Abstract
The utility model discloses a compact double-shaft electro-hydraulic shifting manipulation system, and belongs to a shifting manipulation system of engineering machinery. The manipulation system comprises a manipulation valve, a locating pin, a connecting shaft, a fixing base and an execution system, wherein the manipulation valve and the execution system are respectively arranged on two sides of the fixing base and connected through the connecting shaft, and the locating pin is connected with the connecting shaft. The double-shaft electro-hydraulic shifting manipulation system changes the position of a valve rod of a manipulation valve of a traditional manipulation system, and enables the manipulation valve to rotate 180 degrees and the overall structure of the manipulation valve to be compact. A motor fixing base enables installation and disassembly of the system to be convenient. The improved electro-hydraulic shifting manipulation system is small in overall size, high in reliability, capable of sufficiently using space in an existing host machine, and convenient to install and debug.
Description
Technical field
The utility model relates to a kind of gearshift control system of engineering machinery, particularly a kind of compact type double-shaft type electro-hydraulic gear-shifting control system.
Background technique
Extensively adopt torque converter on engineering machinery and the various vehicle.It is comprised of fluid torque converter and power-shift transmission.Mechanical-hydraulic gearshift, two kinds of control systems of electrichydraulic control gearshift are adopted in the shift control control of torque converter mostly.The mechanical-hydraulic shift control system is by use mechanical linkage or the direct push-and-pull hydraulic speed-changing of flexible axle control valve valve rod, thus the break-make of control hydrovalve master control oil circuit, to realize shift control.It exist to handle the problems such as resistance is large, labor intensity was large when gearshift was frequent, and connecting rod is spatial structure, brings difficulty for design, layout and the installation adjustment of system host.The electrichydraulic control shifting control system adopts gear selector, controls leading hydraulic system by gear selector, and the break-make of realization hydrovalve main control oil circuit realizes commutation and the gear shift operation of vehicle.It has overcome all drawbacks of mechanical-hydraulic gearshift, it is the developing direction of current engineering machinery driving control system, but it also has deficiency: poor reliability, rate of fault such as parts such as contact-type gear selector, solenoid valves are high, and system's manufacture cost is high, maintenance high in cost of production problem.
Although the non-leading type double-shaft type electro-hydraulic gear-shifting control system that exists at present has easy and simple to handle, the advantages such as manufacture cost is moderate, substantially problems such as can solving mechanical control system mounting point restriction, need often to regulate the push-and-pull stroke, easily out of supply, inconvenient operation, labor intensity be large, but for some particular manipulation valve arrangement, because hosting space is little, system installs, debugging is greatly affected.
The model utility content
The purpose of this utility model is that a kind of compact type double-shaft type electro-hydraulic gear-shifting control system will be provided, and solves the problems such as existing control system mounting point is limited, inconvenient operation.
The purpose of this utility model is achieved in that this gearshift control system comprises control valve, locating stud, coupling shaft, fixed base and executive system, control valve and executive system are installed in respectively the fixed base both sides, control valve is connected coupling shaft with executive system and connects, and is connected with locating stud at coupling shaft.
Beneficial effect owing to having adopted such scheme, compact type double-shaft type electro-hydraulic gear-shifting control system to change the position of traditional control system control valve valve rod, makes it rotate 180 °, so that overall structure is compacter; The design of fixed base, make system installation, the dismounting convenient; And fixed base employing cast steel or steel physical treatment, substitute original welded structure, improved the integral rigidity of system.Electric liquid gearshift control system overall dimensions after this improvement is little, and reliability is high, can take full advantage of existing hosting space, can easily install, debug.Solve the problems such as existing control system mounting point is limited, inconvenient operation, reached the purpose of this utility model.
Advantage: control system is simple in structure, and overall dimensions is little, has reduced the requirement to the installing space of main frame.Adopt novel valve stem, accurate positioning, installation, maintenance is convenient, low cost of manufacture.The fixed base bearing capacity is further strengthened, and service behaviour is more reliable.Efficiently solve the interference problem of itself and control valve, and so that the installing/dismounting of whole system is more convenient.
