[0041] Embodiment 1

[0042] The present embodiment relates to a steering gear housing assembly, which is conducive to achieving standardization and common design of parts and components, as well as weight reduction and cost reduction, and further helps to improve the integration, commonality and lightweight level of the entire vehicle.

[0043] In terms of overall structure, Figures 1 to 4 As shown, the steering gear housing assembly of this embodiment includes a steering gear housing 1 and a suspension support 2 arranged on the steering gear housing 1. The suspension support 2 is located on one side of the steering gear housing 1, and at least one suspension bushing 3 is arranged on the suspension support 2, and the suspension support 2 is detachably connected to the steering gear housing 1.

[0044] At this time, as set above, this embodiment can simplify the structure by integrating the suspension bushing 3 on the suspension support 2 and making the suspension support 2 and the steering gear housing 1 detachably connected. Compared with traditional steering gear housing products, it reduces the types and quantities of parts used, which is conducive to the standardization and common design of parts, as well as weight and cost reduction, and further helps to improve the integration, commonality and lightweight degree of the entire vehicle.

[0045] Based on the overall introduction above, in detail, in the specific implementation, the suspension support 2 of this embodiment is integrated with a mounting hole 20 for installing the suspension bushing 3, and the number of the mounting holes 20 and the suspension bushing 3 can be set and adjusted according to the connection requirements between the suspension support 2 and the powertrain or other environmental components, as well as based on the overall NVH (Noise, Vibration, Harshness; noise, vibration and acoustic roughness) performance, operational stability, fatigue durability and other requirements of the suspension system. For example, the mounting hole 20 and the suspension bushing 3 are configured to be one, two or three, etc., integrated on the suspension support 2.

[0046] Furthermore, it is worth mentioning that the suspension bushing 3 of this embodiment, i.e. Figure 4 As shown, it includes an outer tube 31 , an inner tube 32 coaxially arranged in the outer tube 31 , and a rubber body 33 vulcanized and formed between the inner tube 32 and the outer tube 31 .

[0047] In specific implementation, the outer wall of the inner tube 32 is provided with two first protrusions arranged opposite to each other along its own first radial direction, and two second protrusions arranged opposite to each other along its own second radial direction, the first radial direction and the second radial direction are perpendicular, and the rubber body 33 includes a first rubber part connecting each first protrusion and the outer tube 31, and two second rubber parts arranged on the inner wall of the outer tube 31, the two second rubber parts correspond one by one to each second protrusion, thereby facilitating the suspension bushing 3 to have a good buffering effect.

[0048] At the same time, the outer tube 31 is specifically interference fit with the mounting hole 20 on the suspension support 2 to ensure the installation stability between the suspension bushing 3 and the suspension support 2, and the inner tube 32 is used to connect with the powertrain or other peripheral components, for example, it can be specifically screwed.

[0049] Furthermore, the steering gear housing 1 of the present embodiment is generally cylindrical in shape, and may be made of aluminum alloy or ductile iron, and formed by forging or casting processes. The suspension support 2 of the present embodiment is preferably arranged on one side of the steering gear housing 1, and both ends of the steering gear housing 1 are provided with a first opening for the steering rod to pass through, and the steering gear housing 1 is also provided with a second opening for the steering drive shaft to pass through, and the second opening is spaced apart from the suspension support 2. At the same time, the relevant structural parts not mentioned in the steering gear housing assembly of the present embodiment may refer to the various structures in the steering gear products well known to those skilled in the art, and will not be described in detail here.

[0050] In this embodiment, as a preferred implementation form, Figures 1 to 3 As shown, the suspension support 2 is fixed to the steering gear housing 1 through a screw connection structure. Such a configuration can make the suspension support 2 easy to install and operate, and the structural design is simple, which is conducive to the standardization and common design of the steering gear housing 1 and the suspension support 2, as well as subsequent after-sales and maintenance.

