Abstract
The utility model relates to a rotor disk apparatus with adjustable rotary inertia for an electric eddy current retarder testbed, which is composed of a main shaft that is installed on a bracket assembly, a large movable pulley, a middle movable pulley, a small movable pulley and three fixed pulleys, wherein the fixed pulleys are assembled on the main shaft through keys and rotate as the main shaft all the time, and the movable pulley is assembled on the main shaft through two deep groove ball bearings. The movable pulley can not rotate as the main shaft so long as the movable pulley is slightly fixed at ordinary time. When inertia on the main shaft needs to be increased for test, the movable pulley can be fixed together with the fixed pulley and rotate as the main shaft only through fixing the movable pulley together with the fixed pulley. Therefore, the purpose of increasing or reducing the rotary inertia on the main shaft can be conveniently achieved, and the testbed can avoid frequent disassembly and assembly in order to adjust the inertia of fly wheels. The rotor disk structure with adjustable inertia can simulate the inertia of vehicles with different tonnage, has the advantages of simple structure, convenient adjustment, reliable loading and wide applicability, and can be used for an analog loading device of a performance test bed of electric eddy current retarder or a hydrodynamic retarder.
Description
Technical field
The utility model relates to automobile auxiliary braking assembly testing equipment, refer in particular to the rotor disk device of the adjustable moment of inertia of a kind of Electromagnetic Eddy Current Retarder, the load that is applied to the retarder for vehicles bench test of all kinds and specification loads, the kinetic energy that travels of the vehicle during can more realistic simulation various tonnage car decelerations braking.
Background technology
Increase along with driving power, the speed of a motor vehicle and the load of Hyundai Motor, the load of wheel drag further strengthens, people pay attention to security, its usage economy, comfortableness and the feature of environmental protection of automobile in addition, and domestic automobile circle that acts on of retarder begins to come into one's own.But retarder for vehicles still is in the starting stage in China's development, production and application.
As the means of check retarder properties of product, domestic in recent years have producer to develop the retarder testing table.The retarder testing table is mainly used motor-driven, adopts the rotor rotated dish to come the kinetic energy that travels of simulated automotive usually, and the retarder of testing is loaded.But, can not accurately simulate various types of automobile inertia because the moment of inertia of rotor disk can not change.When testing the retarder of different size specifications, often need to regulate moment of inertia at every turn, when the different rotor dish is installed, need to dismantle the whole test platform like this by increase and decrease rotor disk number.Because the rotor disk quality is bulky, dismounting, that fitting operation gets up is very inconvenient, often needs to use lifting machine.
Summary of the invention
The purpose of this utility model proposes the rotor disk device of the adjustable moment of inertia of a kind of Electromagnetic Eddy Current Retarder, translational energy and rotational energy when the kinetic energy simulation that stores when utilizing it to rotate tries automobile brake, running car kinetic energy during the simulated automotive retarding braking more practically loads the retarder for vehicles of all kinds and specification.
The technical scheme that realizes above-mentioned purpose is:
Be provided with the stationary installation of forming by main shaft and a plurality of fixed wheel, it is characterized in that being provided with adjustable apparatus, it comprises big driving wheel, middle driving wheel, little driving wheel, wherein driving wheel and fixed wheel are fixed through securing member, formed the adjustable rotor disk of inertia, fixed wheel is assemblied on the main shaft by connector, and each driving wheel is assemblied on the main shaft by bearing.
Characteristics of the present utility model:
Rotor disk is simple and reasonable, regulates moment of inertia according to the test needs, simulates the kinetic energy that travels of various tonnage automobiles, and retarder is made up loading.It is very convenient simple to adjust rotor disk inertia, need not to dismantle other parts of testing table, need not to use lifting machine just can finish loading tasks; The adjusting time only needs a few minutes, has saved a large amount of manpower and materials.
Description of drawings
The adjustable rotor disk version of Fig. 1 inertia
Embodiment
Describe this use is novel in conjunction with Fig. 1, form by three equirotal fixed wheel A3, fixed wheel B6, fixed wheel C8 and three different big driving wheel 4, middle driving wheel 7, petty action wheels 5 of inertia at the rotor disk of the combination of the employing shown in Fig. 1 inertia form.Fixed wheel is assemblied on the main shaft 2 by key 1 and rotates together all the time, and each driving wheel then is assemblied on the main shaft 2 by two deep groove ball bearings 9, takes out trip bolt 10 at ordinary times, and driving wheel and fixed wheel are not fixed together, and driving wheel does not rotate with main shaft with regard to freely rolling; When testing the moment of inertia that needs to increase on the main shaft 2, only need certain driving wheel and fixed wheel are fixed together by screw 10, this driving wheel has been realized the purpose of inertia on the increase and decrease main shaft just with main shaft 2 rotations.
The moment of inertia of three fixed wheels 3,6,8 is 10kgm among Fig. 1
2, the base inertia on the main shaft 2 is 30kgm like this
2Little, in, the inertia of big driving wheel 5,7,4 is respectively 30,50,70kgm
2Can realize as required that like this inertia is regulated on the main shaft, as shown in table 1.
The adjusting of moment of inertia on table 1 main shaft
