Abstract

The utility model relates to a trailer wheel hub which is composed of a bearing base body, a left bearing support, a right bearing support, a fixed disk, spokes and other parts. The utility model is characterized in that arc face connection is adopted by the connecting places of the bearing seat body and the spokes and the connecting place of the bearing seat body and the fixed disk, and the disadvantages of the low carrying capacity and the easy breaking of the existing right angle type structure wheel hub are overcome. The utility model has the advantages of homogeneous wall thickness, less casting defect, high mechanism intensity, simple manufacturing process, light weight and high rate of finished products, is particularly suitable for vehicles to travel on complicated road surfaces, and carrying capacity is increased by more than 30%.

Description

Trailer hub

The utility model relates to the auto trailer corollary apparatus, especially a kind of four tons of automobile-used trailer wheel hubs.

In order to improve vehicular transport efficient, the independent trailer transportation mode is widely used, wheel hub is a vitals of trailer, it works to accept drive wheels, trailer is wheel hub quiet, the live load that will bear the vertical and horizontal both direction in the process of moving, Gu the size of this its load-carrying capacity directly influences the driving safety and the life-span of independent trailer.Existing independent trailer wheel hub, the joint of the adjacent surface of its each several part adopts structure of right angle tyoe more, and wall unevenness is even, and the foundryman's fever node concentrates on the wall thickness place, easily produces foundry defect, influences its mechanical strength, and the manufacturing cost height, and yield rate is low.Especially vehicle is being turned or during emergency braking because vertically, the unexpected increase of transverse load, usually can exceed the load-carrying capacity of wheel hub, shorten its service life greatly, and the wheel hub fracture easily takes place cause roll-over accident.The most local highways of China are narrow, and bend is many, and car brakeing is more frequent, and existing wheel hub is at structure design, and aspects such as manufacturing process and mechanical strength are all accurate with the situation that adapts to above-mentioned complex road surface and the development of transit industry.

It is a kind of rational in infrastructure that the purpose of this utility model is to provide, and wall thickness is even, and load-carrying capacity is big, the mechanical strength height, and long service life, manufacturing process is simple, and cost is low, is suitable for the trailer wheel hub that various complex road surfaces use.

This trailer wheel hub partly is made up of bearing seat 2, left bearing bearing 11, right bearing bearing 1, reaction plate 8 and spoke 3 etc., and it is characterized in that: the left side of spoke 3 is connected for arcwall face with the joint 4 of bearing seat 2; Reaction plate 8 right sides are followed successively by evagination arcwall face 7 with joint between the bearing seat 2 and are connected with indent arcwall face 5, and described indent arcwall face 5 is provided with plurality of strengthening ribs 6; The counterface 10 of reaction plate 8 is connected for the evagination arcwall face with the joint 9 of bearing seat 2; The cavity 12 of bearing seat 2 inside between left and right bearing brackett also is connected for arcwall face with bearing seat 2 inwalls.Adopt the wheel hub wall of described many places arcwall face structure thin, wall thickness is even, its wall thickness 13-15mm.

Description of drawings of the present utility model is as follows:

Fig. 1 is its cutaway view;

Fig. 2 is its side diagrammatic sketch.

Further describe below in conjunction with accompanying drawing, as shown in drawings, 1 right bearing bearing, 2 bearing seats, 3 spokes, the joint between 4 spokes and bearing seat, indent arcwall face between 5 reaction plates and bearing seat, 6 reinforced ribs, the evagination arcwall face between 7 reaction plates and bearing seat, 8 reaction plates, the joint of 9 counterfaces and bearing seat, 10 ends close end face, 11 left bearing bearings, 12 bearing seat in-to-in cavitys, the screw on 13 spokes, the mounting hole on 14 reaction plates.

4 tons of wheel hubs evenly have 8 screws 13 on its spoke 3 as shown in drawings, use for brake hubs is installed.Evenly have 8 mounting holes 14 on the reaction plate 8, use for steel ring is installed.Evenly have 4 tappedes blind hole around the left bearing bearing 11.According to the wheel hub force analysis, the arcwall face structure of the corresponding joint of adjacent surface of its each several part is mainly used in the increase braking, drives radially torsion load, and the many places arcwall face structure and the reinforced rib 3 of setting have improved its load-carrying capacity greatly.

This wheel hub compared with the prior art advantage is as follows:

The joint of wheel hub each several part adjacent surface all adopts the arcwall face structure, has increased mechanical strength, increases more than 30% through the test bearing capacity, and has prolonged service life.

Rational in infrastructure, wall thickness is even, this wheel hub wall thickness 13-15mm, and existing wheel hub wall thickness is generally 17-30mm, parietal layer is thin, and castings such as pore, shrinkage porosite lack limit and significantly reduce, and are in light weight, technology is simple, the yield rate height, and it is promoted the use of and will improve the safety that vehicle travels at complex road surface greatly.

Claims

1, a kind of trailer wheel hub, it partly is made up of bearing seat 2, left bearing bearing 11, right bearing bearing 1, reaction plate 8 and spoke 3 etc., it is characterized in that:

The left side of spoke 3 is connected for arcwall face with the joint 4 of bearing seat 2; Be followed successively by evagination arcwall face 7 between reaction plate 8 right sides and the bearing seat 2 and be connected with indent arcwall face 5, described indent arcwall face 5 is provided with plurality of strengthening ribs 6; The counterface 10 of reaction plate 8 is connected for the evagination arcwall face with the joint 9 of bearing seat 2; The cavity 12 of bearing seat 2 inside between left and right bearing brackett also is connected for arcwall face with bearing seat 2 inwalls; Adopt the wheel hub wall of described many places arcwall face structure thin, wall thickness is even.
