Description
Technical field
The present invention relates to the fields of ESC-HCU actuator, and in particular to a kind of upper cover of automobile ESC plunger pump.
Background technique
ABS is anti-locking system for car, and ESC is automobile electronic stabilization system.As illustrated in fig. 1 and 2, existing plunger pump structure
Composition: plunger guide bush 1, oil outlet 2, reset spring A3, former pump seat of piston pump 4, reset spring B5, sealed steel ball 6.Existing plunger
Pump 4 structure of pump seat specifically includes that pump seat spring(-supported) mount 401, former oil groove 410, former oil outlet A421, former oil outlet B422, the original crossed go out
Oilhole C423, oil duct A431, oil duct B432, oil duct C433.Pump seat of piston pump 4 forms system by being interference fitted with plunger guide bush 1
Hydrodynamic runner.Hydraulic medium brake fluid generates certain pressure under the action of piston plunger, meets and exceeds starting pressure when hydraulic
Power, reset spring A3 action compresses, sealed steel ball 6 is mobile, and valve port is opened, and holds where hydraulic medium brake fluid from reset spring B5
Cavity where intracavitary inflow reset spring A3.Hydraulic medium a part simultaneously flows out to former oil outlet A421 by former oil groove 410 of crossing,
Another part flows out to former oil outlet B422, former oil outlet C423 by oil duct A431, oil duct B432.
In order to reduce influence of the motor pump surging to hydraulic system, in existing plunger pump technique scheme usually at oil outlet
Throttle orifice is set.Oil duct A431 in existing pump seat of piston pump 4, oil duct B432, oil duct C433 should play throttling action.But
It is directly connected to due to crossing oil groove 410 and oil outlet A421, oil duct A431, oil duct B432, oil duct C433 do not play throttling action, leads
It causes existing motor-mount pump pulsating quantity excessive, influences system stability and reliability.
Summary of the invention
It is an object of the invention to overcome the shortcomings of the prior art, and provide a kind of the upper of automobile ESC plunger pump
Lid.
The object of the present invention is achieved by the following technical solutions: the upper cover of this automobile ESC plunger pump, mainly
It including pump seat of piston pump, crosses oil groove A, cross oil groove B, oil outlet A, oil outlet B, oil duct D, oil duct E, be pump among pump seat of piston pump
Seat spring(-supported) mount was symmetrically arranged with oil groove A on pump seat spring(-supported) mount excircle, enabled when valve port is opened, hydraulic medium system of crossing oil groove B
Hydrodynamic from oil groove A, cross oil groove B flow into, cross oil groove A and cross oil groove B the same direction of rotation in outer be separately connected oil duct D and oil duct
The other end of the one end E, oil duct D and oil duct E are separately connected oil outlet B and oil outlet A.The oil duct D is that width was less than oil
The enabled throttling of the arc section groove of slot A, the oil duct E are the enabled throttling of arc section groove that width was less than oil groove B.
The oil outlet A and oil outlet B be symmetrical, and both line with cross oil groove A and mistake oil groove B is wired to
90°。
The invention has the benefit that the present invention changes original flow passage structure, increase throttling oil duct, by pump seat oil duct into
Row throttling plays a role throttling oil duct really；Easy to process, it is more reasonable to be distributed, and restriction effect is more obvious；Reduce liquid
The pulsation of pressure system, eliminates bad noise, improves assembly product stability, bring better usage experience to client.

Specific embodiment
Below in conjunction with attached drawing, the present invention will be described in detail:
Embodiment: as shown in attached drawing 3-4, the upper cover of this automobile ESC plunger pump mainly includes pump seat of piston pump 7, mistake
Oil groove A511, oil groove B512, oil outlet A521, oil outlet B522, oil duct D531, oil duct E532 are crossed, is among pump seat of piston pump 7
Pump seat spring(-supported) mount 401, was symmetrically arranged with that oil groove A511, to cross oil groove B512 enabled when valve port is opened on 401 excircle of pump seat spring(-supported) mount
Qi Shi, hydraulic medium brake fluid are flowed into from oil groove A511, excessively oil groove B512.The outer for crossing oil groove A511 and oil groove B512 excessively is same
Direction of rotation is separately connected oil duct D531 and the one end oil duct E532, and the other end of oil duct D531 and oil duct E532 are separately connected fuel-displaced
Mouth B522 and oil outlet A521.The oil duct D531 is the enabled throttling of arc section groove that width was less than oil groove A511, institute
The oil duct E532 stated is the enabled throttling of arc section groove that width was less than oil groove B512.
Oil outlet A521 and oil outlet B522 are symmetrical, and both line and oil groove A511 excessively and oil groove B512 excessively
Line it is in 90 °, balance runner setting reduces hydraulic system pulsation, eliminate bad noise.
When the invention works: hydraulic medium brake fluid is after piston plunger pressurizes, and sealed steel ball 6 is mobile, seal chamber valve port
It opens, cavity where flowing into reset spring A3 in cavity where hydraulic medium brake fluid from reset spring B5, passes through oil groove from stream
A511, oil groove B512 is crossed, flows into oil duct D531, oil duct E532, after oil duct D531, oil duct E532 play throttling action, braking is situated between
Matter is passing through oil outlet A521, oil outlet B522.
It is understood that it will be understood by those skilled in the art that being subject to technical solution of the present invention and inventive concept
It all should fall within the scope of protection of the appended claims of the present invention with replacement or change.
