of integral supporting structure lilliput car Integral steering drive axle assembly is provided.The technical scheme of the integral supporting structure lilliput car Integral steering drive axle assembly that the utility model provides, its major technique content is: a kind of integral supporting structure lilliput car Integral steering drive axle assembly, it includes main reduction gear, diff, the semiaxis component, turn to component and axle housing supporting construction, a left side, the right fastening connection short ball in inner shaft outer end cage semiaxis, the outer connection axle head of short ball cage semiaxis and the fastening connection of the assembly opening that connects axle sleeve, brake disc installs with the assembling dish that connects the axle sleeve outer end, steering swivel and bearing seat be suit fixedly, double-row conical bearing rotation through carrying on the back dress mutually is arranged at coupling spindle and puts, and steering swivel is through last, following ball arm respectively with steering swivel fork-shaped bracket upper arm, underarm ball pin connects.
The technical scheme of the utility model integral supporting structure lilliput car Integral steering drive axle assembly, wherein pass through upper and lower ball pin, assemble through double-row conical bearing and semiaxis component again by steering swivel and steering swivel fork-shaped support, formation simplifies the structure, its volume dwindles greatly, non-suspended mass alleviates greatly, thereby effectively reduce the harmful effect of automobile non-suspended mass in bumpy road traveling, thereby the reduction impact loading, the reliability and the travelling comfort of raising all-wheel drive lilliput car; In addition, in the technical program, the bearing support structure design of back of the body dress double-row conical bearing, make full use of liner between the back-to-back double-row conical bearing and adjust the characteristic of end-play, thereby the pre-fastening moment that is carried out when need not to resemble in the existing supporting construction opposed assembling two tapered roller bearings in the front wheel hub adjusts operation, simplified production and assembly technology.
