Description
Technical field
The utility model relates to a kind of automotive engine air intake system parts, particularly a kind of mechanical electric injecting air damper body with position limiting convex ring.
Background technique
The throttle body mainly mechanical type air throttle body of current domestic low and middle-grade automobile electronic fuel oil jet oil-fired system, its gas handling system mainly drives swing frame assembly to rotate by the motion controlling acceleration cable, throttle valve axle and throttle blade are rotated, and by position transducer, the opening amount signal of throttle blade are exported to automobile electronic fuel oil jet system central unit ECU.ECU is according to vehicle working condition and sensor signal, the oil spout of prompting oil sprayer, gasoline and air is made to be able to abundant mixing, reach best chemically correct fuel, make gasoline Thorough combustion, the content of the toxic gas such as CO and oxynitrides in vehicle exhaust when reducing idling operation, so throttle body is the key components and parts controlling engine charge in automobile fuel injection system.When existing throttle body is connected with air induction hose, it is short that its connecting length has length to have, and can not reach Best link length.
Model utility content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of mechanical electric injecting air damper body with position limiting convex ring, and solving its connecting length when existing throttle body is connected with air induction hose has and long have short, cannot reach the defect of Best link length.
The purpose of this utility model is achieved through the following technical solutions: a kind of mechanical electric injecting air damper body with position limiting convex ring, comprises tb, swing frame assembly, support, torsion spring, throttle plate pin, throttle blade, stepper motor, position transducer and needle bearing.Tb is provided with position transducer fitting seat and stepper motor fitting seat, the inlet end external cylindrical surface of tb is provided with position limiting convex ring, throttle plate pin is arranged on tb by needle bearing, the front end of throttle plate pin is connected on position transducer, position transducer is arranged on the position transducer fitting seat of tb, the rear end extension of throttle plate pin is stretched out outside tb, extension extension is provided with successively torsion spring and swing frame assembly, throttle blade is arranged on throttle plate pin by screw, stepper motor is arranged on stepper motor fitting seat, support installing is on tb.
As preferably, the bulge loop quantity on described tb inlet end external cylindrical surface is 4, and discontinuous at grade symmetrical.
The beneficial effects of the utility model are: on the inlet end external cylindrical surface of tb, be provided with position limiting convex ring, when to inlet end external cylindrical surface socket air induction hose, position limiting convex ring can play position-limiting action, guarantees that the air induction hose length being connected to body inlet end is consistent and best.

Embodiment
Below in conjunction with accompanying drawing, the technical solution of the utility model is described in further detail, but protection domain of the present utility model is not limited to the following stated.
As shown in Figure 1, Figure 2, Figure 3, Figure 4, with a mechanical electric injecting air damper body for position limiting convex ring, comprise tb 1, swing frame assembly 2, support 3, torsion spring 4, throttle plate pin 5, throttle blade 6, stepper motor 7, position transducer 8 and needle bearing 12.Tb 1 is provided with position transducer fitting seat 9, stepper motor fitting seat 10, the inlet end external cylindrical surface of tb 1 is provided with position limiting convex ring 11, throttle plate pin 5 is arranged on tb 1 by needle bearing 12, the front end of throttle plate pin 5 is connected on position transducer 8, position transducer 8 is arranged on the position transducer fitting seat 9 of tb 1, the rear end extension of throttle plate pin 5 is stretched out outside tb 1, extension extension is provided with successively torsion spring 4 and swing frame assembly 2, throttle blade 6 is arranged on throttle plate pin 5 by screw, stepper motor 7 is arranged on stepper motor fitting seat 10, support 3 is arranged on tb 1.Bulge loop 11 quantity on described tb 1 inlet end external cylindrical surface is 4, and discontinuous at grade symmetrical.When the inlet end of tb 1 is connected with air induction hose, can determine that air induction hose is connected to the position on tb 1 inlet end by 4 bulge loops, thus ensure that the air induction hose length connected is consistent and best.
The above is only preferred implementation of the present utility model, be to be understood that the utility model is not limited to the form disclosed by this paper, should not regard the eliminating to other embodiment as, and can be used for other combination various, amendment and environment, and can in contemplated scope described herein, changed by the technology of above-mentioned instruction or association area or knowledge.And the change that those skilled in the art carry out and change do not depart from spirit and scope of the present utility model, then all should in the protection domain of the utility model claims.
