Description
Technical field
The utility model relates to the proving installation on a kind of Vehicular shift gear change hand lever, the proving installation of steering force on particularly a kind of Vehicular shift gear change hand lever belongs to vehicle detection field in the mechanical engineering.
Background technology
The vehicle hand shifting transmission system comprises shifted control crank, also claim operating rod, wheel box, linkage assembly between control crank and the wheel box, detecting stiff end is the Vehicular shift gear change hand lever steering force of ball pivot, it is check vehicle hand shift, the speed change system gear shift, the requirement of speed change maneuvering performance, in the synchronously continuous shifted process of detection of dynamic driver under vehicle running state, before and after the shifted handle, about the push-and-pull steering force of two orthogonal directions, pass judgment on the design correctness of hand shifting transmission system, assembly quality, situations such as system wear fault.Be to adopt a S shape resistance-strain pull pressure sensor or adopt the beam type resistance-strain to pull force transducer and corresponding installing mechanism at present, detect the steering force of shifted handle.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, and longitudinal size is little, can get rid of the influence of angular force and moment of torsion, and the energy clamping is 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, a but direction before and after just, can not test the steering force of space left and right directions on the operating rod, therefore can not satisfy the detection requirement of vehicle hand shift, speed change system gear shift, speed change maneuvering performance; And its handle shape is different with the handle of actual vehicle operating rod, and the driver holds appearance and do 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; 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, the proving installation of steering force on a kind of Vehicular shift gear change hand lever is provided, steering force test event with a direction of horizontal handle of the level of available technology adopting and front and back, be designed to hold the posture control crank, and before and after being increased to and about the Vehicular shift gear change hand lever steering force proving installation of two directions, changing tester constitutes and structure, it has been overcome can only the unidirectional steering force of the test space, the technical limitation that the manipulation situation of tester and actual vehicle control crank departs from, satisfied the test request of fore-and-aft direction and left and right directions steering force, the actuated situation of the people of test condition and the more realistic vehicle of operating mode, and easy accessibility is fixed.The utility model is achieved through the following technical solutions, the utility model mainly comprises: operating rod bearing, control crank head, steering force sensor, its connected mode is: the steering force sensor by screw retention on operating rod bearing, the control crank head directly is screwed with the sensitive part of steering force sensor and is connected, during test, screw off the control crank head on the tested operating rod of vehicle, with operating rod bearing together with steering force sensor fixing on it and control crank headgear on tested operating rod, and fastening fast with screw.
Steering force sensor of the present utility model adopts elongated cylindrical beam type resistance-strain load sensor, the mode of connection of two of positioned opposite groups of resistance strain gages constitutes two independently bridge diagrams on its elastic deformation component, therefore two groups of signal outputs are arranged, before and after the respectively corresponding steering force sensor and about the strain value of two orthogonal directions, that is test the push-and-pull steering force of two directions in all around on the shifted operating rod, this kind steering force sensor has the little characteristic of high test precision of volume; The steering force sensor is fixed on nut on the external thread of operating rod bearing by self inner hole thread, on the operating rod bearing axis of hard-wired steering force sensor and control crank head all with the axis coaxle of operating rod.The test signal of two directional control power on the Vehicular shift shift, be connected in the portable signal conditioning module by the cable on the proving installation, directly import portable computer then, real-time with the vehicle dynamic in travelling, test the push-pull effort of the shifted manipulation of each instantaneous driver, and can do displayed record and analysis.Technology of the present utility model be applicable to before and after all kinds hand shifting transmission system and about the synchronous dynamic test of two directional control power.
The utility model adopts the elongated cylindrical beam type resistance-strain load sensor of two direction strain outputs, has increased test event, thereby has satisfied the corresponding requirement of vehicle handling quality test; Control crank head in the utility model and operating rod coaxial cable, the control crank head of tested operating rod, can change the outfit is same control crank head, therefore more meets ergonomics, and do not change the manipulation of physical situation, the data of surveying just can not depart from actual value yet; Operating rod bearing is the sleeve shaped structure, be provided with in it and the hole of the shifted operating rod of tested vehicle with diameter, step is arranged at the top in hole, and the quick location of short transverse when being used to install the utlity model has simple in structure, reliable operation, characteristics easy to adjust are installed in use.
