Abstract
The utility model discloses a kind of middle case for specific nozzle control system, comprise middle case body, be arranged on the rocking arm positive stop lug boss of described middle case body upper part, be arranged on the fan-shaped boss of described rocking arm positive stop lug boss side, and be arranged on the rocker arm body on described fan-shaped boss; Described rocking arm positive stop lug boss is provided with the caging bolt for limiting rocking arm rotation angle; One end of described fan-shaped boss is integrated with described rocking arm positive stop lug boss and is connected; With the center of described middle casing for the center of circle, the central angle of described fan-shaped boss is 1-40 °.The beneficial effects of the utility model: the middle case of the specific nozzle control system that the utility model provides; the mounting point of rocker arm body can change relative to the setting angle of turbine case according to middle case; can be installed on the arbitrary position of fan-shaped boss; can adapt to different vehicle refitting demands, save the design cost of mould greatly.
Description
Technical field
The utility model relates to a kind of middle case for specific nozzle control system.
Background technique
At present, turbosupercharger is the important component of of Modern Engine, and in order to meet the installation requirements of different motors, middle case can change according to the requirement of motor usually relative to the setting angle of turbine case.And the middle case very important component that are turbosupercharger, not only play the effect connecting turbine case and compressor casing, also play the effect of Control Nozzle ring portion.The turbosupercharger of what the motor that domestic at present 8-13 rises used is mostly second generation bypass valve type, but if need upgrading, adopt the turbosupercharger of third generation variable cross section, just need the middle case adopting this specific nozzle control system.
The core institution of third generation variable-area turbocharger---nozzle ring, is fixed on above turbine case, but the rocker arm body of Control Nozzle ring is mounted on middle case.If middle case there occurs change relative to the setting angle of turbine case, change will be ensued in the position of the rocker arm body so on middle case.
Model utility content
The utility model object is that the defect existed for prior art provides a kind of middle case for specific nozzle control system.
The utility model for achieving the above object, adopt following technological scheme: a kind of middle case for specific nozzle control system, comprise middle case body, be arranged on the rocking arm positive stop lug boss of described middle case body upper part, be arranged on the fan-shaped boss of described rocking arm positive stop lug boss side, and be arranged on the rocker arm body on described fan-shaped boss; Described rocking arm positive stop lug boss is provided with the caging bolt for limiting rocking arm rotation angle; One end of described fan-shaped boss is integrated with described rocking arm positive stop lug boss and is connected; With the center of described middle casing for the center of circle, the central angle of described fan-shaped boss is 1-40 °.
Further, described rocker arm body passes the guide hole on described fan-shaped boss by set pin sleeve, and is connected with the shift fork one at the described middle case body back side.
The beneficial effects of the utility model: the middle case of the specific nozzle control system that the utility model provides; the mounting point of rocker arm body can change relative to the setting angle of turbine case according to middle case; can be installed on the arbitrary position of fan-shaped boss; can adapt to different vehicle refitting demands, save the design cost of mould greatly.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Embodiment
A kind of middle case for specific nozzle control system as shown in Figure 1, comprise middle case body 1, be arranged on the rocking arm positive stop lug boss 2 on described middle case body 1 top, be arranged on the fan-shaped boss 3 of described rocking arm positive stop lug boss 2 side, and be arranged on the rocker arm body 5 on described fan-shaped boss 3; Described rocking arm positive stop lug boss 2 is provided with the caging bolt 22 for limiting rocking arm rotation angle; One end of described fan-shaped boss 3 is integrated with described rocking arm positive stop lug boss 2 and is connected; With the center of described middle casing 1 for the center of circle, the central angle of described fan-shaped boss 3 is 1-40 °.
Wherein, described rocker arm body 5 by set pin sleeve through the guide hole 4 on described fan-shaped boss 3, and with described middle case body 1) the shift fork one at the back side is connected.Can allow the installation better effects if of rocker arm body 5 like this, stability is higher, can meet motor completely to turbosupercharger installation requirement at any angle.
Further research is known, and rocker arm body 5 passes the guide hole 4 on corresponding described fan-shaped boss 3 by set pin sleeve, and is connected with the shift fork one at described middle case body 1 back side.The installation stability of rocker arm body 5 can be made so better.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
