Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of transportation equipment, and in particular to a device for realizing rapid braking of a truck in an emergency, aiming to improve the driving safety and emergency response capability of the truck. Background Art
[0002] In long-distance transportation or complex road conditions, trucks have heavy loads and large inertia. When faced with emergencies, such as sudden obstacles in front or the need for emergency avoidance, traditional braking systems may not be able to quickly and effectively reduce vehicle speed, thereby increasing the risk of traffic accidents. Traditional truck braking systems mainly rely on wheel brakes to generate braking force through friction to reduce vehicle speed. However, this braking method may have problems such as long braking distance and unstable braking effect in emergency situations.
[0003] In order to solve the above problems, some truck emergency brake assist devices have appeared on the market, such as electronic stability control system ESC, automatic emergency braking system AEB, etc. These systems monitor the vehicle status and surrounding environment through sensors, and automatically activate the brake device to reduce the speed when potential danger is detected. However, these systems are usually expensive and have high requirements for vehicle hardware and software, and are not suitable for all types of trucks.
[0004] Therefore, it is particularly important to develop a truck emergency brake device that is low-cost, easy to install, and can respond quickly and brake effectively in an emergency.
[0005] Prior art comparison documents:
[0006] Comparative Document 1: A truck auxiliary braking device, including a pneumatic braking system and a manual control valve. The device adjusts the pressure of the pneumatic braking system through the manual control valve to achieve braking of the truck wheels. However, the device requires the driver to manually operate it in an emergency, which takes a long time to react, and the braking effect is affected by the driver's operating proficiency.
[0007] Comparative Document 2: A truck electronic braking system, including sensors, controllers and actuators. The system monitors the vehicle status through sensors, and when an emergency is detected, the controller automatically activates the actuator to brake the wheels. Although the system can automatically respond to emergencies, it is expensive and has high requirements for vehicle hardware and software. Summary of the invention
[0008] The purpose of the present invention is to provide an emergency brake device for trucks, which can be quickly activated in an emergency situation, and push the brake pads to fit tightly against the wheels through a hydraulic transmission system to achieve rapid braking, effectively shorten the braking distance, and improve driving safety.

[0019] The present invention is further described in detail below in conjunction with the accompanying drawings.
[0020] When the present invention is implemented, the truck emergency brake device of the present invention includes a truck head 1, which is characterized by:
[0021] An operating switch 2 is provided inside the front of the truck 1: the operating switch 2 is used to activate the braking device in an emergency, which is convenient for the driver to operate quickly.
[0022] The front of the truck is connected to a carriage 3 : the carriage 3 is the main part for transporting goods and is connected to the front of the truck 1 to form a complete truck structure.
[0023] A motor 4 is provided at one end of the compartment 3 near the front end 1 of the truck. The motor 4 is used as a power source to drive the oil pump 5 to work.
[0024] The motor 4 is connected to the oil pump 5: the oil pump 5 is responsible for extracting the hydraulic oil from the hydraulic oil tank 6 and pressurizing it. An engine or a high-pressure motor can also be used to pump the oil.
[0025] The oil pump 5 is connected to the hydraulic oil tank 6 : the hydraulic oil tank 6 stores hydraulic oil and provides sufficient hydraulic medium for the oil pump 5 .
[0026] An oil outlet 7 and an oil inlet 8 are provided on the top of the oil pump 5: the oil outlet 7 outputs high-pressure hydraulic oil, and the oil inlet 8 sucks low-pressure hydraulic oil.
[0027] The oil outlet 7 and the oil inlet 8 are connected to the hydraulic top 10 via an oil pipe 9 : the oil pipe 9 serves as a transmission channel for the hydraulic oil to deliver the high-pressure hydraulic oil to the hydraulic top 10 .
[0028] A hydraulic rod 11 is provided inside the hydraulic top 10 . The hydraulic rod 11 extends or retracts under the action of high-pressure hydraulic oil to generate thrust or pulling force.
[0029] A movable shaft 12 is provided at the end of the hydraulic rod 11 : the movable shaft 12 allows the thrust direction of the hydraulic rod 11 to be adjusted to a certain extent to meet different braking requirements.
[0030] A top plate 13 is hinged on the movable shaft 12: the top plate 13 is pushed by the hydraulic rod 11 and can move in multiple directions through the hinged action of the movable shaft 12 to avoid breaking.
