Description
Technical field
The present invention relates to technical field of automobile engine, more particularly to a kind of startup dynamo belt transmission device.
Background technology
The drive belt that currently active dynamo belt transmission device includes starter/generator, is located in starter/generator shaft
The crank pulley take turns, being located on bent axle, the driving belt being arranged around driving belt pulley and crank pulley, in order to make transmission
The other side setting stretcher of idle pulley, driving belt is usually arranged in the side of driving belt, is arranged on stretcher for belt tension
Tensioning wheel, when driving belt long-time service is stretched or when driving belt tension reduces, tensioner piston is in lubricating system oil
It is forward extended out under the action of pressure, heads on tensioning wheel and be tensioned driving belt, compensate the elongation of driving belt；When driving belt
When clamp force is excessive, tensioner piston, which inwardly retracts, reduces the tensile force of driving belt, to make driving belt remain at one
In fixed tension range.But the driving belt that stretcher side is only adjusted when adjusting, in the tension of the driving belt of idle pulley side
It can not adjust, and idler side driving belt overtension can influence that the service life of driving belt, tension is too small so that driving belt is beaten
Transmission performance that is sliding and influencing driving belt
Invention content
The technical problem to be solved by the present invention is to：A kind of can automatically adjust to balance of both sides driving belt is provided
Power and the startup dynamo belt transmission device without being externally supplied oil pressure.
