Abstract
The invention discloses a hydraulic driving device of a road sweeper, which comprises an engine, a hydraulic pump, a control valve, a hydraulic motor, a universal driving device, a hydraulic oil tank, a gear transmission and a driving bridge, wherein the engine is fixed on a chassis of the road sweeper; the hydraulic pump is directly connected with the engine; the hydraulic motor is fixed on the frame of the road sweeper, and positioned on the upper part of the driving bridge; the hydraulic pump, the control valve, the hydraulic motor and the hydraulic oil tank are respectively connected through hydraulic pipes to form a hydraulic system; the power output end of the hydraulic motor is connected with one end of the universal driving device, and the other end of the universal driving device is connected with the input end of the gear transmission; and the output end of the gear transmission is connected with the driving bridge. By using the hydraulic pipelines to replace the traditional driving mechanism, the invention effectively saves space, has good load distribution, and can reasonably and flexibly install various devices to satisfy various function requirements of the road sweeper.
Description
Technical field
The present invention relates generally to a kind of automotive proplsion, refers in particular to a kind of actuating device of road sweeper.
Background technology
More and more universal along with environmental sanitation mechanization, a lot of big and medium-sized cities have gradually adopted road sweeper to replace broom.Present road sweeper generally will satisfy the cleaning road and prevent the function of secondary dirt contamination, and some also has the function of watering concurrently.The diverse in function of road sweeper causes automobile to arrange that difficulty increases, and vehicle structure is also complicated more simultaneously.
Traditional automobile driving system has mainly comprised driving engine, power-transfer clutch, change-speed box, universal driving device, transmission shaft, retarder, diff and drive axle etc.But for some baroque automobile, particularly for multi-functional road sweeper, traditional drive system can influence the layout of its equipment.Thus, but the actuating device of a kind of flexible arrangement of needs, and when guaranteeing automobile energy cruising, the structural arrangement of As soon as possible Promising Policy all-purpose road pickup sweeper needs.
Summary of the invention
The fluid pressure drive device that the purpose of this invention is to provide a kind of road sweeper, this device flexible arrangement is convenient, distribution of axle load is good, can effectively solve the drive system and the various structural arrangement problem of road sweeper.
Technical scheme of the present invention is such: the fluid pressure drive device of road sweeper comprises driving engine, Hydraulic Pump, control cock, HM Hydraulic Motor, universal driving device, hydraulic reservoir, gear case and drive axle; Above-mentioned driving engine is fixed on the chassis of road sweeper, above-mentioned Hydraulic Pump and above-mentioned driving engine direct connection, and above-mentioned HM Hydraulic Motor is fixed on the position that is positioned at above-mentioned drive axle top on the vehicle frame of road sweeper; Be in turn connected to form a hydraulic efficiency pressure system by hydraulic pipe between above-mentioned Hydraulic Pump, above-mentioned control cock, above-mentioned HM Hydraulic Motor and the above-mentioned hydraulic reservoir; The clutch end of above-mentioned HM Hydraulic Motor connects an end of above-mentioned universal driving device, and the other end of above-mentioned universal driving device connects the input end of said gear case, and the mouth of said gear case connects above-mentioned drive axle.
Be connected with radiator by hydraulic pipe between above-mentioned HM Hydraulic Motor and the above-mentioned hydraulic reservoir.
After adopting such scheme, the fluid pressure drive device of road sweeper of the present invention is during work, the power of the generation of driving engine is input in the Hydraulic Pump, passes to HM Hydraulic Motor by hydraulic pipe again, passes to gear case through universal driving device again, reach drive axle at last, thereby drive whole road sweeper.By control, can realize the forward and reverse of HM Hydraulic Motor, thereby can realize advancing and retreat of automobile control cock.
Compared with prior art, the invention has the advantages that:
1, the fluid pressure drive device of road sweeper of the present invention replaces traditional transmission device by hydraulic tubing, and actv. has been saved the space, and various devices can more rationally be installed flexibly, to satisfy every functional requirement of road sweeper.
2, the fluid pressure drive device of road sweeper of the present invention, compact conformation, distribution of axle load is good, engine radiating is good.
Description of drawings
Fig. 1 is an overall structure scheme drawing of the present invention;
Fig. 2 is the fundamental diagram of hydraulic efficiency pressure system among the present invention.
The specific embodiment
Below with reference to the drawings and specific embodiments the present invention is described in further details.
As shown in Figure 1, 2, the fluid pressure drive device of road sweeper of the present invention comprises driving engine 1, Hydraulic Pump 2, control cock 3, HM Hydraulic Motor 4, radiator 5, hydraulic reservoir 6, universal driving device 7, gear case 8 and drive axle 9.
During work, the power of the generation of driving engine 1 is input in the Hydraulic Pump 2, pass to HM Hydraulic Motor 4 by hydraulic pipe 10 again, HM Hydraulic Motor 4 passes to gear case 8 by universal driving device 7 with power, gear case 8 changes the direction of transfer of power, and the function with speedup of can realizing slowing down, power is passed in the drive axle 10 by gear case 8 at last, thereby drives whole road sweeper.By control, can realize the forward and reverse of HM Hydraulic Motor 4, thereby can realize advancing and retreat of automobile control cock 3.
