Abstract

The utility model relates to a test table for testing the performance of a vibration damper of a vehicle. A cross beam of a double upright posts of the test table is arranged on a table board of a machine seat, and the cross beam is connected with two roots of upright posts and can move up and down. The inner part of the machine seat is provided with a supporting base transversely, one end of a shaft of the supporting base is also provided with a crank link mechanism, and the other end is provided with a big belt pulley which is driven by an electric motor. The crank link mechanism which has adjustable stroke can do step or stepless regulation to piston stroke by a hole inserted structure. The speed regulation of the electric motor can be achieved by a speed control assembly with adjustable frequency, and the adding vibration frequency of the test table is changed. The test table has the advantages of adjustable working stroke and adding vibration frequency, high testing precision and high adaptability, and the utility model can meet the requirements of the development of a vibration damper of a vehicle, the production and the use.

Description

Vehicle shock absorber test-bed

The utility model relates to a kind of vehicle shock absorber test-bed

The speed of operation of Hyundai Motor, motorcycle improves day by day.Vibration damper performance requirement to suspension system is also higher, tighter.Therefore, multiple functional, the accurate damper test stand of measurement becomes the essential equipment of development, production high-quality vibration damper.

Existing vehicle shock absorber test-bed oscillating component has hydraulic servo formula and mechanical type two classes.The former structure complexity, cost an arm and a leg, be adapted at the laboratory and use; The latter is simple in structure, cheap, is suitable for the on-the-spot use of factory inspection and Workshop Production.The weak point of existing machinery formula damper test stand is to adapt to the ability of various test specimen types and sample dimensions, installing space and test specimen quantity are restricted, can not stepless speed regulation or accurate control rate, can not do multiple speed trial, adjustment stroke difficulty etc.

It is vehicle shock absorber test-bed that the purpose of this utility model provides a kind of mechanical type, and its function and performance be near the electro-hydraulic servo formula, and cheap, practicality good.

The utility model is made up of following array apparatus:

A two stand column and beam support, its crossbeam is up-down adjustment on demand;

The toggle of a range-adjustable, can realize stroke have the level and step-less adjustment;

A RHVC, but predeterminable velocity amplitude stepless speed regulation, and can realize many speed controls system;

A testing table support, inner traverse toggle.

The utility model has the advantages that: but the crossbeam up-down adjustment can satisfy the test request of different length vibration damper.Have than large space between two columns, many vibration dampers can be installed, applied widely.Existing mechanical testing table or several length of strokes can only be set, though perhaps can step-less adjustment, regulate very inconvenient.This patent adopts the crank jack structure, can establish ten grades of strokes commonly used, can also utilize special-purpose jack to carry out stepless continuous easily and regulate.RHVC can realize the preliminary election of speed, the step-less adjustment and the how fast stepless control of speed, satisfies the requirement of vibration damper high precision, multiple speed test.The utility model advanced technology, precision height, applicability is wide, the ratio of performance to price is high, to the development of ride-control, produce very big practical value is arranged.

Introduce the utility model below in conjunction with accompanying drawing:

Fig. 1 is the sketch of facing of the present utility model.As shown in the figure, tested vibration damper is installed between force cell 3 and piston 4, and, then crossbeam is locked on the column according to test specimen length adjustment crossbeam height.Toggle is horizontally placed in the support.Big belt pulley 10 drives crank 7 and connecting rod 6, piston 5 are done and pumped.

Fig. 2 a is a diagrammatic view from above of the present utility model.As shown in the figure, motor 13 drives small belt pulley 12 and rotates, and drives big belt pulley 10 rotations by vee belt 11.

Fig. 2 b is the RHVC block diagram.As shown in the figure, motor 13 is powered by frequency converter 14, and by control enclosure 16 control motor work.

Fig. 3 is the toggle sketch of the utility model range-adjustable.As shown in the figure, crank 7 is contained on the adjustment disk 8 of jack, by regulating the relative position of crank and adjustment disk, realizes the setting of required path increment, and is screwed.

Fig. 4 is a crank jack synoptic diagram of the present utility model.As shown in the figure, circular socket holes is used to have level to regulate among the figure, and the crescent jack is used for step-less adjustment.
