Abstract
The utility model relates to a circulating test bench for a hand brake, which comprises a rack, a pulley, a simulation load measuring instrument, an oil cylinder, a hand brake, a coupling, a hydraulic station and a pulling force rod, wherein a displacement sensor is arranged on the oil cylinder; a force sensor is arranged on the pulling force rod; and the other end of the displacement sensor and the other end of the force sensor are connected with a microcomputer control system. With the adoption of the circulating test bench for the hand brake, the testing of braking, release and force adjustment functions and all test items of chain output force test and circulation test of the hand brake can be continuously completed, the workload is small, the testing time is short, the efficiency is high, the cost is low, and data acquired in test is precise.
Description
Technical field
The utility model relates to a kind of test unit, is specifically related to a kind of hand brake cyclic test platform.
Background technology
Alleviate reduction gear for whether the performance of checking hand brake meets design requirement, whether needs installing, in order to understand the abrasion situation of checking between each parts, just need carry out unloaded torsional moment test, brake test, alleviation test, the test of accent power, chain output tensile test and cyclic test.The testing table of existing hand brake is special testing table, whenever finishes an experiment, just hand brake need be unloaded from testing table, refills on another testing machine, carries out the next item down test.Finish all test subjects of hand brake, the time is long, and labour intensity is big, and efficient is low, expense height, test image data out of true.
Summary of the invention
The purpose of this utility model is the shortcoming that overcomes above-mentioned technology, the hand brake cyclic test platform that provide a kind of and can test continuously, workload is little, test period is short, efficient is high and expense is low.
Hand brake cyclic test platform of the present utility model comprises frame, pulley, simulation load measuring instrument, oil cylinder, hand brake, shaft coupling, Hydraulic Station and stayed mast, it is characterized in that: have additional displacement transducer on the described oil cylinder, have additional force transducer on the stayed mast, the other end of displacement transducer and force transducer is connected with Control System of Microcomputer.
Hand brake cyclic test platform of the present utility model can be finished braking, alleviation, the accent power function test of hand brake continuously, test of chain power output and cyclic test all test subjects, workload is little, test period is short, the test image data is accurate, efficient is high and expense is low.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Among the figure 1, oil cylinder, 2, hand brake, 3, shaft coupling, 4, the simulation load measuring instrument, 5, Hydraulic Station, 6, stayed mast, 7, force transducer, 8, displacement transducer, 9, frame, 10, pulley.
Embodiment
Hand brake cyclic test platform of the present utility model is made of frame 9, pulley 10, simulation load measuring instrument 4, oil cylinder 1, hand brake 2, shaft coupling 3, Hydraulic Station 5 and stayed mast 6 as shown in the figure.Have additional displacement transducer 8 on oil cylinder 1, have additional force transducer 7 on the stayed mast 6, the other end of displacement transducer 8 and force transducer 7 is connected with Control System of Microcomputer.
During test, with displacement transducer 8, after stayed mast 6 connects with system controlled by computer, select test type then, starter gear, the test image data is accurate, automatically finish braking, alleviation, the accent power function test of hand brake, test of chain power output and cyclic test project.
