Description

Technical Field

[0001] The present application relates to the technical field of vehicle steering gear installation, and more particularly, to a vehicle steering gear assembly and a vehicle. Background Art

[0002] Since it needs to withstand and output a large torque during operation, a vehicle steering gear is generally installed on the vehicle chassis by a multi-point fixing method. Generally, additional housings or fixing structures are constructed on both sides of the steering gear base body, and a plurality of fixing holes are formed therein for connecting to the vehicle chassis through bolts via these fixing holes.

[0003] However, since the chassis structures of different vehicle models are different, the positions of the steering gear fixing holes adapted thereto also need to be adjusted accordingly. For a known vehicle steering gear, in this case, it is necessary to reconstruct or mold the housing or fixing structure for setting the fixing holes.

[0004] It should be noted that the information disclosed in the above background art section is only used to enhance the understanding of the background of the present disclosure, and thus may include information that does not constitute the prior art known to those of ordinary skill in the art. Summary of the Utility Model

[0005] According to different aspects, one of the purposes of the present application is how to adapt to the change of the steering gear fixing hole position without changing the structure of the steering gear itself.

[0006] In addition, the present application also aims to solve or alleviate other technical problems existing in the prior art.

[0007] According to one aspect of the present application, there is provided:

[0008] A vehicle steering gear assembly includes a steering gear, the steering gear includes a steering gear base body and an output shaft bearing sleeve disposed on one side of the steering gear base body and integrally formed with the steering gear. A first fixing plate is connected to the other side of the steering gear base body, and a second fixing plate is connected to the output shaft bearing sleeve.

[0009] Wherein, an installation plate is further included, the installation plate is installed on the steering gear and includes a first area on the side of the first fixing plate and a second area on the side of the second fixing plate. A first installation hole is provided in the first area, and a second installation hole is provided in the second area. The steering gear is fixed to the vehicle through the installation plate via the first installation hole and the second installation hole.

[0010] According to another aspect of the present application, the present application provides a vehicle, which includes the above-mentioned vehicle steering gear assembly, and the vehicle steering gear assembly is installed on the vehicle chassis through the installation plate.

[0011] The advantages of the present application include:

[0012] The steering gear assembly of the present application introduces an additional mounting plate connected to the steering gear, transferring the fixing holes between the steering gear and the vehicle chassis from the steering gear itself to the mounting plate. The steering gear only needs to be connected to the mounting plate, without changing the structure of the steering gear housing or the fixing plate to adapt to the change in the position of the fixing holes, saving the cost of remanufacturing the steering gear mold, shortening the manufacturing cycle of the steering gear, and further strengthening the connection between the steering gear and the vehicle chassis through the introduction of the mounting plate to adapt to the structural requirements of different types of vehicle chassis.

[0017] It is easily understood that according to the technical solution of the present application, without changing the essential spirit of the present application, those of ordinary skill in the art can propose various interchangeable structural ways and implementation ways. Therefore, the following detailed embodiments and the accompanying drawings are only exemplary descriptions of the technical solution of the present application, and should not be regarded as the whole of the present application or as a limitation or restriction on the technical solution of the present application.

[0018] The orientation terms such as up, down, left, right, front, back, front side, back side, top, bottom, etc. mentioned or possibly mentioned in this specification are defined relative to the structures shown in the respective drawings, and they are relative concepts. Therefore, they may change accordingly according to their different positions and different usage states. So, these or other orientation terms should not be construed as restrictive terms. In addition, the terms "first", "second", "third", etc. or similar expressions are only used for descriptive and differentiating purposes, and cannot be understood as indicating or implying the relative importance of the corresponding components or the sequence of components or the assembly sequence.

[0019] Refer to Figure 1, which shows a schematic structural diagram of a vehicle steering gear assembly 10 mounted on a vehicle chassis 20 according to an embodiment of the present application. The vehicle steering gear assembly 10 includes a steering gear 100 and a mounting plate 200. The steering gear 100 is mounted on the vehicle chassis 20 through the mounting plate 200. The steering gear 100 includes a steering gear base 110 and an output shaft bearing sleeve 120. The output shaft bearing sleeve 120 is arranged on one side of the steering gear base 110 and integrally formed with the steering gear 100 in this embodiment. An output shaft needle bearing and an output shaft are arranged in the output shaft bearing sleeve 120 for outputting a steering torque. A first fixing plate 130 is connected to the other side of the steering gear base 110, and a second fixing plate 140 is coupled to the output shaft bearing sleeve 120, especially on the outer peripheral edge of the output shaft bearing sleeve 120. That is to say, the first fixing plate 130 and the second fixing plate 140 are respectively arranged on both sides of the steering gear base 110.

