Abstract
The utility model relates to an adjusting and stabilizing device of a hydraulic braking system for an automobile, relating to the technical fields of hydraulic elements and brake systems for automobiles. A casing is formed by that an upper body and a lower body are combined; a solid energy storage block is arranged in the inner cavity of the lower body; the bottom of the solid energy storage block is provided with an adjusting gasket; pistons are arranged in the inner cavities of the upper body and the lower body; sealing rings are arranged on the pistons; the pistons and the bottom of the lower body are provided with positioning cavities; the upper part of the upper body is provided with a radiating fin and an air release valve. The device is conveniently arranged between a main braking cylinder and a braking oil pipe by a main cylinder joint, an oil pipe joint, a transition joint and a turning joint. The utility model has the advantages of reasonable structure, convenient installation, wide use range and high safety.
Description
The utility model is the adjusting stabilizing device of hydraulic brake system of motor vehicle, relates to Hydraulic Elements and motor vehicle braking systems field.
Present domestic popular hydraulic brake system of motor vehicle, great majority adopt the hollow rubber elements as energy-storage travelling wave tube, and with the air that produces back pressure outside interior brake circuit of its separate cavities and the chamber.Be the braking effect that reaches good during use, the pressure of air often greater than the braking oil pressure of normal glancing impact, consequently makes such device exist a kind of potential danger, in case promptly energy-storage travelling wave tube lost efficacy, high pressure air can overflow into pipeline, causes brake failure.The product that has has recently been done partly to improve to said apparatus, change energy-storage travelling wave tube into entity, but its sealing means is still unreasonable, with the flanged structure of energy-storage travelling wave tube itself, for reaching excellent sealing effect, when such dress system is installed, flange is by the adjacent elements compacting, consequently limited the distortion that energy-storage travelling wave tube should reach, thereby when using, a little less than the impact that produces during to brake, the vibrations reaction.
The purpose of this utility model is existing apparatus is done the improvement of essence, a kind of adjusting stabilizing device of hydraulic brake system of motor vehicle is provided, this device can be in narrow space, be installed in easily between the master cylinder and brake oil pipe of automobile, make self-propelled vehicle in the process of emergency brake, can prevent wheel lockup, sideslip, sideslip, shorten braking distance again.Make vehicle have controllability, can make oil circuit and energy-storage travelling wave tube isolated simultaneously, the safety and the service life of having improved this device greatly.
The utility model is realized by following technical scheme: this device is that four joints are installed in body between the master cylinder and brake oil pipe of automobile with sealing tight master cylinder joint, oil connector, center coupling and steering knuckle.The shell of this device is tightly connected by upper body and lower body two parts, a piston is installed in the intracoelomic cavity under the upper body, pair of seal rings is installed to finish the sealing of oil circuit and energy storage section on the piston, energy-storage travelling wave tube adopts entity energy storage piece, be installed in lower part center in the chamber, bearing cap shim is installed additional in bottom at the energy storage piece, adjustment by spacer thickness, can make the energy storage piece be in the different emergency state, make this device be adapted to different vehicles, around it, be provided with the part cavity, the bulge-structure that descends two ends to be provided with positioning chamber and energy storage piece two ends thereon matches, make energy-storage travelling wave tube under extreme dress attitude, still keep right alignment with last lower body and piston, thereby make the device can normal operation.Heat radiation and aie escape valve structure are arranged, to slow down the influence of automotive engine heat radiation to this device working stability on top, upper body.
Advantage of the present utility model is: rational in infrastructure, easy to process, on the basis that keeps prior art and every performance figure, enlarged range of use, and improved safe reliability, can be used for having the various automobiles of hydraulic brake system, on the truck.
Description of drawings: Fig. 1 is a structural representation of the present utility model
Below in conjunction with drawings and Examples the utility model is further elaborated; The utility model as shown in Figure 1, its structural housing comprises that upper body 1, lower body 2 adopted and is threaded that the junction scribbles the leakage that sealant further prevents braking liquid.Energy storage piece 3 is installed in the cylindrical cavity of lower body 2, in the bottom of energy storage piece 3 bearing cap shim 4 is installed, form cavity 5 by the inner chamber of lower body 2 and the outer wall of energy storage piece 3, the effect of this cavity 5 is, make the distortion of energy storage piece 3 leave the space, need not pressurize during installation, air can not leak during use, piston 6 is installed in upper body 1 and lower body 2 inner chambers, a pair of seal ring 7 is installed on the piston 6, be respectively equipped with positioning chamber 8 and positioning chamber 9 in the bottom of piston 6 and lower body 2, they match with the bulge-structure of energy storage piece 3 upper and lower sides.The radiating gill 10 and the aie escape valve 11 that are installed in 1 top, upper body have solved the influence of automotive engine heat radiation to this device working stability.The master cylinder joint 12, oil connector 13, center coupling 14 and the steering knuckle 15 that are provided with are placed in this device between master cylinder and the brake oil pipe easily.The design of each joint fully takes into account the sealing of system, during automobile brake, pressure oil in the brake system is by the endoporus of each joint, act directly on the piston 6, make it to make back and forth movement with the variation of oil pressure, compress or loosen the energy storage piece that is positioned under it 3 and store or release energy, alleviate impact, vibrations that braking moment oil circuit produces, thereby prevent locking, sideslip, sideslip and the shortening braking distance of wheel effectively.
