Abstract
The utility model relates to an automobile air suspension system test bed clamping mechanism. The clamping mechanism comprises a gantry frame, a locating and guiding mechanism, a crossbeam and a connection tray. The clamping mechanism is characterized in that, the locating and guiding mechanism and the crossbeam are connected together; the connection tray is connected with the crossbeam through the locating and guiding mechanism; the crossbeam and the gantry frame are connected together. A design technology about a clamp is applied to an automobile air suspension system test bed. Clamping of an air spring, an absorber and the like can be achieved, and therefore the purpose of convenient installation and dismounting is achieved. The clamping mechanism not only can carry out a single test of an air spring or an absorber, but also can achieve a test of a whole air suspension system. Because a special clamping mechanism is employed, the test precision is ensured and the whole test process is timesaving and convenient.
Description
Technical field
The utility model belongs to exploitation experimental facilities field, relates to a kind of vehicle air suspension system testing table clamping mechanism, and relevant jig Design technology is applied on vehicle air suspension system testing table.Can complete the clamping of air spring, vibroshock etc., thereby reaching convenient installs, the object of dismounting.
Background technology
Due to the nonlinear stiffness characteristics that air suspension self has, make its application more and more extensive.The domestic industrialization that does not also have systematic theory to support air suspension at present, automobile required air suspension product is mostly from external import.Therefore the matching technique of air suspension just becomes one of gordian technique of improving vehicle suspension system performance.Obtain the optimum matching scheme of automobile airsuspension system rigidity and damping under different working conditions, at its initial stage, to test for target vehicle, analyze, obtain the variation range of air suspension rigidity and vibroshock damping, for follow-up development lays the foundation; After theoretical evaluation work finishes, need again obtained result to verify, analyze, revise equally, for road trial work is afterwards given security.Therefore, air suspension testing table through the work of air suspension coupling all the time.
At present, vehicle air suspension system testing table does not also have the specialized apparatus of moulding.Be mostly some universities, research institute according to some existing experiment condition, add some simple pneumatic elements and test macro and complete corresponding test job.Therefore, these testing tables can only carry out the test of single air spring or vibroshock mostly.Because these testing tables are for build temporarily, air spring and vibroshock do not have special clamping tool simultaneously, and therefore whole test process is wasted time and energy, and the precision of test is also difficult to guarantee, can has a strong impact on the accuracy of data measured.Therefore, the development of vehicle air suspension system testing table clamping mechanism, just for the design of vehicle air suspension system testing table provides guarantee.
Summary of the invention
Problem to be solved in the utility model is, overcomes the deficiencies in the prior art, and a kind of vehicle air suspension system testing table clamping mechanism is provided, and relevant jig Design technology is applied on vehicle air suspension system testing table.
The utility model solves its technical matters and takes following technical scheme to realize:
A kind of vehicle air suspension system testing table clamping mechanism providing according to the utility model, comprise gantry frame (1), location and guiding mechanism (2), crossbeam (3), connecting trays (4), it is characterized in that: described location and guiding mechanism (2) link together with crossbeam (3), connecting trays (4) links together with crossbeam (3) by location and guiding mechanism (2), and crossbeam (3) links together with gantry frame (1).
Aforesaid vehicle air suspension system testing table main body adopts gantry frame structure.
The utility model compared with prior art has significant advantage and beneficial effect.
The utility model both can carry out the test of single air spring or vibroshock, can complete again the test of whole airsuspension system, owing to having adopted special clamping mechanism, both guaranteed the precision of test simultaneously, and made again whole test process save time, facilitate.
Embodiment of the present utility model is provided in detail by following examples and accompanying drawing thereof.

Embodiment
Below in conjunction with accompanying drawing and preferred embodiment, to the embodiment providing according to the utility model, structure, feature and effect thereof, be described in detail as follows.
Refer to Fig. 1, a kind of vehicle air suspension system testing table clamping mechanism, comprises gantry frame (1), location and guiding mechanism (2), crossbeam (3), connecting trays (4).
Described location and guiding mechanism (2) are that three groups of column type rolling linear guide pin bushing pairs are evenly arranged on the circumference of crossbeam pallet, guarantee spring carried mass vibration in the vertical direction.Rolling linear guide pin bushing pair is made up of straight line (sport ball) bearing and (straight line) cylinder axis.Its structure of linear bearing is that retainer is housed within outer ring, and retainer is equipped with many group axial rolling steel balls, is used in conjunction with for unlimited stroke and cylinder axis.The two ends of retainer are fixed with inner spring back-up ring, are provided with breach window in the rectilinear orbit side of the each group of stressed work of steel ball; This structure guarantees that carrying steel ball and axle do rolling point connect, therefore maneuvering load is little.Steel ball rotates with minimum frictional resistance, thereby can obtain high-precision easy motion, is widely used in precision equipment.When linear bearing is installed, needs and shaft centre line are in line.If axle tilts to insert, ball may come off, or causes retainer modification, thereby linear bearing is caused to damage, plus load should mean allocation on whole bearing, while especially bearing instantaneous load, should use two or more bearings.Linear bearing does not bear rotation load, otherwise may cause mishap.
Described connecting trays (4), is fastened between connecting trays and wheel tray and is led by six roots of sensation guide rod, prevents from producing larger inclination for the spring of simulating vehicle.
Claims (2)
1. a vehicle air suspension system testing table clamping mechanism, comprise gantry frame (1), location and guiding mechanism (2), crossbeam (3), connecting trays (4), it is characterized in that: described location and guiding mechanism (2) link together with crossbeam (3), connecting trays (4) links together with crossbeam (3) by location and guiding mechanism (2), and crossbeam (3) links together with gantry frame (1).
2. according to the vehicle air suspension system testing table clamping mechanism described in right 1, it is characterized in that: described vehicle air suspension system testing table main body adopts gantry frame structure.
