Abstract
A driving device of a rear wheel for a tyre road roller comprises a real wheel frame (1), a coupling plate (2), a reducer (3), two middle wheels (4 2) and two side wheels (4 1) arranged at the both sides of the middle wheels (4 2). The reducer (3) is arranged on the rear wheel frame (1) via the coupling plate (2). The driving device is characterized in that a side wheel rim (4 1 1) of the side wheels (4 1) is connected with an output end of the reducer (3) and the side wheel rim (4 1 1) is connected with a middle wheel rim (4 2 1) of the middle wheels (4 2) via a connection component (5).
Description
Technical field
The utility model relates to the field of road engineering machinery field, relates in particular to the rear wheel drive device of rubber-tyred roller.
Background technology
As shown in Figure 1, in existing rubber-tyred roller rear wheel drive assembly, the one, maintenance and maintenance be difficulty very.Reductor 3 is an one with rim assembly 9 usefulness Bolt Connection, must pull down reductor 3 when rim assembly 9 being overhauled and safeguard, and two tire 4 shared rim assemblies 9, is not easy to dismounting, and maintenance process is very complicated, is easy to cause new fault.The 2nd, the more change poles inconvenience of tire 4.When re-type 4, want earlier from vehicle frame 10 dismounting water tanks 11, take the coupling bolt of rear wheel frame 1 apart, rear wheel frame 1 is all disassembled from vehicle frame 1 together with whole rear wheel assembly, then the machine oil in the reductor 3 is emitted, pull down tie-plate 2 and semiaxis 12 etc., just can change tire 4 at last, total loading and unloading expend time in and reach 8 to 12 hours, if maintenance of equipment is incomplete, the rear wheel assembly of pulling down be reinstalled especially unusual difficulty.
The utility model content
The technical problems to be solved in the utility model is to overcome the deficiencies in the prior art, and the rear wheel drive device of adjustment, easy to maintenance, the rubber-tyred roller that can reduce maintenance time is provided.
The rear wheel drive device of rubber-tyred roller of the present utility model, comprise rear wheel frame, tie-plate, reductor, two breast wheels and two side wheels that lay respectively at the breast wheel both sides, reductor is installed on the rear wheel frame by tie-plate, the side wheel wheel rim of described side wheel links to each other with the output of reductor, and the side wheel wheel rim links to each other by connector with the breast wheel wheel rim of breast wheel.
Be equiped with bearing support on the breast wheel wheel rim of described breast wheel, be equiped with axle by a holder on the rear wheel frame, the bearing support of two breast wheels is supported in the both ends of axle respectively.
Described connector is a spline housing, and bearing support is provided with external splines, and connector is connected by spline with bearing support.
The rear wheel drive device of rubber-tyred roller of the present utility model, possess assembling, adjustment, keep in repair all advantage very easily, the trailing wheel wheel rim of rubber-tyred roller becomes four by original two, the wheel rim of side wheel and breast wheel links to each other by the connector of band internal spline and the bearing support of band external splines, realize the transmission of driving force, guaranteed that four trailing wheels can both obtain driving moment, the dismounting of trailing wheel and installation are become flexibly, simply, can save a large amount of dismounting time, be convenient to realization portion dress and continuous productive process, help enhancing productivity.The operation of parts such as maintenance tire, reductor and re-type also becomes more simple, changes the tire of middle groups if desired, only need take a holder and connector apart, and the whole middle groups of releasing is also changed; Two tires about changing if desired, after releasing middle groups, can directly dismantle, and change any one tire and do not need to dismantle bearing, reductor, hydraulic motor and pipeline thereof, no longer need to take apart rear wheel frame, more do not need to pull down parts such as water tank, so not only saved the time but also reduced the possibility that produces new fault, helped improving the reliability of system, the convenience of maintenance.The rear wheel drive device of rubber-tyred roller of the present utility model has improved maintenance efficiency greatly, and practicality is good, compact conformation, and economic benefit is obvious.

The specific embodiment
As shown in Figure 2, the rear wheel drive device of rubber-tyred roller of the present utility model, comprise rear wheel frame 1, tie-plate 2, reductor 3, two breast wheels 42 and two side wheels 41 that lay respectively at breast wheel 42 both sides, reductor 3 is installed on the rear wheel frame 1 by tie-plate 2, the side wheel wheel rim 411 of side wheel 41 links to each other with the output of reductor 3, and side wheel wheel rim 411 links to each other by connector 5 with the breast wheel wheel rim 421 of breast wheel 42.Be equiped with bearing support 6 on the breast wheel wheel rim 421 of breast wheel 42, the bearing support 6 that is equiped with axle 7, two breast wheels 42 by a holder 8 on the rear wheel frame 1 is supported in axle 7 both ends respectively.This structure makes the operation of re-type become more simple: change breast wheel 42 if desired, only need take a holder 8 and connector 5 apart, whole release breast wheel 42 is also changed; Two side wheels 41 about changing if desired, after releasing breast wheel 42, can directly dismantle, and change any one side wheel 41 and do not need to dismantle reductor 3, hydraulic motor 13 and hydraulic oil pipe thereof, so not only save the time but also reduced the possibility that produces new fault, helped improving the reliability of system, the convenience of maintenance.Make again simultaneously the dismounting of trailing wheel and installation become flexibly, simple, can save a large amount of dismounting time, be convenient to realization portion and adorn and continuous productive process, help enhancing productivity.Connector 5 is a spline housing, and bearing support 6 is provided with external splines, and connector 5 and bearing support 6 are connected by spline.Realize the transmission of driving force between two wheel rims, guaranteed that four trailing wheels can both obtain driving moment.On the mounting or dismounting mode, four trailing wheels can be divided into three groups: two breast wheels 42 constitute one group with axle 7, bearing support 6, axle holder 8 etc., and two side wheels 41 constitute two groups with reductor 3, hydraulic motor 13 respectively.About two groups with middle groups connect by connector 5 realize, with the connecting of rear wheel frame 1 by tie-plate 2 realizations.When rear wheel assembly was assembled, three groups can be connected in tie-plate 2 on the rear wheel frame 1 then respectively as the parts assembling, again with about reductor 3 in two groups connect with tie-plate 2; Middle groups puts spline housing on the bearing support 6 of portion dress back at two, push together in the axle holder 8 of rear wheel frame 1 and also use bolt, at last two spline housings is pulled out to the left and right, links to each other with side wheel wheel rim 411.Process is opposite when rear wheel assembly is dismantled.
