Description

Single cylinder double action caliper

This creation is related to calipers, especially for a single-cylinder double-acting caliper.

Brake calipers are commonly used in vehicles that use the disc system as a brake, such as cars, locomotives, and bicycles. Conventional brake calipers have a caliper body, two blades, and two pistons. When the driver steps on the brake pedal or presses When the handlebar is braked, the piston in the brake caliper is driven by hydraulic pressure to push the disc to clamp a disc, and the friction disc is used to stop the rotation of the brake disc, thereby stopping the rotation of the tire.

There are two types of conventional brake calipers, one of which is a caliper body system integrally formed, and a cylinder chamber is disposed on opposite sides of the caliper body, and the second cover member is disposed on the outer side opening of the two cylinder chamber. To form a cylinder structure for accommodating a piston, such as disclosed in TWM318572; another type is that the caliper body is locked by two caliper portions, and each caliper portion is integrally formed with a piston for receiving A cylinder structure such as that disclosed in TWM343636 is such a structure.

However, in the above two conventional types of brake caliper structures, two sets of cylinders and pistons are required, which are complicated in structure, heavy in weight, difficult to prepare and assemble, and high in manufacturing cost, which is not conducive to rapid mass production. And the non-performing rate is high, which seriously affects product quality and competitiveness.

Therefore, it is necessary to provide a novel and progressive single-cylinder double-acting caliper. To solve the above problems.

The main purpose of the present invention is to provide a single-cylinder double-acting caliper which is simple in structure, light in weight, easy to prepare and assemble, and is advantageous for rapid mass production, low defect rate, and low manufacturing cost.

In order to achieve the above object, the present invention provides a single-cylinder double-acting caliper comprising a caliper body, a fixing member, a piston and a brake assembly. The caliper body has two first side portions and a second side portion opposite to each other, a receiving space formed by the first and second side portions, and a first side portion and a first side portion The housing space is open on one side of the cylinder chamber, and the cylinder chamber is connected to an external power source. The fixing member includes a fixed end located outside the caliper body and extends with at least one moving track, and the caliper body is slidably coupled to the moving track. The piston is movably disposed in the cylinder chamber and is drivable by the external power source. Each of the brake assemblies includes a backing plate and a routing piece disposed on the backing plate. The two backing plates are movably disposed between the first and second side portions of the caliper body by a pin member. The backing plate is actuatable by the piston toward an object relative to the piston.

The following is a description of possible implementations of the present invention by way of example only, and is not intended to limit the scope of the creation of the present invention.

Referring to FIGS. 1 through 5, a preferred embodiment of the present invention is shown. The single-cylinder double-acting caliper 1 of the present invention includes a caliper body 10, a fixing member 20, a piston 30, and two brake assemblies 40, 50.

The caliper body 10 has two first side portions 11 and a second side portion 12 opposite to each other, and a receiving space 13 formed by the first side portion 11 and the second side portion 12, and a plenum A cylinder chamber 14 is provided on the first side portion 11 and opens to one side of the receiving space 13, and the cylinder chamber 14 is connected to an external power source (for example, a brake oil pump assembly). The space 13 is open to the upper and lower sides, and is provided for the piston 30 and the two brake assemblies 40, 50. The caliper body 10 extends laterally with two spaced-apart arms 15 .

The fixing member 20 includes a fixed end 21 outside the caliper body 10 and extends with at least one moving rail 22 for securing a fixed base (such as a bicycle, a locomotive or other device suitable for a caliper). Pick up. In this embodiment, the fixing member 20 is integrally formed and includes a body 23 and is provided with two connecting ears 24, but may be designed according to different installation requirements. The at least one moving rail 22 includes two first rods 25 that are disposed in parallel with the body 23. In detail, the two first rods 25 are assembled to the two connecting ears 24, and the caliper body 10 is slidable. The first pole body 25 is detachably assembled to the body 10, and may be integrally formed with the body 23. The second arm 15 respectively corresponds to a portion of the fixing member 20, so that a limiting function can be provided, so that the caliper body 10 is provided. It can move relatively stably along the two first rods 25.

The piston 30 is movably disposed in the cylinder chamber 14 and is drivable by the external power source. Specifically, the piston 30 is a cylinder that is open in the same direction as the cylinder chamber 14. The cylinder has an actuating surface that is urged by the fluid in the cylinder chamber 14. The structural design can reduce the use of the oil body. The quantity can also achieve excellent hydraulic actuation.

The brake assembly 40 includes a backing plate 41 and a slab 42 disposed on the backing plate 41. The brake assembly 50 includes a backing plate 51 and a slab 52 disposed on the backing plate 51. 41, 51 is movably disposed between the first side portion 11 and the second side portion 12 of the caliper body 10 by a pin member 60, wherein the back plate 41 is opposed to the piston 30 by the piston 30 The object 70 is actuated. In detail, the sheet 42 is provided with two inserts 43, which are provided with two inserts 53, which are respectively inserted into the corresponding back plates 41, 51 and can be fixed or detachable. The group ground group is set on the corresponding backboard 41, 51. Preferably, an elastic member 80 is disposed between the two back plates 41, 51 of the brake assemblies 40, 50. One end of the elastic member 80 is disposed on the pin member 60 to provide the brake assembly 40. 50 return to power.

With further reference to FIGS. 6-7, in actual operation, when the piston 30 is actuated by the external power source, the piston 30 pushes against the brake assembly 40 to abut one side of the object 70, since the object 70 It is fixed to, for example, a bicycle, a locomotive or other device suitable for a caliper. After the brake assembly 40 is in contact with the object 70, a reaction force is applied to push back against the first side portion 11 to move the caliper body 10 backward. At the same time, the second side portion 12 is pushed against the brake assembly 50 to abut against the other side of the object 70, thereby achieving the single cylinder double motion brake action. When the pressure of the external power source is released, the elastic member 80 springs the two brake assemblies 40, 50 away from opposite sides of the object 70 to release the brake of the object 70.

In summary, the single-cylinder double-acting caliper of the present invention only needs to have a set of cylinder chambers and pistons, so as to achieve the double-acting brake effect of the two brake assemblies, the structure is simple, lightweight, easy to prepare, simple and fast, and convenient for rapid quantity. The production rate is low, the manufacturing cost is low, and the combination is simple and competitive.

In summary, the overall structural design, practicality and efficiency of this creation are indeed in full compliance with the needs of industrial development, and the disclosed structural creation is also an unprecedented innovative structure, so it has a "novelty" should Undoubtedly, this creation can be more effective than the conventional structure. Therefore, it is also "progressive". It fully complies with the requirements of the application requirements for the creation of patents in the Chinese Patent Law. It is a patent application in accordance with the law, and please The bureau will review it early and give it affirmation.
