Description
Technical field
The utility model relates to motor vehicle detecting equipment, particularly a kind ofly is used to detect heavy vehicle independent suspension frame unit performance detection platform.
Background technology
Automotive suspension device monitor station is used under the situation that the automotive suspension vibroshock does not disintegrate, and the quality and the performance of automotive suspension device are carried out fast detecting.Existing automotive suspension device monitor station can only detect light-duty rigid axle suspension vehicle; The heavy vehicle independent suspension frame unit still rests on by rule of thumb and the visual detection stage; Residing situation in the time of can not accurately confirming independent suspension frame unit performance, quality and detection; Blindly maintenance is perhaps changed parts, causes the heavy vehicle roadworthiness to can not get guaranteeing, perhaps increases maintenance cost.Therefore, press for a kind of heavy vehicle independent suspension frame unit monitor station.
The utility model content
The utility model technical matters to be solved provides a kind of heavy vehicle independent suspension frame unit monitor station, can conveniently and detect heavy independent suspension for vehicle device performance effectively.
It is following that the utility model solves the technical scheme that its technical matters adopted:
The heavy vehicle independent suspension frame unit monitor station of the utility model is characterized in that it comprises: a pair of load-bearing platen is arranged on the rack table; Crossbeam and sensor, crossbeam are positioned at load-bearing platen below and are installed on the frame through the longitudinally guiding assembly, and sensor is installed between load-bearing platen and the crossbeam; Vibrator is installed on the frame and acts on crossbeam.
The beneficial effect of the utility model is conveniently and to detect heavy independent suspension for vehicle device performance effectively; Simple and compact for structure, and be easy to maintenance, maintenance.
Description of drawings
This instructions comprises following two width of cloth accompanying drawings:
Fig. 1 is the structural representation of the utility model heavy vehicle independent suspension frame unit monitor station;
Fig. 2 is the cut-open view along A-A line among Fig. 1.
Parts shown in the figure, position and pairing mark: frame 10, load-bearing platen 11, crossbeam 12, sensor 13, motor 20, energy-storing flywheel 21, eccentric wheel 22, spring 23, transmission shaft 24, guiding short rod 31, straight line sleeve 32, linear motion bearing 33.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
See figures.1.and.2, the heavy vehicle independent suspension frame unit monitor station of the utility model comprises: a pair of load-bearing platen 11 is arranged on frame 10 table tops; Crossbeam 12 and sensor 13, crossbeam 12 is positioned at load-bearing platen 11 belows and is installed on the frame 10 through the longitudinally guiding assembly, and sensor 13 is installed between load-bearing platen 11 and the crossbeam 12; Vibrator is installed on the frame 10 and acts on crossbeam 12.
See figures.1.and.2; Said vibrator comprises motor 20, energy-storing flywheel 21, eccentric wheel 22 and spring 23; Energy-storing flywheel 21 and transmission shaft 24 are installed on the output shaft of motor 20; The eccentric wheel 22 that is installed on the transmission shaft 24 acts on crossbeam 12, spring 23 longitudinal extensions, and its two ends act on crossbeam 12 and frame 10 respectively.With reference to Fig. 2, said longitudinally guiding assembly comprise stationary installation the guiding short rod on the frame 10 31 be fixedly mounted on the straight line sleeve 32 on the crossbeam 12, between guiding short rod 31 and the straight line sleeve 32 linear motion bearing 33 is set.
During detection; Vibrator forces load-bearing platen 11 and goes up seized heavy vehicle independent suspension frame unit and produces vibration; Produce one down by the effect of energy-storing flywheel 21 and (be generally 23～0Hz) to the frequency attenuation process of low frequency by high frequency; (therefore 10～15Hz) height decay to natural frequency with the heavy vehicle independent suspension frame unit when identical when the vibration frequency of load-bearing platen 11, and load-bearing platen 11 produces with the heavy vehicle independent suspension frame unit and resonates because the gyro frequency of motor 20 is than the natural frequency of wheel; Measure this resonant frequency or amplitude by sensor 13, output vibrational waveform curve.
In exciting after vibration attenuation process, load-bearing platen 11 is done vertical vibration together with the seized heavy vehicle independent suspension frame unit on it by sinusoidal rule, exciting fixed amplitude and change of frequency.Sensor 13 real-time (its data acquiring frequency should reach 500HZ at least) measures wheel and affacts the vertical on the load-bearing platen 11, and deposits force signal in storer.When seized heavy vehicle independent suspension frame unit resonates, minimum value will appear in its dynamic wheel vertical load, and the percent value of its value and static wheel vertical load is absorptivity, claim wheel ground connection sex index again, and its normative reference is as shown in table 1.
Table 1 wheel ground connection sex index normative reference
It is pointed out that some principles of top said the utility model heavy vehicle independent suspension frame unit monitor station that just explains through diagrams, because the those of ordinary skill in constructed field is easy to carry out on this basis some modifications and change.Therefore, this instructions be not be to the utility model be confined to shown in described concrete structure and the scope of application in, so every the modify and equivalent that might be utilized all belongs to the claim that the utility model is applied for.
