The utility model mainly comprises an operating lever seat, an operating force sensor, an operating handle head and a handle connecting rod. The utility model has the connecting mode that the operating force sensor is fixed at the side face of the operating lever seat via screws; the operating handle head is directly and fixedly connected with the sensitive position of the operating force sensor via the handle connecting rod by the screws. The utility model has the advantages that the utility model has simple structure, low cost, reliable work, convenient installation and adjustment; the utility model is in accordance with the actual operating conditions of vehicles. The utility model is suitable for the tests of the push-and-pull force and the operating force of the parking braking levers of the vehicles and engineering machines, and other operating levers.
Description
Technical field
The utility model relates to the proving installation of a kind of proving installation of operation force on operation rod, particularly a kind of operation force on operation rod, belong to vehicle detection field in the mechanical engineering.
Background technology
The push-and-pull steering force of vehicle or some engineering machinery operating rod is the major parameter of catanator maneuvering performance, passes judgment on the situation such as design correctness, assembly quality, system wear fault of catanator by continuous detection of dynamic driver push-and-pull steering force of operating rod in the vehicle ' process.Present technology is to adopt a S shape resistance-strain pull pressure sensor or adopt the beam type resistance-strain to pull the steering force that force transducer and corresponding installing mechanism detect operating rod, find by literature search, China Patent No. is: 90221808, name is called: pull force tester, this patent has been introduced a kind of by pulling the force tester that pulls that force transducer and digital displaying meter form, the power that pulls that is applicable to automobile parking braking control and other operating rod is measured, its sensor design compactness, longitudinal size is little, can get rid of angular force and moment of torsion influence and can clamping on the tested pull bar of various forms and size; Design has sampling in its digital displaying meter, holding circuit and digital latch circuit, decapacitation shows outside each instantaneous hand value of thrust, can also automatically catch and show maximum hand value of thrust, and it is for good and all remained on the display board, a complete set of instrument reflection is sensitive, easy to use, be easy to make, every precision and index all can satisfy test request.Though this utility model can testing vehicle parking braking control and the power that pulls of other operating rod, but handle shape is different with the handle of actual vehicle operating rod, the driver holds appearance and does not meet human body manipulation of physical situation, and the control steering force of the value that records like this when not having the installation testing instrument is different; And the mode that this utility model adopts fixture block to clamp the tested vehicle operating rod installs and fixes, and the adjustment location of its short transverse is convenient inadequately, so this The Application of Technology scope is very limited.
Summary of the invention
The utility model is at the deficiencies in the prior art and defective, a kind of proving installation of operation force on operation rod is provided, with the horizontal handle of the level of available technology adopting, be designed to hold the joystick manipulation force test device of posture handle, changing tester constitutes and structure, make the adjustment location of the departing from of its manipulation situation that has overcome tester and actual vehicle control crank, short transverse and the technical limitation of inconvenience is installed, the actuated situation of the people of test condition and the more realistic vehicle of operating mode, and the adjustment location of short transverse is convenient when installing.The utility model is achieved through the following technical solutions, the utility model mainly comprises: operating rod bearing, steering force sensor, control crank head and handle connecting link, its connected mode is: the steering force sensor is by the side of screw retention at operating rod bearing, the control crank head is directly fixedlyed connected with the sensitive part of steering force sensor with screw by the handle connecting link, during test, screw off the control crank head on the tested operating rod of vehicle, operating rod bearing is enclosed within on the tested operating rod, and fastening fast with screw.
Steering force sensor of the present utility model adopts rectangle or elongated cylindrical beam type resistance-strain load sensor, be used to test the strain value of fore-and-aft direction on the operating rod, that is the human body push-and-pull steering force of fore-and-aft direction on the test operating rod, this kind steering force sensor has measuring accuracy and high reliability features; The endoporus parallel axes of the mounting plane of steering force sensor and operating rod bearing, the endoporus axis coaxle of the axis of control crank head and operating rod bearing or parallel.Operating rod bearing is the sleeve shaped structure, is provided with in the operating rod bearing and the hole of tested operating rod with diameter, and step is arranged at the top in hole, the quick location of short transverse when being used for the proving installation installation.The test signal of operation force on operation rod, be connected in the portable signal conditioning module by the cable on the proving installation, directly import portable computer then,, and can do displayed record and analysis with each instantaneous driver-operated push-pull effort of the vehicle dynamic real-time testing in travelling.Technology of the present utility model is applicable to the push-and-pull steering force test of vehicle, engineering machinery parking braking and other operating rod.
The utility model control crank head and operating rod coaxial cable, the control crank head of tested operating rod, can change the outfit is same control crank head, so more meet ergonomics, and does not change the manipulation of physical situation, the data of surveying just can not depart from actual value yet; Operating rod bearing in the utility model is the sleeve shaped structure, be provided with in it and the hole of tested operating rod with diameter, step is arranged at the top in hole, the quick location of short transverse when being used for the proving installation installation, the utlity model has simple in structure, cost is low, measuring accuracy is high, reliable operation, and characteristics easy to adjust are installed.
