Detailed Description
It should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", "clockwise", "counterclockwise", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of describing the present invention and simplifying the description, but do not indicate or imply that the referred device or element must have a specific orientation, be constructed in a specific orientation, and be operated.
In the present invention, unless otherwise expressly stated or limited, the terms "disposed," "mounted," "connected," and the like are to be construed broadly, e.g., "fixed" may be fixedly connected, detachably connected, or integrally formed; the connection can be mechanical connection or electrical connection; the connection may be direct or indirect via an intermediate medium, and may be communication between the two elements or an interaction relationship between the two elements. The specific meanings of the above terms in the present invention can be understood according to specific situations by those of ordinary skill in the art.
Checking whether the tire envelope and the clearance between the front side of the wheel arch and the rear side of the wheel arch are more than or equal to 10mm or not, wherein the front side of the tire and the wheel arch is a dimension a and the rear side of the tire and the wheel arch is a dimension c which are both 40mm;
if the gap is more than or equal to 10mm, the front side dimension a of the tire and the wheel arch and the rear side dimension c of the tire and the wheel arch are both 40mm;
if the clearance is less than 10mm, the tire-wheel-arch front side dimension a and the tire-wheel-arch rear side dimension c are the maximum of the front and rear side wheel-opening dimensions corresponding to the tire envelope and the wheel-arch front and rear clearance of 10mm.
Wheel opening dimensions (b and d) were initially determined in the following sequence as described in table one: (1) b4& d4 (2) &d3 or b3& d4 (3) &3 d3 or b2& d4 or b4& d2, b4 means that b is scored 4 points, the corresponding size is 40-50mm, the wheel opening size is preferably the minimum value, and each scheme is required to satisfy the tire envelope and the wheel-arch clearance e of more than or equal to 10mm.
If the clearance e between the wheel arch and the tire enveloping surface can not meet the requirement, namely is more than or equal to 10mm, the size of the wheel arch flanging is reduced, the opening of the wheel arch flanging is opened, or the wheel arch shape is adjusted.
If the tire envelope and the wheel arch gap cannot be adjusted to 10mm all the time by the above method, the next wheel arch size scheme check is performed in sequence.
The wheel rim perception quality indexes mainly comprise a front side dimension a of the tire 2 and the wheel arch 1, an upper side dimension b of the tire 2 and the wheel arch 1, a rear side dimension c of the tire 2 and the wheel arch 1 and a lateral dimension d of the tire 2 and the wheel arch 1.
The front side dimension a of the tire 2 and the wheel arch 1 and the rear side dimension c of the tire 2 and the wheel arch 1 are equal in value and not less than 40mm, and meanwhile the requirement that the clearance e between the tire enveloping surface 5 and the wheel arch 1 is not less than 10mm is met.
The value of the upper side dimension b of the tire 2 and the wheel arch 1 is 40-80mm, the value of the lateral dimension d of the tire 2 and the wheel arch 1 is 5-25mm, meanwhile, the requirement that the clearance e between the wheel arch 1 and the tire enveloping surface 5 is more than or equal to 10mm is ensured, and the smaller value of the upper side dimension b of the tire 2 and the wheel arch 1 and the lateral dimension d of the tire 2 and the wheel arch 1 is preferably selected. The static evaluation tables of the upper side dimension b of the tire 2 and the wheel arch 1 and the lateral dimension d of the tire 2 and the wheel arch 1 are shown in the first table.
As shown in fig. 4, when the gap e between the wheel arch and the tire envelope surface cannot meet the requirement, the wheel arch can be flanged by reducing the wheel arch flanging size f, and the edge-wrapping structure 7 can be referred to.
As shown in fig. 5, when the gap e between the wheel arch and the tire enveloping surface can not meet the requirement, on the premise of ensuring the strength of the wheel arch, a notch 8 can be opened at the wheel arch flanging, and the region with insufficient gap between the wheel arch flanging and the tire enveloping surface 5 can be removed, so as to adjust the size of the wheel arch to meet the target requirement.
As shown in FIG. 6, when the size of the wheel opening can not be adjusted to a reasonable size all the time, if the shape of the wheel arch 1 is adjustable, the shape of the wheel arch 1 can be adjusted to meet the requirement of the gap between the tire envelope 5 and the wheel arch 1, and then the size of the wheel opening is adjusted to meet the target requirement.
