Description

Technical Field

[0001] The present invention relates to the technical field of automobile manufacturing processes, and in particular to a wheel side module, a Y-direction expansion method, and an automobile. Background Art

[0002] "Automobile architecture" is the current mainstream design direction. The automobile architecture evolves from the platform. When there are too many automobile platforms of an automobile enterprise, it will also cause an increase in R & D costs. If a connection can be established between platforms, the role of the platform can be better exerted. The architecture is based on the platform itself and provides an architectural system for engineering design solutions and modular manufacturing at a higher level, running through links such as production, R & D, and products. It can be said that the architecture has higher extensibility and modular characteristics.

[0003] However, at present, no systematic elaboration has been given on the expansion strategy for architecture or platform-based models. Most of them are conceived as internal technical solutions of enterprises, and most structures cannot apply a unified expansion strategy and all require re-formulating solutions, especially for the wheel side module, resulting in low development efficiency and lack of generality in structure.

[0004] In view of this, the present invention is specifically proposed. Summary of the Invention

[0056]

General inventive concept

[0057] Therefore, based on the technical problems existing in the prior art, this solution specifically proposes a modular wheel-end module 1000, aiming to solve the above technical problems.

[0058] Please refer to Figure 1 , Figure 1 which is a schematic diagram showing the structure of the wheel-end module 1000 that can be expanded in the Y direction in an exemplary manner in an embodiment of the present invention.

[0059] As can be seen from the figure, in an embodiment of the present invention, the wheel-end module 1000 includes a knuckle 100, a control arm 200, and a rim 300;

[0060] Among them, the knuckle 100 is a hinge for wheel steering, and the control arm 200 and the hub 300 are connected through the knuckle.

[0061] In a general inventive concept, the knuckle 100, the control arm 200, and the rim 300 are arranged vertically. One side of the knuckle 100 is connected to the rim 300 through a hub bearing, and the other side is connected to at least the control arm ball joint of the control arm 200. The specific connection method can be referred to as follows.

[0062] A preset machining allowance is set on at least one of the structures at the connection between the steering knuckle 100 and the rim 300 and / or the structure at the connection between the steering knuckle 100 and the control arm ball pin, so as to control the relative distance between the wheel hub bearing and the control arm ball pin to achieve Y-direction expansion.

[0063] The control arm 200 can control the length of its effective arm length 230, thereby achieving Y-direction expansion.

[0064] The rim 300 can control the ET value (Off-set value), that is, the deviation between the mounting surface of the rim 300 and the center of the wheel rim, to achieve expansion in the Y direction.

[0065] For the specific connection relationship, please refer to the figure. From the left side, the wheel module is the rim 300, the steering knuckle 100, and the control arm 200. One side of the steering knuckle 100 is connected to the rim 300 through the hub bearing, and the other side is connected to the suspension, the control arm 200, etc., for transmitting and bearing the front (or rear) load of the car, supporting and driving the front (or rear) wheel to rotate around the kingpin to turn the car. When the car is in motion, the steering knuckle 100 is used to bear variable impact loads.

[0066] Through the above general inventive concept, according to the design of the above structure, a Y-direction expansion plan can be formulated and a fixed strategy or strategy combination can be formed. For each strategy, the bandwidth is given in combination with the motion gap and the performance boundary, which can form internal enterprise specifications or standards, improve the work efficiency in the pre-research stage of the platform architecture, and reduce development risks.

[0067] The steering knuckle 100 is vertically arranged and one side is connected to the rim 300 via the wheel hub bearing, and the other side is connected to at least the control arm ball pin of the control arm 200; wherein, a preset machining allowance is set on at least one of the structures at the connection between the steering knuckle 100 and the rim 300, and / or the structure at the connection between the steering knuckle 100 and the control arm ball pin, so as to control the relative distance between the wheel hub bearing and the control arm ball pin to achieve Y-direction expansion.

