Description

Technical Field

[0001] The utility model belongs to the technical field of large-scale equipment braking, relates to a braking system, and specifically relates to a braking system that can be used for multiple combinations. Background Art

[0002] The brake system is an essential part of moving or rotating equipment, and plays a very important role in the safe and normal use of the equipment. The brake force mainly comes from manpower and vacuum booster pumps, which are then transmitted through hydraulic and air pressure. There are two main ways of power transmission: hydraulic servo brake system and pneumatic brake system. The hydraulic servo brake system has fast and accurate braking response, is easy to operate, and is easier to integrate into high-speed driving systems, but has low power and cannot be used in heavy trucks; the pneumatic brake system has high power and is mostly used in heavy trucks, but because the gas is easily compressed, the response time is longer.

[0003] The execution end is mainly based on traditional mechanical brakes. In terms of service braking: disc / drum brakes are the final actuators for vehicle braking. The principle is to use the non-rotating parts connected to the body and the rotating parts connected to the wheels to generate friction to consume the kinetic energy of the tires. Disc brakes have good heat dissipation and high reliability and are widely used in passenger cars. In terms of parking brakes, mechanical cable hand brakes are mostly used. A steel pull rope is used to apply tension to the brake disc, thereby tightening the wheel to achieve parking braking. Summary of the invention

[0024] It should be noted that, unless otherwise specified, all devices and components in the present invention are devices and components known in the prior art.

[0025] The following are specific embodiments of the present invention. It should be noted that the present invention is not limited to the following specific embodiments, and all equivalent changes made on the basis of the technical solution of the present application fall within the protection scope of the present invention.

[0026] Example:

[0027] This embodiment provides a brake system that can be used in multiple combinations, such as Figure 1 As shown, it includes a brake platform 1, a brake platform 3 is installed vertically above the brake platform 1 in parallel through a pair of vertically arranged rotating shafts 2, a brake rocker arm 4 is installed on the pair of rotating shafts 2 respectively, and the pair of brake rocker arms 4 are located between the brake platform 3 and the brake platform 1 and can rotate around the rotating shafts 2;

[0028] like Figure 1 As shown, the right ends of a pair of brake rocker arms 4 are rotatably connected to cylinder contacts 6 arranged at both ends of the same cylinder 5 in a one-to-one correspondence, and a longitudinally arranged return spring 7 is also installed between the pair of brake rocker arms 4, and the return spring 7 is located between the brake platform 3 and the cylinder 5;

[0029] like Figure 1 As shown, a brake block 8 is rotatably mounted on the lateral left end of a pair of brake rocker arms 4. The pair of brake blocks 8 are used to clamp a brake flywheel 9, and the brake flywheel 9 is mounted on a longitudinally arranged rotating shaft 10.

[0030] As a preferred solution of this embodiment, Figures 2 to 5 As shown, multiple combinations of brake systems that can be used for multiple combinations include at least one arrangement of a single rotating shaft on one side, a single rotating shaft on opposite sides, a single rotating shaft on opposite sides with a shared brake flywheel, or a combination of more than one arrangement.

[0031] As a preferred solution of this embodiment, the cylinder 5 is fixedly mounted on the brake platform 1 .

[0032] As a preferred solution of this embodiment, an air inlet 11 and an air outlet 12 are provided on the cylinder 5 .

[0033] As a preferred solution of this embodiment, the brake block 8 is located outside the lateral left end of the brake platform 1.

[0034] The working process of the brake system of the utility model which can be used for multiple combinations is as follows:

[0035] First, the parking brake:

[0036] like Figure 1 As shown, in the initial state, since the reset spring 7 pre-tensions the brake rocker arm 4, the brake flywheel 9 can rotate freely. When high-pressure air is introduced into the air inlet 11 of the cylinder 5, the high-pressure air pushes the cylinder contact 6 to drive the brake rocker arm 4 and the brake block 8 to brake. Under the action of the large clamping force, the brake flywheel 9 is tightly clamped and kept stationary. At the same time, the rotating shaft 10 and the brake flywheel 9 are fixedly connected, thereby realizing the parking brake.

[0037] Second, rapid braking:

[0038] like Figure 1 As shown, in the initial state, the rotating shaft 10 maintains high-speed rotation to drive the brake flywheel 9 to rotate. When a situation requires rapid braking, high-pressure gas is quickly filled into the cylinder 5, and the brake rocker arm 4 drives the brake block 8 to quickly clamp the brake flywheel 9, allowing the brake flywheel 9 to quickly slow down.

[0039] Third, parking brake:

[0040] like Figure 1 As shown, by effectively controlling the PID (proportional, integral and differential) of the intake pressure of the cylinder 5, the braking force is effectively controlled to achieve parking brake.

[0041] Fourth, realize single-axis multi-combination layout:

[0042] like Figure 2 As shown, two or more braking systems are arranged on one side of a single rotating shaft, which can achieve greater braking force and more diverse braking force control; Figure 3 As shown, a single rotating shaft is arranged on opposite sides, and multiple braking systems can also be arranged; Figure 4 As shown, the arrangement of shared brake flywheels on opposite sides of a single rotating shaft is also an option.

[0043] Fifth, realize multi-axis and multi-combination layout:

[0044] like Figure 5 As shown, multiple braking systems are arranged on multiple rotating shafts to achieve various combinations, which greatly reflects the advantages of the utility model in terms of flexible arrangement, large braking force and flexible control.