[0020] Reference Figure 2 , which shows a schematic structural diagram of the mounting plate 200 of the vehicle steering gear assembly 10 according to an embodiment of the present application. In this embodiment, the mounting plate 200 is mounted to the steering gear 100 and includes a first region 210 on the side of the first fixing plate 130 and a second region 220 on the side of the second fixing plate 140. That is to say, after the mounting plate 200 is mounted to the steering gear 100, the steering gear base 110 straddles the mounting plate 200, dividing the mounting plate 200 into the first region 210 and the second region 220 which are spaced apart from each other. A first mounting hole 211 is provided in the first region 210, and a second mounting hole 221 is provided in the second region 220. When mounting the steering gear 100, first mount the mounting plate 200 to the steering gear 100, and then fix the mounting plate 200 to the vehicle chassis 20 through the first mounting hole 211 and the second mounting hole 221, for example, through corresponding mating mounting holes provided on the vehicle chassis 20. Through this arrangement and mounting method, the steering gear 100 can be mounted on the vehicle chassis 20 through the mounting plate 200, and mounting holes adapted to the vehicle chassis 20 are provided on the mounting plate 200 without changing the structure of the steering gear 100 itself, and it can also ensure that the steering gear 100 is fixed on both sides of the steering gear base 110 at the same time.

[0021] In an embodiment of the present application, a first through hole 131 is provided in the first fixing plate 130, and a second through hole 141 is provided in the second fixing plate 140. The number of the first through holes 131 is the same as the number of the first mounting holes 211, and the number of the second through holes 141 is the same as the number of the second mounting holes 221. The relative positions of the second through holes 141 with respect to each other are the same as the relative positions of the second mounting holes 221 with respect to each other. In this embodiment, through holes are provided on both the first fixing plate 130 and the second fixing plate 140. It should be understood that in the absence of the mounting plate 200, the steering gear 100 can be connected to the vehicle chassis through the through holes provided on the first fixing plate 130 and the second fixing plate 140, and in this case, the through holes are the mounting holes. Therefore, in this embodiment, the steering gear 100 can be directly connected to the vehicle chassis 20 in another case. Thus, the number of the through holes on the first fixing plate 130 and the second fixing plate 140 matches the number of the first mounting holes 211 and the second mounting holes 221. For the second mounting holes 221, although the positions of the mounting holes change for different vehicle chassis 20, the relative positions of the second mounting holes 221 with respect to each other always remain unchanged. Therefore, the relative positions of the second through holes 141 with respect to each other are the same as the relative positions of the second mounting holes 221 with respect to each other.

[0022] In an embodiment of the present application, a first mating through hole 231 corresponding to the position of the first through hole 131 and a second mating through hole 241 corresponding to the position of the second through hole 141 are provided on the mounting plate 200. The first through hole 131 and the first mating through hole 231, and the second through hole 141 and the second mating through hole 241 are connected by bolts.

[0023] In an embodiment of the present application, the number of both the first through holes 131 and the first mounting holes 211 is 1, and the number of both the second through holes 141 and the second mounting holes 221 is 3. The triangle formed by the second through holes 141 is congruent to the triangle formed by the second mounting holes 221.

[0024] In this embodiment, the number of the second mounting holes 221 is 3 and they are distributed in a triangular shape. The triangle formed by the second through holes 141 is congruent to the triangle formed by the second mounting holes 221. That is to say, with respect to the second mounting holes 221, the relative positions of the second through holes 141 with respect to each other do not change, but the overall position of the second through holes 141 changes.

[0025] In an embodiment of the present application, the mounting plate 200 is welded to the steering gear 100 or the mounting plate 200 is integrally formed with the steering gear 100. In this embodiment, there is no need to connect the steering gear 100 and the mounting plate 200 by providing connection through-holes in the first fixing plate 130 and the second fixing plate 140. Instead, the mounting plate 200 is directly welded to the steering gear 100 or the mounting plate 200 is integrally formed on the steering gear 100 directly during the manufacture of the steering gear 100. This way further simplifies the process flow.

