Description
Technical field
The utility model relates to a kind of wheel nut lid more particularly to a kind of location at spherical surface wheel nut protecting covers.
Background technique
The wheel bearing of light commercial vehicle generallys use location at spherical surface mode and is assembled at present, with spherical surface wheel nut into
Row is confined.Under normal conditions, wheel bolt exposes nut 3-5mm or even longer, and on the one hand unsightly, another aspect nut is torn open
After unloading several times, nuts and bolt gets rusty easily in the case where exposing to the weather drenches with rain the routine works environment such as water splashes, and brings to detachable maintaining
Inconvenience also influences the service life of wheel bolt and nut.Design a kind of location at spherical surface wheel nut protecting cover to wheel nut and
Bolt is protected.Patent publication No: 204387062 U of CN, patent disclosure day: on 06 10th, 2015, patent name " one
Kind of the wheel nut lid with waterproof rib ", a kind of wheel nut lid with waterproof rib, including lid and its it is internal open up in six sides
Chamber, interior six side's chambers surround hexagonal structure by its six side walls, and the middle part of the side wall is axial along interior six sides chamber
It is provided with clamping muscle, nearly lid open side is fixedly connected with waterproof rib on the side wall, and muscle is vertical connects for the waterproof rib and clamping
It connects；The wheel nut lid further includes wheel nut washer snap ring, and the top of the wheel nut washer snap ring and lid are open
The bottom surface of side is fixedly connected, and wheel nut washer snap ring and nut collar insertion cooperate.The design improves wheel nut lid
Clamping force and the waterproofness for optimizing wheel nut lid.But nut collar passes through the interference of nut collar snap ring in above technical scheme
Cooperation is fixed, and can not play snap action completely, in (or in other bad working environments) vehicle high-speed operation, nut cap
It is easy to fall off.Especially because clamping, muscle is vertical with Fang Shui Zhu to be connect, and when the height of projection for clamping muscle is higher than Fang Shui Zhu, is clamped
Muscle has clamping action, but the waterproof action of Fang Shui Zhu reduces, when the height of projection for clamping muscle is lower than Fang Shui Zhu, Fang Shui Zhu's
Waterproof action reinforce, but clamp muscle do not have clamping action then, clamp muscle height of projection it is equal with Fang Shui Zhu when, clamp muscle
The waterproof action of clamping action and anti-water Zhu are relatively preferable, but axially parallel with nut cap due to clamping muscle, when nut cap set
After on nut, it can alter because clamping the axially directed and radial shape of muscle at gap is generated between waterproof rib and nut, lead to water
Into in nut cap.And when hub for vehicle wheel is locked using location at spherical surface wheel nut, due to location at spherical surface wheel nut
Cylinder is divided into hexahedron section and spherical surface section two parts, and without installing nut collar, therefore above technical scheme more seems uncomfortable
With.
Summary of the invention
The purpose of the utility model is to overcome waterproof of the existing technology and clamping ability are poor, and it is fixed to be unable to satisfy spherical surface
The waterproof of position wheel nut and the shortcomings and deficiencies for clamping requirement, provide a kind of location at spherical surface nut protecting cover.Its clamping force is stronger,
It is not easily to fall off, good waterproof performance, and structure is simple, higher integral strength, and production cost is low.
In order to achieve the above object, the technical solution of the utility model is as follows:
A kind of location at spherical surface wheel nut protecting cover, including lid, the inside of lid offer interior six side's chambers, and described is interior
