Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of brake air chamber components, in particular to a rubber needle-shaped membrane. Background Art
[0002] The function of the brake air chamber (i.e., brake air chamber) is to convert the pressure of compressed air into mechanical force to rotate the brake camshaft to achieve braking action. The brake air chamber is a clamp-clamped diaphragm type. The front and rear brake air chambers are different in size, but their structure is basically the same; the brake air chamber is a device composed of an air inlet, a cover, a diaphragm, a support plate, a return spring, a housing, a push rod, a connecting fork, a clamp and bolts, etc., also known as a slave cylinder. When the car brakes, air enters the brake air chamber from the air inlet, and the diaphragm is deformed under the action of air pressure, pushing the push rod, and driving the brake adjustment arm, rotating the brake cam, pressing the brake shoe friction pad against the brake drum to produce braking.
[0003] The diaphragm in the existing brake air chamber is clamped between the upper and lower covers. When the diaphragm is deformed, the deformation at the connection between the fixed part of the diaphragm edge and the center deformation is the largest, which can easily cause damage and rupture at the connection, greatly reducing the service life. At the same time, the deformation and recovery of the existing diaphragm completely rely on its own elasticity, and the deformation recovery is not fast, resulting in a slow overall response, affecting the effect of continuous braking.
[0004] Therefore, it is necessary to invent a rubber needle-shaped membrane to solve the above problems. Utility Model Content

[0007] The membrane main body assembly includes a membrane peripheral edge arranged in a cylindrical shape, and the outer side wall of the membrane peripheral edge is arranged in an arc shape;
[0008] The membrane mounting edge assembly includes a mounting edge, and the bottom end of the membrane surrounding edge is located on the inner side of the bottom of the mounting edge.
[0009] Preferably, a membrane top is integrally formed at the top end of the membrane surrounding edge, and the edge of the membrane top and the top end of the membrane surrounding edge are connected in a rounded manner.
[0010] Preferably, the bottom end of the membrane surrounding edge is integrally formed with an arc-shaped connecting edge, and the arc-shaped connecting edge is arranged in an arc shape.
[0011] Preferably, the arc-shaped connecting edge is arranged close to the inner side of the membrane surrounding edge and tangent to the bottom end of the membrane surrounding edge, and the outer side of the arc-shaped connecting edge and the inner side of the installation edge are integrally formed.

[0014] Technical effects and advantages of the utility model:

The arc-shaped connecting edge is arranged in an arc shape and is located at the bottom of the installation edge. At the same time, the connection between the arc-shaped connecting edge and the membrane surrounding edge is tangent. Therefore, when the bottom of the membrane surrounding edge is deformed, it will be smoother and there will be no large pulling force on the connection between the arc-shaped connecting edge and the installation edge. Therefore, the connection between the arc-shaped connecting edge and the installation edge is not easy to break, thereby improving the service life. At the same time, due to the arc-shaped setting of the arc-shaped connecting edge and the setting of multiple elastic strips, the elastic strips have good elastic recovery ability, and can quickly restore the deformation of the membrane surrounding edge after the membrane surrounding edge is deformed, thereby improving the response speed and improving the effect of continuous braking.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0021] The utility model provides Figure 1-3 The rubber needle-shaped membrane shown in the figure includes a membrane main body assembly 1 and a membrane mounting edge assembly 2. The membrane main body assembly 1 is integrally formed with the membrane mounting edge assembly 2 around its edge. The membrane main body assembly 1 includes a cylindrical membrane peripheral edge 101, and the outer side wall of the membrane peripheral edge 101 is arranged in an arc shape. The top of the membrane peripheral edge 101 is integrally formed with a membrane top 102, and the edge of the membrane top 102 is connected to the top of the membrane peripheral edge 101 in a rounded corner. The bottom end of the membrane peripheral edge 101 is integrally formed with an arc-shaped connecting edge 103, and the arc-shaped connecting edge 103 is integrally formed with the bottom end of the membrane peripheral edge 101. The connecting edge 103 is arranged in an arc shape, and the membrane surrounding edge 101 and the installation edge 201 are connected by the arc connecting edge 103. The arc connecting edge 103 is arranged in an arc shape and is located at the bottom of the installation edge 201. At the same time, the connection between the arc connecting edge 103 and the membrane surrounding edge 101 is tangent, so when the bottom of the membrane surrounding edge 101 is deformed, it will be smoother, and there will be no large pulling force on the connection between the arc connecting edge 103 and the installation edge 201. Therefore, the connection between the arc connecting edge 103 and the installation edge 201 is not easy to break, thereby improving the service life;
[0022] The arc-shaped connecting edge 103 is arranged tangent to the bottom end of the membrane surrounding edge 101 near the inner side of the membrane surrounding edge 101, and the outer side of the arc-shaped connecting edge 103 is integrally formed with the inner side of the mounting edge 201. The outer side wall of the membrane surrounding edge 101 is fixedly provided with a plurality of elastic strips 104 distributed in a circular array, and one end of the 104 away from the membrane surrounding edge 101 is fixedly connected to the inner side wall of the mounting edge 201. The elastic strip 104 is a thin PVC strip with good resilience. The number of elastic strips 104 is generally set to 2-4. Too many elastic strips will affect the deformation of the membrane surrounding edge 101. The thickness of the elastic strip 104 is 1mm-2mm. Too thick will affect the deformation of the membrane surrounding edge 101, and too thin will easily break. Due to the arc setting of the arc connecting edge 103 and the setting of multiple elastic strips 104, the elastic strip 104 has a good elastic recovery ability, which can quickly restore the deformation of the membrane surrounding edge 101 after the membrane surrounding edge 101 is deformed, thereby improving the response speed and the effect of continuous braking.
[0023] Furthermore, the membrane mounting edge assembly 2 includes a mounting edge 201, and the bottom end of the membrane surrounding edge 101 is located on the inner side of the bottom of the mounting edge 201. The bottom end of the mounting edge 201 is integrally formed with a plurality of convex rings 202, and the plurality of convex rings 202 are distributed at equal intervals. By providing a plurality of convex rings 202, the friction force of the mounting edge 201 can be improved, and the stability of the membrane installation can be improved.
[0024] Working principle of this utility model:
[0025] When in use, the membrane surrounding edge 101 and the mounting edge 201 are connected by an arc-shaped connecting edge 103. The arc-shaped connecting edge 103 is arranged in an arc shape and is located at the bottom of the mounting edge 201. At the same time, the connection between the arc-shaped connecting edge 103 and the membrane surrounding edge 101 is tangent. Therefore, when the bottom of the membrane surrounding edge 101 is deformed, it will be smoother, and there will be no large pulling force on the connection between the arc-shaped connecting edge 103 and the mounting edge 201. Therefore, the connection between the arc-shaped connecting edge 103 and the mounting edge 201 is not easy to break, thereby improving the service life. At the same time, due to the arc-shaped setting of the arc-shaped connecting edge 103 and the setting of multiple elastic strips 104, the elastic strips 104 have excellent elastic recovery ability, which can quickly restore the deformation of the membrane surrounding edge 101 after the membrane surrounding edge 101 is deformed, thereby improving the response speed and the effect of continuous braking.
