Abstract
The utility model discloses an electromagnetic device for automatically adjusting a brake clearance, and relates to the technical field of automatic control of brake systems. The electromagnetic device comprises brake sheets (1), steel backs (2), electromagnetic proximity switches (3), a singlechip (4) and a brake disk (5), wherein along with the abrasion of the brake sheets, the distances between the brake sheets and the brake disk are gradually changed; and in spite of overlarge and oversmall distances, the brake effect is influenced. The electromagnetic proximity switches (3) are non-contact detection devices and are arranged at two ends of each steel back (2); when the electromagnetic proximity switches (3) get close to the brake disk (5), the distances are different, and the signal strengths are different; signals with different strengths are transmitted to the singlechip (4); and therefore, the signal strength can reflect the distances between the brake sheets (1) and the brake disk (5). If the distances are improper or the brake sheets are severely abraded, the brake sheets are manually adjusted or replaced.
Description
Technical field:
The utility model relates to the brake block technical field, is specifically related to a kind of electromagnetic type braking gap automatic control tegulatingdevice.
Background technique:
At present, the brake of motor-driven vehicle sheet is as an important component part of motor vehicle brake device, and the quality of brake of motor-driven vehicle braking effect depends on the effect of brake block to a great extent.The ABS that automobile is equipped with, TCS etc. guarantee the control gear of braking in time, and purpose is to let advancing of the car people that can leave control reliably, even can control automatically; The accident of stopping produces personnel, property damage.Performances such as safe, energy-conservation, efficient, quick, comfortable are more paid attention in current new model exploitation, and a lot of car generally than in the past more greatly, heavier, faster, therefore also increasingly high to the requirement of brake member.
Brake block is mechanically stressed through at base plate in use, and on the brake disc of wheel, rubbing forms brake.Brake disc is exactly the plate of a circle, and it also rotated when car was advanced.Brake caliper be used for two clamp brake disc and produce braking force.Its counterrotating brake disc is fixed.Be exactly that it clamps the effect that brake disc plays deceleration or stops when touching on the brake.
The working principle of disk type braker is by hydraulic control, and main parts size has brake disc, wheel cylinder, brake calipers, oil pipe etc.The alloy steel for braking discs manufacturing also is fixed on the wheel, with wheel; Wheel cylinder is fixed on the base plate of break; Two friction plates on the brake calipers are contained in the both sides of brake disc respectively.During brake, the hydraulic pressure that the piston of wheel cylinder is transported by oil pipe promotes friction plate and presses to brake disc generation friction catch, and it just looks like to vise the plate in the rotation with pliers that action is got up, and it is the same to force it to stop.
Two friction plates on the brake calipers are contained in the both sides of brake disc respectively, and along with the wearing and tearing of brake block, the distance between brake block and the brake disc also changes gradually.If the distance between brake block and the brake disc is too small, in normal driving process, may cause brake block to receive unnecessary wearing and tearing, reduce the life-span; If the distance between brake block and the brake disc is excessive, during brake between brake block and the brake disc pressure not enough, cause braking effect not obvious.
Claiming static position switch again near switch, is a kind of detection device of non-contact type, near brake disc, and when being close to certain distance, will produce electrical signal near switch as switch, and distance is different, and signal intensity is also different.Characteristics have reliable operation, long, low in energy consumption, multiple Location accuracy of life-span is high, operating frequency is high and adapt to bad working environment etc.If electromagnetic type is used in brake control field near switch, the automatic control that can improve brake block guarantees traveling security.
The model utility content:
The purpose of the utility model provides a kind of electromagnetic type braking gap automatic control tegulatingdevice; Its advanced design; Reasonable idea, an electromagnetic type is respectively installed near switch in two ends on each brake block steel back, regulates the distance between brake block and the brake disc through electromagnetic type near switch.On the one hand, make to keep best spacing between the two, braking device reaches best braking effect; On the other hand, can survey the degree of wear of brake block, in time change brake block, guarantee traveling security.
In order to solve the existing problem of background technique, the utility model is to adopt following technological scheme: it comprises brake block 1, steel backing 2, electromagnetic type near switch 3, single-chip microcomputer 4, brake disc 5.Wherein electromagnetic type is installed in the two ends of steel backing 2 near switch 3.
Described electromagnetic type is TCA505 near switch 3 models, comprises parts such as coil, magnetic core, steel disc, because brake disc is a metallic material, this device can save steel disc.Electromagnetic type is installed in the two ends of steel backing 2 near switch 3, electromagnetic type near switch 3 along with steel backing moves forward and backward.
Described electromagnetic type is a Q type enameled cable near the coil copper cash of switch 3, and diameter is 0.3mm, and length is 1000 circles.
When switch near brake disc, and when being close to certain distance, will produce electrical signal near switch, distance is different, signal intensity is also different.The lead that is connected on the coil can be delivered to the intensity various signals on the single-chip microcomputer 4, according to signal intensity, goes out the distance between brake block 1 and the brake disc 5 through computed in software.If find the improper or brake block serious wear of distance, through manual work adjustment or replacing brake block, make braking device reach best braking effect, guarantee traveling security.
The utlity model has following beneficial effect: it is rational in infrastructure, and design concept is advanced, on the one hand, makes to keep best spacing between the two, and braking device reaches best braking effect; On the other hand, can survey the degree of wear of brake block, in time change brake block, guarantee traveling security.
Description of drawings:
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model steel backing side structure schematic representation.
Embodiment:
Referring to Fig. 1 and Fig. 2, this embodiment is to adopt following technological scheme: it comprises brake block 1, steel backing 2, electromagnetic type near switch 3, single-chip microcomputer 4, brake disc 5.Wherein electromagnetic type is installed in the two ends of steel backing 2 near switch 3.
Electromagnetic type is TCA505 near switch 3 models, comprises parts such as coil, magnetic core, steel disc, and the coil copper cash is a Q type enameled cable, and diameter is 0.3mm, and length is 1000 circles.
Because brake disc is a metallic material, this device can save steel disc.Electromagnetic type is installed in the two ends of steel backing 2 near switch 3, electromagnetic type near switch 3 along with steel backing moves.
Electromagnetic type near switch 3 and brake disc 5 near the time will produce electrical signal, distance is different, signal intensity is also different.The lead that is connected on the coil can be delivered to the intensity various signals on the single-chip microcomputer 4, according to signal intensity, goes out the distance between brake block 1 and the brake disc 5 through computed in software.If find the improper or brake block serious wear of distance, through manual work adjustment or replacing brake block.
Show that through the laboratory test checking this embodiment is simple in structure, design concept is advanced, makes full use of the characteristic of electromagnetic type near switch 3, has strengthened the automation control of brake system, has effectively reduced the potential safety hazard that automobile produces in motion.