[0068] The following is a detailed description of each component:

[0069]

Steering knuckle 100

[0070] Please refer to Figure 2 (a-b) and Figure 3 (a-b). Figure 2a It is a schematic structural diagram showing an embodiment of the present invention, exemplarily showing a wheel side module 1000 that can be expanded in the Y direction when the steering knuckle 100 is a universal part;

[0071] Figure 2b The wheel side module provided by the embodiment of the present invention Figure 2a the other side of; Figure 3aFIG. 0 is a schematic structural diagram (front view) of the knuckle 100 after machining in the exemplary wheel hub module 1000 that can be extended in the Y direction according to an embodiment of the present invention. Figure 3b In the embodiment of the present invention Figure 3a is a cross-sectional view taken along line A-A in FIG.

[0072] In the embodiment of the present invention, for the sake of distinction, the knuckle before machining of the casting or forging is denoted as knuckle 100', and the knuckle that has undergone hole machining and post-processing and is ready for use is denoted as knuckle 100.

[0073] The knuckle has a double-arm fork-shaped structure as a whole before and after machining, which includes a first surface 101 and a second surface 102 that are opposite to each other, wherein the first surface 101 faces the wheel hub side, and the second surface 102 faces away from the wheel hub.

[0074] First, refer to Figure 2a ~ Figure 2b . On the first surface 101, there is at least one first mounting surface 110' for connecting the wheel hub bearing (similarly, 110' is used before machining and 110 is used after machining). On the first mounting surface 110', there are a first connecting arm 120' and a second connecting arm 130' that extend outward relative to the second surface 102 (in the direction away from the wheel hub). The regions where the first connecting arm 120' and the second connecting arm 130' protrude outward are used for machining connection holes for connecting the control arm ball pin.

[0075] Further, at the front and rear sides of the knuckle 100', on one side, there is a side ear 140' for horizontally connecting the caliper, and on the other side, there is a third connecting arm 150' for vertically connecting the tie rod. Among them, there is a remaining space on the first side ear 140' and the third connecting arm 150' for machining holes respectively.

[0076] In the embodiment of the present invention, the morphology of the first mounting surface 110' is to protrude a preset distance relative to the first surface 101. This distance can be used to perform different milling amounts on the first mounting surface 110' according to different wheel gauges to control the relative distance between the wheel hub bearing and the control arm ball pin.

[0077] The outer surface of the first mounting surface 110' is a plane, which is convenient for machining and cutting.

[0078] Combined with FIGS. 2(a - b) and continue to refer to Figure 3a to Figure 3bAfter processing, the first connecting arm 120′ and the second connecting arm 130′ are provided with the first reference hole 120 and the second reference hole 130 for connecting the control arm ball pin. The first reference hole 120 and the second reference hole 130 are through holes penetrating the first connecting arm 120′ and the second connecting arm 130′, wherein the first reference hole 120 is connected to the outer ball pin of the upper control arm, and the second reference hole 130 is connected to the outer ball pin of the lower control arm.

[0079] At the same time, the first mounting surface 110 after milling is a plane, and a first through hole 103 is arranged on the first mounting surface 110 which runs through the entire steering knuckle 100, wherein the horizontal distance between the first mounting surface 110 and the center of the upper surface axis of the first reference hole 120 is the relative distance △Y1 between the wheel hub bearing and the outer ball pin of the control arm.

[0080] It can be understood that by performing milling on the first mounting surface 110 to reduce the thickness of the first mounting surface 110 , the relative distance △Y1 between the wheel hub bearing and the outer ball pin of the control arm can be changed.

[0081]

Control arm 200

[0082] See also Figures 4 - 5 , Figure 4 is a schematic structural diagram showing an exemplary embodiment of the present invention showing a control arm 200 in a connected state; Figure 5 It is a schematic diagram of the structure of the control arm 200 in the wheel side module 1000 provided in an embodiment of the present invention.

[0083] The control arm 200 is a fork-shaped structure, with one arm of the control arm 200 extending to one side and the other two arms extending to the other side, wherein two coaxial longitudinal holes 201 are provided at the ends of the two arms, and an outer arm hole 202 is provided at the end of the other arm.

