Description

A kind of steel welding formula double-diaphragm spring arrester

Technical field

The utility model relates to field, automobile brake chamber, especially a kind of steel welding formula double-diaphragm spring arrester.

Background technique

Traditional arrester, a general epithelium and the structure of piston of adopting, piston requires very high to working environment, generally all need to adopt muffler that the gas of back cavity is drained in the ante-chamber, if directly drain into atmosphere, have that some dusts and dirt suck in and life-span of influencing piston, so the cost of piston and accessory is higher; Middle body generally adopts this specialty of aluminium matter, and fabricating cost is also very high.

The model utility content

The utility model will solve the shortcoming of above-mentioned prior art, and a kind of steel welding formula double-diaphragm spring arrester is provided.

The utility model solves the technological scheme that its technical problem adopts: this steel welding formula double-diaphragm spring arrester, mainly comprise middle body, protecgulum, bonnet, first epithelium, second epithelium, tappet assembly, push-rod assembly, release dish and brute spring, described protecgulum and middle body are separated into driving chamber and ante-chamber by first epithelium, and bonnet and middle body are separated into back cavity and Parking chamber by second epithelium; Be provided with the push-rod assembly and first return spring in the ante-chamber, an end of push-rod assembly is connected with link, and the other end and first epithelium, one end face connect; Be provided with the tappet assembly and second return spring in the Parking chamber, one end of tappet assembly and the first epithelium other end connect, one end face of the other end of tappet assembly and second epithelium connects, be provided with release dish and brute spring in the back cavity, one end of brute spring is pressed on the other end of second epithelium by the release dish, the other end of brute spring is pressed on the bonnet inwall, and pore is connected with Parking chamber and driving chamber respectively.

As preferably, described in body be arranged between second epithelium and first epithelium, middle body is made by the steel plate welding.

The effect that the utility model is useful is: 1, adopt the structure of two epitheliums, cost is low, good reliability; 2, replace body in the aluminium matter with body in the steel welding formula, to make cost low for system in the steel welding formula, and near body 1/2nd in the aluminium matter, product intensity height is 1.5 times of alumiaum article, because steel plate all is the large quantities of a large amount of productions of big section steel works, quality control is tight, stable performance.Because steel are than aluminium intensity height, the product design is compacter, and outward appearance need not stiffening rib, and structure is brevity and lucidity more.

Description of drawings

Fig. 1 is the utility model master TV structure schematic representation;

Description of reference numerals: protecgulum 1, the first return spring 2, push-rod assembly 3, middle body 4, tappet assembly 5, the second return springs 6, brute spring 7, bonnet 8, Parking chamber 9, the second epitheliums, 10, the first epitheliums 11, driving chamber 12, release dish 13, link 14, pore 15, ante-chamber 16, back cavity 17.

Embodiment

The utility model is described in further detail below in conjunction with drawings and Examples:

As shown in Figure 1, this steel welding formula double-diaphragm spring arrester, body 4, protecgulum 1, bonnet 8, first epithelium 11, second epithelium 10, tappet assembly 5, push-rod assembly 3, release dish 13 and brute spring 7 in mainly comprising, body 4 is arranged between second epithelium 10 and first epithelium 11 in described, and middle body 4 is made by the steel plate welding.Described protecgulum 1 and middle body 4 are separated into driving chamber 12 and ante-chamber 16 by first epithelium 11, and bonnet 8 and middle body 4 are separated into back cavity 17 and Parking chamber 9 by second epithelium 10; Be provided with the push-rod assembly 3 and first return spring 2 in the ante-chamber 16, an end of push-rod assembly 3 is connected with link 14, and the other end and first epithelium, 11 1 end faces connect; Be provided with the tappet assembly 5 and second return spring 6 in the Parking chamber 9, one end of tappet assembly 5 and first epithelium, 11 other ends connect, one end face of the other end of tappet assembly 5 and second epithelium 10 connects, be provided with release dish 13 and brute spring 7 in the back cavity 17, one end of brute spring 7 is pressed on the other end of second epithelium 10 by release dish 13, the other end of brute spring 7 is pressed on bonnet 8 inwalls, and pore 15 is connected with Parking chamber 9 and driving chamber 12 respectively.

Working principle:

1, (during parking) during the working state parking braking, the gas in Parking chamber 9 and driving chamber 12 is discharged by pore 15, Parking chamber 9 and driving chamber 12 pressurized air are all removed, brute spring 7 is released, under the effect of brute spring 7, promote release dish 13, second epithelium 10 and tappet assembly 5 to left movement, the link 14 that tappet assembly 5 promotes push-rod assembly 3 and is connected with break, make brake calipers clamp brake disc, realize parking braking.

2, in the running process, gas enters Parking chamber 9 by pore 15, under the effect of pressurized gas, promoting second epithelium 10 moves right, thereby promote release dish 13, compression brute spring 7, second return spring, 6 promotion tappet assemblies 5 move right simultaneously, and push-rod assembly 3 moves right under 2 effects of first return spring; When needing braking, feed pressurized air by driving chamber 12 intake interfaces, by first epithelium 11 push-rod assembly 3 is released, make be fixedly clamped brake disc on wheel hub of brake calipers by the ball bowl, realization is removed the braking driving chamber 12 intake interface air pressure of automobile, push-rod assembly 3 is return under 2 effects of first return spring, and brake calipers opens, and braking is removed.

In addition to the implementation, all employings are equal to the technological scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
