Description
Technical field
The utility model relates to field of mechanical technique, specifically a kind of automobile braking apparatus in the traffic tool.
Background technique
Now, brake gear extensively is used on the Motor Vehicle with the friction type working principle usually, generally only has one type, and that is exactly frictin braek, its break braking principle all is to rely on braking plate to compress wheel hub wall or card phase mutual friction carry-over moment, reaches the braking purpose.There is the shortcoming of several aspects in friction stopping device: (1) braking plate poor radiation, and friction time is slightly long, easily produces high temperature; (2) water funk, the wet goods dirt; (3) quick abrasion, yielding.In view of the various shortcomings of above original break, the annual traffic accident that occurs because of braking effect reduction or braking failure is a lot, causes heavy economic losses and personal injury to society.
Summary of the invention
The purpose of this utility model is to overcome the deficiency that existing brake gear exists, and provides a kind of and original brake gear by the diverse braking method of wall friction carry-over moment.The utility model is to press Special-shaped sheet spring contact by the top bolt, makes the deflection of Special-shaped sheet spring, the reed on the press-bending Special-shaped sheet spring and produce the method that moment is transmitted.This brake gear can improve carry-over moment greatly, and can overcome again original device and produce high temperature because of friction, abrasion deformation, or the impact of water, greasy dirt reduces the carry-over moment effect even the shortcoming such as inefficacy.
Technological scheme
The concrete technological scheme of bolt spring press-type break is, in the fixing flute profile ring seat of wheel hub inwall, a top bolt guide bracket that is solidly set on the wheel axle put in the inner chamber of flute profile ring seat; Utilize Special-shaped sheet spring on the wheel hub inwall flute profile ring seat and the top bolt in the bolt guide bracket of top mutually to press with disengaging and reach braking driving function.The Special-shaped sheet spring is the rotating shaft that there is the cylindrical shaft shoulder at two ends, and there is the contact of curved projection in the rotating shaft stage casing to next side, and oriented both sides, the horizontal both sides of rotating shaft symmetry is stretched out gradually flat wide shape reed, reed end has the segment arc that makes progress to turn back; Be useful on the shoulder cover of rotational support on the shaft shoulder of Special-shaped sheet spring; A plurality of Special-shaped sheet springs by the shoulder cover on the shaft shoulder that is enclosed within the rotating shaft two ends, be installed on the round bar ring groove of flute profile ring seat inwall, the flute profile ring seat is cylindrical body, and round bar ring is arranged on its inwall, on the circle bar ring equally distributed cross groove is arranged; The flute profile ring seat is bolted on again on the wheel hub inwall or is fixed on the facing the wall and meditating of disk, one side the wheel hub opening has a tepetate, prevents that lubricant oil from overflowing, and dust enters; According to stressed design needs, go back the shape and structure of capable of regulating flute profile ring seat design proposal and Special-shaped sheet spring, the flute profile ring seat can have a plurality of round bar rings, or is set as flute profile dish seat.The rotating shaft of Special-shaped sheet spring also can be that a plurality of shaft shoulders for fixing are arranged, the shaft shoulder is provided with the shoulder cover, what of Special-shaped sheet spring can determine number according to the size of the size of flute profile ring seat or disk, the elastic force of Special-shaped sheet spring upper reed plate and number also can change to adjust according to the design carry-over moment, the relative angle of Special-shaped sheet spring upper reed plate and contact and relative position are looked the specific design project setting, because it is longer that the reed on the Special-shaped sheet spring stretches out both sides, and Special-shaped sheet spring distribute spacing is shorter, so, reed on the Special-shaped sheet spring can partially in two, the left and right sides or intermediate distribution, make things convenient for slot milling in rotating shaft, put down the Special-shaped sheet spring.When the contact of Special-shaped sheet spring is subjected to displacement, is subject to top bolt along anti-two directions and presses owing to wheel hub rotates, the Special-shaped sheet spring is offset according to the rotation of the rotating shaft heart, Special-shaped sheet spring upper reed plate will press flute profile ring seat inwall and flexural loading, Special-shaped sheet spring upper reed plate tortuosity is respective change also, because the buffering of lubrication and reed, wearing and tearing and impact force can reduce greatly between contact.When Special-shaped sheet spring contact slipped over top bolt head because deflection is excessive, the Special-shaped sheet spring set back by the reed rebounding force, and other top bolt is because the Special-shaped sheet spring moves, presses Special-shaped sheet spring contact, and this process that circulates reaches braking driving function.
The top bolt is the packet of wide bar shaped, near the dual-side that raises ring top bolt a fixedly flange of return spring is arranged respectively, and the top bolt has runner with the contact jaw that raises ring.The top bolt is loaded in the bolt guide bracket of top, top bolt guide bracket is a round-meshed cylinder in centre, by circle hole sleeve on wheel axle, top bolt guide bracket has one to put the annular chamber that raises ring near inner circle, be with a plurality of even distributions near excircle and be used for the fixedly chamber of top bolt, by ring-like chamber open side a side lid is arranged.Top bolt guide bracket is solidly set on the wheel axle, when top bolt head is subjected to Special-shaped sheet spring contact probe to cut down output living athwartship moment, top bolt guide bracket stops Special-shaped sheet spring contact traversing according to being fixed in wheel axle, when resistance is enough large, wheel hub stops operating, as long as there is rotation trend in wheel, also there is static pressure between the contact that is in contact with one another.Raising of top bolt is to be finished by a ring that raises that is enclosed within the bolt guide bracket of top.Raising ring is a straight-through tubular ring, raises regular distribution wedge shape reed on the ring outer wall, in order to reserve sufficient space, but wedge shape reed cross-distribution.Raise ring and promote according to the axle center rotation by drive link, finish raising function by wedge shape reed extruding top bolt.The top bolt with raise articulating contravention both sides flange and be installed with return spring, raise ring and can realize transmission agency by the suitable kind of drive.For preventing that the lubricant oil in the brake hub case from overflowing, the brake hub case seals relatively.
The bolt spring press-type break that the utility model proposes can be avoided because high-strength frictional heating produces high temperature, and stressed evenly have rational in infrastructurely, and braking is sensitive reliable, make simple, the characteristics such as long service life.Can be widely used in the break configuration of weight truck and dolly etc., be particularly useful for heavy truck break configuration, be the creativity and innovation to existing brake gear technical field fully.
