Description
Technical field
The present invention relates to automobile engine front end accessory performance test fields, and in particular to a kind of test pulley decoupler
Endurance test bed.
Background technique
With world petroleum resource rapidly deplete and the oil consumption problem of conventional fuel oil car fails effectively to be solved always
Certainly, cause mixed motor-car type increasingly by public concern.Compared with conventional fuel oil car, the oil consumption of mixed motor-car type is substantially reduced,
But due to thering is frequent torque to transmit between mixed motor-car h type engine h crankshaft front end and starting motor, so that mixed motor-car type occurs
More serious NVH problem.Belt pulley decoupler (PYD) is mounted on the crankshaft front end of engine, similar to a small-sized pair
Mass flywheel can effectively obstruct crankshaft and be transmitted to the vibration of accessory system and start the vibration that motor is transmitted to engine crankshaft
It is dynamic.
Being installed on the belt pulley decoupler (PYD) of mixed engine of motor vehicles crankshaft front end, there are mainly two types of operating conditions: the first
It is engine operation, drive starting motor operating charges to battery, and PYD mainly barrier engine crankshaft is transmitted to attached at this time
The vibration of part system；Second of operating condition is starting motor work, and dragging engine operating, PYD mainly obstructs attachment system at this time
System is transmitted to the vibration of engine crankshaft.In mixed motor-car, both operating conditions can be frequently alternately present, and belt pulley decouples at this time
Torsional vibration damper inside device can be reversed back and forth, and two kinds of operating conditions alternately will appear very big punching in vehicle high-speed operating
It hits, therefore the working environment very severe of belt pulley decoupler (PYD), so it is good to need to guarantee that it has in product design
Endurance quality.
Summary of the invention
The present invention provides a kind of testing stand of test pulley decoupler durability, which passes through two motor bands
Dynamic belt pulley decoupler is reversed, and is simulated under the normal work operating condition of PYD with large impact operating condition, is tested its endurance quality.?
Before test, need to match different driving wheel and driving wheel according to the belt pulley decoupler of different model, when nominal situation is tested,
Active motor, which rotates forward, drives belt pulley decoupler to rotate forward, Resistance motor reversion, the moment of resistance needed for being provided by big sticky bearing,
It is run 200 hours under 3000 revs/min of revolving speed, whether observation product occurs to destroy or fail.Large impact high amplitude working condition measurement
When, active motor rotates forward, Resistance motor reversion, controls resistance of the revolving speed of Resistance motor to be changed by controller
The phenomenon that square, belt pulley decoupler shock-absorbing spring just will appear reversed torsion, simulates large impact operating condition with this, transports under this operating condition
Whether 42 hours observation products of row occur to destroy or fail.
