Description
Technical field
The utility model relates to a kind of non-maintaining end pattern front steering axle assembly of taking turns with plate disc brake structure.
Background technology
In producing and selling on the existing home market/front steering axle assembly that heavy duty truck, big/medium bus use in wheel end inner structure generally adopt two independently single-row tapered roller bearing supporting structure patterns.Adopt the characteristics of existing type structure:
1, simple in structure, with low cost, but in assembling, adjustment process is very loaded down with trivial details and can not guarantee in the scope of play at optimum of inside and outside two tapered roller bearings of wheel hub; Most of producer mainly carries out according to empirical value in the adjustment assembling; Because the play of bearing directly influences the service life of bearing; Simultaneously, be different to the play value of taking turns side bearing in the different front steering axle assemblies that adopt same batch of isostructure, namely conformability is very poor; So adopt do not have conformability the service life of this airframe bearing and be difficult to predict the concrete time in service life.Fault rate is higher.
2, outer bearing adopts grease lubrication or oil lubrication in the wheel hub; Need the periodical maintenance maintenance in operational process, produce Master Cost and labour cost is a very big expenditure in the car load life cycle, the improper meeting of maintaining is produced and is wholely taken turns the end damage of components or scrap.Simultaneously, a large amount of waste oil, the degras that change do not recycle, and are a kind of destruction to environment yet.
Along with the raising of parts processing technology level, car load factory progressively promote the safety of parts and the requirement of stability requirements for quality, the terminal client of parts; By the integration to the inside and outside bearing arrangement of wheel hub, it is feasible making the wheel end branch avoid safeguarding.
Summary of the invention
The purpose of this utility model provides that a kind of mounting structure is simple, steady quality is reliable, fault rate is low, the non-maintaining end pattern front steering axle assembly of taking turns with plate disc brake structure of long service life.
For solving above-mentioned purpose, the technical solution of the utility model is: a kind of non-maintaining end pattern front steering axle assembly of taking turns with plate disc brake structure, comprise front axle and two non-maintaining end assemblies of taking turns, described two non-maintaining wheels hold assembly to be installed in the two ends, the left and right sides of front axle respectively by steering swivel, described steering swivel is provided with track rod lever, disk brake assembly and drag link arm, two track rod levers connect by tierod about described, described disk brake assembly comprises plate disc brake and the brake disc that can engage mutually, described brake disc is installed on the Hub assembly, the described non-maintaining end assembly of taking turns comprises wheel hub and is arranged on the interior hub bearing group of wheel hub, described hub bearing group is combined by two tapered roller bearings, and its two ends are provided with oil sealing and inner repack with grease.Two hub bearing groups of being combined into of tapered roller bearing independently, play between its bearing passes through in parts production, be adjusted in the fitting process in the optimized scope, its conformability is better, prolonged the service life of bearing, improve quality stability and the reliability of whole vehicle bridge, reduced fault rate, the grease that bearing inside is pre-charged with, make to be assembled into and in use need not behind the axle assembly additionally to change and add lubricating oil, the purpose of maintenance is exempted from realization, more oil change has not reduced the expenditure of expense yet, avoid the waste oil changed, the destruction that degras etc. cause environment, the non-maintaining wheel of the utility model holds the mounting structure of pattern front steering axle assembly also simpler simultaneously.
As further improvement of the utility model, described hub bearing group is fitted in the wheel hub by interference fit.Interference fit guarantees outer ring and the wheel hub no-float of tapered roller bearing, can not relatively rotate.
Further improve as of the present utility model, described plate disc brake is the plate disc brake of compression air brake.The plate disc brake brake efficiency height of compression air brake, excellent performance, intelligent compound ability is strong, and is simple in structure.
In sum, the beneficial effects of the utility model are: the wheel hub axial dimension shortens, and reduces front steering axle assembly quality; Bearing clearance value in the hub-bearing unit remains in the optimized scope always, and service property (quality) is stable, reliable; Long service life; The hub-bearing unit measured lubrication fat of annotating in advance, use amount seldom and without secondary is changed; Reduce the use amount of grease; Hub-bearing unit in use avoids care and maintenance, reduces terminal user's use cost and stops class's loss.
