Abstract
The invention discloses an air disc brake. The air disc brake comprises a brake chamber 1 and a forceps assembly 2, wherein the brake chamber 1 comprises a shell 11, an elastic membrane 12, an air chamber 13 and a ball head ejector rob 14; the forceps assembly 2 comprises a seat body 21, a pressure arm 22, a screw rod 23, a connecting part 24, a double-piston assembly 25, a friction plate 26 and a brake disc 27; a sealing element 3 which can prevent the gas and moisture in the brake chamber from entering into the inner chamber of the forceps assembly is arranged at a position from which the ball head ejector rob 14 of the brake chamber 1 enters the inner chamber of the forceps assembly 2. The invention has the advantages that since the sealing element is arranged at the position from which the ball head ejector rob of the brake chamber enters the inner chamber of the forceps assembly, the gas and moisture in the brake chamber can be prevented from entering into the inner chamber of the forceps assembly, the components in the forceps assembly can be protected from rusting corrosion, and the safety and reliability of brake performance can be further ensured and improved.
Description
Technical field:
The present invention relates to a kind of automotive brake, specifically is a kind of air-pressure disc brake.
Background technique:
Along with the continuous expansion of freeway network, the raising of automobile speed and the increase of vehicle density, the functional reliability of brake system of car requires to seem and becomes more and more important.No matter air-pressure disc brake still is aspect the reliability at braking ability, and solves aspects such as brake noise, dust pollution, maintenance and all show great advantage.Along with the development of Domestic Automotive Industry technology, entering of advanced foreign technology adopted the air-pressure disc brake configuration progressively to form scale in China, and will be become the standard configuration of China's part automobile on the automobile.Air-pressure disc brake mainly is made up of brake chamber and caliper assembly, and brake chamber comprises housing, elasticity epithelium, air chamber, bulb push rod, and the caliper assembly comprises pedestal, pressure arm, screw rod, coupling and dual-piston assembly, friction plate and brake disc.During braking, pneumatic pump provides presses air to enter brake chamber, elasticity epithelium in the air chamber passes to the bulb push rod with air pressure, the bulb push rod presses down the pressure arm that promotes in the caliper assembly and rotates, when rotating output braking displacement, pressure arm realizes then the braking force behind braking displacement and the reinforcement being passed to reference seat by the braking force reinforcement.Pass to screw rod by reference seat, friction plate in screw rod promotes by push pedal, the gap in eliminating between friction plate and the brake disc, owing to the effect of reaction force, braking clamp body moves inwards simultaneously, drives outside friction disc and also fits with brake disc, thereby interior outside friction disc is embraced brake disc, realizes braking.The brake chamber of existing air-pressure disc brake and caliper assembly connecting part, that is to say that the bulb push rod enters caliper assembly inner chamber position and leaves the gap, during return after the expansion of the elasticity epithelium of the brake chamber compression, form negative pressure in the brake chamber easily, at this moment after air enters brake chamber from the air outlet of brake chamber, airborne moisture content enters caliper assembly inner chamber from this gap, thereby cause the component corrosion in the caliper assembly, and then make its component lose the uncertainty that adjustment causes the component action, bring unsafe hidden danger.
Summary of the invention:
The technical problem to be solved in the present invention is that defective and deficiency at above-mentioned prior art exists provide a kind of Safety performance height, the air-pressure disc brake of good reliability.
Technical solution of the present invention is:
A kind of air-pressure disc brake, comprise brake chamber and caliper assembly, described brake chamber comprises housing, elasticity epithelium, air chamber, bulb push rod, described caliper assembly comprises pedestal, pressure arm, screw rod, coupling and dual-piston assembly, friction plate and brake disc, its technical characterstic is, enters caliper assembly inner chamber place at the bulb push rod of brake chamber and is provided with the Sealing that the gas that prevents in the brake chamber and moisture content enter caliper assembly inner chamber.
Described Sealing is elastic seal cartridge or elastic seal ring.
After adopting above structure, compared with prior art, the present invention has the following advantages: enter caliper assembly inner chamber place at the bulb push rod of brake chamber and be provided with Sealing, gas and the moisture content that can block in the brake chamber enter caliper assembly inner chamber, prevent the component corrosion in the caliper assembly, advance Security and reliability that face further ensured and improved braking ability.
