Description
Technical field
The present invention relates to a kind of motor vehicle performance of parking brake pick-up unit, particularly the towed performance of parking brake pick-up unit of the all-hydraulic intellectuality of one.
Background technology
Performance of parking brake is the basic usability ensureing automobile safety operation, obtain expection operational effect, and performance of parking brake inspection is the important Interventions Requested of motor-vehicle inspection.According to the regulation of GB7258-2012 " motor vehicle safe and technical specification " and GB21861-2014 " Vehicle Security Interventions Requested and method " standard, performance of parking brake inspection has road to try inspection and two class methods checked by stand.Current automobile safety Performance Detection mechanism and inspect on colligated-function mechanism mainly adopt two kinds of methods to vehicle parking Performance Detection: adopt brake tester inspection for the vehicle can going up brake test bench, for going up brake test bench and to the contentious vehicle of rig test result, adopt the examination inspection of ramp road.
According to 7.10.4 regulation in GB7258-2012 " motor vehicle safety inspection technical conditions ": the ramp performance of parking brake method of inspection is: in the unloaded state, holding brake device can ensure that motor vehicle be the motor vehicle that 20%(is kerb weight less than 1.2 times to gross mass in the gradient is 15%), the attachment coefficient on tire and ground is greater than, equal the slope Dao Shangzhen of 0.7, anti-both direction keeps maintaining static, and the time should be more than or equal to 5min.Check according to ramp parking, then need special construction can provide 15% and 20% two kind of gradient the parking test ramp of overall dimensions of a car can be held, for truck combination parking ramp needed for two-way ramp length at least 40 meters, width is not less than 3.5 meters, and floor area is about 140 square metres.When building satisfactory ramp, can run into the restriction of site area, great majority do not have vacant place to build parking ramp.In addition, must set up for the inspection of long wheelbase, long vertical the phenomenon that sufficiently long transition ramp " drags the end " to prevent vehicle; Serious potential safety hazard is also there is in the process that the upper and lower ramp of oversize vehicle and parking are checked.Because this ramp utilization factor is extremely low, add the big and medium-sized cities land-use factor of an inch of land is an inch of gold, Geng Shi motor vehicle detecting mechanism is difficult to provide parking ramp.
According to the regulation of GB7258-2012 " motor vehicle safe and technical specification " and GB21861-2014 " Vehicle Security Interventions Requested and method " standard, the examination inspection of motor vehicle parking performance road adopts ramp inspection.When not possessing test ramp, can refer to relevant criterion and using the instrument test performance of parking brake conformed with the regulations.Performance of parking brake pick-up unit adopts the method for testing of tractive force, eliminate the place and expense of building test run ramp, avoid the deficiency of bench teat inspection, the examination requirements of all kinds (comprise and cannot go up brake test bench and test run ramp) motor vehicle can be met.
At present, motor vehicle detecting mechanism, because of the restriction of site area, is difficult to build parking test ramp, thus needs a kind of all-hydraulic intellectuality of exploitation towed performance of parking brake pick-up unit to replace current parking ramp.Meanwhile, the traction reinforcing method used at present has manually that (electronic) cucurbit pulls method, worm and gear machinery (electronic) adds force method and hydrostatic transmission adds force method etc., but the afterburning method poor reliability of first two, especially add force method with hydrostatic transmission the most reliable and the most stable.
Summary of the invention
The technical problem to be solved in the present invention be to provide a kind of by site area restriction, easy and simple to handle, measure accurately, use safety, low cost of manufacture, the towed performance of parking brake pick-up unit of the reliable all-hydraulic intellectuality of afterburning method taked.
For solving the problems of the technologies described above, technical scheme of the present invention is: the towed performance of parking brake pick-up unit of a kind of all-hydraulic intellectuality, and its innovative point is: comprise the display of firm banking, hydraulic haulage power generating means, hydraulic verticallifting device, force cell and intelligent data and controlled processing unit; Described firm banking comprises L-type plate and a pair reinforcement, and the axis place of the vertical direction of L-type plate is provided with a rectangular channel; Described a pair reinforcement is arranged on the two ends of the long axis direction inside L-type panel; Described tractive force generating means comprises apparatus main body, force cell and slide block, and the width of described slide block is identical with the width of rectangular on L-type plate, and is arranged in rectangular channel; The middle part of described apparatus main body is fixedly mounted on the center of slide block, and one end of apparatus main body connects force cell; Described force cell one end is connected with outside tested device, and output terminal shows with intelligent data and is connected with control module; Described hydraulic verticallifting device is arranged on the axis place of L-type plate vertical direction, and lower end is connected with the top of slide block.
Further, described intelligent data indicative control unit is by programmable controller, lcd touch Displaying Meter and can form by controlled encoder.
The invention has the advantages that:
(1) firm banking of the present invention is pure frame trigonometric expression supporting construction, and strong, safe, reliable, intensity is high;
(2) hydraulic verticallifting device and hydraulic tracting vehicle generating means provided lastingly by hydraulic power unit, the transmission of stable power;
(3) elastomer alloy material selected by force cell, and existing rigidity ensures that the consistent and deformation of deformation recovers, and has again good Corrosion Protection, simultaneously also can accurate transfer by force information and remain on identical stressed time deformation consistance and reset property completely.
(4) intelligent data indicative control unit comprises programmable controller, lcd touch Displaying Meter, can controlled encoder, not only testing result can be shown intuitively at Displaying Meter during detection, but also print detection data by data control system, and testing result can be sent to the networked devices such as online computer;
(5) this kind of proving installation be not by the restriction of the type of vehicle factors such as vehicle wheelbase length, preponderance, can cover all vehicles; Also have simultaneously easy to use, floor area is little, it is accurate to measure, easy and simple to handle, the feature such as low price, use safety.
