Description
Technical field
The utility model relates to a kind of steering unit for front wheels of pneumatic tyred roller.
Background technology
At present, domestic front wheel of tire roller steering hardware, mainly contains two kinds and turns to form, and one is that steering cylinder drives front-wheel entirety to turn to, and shortcoming turns to space, Turning radius, turns to friction force larger.Another kind is front-wheel divert packets, Patent Citation CN202169965U, and as shown in Figure 1, operationally, steering cylinder 44 is fixed on swinging mounting 43, and the upper and lower side in the hole on swinging mounting 43 both sides assembles upper end cover 38, lower end cover 37 respectively.The axle head of right support frame 51 and left support frame 36 is arranged in the hole on swinging mounting about 43 limit, carries out axial location by bracing frame end cap 39 and bolt.
This structure solves the front-wheel steering space that the first turns to form, radius and the larger problem of friction force, but this structure swinging mounting and bracing frame connection mode adopt axle sleeve and spindle nose, under pneumatic tyred roller works long hours state, left and right sidesing supporting frame spindle nose and axle sleeve continuous frictional, diameter of axle surface is subject to the squeese pressure of expansion set and the effect of combination machinery power, there is permanent deformation until axle sleeve wearing and tearing, it is malfunctioning that axle sleeve wearing and tearing easily cause roller to turn to, reduce work efficiency, and wearing and tearing are not easily repaired, generally all directly change axle sleeve, and due to axle sleeve and spindle nose be interference fit, disassembling, assembling and replacing is inconvenient, due to building site Uneven road, shimmy of front wheels support is often in the not contour heeling condition in left and right, and therefore spindle nose and axle sleeve can produce flexural deformation, can produce bending resistance when turning to, and such sleeve assembly more easily weares and teares, and steering torque is also larger.
Utility model content
The utility model object is the steering unit for front wheels that the defect existed for prior art provides a kind of pneumatic tyred roller, can bear larger axial, Radial load simultaneously, increases service life and is convenient to maintenance.
The utility model for achieving the above object, adopts following technical scheme: a kind of steering unit for front wheels of pneumatic tyred roller, comprises bridge erecting frame, and its lower end is swung with swinging mounting by bridging spindle and is connected;
The lower-left end of described swinging mounting is fixedly connected with left support frame by the first revolving support, and its bottom righthand side is fixedly connected with right support frame by the second revolving support;
The front side lateral arrangement of described swinging mounting has steering cylinder, and one end of described steering cylinder is arranged in left support frame, and the other end is arranged on described swinging mounting;
The posterior lateral of described swinging mounting is furnished with bar assembly, and one end of described connecting rod assembly is arranged in described left support frame, and the other end is arranged in described right support frame.
Further, the outer ring of described first revolving support is fixed on described swinging mounting by bolt assembly, and its inner ring is fixed in described left support frame by bolt assembly; The outer ring of described second revolving support is fixed on described swinging mounting by bolt assembly, and its inner ring is fixed in described right support frame by bolt assembly.
Further, described connecting rod assembly two ends are fixed in described left support frame and right support frame respectively by Anchor plate kit.
The beneficial effects of the utility model:
1, improve the revolution mode that former pneumatic tyred roller adopts spindle nose to be connected with axle sleeve, adopt single 4 angular contact ball swing bearings to connect; When crankcase ventilaton is walked, shimmy of front wheels support adjusts pendulum angle according to pavement state, due to swing bearing steel ball and arc raceway four point cantact, has certain angle of contact, certain axial moment can be born, solve the friction drag that spindle nose flexural deformation produces.
2, swing bearing is bolted on the support of left and right, easy accessibility, and swing bearing itself can bear larger axial, radial and tilting moment, and reliability is high, and maintenance also only needs to change inner ball, frequency of maintenance and maintenance cost lower.
3, rotation supporting structure is compact, and less space just can realize assembling, therefore, it is possible to reduce front-wheel setting height(from bottom), thus reduce roller front height, the forward visibility of operator's compartment is openr.

Detailed description of the invention
Shown in Fig. 2 to Fig. 4, relate to a kind of steering unit for front wheels of pneumatic tyred roller, comprise bridge erecting frame 1, its lower end is swung with swinging mounting 2 by bridging spindle 3 and is connected.
The lower-left end of described swinging mounting 2 is fixedly connected with left support frame 5 by the first revolving support 41, and its bottom righthand side is fixedly connected with right support frame 6 by the second revolving support 42.
The front side lateral arrangement of described swinging mounting 2 has steering cylinder 11, and one end of described steering cylinder 11 is arranged in left support frame 5, and the other end is arranged on described swinging mounting 2.
The posterior lateral of described swinging mounting 2 is furnished with bar assembly 10, and one end of described connecting rod assembly 10 is arranged in described left support frame 5, and the other end is arranged in described right support frame 6.
Wherein, be easy accessibility, be fixed on described swinging mounting 2 by the outer ring of described first revolving support 41 by bolt assembly 7, its inner ring is fixed in described left support frame 5 by bolt assembly 7; The outer ring of described second revolving support 42 is fixed on described swinging mounting 2 by bolt assembly 7, and its inner ring is fixed in described right support frame 6 by bolt assembly 7.
And described connecting rod assembly 10 two ends are fixed in described left support frame 5 and right support frame 6 respectively by Anchor plate kit 14.
Because left and right sidesing supporting frame is fixedly connected with corresponding tire respectively, when steering cylinder 11 works, steering cylinder 11 drives left support frame 5 to turn to, and drives right support frame 6 to turn to, so just achieve turning to of two groups of tires by left support frame 5 by connecting rod assembly 10.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