[0051] In specific implementation, the screw connection structure of this embodiment can be preferably configured to include a screw connection hole 13 provided on the steering gear housing 1, a screw connection through hole 24 provided on the suspension support 2, and a bolt 4 that passes through the screw connection through hole 24 and is screwed into the screw connection hole 13.

[0052] Of course, the number and arrangement of the above-mentioned screw connection structures can be set and adjusted according to the actual installation and fixing requirements of the suspension support 2. For example, there can be four screw connection structures, and the four screw connection structures can be distributed in a rectangular shape.

[0053] In addition, in this embodiment, in addition to using a screw connection structure to achieve the installation and fixation of the suspension support 2, other assembly forms can also be used, for example, as a preferred implementation form, such as Figures 5 to 9As shown in , an insertion structure and a locking structure are provided between the suspension support 2 and the steering gear housing 1. The suspension support 2 is inserted into the steering gear housing 1 through the insertion structure, and the locking structure locks the suspension support 2 and the steering gear housing 1 together.

[0054] It can be understood that by providing the plug-in structure and the locking structure, a quick-insertion assembly function between the suspension support 2 and the steering gear housing 1 can be achieved, which is beneficial to improving the assembly efficiency of the two.

[0055] In the specific implementation, in this embodiment, as a preferred implementation form, combined with Figure 6 and Figure 7 As shown, the insertion structure includes a slot 21 provided on the suspension support 2 and an insertion protrusion 11 provided on the steering gear housing 1 , and the insertion protrusion 11 is inserted into the slot 21 .

[0056] Here, by mainly forming the insertion structure with the slot 21 and the insertion protrusion 11 , the structure and operation can be made simpler, which is helpful for the integrated and common design of the suspension support 2 and the steering gear housing 1 .

[0057] Secondly, if Figure 7 and Fig. 9 As shown, as a preferred implementation form, the cross section of the slot 21 of this embodiment is "T" shaped, and the cross section of the insertion protrusion 11 is adapted to the slot 21. Thus, a limiting effect can be formed to prevent the insertion protrusion 11 from escaping from the slot 21 in a direction perpendicular to the insertion direction, so as to improve the assembly stability.

[0058] At the same time, in this embodiment, as a preferred implementation form, the slots 21 are arranged at intervals on the suspension support 2, and the number of the insertion protrusions 11 is adapted to the arrangement of the slots 21. The main benefit of this arrangement is that it is conducive to improving the insertion process and the structural stability after insertion.

[0059] In specific implementation, the above-mentioned slots 21 can be preferably arranged to extend along the insertion direction of the suspension support 2 (that is, the length direction of the suspension support 2). The number of the above-mentioned slots 21 can be set and adjusted according to actual insertion requirements. For example, they can be specifically set to two spaced apart, so as to improve the insertion stability while reducing structural design, reducing production and design costs, etc.

[0060] In addition, considering the insertion and positioning requirements of the suspension support 2, in this embodiment, as a preferred implementation form, a positioning structure is provided between the steering gear housing 1 and the suspension support 2, and the positioning structure is used to position the inserted suspension support 2. In this way, the suspension support 2 can be quickly inserted into place, thereby facilitating the convenience of insertion.

[0061] To expand, continue to combine Figure 6 and Figure 7 As shown, as a preferred implementation form, the positioning structure of this embodiment includes a positioning protrusion 12 provided on the steering gear housing 1, and a first positioning surface 22 provided on the suspension support 2, and at the end of the insertion stroke of the suspension support 2, the first positioning surface 22 abuts against the positioning protrusion 12.

[0062] At the same time, in this embodiment, in addition to setting the matching structure of the above-mentioned first positioning surface 22 and the positioning protrusion 12, other structures can also be added to ensure the insertion positioning effect of the suspension support 2. For example, as a preferred implementation form, the positioning structure includes a second positioning surface 111 provided at one end of the insertion protrusion 11, and a positioning matching surface 211 located in the slot 21, and at the end of the insertion stroke of the suspension support 2, the second positioning surface 111 abuts against the positioning matching surface 211.

