Description

Technical Field

[0001] This utility model relates to the field of steering tie rod technology, specifically a multi-ball joint linkage steering tie rod. Background Technology

[0002] The steering tie rod is a key component of a car's steering system, directly affecting the vehicle's handling stability, driving safety, and tire lifespan. Its basic principle is that when the driver turns the steering wheel, the steering tie rod converts the rotational motion of the steering rocker arm into the linear motion of the steering knuckle arm, driving the wheels to steer.

[0003] In existing technology, the ball joint of this type of steering tie rod requires lubrication. However, the ball joint of this type of steering tie rod in the existing technology lacks a dedicated lubricant filling interface. This makes it very troublesome for auto mechanics to perform maintenance on the ball joint every time, as they cannot quickly add lubricant to the ball joint as needed. Therefore, an improvement is needed to address this problem by using a multi-ball joint linkage steering tie rod. Utility Model Content

[0004] The purpose of this invention is to provide a multi-ball joint linkage steering tie rod to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a multi-ball-joint linkage steering tie rod, applied to a vehicle steering system. A horizontal connecting rod is movably disposed at the lower end of the vehicle steering system. Both ends of the horizontal connecting rod are provided with tie rod mechanisms for steering the tires. Each tie rod mechanism includes a first slot, a first articulated ball, a steering tie rod, a second slot, and a second articulated ball. The first slot is fixedly disposed at both ends of the horizontal connecting rod. A first articulated ball is movably engaged within the first slot. A steering tie rod is fixedly disposed on one side of the surface of the first articulated ball. A second slot is fixedly disposed at one end of the steering tie rod. A second articulated ball is movably engaged within the second slot. Lubricating oil adding mechanisms are disposed on the outer sides of both the second slot and the vehicle steering system.

[0006] Preferably, the lubricating oil adding mechanism includes a filling port, a sealing ball, a spring, and a connecting hose. The second slot and the outer side of the vehicle steering system are both fixedly provided with filling ports. A sealing ball is movably engaged inside the filling port, and a spring is fixedly provided at the lower end of the sealing ball inside the filling port. A connecting hose is fixedly provided between the filling port and the first slot, and the filling port is interconnected with the inside of the first slot through the connecting hose. The lubricating oil adding mechanism allows lubricating oil to be added to the first and second slots as needed, greatly reducing the difficulty of vehicle maintenance for mechanics.

[0007] Preferably, a first protective sleeve is provided on the surface of the steering tie rod on one side of the vehicle steering system. The first protective sleeve can block dust and protect the first slot and the first articulated ball.

[0008] Preferably, a second protective sleeve is provided on the outer side of the second slot, which can also protect the second slot and the second hinged ball.

[0009] Preferably, the upper outer surface of the filling port is threaded, which allows the filling port to be easily connected to other pipes or pump bodies, thereby facilitating the injection of lubricating oil into the first and second slots.

[0010] Preferably, a connecting screw is fixedly provided on the surface of the second articulated ball, and the connecting screw can be used to fix the second articulated ball and the wheel at a predetermined connection point.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model has additional lubricating oil filling ports at multiple ball joints, which greatly reduces the difficulty of maintenance for auto repair personnel. They can simply use the pump body and external pipes threaded onto the outer surface of the filling port to squeeze the lubricating oil into the ball joint, making it convenient to use.

[0013] 2. Each time lubricating oil is added, the increased oil pressure at the filling port of this utility model can compress the spring, causing the sealing ball to move downward, thus opening the filling port. After filling is completed, the sealing ball can automatically seal the filling port to prevent lubricating oil from being thrown out through the filling port, thereby improving the performance of this device.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-5 This utility model provides a technical solution: a multi-ball-joint linkage steering tie rod 5, applied to a vehicle steering system 1. A horizontal connecting rod 2 is movably arranged at the lower end of the vehicle steering system 1. Both ends of the horizontal connecting rod 2 are provided with tie rod mechanisms for pulling the tires to steer. The tie rod mechanism includes a first slot 3, a first articulated ball 4, a steering tie rod 5, a second slot 6, and a second articulated ball 7. The first slot 3 is fixedly arranged at both ends of the horizontal connecting rod 2. The first articulated ball 4 is movably engaged inside the first slot 3. The steering tie rod 5 is fixedly arranged on one side of the surface of the first articulated ball 4. The second slot 6 is fixedly arranged at one end of the steering tie rod 5. The second articulated ball 7 is movably engaged inside the second slot 6. Both the second slot 6 and the vehicle steering system 1 are provided with a lubricating oil adding mechanism on their outer sides.

[0022] The lubricating oil adding mechanism includes a filling port 8, a sealing ball 9, a spring 10, and a connecting hose 11. The second slot 6 and the outer side of the vehicle steering system 1 are both fixedly provided with filling ports 8. A sealing ball 9 is movably engaged inside the filling port 8. A spring 10 is fixedly installed at the lower end of the sealing ball 9 inside the filling port 8. A connecting hose 11 is fixedly installed between the filling port 8 and the first slot 3, and the filling port 8 is interconnected with the interior of the first slot 3 through the connecting hose 11. The lubricating oil adding mechanism allows lubricating oil to be added to the first slot 3 and the second slot 6 as needed, greatly reducing the difficulty of vehicle maintenance for mechanics.

[0023] The vehicle steering system 1 has a first protective sleeve 12 on the surface of the steering tie rod 5. The first protective sleeve 12 can block dust and protect the first slot 3 and the first hinge ball 4.

[0024] A second protective sleeve 13 is provided on the outside of the second slot 6. The second protective sleeve 13 can also protect the second slot 6 and the second hinged ball 7.

[0025] The upper outer surface of the filling port 8 is provided with a thread 14. The thread 14 allows the filling port 8 to be easily connected to other pipes or pump bodies, thereby facilitating the injection of lubricating oil into the first slot 3 and the second slot 6.

[0026] The second articulated ball 7 is fixedly provided with a connecting screw 14, which can be used to fix the second articulated ball 7 and the preset connection point of the wheel.

[0027] Working principle: When using this device, additional lubricating oil filling ports are provided at multiple ball joints. This greatly reduces the difficulty of maintenance for auto repair personnel. They can simply use the pump body and external pipe to squeeze the lubricating oil into the ball joint through the thread 14 on the outer surface of the filling port 8, making it convenient to use.

[0028] Furthermore, each time lubricating oil is added to the filling port 8 of this device, the increased oil pressure can compress the spring 10 to contract, causing the sealing ball 9 to move downward, thus opening the filling port 8. After the filling is completed, the sealing ball 9 can automatically seal the filling port 8 to prevent the lubricating oil from being thrown out through the filling port 8, thereby improving the performance of this device.
