Abstract
The utility model relates to a double pipeline aluminium alloy automobile braking pump, which is characterized in that the double pipeline aluminium alloy automobile braking pump is provided with two oil inlet pipelines, two oil outlet pipelines and two piston assemblies. A casing is made from cast aluminum alloy. The utility model can realize oil inlet and oil outlet by double pipelines. Even if one pipeline generates faults, the other pipeline can also continuously work, the braking can normally proceed, and thereby, the safety of running vehicles can be ensured. In addition, because the casing is made from aluminum alloy material, the utility model has light weight, and the machining accuracy is enhanced largely.
Description
The utility model is a kind of braking device, exactly is a kind of dual circuit aluminium alloy automobile brake pump that is exclusively used on the automobile.
Present widely used automobile brake pump is a single tube road cast iron automobile brake pump, promptly be a pipeline oil-feed, a pipeline oil-out cast iron brake pump, its major defect is, an oil circuit goes wrong, brake malfunctioningly immediately, and then cause traffic accident, again since in the existing technology automobile brake pump by iron casting, shortcomings such as event has weight big, and working accuracy is low.
The purpose of this utility model is at the defective in the above-mentioned prior art, for people provide a kind of dual circuit aluminium alloy automobile brake pump.
The utility model is by push rod 15, housing 1, piston component 26,28, in the oil inlet 6,11, fuel-displaced pipeline 10,4, compositions such as pull back spring 27,18, its technical essential is: piston is divided into former and later two piston components, the front end of each piston all is processed into four oil throughs 17,22, and the front end of each piston all is equipped with a pull back spring; Chargine line is divided into preceding chargine line, back chargine line two parts, and a fuel feed hole 29 and a deflation hole (compensation orifice) 16 are all arranged in each pipeline; Fuel-displaced pipeline is divided into preceding fuel-displaced pipeline, the fuel-displaced pipeline two parts in back, and the delivery valve in each hole 3 is normally offs, and housing is made by cast aluminium alloy, and in the bottom of housing, a stop screw 20 is housed; The front end of front piston should be L1=1～2mm apart from the distance of deflation hole, and the front end of rear piston should be L2=2～3mm apart from the distance of deflation hole.
The utility model can realize that dual circuit oil-feed and dual circuit are fuel-displaced after realizing, both has been to have a pipeline fault to occur and malfunctioning, and another pipeline can also work on, and drag is normally carried out, and then has ensured the safety of driving vehicle.In addition since the material of housing we selected cast aluminium alloy for use, not only weight has alleviated widely, working accuracy also is greatly improved.Description of drawings:
Fig. 1 is a cross-sectional view of the present utility model.
