Description

Technical Field

[0001] This application relates to the field of automotive parts technology, and in particular to an automotive steering gear bracket with a buffer function. Background Technology

[0002] Cars control the direction of the wheels through the steering mechanism. The tie rod, which connects two wheels, is relatively long. To ensure its stability, a support structure is installed on the vehicle chassis. However, since the tie rod and the support structure are mostly in hard contact, the contact stress between them increases when the vehicle travels over bumpy roads. This can accelerate the wear of the tie rod and the support structure, thus increasing the probability of damage. Summary of the Invention

[0003] The purpose of this application is to provide a car steering bracket with a buffer function that can reduce the probability of damage to the steering tie rod.

[0004] To achieve the above objectives, this application provides a car steering gear bracket with a buffer function: including a pair of symmetrical outer sleeves, with an inner sliding sleeve movably connected within the two outer sleeves. The main body of the inner sliding sleeve is a bushing body, which has through holes at both ends, suitable for the steering tie rod of the car steering gear to pass through to form a sliding pair. A buffer ring is provided between the outer side of the bushing body and the inner wall of the outer sleeves to provide non-rigid contact support.

[0005] As a preferred embodiment, each of the outer sleeves includes a top plate with side plates extending in the same direction at both ends. The bushing body is located between the two side plates to form a sliding pair, which allows the steering tie rod to float up and down relative to the vehicle chassis within a certain range, taking into account both installation stability and flexibility of response.

[0006] As a preferred embodiment, the bushing body has a slider on the side facing the side plate, and the end face of the side plate away from the top plate has a groove extending towards the top plate, which is suitable for cooperating with the slider to form a sliding pair to prevent the inner sleeve from disengaging from the outer sleeve.

[0007] As a preferred embodiment, the outer side of the side plate away from the top plate has a connecting plate, and the connecting plate has connecting holes. The number and position of the connecting holes on the two outer sleeves correspond to each other, allowing bolts and other connecting parts to pass through for fixing and connection.

[0008] As a preferred embodiment, the bushing body has a guide groove on the inner wall of the through hole, which is suitable for cooperating with the guide strip structure on the outer side of the steering tie rod, and plays a pre-positioning role during installation, which can improve assembly efficiency.

[0009] As a preferred embodiment, the buffer ring is located between the top plate and the bushing body, providing a buffering effect for the movement of the inner sliding sleeve relative to the outer ferrule.

[0010] As a preferred embodiment, the inner wall of the top plate has a positioning block, and the positioning block has a limiting groove on its end face opposite to the top plate. The buffer ring is locked in the limiting groove to ensure the stability of the buffer ring configuration.

[0011] As a preferred embodiment, there are two buffer rings, located between the two top plates and the bushing body respectively. The buffer rings are made of rubber material and have a deformation cavity in the center to increase the deformation range of the buffer rings, thereby improving the buffering effect.

[0012] Compared with the prior art, the beneficial effects of this application are as follows:

[0013] (1) By setting up an inner sliding sleeve and an outer clamping sleeve structure that cooperate with each other, and setting a buffer ring structure between the inner sliding sleeve and the outer clamping sleeve, the steering tie rod passing through the bracket can not only be stably supported, but also avoid hard contact with the bracket. When the vehicle passes through a bumpy road section, the relative wear between the steering tie rod and the bracket is smaller, and the probability of damage is lower.

[0014] (2) By designing a detachable outer sleeve structure, not only is the installation stability of the inner sliding sleeve guaranteed, but the assembly, disassembly and replacement of the entire bracket are also made more convenient. Attached Figure Description

[0021] The present application will be further described below with reference to specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0022] In the description of this application, it should be noted that the directional terms such as "center", "lateral", "longitudinal", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", and "counterclockwise" indicate the orientation and positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.

[0023] It should be noted that the terms "first," "second," etc., in the specification and claims of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0024] The terms “comprising” and “having”, and any variations thereof, in the specification and claims of this application are intended to cover non-exclusive inclusion, for example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or device.

