Description
Technical field
The utility model relates to a kind of air-strainer, refers to a kind of air-strainer that is applicable to the locomotive engine gas handling system especially.
Background technique
For general motor vehicle, the side of its engine intake group usually is provided with an air-strainer, and this air-strainer is in order to the filtration ambient air, and after making it become peace and quiet air, more peace and quiet air is imported in the Carburetor of engine.
See also Fig. 1; It is the exploded view of convention air-strainer; The air-strainer 90 that convention speed gram reaches locomotive (SCOOTER-TYPEMOTORCYCLE) is to be combined each other by a left shell 91 and a right shell body 93; In it and group establish a filter element 92, this filter element 92 is by filter paper 94 and a fixed frame 95 secure bond formula structure that becomes one, ambient air is that the suction port 911 via the left shell 91 of air-strainer 90 gets into; Flow through behind the filter paper 94; Via the air outlet 931 of right shell body 93, get in the engine Carburetor of (figure does not show) via a steam outlet pipe 96 again, left shell 91, right shell body 93 are by several bolt 97 sealed air-strainer 90 structures that fixedly become integral type with 92 of filter elements.
Yet the position that is provided with of convention air-strainer 90 all is fixedly arranged between locomotive Transmission Room top and vehicle frame below and storage box left side and the appearance component inboard usually, and convention air-strainer 90 must be dismantled several bolts 97 with instrument when maintenance changes filter paper 94; Take out left shell 91 and filter element 92 more laterally; Because the above-mentioned space of locomotive is limited, so that air-strainer 90 receives many restrictions when configuration, following shortcoming is arranged: because air-strainer 90 is covered in its inboard by appearance component; In maintenance direct demounting bolt 97 during dismounting; That is can't directly take out left shell 91 and filter element 92, and after the maintenance man needs earlier the dismounting appearance component, can demounting bolt 97; Cause maintenance to be difficult for, waste time and energy.In addition, if consider bolt 97 configurations and maintenance dismounting path, then possibly need to reduce the shared space of air-strainer 90; Cause the overall volume of air-strainer 90 too small, can influence air inflow, and then influence engine performance; Be not very good, the space of improvement is still arranged.
The creation popularity originally in the spirit of positive invention, is urgently thought a kind of air-strainer of the locomotive engine gas handling system that can address the above problem because of in this, and several times research experiment is eventually to accomplishing the utility model.
The model utility content
The main purpose of the utility model provides a kind of air-strainer of locomotive engine gas handling system, and the maintenance dismounting path of air-strainer can not blocked by the appearance component of locomotive.Can promote the maintenance disassembly, save manpower and man-hour, and can keep the overall space of air-strainer again, can not influence air inflow, and then influence engine performance.
The air-strainer of the locomotive engine gas handling system of the utility model includes: a hollow casing and a filter element.Wherein, Hollow casing includes a room and an assembling opening in a suction port, the air outlet; Filter element then includes a filter member and in order to set firmly the framework of filter member, and filter element is the detachable interior room that is assembled in hollow casing via the assembling opening of hollow casing.That is, but the filter element of the utility model is that pull takes out by the assembling opening of hollow casing.
Above-mentioned filter member and framework can be the structure of integral type, also can be two formula separated structures, again secure bond and become filter element.
Can have perforation on the framework of above-mentioned filter element, then corresponding on the hollow casing have screw, thereby can the filter element spiral shell be located on the hollow casing by several spiral locks.Again, filter element also can be fixed on the hollow casing by the technological means of engaging or other secure bond.
Above-mentioned hollow casing can include one first housing and one second housing, and first housing and second housing can be the structure of integral type.In addition, first housing and second housing also can be the structure of two formulas, utilize ultrasonic wave welding secure bond to form again.
Above-mentioned filter member can be filter paper or other equivalent filtering material element, can reach the function of filtered air.
The assembling opening of above-mentioned hollow casing can be positioned at the rear side of hollow casing, so that the maintenance dismounting path of filter element is unlikely to be blocked by the appearance component of locomotive side.
The air outlet of above-mentioned hollow casing can be positioned at first housing, and the suction port of hollow casing can be positioned at second housing in addition.In addition, the bottom of second housing can have a leakage hole, can discharge the rainwater that is flowed into by suction port.
The air-strainer of the utility model can be mounted on the Transmission Room top of locomotive engine; Also can be mounted on other place; As long as the assembling opening and the travel path thereof of the hollow casing of air-strainer are not blocked by other member of locomotive, all can reach the effect of the utility model.
The utility model can promote the maintenance disassembly, saves manpower and man-hour, and can keep the overall space of air-strainer again, can not influence air inflow and engine performance.
