Abstract
The utility model discloses a steel rim spoke for a lorry. The steel rim spoke comprises a spoke plate and air holes, the air holes are circumferentially and uniformly distributed on an arc of the spoke plate, an air vent is arranged on one side of each air hole, faces the rotation direction of the spoke and is a pit sinking from the outer side of the arc to the inner side of the arc, and arc edges on two sides of each pit and arc edges of the air holes are in transition by smooth curves. The steel rim spoke has the advantages that the air vent facing the rotation direction of the spoke is extruded on one side of an air inlet channel of each air hole on a punching machine after the air holes are punched on the arc, airflow in rotation of a wheel smoothly enters the spoke along the pits and the air holes, the ventilation quantity is increased, the heat dissipation performance is improved, safety and reliability of the spoke are further improved, and the service life of the steel rim spoke for the lorry is prolonged.
Description
Technical field
The utility model relates to a kind of automobile spoke, particularly a kind of autotruck steel ring spoke.
Background technology
Be evenly distributed with a plurality of waist shapes or circular breather port in the prior art on the spoke of motor tire steel ring, so that the distributing of the heat on tire and the wheel rim, but be contained in when moving on the wheel when spoke; The formed angle of air-flow and wind hole is bordering on 90 degree; So air-flow is not to get into spoke inside very smoothly, thereby cause the spoke thermal diffusivity bad, can cause spoke to heat up behind the long-play; Spoke strength degradation consequently, serious also possibly cause traffic accident and generation.
Summary of the invention
The purpose of the utility model is to overcome weak point of the prior art, and a kind of Automobile steel ring spoke that strengthens performance of ventilating, improves service life and safe reliability is provided.
To achieve these goals; The technical scheme of the utility model is: a kind of autotruck steel ring spoke; Comprise disc, the circumferential well-distributed wind of disc circular arc portion hole, it is characterized in that described wind hole one side is provided with vent; Described vent is towards the hand of rotation of spoke, and vent is the pit from the inboard depression in lateral of circular arc portion; The circular arc limit, both sides of pit and the circular arc limit smooth curve transition in wind hole.
Further, described pit extreme depth is 1～3 ㎜.
The beneficial effect of the utility model is: behind the circular arc portion stamping-out wind hole; On punch press once more in the wind hole one side extrude the vent of dimple-shaped, vent is towards the hand of rotation of spoke, the air-flow when making wheel revolutions gets into spoke inside along the wind hole smoothly smoothly along vent; Increase ventilation volume; Improve heat dispersion, and then improved the safe reliability of spoke, prolonged the service life of Automobile steel ring spoke.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the lateral plan of the utility model.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described further.
As depicted in figs. 1 and 2; The autotruck steel ring spoke of the utility model comprises disc 1, the circumferential well-distributed wind of disc 1 circular arc portion hole 2, and described wind hole 2 one sides are provided with vent 3; Described vent 3 is towards the hand of rotation of spoke; Vent 3 is the inboard pit that caves in from the lateral of circular arc portion, and the inboard of corresponding circular arc portion inwardly forms convexity 4, the circular arc limit, both sides of pit and the circular arc limit smooth curve transition in wind hole 2; Described pit extreme depth is 1～3 ㎜.
The technical scheme of the utility model is not limited to the restriction of above-mentioned specific embodiment, and every technology distortion of making according to the technical scheme of the utility model all falls within the protection domain of the utility model.
