Description
One, technical field
The present invention relates to a kind of environmental sanitation mechanical equipment, be specifically related to small-sized full hydraulic drive road broom chassis.
Two, background technology
The mechanization of major urban arterial highway cleaning has been realized in the most domestic city basically at present; But account for the half the lane, street of city sweep-out pattern nearly, go slowly, park, square and sidewalk still lean on manpower to use big broom completion cleaning work; To realize the mechanization cleaning in these zones, require then that the cleaning machine structure is small and exquisite, flexible operation, convenience.Small-sized full hydraulic drive road broom has appearred at present, these small-sized road broom compact conformations, and flexible operation, light can satisfy the requirement of above-mentioned cleaning machine.But there is following defective in existing small-sized full hydraulic drive road broom: the one, generally adopt rubber tire and bump rubber damping, and cause that the complete machine damping effect is bad, travelling comfort is poor, the defective of operator's easy fatigue; The 2nd, existing small-sized full hydraulic drive road broom is owing to receiving the restriction of operation property, no matter be operation or transition, the rotating speed of driving engine all is to be fixed on work under the high rotating speed, certainly will cause the increase that oil consumption is high, noise is big and discharge like this.
Three, summary of the invention
The purpose of this invention is to provide a kind of small-sized full hydraulic drive road broom chassis, make that the oil consumption of road broom complete machine is low, noise and discharging is little, good damping effect, ride comfort, to solve the defective of existing small-sized road broom.
For realizing above purpose, the small-sized full hydraulic drive road broom of the present invention chassis comprises operator's compartment, bearing circle, seat, electric-controlled box, propons, vehicle frame, gear type pump, Variable plunger pump, engine assembly, brake pedal unit, E-gas, hydraulic steering gear, front-wheel, steering hardware, hydraulic reservoir, diesel fuel tanks, coil spring liquid damper, back wheel-side motor and trailing wheel; Respectively establish two before and after the said coil spring liquid damper; Front coil spring liquid damper one end connects vehicle frame; The other end connects propons, and is engaged on the vehicle frame through forward mounting swing arm, forward mounting ball end and forward mounting otic placode, constitutes the suspension of torsion beam independent; Rear coil springs liquid damper one end connects vehicle frame, and the other end connects trailing wheel limit motor fixing base, and is engaged on the vehicle frame through rear overhang earphone plate, back suspension arms and back suspension pin, constitutes independent suspension; Said Variable plunger pump is through electric proportional control, and said electric-controlled box has been set up the module of control engine speed and controllable capacity pump apportioning valve, through electronic intelligence control, realizes two kinds of patterns of operation and transition.
The suspension of torsion beam independent is adopted on the small-sized full hydraulic drive road broom chassis of said structure propons on the one hand; Back axle adopts independent suspension; Adopt custom-designed high bearing capacity coil spring liquid damper and good suspension adjustment simultaneously; And reduce unsprung weight, and simple in structure, easy for installation, improved small-sized road broom complete machine damping effect and travelling comfort greatly; The monomotor configuration is adopted on this small-sized full hydraulic drive road broom chassis on the other hand, has two kinds of mode of operations of operation and transition, compares with the existing road pickup sweeper and can reduce road broom operation oil consumption; Reduce the operation discharging; Structure is small and exquisite, and manoevreability is good, improves space availability ratio simultaneously.This structural chassis is swept the road equipment through replacing and can be realized cleaning work is carried out on footway, park, square, perhaps can clean and snow removing unpowered vehicle roads such as footways through after the simple refit.Can shuttle back and forth easily with footway, park, square carry out cleaning work.

Fig. 1 is that the small-sized full hydraulic drive road broom chassis A-A of the present invention is to scheme drawing.
Fig. 2 is the small-sized full hydraulic drive road broom of a present invention chassis schematic top plan view.
Five, embodiment
Through the accompanying drawing and the specific embodiment the present invention is done further explain below.
Like Fig. 1～shown in Figure 2, the small-sized full hydraulic drive road broom of the present invention chassis comprises operator's compartment 1, bearing circle 2, seat 3, electric-controlled box 4, propons 5, vehicle frame 6, gear type pump 7, Variable plunger pump 8, engine assembly 9, brake pedal unit 10, E-gas 11, hydraulic steering gear 12, front-wheel 13, steering hardware 14, hydraulic reservoir 15, diesel fuel tanks 16, coil spring liquid damper 17, right back wheel-side motor 18 and trailing wheel 19; Said coil spring liquid damper 17 front and back are respectively established two; Front coil spring liquid damper one end connects vehicle frame 6; The other end connects propons 5, and is engaged on the vehicle frame through forward mounting swing arm, forward mounting ball end and forward mounting otic placode, constitutes the suspension of torsion beam independent; Rear coil springs liquid damper one end connects vehicle frame 6, and the other end connects trailing wheel limit motor fixing base, is engaged on the vehicle frame 6 through rear overhang earphone plate, back suspension arms and back suspension pin simultaneously, constitutes independent suspension; Said Variable plunger pump 8 is through electric proportional control, and said electric-controlled box 4 has been set up the module of control engine speed and controllable capacity pump apportioning valve, through electronic intelligence control, realizes two kinds of patterns of operation and transition.
Operator's compartment 1 connects through damping rubber block and vehicle frame 6; Also be to adopt elastic coupling between driving engine 9 and the vehicle frame 6, plunger pump 8 adopts elastic coupling to connect with the flywheel mouth of driving engine 9, and gear type pump 7 is serially connected in the rear end of plunger pump 8; Adopt the suspension of torsion beam type independent to connect between propons 5 and the vehicle frame 6; All adopt independent suspension to connect after left and right two between wheel-side motor and the vehicle frame 6, diesel fuel tanks 16 and hydraulic reservoir 15 are separately fixed at the left and right sides of vehicle frame, two hydraulic fluid ports of plunger pump through hydraulic tubing respectively with the hydraulic fluid port connect in parallel of left and right two-wheeled limit motor; Realize takeoff output; And the oil outlet of gear type pump and deflector 12 connect, and for steering hardware provides pressure oil, realize fluid-link steering.
