Abstract
The utility model discloses a steel rim spoke of a heavy truck, and the steel rim spoke comprises a spoke plate and air holes which are uniformly distributed on an arc part of the spoke plate in the circumferential direction, wherein one side of each air hole is provided with a ventilation port, the ventilation ports face towards the rotation direction of the spoke, each ventilation port is a drop pit which is sunken from inside to outside of the arc part, and arc edges on two sides of the drop pit are respectively transitioned in a smooth curve way to the arc edges of the air holes. The steel rim spoke has beneficial effects that after the air holes are punched on the arc part, the ventilation ports are squeezed by a punching machine on one side of an air inlet passage of each air hole, the ventilation port faces towards the rotation direction of the spoke, so that the airflow when tires rotate successfully enters the spoke along the drop pit and the air holes, the ventilation quantity is increased, the heat radiation performance is improved, the safety and reliability of the spoke are improved, and the service life of the car steel rim spoke 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; Pit, the both sides circular arc limit of pit and the circular arc limit smooth curve transition in wind hole of described vent for caving in laterally from the inboard of circular arc portion.
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; The pit of described vent 3 for caving in laterally from the inboard of circular arc portion forms convexity 4, the circular arc limit, both sides of pit and the circular arc limit smooth curve transition in wind hole 2 outside the lateral of corresponding circular arc portion; 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.
Claims (2)
1. 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 described vent is pit, the circular arc limit, both sides of pit and the circular arc limit smooth curve transition in wind hole of caving in laterally from the inboard of circular arc portion.
2. autotruck steel ring spoke according to claim 1 is characterized in that: described pit extreme depth is 1～3 ㎜.