[0026] In an embodiment of the present application, both the first mounting hole 211 and the second mounting hole 221 are configured as elongated holes, and the extending directions of each hole in the second mounting hole 221 are the same.

[0027] In this embodiment, the mounting holes on the mounting plate 200 are configured as elongated holes, such as linear or arc-shaped elongated holes. Thereby, a variety of arrangement ways of the mounting hole positions are provided, and the mounting holes can adapt to a variety of different mating mounting hole positions, so as to adapt to different vehicle chassis types. In the embodiment where the mounting holes are configured as elongated holes, a gasket can be added between the bolt and the mounting plate 200 to increase the friction between the bolt and the mounting plate 200 and strengthen the fixing of the steering gear 100 to the vehicle chassis.

[0028] In an embodiment of the present application, a recess 150 is provided on the side of the second fixing plate 140 facing the mounting plate 200, and a positioning protrusion (not shown in the drawings) matching the shape of the recess 150 is provided at the corresponding position of the mounting plate 200 and the recess 150. Refer to Figure 3 , which shows a schematic diagram of the position of the recess 150 of the steering gear 100 proposed according to an embodiment of the present application. When the mounting plate 200 is mounted on the steering gear 100, the mounting plate 200 abuts against the recess 150 of the steering gear 100. Therefore, the mounting plate 200 can be positioned according to the position of the recess 150 of the steering gear 100, especially by engaging the positioning protrusion into the recess 150 to achieve positioning, so as to facilitate the alignment between the through-hole and the mating through-hole and between the mounting hole and the mating mounting hole, thus facilitating the installation. The positioning protrusion is, for example, provided to be in shape fit with the recess 150. Of course, it can also be provided to match a partial shape feature of the recess 150, such as a single side wall, etc.

[0029] In an embodiment of the present application, in the state where the mounting plate 200 is mounted on the steering gear 100, a support protrusion or a support rib (not shown in the drawings) is provided on the mounting plate 200 along the gravity direction below the first fixing plate 130 and / or the second fixing plate 140.

[0030] In this embodiment, the mounting plate 200 not only serves as an intermediary for fixedly connecting the steering gear 100 to the vehicle chassis, but also plays a role in supporting the steering gear 100 to a certain extent. The steering gear 100 is generally vertically arranged along the direction of gravity on the vehicle chassis 20. If the mounting bolts of the steering gear 100 become loose, it will inevitably cause shaking or even displacement. Support protrusions or support ribs are provided on the mounting plate 200 below the first fixing plate 130 and the second fixing plate 140 along the direction of gravity. For example, support ribs extending along the outer periphery of the first fixing plate 130 and the second fixing plate 140 can support the steering gear 100 by limiting the first fixing plate 130 and the second fixing plate 140. The support protrusions or support ribs can also play a role in positioning the mounting plate 200.

[0031] In an embodiment of the present application, the mounting plate 200, for example, is not only a single mounting plate, but may also include two mounting plates, namely a first mounting plate and a second mounting plate. The first area 210 is provided on the first mounting plate, and the second area 220 is provided on the second mounting plate. In this case, the volumes of both mounting plates are smaller, and the structural design of the mounting plate 200 itself is more flexible.

[0032] It should be understood that in the embodiment of two mounting plates, the first mounting hole and the second mounting hole, or one of them, can also be, for example, long holes. On both mounting plates or one of them, there can also be, for example, corresponding positioning protrusions and support protrusions or support ribs. Regarding their structural features, reference can be made to the above embodiments, and the structure will not be described in detail here.

[0033] On the other hand, the present application also proposes a vehicle, wherein the vehicle includes the vehicle steering gear assembly 10 described above. The vehicle steering gear assembly 10 is mounted on the vehicle chassis 20 through the mounting plate 200, for example, by screwing bolts onto the vehicle chassis 20.

[0034] It should be understood that the steering gear assembly 10 of the present application can be installed on various vehicles, including sedans, trucks, buses, hybrid electric vehicles, pure electric vehicles, etc. Therefore, the subject matter of the present application also aims to protect various vehicles equipped with the steering gear assembly 10 of the present application.

[0035] It should be understood that all the above preferred embodiments are exemplary rather than restrictive. Various modifications or deformations made by those skilled in the art to the specific embodiments described above under the concept of the present application should be within the legal protection scope of the present application.
