Description of drawings
Fig. 1 is the structural representation of building block of the present utility model.
Embodiment
The utility model is a kind of rotary drum brake tester dynamic torque measurement mechanism that is used for.It comprises: four pairs of rotary drums, and every pair of rotary drum is respectively applied for and supports a wheel; Four variable-frequency motors, every motor is connected with described a pair of rotary drum with a driving belt respectively; Four bases are used to install described four motors, and an end of each base is the other end pull pressure sensor that the size and Orientation be used to measure Motor torque is installed fixedly; The quadruplet lockset is separately fixed at and is used to pin belt restriction rotary drum on described four driving belts and rotates; One cover calibration system, this calibration system has one to demarcate arm, and an end of this demarcation arm is connected the end of rotary drum, and the other end has one to be used to hang the counterweight suspension hook.
Be described further below in conjunction with accompanying drawing.
As shown in Figure 1, it comprises:
Four pairs of totally 8 rotary drums 4, every pair of two rotary drums support a wheel 3 respectively, have a flute profile belt pulley that is contained on the rotary drum central shaft to be rigidly connected by central shaft and rotary drum on the rotary drum 4;
Four variable-frequency motors 7, every motor is connected with a pair of rotary drum 4 with a driving belt 5 respectively;
Four bases 8 are used to install four motors 7, and an end of each base and ground are fixed and the other end is installed the pull pressure sensor 9 of the size and Orientation be used to measure Motor torque;
One cover calibration system, this calibration system has one to demarcate arm 2, and an end of this demarcation arm is provided with the dowel hole other end has one to be used to hang counterweight suspension hook 1.
Wherein: driving belt 5 adopts the flute profile belts, and lockset has the tooth that the tooth with the flute profile belt matches, and this lockset is used for calibration process.
Its principle of work is:
Timing signal, at first lockset 6 is fixed on the driving belt 5, rotates, again arm 2 one ends are demarcated in the central shaft insertion that has keyway of rotary drum 4 and had in the hole of keyway to pin belt restriction rotary drum, to demarcate arm 2 with key and be connected, and realize demarcating by plus-minus counterweight on suspension hook 1 at last with rotary drum 4.Respectively each wheel is demarcated by above step.Can determine the size of wheel dynamic system power or driving force by calibration process.
During measurement, wheel of the bus closely contacts with drum surface, and frictionally relatively rotates, when wheel 3 produces damping force or driving force, wheel 3 by and the drum face between friction force pass to rotary drum 4.The moment of torsion that passes over from rotary drum 4 is delivered to the flute profile belt pulley that is installed on the motor shaft by flute profile belt pulley, flute profile driving belt 5 and directly affacts on the motor 7.Power that motor produced and direction are controlled, and motor is not only can work as power but also can be used as load for the effect of rotary drum.So in actual measurement, just realized driving or loading by motor.Motor 7 is installed in can be on the base 8 that an end rotates, and the other end of base is equipped with the pull pressure sensor 9 that can measure along the base rotation direction, and the rotating shaft of base from the sensor to the base just constituted the version that can measure moment like this.Therefore, the moment that wheel produced (forward or backwards) finally acts on the pull pressure sensor by rotary drum, motor, base, power on the sensor becomes electric signal and is sent to computing machine, computing machine is record at any time, and transient behavior damping force that wheel produced or driving force will in time be measured by system and note down.The size of the electric signal of sensor has reflected that this electric signal is handled by computing machine and is reduced into torque value from the next moment of torsion of rotary drum feedback.
