Abstract
The utility model relates to a driving apparatus for pneumatic rollers, and is characterized in that a supporting frame (7) is fixed on the frame (1) of the roller, wherein a flange disk (6) is arranged on the supporting frame (7), wherein a reductor (4) connected with a hydraulic motor (5) is arranged on the flange disk (6), and the revolving end of the reductor (4) is connected directly with a driving wheel (3). The supporting frame (7) can be arranged at the middle of the driving wheel (3) or be arranged at the two sides of the driving wheel (3). The utility model has the advantages of simple and smart structure, easy manufacture, low cost, good practicability, convenient maintenance and long service life. The utility model represents an important tendency of heavy-duty fully hydraulic driving pneumatic roller in the construction machinery field.
Description
Technical field:
The utility model relates to the engineering construction mechanical field, is specifically related to the improvement to the rubber tyred roller drive unit.
Background technology:
Machine driving exists in the existing rubber-tyred roller impact when starting and stopping, and needs the complicated gear transferring power of a cover; But machinery and fluid power combined type transmission stepless speed regulation, but high efficient area is narrower, and rubber-tyred roller compacting effective speed scope is diminished.Present employed full hydraulic drive rubber-tyred roller, its driving device structure is that the hydraulic oil of volume adjustable hydraulic pump output directly enters the motor of two parallel connections, motor is installed on the homemade gear-box, gear-box is installed on the afer bay of road roller with bolt, the motor driven wheel, the axle of the step-by-step variable gear tire on the drive wheels in the gear-box is again by the jackshaft tire on the drive wheels.Owing to reasons such as this complex structure, repairing inconveniences, practical effect is not fine.
The utility model content:
Technical problem to be solved in the utility model is the defective that overcomes present prior art, provides a kind of structure design simple, easy to maintenance rubber-tyred roller drive unit.
Technical problem of the present utility model is to realize by following technical scheme.It is characterized in that it is to fix a bearing support on the road roller frame, this bearing support is provided with flange, reductor be loaded on this flange after hydraulic motor connects, reductor round end and driving wheel directly link.Described bearing support can be positioned at the driving wheel centre position, also can be arranged on the driving wheel both sides.
The utility model structure design is simple, ingenious, and is easy to manufacture, and cost is low, and practicality is good, and is easy to maintenance, and long service life is an important directions of heavy full hydraulic drive rubber-tyred roller type of drive development.
Description of drawings:
Fig. 1 is the utility model embodiment one structural representation;
Fig. 2 is the utility model embodiment two structural representations.
Among the figure:
The 1-frame; The 2-wheel rim; The 3-driving wheel;
The 4-reductor; The 5-hydraulic motor; The 6-flange;
The 7-bearing support.
The specific embodiment:
The utility model is to arrange the improvement that the problem of existence is carried out at driving device structure in the existing full hydraulic drive rubber-tyred roller, and Fig. 1 and Fig. 2 have showed two Application Examples of the utility model.
As shown in the figure, it is to fix a bearing support 7 on road roller frame 1, this bearing support 7 is provided with high strength flange 6, directly pack into after hydraulic motor 5 and reductor 4 are integrated in the wheel rim 2 of driving wheel 3 tires, reductor 4 fixed ends link to each other with bearing support 7 by flange 6, round end and driving wheel 3 spokes directly link, and two driving wheels 3 constitute one group, and the spoke of tire is connected with reductor 4 with bolt face-to-face.Hydraulic oil by volume adjustable hydraulic pump output directly enters the hydraulic motor 5 that is installed in two parallel connections on the reductor 4, hydraulic motor 5 drive speed reducer 4, and the direct again tire on the drive wheels of reductor 4 rotates driving wheel 3.Change the output flow of pump, just can change the travel speed of road roller; Change the POF direction, just can change the travel direction of road roller.
The utility model bearing support 7 can be provided with as required, both can be arranged on by structure shown in Figure 1 in the middle of the whole driving wheel 3, also can be arranged on driving wheel 3 both sides by structure shown in Figure 2.
The utility model can be used for the type of drive that hydraulic motor is a low speed high torque hydraulic motor, both can be used for the rubber-tyred roller of " preceding 5 backs 4 " tire construction, also can be used for the rubber-tyred roller of " preceding 5 backs 6 " tire construction.
Claims (3)
