Abstract
The utility model discloses an engine test bench, which comprises a dynamometer machine, a transmission shaft, an engine, an engine base and a base platform; wherein, the engine is fixed on the base platform by means of the engine base; the output shaft of the engine is connected to the transmission shaft; one end of a flange is connected with the input shaft of the dynamometer machine; the other end is connected with the transmission shaft; the dynamometer machine is mounted in a dynamometer machine base and fixed on the base platform by means of a dynamometer machine supporting frame; and a dynamometer machine excitation control cable, a dynamometer machine monitoring cable, a dynamometer machine rotating speed measuring cable and a dynamometer machine torque measuring cable are connected with corresponding pins on the dynamometer machine. Because the utility model mounts a domestic dynamometer machine on an imported bench and redesigns the ports of the dynamometer machine, including mechanical connection and electric connection, the reliability of the dynamometer machine is equivalent to the original dynamometer machine, while cost is greatly saved and maintenance is convenient.
Description
Technical field
The utility model relates to a kind of test-bed, a kind of specifically test-bed of dynamometer machine being installed and engine performance being tested.
Background technology
At present, the test-bed of the lift-launch electric eddy current dynamometer that the Austrian AVL of widespread usage produces in the factory, its dynamometer machine is all by its subsidiary/member companies---and German Ce Erna company produces.Water jacket size in this dynamometer machine eddy current ring is less than normal relatively, scale problems can occur after long-time the use, and fouling causes the heat radiation of eddy current ring bad, can cause the appearance of seize problem after the ring thermal deformation, in case the whole dynamometer machine of seize just faces the danger of scrapping.Present domestic use all are complete import equipments, after dynamometer machine is scrapped,, obviously have problems such as on the high side, maintenance cost is big, the arrival cycle is long if be replaced with complete equipment.
Summary of the invention
The purpose of this utility model is to overcome the weak point that exists in the above-mentioned technology, a kind of dynamometer test stand reasonable in design, with low cost is provided, can effectively overcomes the threst stand of above-mentioned on the high side, weak points such as maintenance cost big, the arrival cycle is long.
In order to achieve the above object, the technical solution adopted in the utility model is: comprise dynamometer machine, transmission shaft, engine, engine foundation and basic platform, engine is fixed on the basic platform by engine foundation, engine output shaft is connected to transmission shaft, the input shaft of flange one end and dynamometer machine joins, the other end and transmission shaft join, dynamometer machine is installed on the dynamometer machine base, and be fixed on the basic platform by the dynamometer machine support, dynamometer machine excitation control line, the every monitoring cable of dynamometer machine, dynamometer machine tachometric survey line, dynamometer machine torque measurement line links to each other with corresponding pin on the dynamometer machine.
The utility model has the advantages that:
Because the utility model is installed homemade dynamometer machine on the import stand, redesigned the interface with dynamometer machine, comprise mechanical connection and be electrically connected that dependability is suitable with original-pack dynamometer machine, but has saved cost greatly, and easy to maintenance.

Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
By Fig. 1-Fig. 5 as can be known, the utility model comprises dynamometer machine 1, transmission shaft 3, engine 5, engine foundation 4 and basic platform 8, engine 5 is fixed on the basic platform 8 by engine foundation 4, engine 5 output shafts are connected to transmission shaft 3, the input shaft of flange 2 one ends and dynamometer machine 1 joins, the other end and transmission shaft 3 join, dynamometer machine 1 is installed on the dynamometer machine base 6, and be fixed on the basic platform 8 by dynamometer machine support 7, every index monitoring cable, tachometric survey line, torque measurement line and excitation drive wire link to each other with corresponding pin on the dynamometer machine 1.Wherein said dynamometer machine base 6 is made up of upper plate 9 and lower plate 10 and back up pad 11, upper plate 9 is a rectangle, have threaded hole 12 on it, with dynamometer machine 1 corresponding and and dynamometer machine 1 connect, lower plate 10 is a rectangle, have on it threaded hole 13 and dynamometer machine support 7 corresponding and and dynamometer machine support 7 connect, between upper plate 9 and the lower plate 10 by back up pad 11 connections.
This shows, on the import test-bed,, the axis of dynamometer machine 1 output shaft is dropped within the crankshaft center adjustable extent of engine 5 for dynamometer machine 1 redesign mounting seat.Redesign switching flange 2 makes dynamometer machine 1 link to each other with transmission shaft 3 by flange 2, and links to each other with engine 5 by transmission shaft 3.Independent dynamometer machine is consistent at used sensor type aspect torque measurement, tachometric survey, the temperature measurement with the dynamometer machine of former assembling system, but the definition of circuit stitch is different, carries out circuit by the stitch corresponding relation and connects.Cable X3 is a dynamometer machine excitation control line among Fig. 5, and cable X4 is the every monitoring cable of dynamometer machine, and cable X7 is a dynamometer machine tachometric survey line, and cable X8 is a dynamometer machine torque measurement line.
