The special-purpose self-propelled frame in above-mentioned airport, vehicle frame is the integral solder vehicle frame.
The special-purpose self-propelled frame in above-mentioned airport, it also comprises by gear type pump, deflector, the steering swivel system that turns to oil cylinder, steeraxle to form, the input shaft of gear type pump is connected with the input shaft of controllable capacity pump and obtains power, hydraulic oil in the fuel tank is delivered to deflector, deflector is transported to hydraulic oil and turns to oil cylinder, turns to oil cylinder to link to each other with steeraxle.
The special-purpose self-propelled frame in above-mentioned airport, thus it comprises by gathering the electric system of engine speed control variable pump capacity.
The special-purpose self-propelled frame in above-mentioned airport, it also comprises operator's compartment, described operator's compartment is single operator's compartment.
The beneficial effects of the utility model:
1. compact conformation can be different airport special-use vehicles different arrangement forms is provided, thereby the vehicle that requires for differing heights provides different arrangement forms;
2. by the deceleration increment, the may command maximum speed is 25 kilometer per hours, thereby the propulsive effort of vehicle maximum is provided, and reduces vehicle oil consumption and pollution;
3. use the full hydraulic drive pattern, realize the vehicle stepless change;
4. special operator's compartment is vehicle specific function design arrangement, and the maximized easy to operate demand that satisfies the staff realizes human oriented design.
Description of drawings
Fig. 1 is the front view on the utility model chassis.
Fig. 2 is the birds-eye view (scheme drawing) on the utility model chassis.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further specified.
As shown in the figure, self-propelled frame described in the utility model comprises vehicle frame, is arranged on operator's compartment, drive system, driving system, brake system, steering swivel system, driving system, electric system, hydraulic efficiency pressure system on the vehicle frame, and each system is connected with pipeline by bolt.Main parts size has deflector 1, operator's compartment 2, and brake system 3, shock mitigation system 4, driving engine 5, vehicle frame 6, drive axle 7, transmission shaft 8, reductor 9, fuel tank 10, fixed displacement motor 11, gear type pump 12, controllable capacity pump 13 turns to oil cylinder 14, steeraxle 15, hydraulic reservoir 16 etc.
The transmission of power transfers to controllable capacity pump by the coupler that is connected with driving engine, controllable capacity pump reaches fixed displacement motor with the hydraulic oil in the hydraulic reservoir, the power of fixed displacement motor output is delivered to drive axle by transmission shaft after increasing square by the retarder deceleration, thus powered vehicle.Specifically, power driven provides power for driving engine 5 obtains the fuel oil running from fuel tank 10, through elastic coupling moment of torsion is reached controllable capacity pump 13, the hydraulic flow that the signal adjustment that controllable capacity pump 13 provides according to electric system is exported, system transmissions is to fixed displacement motor 11 by the road, fixed displacement motor 11 is connected with reductor 9 usefulness splines, and the moment of torsion of fixed displacement motor 11 outputs is exported to the main reduction gear of drive axle 7 again by transmission shaft 8 after reductor 9 decelerations increase square, thereby powered vehicle is advanced.By rational calculating, reach suitable reduction ratio after the rotating speed of driving engine output slowed down by reductor 9 and drive axle 7, thereby the control vehicle maximum travelling speed is 25 kilometer per hours.
The vacuum servo that brake system 3 provides by driving engine realizes the braking to drive axle 7 and steeraxle 15 wheels.
Shock mitigation system 4 provides steadily comfortable running environment by the damping modes of steel spring and the combination of damping shock absorption device for vehicle '.
Described steering swivel system provides power by turning to oil cylinder, deflector and gear type pump etc. to form by gear type pump, and deflector control turns to the action of oil cylinder, thereby realizes front-wheel steering.Gear type pump 12 obtains power by being connected with controllable capacity pump 13, and to deflector 1, the rotation of deflector 1 direction of passage dish variation is transported to hydraulic oil and turns to oil cylinder 14 with the hydraulic oil pump in the hydraulic reservoir 16, thereby drives turning to of steeraxle 15.
When work in this utility model chassis, thereby gather engine speed system control variable capacity of pump, so just can realize the travel direction commutation function of stepless change and vehicle by electric system.Car travel mode can be switched to mode of operation by the change-over switch pattern simultaneously, like this, the power that gear type pump 12 is provided provides power with regard to can be the hydraulic ram of adorning on the vehicle, thereby realizes the special function of vehicle.In order to be satisfied with some special stipulation and the demand of airport to ground support equipment, airport of the present utility model chassis special, for last dress part is reserved power, this chassis can provide the operation power of walking power and isolated plant for various airfield vehicles as the standard form chassis.
Its operator's compartment for the self-control single operator's compartment, be furnished with in it the driving instrument desk, on adorn function control desk, car load electric control box, seat etc.
Vehicle frame is the integral solder vehicle frame, is mainly truss structure, and is stressed reasonable.
