Description
Technical field
The invention belongs to booster arrangement technical fields, are related to a kind of adjustable adjusting rod structure of booster.
Background technique
Booster with bypass system can be increased by bypassing a part of exhaust energy under certain engine operating conditions
Increase former revolving speed surplus, promotes the performance of engine so as to select smaller volute.According to the applying working condition of engine,
The engine calibration being typically different may require that different by-passing valve opening points.Before booster factory, supercharger producer can lead to
The setting pressure of control booster is crossed to meet the by-passing valve opening point of engine calls.
As shown in Figure 1, the booster with bypass system includes adjuster 1, adjusting rod 2, drive rod 3 and by-passing valve control
Bar 4.Adjusting rod 2 is located among adjuster 1 and bypass valve system, and the bar of it and adjuster 1 is generally connected through a screw thread, and bypass
Valve system is connected by drive rod 3 and by-passing valve control-rod 4.When supercharger pressure is set, press device is used first
The pressure for being passed through adjuster 1 is accurately controlled, is equipped with spring inside adjuster 1, spring can compress under stress, then pass through adjusting
Adjusting rod 2 adjusts the displacement that by-passing valve at this pressure is opened.When displacement is unsatisfactory for setting requirements, need to be detached from adjusting
The connection of bar 2 and drive rod 3 changes the length of action of itself and governor lever so as to rotation adjusting lever 2, then again and bypass
Valve drive rod 3 connects, to change the displacement that by-passing valve is opened under this specified pressure.After booster is set, withdraws and be passed through
The gas source of adjuster 1, spring for governor is in confined state at this time.Engine operation when, when be passed into adjuster 1 and
By-passing valve can just be opened when the power summation being applied on bypass valve system is greater than the pretightning force of spring for governor.
From description above, it can be seen that the pressure setting of common booster there is a problem of some apparent.It is first
First, the connection for dismounting adjusting rod 2 and drive rod 3 back and forth is needed when booster is arranged to adjust adjusting rod 2 and to adjust
The length of action of device 1, it is inefficient.Secondly as adjusting rod 2 finally will always be connected with drive rod 3, so adjusting rod 2
Rotation angle can only be 170 degree of integral multiple every time, i.e., at least needing to twist half-turn reach every time, (such as adjusting rod screw pitch is
1.07mm, half-turn reach are 0.54mm, i.e. degree of regulation only has 0.54mm), it otherwise will be unable to connect with drive rod 3, if
It is not high to set precision.There are also fine-tuning adjusting rod structures currently on the market, and setting precision can be improved, but usually relatively more high
It is expensive, and structure is also more complicated needs to occupy biggish space.
Summary of the invention
For the present invention in view of the above-mentioned problems, providing a kind of adjustable adjusting rod structure of booster, the adjusting rod structure precision is high,
Adjust it is high-efficient, can effectively improve booster setting pressure precision.
Technical solution according to the invention: a kind of adjustable adjusting rod structure of booster, including sequentially connected adjuster,
Adjusting rod, drive rod and by-passing valve control-rod, wherein by-passing valve control-rod is set on volute, it is characterised in that: the adjusting
Also set up adapter between device and adjusting rod, the extension bar of adapter axial direction one end and adjuster is threadedly engaged connection, turns
The axial other end of connector and the threaded portion of adjusting rod connect.
As a further improvement of the present invention, adapter internal screw thread is arranged in one end of the adapter, and other end setting turns
Connector external screw thread；The extension bar of the adapter internal screw thread and adjuster is threadedly engaged connection, adapter external screw thread and adjusting rod
Threaded portion connection.
As a further improvement of the present invention, the threaded portion of the adjusting rod is the tune for being formed in adjusting rod axial hole inner wall
Pole internal screw thread, adjusting rod internal screw thread are threadedly engaged with adapter external screw thread.
As a further improvement of the present invention, the threaded portion of the adjusting rod is to be fixed on adjusting rod axial hole outer end face
Nut, nut are threadedly engaged with adapter external screw thread.
As a further improvement of the present invention, correspond on the adapter and one section is arranged at the externally threaded root of adapter
The diameter of polished rod, polished rod is greater than the externally threaded diameter of adapter.
The technical effects of the invention are that: product of the present invention is structurally reasonable ingenious, can be realized booster setting pressure
Unlimited fine adjustment function, and structure is simple, it is easy to operate, it is low in cost, the precision of booster setting pressure can be effectively improved.

Specific embodiment
A specific embodiment of the invention is further described with reference to the accompanying drawing.
In Fig. 1 ~ 5, including spiral shell in adjuster 1, adjusting rod 2, drive rod 3, by-passing valve control-rod 4, adapter 5, adapter
Line 5-1, adapter external screw thread 5-2, polished rod 5-3, nut 6, volute 7 etc..
As shown in Fig. 2 ~ 5, the present invention is a kind of adjustable adjusting rod structure of booster, including sequentially connected adjuster 1,
Adjusting rod 2, drive rod 3 and by-passing valve control-rod 4, wherein by-passing valve control-rod 4 is set on volute 7, the adjuster 1 and tune
Adapter 5 is also set up between pole 2, the axial one end of the adapter 5 is threadedly engaged with the extension bar of adjuster 1 to be connect, and is transferred
The first 5 axial other end is connect with the threaded portion of adjusting rod 2.
Adapter internal screw thread 5-1 is arranged in one end of adapter 5, and adapter external screw thread 5-2 is arranged in the other end；The adapter
Internal screw thread 5-1 is threadedly engaged with the extension bar of adjuster 1 and connect, and the threaded portion of adapter external screw thread 5-2 and adjusting rod 2 connects
It connects.
It is understood that the threaded portion of adjusting rod 2 there are many set-up mode, is shown below two kinds in the present invention:
As shown in Figure 2,3, the first embodiment of the invention: the threaded portion of adjusting rod 2 is to be formed in 2 axial hole of adjusting rod
The adjusting rod internal screw thread 2-1 of wall, adjusting rod internal screw thread 2-1 are threadedly engaged with adapter external screw thread 5-2.
When supercharger pressure is arranged, adapter internal screw thread 5-1 is connected with the external screw thread of 1 extension bar of adjuster, adapter
External screw thread 5-2 is connected with adjusting rod internal screw thread 2-1, screw thread mesh volume is controlled by rotation adapter 5, so as to realize fine tuning
