Description

A kind of pedal force stroke test instrument
Technical field
The utility model relates to the technical fields of Automobile Design and manufacture, and more specifically, the utility model relates to one kind Pedal force stroke test instrument.
Background technique
With the development of Domestic Automotive Industry, people are also more next to the maneuverability of automobile, comfort and the requirement of safety It is higher, during Automobile Design, in order to realize design verification, to mark analyze and factory before safety test, need to measure from It closes, braking, accelerator pedal power and stroke, and it is simple, at low cost, easy to operate and can be accurate to have no structure currently on the market The equipment for measuring pedal force and stroke.
Utility model content
In order to solve above-mentioned technical problem in the prior art, the purpose of this utility model is to provide a kind of pedal Lixings Journey tester.
A kind of pedal force stroke test instrument, characterized by comprising: pedestal, bracket, pressure sensor, linear transducer, Angular transducer and calculating display device;The pressure sensor is arranged on pedal;The bracket is fixed on the base, One end of the linear transducer is connect with the pedal, and the other end of the linear transducer is connected by shaft and the bracket It connects, the angular transducer is arranged in the shaft;The pressure sensor, linear transducer and angular transducer are connected to The calculating display device.
Wherein, the calculating display device is computer.
Compared with prior art, the pedal force stroke test instrument of the utility model has the advantages that
The pedal force stroke test instrument of the utility model can be used in static and dynamic real steering vectors, and measurement pedal force is simultaneously Calculate pedal travel, and the feature simple, at low cost, easy to operate with structure.
Detailed description of the invention
Fig. 1 is the schematic diagram (initial position) of the pedal force stroke test instrument of embodiment 1.
Fig. 2 is the schematic diagram (mechanical dead-centre position) of the pedal force stroke test instrument of embodiment 1.
Fig. 3 is the pedal travel schematic diagram calculation in embodiment 1.
Specific embodiment
Pedal force stroke test instrument described in the utility model is further elaborated below with reference to specific embodiment, To help those skilled in the art to have more complete, accurate to the utility model design of the utility model, technical solution and go deep into Understanding.
Embodiment 1
As shown in Figs. 1-2, the pedal force stroke test instrument of the present embodiment include pedestal 40, bracket 30, pressure sensor 10, Linear transducer 20, angular transducer 50 and computer 60.Wherein, pressure sensor 10 is arranged on pedal;Bracket 30 is fixed On the pedestal 40, one end of the linear transducer 20 is connect with the pedal, the other end of the linear transducer 20 It is connect by shaft (not shown) with the bracket 30, the angular transducer 50 is arranged in the shaft;The pressure Force snesor 10, linear transducer 20 and angular transducer 50 are connected to the computer 60.
The application method of the tester of the present embodiment is as follows:
1. regulating the position of pressure sensor, it is bonded it with pedal;
2. pressure sensor, linear transducer and angular transducer are connect with computer;
3. pedal, so that linear transducer also synchro-draw, angular transducer is started to work, computer real-time acquisition pressure The pressure data (corresponding to pedal force) of force snesor transmission, the length data of linear transducer transmission and angular transducer pass Defeated angle-data, and pedal travel is calculated according to above-mentioned data, and draw the relation curve of pedal force and pedal travel.Pedal For the Computing Principle of stroke as shown in figure 3, it is α that angular transducer, which measures the angle that linear transducer turns over, linear transducer is initial Length is L1, and the length M of its variation is measured by linear transducer, then the length of linear transducer is L2=L1+ after pedal travel M, according to the cosine law: pedal travel L3=(L1 2+L2 2-2 L1 L2cosα)0.5
The tester of the present embodiment can accurately measure braking, accelerator pedal power and corresponding formation, and pass through meter The reading and calculating of calculation machine can the current pedal force of real-time display and pedal travel, and can show that pedal force takes with what pedal was formed Line relational graph.
For the ordinary skill in the art, specific embodiment has only carried out exemplary retouch to the utility model It states, it is clear that the utility model specific implementation is not subject to the restrictions described above, as long as using the method concept of the utility model The improvement of the various unsubstantialities carried out with technical solution, or the not improved conception and technical scheme by the utility model are direct Applied to other occasions, it both is within the protection scope of the present invention.
