Multifunctional brake aid

Abstract

The invention provides a multifunctional brake aid, which belongs to the technical field of hydraulic brake. The brake aid is formed by overlaying four main parts, a body is provided with a first-layer cross passage, three pistons and a pressure retaining device are mounted in the passage, the main piston is mounted in the upper middle of the passage, a pressure retaining valve assembly is mounted on the lower portion of the passage, and the left piston and the right piston are mounted on the left and the right of the passage. A second-layer double-attraction coil assembly is mounted above the body, a third-layer vacuum device assembly is mounted above a second-layer casing, a vacuum adjustor assembly is mounted on the left of a shell of a vacuum device, and a fourth-layer contactor assembly is mounted above the vacuum device. A long thrust rod is fixed to the upper middle of the main piston, and the upper end of the thrust rod is inserted into the contactor to drive an upper contact. The multifunctional brake aid has the advantages of reasonable structure, safety and reliability in use, convenience in mounting, low in processing cost and long in service life.

AI Technical Summary

Problems solved by technology

[0002] The brake systems of construction machinery and automobile transportation often use hydraulic brakes, such as hoist brakes and slewing mechanism brakes for hoisting machinery, industrial and mining equipment loaders, forklifts, road rollers, automobiles and aircraft brakes in transportation often use hydraulic brakes. , There are many disadvantages in hydraulic braking, the braking process is slow, and the release of the brake is easy to drag, which will lead to an increase in the loss of brake friction plates and brake wheels, especially for cars that use hydraulic braking. : 1. The parking brake is usually only designed as a manual brake for the rear two wheels. The pull mechanism is designed inside the wheel hub. The driving process is affected by the road surface and the cable is damaged or the spring leaf and the ejector rod fall into the wheel hub. or cause mechanical damage and traffic jams, or cause personal injury or death

2. There is often one more action in the process of starting and stopping. First of all, it is necessary to release the cumbersome process of the parking brake. This process is not only easy to forget, but also wastes time and distracts energy, and will also lead to increased mechanical loss and fuel waste.

3. When the road surface is uneven, the vehicle automatically moves forward and backward, which is prone to crashes and traffic accidents

4. The maintenance of the brake system is difficult and the manufacturing cost is high

5. The maintenance process is likely to cause environmental pollution. The air exhaust process is not only time-consuming but also requires the cooperation of many people. The discharge of oil, gas and liquid is not only difficult to receive but also harmful to people, which wastes time and increases costs.

6. When driving on the expressway, if there is oil leakage from individual brake wheels, the braking process of the vehicle is prone to deviation and accidents. The oil leakage of one wheel brake will affect the braking effect of all wheels, and the light ones cannot walk, and the heavy ones will cause traffic accidents.

7. The existing auto parts are not universal. Once the parts are damaged, they have to go to the monopoly stickers to purchase, which not only takes a long time but also costs a lot

8. It is too difficult to drive a vehicle on the slope bucket pan mountain road, especially the road excavated by the wind power plant, and accidents are prone to occur

9. There are no emergency measures for parking. Once the hand brake fails, the master cylinder is broken, the engine fails, etc., it is prone to accidents

10. No overload brake anti-lock device, the braking process will lead to increased tire loss

11. No anti-theft function, easy to be stolen

The design of existing brakes is unscientific, unsatisfactory, cumbersome to operate, extremely prone to failure, difficult to maintain, expensive, pollutes the environment, and has high manufacturing costs
