Abstract
The utility model relates to a mechanically hydraulic anti-locking device for a brake. The device is an anti-locking device for an automobile hydraulic brake. The self safety of the device is enhanced by the design of a metallic piston of the mechanically hydraulic anti-locking device for a brake, and the reliability of the automobile brake is more enhanced. The device causes the direction of the automobile to be controlled in the process of the automobile braking. The braking distance can be shortened, and comfortable feeling is served to the passengers.
Description
The utility model relates to a kind of automobile hydraulic brake anti-embracing unit, and its design goal is in order to strengthen the durability of this device self, thereby has also strengthened the safety of braking automobile.
At present, the anti-embracing unit of mechanical type brake both at home and abroad is of a great variety, but energy-storage travelling wave tube mostly is aerated capsule, this device is owing to the stretching vibration of capsule adds and the brake solution direct contact, therefore quickened the aging of himself, both can break in case capsule is aged to the limit, at this moment be entered brake system, cause that brake system was malfunctioning by the high pressure gas of apart capsules cognition.It also is the defective that itself exists that the capsule-type anti-embracing unit braked soft.A kind of piston type anti-embracing unit is arranged cause really up to the mark the making of brake to prevent that armful effect is undesirable to the hydraulic pressure variation is insensitive because metallic piston and rubber elastomer diameter proportion are excessive.Also have a kind of device to increase more complicated accessory, so not only increased the cost but also easier the going wrong of product in order to prevent capsules break gas leakage.The brake anti-embracing unit that adjustable inside gives pressure is in order to adapt to different automobile types with different vehicle conditions and design-calculated, and external like product voltage regulation screw design in enclosure, owing to outside often adjusting and be exposed to, therefore exist the potential danger of pressure with Louing.
It is a kind of simple in structure, safe, practical and can strengthen the hydraulic vehicle braking anti-embracing unit of brake anti-embracing unit self durability that the purpose of this utility model is to provide.
The purpose of this utility model is achieved in that cored screw is connected on the shell, and pressure regulating valve, pressure-sensitive metallic piston, O-ring seal, rubber piston are installed in the enclosure in order, and by bottom shell are sealed, and bleed screw is installed in the upper end of shell.This device is installed in the hydraulic tubing of automobile brake general pump, and when the automobile emergency glancing impact, brake fluid enters shell inner cavity by connecting cored screw, and along with the continuous rising of oil pressure in the pipeline, metallic piston moves downward under the pressure of braking liquid.Rubber piston is compressed and adjusts at any time the pressure of braking liquid, makes the locking point of braking liquid internal pressure out of reach wheel have enough braking forces simultaneously again.The high pressure gas of annular space sealed and play the two-fold safety effect in the O-ring seal of metallic piston and rubber piston will install under the pressure of brake fluid.The diameter of metallic piston and rubber piston is identical in this device, and promptly having overcome the soft defective of braking has also increased the sensivity that hydraulic pressure is changed.The design of pressure regulating valve in this device is in enclosure interior, and below the bleed screw, this design has more increased safety control than external voltage regulation screw design at the like product of enclosure.Pressure regulating valve can be adjusted brake anti-embracing unit in-to-in and give pressure to adapt to dissimilar vehicles.Owing to take such scheme, automobile not only has the function of anti-lock but also has controllability in braking procedure.Because the tire rolling friction is the adhesive ability during greater than friction of rest to ground-surface adhesive ability, institute and brings comfort for driver and occupant when normal the deceleration so that braking distance shortens, and is bringing safety just protecting for when emergency braking driver and occupant.
Below in conjunction with accompanying drawing the utility model is further specified
Accompanying drawing is the sectional structural map of this device
1 connects cored screw, 2 shells, 3 pressure-sensitive metallic pistons, 4 O-ring seals, 5 rubber pistons, 6 bottoms, 7 aie escape valves, 8 pressure regulating valves among the figure.
Vehicle is when brake in the accompanying drawings, braking liquid is pressed in the shell (2) by connection cored screw (1) and acts on pressure-sensitive metallic piston (3), along with the increase metallic piston (3) of brake fluid pressure moves downward and compressing rubber piston (5), the power that wheel lockup point produces during brake is absorbed by rubber piston, pressure when releasing energy when rubber piston pops up in order to the maintenance hydraulic braking, the active distance during with the assurance car brakeing.In order to strengthen the sealing property of metallic piston, two seals cushion rubber (4) is arranged on metallic piston, during the downward compressing rubber piston of metallic piston, the rubber piston stress deformation forms the three seals circle simultaneously, rubber piston will be good more in the big more sealing property of the pressure that is subjected to, thereby it is excessive to eliminate a spot of pressure gas in rubber piston lower annular space, has stopped brake anti-embracing unit self and has damaged the malfunctioning accident of brake system that causes.Wheel can locking below 30 kilometers the time to guarantee the vehicle speed per hour for the pressure that pressure regulating valve can be adjusted rubber piston, and vehicle speed per hour wheel more than 30 kilometers the time is in the rolling braking state, at this moment bearing circle can controlling party to avoiding barrier.Aie escape valve (7) is used for bleeding off the air in the pipeline when anti-embracing unit is installed.Bottom (6) seals each parts in the enclosure, thereby has guaranteed safety and the reliability of this device in vehicle operating.
Claims (3)
1, a kind of mechanical type hydraulic brake anti-embracing unit, by connecting screw rod, shell, the pressure-sensitive metallic piston, O-ring seal, rubber piston, bottom, bleed screw, pressure regulating valve is formed, and install in the enclosure in order, it is characterized in that shell (2) is threaded with bottom (6), pressure-sensitive metallic piston (3) is housed shell lower end inner chamber and there is horizontal and vertical tapped bore rubber piston (5) shell upper end, cored screw (1) screw thread is installed in the horizontal thread hole, pressure regulating valve (8) is contained in lower end, longitudinal screw hole and withstands on the metallic piston (3), and aie escape valve (7) is installed in upper end, shell longitudinal screw hole.
2, mechanical type hydraulic as claimed in claim 1 brake anti-embracing unit is characterized in that metallic piston is to be made and twice or three seals cushion rubber arranged by alloy.
3, mechanical type hydraulic as claimed in claim 1 brake anti-embracing unit, it is characterized in that rubber piston is a butt cone shape, its bottom has the cylindrical piston of 1～2mm, its diameter is identical with metallic piston.
