Abstract
The invention discloses a hydraulic control system for an accelerator, which comprises an accelerator pedal, an oil inlet pipe, a first cylinder and a second cylinder. The hydraulic control system for the accelerator is characterized by further comprising a spring, the accelerator and a draw bar component, the accelerator pedal is connected with the first cylinder, an oil outlet of the first cylinder is connected with an oil inlet of the second cylinder by the oil inlet pipe, a horizontal fixing seat is arranged on a side surface of the second cylinder, a cylinder rod of the second cylinder is connected with the draw bar component by a connecting plate, one end of the spring is connected with the horizontal fixing seat, the other end of the spring is connected with the connecting plate, the accelerator is disposed at one end of the draw bar component, and the oil inlet pipe is a hose. By the aid of the hydraulic control system for the accelerator, the problem that an accelerator control system in the prior art is connected by a flexible shaft wire, a route of the accelerator control system is long, delay and idle stroke are caused, and the accelerator control system is insensitive in use. The hydraulic control system for the accelerator is free of delay and high in sensitivity by the aid of the characteristic that hydraulic oil cannot be compressed.
Description
Technical field
The invention belongs to technical field of hydraulic, particularly relate to a kind of throttle hydraulic control system.
Background technique
Hydraulics is one of key technology that realizes modernized transmission and control, and countries in the world have given very big attention to the development of hydraulic industry, and extensive use and national economy all departments.Hydraulics has that power-weight ratio is big, and volume is little, and is simple in structure, and frequency response is high, and pressure, flow rate controllability are good, can flexiblely transmit power, are prone to realize advantages such as straight line motion, and are prone to combine with microelectronic, electrical technology the formation automatic control system.But the hydraulic control art also exists simultaneously seepage, maintainability poor, and sensitivity is lower, postpones more high shortcoming.For this reason, must give full play to the advantage of hydraulic control technology, overcome the deficiency, attention and electronic technology combine, constantly the expanding application field.
Summary of the invention
Throttle control system adopts flexible shaft line to connect, exist circuit longer in the existing technology in order to solve; Have and postpone and idle stroke; Use insensitive problem, the invention provides a kind of incompressible characteristic of hydraulic oil of utilizing and realize not having delay, high-sensitive throttle hydraulic control system.
In order to address the above problem, the technological scheme that the present invention taked is:
The throttle hydraulic control system comprises gas pedal, oil inlet pipe, first oil cylinder and second oil cylinder, it is characterized in that: also comprise spring, throttle and rod assembly; Said gas pedal is connected with first oil cylinder; The said first oil cylinder oil outlet is connected through the filler opening of oil inlet pipe with second oil cylinder, is provided with the horizontal fixed seat in the side of second oil cylinder, and the cylinder rod of said second oil cylinder is connected with rod assembly through connecting plate; One end of spring is connected with the horizontal fixed seat; The other end is connected with connecting plate, and an end of rod assembly is provided with throttle, and said oil inlet pipe adopts flexible pipe.
Aforesaid throttle hydraulic control system, it is characterized in that: oil inlet pipe is provided with bleed valve.
Aforesaid throttle hydraulic control system is characterized in that: the side at second oil cylinder is equipped with fixed support, in support bracket fastened arranged outside the horizontal fixed seat is arranged.
Aforesaid throttle hydraulic control system is characterized in that: the said first oil cylinder filler opening is connected with repairing kettle oil outlet through the repairing pipe.
Aforesaid throttle hydraulic control system is characterized in that: the repairing pipe is provided with Fill valve.
The invention has the beneficial effects as follows: throttle hydraulic control system of the present invention utilizes hydraulic pressure as driven medium, adopts two oil cylinder, the mode of intermediate hose; Realize no-idle running, do not had delay, highly sensitive; Effect such as simple to operate is fit to combine with electronic technology, has to cut down the consumption of energy; Raise the efficiency, adapt to the environmental protection demand, improve characteristics such as reliability.
Description of drawings
Fig. 1 is the structural representation of throttle hydraulic control system of the present invention.
Embodiment
Below in conjunction with accompanying drawing the present invention is done further description.
As shown in Figure 1; The throttle hydraulic control system comprises throttle 1, rod assembly 2, fixed support 3, spring 4, second oil cylinder 5, gas pedal 7, first oil cylinder 9 and oil inlet pipe 11, and gas pedal 7 is connected with first oil cylinder 9; First oil cylinder, 9 oil outlets are connected through the filler opening of oil inlet pipe 11 with second oil cylinder 5; In the side of second oil cylinder 5 fixed support 3 is installed, has the cylinder rod of horizontal fixed seat 13, the second oil cylinders 5 to be connected with rod assembly 2 in the arranged outside of fixed support 3 through connecting plate 12; One end of spring 4 is connected with horizontal fixed seat 13; The other end is connected with connecting plate 12, and the lower end of rod assembly 2 is provided with throttle 1, and oil inlet pipe 11 adopts flexible pipe.
First oil cylinder, 9 filler openings are connected with repairing kettle 10 oil outlets through repairing pipe 14, and repairing pipe 14 is provided with Fill valve 8, when first oil cylinder, 9 fluid are not enough, can be through repairing kettle 10 to the required fluid of first oil cylinder, 9 supplies, and convenient follow-up use.
When needs change throttle 1 aperture; At first by the step on the throttle stroke of pedal 7 control first oil cylinder 9 of driver; Hydraulic oil passes to second oil cylinder 5 by oil inlet pipe 11 under the promotion of first oil cylinder 9; Second oil cylinder 5 overcomes spring 4 resistances under the promotion of hydraulic coupling, promote connecting plate 12 drive rod assemblies 2 through second oil cylinder, 5 cylinder rods and move, and while throttle 1 is movement therewith also; Realize the increase of throttle 1 aperture, the length that the size of throttle 1 aperture is directly stretched out along with second oil cylinder, 5 cylinder rod bars and changing.
In like manner, when unclamping the power that imposes on gas pedal 7, under the effect of the restoring force of spring 4, the hydraulic oil reverse flow realizes reducing of throttle 1 aperture.In addition after assembling is accomplished, the continuous several times pedal 7 of stepping on the throttle unclamps again, the bleed valve 6 of outwarding winding then, and the air in pipeline and the oil cylinder gets final product emptying, and the whole system using effect is better.The Fill valve 8 of outwarding winding simultaneously, repairing kettle 10 to the required fluid of first oil cylinder, 9 automatic supplies, make things convenient for the follow-up control of throttle hydraulic control system to use through repairing pipe 14
More than show and described basic principle of the present invention, major character and advantage.The technician of the industry should understand; The present invention is not restricted to the described embodiments; That describes in the foregoing description and the specification just explains principle of the present invention; Under the prerequisite that does not break away from spirit and scope of the invention, the present invention also has various changes and modifications, and these variations and improvement all fall in the scope of the invention that requires protection.The present invention requires protection domain to be defined by appending claims and equivalent thereof.
