Description
Technical field
The invention belongs to part of automobile engine, applied to the front end wheel train system with belt start-stop (BSG)
In, and in particular to engine tensioning apparatus.
Background technology
Engine stretching wheel is mainly used in motor front-end wheel system, can be compensated with auto-tensioning front end wheel train belt
Train tolerance and belt elongation percentage, can partially absorb the vibration that crank pulley passes out in engine operation process.It
It is the important parts of automobile, its durability is directly related to the normal work and hair of the parts such as water pump, compressor, generator
The performance of motivation NVH.
As shown in Figure 1 and Figure 2, prior art engine stretching wheel is mainly by cup body 1,1 contained spring component of cup body, tensioning
Wheel bolt 2, tensioner arm 3, belt wheel 4 are formed.Wherein tensioning wheel spring assembly provides a spring torque, passes through tensioner arm 3, belt wheel
4 pairs of front end wheel train belts 14 form a pressure, front end wheel train belt 14 is possessed certain tension force, meet belt transmission need
Ask.When 14 length change of front end wheel train belt or crankshaft vibration, tensioner arm 3 can make entirely to take turns with automatic swing to be tied up to
Possesses relative constancy tensile force in dynamic movement process.
As national oil consumption requirement is more and more stringenter, whether oil consumption meets to determine whether vehicle can continue to sell, so
Reducing complete-vehicle oil consumption becomes the top priority of each main engine plants.48V belts start stop system (BSG) can reduce oil consumption 10% with
On, it is the primary study technology of each main engine plants in China, but it has at the same time by the generator that front end wheel train belt drives
The function of preparation motor and driving motor.48V belts start stop system (BSG) front end wheel train has such as relative to conventional belt transmission
Lower feature：
1. the moment of torsion of front end wheel train belt transmission is big, generator peak torque reaches 50N.m；
2. front end wheel train power transmission is two-way --- power both can be delivered to generator from engine, can also be by
Generator is delivered to engine.
3. the function that front end wheel train can be realized is more more complicated.
Based on background above, the tensioning wheel of the prior art is applied has larger defect in belt start-stop train (BSG), such as schemes
Shown in 2, when generator belt wheel 17 is in generating function, dynamo belt approach section 19 is pilled-in selvedge (relative to dynamo belt
Take turns the belt of other side), dynamo belt deferent segment 18 is slack list, that engine stretching wheel provides for front end wheel train at this time
Power F is the minimum tension force of train system, and front end wheel train system meets service requirement.But when generator belt wheel 17 be in power-assisted or
During start operating performance, dynamo belt approach section 19 is slack list (relative to the belt of generator pulley other side), generator
Belt deferent segment 18 is pilled-in selvedge, and the tension force F that engine stretching wheel provides at this time is the tension force of belt deferent segment 18.It is assumed that motor is turned round
The pressure that square is T17, tensioning wheel provides is F, the tension force of dynamo belt approach section 19 is F19, dynamo belt deferent segment 18
Tension force be F18, generator radius is R, 4 cornerite of belt wheel is γ (γ amplitudes of fluctuation very little), when generator is in power-assisted operating mode
When, there are following relation in theory：
2. F19=F*f (4 cornerite γ of belt wheel)；
②
According to train performance requirement, do not allow belt to there is a situation where 0 tension force, if to ensure F18 >=0N, need to send out
The pressure F that motivation tensioning wheel provides brings up to a very high level.This to generator in front end wheel train, belt, tensioning wheel,
The aging effects of the parts such as water pump are very big.
The content of the invention
Before a kind of tensioning wheel and engine for possessing bidirectional modulation front end wheel train tension function
