Description
Technical field
The present invention relates to a kind of tyre tester, be specifically related to a kind of tyre tester of pressure stability.
Background technology
In engineering truck industry, the resistance to hysteresis loss performance of tyre tester to tire of most of producer all application specific is tested, and existing tyre tester bears comparatively stable pressure nearly all selected hydraulic loaded mode to ensure the tire moment, but there is system complex in hydraulic loaded, high in cost of production shortcoming.At present in order to change the present situation of tyre tester hydraulic loaded, having and adopting approach screw to load it, thus reducing costs and simplied system structure.But carry out in process of the test at tire, because surface of tyre can produce wearing and tearing, the diameter of tire can diminish gradually, and diameter of tyres diminish after screw rod load and will produce larger fluctuation and even load disappearance.So the problem that we will solve is, eliminates or reduce the pressure surge because diameter of tyres produces because wearing and tearing diminish.
Summary of the invention
In order to solve above-mentioned Problems existing, the invention provides a kind of tyre tester of pressure stability, the pressure surge that elimination or reduction produce because tire wear causes diameter to diminish.
Technical scheme of the present invention is: a kind of tyre tester of pressure stability, comprises base, and one end of described base is installed with bracing frame, the other end is installed with afterburning seat; Parallelly above described base be provided with two afterburning crossbeams, the two ends of two afterburning crossbeams connect into shaped as frame respectively by connecting link; One of them connecting link is connected with support frame as described above by articulated elements, and afterburning crossbeam is rotated around articulated elements; Another connecting link is connected with described afterburning seat by screw rod, and the bottom of described screw rod is threaded with afterburning seat, and the top of screw rod is provided with feeding pressure stabilizing device, and the top that described feeding pressure stabilizing device is positioned at described connecting link is afterburning to it; The middle part of two afterburning crossbeams is respectively installed with a bearing seat, is arranged between two bearing seats by installation shaft by tire; Be positioned at the cylinder base immediately below tire being fixed with and rotating for tire on the drive wheels.
Further, described cylinder is connected with motor by synchronous belt.
Further, the top of described screw rod is provided with boss, and described feeding pressure stabilizing device is between described boss and the connecting link connecting two afterburning seats.
Further, described feeding pressure stabilizing device comprises the upper orienting sleeve, spring, lower orienting sleeve and the pressure transducer that are set in successively from top to bottom below screw rod boss; Described screw rod boss is arranged with the roller packing ring for rotating.
The two ends of the afterburning crossbeam of this testing table connect in framed structure by connecting link respectively, connecting link in framework one end is connected with the bracing frame be installed on base by articulated elements, afterburning crossbeam entirety can be rotated around articulated elements, thus facilitates the installation and removal of tested tire.The other end connecting link of afterburning crossbeam is equipped with screw rod, between screw tip boss and connecting link, is provided with feeding pressure stabilizing device, be threaded connection between the bottom of screw rod and the afterburning seat being installed on base.The distance between feeding pressure stabilizing device and afterburning seat will be changed by rotary screw, thus reach the object applying normal pressure to tested tire.Tested tire is arranged between diaxon bearing by installation shaft; By executing downward pressure to afterburning crossbeam, making tire bottom and cylinder close contact, when machine operation, driving cylinder to rotate by synchronous belt, namely driving tire to rotate together, and then the true applying working condition of simulation tire.
Screw rod runs through the connecting link having roller packing ring, upper orienting sleeve, spring, lower orienting sleeve, pressure transducer and the afterburning crossbeam of connection two from top to bottom respectively.Wherein roller packing ring is to make screw rod can easily rotate under Afterburning condition; Upper orienting sleeve and lower orienting sleeve are that spring steadily and not produces rocks in order to make spring stress remain in compression process; Pressure transducer can show whole device in real time to produce great pressure to tire, is convenient to applying and the control of pressure; Afterburning horizontal beam action is balancedly delivered on tested tire by bearing seat by the pressure that augmentor produces.
During the work of this testing table, be regulate distance between afterburning crossbeam right-hand member and afterburning seat by rotary screw, thus change the size being applied to normal pressure on tire.When being tested tire increase pressure, rotary screw, screw rod enters the depth down of afterburning seat inside, distance between screw rod upper end and afterburning seat is diminished gradually, thus force spring-compressed, the spring now compressed can store certain elastic potential energy and act on afterburning crossbeam always, and simultaneously pressure transducer can show the size of pressure, and this potential energy is comparatively stabilising force.If diameter diminishes and makes the distance between afterburning crossbeam and afterburning seat diminish after tire wear, rotary screw makes spring elongates supplement the distance of change, thus reaches the effect reducing the fluctuation of tire pressure.
So testing table of the present invention by screw compression spring when loading, makes spring store certain elastic potential energy in the process of compression, thus reduces the fluctuation of tire on-load pressure greatly.
