Description
[technical field]
The utility model relates to a kind of automobile brake manual tune arm dust cover.
[background technique]
As everyone knows, automobile must possess braking system, guarantees safe enforcement.At present, brake system of car divides drum brake system and disk braking system.Automobile use and braking process in friction plate and the gap between the brake drum of each wheel must keep in balance, guaranteeing that automobile brake steadily, can not break away and whipping, regulating arm is exactly transmission power and adjust an assembly of braking gap in drum brake system.
Regulating arm on the market has many kinds of structural types now, automatic adjustable and Manual adjustable are arranged, a kind of lock tube locked type regulating arm that stretches is arranged in the manual tune arm, it is simple in structure, locking is stable and cost is low, therefore, it is most popular at present in drum brake system, most widely used a kind of manual arm, but this manual arm exposes because of lock tube and worm screw spindle nose, therefore, also cause it to have a fatal shortcoming to be, the sludge water that splashes in the vehicle traveling process and dust, the gap between lock tube and lock tube hole and worm screw spindle nose very easily enters into the inside extendable room of lock tube and deposits, when deposit dirt reach a certain amount of after, just not flexible of lock tube causes worm shaft not regulate regulating arm, and namely the regulatory function of regulating arm lost efficacy.Given this, each producer all adds a rubber sleeve at lock tube and prevents dust at present, and rubber sleeve is fixed on the screw thread pin place of lubricating cup.But this rubber sleeve has a defective, crosses pine and easily causes coming off, and tension then can't cover the lock tube root again, causes anti-fouling effect bad.The rubber material price skyrockets in recent years simultaneously, also causes the cost of rubber sleeve more and more higher.In order to overcome above-mentioned defective, we have developed a kind of automobile brake manual tune arm dust cover of the present utility model.
[model utility content]
The purpose of this utility model will provide a kind of automobile brake manual tune arm dust cover exactly, it can prevent the inside that the sludge water that splashes in the vehicle traveling process and dust enter into lock tube effectively, the turbidity test that keep regulating arm inside, solve simultaneously the problem that rubber sleeve is installed inconvenience, easily got loose, and have characteristics simple in structure, with low cost, easy to install.
The technological scheme that the utility model adopts is: a kind of automobile brake manual tune arm dust cover, it comprises lock tube cover section and oily cup unit, lock tube cover section be connected cup unit and connect by strip tape, be provided with fixed hole in the middle of the strip tape, dust cover can be fixed in larynx footpath section under the bulb of lubricating cup top by fixed hole, it is all very convenient to install like this and keep in repair.
Described dust cover lock tube cover section is provided with inner chamber, the bottom surface sealing of this inner chamber, and the inwall of inner chamber is provided with many little, the axial inclinations of thickness and embraces clip tooth.Embrace that circular diameter is less than lock tube external diameter 1～2mm in the clip tooth crown place.Embrace radially radius α at a certain angle of clip tooth and inner chamber, the α angle is 30 °～60 °, usually adopts 45 °, and this angle is to allow an armful clip tooth have sufficient elasticity, has again the enough folder power of embracing simultaneously.The end face of embracing clip tooth is provided with angle of deflection β, and the β angle is 15 °～45 °, usually adopts 30 °, easily covers on earth when this angle of deflection can make dust cover install, and guarantees that lock tube is dustproof, anti-fouling effect.
Described dust cover oil cup unit is hollow structure, and bottom lock, oral area are provided with the lubricating cup bayonet socket, the lubricating cup bayonet socket is the protruding circular ring shape, the minimum diameter place of lubricating cup bayonet socket is slightly less than the diameter of lubricating cup bulb, and the lubricating cup cover can be fixed on the lubricating cup, guarantees that lubricating cup is dustproof, anti-fouling effect.
Larynx footpath on the diameter of described dust cover fixed hole and the regulating arm under the lubricating cup bulb is identical, and fixed hole relies on the elasticity of material, enters larynx footpath section from the direct gland in lubricating cup bulb top, and keeps rotation activity cooperation, makes the dust cover can be around larynx footpath section center rotating.
Described dust cover material adopts soft plastic to make, and materials such as available polyethylene from high pressure process, flexible PVC is made.Because plastics molding process is simple, shaping efficiency is high, and material very easily obtains, and price is low again simultaneously, and this is just so that this dust cover product price is cheap.
Further, dust cover adopts polyethylene from high pressure process or pvc material to be made.
Further, the minimum diameter place of lubricating cup bayonet socket is less than the diameter 0.5～1mm of lubricating cup bulb place.
The utility model is compared with background technique and is had the following advantages:
The utility model has adopted above-mentioned technological scheme, compare with the vehicle manual regulating arm dust-proof cover of background technique, have simple in structure, cheap, installation, extremely easy to use, although use the plastic materials poor than rubber elasticity, but by the design of elastic structure cleverly, so that its armful folder stability, property easy for installation and dust-proof effect all reach and have surpassed original bellows.Because its very light in weight is embraced folder power much larger than its weight, therefore in the automobile running using process, can not cause that inertia comes off because jolting and shaking.Effectively stop extraneous dust and other impurities to enter into regulating arm inside, so that regulating arm inside is difficult for corrosion, avoid occurring stuck phenomenon, improve Safety performance.
