Abstract
The invention discloses an ABS oil pump for a two-wheel locomotive, and belongs to the technical field of oil pumps. The ABS oil pump comprises a pump core (1), a first-class one-way valve (2), a second-class one-way valve (3) and a second oil duct (5), wherein the pump core (1) is connected with the first-class one-way valve (2) through a first oil duct (4), the second oil duct (5) is connected between the first-class one-way valve (2) and the second-class one-way valve (3), the second oil duct (5) is perpendicular to the first oil duct (4), and throttle valves are respectively connected to the first-class one-way valve (2) and the second-class one-way valve (3). The ABS oil pump has the beneficial effects that the ABS oil pump has a favorable flow regulation characteristic, and according to different locomotive types, the size of throttling orifices of the throttle valves can be regulated for specifically preventing the phenomenon that a driver can feel opposite acting force from a brake handle; the oil pump is small in size and light in weight.
Description
Technical field
The present invention relates to a kind of ABS oil pump for two-wheeled locomotive, belong to oil pump technology field.
Background technology
On the two-wheeled locomotive that ABS is installed, in the time that brake hard ABS maintains brake pressure in critical value, have partial pressure and feed back on locomotive brake master cylinder by scavenge oil pump; Driver can experience an opposition from brake handle in this case, " the braking hired roughneck " that namely we are commonly called as. For fear of this situation, people have respectively installed a check valve in the both sides of pump core, by regulating the throttle orifice of check valve to limit the appearance of hired roughneck's phenomenon. But traditional check valve is arranged on pump core position, and processing space is little, and allowance is limited, cause processing to have certain difficulty. Meanwhile, this processing mode can cause oil pump volume too fat to move, and cost rises, and does not also meet the portable and smart total arrangement of two-wheeled locomotive.
Summary of the invention
The problem existing for above-mentioned prior art, the invention provides a kind of ABS oil pump for two-wheeled locomotive, reduces the volume of oil pump and reduces processing cost.
To achieve these goals, the technical solution used in the present invention is: a kind of ABS oil pump for two-wheeled locomotive, comprises pump core, one-level check valve and two-stage unidirectional valve; Pump core is connected by the first oil duct with one-level check valve, also comprises the second oil duct being connected between one-level check valve and two-stage unidirectional valve, and the second oil duct, perpendicular to the first oil duct, is connected with respectively choke valve on described one-level check valve and two-stage unidirectional valve.
Further, in the groove of described pump core, be arranged with sealing ring.
Preferably, described one-level check valve and choke valve are integrated valve block; Two-stage unidirectional valve and choke valve are integrated valve block.
The invention has the beneficial effects as follows: the present invention has good flow-adjusting characteristics, can be according to different automobile types, regulate choke valve throttle orifice size to solve targetedly " hired roughneck " phenomenon; The small volume and less weight more of oil pump volume, meanwhile, has also reduced processing cost.
Brief description of the drawings
Fig. 1 is structural representation of the present invention.
In figure: 1, pump core, 2, one-level check valve, 3, two-stage unidirectional valve, 4, the first oil duct, 5, the second oil duct, 6, sealing ring, 7, choke valve.
Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.
As shown in Figure 1: the present invention includes pump core 1, one-level check valve 2 and two-stage unidirectional valve 3; Pump core 1 is connected by the first oil duct 4 with one-level check valve 2, also comprise the second oil duct 5 being connected between one-level check valve 2 and two-stage unidirectional valve 3, the second oil duct 5, perpendicular to the first oil duct 4, is connected with respectively choke valve 7 on described one-level check valve 2 and two-stage unidirectional valve 3.
In the groove of described pump core 1, be arranged with sealing ring 6.
Described one-level check valve 2 is integrated valve block with choke valve 7; Two-stage unidirectional valve 3 is integrated valve block with choke valve 7.
Pump core of the present invention 1 top has redesigned an oil duct, i.e. the second oil duct 5 moves to the second oil duct 5 by two-stage unidirectional valve 3 by traditional side design. Functional and the reliability that has so not only ensured one-level check valve 2 and two-stage unidirectional valve 3 is unaffected, and being used in conjunction with of check valve and choke valve 7 more makes oil pump have good flow-adjusting characteristics; Can be according to different automobile types car type, adjusting joint discharge orifice size solves " hired roughneck " phenomenon targetedly; Meanwhile, such design makes to process convenient, has reduced processing cost. Meanwhile, compared with traditional oil pump, oil pump volume of the present invention small volume and less weight more, is adapted at installing and using on two-wheeled locomotive.
