Description

The online break-in test of engine chassis

Technical field

The utility model relates to the online break-in mechanism for testing of engine, is specifically related to a kind of test chassis that is used for the online break-in annular of engine fixture system.

Background technology

Engine is the heart of motorcycle, automobile, the performance of motorcycle, motor car engine is except rated power, outside the key indexs such as moment of torsion, oil consumption, pollutant emission, the engine of starting performance, idling performance, noise and band wheel box comprises that also running quality such as clutch, shift are also quite important, major part belongs to the forced examination project of state compulsion authentication (3C authentication), and whether its performance index meet the requirements is related to the motorcycle after dispatching from the factory, the quality safety and the serviceable life of automobile.Therefore, the test that the engine of motorcycle, automobile is carried out break-in and related check project is the necessary operation of manufacturer's manufacturing process.

At present, the break-in of motorcycle, motor car engine test generally adopts elder generation after finishing assembling on the engine line, then it is moved away from assembly line, clamps and carries out running-in test on the break-in frock; After the engine finished product that assembling need be finished unloads from the assembly line anchor clamps like this, forward engine to test site by special-purpose container again, carry out running-in test behind the secondary clamping.So not only increase the workload of a large amount of man-handlings of materials and secondary clamping, inefficiency; And can have in various degree damage unavoidably to the outward appearance of product.And existing break-in mechanism for testing pedestal is mainly two kinds of cement pedestal and whole disk swingings.Obviously the cement base type is not removable, be unsuitable for on-line testing, and cement pedestal shock-absorbing effect is poor, can not the real ruuning situation of simulated engine; Though whole disk swinging pedestal is applicable to on-line testing, because many shared brace foundations of engine form resonance and the phase mutual interference, the accuracy that the influence test is judged easily.

The utility model content

At the prior art above shortcomings, the purpose of this utility model is to provide a kind of and cooperates with engine line, not only solve the man-handling of materials problem, and can the real ruuning situation of simulated engine, improve the test chassis that is used for the online break-in annular of engine fixture system of test accuracy.

The purpose of this utility model is achieved in that the online break-in test of engine chassis, it is characterized in that mainly being made of car body, support castor, driving wheel, electric driver mechanism, stretching pulley and break-in mechanism for testing; The deck plate of car body is provided with the cavity that is used for the jacking of engine anchor clamps.

Support castor and be located at the bottom of four jiaos of car bodies, driving wheel and stretching pulley level are located on the chassis of car body, leave the gap that is used to be provided with drive track between driving wheel and the stretching pulley; The break-in mechanism for testing is located on the car body.

The front side of described car body also is provided with limited block and the position transducer that is used to stop.

Compared to existing technology, the utlity model has following advantage:

1, cooperate with engine line, cancellation transhipment and secondary clamping are enhanced productivity and are saved human resources; Simultaneously, avoided the secondary clamping to damaged products.

2, with similar tire and with the real ruuning situation of the dolly castor simulated motorcycle of damping, a dolly once carries an engine and carries out the break-in test, not only realizes on-line testing but also solved the resonance interference problem, has improved the accuracy of test.

3, adopt the test tracks of annular to cooperate with engine line, testing chassis and testing apparatus utilization factor is 100%, is doubled with respect to the existing in-line online break-in tooling device utilization factor 50% of keeping straight on, and has effectively saved the energy and production site.

4, adopt the test tracks of annular to cooperate with engine line, can effectively solve the insoluble pressurized air retinue of linear on-line testing problem, by the pressurized air ring distributor easily to each test chassis voltage supply air that contracts, the use of clamping robotization and efficient aerodynamic instrument is become a reality, improved production efficiency greatly and reduced labour intensity.

5, test chassis and ground are contour, off-line maintenance easily after breaking down, and it is auxiliary to need not lifting or fork truck.

Embodiment

The utility model is described in further detail below in conjunction with the drawings and specific embodiments.

As Fig. 1, Fig. 2 and shown in Figure 3, the online break-in test of the utility model engine chassis mainly is made of car body 11, support castor 12, driving wheel 13, electric driver mechanism 14, stretching pulley 15 and break-in mechanism for testing; Support castor 12 and be located at the bottom of 11 4 jiaos of car bodies, driving wheel 13 and stretching pulley 15 levels are located on the chassis of car body 1, leave the gap that drive track 8 is set between driving wheel 13 and the stretching pulley 15, (driving wheel 13 and stretching pulley 15 clamp drive track); Electric driver mechanism 14 comprises motor and wheel box, drives driving wheel 13 and moves on annular drive track 8.The deck plate 17 of car body 11 is provided with the cavity 20 that is used for the jacking of engine anchor clamps.

The front side of car body 11 also is provided with limited block and the position transducer 16 that is used to stop.

The break-in mechanism for testing is the same with existing equipment, is provided with detection of engine rated power, starting, idling and acceleration, and commentaries on classics and toxic emission mechanism (omitting among the figure).

Adopt several break-in test chassis of the utility model to be located on the annular Load-bearing rail, break-in test chassis is by annular Load-bearing rail guiding (the annular Load-bearing rail is made of interior rail and outer rail).Support castor 12 and on the annular Load-bearing rail, travel as the engaged wheel of driving wheel 13, on one side the truth of simulated motorcycle operation, the performance of 14 pairs of engines of break-in mechanism for testing is tested simultaneously.

Its principle of work: the engine of finishing assembling is tested on the chassis to break-in by 10 transfers of jacking transfer mechanism from engine line, carry out the robotization clamping by the efficient aerodynamic instrument, the truth of break-in test chassis simulated motorcycle operation on one side, simultaneously, the break-in mechanism for testing is tested the performance of engine; Not only realize on-line testing but also solved the resonance interference problem, improved the accuracy of test.
