Description

Technical Field

[0001] This utility model relates to the field of steering gear bushing technology, specifically to an easy-to-install automotive steering gear bushing. Background Technology

[0002] The steering gear is a key component of the car steering system. Its function is to transmit the force and motion of the driver turning the steering wheel to the steering wheels, enabling the vehicle to move according to the driver's wishes. When the steering gear is working, there is relative movement and friction between the various components inside. In order to ensure the normal operation of the steering gear, extend its service life, and improve the comfort and accuracy of steering, bushings need to be installed between the relevant components. Bushings play an important role in reducing friction, reducing wear, damping shocks, improving steering accuracy, and achieving component positioning and support.

[0003] Steering gears are typically located in compact areas such as inside a vehicle, surrounded by many other components that occupy a lot of space. This makes it very difficult for maintenance personnel to use tools and their hands to install the metal bushings, increasing the difficulty of installation. Utility Model Content

[0004] The purpose of this invention is to provide an easy-to-install automotive steering bushing to solve the problem of difficult installation of steering bushings mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an easy-to-install automotive steering gear bushing, comprising a first bushing and a second bushing located behind the first bushing, and further comprising a convex insert and a slot for connecting the first bushing and the second bushing to each other.

[0006] The first bushing has convex inserts installed on both sides of its rear end, and connecting plates installed on both sides of its top end. Each connecting plate has a lead screw at its front end. The second bushing has slots inside both sides of its front end, and sliding grooves inside both sides of its top end. Sliding rods are installed inside the sliding grooves. Sliding rods are slidably connected to the outer walls of the sliding rods. A fixing spring is fitted on the outer wall of the sliding rod at the rear end of the sliding rod. Each sliding rod has a limit baffle installed at its top end, and a connecting hole is opened inside the front end of each limit baffle.

[0007] Preferably, the slot matches the convex insert, and the convex insert can be inserted into the slot.

[0008] Preferably, the rear ends of the lead screws all pass through the connecting plate, and the rear ends of the lead screws all extend to the rear of the connecting plate.

[0009] Preferably, the lead screw matches the connecting socket, and the lead screw can be inserted into the connecting socket.

[0010] Preferably, the internal parts of the connecting sockets are provided with threads, and the lead screw can be connected to the connecting sockets via threads.

[0011] Preferably, the top of each slider extends above the second bushing, and the limiting baffles can all form a sliding structure through the slider and the sliding rod.

[0012] Preferably, the slider is located inside the groove, and the fixing spring is fixedly installed between the slider and the inner wall of the groove.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: the second bushing is fitted onto the steering shaft, then the first bushing is placed above the second bushing, and the convex insert is inserted into the slot so that the first bushing and the second bushing are flush. Then the limiting baffle is released, and under the reaction force of the fixed spring, the slider slides towards the first bushing, and drives the limiting baffle to be close to the connecting plate. The limiting baffle restricts the convex insert, preventing the convex insert from protruding during vehicle operation. This structure, through the separate design of the first bushing and the second bushing, fits both onto the steering shaft for installation. It can accurately position the components without having to operate in a relatively compact location such as inside the vehicle, thus reducing the difficulty of installation.

[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] Example 1: Please refer to Figure 1-5 An easy-to-install automotive steering bushing includes a first bushing 1 and a second bushing 4 located behind the first bushing 1, and also includes a convex insert 2 and a slot 3 that connect the first bushing 1 and the second bushing 4 to each other.

[0022] The first bushing 1 has convex inserts 2 installed on both sides of its rear end, and connecting plates 6 installed on both sides of its top end. The connecting plates 6 are provided with lead screws 7 at their front ends. The second bushing 4 has slots 3 inside both sides of its front end, and sliding grooves 8 inside both sides of its top end. Sliding rods 9 are installed inside the sliding grooves 8. Sliding sliders 11 are slidably connected to the outer walls of the sliding rods 9. Fixing springs 10 are sleeved on the outer walls of the sliding rods 9 at the rear end of the sliding rods 11. Limiting baffles 5 are installed at the top of the sliding sliders 11. Connecting holes 12 are provided inside the front ends of the limiting baffles 5.

[0023] The slot 3 and the convex insert 2 are matched, and the convex insert 2 can be inserted into the slot 3;

[0024] The rear ends of the lead screws 7 all pass through the connecting plate 6, and the rear ends of the lead screws 7 all extend to the rear of the connecting plate 6;

[0025] The lead screw 7 is matched with the connecting socket 12, and the lead screw 7 can be inserted into the interior of the connecting socket 12;

[0026] The internal parts of the connecting socket 12 are all provided with threads, and the lead screw 7 can be connected to the connecting socket 12 by the threads;

[0027] The top of each slider 11 extends above the second bushing 4, and the limiting baffles 5 can all form a sliding structure through the slider 11 and the slide rod 9.

[0028] The slider 11 is located inside the slide groove 8, and the fixing spring 10 is fixedly installed between the slider 11 and the inner wall of the slide groove 8;

[0029] Specifically, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, when using this mechanism, push the limiting baffle 5 to drive the slider 11, causing the slider 11 to slide away from the first bushing 1 on the outer wall of the slide rod 9, and compress the fixing spring 10. After the first bushing 1 is connected to the second bushing 4, release the limiting baffle 5. Under the reaction force of the fixing spring 10, the slider 11 slides towards the first bushing 1, and drives the limiting baffle 5 to be pressed against the connecting plate 6. The limiting baffle 5 restricts the convex insert 2 to prevent the convex insert 2 from protruding during the car's movement. Then, the operator can pass the lead screw 7 through the connecting plate 6, insert the lead screw 7 into the inside of the connecting socket 12, and rotate the lead screw 7 with a tool to fix the limiting baffle 5 and the connecting plate 6.

[0030] Working principle: During installation, the operator pushes the limiting baffle 5, causing the limiting baffle 5 to drive the slider 11, which slides away from the first bushing 1 on the outer wall of the slide rod 9, compressing the fixing spring 10 and placing the second bushing 4 on the steering gear shaft. Then, the first bushing 1 is placed above the second bushing 4, and the convex insert 2 is inserted into the slot 3, making the first bushing 1 and the second bushing 4 flush. Then, the limiting baffle 5 is released, and under the reaction force of the fixing spring 10, the slider 11 slides closer to the first bushing 1, causing the limiting baffle 5 to be pressed tightly against the connecting plate 6. The limiting baffle 5 restricts the convex insert 2, preventing it from protruding during vehicle operation. Then, the operator can pass the lead screw 7 through the connecting plate 6, inserting the lead screw 7 into the connecting socket 12, and rotate the lead screw 7 with a tool to fix the limiting baffle 5 and the connecting plate 6.
