Description
Technical field
The present invention relates to a kind of hydraulic pressure adjusting device.
Background technology
The existing hydraulic brake system that is used for walking along the street machinery (as automobile) has electronic type anti-lock brake system and mechanical type anti-lock brake system.There are the following problems for the electronic type anti-lock brake system: the one, can not shorten stopping distance, particularly the glancing impact stopping distance that also can extend on the little road surface of friction coefficient; The 2nd, when the electronic type anti-lock brake system starts the vehicle body shake bigger, the resonance effect when having increased the weight of car brakeing; The 3rd, the complicated electric-control system of a cover is arranged, installation, maintenance difficulty and costing an arm and a leg.The mechanical type anti-lock brake system is compared its low price with the electronic type anti-lock brake system, has been simplified system, but glancing impact allows braking fluid earlier by rubber bodies and make its output of expanding, sacrifice braking force, can not shorten stopping distance, can not realize the anti-lock function.
Summary of the invention
The object of the present invention is to provide a kind of hydraulic pressure adjusting device rational in infrastructure, convenient for installation and maintenance.
The object of the present invention is achieved like this: a kind of hydraulic pressure adjusting device is characterized in that: comprise valve seat, valve gap, end cap, adjustable ring, pressure regulating valve, non-return seat, non-return cap, boiler check valve, adjustment nut lid, first spring, second spring, the 3rd spring; Described valve seat, valve gap, end cap connect into an assembly cavity in turn, and this chamber is simultaneously also as the asphalt channel of braking fluid; Described pressure regulating valve places valve seat, the valve gap linkage section of assembly cavity; Described non-return cap sleeve and places valve gap, the end cap linkage section of assembly cavity on the non-return seat, described non-return cap crown has oil through; Non-return seat periphery has aperture; Described adjustment nut lid is connected with the described pressure regulating valve port that is positioned at the valve seat cavity; Described the 3rd spring places in the cavity between described adjustment nut lid and the valve seat; Described boiler check valve places described pressure regulating valve and adjustment nut to cover in the cavity that surrounds, and described second spring places between boiler check valve and the adjustment nut lid; Described adjustable ring is arranged at the outer shroud week of described valve seat; The sidewall of described pressure regulating valve has the through hole that communicates with its cavity, and this through hole also communicates with the cavity that described valve seat, pressure regulating valve, valve gap surrounded; Have the through hole that communicates with the passage of institute adjustable ring with the contacted described valve seat sidewall of described adjustable ring, this through hole also communicates with the cavity that described valve seat, pressure regulating valve, valve gap surrounded.
Between above-mentioned end cap and the valve gap, between described valve gap and the described valve seat, be between described adjustment nut lid and the described pressure regulating valve and be threaded, be provided with like this and be convenient to installation, maintenance.
One end of above-mentioned pressure regulating valve is umbrella, the cone portion of this umbrella places in the cavity that described valve seat and valve gap surround, its conical surface relies on the port of valve seat, and the trunk portion of this umbrella places in the passage of described valve gap, leaves the gap between the cylinder of cylinder and the vias inner walls of valve gap; The trunk portion of described boiler check valve places in the duct of described pressure regulating valve trunk portion.
The outer shroud Zhou Bingneng that above-mentioned adjustable ring is placed in described valve seat makes circular movement along the outer shroud week of valve seat.
The central axis of above-mentioned end cap and the central axis of described adjustable ring are perpendicular.Be provided with like this be convenient to adjustable ring with being connected of brake cylinder, and can rotate adjustable ring easily the through hole on the valve seat is communicated with the passage of adjustment.
Between above-mentioned adjustment nut lid and the described pressure regulating valve, between described pressure regulating valve and the described valve seat, be provided with seal ring between described adjustable ring and the described valve seat.
Above-mentioned seal ring is the O RunddichtringO.
The purpose that seal ring is set is to prevent to brake the leakage of fluid.
Principle of work of the present invention is: when the less braking force of needs, the pressure zone of braking fluid by forming by end cap, valve gap, non-return cap, non-return seat, first spring, braking fluid enters the valve gap passage through the oil through of non-return seat ring week and non-return cap crown portion, and in pressure regulating valve and valve gap path clearance flow into the cavity that valve gap, pressure regulating valve, valve seat surrounded, after the through hole on the valve seat sidewall, adjustable ring flow to brake cylinder; When braking force increases, the corresponding increase of pressure of braking fluid, entering braking fluid in the valve gap passage this moment promotes pressure regulating valve and moves and make the 3rd length of spring compressed, realization by low pressure to high-voltage conversion, this moment pressure regulating valve and the interchannel gap increase of valve gap, the brake noise liquid phase that flows to brake cylinder should increase; When braking force further increased, the pressure of braking fluid made boiler check valve move compression second spring, oil duct is communicated with the sidewall through hole of pressure regulating valve and flows to brake cylinder, the process of finishing the work with through hole, the adjustable ring of described valve seat sidewall.After braking force is removed, first spring, second spring, the 3rd spring resets in succession, and the motor vehicle braking system internal pressure is got back to normal condition again.
The present invention to the control of braking recirculating oil quantity, brake-pressure difference, remains on the decelerated movement in the controlled range during by car brakeing when making car brakeing, be embodied in:
One, stopping distance obviously shortens: shorten response time thereby the present invention has the effect and the function of waiing upon clothes pressure in the adjusting brake system, reach the purpose that shortens stopping distance, stopping distance can shorten more than 10%.
Two, has good anti-locking brake function.The adjusting of this device by the pressure change procedure makes and keeps direction to have controlled preferably in the braking procedure.
Three, prevent from effectively to break away and whipping, the stability of braking improves.The present invention is at glancing impact, braking liquid is under the effect of braking force, and brake-pressure is not directly to enter brake cylinder, but by after the structural change of device, the pressure and the time that make braking liquid arrive wheel cylinder change, thereby prevent the sideslip and the whipping of vehicle effectively.
Four, dependable performance: after the present invention was installed, glancing impact can realize that a pin puts in place, makes chaufeur can accurately judge stopping distance, reaches the accurate stopping purpose; The present invention can the braking liquid seepage not occur because of precharge pressure is arranged in the brake line, can glancing impact yet because of braking force increases rapidly, the tube wall increased pressure causes the pipe breakage leakage of oil, even failure of apparatus still can keep the original deceleration and stopping performance of vehicle constant.
