Control fuel tap, reduces oil pump capacity by control fuel tap and resistant pump can be made to produce resistance, and the resistance produced by resistant pump makes vehicle row
The resistance sailed increases to reduce the speed that vehicle travels, and the opening and closing of control fuel tap is controlled by control system by electronic tie rod,
Current speed is detected by vehicle speed detector, progressively closes off when speed reaches the peak time control fuel tap of setting value, resistance
The resistance increase of pump makes vehicle deceleration, is gradually opened when speed drops to the minimum point time control fuel tap of setting value, the resistance of resistant pump
Power reduces makes vehicle rely on inertia to accelerate to reach the speed set, and vehicle can closing control system when flat pavement running or upward slope
System, now resistant pump is in idling conditions, will not consume the kinetic energy of vehicle.
Detailed description of the invention
Resistance system, by resistant pump, oil inlet pipe, inlet valve, flowline, controls fuel tap, electronic tie rod, radiator and hydraulic oil
Case forms, and its operation principle is to make resistant pump produce resistance, the resistance produced by resistant pump by the opening and closing of control control fuel tap
The speed travelling vehicle is controlled, and resistant pump needs to be divided into large-scale blade according to resistance and the rotating speed of big dilly
Pump, gear pump and piston pump etc., (motorbus is fast because of its travel speed, can use large-scale vane pump, gear pump etc., load-carrying
Lorry travel speed is slow, and the slow-speed of revolution such as gear pump and piston pump can be used to appoint the pump housing that can reach preferable performance), its act as by
Hydraulic oil is drawn through pump body compression from oil inlet pipe and discharges from flowline, and one end universal joint of the pump housing is connected to vehicle speed variation
On the outfan of case rotor, other end universal joint connects the power transmission shaft of back axle, and the pump housing is fixed on vehicle frame by fixed mount
On, resistant pump is provided with oil inlet pipe and flowline, and oil inlet pipe is arranged on the lower end of resistant pump, and inlet valve is arranged on oil inlet pipe,
Its oil inlet passage acting as being turned on and off resistant pump, when resistant pump is not actuated, inlet valve is closed, and flowline is pacified
Being contained in the upper end of resistant pump, control fuel tap is arranged on flowline, its size acting as controlling oil pump capacity, and electronic tie rod is arranged on
In order to control the action of fuel tap on control fuel tap, release time control fuel tap when electronic tie rod and close, when electronic tie rod draws in time control oil
Valve is opened, and pressure valve is arranged on the front end of flowline upper fuel-controlling valve, and the oil exit pipe of pressure valve connects the oil pipe of control fuel tap rear end, pressure
When power is normal, hydraulic oil flows to control fuel tap through pressure valve, and when in flowline, the pressure of hydraulic oil exceedes setting value, pressure valve is opened
Opening, in now hydraulic oil is directly discharged into the oil pipe of control fuel tap rear end, the rear end of control fuel tap oil pipe connects radiator with to hydraulic pressure
The heat that oil produces cools down, and the flowline of radiator connects hydraulic oil container, and hydraulic oil container connects inlet valve by oil pipe.
Operation control system is made up of controller and manual draw bar, and its operation principle is the power supply sent by control system
The resistance of resistant pump is controlled by signal to start electronic tie rod, and controller is microcomputerized control mechanism, and display window is provided with
The load button being controlled speed, the speed that vehicle is travelled by vehicle speed detector detects, and the data that will detect
Real-time Transmission is to controller, and during work, controller sends power supply signal to control electronic tie rod after being analyzed current speed
Push pull maneuver, need during system start-up manually to controller input, speed to be carried out the peak and minimum controlled, be now
Inlet valve is opened by system, and in hydraulic oil intake resistance pump, the power transmission shaft of vehicle drives resistant pump to rotate and sucked by hydraulic oil, pressure
Contracting, is entered radiator by flowline through control fuel tap, and when speed reaches the peak set, system sends signal to electronic tie rod
Power supply makes control fuel tap progressively close off, and when speed reaches the minimum point set, system sends reverse electrical source letter to electronic tie rod again
Number, control fuel tap is gradually opened, and when drag devices is not actuated, the inlet valve on oil inlet pipe is closed, the most a small amount of liquid
Force feed enters the pump housing and is lubricated it, and resistant pump is in idling conditions, will not consume the kinetic energy of vehicle.
Manual draw bar is arranged on the place convenient to operate of driver's cabin, is directly connected to inlet valve and control fuel tap by cable wire, when not
Needing to get final product direct pull manual draw bar during system cruise control, when being drawn to certain angle, inlet valve is opened, when gradually pulling
Control fuel tap progressively closes off, and manual draw bar gradually return time control fuel tap is gradually opened, and now can be manually operated manual draw bar
Being controlled resistant pump, when manual draw bar pull-up, operation control system is automatically switched off under the effect of travel switch.
To the required peak controlling car speed of control system input and minimum during system work, now speed is visited
Surveying device to detect current speed in real time, when speed reaches the peak of setting value, system start-up electronic tie rod gradually will
Control fuel tap cuts out, and the oil-out of flowline reduces, and now the hydraulic fluid pressure in flowline and resistant pump increases, and hydraulic oil is to resistance
The rotating part of power pump imposes the resistance increase that reverse active force makes resistant pump rotate, and the resistance of resistant pump is straight by power transmission shaft
Switching through and turn to the resistance that vehicle advances, after the resistance of vehicle increases, speed is gradually reduced, and treats that speed drops to the minimum of setting value
During point, control fuel tap is gradually opened by system start-up electronic tie rod, and now the oil pump capacity of flowline increases, and the pressure of resistant pump reduces
So that resistance reduces, the resistance of vehicle relies on the inertia force of descending to make speed increase after reducing, and treats that speed increases to setting value
During peak, system repeats above action, as run into urgent downhill driving person have little time operation control system time, driver is i.e.
Can direct pull manual draw bar, now inlet valve is opened, control fuel tap progressively close off under the dynamics pulled, continue when resistance is inadequate
The continuous angle increasing pull-up, the return manual draw bar suitable when resistance is excessive, now speed can be carried out Non-follow control, by
Working media in resistant pump is hydraulic oil, is to make equipment produce resistance by compression hydraulic oil, does not has brake block during work
The rigid friction of formula, during work hydraulic oil produce heat discharged in time by radiator, therefore resistant pump can work long hours and
Do not affect its performance.
