Description
Technical Field
The utility model relates to a checking cylinder field, especially a spring brake cylinder for parking checking cylinder.
Background
The traditional brake system mainly has the structural types of mechanical type, pneumatic type, hydraulic type and gas-liquid mixed type. The brake cylinders are basically the same in working principle, and the brake devices are used for gradually consuming kinetic energy of a vehicle by using frictional heat generated during working so as to achieve the purpose of braking and decelerating the vehicle or stopping the vehicle, so that the brake cylinders are particularly important, and the traditional brake cylinder is formed by welding a plurality of parts, so that the problems of long processing time, low efficiency, high risk and the like exist.
SUMMERY OF THE UTILITY MODEL
In order to solve the problems in the prior art, the utility model provides a spring brake cylinder for a parking brake cylinder, which adopts an integrally formed cylinder body, improves the processing efficiency and has better sealing performance; meanwhile, the stainless steel material is adopted, so that the strength is improved, and the durability is increased.
The utility model adopts the technical proposal that:
the utility model provides a spring brake cylinder for parking brake jar, includes base and integrative cylinder body that takes shape, be equipped with last air inlet and lower air inlet on the base, be equipped with two transversal first rubber seal who personally submits "Y" shape in the base, two be equipped with transversal second rubber seal who personally submits "O" shape between the first rubber seal, be equipped with the exhaust hole on the cylinder body lateral wall, the base connects soon through screw thread and cylinder body, the base with be equipped with transversal third rubber seal who personally submits "O" shape between the cylinder body.
Further, the base is made of aluminum alloy.
Further, the cylinder barrel body is made of stainless steel.
The utility model has the advantages that:
1. adopt integrated into one piece's cylinder body, need not welding process, cylinder body and base only need through the screw thread connect soon together can, reduced the process.
2. Be equipped with the sealing washer between cylinder body and the base, improved the leakproofness, and then improved efficiency.
3. The cylinder barrel body is made of stainless steel, so that the strength and the hardness are better, the durability is improved, and the cost is saved.
4. The base adopts the aluminum alloy material, has alleviateed whole weight, and is more convenient when the installation is used.

Detailed Description
Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
Examples
As shown in fig. 1-4, a spring brake cylinder for a parking brake cylinder includes a base 1 and a cylinder body 2 formed integrally, the base 1 is provided with an upper air inlet 6 and a lower air inlet 7, two first rubber seal rings 3 having a Y-shaped cross section are disposed in the base 1, a second rubber seal ring 4 having an O-shaped cross section is disposed between the two first rubber seal rings 3, a vent hole 8 is disposed on a sidewall of the cylinder body 2, the base 1 is screwed with the cylinder body 2 through a thread, and a third rubber seal ring 5 having an O-shaped cross section is disposed between the base 1 and the cylinder body 2.
The device acts on the outside of the spring brake cylinder as shown in figure 5, and the working principle is as follows: compressed air is input into the cylinder barrel body 2 through the upper air inlet 6, the cylinder barrel body 2 stores the compressed air, when the pressure value of the compressed air in the cylinder barrel body 2 reaches a certain value, the brake spring 10 is compressed, the spring brake screw 9 is pushed upwards through the spring brake piston, when the spring brake screw 9 needs to be moved back to the original position downwards, air is exhausted out of the cylinder barrel body 2 through the air outlet, and the spring brake screw 9 is moved back to the original position downwards through the screw reset spring 11; compressed air is supplied to the lower portion of the base 1 through the lower air inlet 7, thereby facilitating the operation of the components connected to the lower portion of the base 1. The cylinder barrel body 2 is of an integrally formed structure and is simple in structure, the outer part of the cylinder barrel body 2 is provided with threads, and the threads are screwed with the base 1, so that the machining procedures are reduced, and the working efficiency is improved; and the four corners junction of cylinder body 2 and base 1 is equipped with a plurality of third rubber seal 5, seals cylinder body 2 and base 1, has improved the leakproofness, has further guaranteed the energy storage effect. Base 1 is inside to be equipped with a plurality of first rubber seal 3 and second rubber seal 4, seals base 1 and spring brake screw 9, further improves working effect.
In one embodiment, the base 1 is made of aluminum alloy. The aluminum alloy material is adopted, the whole weight is reduced, and the installation and the use are more convenient.
In one embodiment, the cylinder body 2 is made of stainless steel. The stainless steel material is adopted, so that the strength and the hardness are better, the durability is improved, and the cost is saved.
The above-mentioned embodiments only express the specific embodiments of the present invention, and the description thereof is specific and detailed, but not construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention.