[0084] The outer hole 202 of the arm is connected to the first reference hole 120 of the steering knuckle 100 through the outer ball pin of the control arm, and the longitudinal axis hole 201 is connected to the longitudinal beam respectively, which can be used as a guide and force transmission element of the automobile suspension system to transmit various forces acting on the wheel to the body, while ensuring that the wheel moves along a certain trajectory.

[0085] In the embodiment of the present invention, the first axis 220 of the longitudinal axis hole 201 and the second axis 230 of the arm outer hole 202 are set at an angle, and the specific angle can be adaptively configured according to needs.

[0086] On one side of the arm outer hole 202 is the arm outer point 210, and the size of the second axis 230 (effective arm length) passing through the control arm outer point 210 and perpendicular to the first axis 220 can be changed, that is, △Y2, and the effective arm length of the control arm 200 of different vehicle models is adjusted within the bandwidth range. That is, according to the different wheelbases, the relative distance between the arm outer point 210 and the first axis 220 is adjusted within the preset first bandwidth range, and the mold of the control arm 200 can be used or changed according to the adjustment amount.

[0087]

Rim 300

[0088] See also Figures 6 - 7 , Figure 6 is a schematic diagram showing the structure of a rim 300 according to an embodiment of the present invention. Figure 7 The embodiment of the present invention provides Figure 6 Cross-sectional view of BB.

[0089] In the present invention, the rim 300 includes a rim mounting surface 310 , and the rim mounting surface 310 is offset relative to the center plane of the rim 300 .

[0090] According to different wheelbases, the relative distance (ET value) between the rim mounting surface 310 and the wheel center 320 of the rim 300 is adjusted within a preset third bandwidth, namely ΔY3 in the figure.

[0091] [Y-direction expansion strategy customized according to the above wheel module 1000]

[0092] Figure 8 It is a flow chart of the expansion method of the wheel-side module provided in an embodiment of the present invention.

[0093] The embodiment of the present invention further provides a method for expanding the wheel edge module provided above. According to the structural design of the wheel edge module 1000 above, a Y-direction expansion strategy can be formulated to implement a general architectural strategy, reduce development risks, and improve development efficiency. The method includes the following steps:

[0094] S101, when the change in wheelbase is within a first threshold range, adjusting the relative distance between the wheel hub bearing and the outer ball pin of the control arm;

[0095] S102, when the change in wheelbase is within the range from the first threshold to the second threshold, adjusting the relative distance between the wheel hub bearing and the outer ball pin of the control arm, and adjusting the relative distance between the outer point of the arm and the first axis;

[0096] S103. When the change in wheelbase exceeds a second threshold, adjust the relative distance between the wheel hub bearing and the outer ball pin of the control arm, adjust the relative distance between the outer point of the adjustment arm and the first axis, and simultaneously adjust the relative distance between the rim mounting surface and the wheel center of the rim.

[0097] In the optional numerical selection, the first threshold is 5 to 10 mm, the second threshold is 50 mm to 70 mm, preferably the first threshold is 5 mm and the second threshold is 60 mm.

[0098] Among them, according to the above methods and structures, complete expansion parameters can be formulated, that is:

[0099] The relative distance between the hub bearing and the outer ball joint of the control arm is adjusted within a preset first bandwidth range;

[0100] The relative distance between the outer point of the arm and the first axis is adjusted within a preset second bandwidth range;

[0101] The relative distance between the rim mounting surface and the wheel center of the rim is adjusted within a preset third bandwidth range.

[0102] Specifically, when the wheel track needs to be adjusted in a small range due to styling differences in vehicles of the same level, and the adjustment amount is 0 to 5 mm on one side at this time, strategy S1 is preferably adopted: that is, change the distance between the hub bearing mounting surface on the steering knuckle and the hard point of the outer ball joint of the control arm. A pre-adjustment amount of △Y1 is reserved on the steering knuckle before machining to ensure generalization, and differentiation can be achieved only through machining, and this strategy does not affect the offset between the wheel center and the hub bearing center.

