Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further details.
Embodiment one
As shown in Figure 1, the utility model provides a kind of damaged vehicle braking performance detector, comprise load bar 1, damping force loader 2, braking force sensor 3, be arranged on the brake pedal force sensor 6 on pedal, data collecting card 7 and computing machine 8, described load bar 1 one end is provided with the flange 4 for connecting wheel, the other end is provided with the adjustment block 5 that can adjust loading position, described damping force loader 2 is positioned at immediately below adjustment block 5, braking force sensor 3 is provided with between described damping force loader 2 and adjustment block 5, described braking force sensor 3 is connected with data collecting card 7 respectively with brake pedal force sensor 6, described data collecting card 7 is connected with computing machine 8.
Braking force sensor 3 is pancake radial force snesor, different according to the classification of detected vehicle, passenger car can adopt ZHBU-500kg type sensor, commercial car can adopt PSD-2tSJTT type sensor, and they all have good natural linear, offset load resistance is strong, precision is high, easy for installation stable.
Brake pedal force sensor 6 is pedal force snesor, can adopt the sensor of MLA-1KNA model, without the need to transforming pedal, easy for installation, slim light weight, and the measuring error that pedal position causes is little.
Damping force loader 2 is for cultrating or cylindricality jack type loader, highly lower, deadweight is comparatively light, and load-bearing capacity is large, highly versatile.
Connecting hole for the flange 4 connecting wheel is the elongated hole of circumferentially extending, is applicable to tire centerline apart from different vehicles, applied widely.
The surface that adjustment block 5 is contacting with braking force sensor 3 is provided with spherical pit, can fasten with the spherical pit of adjustment block 5 with braking force sensor upper end hemisphere jut, be connected effective, be convenient to the transmission of loading force, prevent from occurring between loader and load bar rocking, accuracy of detection is high.
Be relative removable connection between adjustment block 5 with load bar 1, rail mounted can be selected to connect or the connection of many fixed positions formula, by the adjustment position of adjustment block on load bar, realize the difference of loading force, thus realize the detection of the braking ability of different automobile types.
Embodiment two
The place different from embodiment one is, pedal arranges Self-pressurizing agri mechanism, and the mode of pedal Self-pressurizing agri has:
1, screw body regulates and arranges screw body on the surface at brake pedal force sensor, reaches different pedal brake power by regulating screw mandrel.
2, Serve Motor Control hydraulic/pneumatic cylinder regulates pedal place in car to install Serve Motor Control hydraulic/pneumatic cylinder assembly, according to the position of car seat mounting points, the height of adjustment aluminum alloy frame lower margin, position, all around, enable to be connected and fixed with Seat-fixed point.Servomotor is retracted into cylinder tail position, the front and back position of adjustment cylinder tail rotating shaft, makes loading nylon head bottom and pedal force sensor surface contact.