[0025] like Figure 1-5The car steering gear bracket with buffer function shown includes a pair of symmetrical outer sleeves 2. The outer sleeves 2 are made of corrosion-resistant alloy material, such as lightweight aluminum alloy. An inner sliding sleeve 1 is movably connected inside the two outer sleeves 2. The main body of the inner sliding sleeve 1 is a cuboid bushing body 101. The bushing body 101 has through holes 103 through both ends. The axis of the through holes 103 is parallel to the plane of symmetry of the two outer sleeves 2, which is used for the steering tie rod of the car steering gear to pass through to form a sliding pair. Usually, a guide groove 104 is also opened in the inner wall of the through hole 103 of the bushing body 101, which is used to cooperate with the guide strip structure on the outer side of the steering tie rod. However, it is not to restrict the rotation of the steering tie rod relative to the bushing body 101, but only to provide a pre-positioning function during installation.

[0026] The two outer sleeves 2 have the same structure. Each outer sleeve 2 includes a flat top plate 201. The top plate 201 has side plates 202 extending in the same direction at both ends. The side plates 202 are perpendicular to the top plate 201. The bushing body 101 is located between the two side plates 202 to form a sliding pair, which restricts the degree of freedom of movement of the inner sleeve 1. In fact, the side of the bushing body 101 facing the side plate 202 also has a slider 102. The end face of the side plate 202 away from the top plate 201 has a groove 206 extending towards the top plate 201, which cooperates with the slider 102 to form a sliding pair. In this way, the inner sleeve 1 will be more stable when making buffering movements.

[0027] Although the movable inner sleeve 1 can provide a certain cushioning effect, the cushioning effect is not obvious due to the lack of support. Therefore, a buffer ring 3 is also provided between the outer side of the bushing body 101 and the inner wall of the outer sleeve 2. In fact, the buffer ring 3 is located between the top plate 201 and the bushing body 101. The inner wall of the top plate 201 has a positioning block 203. The end face of the positioning block 203 facing away from the top plate 201 has a limiting groove 204. The buffer ring 3 is stuck in the limiting groove 204. The compressed buffer ring 3 can be kept stable in the limiting groove 204. There are two buffer rings 3, located between the two top plates 201 and the bushing body 101 respectively. They are symmetrically arranged about the bushing body 101. The buffer ring 3 is made of rubber material and has good elasticity. In addition, the buffer ring 3 also has a deformation cavity 301 in the center, which can increase the deformation range of the buffer ring 3, thereby improving the cushioning capacity.

[0028] The outer side of the side plate 202 away from the top plate 201 has a connecting plate 205. The connecting plate 205 is perpendicular to the side plate 202 and parallel to the top plate 201. The connecting plate 205 is also provided with connecting holes 207. Each connecting plate 205 has at least two connecting holes 207. The number and position of the connecting holes 207 on the two outer sleeves 2 correspond, allowing bolts and other connecting parts to pass through and constrain the two outer sleeves 2 together, and then connect them to the vehicle chassis.

[0029] Working principle: During installation, first, the steering tie rod is passed through the through hole 103 of the inner sliding sleeve 1. Then, the two buffer rings 3 are respectively placed into the limiting grooves 204 of the two outer sleeves 2. The two outer sleeves 2 are fastened to the outside of the bushing body 101, and the buffer rings 3 are squeezed and deformed along the extension direction of the slider 102. Then, the connecting plates 205 are fastened together with bolts. Finally, a longer bolt structure is used to pass through the connecting hole 207 to connect the outer sleeves 2 to the vehicle chassis. During vehicle operation, if the vehicle steering gear moves relative to the chassis, the buffer rings 3 can suppress this relative movement, so that the vehicle steering gear remains relatively stable, thereby providing better protection for the steering control of the vehicle on bumpy roads.

[0030] The basic principles, main features, and advantages of this application have been described above. Those skilled in the art should understand that this application is not limited to the above embodiments. The embodiments and descriptions in the specification are merely the principles of this application. Various changes and modifications can be made to this application without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection claimed by this application is defined by the appended claims and their equivalents.
