Abstract
The utility model relates to a hydraulic piston type anti-locking device for a wheel, which comprises a main body which is communicated with a braking base pump and a braking branch pump, wherein, the inner cavity of the main body is provided with an anti-locking mechanism for a wheel, and the anti-locking mechanism for a wheel is composed of a blockage, a spring seat, an oil inlet valve seat, an oil outlet valve seat, a diaphragm plate, a sealing seat, an idle spring, and a piston. The mechanism carries out oil pressure adjustment by a pressure adjusting spring and a pressure adjusting screw. The piston is prompted to jump and the wheel is caused to stay in the half rotation state on the occasion of braking by the change of the size of forward and backward pushing force to the piston, and the change of the size of forward and backward pushing force to the piston is caused by the force of the idle spring, the oil input pressure, and the returning force of the oil pressure of the branch pump. Therefore, the vehicle tail running phenomenon, the sliding phenomenon, and the eccentric phenomenon which are caused by completely locking are avoided. The device is free from the influence of the oil pressure size and the corrosion problem to the structure. Therefore, the hydraulic piston type anti-locking device for a wheel is successfully adjusted for once, the operation is convenient, the anti-locking effect is stable, and the service life is long.
Description
The utility model relates to automotive wheel brake anti-embracing unit.
Automobile is in the way of travelling, often run into and stop or unexpected brake, should the locking wheel during brake but locking fully, otherwise easily cause and skid, run the tail phenomenon, make automobile steering off normal, braking distance long, easily cause beyond thought accident to take place, for this reason, must between automobile brake general pump and wheel cylinder, wheel anti-lock device be set.The anti-embracing unit of sale use is gone up except that the electronic type that external import is introduced by society now, domestic self-produced have capsule-type and hydraulic pressure steel ball play formula, the former adopts the expansion of rubber capsule to shrink the effect of agitating, but because of the brake solution corrosive property stronger, make rubber deformation easily, shortened service life greatly, also can cause anti-armful of brake malfunctioning simultaneously; The latter is because of the oil pressure direction is positive and negative two sides operations, adds to have stepped on weight because of the chaufeur pin oil pressure is varied in size, and these all easily cause the steel ball inclination, make the anti-effect instability of embracing, and need often to regulate, and make troubles to the user.
The purpose of this utility model is to overcome the defective of prior art and provides a kind of oil pressure size that neither is subjected to influence, need not frequent adjusting, make and prevent embracing effect stability, there be not the corrosion of brake solution again, thereby improve the hydraulic piston type wheel anti-lock device in service life inner structure.
By the foregoing invention purpose, embodiment of the present utility model is: comprise main body, connect three of the wheel cylinder swivel nut that stimulates the menstrual flow and be sealedly connected on main body one end, the swivel nut oilhole and the threeway that connect the main body oilhole connect, the other end that is fixed on the main body on the adapter plate by tight cap links to each other with master cylinder, the main body inner chamber that connects with the swivel nut oilhole is provided with by pressure regulating screw, pressure spring is formed the anti-mechanism of embracing of hydraulic pressure play formula that oil pressure is regulated, it is characterized in that the described anti-mechanism of embracing comprises by stopping up spacing spring perch, and be provided with packing element leak free oil-feed valve seat between the main body, delivery valve seat, partition, seal receptacle, the oil-feed valve seat, delivery valve seat has and master cylinder, the oilhole that the wheel cylinder oil circuit connects, be provided with by seal ring and K RunddichtringO leak free piston in the seat, the idle spring pushing tow that is positioned at spring perch is in piston tail.
The utility model adopts one piece piston play principle, add that with idle spring elastic force thereby input pressure impels piston play to affact with wheel cylinder oil pressure return force to the size variation of the anti-jacking force of piston to the jacking force of piston and makes it be in the half way around state on the wheel, avoid complete locking, reach the anti-purpose of embracing, thereby make automobile avoid running tail when brake, skid, be partial to phenomenon, braking distance shortens greatly.Because this device is not influenced by the oil pressure size, so need not frequent adjusting, disposable regulating is easy to use during installation, the anti-effect stability of embracing of brake; There is not the etching problem of brake solution yet, thereby improved service life inner structure.
Accompanying drawing 1 has provided overall structure scheme drawing of the present utility model.
Embodiment to the utility model is further described again below with reference to above-mentioned accompanying drawing.
Hydraulic piston type wheel anti-lock device (referring to Fig. 1) is installed on the oil circuit between automobile brake general pump and the wheel cylinder, and its main body (1) is the four-way structure, is fixed on the adapter plate (not shown) by tight cap (9).Main body one end is connected with by swivel nut (5) fixing threeway (3) with being spirally connected of main body, faying face between the three is provided with the seal ring (4) of rubber system, the swivel nut oilhole (24) that connects the main body oilhole connects with threeway, the aie escape valve (not shown) is installed in one of threeway, two connect the braking automobile wheel cylinder respectively in addition, can pass through oil connector (2) and connect, perhaps wherein a nose end is bolted with the standby rubber system sealing plug (6) that plays dustproof effect.The oil inlet place that main body connects master cylinder is bolted with sealing plug equally.
Be provided with in main body (1) the inner chamber axis hole by pressure regulating screw (12), pressure spring (7) and form the anti-mechanism of embracing of hydraulic pressure play formula that oil pressure is regulated, this mechanism comprises by stopping up (23) spacing spring perch (22), and be provided with packing element leak free oil-feed valve seat (19), delivery valve seat (18), partition (17), seal receptacle (15) between the main body, wherein oil-feed valve seat, delivery valve seat and partition can be made into integral type, oilhole on oil-feed valve seat and the delivery valve seat and main body oilhole connect, and promptly connect with master cylinder, wheel cylinder oil circuit.Be provided with by the seal ring (20) of polytetrafluoroethylene system and K RunddichtringO (16) the leak free piston (14) of rubber system in the seat; pagoda shape idle spring (21) pushing tow that is positioned at spring perch is in piston tail; the pressure spring seat of regulating oil pressure is between upper spring seat (8) and the spring abutment of being hit by a bullet (13); position during the piston closes state and be hit by a bullet and leave enough gaps between the spring abutment; to guarantee the reliability of piston closes; the elastic force of pressure spring adds that by the jacking force of idle spring input pressure realizes regulating by pressure regulating screw, and fastening by nut (11).Be provided with the dust cap (10) that is spirally connected simultaneously in its end.
Automobile is when cruising, and piston is unlocked, and the master cylinder oil circuit communicates with the wheel cylinder oil circuit through the oilhole of oil-feed valve seat, delivery valve seat, main body, swivel nut, threeway.When need brake, the sealing surface of sealing and oil-feed valve seat under the pin pedal that touches on the brake, piston promote in idle spring power with from the master cylinder input pressure, then wheel cylinder oil return force is pushed piston again open, and play makes wheel not by locking so repeatedly, has promptly realized the anti-purpose of embracing.