[0031] A brake pad 14 is provided at the bottom of the top plate 13 : the brake pad 14 contacts the ground and generates friction to achieve braking.
[0032] The movable shaft 12 is connected to the movable shaft 2 16 via a connecting rod 15. The arrangement of the connecting rod 15 and the movable shaft 2 16 enhances the stability and reliability of the top plate 13 and the brake pad 14 during the braking process.
[0033] The movable shaft 2 16 is mounted on a support seat 17 : the support seat 17 provides support for the movable shaft 2 16 to ensure its stable position during the braking process.
[0034] The support seat 17 is arranged on one side of the rear wheel of the carriage 3 close to the rear of the carriage: such a layout enables the brake pad 14 to directly act on the ground behind the wheel to achieve an effective braking effect.
[0035] Further technical features include:
[0036] The brake pad 14 is made of high temperature resistant and wear resistant material, which ensures that the brake pad 14 can still maintain good braking performance under long-term high temperature and friction.
[0037] There are two hydraulic tops 10 and hydraulic rods 11, which are arranged on both sides of the brake pad 14. This design makes the braking force more uniform and improves the stability and efficiency of braking.
[0038] The top plate 13 and the brake pad 14 are fixedly connected to ensure that the brake pad 14 will not fall off or shift during the braking process, thereby ensuring the reliability of the braking.
[0039] The oil pump 5 and the hydraulic oil tank 6 are bidirectionally connected via pipelines: the hydraulic oil is allowed to circulate between the oil pump 5 and the hydraulic oil tank 6, thereby improving the efficiency and stability of the hydraulic system.
[0040] The hydraulic top 10 is installed on the rear bridge of the carriage: such a layout enables the hydraulic top 10 to act on the wheels more directly, thereby improving the response speed and effect of braking.
[0041] The working principle of the present invention is as follows: in an emergency, the driver presses the operating switch 2, the motor 4 starts and drives the oil pump 5 to work. The oil pump 5 extracts hydraulic oil from the hydraulic oil tank 6, and delivers the high-pressure hydraulic oil to the hydraulic top 10 through the oil outlet 7 and the oil pipe 9. The hydraulic rod 11 in the hydraulic top 10 extends under the action of the high-pressure hydraulic oil, pushing the top plate 13 and the brake pad 14 to move toward the wheel. The brake pad 14 generates friction after contacting the wheel, thereby achieving rapid braking.
[0042] Example:
[0043] Embodiment 1:
[0044] A specific implementation of a truck emergency brake device is as follows: an operating switch 2 is provided inside the truck head 1, and a motor 4 and an oil pump 5 are provided inside the car body 3 at one end near the car head, and the oil pump 5 is connected to the hydraulic oil tank 6. The oil outlet 7 and the oil inlet 8 are respectively connected to the hydraulic top 10 through oil pipes 9, and the hydraulic top 10 is installed on the rear bridge of the car body. The middle of the hydraulic top 10 is fixed with a movable shaft, and it is balanced with the ground when it is folded to avoid hanging on things. The hydraulic rod 11 inside it is hinged to the top plate 13 through the movable shaft 12, and the bottom of the top plate 13 is provided with a brake pad 14. In an emergency, the driver presses the operating switch 2, the motor 4 starts and drives the oil pump 5 to work, and the high-pressure hydraulic oil is delivered to the hydraulic top 10, pushing the hydraulic rod 11 to extend, and then pushing the top plate 13 and the brake pad 14 to move toward the ground to achieve rapid braking.
[0045] Embodiment 2:
[0046] Another specific implementation of the truck emergency brake device is as follows: similar to the first embodiment, but different in the design of the hydraulic top 10. In this embodiment, the hydraulic top 10 adopts a double-acting hydraulic cylinder, that is, the hydraulic rod 11 can be extended or retracted under the action of high-pressure hydraulic oil. In this way, after emergency braking, when the brake needs to be released, the hydraulic oil can be pumped out of the hydraulic top 10 by controlling the oil pump 5 to work in reverse, so that the hydraulic rod 11 is retracted, thereby releasing the braking effect of the brake pad 14 on the ground. This design improves the flexibility and practicality of the device.
