Description
Technical field
The utility model relates to car brakeing and detects field of mechanical technique, more specifically says a kind of improved dull and stereotyped brake test bench.
Background technology
Dull and stereotyped brake test bench, as patent 201120280044.6 is recorded, it is collection braking, wheel load, suspension inspection, multiduty a kind of Novel test platform, has the features such as multi-functional, test rate is high, compact conformation, floor area are little.
In " 9.3.4 checks with dull and stereotyped brake test bench ", the dull and stereotyped brake test bench method of inspection and process are set forth.In the time that vehicle is braked on keep plate, vehicle inertia drives platen to move forward (only making minute movement because being obstructed), and dynamometry screw makes the distortion of damping force sensor, and the damping force size that at this moment acts on tire equals to be applied to the power on sensor.Therefore the power, recording on sensor be the damping force of wheel.
The testing process of motor vehicle on dull and stereotyped brake test bench completes at the volley, completely simulated roadway test, and the force-bearing situation of vehicle is in full accord when travelling on road.Therefore its testing result more can correctly reflect real conditions when vehicle travels on road.
Detect in application in reality, there is the defect that test accuracy and precision are not high while reflecting with dull and stereotyped brake test bench inspection braking ability in a lot of users, can cause repeatedly the problems such as measurement result comparison repeatability is good not.Find through actual testing research, the reason that causes these problems to produce is to brake the gap existing between dynamometry screw and damping force sensor on platen and occurs, when vehicle brake, braking platen often will overcome this intersegmental gap to a bit of distance of reach, can make again dynamometry screw arrive on damping force sensor, damping force could be reflected, and the existence in this gap is thus only and has directly caused measuring the inaccurate root place of structure.
Utility model content
The purpose of this utility model is to overcome the dull and stereotyped brake test bench inspection of prior art braking ability and has the defect that test accuracy and precision are not high, provide a kind of simple in structure, transformation is convenient, inspection braking ability accuracy and the high dull and stereotyped brake test bench of precision.
In order to reach above object, the utility model is achieved through the following technical solutions: a kind of improved dull and stereotyped brake test bench, comprise ground, subsider and braking platen, between described braking platen and ground, be provided with damping force sensor and dynamometry screw, it is characterized in that, in described subsider, be provided with a pre-thrust device in order to regulating brake force sensor and dynamometry screw gap leaning between ground and braking platen, described pre-thrust device comprises a jacking block, the front end of described jacking block is provided with a containing cavities, in described containing cavities, be provided with the push rod that a tail end inserts into the inner, between described push rod tail end and containing cavities bottom, be provided with a pressure spring, described push rod stretches out on the free end end face of containing cavities and is provided with a rim of a bowl, on described the rim of a bowl, be provided with a spin that is free state.
The utility model adds pre-thrust device on braking platen, make to brake dynamometry screw and damping force sensor close contact on platen, eliminate the gap existing between the dynamometry screw of braking on platen and damping force sensor, prevent from measuring the impact on measurement result of minute movement that the incipient stage brakes platen, avoid the rapid high-frequency percussion to damping force sensor simultaneously and damage the risk of sensor, in addition, although pre-thrust device exists a restraint to damping force sensor, but people in industry knows that what measure damping force sampling is between one section of linear zone, between two sections of inelastic regions that in the past comprised Near The Critical Point between the linear zone of sampling, it can affect measurement accuracy and measuring accuracy, the benchmark null value of the thrust that therefore we produce by the pre-thrust device of adjusting and adaptive raising damping force sensor, whole measuring process is avoided between the initial inelastic region of power sensor, use the good centre portion of linear sensor, so can improve well measurement accuracy and measuring accuracy.Moreover the spin leaning in front end the rim of a bowl is free state, small for other function effect such as check weighing of braking platen, even do not have.
As preferably, the tail end of described jacking block is provided with a horizontal screw, is provided with a lateral adjustments screw rod in described horizontal screw.
Different from the width in subsider gap in ground according to different braking platens, can be by the whole length of the adjusting jacking block of adjusting screw(rod), also can carry out according to the elastic force of different pressures spring the size adjustment of prefabricated power, finally reach best pre-thrust rating, thereby expand the scope of application of the present utility model.
As preferably, the downside of described jacking block is provided with a longitudinal screw, is provided with a longitudinal adjusting screw(rod) in described longitudinal screw.
According to the different factors of different brake platform pallet plate thickness and braking platen and the subsider degree of depth in ground, can be by the height of the adjusting jacking block of adjusting screw(rod), reach best thrust rating in advance, thereby expand the scope of application of the present utility model.
As preferably, described jacking block is placed on the loading plate at the bottom of described subsider, is provided with the clamping plate of the described jacking block in a pair of location on described loading plate.
A pair of clamping plate are L-shaped, design in back-to-back face-off mode, be mainly used in locating jacking block, every clamping plate can regulate with respect to loading plate again on the other hand, regulate by the chute on clamping plate and dog screw, finally make jacking block whole transverse axis center and dynamometry screw in a straight line, select this optimum position.
Beneficial effect: (1) eliminates the gap existing between the dynamometry screw of braking on platen and damping force sensor, prevents from measuring the impact on measurement result of minute movement that the incipient stage brakes platen.
(2) eliminate the gap existing between the dynamometry screw of braking on platen and damping force sensor, avoid the rapid high-frequency percussion to damping force sensor and damage the risk of sensor.
(3) thrust that adjustable pre-thrust device produces, the benchmark null value of adaptive raising damping force sensor, whole measuring process is avoided between the initial inelastic region of power sensor, used the good centre portion of linear sensor, improve measurement accuracy and measuring accuracy.
