Abstract
The utility model provides a plastic air throttle for an electric spraying fuel oil system of an automotive vehicle, which comprises an air throttle body (1) and is characterized in that a splicing inserted sleeve (11) made of metal materials is embedded at the position of an installation hole of a stepping motor (10) of the air throttle body (1). By means of arrangement of the splicing inserted sleeve, a gap is formed between a splice head and the splicing inserted sleeve of the stepping motor when the air throttle works at idling speed, thereby solving the problems that the size change is large, the precision is lowered and the whole vehicle performance is affected caused by thermal expansion in work of a plastic air throttle in the prior art.
Description
Technical field
The utility model relates to the automotive component technical field, particularly a kind of plastics closure of Motor Vehicle EFI oil-fired system.
Background technique
Closure is the critical component of control engine air air inflow in the Motor Vehicle EFI fuel oil; The throttle body of existing Motor Vehicle EFI oil-fired system generally all be to make with metallic material, but metallic material proportion is bigger; Closure weight is heavier, and the closure fabricating cost is high.Therefore, occurred the plastics closure at present, plastics closure proportion is less; Price is lower, but the plastics closure is under the car load working state, and throttle body heating back is because thermal expansion; Cause the throttle body dimensional changes bigger, precision reduces, thereby influences the car load service behaviour.
The model utility content
The utility model provides a kind of plastics closure of Motor Vehicle EFI oil-fired system, and to solve in the plastics closure of the prior art work because of thermal expansion causes dimensional changes bigger, precision reduces, and influences the problem of vehicle performance.
To achieve these goals, the utility model provides following technological scheme:
A kind of plastics closure of Motor Vehicle EFI oil-fired system comprises tb 1, and the stepper motor mounting hole place of said tb 1 is embedded with the assembly head edge cover of being processed by metallic material 11.
Preferably, said outer rim of piecing together head edge cover 11 is provided with stop breach 111.
Through implementing above technological scheme, have following technique effect: the plastics closure of the Motor Vehicle EFI oil-fired system that the utility model provides, piece together head edge cover through being provided with, when the closure idling work, form the gap between the assembly head of stepper motor and the assembly head edge cover.Solved in the plastics closure of the prior art work because of thermal expansion causes dimensional changes bigger, precision reduces, and influences the problem of vehicle performance, is that a kind of cost is low, reliability is high, the plastics closure of the Motor Vehicle EFI oil-fired system of long service life.
Description of drawings
The structural representation of the plastics closure of the Motor Vehicle EFI oil-fired system that Fig. 1 provides for the utility model embodiment;
The structural representation that the assembly head edge that Fig. 2 provides for the utility model embodiment overlaps.
Embodiment
In order better to understand the technological scheme of the utility model, describe the embodiment that the utility model provides in detail below in conjunction with accompanying drawing.
The utility model embodiment provides a kind of plastics closure of Motor Vehicle EFI oil-fired system, comprises tb 1, and is as shown in Figure 1, and the stepper motor mounting hole place of said tb 1 is embedded with the assembly head edge cover of being processed by metallic material 11.
In other embodiment, further as shown in Figure 2, said outer rim of piecing together head edge cover 11 is provided with stop breach 111.
The plastics closure of this Motor Vehicle EFI oil-fired system is pieced together head edge cover 11 through being provided with, when the closure idling work assembly of stepper motor 10 101 with piece together the head edge and form the gap between overlapping 11.Solved in the plastics closure of the prior art work because of thermal expansion causes dimensional changes bigger, precision reduces, and influences the problem of vehicle performance, is that a kind of cost is low, reliability is high, the plastics closure of the Motor Vehicle EFI oil-fired system of long service life.
More than the plastics closure of a kind of Motor Vehicle EFI oil-fired system that the utility model embodiment is provided carried out detailed introduction; For one of ordinary skill in the art; Thought according to the utility model embodiment; The part that on embodiment and application area, all can change, in sum, this description should not be construed as the restriction to the utility model.
Claims (2)
1. the plastics closure of a Motor Vehicle EFI oil-fired system comprises tb (1), it is characterized in that, stepper motor (10) the mounting hole place of said tb (1) is embedded with the assembly head edge cover of being processed by metallic material (11).
2. the plastics closure of Motor Vehicle EFI oil-fired system according to claim 1 is characterized in that, a said outer rim of piecing together head edge cover (11) is provided with stop breach (111).