[0103] When the change in the wheel track of adjacent-level vehicles increases, that is, 5 to 60 mm on one side is within the range of the first threshold to the second threshold, and there will also be a large difference in the tire outer diameter at this time. To avoid the tire movement envelope, strategy S2 is preferably adopted: that is, on the basis of S1, the effective length of the control arm is changed at the same time, the length of the steering tie rod is adjusted accordingly with the control arm, and the outer point of the steering tie rod is finely adjusted according to performance requirements. An adjustment and optimization margin can be reserved on the steering knuckle blank before machining.

[0104] When the change range of the wheel track of cross-level vehicles is even larger, that is, more than 60 mm on one side, then strategy S3 is adopted. Strategy S3 is to adopt different rim ET values on the basis of S2. Considering the layout space of the brake caliper and the manufacturability of the rim, the common ET range is 35 to 55 mm, and a recommended change bandwidth of 10 mm is combined with the reasonable offset between the wheel center and the hub bearing center.

[0105] The above three strategies can cover the one-sided expansion requirements of the Y-direction dimension and have the following effects:

[0106] The above expansion strategy ranking takes into account the impact on the four-wheel alignment parameters, which can reduce the risk of performance development; at the same time, it takes into account the tire selection of different models, protects the suspension movement space in advance, and reduces the risk of tire envelope verification in the later stage; the other expansion strategy ranking takes into account the commonality of the same level of models and the usability of cross-level models of the structure components, and reserves space and performance adjustment margin in the early stage of pre-research to reduce development costs, cycles and performance risks; a single strategy or a combination strategy is given for different expansion bandwidths, with a wide coverage, generally covering three levels of models, and the standardized expansion plan is convenient for internal implementation or formulation of relevant standards within the enterprise, and has strong operability.

[0107] Therefore, through the above design, when the wheelbase of the whole vehicle changes in the Y direction, the parts can be re-molded to reduce the number of parts as much as possible, the connection structure between the adjusted parts and the surrounding connectors remains unchanged, and the number of tooling adjustments and modified parts is very small, which facilitates management and saves costs. [Specific embodiment]

[0109] See also Figure 9 , Figure 9 It is a wheel side module of a Sedan (a type of vehicle) model before the exemplary display expansion of the present invention, Figure 10 is based on Figure 9 The car models in the series are expanded into wheel side modules for SUV models.

[0110] In this specific embodiment, strategy S3 is adopted by utilizing the above-mentioned structural design; that is, when the change in wheelbase exceeds the second threshold, the relative distance between the wheel hub bearing and the outer ball pin of the control arm is adjusted, the relative distance △L2 between the outer point of the adjustment arm and the first axis is adjusted, and the relative distance △L1 between the rim mounting surface and the wheel center of the rim is adjusted.

[0111] Among them, △L1 is adjusted to △L1′, increasing by 10mm; △L2 is adjusted to △L2′ and △L3 is adjusted to △L3′, both increasing by 26.5mm; at the same time, the relative distance between the wheel hub bearing and the outer ball pin of the control arm is adjusted by 6mm; and a total expansion of 42.5mm in the Y direction is achieved in the wheel side module on one side.

[0112] From the above, it can be seen that the wheel module can be expanded in the Y direction according to the adjustable steering knuckle, control arm and rim, fewer parts need to be re-molded, and the connection structure between the adjusted parts and the surrounding connectors can remain unchanged, thereby reducing development risks and costs.

[0113] And according to the structural design of the wheel-side module above, a fixed strategy or strategy combination can be formed in the expansion plan in the Y direction (horizontal). The bandwidth is given for each strategy in combination with the motion gap and performance boundary, which can form internal enterprise specifications or standards and improve the work efficiency in the pre-research stage of the platform architecture.

[0114] On the other hand, an embodiment of the present invention also provides an automobile (not shown in the figure), which includes:
