Abstract
The utility model relates to an emergency pump. The emergency pump comprises a pump body, a deflection cam shaft is arranged on the pump body, two plungers are arranged on the deflection cam shaft, each plunger is internally provided with a cylindrical spring, and an oil suction hole is formed in the wall of each plunger; the two plungers are arranged in the plunger holes of the pump body, the plunger holes are communicated with the oil outlets which are communicated with oil outlet pipes, one end of the deflection cam shaft is provided with an oil inlet pipe, and spring pieces and arc-shaped springs are arranged between the oil outlet holes and the oil outlet pipes. The emergency pump provided by the utility model has the advantages of being simple to manufacture, easy to realize precision, and high in positioning precision.
Description
Technical field
The utility model relates to a kind of emergencypump, for gearbox or the transfer case of automobile.
Background technique
In the time that car travels, because of certain particular principles engine misses, the steering pump of automobile runs out of steam source and quits work, and causes hydraulic power steering system to lose turning function, and this is extreme dangerous.At present, the radial plunger on gearbox or the transfer case of automobile is to drive plunger to move up and down by eccentric cam shaft, but its each plunger has the oil suction of one group of spring sheet control pump and fuel-displaced, therefore its complex structure, poor reliability.
Summary of the invention
The purpose of this utility model is in order to overcome above deficiency, and a kind of emergencypump simple, precision easily realizes, positioning precision is high of manufacturing is provided.
The purpose of this utility model is achieved through the following technical solutions: a kind of emergencypump, comprise the pump housing, in the pump housing, be provided with deflection cardiac prominence wheel shaft, deflection cardiac prominence wheel shaft is provided with two plungers, in each plunger, be equipped with cylindrical spring, in each plunger wall, all have oil-sucking hole, two plungers are placed in respectively the plunger hole of the pump housing, plunger hole communicates with oil outlet, oil outlet communicates with oil outlet tube, one end of deflection cardiac prominence wheel shaft is provided with oil inlet pipe, is provided with spring sheet and arc spring between oil outlet and oil outlet tube.
The utility model compared with prior art has the following advantages:
Plunger in the utility model shares two spring sheets, and with the oil suction of control pump and fuel-displaced, therefore it is simple in structure tight rapid, safe and reliable.Emergencypump is because oil-sucking hole is in plunger base, be easy to change oil-sucking hole to plunger base distance, thereby change its output flow, this is that other pumps do not have, and this flow control mode has very large advantage, and very stable of the flow of controlling, along with the rotating speed of emergencypump increases, its output flow does not change substantially, even along with revolution speed increases, its flow also declines to some extent, and this is the needed inviscid flow flow characteristic of steering pump just.It is constant that the flow of this mode control not only has output flow, and have the characteristic that input power is constant, and the energy consumption of pump reduces greatly like this, and the heating of system reduces greatly.Although and its output flow of its steering pump is constant, its input power is non-constant, but along with the rotating speed of pump increases and increases, the power of increase is all converted into heat and has wasted.
accompanying drawing explanation:
Fig. 1 is structural representation of the present utility model;
Number in the figure: the 1-pump housing, 2-deflection cardiac prominence wheel shaft, 3-plunger, 4-cylindrical spring, 5-oil-sucking hole, 6-plunger hole, 7-oil outlet, 8-oil outlet tube, 9-oil inlet pipe, 10-spring sheet, 11-arc spring.
embodiment:
in order to deepen understanding of the present utility model, below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail, and this embodiment only, for explaining the utility model, does not form the restriction to the utility model protection domain.
As Fig. 1 shows a kind of mode of execution of the utility model emergencypump, comprise the pump housing 1, in the pump housing 1, be provided with deflection cardiac prominence wheel shaft 2, deflection cardiac prominence wheel shaft 2 is provided with two plungers 3, in each plunger 3, be equipped with cylindrical spring 4, on each plunger 3 walls, all have oil-sucking hole 5, two plungers 3 are placed in respectively the plunger hole 6 of the pump housing 1, plunger hole 6 communicates with oil outlet 7, oil outlet 7 communicates with oil outlet tube 8, one end of deflection cardiac prominence wheel shaft 2 is provided with oil inlet pipe 9, is provided with spring sheet 10 and arc spring 11 between oil outlet 7 and oil outlet tube 8.
When deflection cardiac prominence wheel shaft 2 rotates, plunger 3 moves up and down, oil sucks by the oil-sucking hole 5 of plunger, discharge by oil outlet 7 after compression, spring sheet 10 covers oil outlet 7 in plunger 3 oil suctions, sucked back to prevent the oil of oil outlet tube 8, spring sheet 10 opens in plunger 3 oil extractions, so that oil is discharged from oil outlet 7.
Plunger in the utility model shares two spring sheets, and with the oil suction of control pump and fuel-displaced, therefore it is simple in structure tight rapid, safe and reliable.Emergencypump is because oil-sucking hole is in plunger base, be easy to change oil-sucking hole to plunger base distance, thereby change its output flow, this is that other pumps do not have, and this flow control mode has very large advantage, and very stable of the flow of controlling, along with the rotating speed of emergencypump increases, its output flow does not change substantially, even along with revolution speed increases, its flow also declines to some extent, and this is the needed inviscid flow flow characteristic of steering pump just.It is constant that the flow of this mode control not only has output flow, and have the characteristic that input power is constant, and the energy consumption of pump reduces greatly like this, and the heating of system reduces greatly.Although and its output flow of its steering pump is constant, its input power is non-constant, but along with the rotating speed of pump increases and increases, the power of increase is all converted into heat and has wasted.
