Abstract
The utility model discloses a mounting structure for a force transducer of an auto chassis dynamometer, which comprises an erection support (10) and a force transducer (20) fixed on the erection support, wherein, the force transducer (20) is connected with an arm end of a torque arm (21); and the erection support (10) is mounted and fixed on a floor level of a foundation pit (30) by fasteners (11). The utility model has the beneficial effects that as the erection support is separated from a frame and is independently mounted and fixed on the floor level of the foundation pit, so that the force transducer is not susceptible to the frame vibration, and the testing accuracy of the force value can be guaranteed.
Description
Technical field
The utility model relates to road simulation dynamometer, particularly the force cell mounting structure of road simulation dynamometer.
Background technology
The technology status of automobile chassis is related to the travel control stability and the security of car load, also influences the transmission of power and the fuel consume of engine simultaneously.Road simulation dynamometer is the indoor checkout equipment that can detect, analyze and judge the parameter relevant with dynamic property, economy, maneuverability and the security of automobile.
Road simulation dynamometer mainly is made up of dynamometer machine stand and control system, and the dynamometer machine stand is arranged in the foundation ditch on the detection line.The dynamometer machine stand is made of cylinder, eddy current absorption dynamometer, device for measuring force, speed measuring device, inertia simulation device and lifting device etc., and wherein, device for measuring force mainly is made up of toggle, force cell.Toggle is installed on the stator of eddy current absorption dynamometer, and force cell is fixed on the erection support and with toggle arm end and is connected.
In the testing process, the interaction in current vortex and its magnetic field forms braking moment to rotor, and its action direction is opposite with rotor sense of rotation on being serially connected with cylinder, produces tangential force on wheel circumference.Meanwhile, stator also is subjected to an equal and opposite in direction, moment that direction is opposite, and it forces toggle to rotate, and toggle is just to installing the force cell generation pressure of location.Be subjected to the pressure of toggle when force cell after, produce strain,, can obtain certain output voltage, the signal transition of power is become electric signal,, just can obtain acting on the power value on the force cell through demarcating by strain amplifier.
In the existing road simulation dynamometer, the erection support of force cell is fixedly mounted on the frame, because testing process intermediate roll high-speed rotation can cause frame vibration, will cause measured power value to fluctuate, measuring accuracy is constituted very big influence in a big way.
The utility model content
Technical problem to be solved in the utility model provides a kind of road simulation dynamometer force cell mounting structure, and this mounting structure can be eliminated the influence of frame vibration to measuring accuracy effectively.
The technical scheme that its technical matters that solves the utility model adopts is: road simulation dynamometer force cell mounting structure of the present utility model, comprise erection support and the force cell that is fixed thereon, force cell is connected with toggle arm end, and it is characterized in that: described erection support is fixed on the terrace of foundation ditch by securing member.
The beneficial effects of the utility model are, because erection support and frame are separated, independently are fixed on the terrace of foundation ditch, make force cell not be subjected to the influence of frame vibration, can guarantee the measuring accuracy of power value.
Description of drawings
This instructions comprises following two width of cloth width of cloth accompanying drawings:
Fig. 1 is the structure and the mounting means synoptic diagram of automobile chassis measurement of power;
Fig. 2 is the synoptic diagram of the utility model road simulation dynamometer force cell mounting structure.
Parts, toponym and pairing mark among the figure: erection support 10, securing member 11, force cell 20, toggle 21, foundation ditch 30.
Embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
See figures.1.and.2, road simulation dynamometer force cell mounting structure of the present utility model, comprise erection support 10 and the force cell 20 that is fixed thereon, force cell 20 is connected with toggle 21 arm ends, and described erection support 10 is fixed on the terrace of foundation ditch 30 by securing member 11.Because erection support 10 is separated with frame, make force cell 20 not be subjected to the influence of frame vibration, can guarantee the measuring accuracy of power value.Securing member 11 adopts swell fixture, foot bolt etc.
Some principles of the above the utility model road simulation dynamometer force cell mounting structure that just explains through diagrams, be not be the utility model to be confined to shown in and in described concrete structure and the scope of application, so every the corresponding modify and equivalent that might be utilized all belongs to the claim that the utility model is applied for.
