Embodiment
Provide specific embodiment below in conjunction with accompanying drawing, further specify the utility model and how to realize.
As shown in Figure 1, wheel box test board of the present utility model, include test board base 101, the upper surface of test board base 101 is provided with base slide rail 105, be provided with master console 102 and by the driving mechanism 103 of master console 102 controls at a side of test board base 101, described test board base 101 is provided with the gear-box bracket 106 that can move and be used to support wheel box 107 along base slide rail 105, described master console 102 is positioned at a side of test board base 101, with the gear-box bracket 106 corresponding power input bindiny mechanisms 104 that are used to be connected wheel box 107 that are provided with, described power is imported bindiny mechanism 104 and is driven by driving mechanism 103.
Described master console 102 includes: center-controlling computer and the control panel 111 that links to each other with center-controlling computer and be used for input control signal and show testing result.
Described driving mechanism 103 includes: the fluid power system 108 and the main motor 109 that are used to drive wheel box 107 by master console 102 controls.Described driving mechanism 103 also includes cooling system 110.
Hydraulic system is the main power system of wheel box test board.Drive main motor power input 100kW, the closed-circuit system that adopts main motor-driven variable output pump and variable displacement motor to form can realize the 0-3500rpm stepless change.As shown in Figure 3, this hydraulic system mainly is made up of with relevant auxiliary element main motor, manual servo variable displacement pump, pressure servo variable displacement motor.
As shown in Figure 2, described power is imported bindiny mechanism 104 and is included: main Connection Block 126, be bolted to connection the joint flange 125 on the port that is positioned at master console 102 sides of main Connection Block 126, rolling bearing units 124 have been bolted to connection in the center pit of described joint flange 125, described main Connection Block 126 is positioned on the side of master console 102 1 sides and is set with bearing seat 122, the hole connection of described rolling bearing units 124 and bearing seat 122 also is provided with spline housing 121 in the hole, described spline housing 121 is positioned at that an end of main Connection Block 126 inboards penetrates is provided with splined shaft 127, be bolted to connection axial location plate 130 and the flexible disc 129 that is used for fixing wheel box 107 on the axle sleeve 128 of splined shaft 127, that end that described spline housing 121 is arranged in master console 102 links to each other with the splined shaft of the pressure servo variable displacement motor 14 of fluid power system 108, the splined shaft that is the oil motor 14 among Fig. 3 is inserted in the spline housing 121, in order to drive the rotation of splined shaft 127, rotate thereby drive wheel box 107 by flexible disc 129.
Wheel box test board of the present utility model is because the closed-circuit system that adopts variable output pump-variable displacement motor to form makes the motor output speed can realize stepless change (0～3500rev/min) in the larger context.The enclosed kinematic train has guaranteed the energy-saving run of system and has reduced volume of fuel tank, and need not use refrigeratory (refrigeratory adorned of test board is the required configuration of torque converter oil Flow Measuring System, does not belong to Hydraulic Power Transmission System).
Because working pressure servo variable displacement motor is provided with the control oil pump group that control pressure signal is provided to oil motor in the system, can carry out continuous linear stepless variable to main motor displacement by the pressure of regulating this pump group, thereby control the motor output speed easily.
Be provided with secondary pressure operation valve group in the system, can under the condition that does not change the main pump setting, adjust the maximum working pressure (MOP) (this pressure is not more than the main pump set pressure) of main system, because this valve group is only carried out the efficiency test work that drags in the load testing at wheel box, and pre-set parameter directly influences the working pressure of main oil pump, therefore must not change the state of this valve group when other test tests.