[0063] As a result, the positioning structure is mainly composed of the positioning protrusion 12 and the first positioning surface 22 that cooperate with each other, and the second positioning surface 111 and the positioning matching surface 211 that cooperate with each other, which can reduce the number of parts used and assembly, and thus help to improve the integration of the suspension support 2 and the steering gear housing 1, as well as the convenience of assembly.

[0064] In addition, in this embodiment, as a preferred implementation form, see Figure 8 and Fig. 9 As shown, the locking structure includes a locking pin 5 arranged in the slot 21 , an elastic member 23 arranged between the locking pin 5 and the bottom of the slot 21 , and a locking hole 112 arranged on the insertion protrusion 11 .

[0065] When the locking pin 5 is aligned with the locking hole 112, the locking pin 5 can be inserted into the locking hole 112 under the elastic push of the elastic member 23. Here, it can be understood that the locking structure is mainly composed of the locking pin 5, the elastic member 23 and the locking hole 112, which can realize automatic locking when the suspension support 2 is inserted in place, which helps to improve the convenience of assembly.

[0066] Of course, in the specific implementation, as a preferred implementation form, the above-mentioned elastic member 23 is preferably a spring, the above-mentioned locking pin 5 is preferably set to match the number of slots 21, and the elastic member 23 and the locking hole 112 are set to match the number of locking pins 5, so as to obtain a better locking effect.

[0067] The steering gear housing assembly of this embodiment, by setting the suspension bushing 3 on the suspension support 2, and detachably setting the suspension support 2 on the steering gear housing 1, uses fewer parts than traditional steering gear housing 1 products, which can help achieve standardization and common design of parts, as well as weight reduction and cost reduction, and further help improve the integration, commonality and lightweight degree of the entire vehicle, thereby helping to improve the quality of the entire vehicle.

[0068] Embodiment 2

[0069] This embodiment relates to a steering gear, which includes the steering gear housing assembly in Embodiment 1. At the same time, this embodiment also relates to a vehicle, which is provided with the above-mentioned steering gear.

[0070] It is worth mentioning that the relevant structural parts not mentioned in the steering gear of this embodiment can refer to the various structures of steering gear products well known to technical personnel in this field, especially the various structures of rack and pinion steering gears. For example, it is based on the steering gear housing assembly in Example 1, and also includes a steering gear and a steering screw arranged in the steering gear housing 1, as well as a steering rod and a steering guard arranged at both ends of the steering gear housing 1.

[0071] And in the specific implementation, the above-mentioned steering gear is preferably arranged on the subframe of the vehicle, and the suspension support 2 integrated on the top of the steering gear housing 1 in Example 1, and the suspension bushing 3 integrated on the suspension support 2, are preferably used as rear suspension to cooperate with the existing left front suspension and right front suspension on the subframe to install the drive axle, and the suspension bushing 3 in Example 1 is preferably screwed and connected to the rear end of the drive axle.

[0072] At this time, as set up above, compared with the traditional technology in which the subframe is connected to the drive axle through a transfer suspension bracket, the types and quantities of suspension system components used can be reduced, which is conducive to reducing the weight and cost of the entire vehicle.

[0073] Furthermore, it can be understood that the suspension support 2 is arranged just above the steering gear in the height direction of the vehicle to form a rear suspension for connecting to the rear end of the drive axle. Compared with the existing structure in which the rear suspension is independently arranged on the subframe, it can reduce the redevelopment investment of the subframe to adapt to the rear suspension interface position, which is beneficial to improving the coordination of systems such as the powertrain, suspension and subframe. At the same time, it can also avoid the relative arrangement clearance requirements between the moving parts connected to the suspension support 2 and the moving parts of the steering gear, which is beneficial to the layout of the vehicle cabin system.

[0074] The steering gear and vehicle of this embodiment, by setting the steering gear housing assembly in the first embodiment, can improve the quality of the entire vehicle based on the integrated, common and lightweight design of the steering gear, so that the entire vehicle has better market competitiveness.

[0075] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
