Preferably, described flywheel is multiple.
Preferably, the above-mentioned Comprehensive Testing Facility for detecting parking performance also comprises fixing back up pad.
A kind of system for detecting parking performance comprises: as above for detecting the Comprehensive Testing Facility of parking performance; Rotating speed, torque sensor; Differential mechanism; Wheel box; Halting mechanism; Described 3rd belt wheel is connected with a semiaxis output terminal of described differential mechanism, described 4th belt wheel is connected with another semiaxis output terminal of described differential mechanism by described rotating speed, torque sensor, the input end of described differential mechanism is connected with the output shaft of described wheel box, and described halting mechanism is arranged on described transmission internal.
The utility model utilizes Hydraulic Station first to drive the first belt wheel and by belt drive the 3rd belt wheel, then the first band wheel drive flywheel simulation car load moment of inertia, then flywheel drives the second belt wheel and by belt drive the 4th belt wheel, for two semiaxis output terminals of differential mechanism provide power to realize, wheel box is counter drags again for 3rd belt wheel and the 4th belt wheel, when the independent output torque of needs, Hydraulic Station not flywheel driven rotates, when needs simulation moment of inertia, Hydraulic Station is rotated by the first band wheel drive flywheel, at process of the test medium speed, torque sensor detects moment of torsion and rotating speed, therefore the simulation of moment of torsion output and moment of inertia just can be realized using a Hydraulic Station as power source, sense cycle and cost all reduce.
Further, multiple flywheel is adopted can to make the simulation of moment of inertia more close to actual.
Further, fixed support plate in advance, is then arranged on fixed head by wheel box etc., relies on fixed head can ensure the installation accuracy of wheel box, differential mechanism, ensures accuracy of detection further.

Embodiment
With reference to figure 1, at the present embodiment for detecting in the Comprehensive Testing Facility of parking performance, on the direction coaxial with the output shaft of Hydraulic Station 1, first first belt wheel 2 is connected with Hydraulic Station 1 thus is subject to the driving of Hydraulic Station 1, then the first flywheel 3 is coaxially connected with the first belt wheel 2, second flywheel 4 is coaxially connected with the first flywheel 3 again, and the second belt wheel 5 is coaxially connected with the second flywheel 4 again.First flywheel 3 and the second flywheel 4 are for simulating car load moment of inertia, certainly, those skilled in the art also only can adopt a flywheel or adopt the flywheel more than two, and the flywheel quantity adopted is more many more can accurately simulate car load moment of inertia, but general two is enough substantially.Below above-mentioned each parts, there is the 3rd belt wheel 10 and the 4th belt wheel 7, wherein the first belt wheel 2 is by the first belt 11 to the 3rd belt wheel 10 transmission, and the second belt wheel 5 passes through the second belt 6 to the 4th belt wheel 7 transmission.Space between 3rd belt wheel 10 and the 4th belt wheel 7 is for installing UUT.Back up pad 12 is fixed on the pedestal of ground or whole stand in advance, and namely back up pad 12 does not do translation or rotation.
The whole system architecture for detecting parking performance is as follows:
In order to clear, in FIG differential mechanism and wheel box two parts be reduced to parts 9 and represent, be referred to as differential mechanism and wheel box 9.In fact, in normal operating conditions, there are an input end and two output terminals in differential mechanism, wherein input end is used for being connected with the output shaft of wheel box thus will coming from the power transmission of engine to differential mechanism, and two output terminals are connected with the semiaxis of two driving wheels for power transmission is realized the speed discrepancy of two driving wheels to driving wheel in turning process.Differential mechanism and wheel box 9 are fixed in back up pad 12, rely on fixed head can ensure the installation accuracy of wheel box, differential mechanism, ensure accuracy of detection further.Then rotating speed, torque sensor 8 one end are coaxially connected with the 4th belt wheel 7, the other end is connected with a semiaxis output terminal of differential mechanism 9, and the 3rd belt wheel is directly connected with another semiaxis output terminal of differential mechanism 9, still keep the input end of differential mechanism to be connected with the output shaft of wheel box, halting mechanism 13 is arranged on the inside of the wheel box in differential mechanism and wheel box 9 simultaneously.Like this, operationally, when only needing output torque, Hydraulic Station 1 does not drive the first flywheel 3 and the second flywheel 4 to rotate, moment of torsion is passed to two output terminals of differential mechanism by the first belt wheel 2 and the 3rd belt wheel 10, second belt wheel 5 and the 4th belt wheel 7, apply moment of torsion to wheel box, rotating speed, torque sensor 8 detect the torque value applied, thus inspection halting mechanism 13 braking effect in the quiescent state; When needing the moment of inertia of simulating car load, hydraulic workstation 1 drives the first flywheel 3 and the second flywheel 4 to rotate, and rotating speed, torque sensor 8 detect rotating speed and the moment of torsion of actual applying, thus inspection halting mechanism 13 braking effect in a dynamic state.Certainly, Hydraulic Station 1 itself also can have the device of display translation moment of torsion, rotating speed, but the setting position of rotating speed in the present embodiment, torque sensor 8 obviously more accurately can indicate the actual input value of differential mechanism.As seen from the above description, in the present embodiment, just can realize the simulation of moment of torsion output and moment of inertia using a Hydraulic Station 1 as power source, no longer need two stands, sense cycle and cost all reduce.
In process of the test, also can cut off the power source of Hydraulic Station 1 as required at any time.
Although the utility model is described in conjunction with above embodiment, but the utility model is not limited to above-described embodiment, and only by the restriction of claim, those of ordinary skill in the art can easily modify to above embodiment and change, but do not leave essential idea of the present utility model and scope.
