Embodiment
For that can further appreciate that the contents, features and effects of the utility model, the following examples are hereby given, and coordinates attached drawing Describe in detail as follows.It should be noted that the present embodiment is descriptive, it is not limited, it is impossible to thus limit this practicality New protection domain.
A kind of brake-pedal of automobile limit detection platform, including base 1, column 5, suspension gantry 3, pedal support 2 and brake Car pedal 13, wherein brake pedal are installed in pedal support, and the pedal support, suspension gantry and column are perpendicularly fixedly arranged on successively On base, pneumohydraulic pressure-cylinder 4 is installed in brake-pedal of automobile limit detection platform, is hinged with and is used at the top of the pneumohydraulic pressure-cylinder With the lifting gear of the adjustable connection of column, the lifting of pneumohydraulic pressure-cylinder middle part is adjustably hung in suspension gantry, and gas-liquid pressure-boosting Cylinder output terminal is hinged with the briquetting 12 that brake pedal is trampled for simulating.
One face compound sticking of briquetting is useful for being formed with connecting shaft with the rubber cushion of brake pedal snubber contact 17, briquetting another side 16, which extends transversely through 15 end of piston rod of pneumohydraulic pressure-cylinder, and is rotatably connected with piston rod end;At the top of briquetting with Check chain 14 for limiting the briquetting upset free degree is installed between piston rod.
Suspension is provided with hoist engine 11 on gantry, and steel wire rope 10, steel wire rope one end and gas-liquid pressure-boosting are wound with hoist engine It is fixedly connected in the middle part of cylinder.
Lifting gear includes elevator group 8, guide rail 9 and lifting slider 7, and guide rail is vertically fixedly mounted with its central post one side, Be slidably installed lifting slider on the guide rail, and be slidably installed elevator group on the another side of column, and elevator group and sliding block it Between be installed with connecting rod 6, provide power by elevator group, band movable slider and elevator group combination lifting.
Pressure sensor 18 for detecting brake pedal stress is installed on pedal support, and is stepped on for detecting brake The high-speed camera 19 of plate displacement and running orbit.
In addition pneumohydraulic pressure-cylinder practical in the utility model preferably selects German TOX.S1.50.32.6 types gas-liquid to increase Cylinder pressure.
In addition, brake pedal assembly 20 is fixedly connected by cushion block 21 with pedal support side wall, can be thick by adjusting cushion block The spacing of degree control brake pedal and pneumohydraulic pressure-cylinder output terminal.
More clearly to describe the specifically used mode of the utility model, a kind of example is provided below:
The utility model should first adjust pressurized cylinder height before practicality, and hoist engine and lifting are controlled by exterior PLC controller Unit carries out lift adjustment action, for the brake pedal of different type vehicle, can adaptably adjust pneumohydraulic pressure-cylinder entirety Height and angle of inclination, and calculate according to the air line distance of brake pedal bottom and brake pedal assembly curve rail when it is trampled Mark, and the curvilinear path is input in PLC controller, gas-liquid pressure-boosting cylinder piston rod is controlled by hoist engine and elevator group in real time During stretching, its height and angle of inclination, reach control pneumohydraulic pressure-cylinder output terminal and apply pressure along the track of trampling of brake pedal Purpose, and make the power output of gas-liquid pressure-boosting cylinder piston rod vertical with the contact surface of brake pedal all the time.
The utility model is preferable, and briquetting can be foot mould made of hard material, the connection shaft position simulation on briquetting Driver's ankle position is set, and check chain one end is fixedly connected with the piston rod of pneumohydraulic pressure-cylinder, and the other end is fixedly connected on foot On the toe of mould, so that the complete simulated automotive driver of pressure suffered by the contact surface of brake pedal tramples brake pedal Pressure (i.e. the pressure of trampling of driver's heel tramples pressure slightly larger than toe).
The pressure sensor of the utility model is fixedly mounted on the side wall of pedal support, since brake pedal is bent Shape, the salient point that it bends can be closely pressed together on pressure sensor, at this time due to gas when pedal force is displaced to extreme position The power output of liquid pressurized cylinder is certain, the detection numerical value of its pressure sensor is about that the power output of pneumohydraulic pressure-cylinder subtracts brake pedal The recuperability of assembly inner spray construction, i.e., after multiple limit test, spring structure inside brake pedal can because of fatigue and Failure, the pressure value that pressure sensor detects at this time can be substantially equal to the direct power output of gas-liquid pressure-boosting cylinder piston rod, It can determine that brake pedal assembly malfunction and failure at this time.
