Description
Technical field
The utility model is related to a kind of hybrid power automatic transmission flow coupling control system testing stand configuration, is a kind of
The flow coupling control system test-bed configuration of new automatic transmission, belongs to the technical field of automatic transmission design.
Background technology
Hybrid power automatic transmission technology is one of current energy-saving automobile cutting edge technology, and the power unit of hydraulic system is
The critical component of hydraulic automatic transmission product, original automatic transmission mechanical pump is driven by power motor, system output stream amount
Influenceed larger by driving cycle, mechanical pump fan-out capability may cause the shake of working connection pressure, Hydraulic Elements response when not enough when
Between long, even system heat load characteristic variations cause the phenomenons such as element scaling loss.To compensate the underfed of hydraulic system, system is new
Increase auxiliary pump unit, the power unit of hydraulic system is constituted with original mechanical pump.Ensureing the premise of power performance demand
Under, mechanical pump is cooperated with auxiliary electric pump, carry out the optimum organization of various flow rate coupling, form different working connections and build
Die pressing type realizes the output on demand of flow to adapt to the driving cycle demand of consecutive variations.
The content of the invention
The purpose of this utility model is to provide a kind of hybrid power automatic transmission flow coupling control system testing stand
Configuration, its dynamic characteristic coupled by sensor detecting system flow adjusts medium temperature by environmental cabinet, carries out dry oil immersion electricity
Machine thermal balance research.
What the technical solution of the utility model was realized in：A kind of hybrid power automatic transmission flow coupling control system
System testing stand configuration, including environmental cabinet, mechanical pump, electrodynamic pump, valve body assembly, pressure sensor, cleaner, check valve, overflow
Valve, variable throttle valve；It is characterized in that：What mechanical pump and electrodynamic pump were exported is fluidly coupled to defeated after being filtered afterwards through cleaner all the way
Enter hydraulic valve, install processing oil return oil duct in variable throttle valve adjustment outlet load, environmental cabinet additional in system outlet, pass through oil return
Hole makes the medium back flow with temperature property and impacts electronic pump case.
While core content of the present utility model is to realize the independent control of mechanical revolution speed and electronic revolution speed
Realize the coupling of double pump output flow；By regulation valve body load and environmental cabinet temperature, double pump coupling oil sources is truly reappeared
System actual use operating mode, effectively support is provided for proposition and the checking of control strategy and method.While environmental cabinet temperature adjustment
Impact and design with oil return, the actual use operating mode of formula motor can be dipped dry with simulation oil, and carry out the thermal balance characteristics analysis of system.
Brief description of the drawings
Fig. 1 is the utility model schematic diagram.
Embodiment
The utility model is further described below in conjunction with the accompanying drawings：A kind of hybrid power automatic transmission flow coupling
Control system testing stand configuration, including environmental cabinet 1, valve body assembly 2, overflow valve 3, mechanical pump 4, check valve 5, cleaner 6, pressure
Sensor 7, variable throttle valve 8, electrodynamic pump 9；It is characterized in that：After what mechanical pump 4 and electrodynamic pump 9 were exported is fluidly coupled to all the way
Input hydraulic pressure valve body after the filtered filtering of device 6, installs additional in system outlet and adds in the adjustment of variable throttle valve 8 outlet load, environmental cabinet 1
Work oil return oil duct, makes the medium back flow with temperature property by spill port and impacts electronic pump case.
It is immersed in as shown in figure 1, adding hydraulic oil in environmental cabinet 1 to scale, electrodynamic pump 9 is set in hydraulic oil, each liquid
Pressure electromagnetic valve and sensor integration are arranged on valve body assembly 2, and cleaner 6 is used to filter the impurity in fluid, it is ensured that system is clear
Cleanliness.Mechanical pump 4 export firm discharge, by adjust the aperture of variable throttle valve 8 control working connection pressure, working connection pressure by
Sensor 7 is monitored.When system pressure exceedes 3 setting value of overflow valve, overflow valve 3 opens off-load, it is ensured that the normal work of system
Make.The outlet of electrodynamic pump 9 installs check valve 5 additional, and mechanical pump discharge is reversely ended, and protection electrodynamic pump is changed a job condition without hair.Regulating system goes out
Mouth pressure, starts electrodynamic pump 9 under different load conditions, carries out flow coupling and the research of motor thermic load characteristic.
