Abstract
The utility model discloses a forward and reverse force measurer for the brake testing platform of a motor vehicle. The forward and reverse force measuring device is composed of a support frame, pressure sensors, contact heads, a force measuring arm, connecting bolts, locking nuts, etc., wherein, one end of the two pressure sensors is arranged on the support frame by the connecting bolts; the other end of the two pressure sensors is respectively provided with the contact heads, and is locked; one end of the force measuring arm is arranged at the middle part between the upper and the lower contact heads to be served as a fulcrum; when the other end of the force measuring arm is subjected to forward or reverse brake force, the end surface, of the other end of the force measuring arm, which contacts the contact heads pushes or depresses the contact heads, thus the upper or the lower pressure sensor is stressed, and thus the forward or the reverse brake force can be measured.
Description
The utility model belongs to delivery vehicle performance of motor vehicle detection technique field, relates to the forward and reverse device for measuring force of a kind of motor vehicle brake test bench.
At present, detect in the industry, utilize brake test bench can only detect forward damping force, detect then powerless plugging power to the detection of motor vehicle brake power at China's performance of motor vehicle.
The purpose of this utility model provides the device for measuring force of the forward and reverse damping force of a kind of motor vehicles, can carry out forward and reverse service brake power to it, and the detection of forward and reverse parking braking power is to satisfy the requirement of motor vehicle brake performance detection.
The utility model adopts following technical scheme to realize: be installed on the brake platform underframe the motor vehicle brake test bench just, reverse device for measuring force, comprise the positive pressure sensor, support, contact, the dynamometry arm, positive pressure sensor bottom is fixed on the support lower end with coupling bolt, contact is threaded with sensor top, and lock by set nut, dynamometry arm one end is positioned at above the contact, the other end is installed on the flange of drive roll reducing motor of motor vehicle brake platform, it also comprises a buffer brake sensor, its underpart is fixed on the support upper end by coupling bolt, positive pressure sensor and buffer brake sensor are positioned on the same axis, buffer brake sensor top is equipped with a contact, and contact is relative with the contact of positive pressure sensor.
The utility model is simple in structure, easy to operate, the dynamometry data are accurate, can frequently carry out forward and reverse commutation dynamometry, the forward and reverse dynamometry sensor two-way (tension and compression) that is not stressed returns the time and the drift influence of the resetting of zero, satisfied the requirement of motor vehicle brake Performance Detection, met GB11798.9-89 " brake tester of reaction roller type calibrating technical conditions ", forward and reverse test error all＜± 3%.
Below in conjunction with instantiation the utility model is further described:
Accompanying drawing 1 is the structural representation of forward and reverse device for measuring force.
As shown in the figure: device for measuring force is installed on the brake platform underframe, and pressure transducer 1 usefulness coupling bolt 8 is fixed on support 4 upper ends, and pressure transducer 3 usefulness coupling bolts 8 are fixed on support 4 lower ends, and two attachment bolts are also kept vertically on same axis; Contact 7 and pressure transducer 1 thread connection, contact 6 and pressure transducer 3 thread connection, dynamometry arm 2 one ends are the maintenance level in the middle of two contacts, adjust two contacts, the free gap that makes the dynamometry arm is 0.5-1mm, and two contacts are locked (the dynamometry arm other end is installed on the flange of motor vehicle brake platform drive roll reducing motor) with set nut 5 and pressure transducer respectively.After the wheel of tested vehicle is by the drive roll forward drive of driven by motor, when tested car brakeing, wheel applies and the opposite power of drive roll linear velocity direction, and this power is depressed contact 6 by dynamometry arm 2 one ends, make positive pressure sensor 3 stressed, promptly record forward damping force.On the contrary, the wheel of tested vehicle by the drive roll reverse drive of driven by motor after, when tested car brakeing, dynamometry arm 2 top upper contact heads 7 make buffer brake sensor 1 stressed, promptly record plugging power.
