Abstract

The utility model discloses a heat dissipation type hub which comprises a hub body. A concave slug hole is formed on the mounting surface of the hub body; a through hole penetrating through the inner and outer parts of the mounting surface is formed on the concave surface of the slug hole; and a drainage flute is formed on the end surface on the outer side of the slug hole. The heat dissipation type hub has the advantages that the heat dispersion and the drainage property of the hub are enhanced, and the aesthetic property is also improved.

Description

The heat radiating type wheel hub

Technical field

The utility model relates to a kind of heat radiating type wheel hub.

Background technology

Wheel hub is wheel rim again, it is the important parts that travel of automobile, bear quite a few load that produces in the vehicle traveling process, aluminium alloy wheel hub is the product after automotive hub experiences very long development, characteristics such as it is fuel-efficient with light weight, rapid heat dissipation, out of roundness are good, attractive in appearance, attracting selecting for use of increasing intermediate car, and its beautiful wheel hub outward appearance can be with giving strong visual impact.Its mode of operation of automotive hub moves in high speed, think the safety that guarantees automobile, the performance of the intensity of wheel hub and heat radiation etc. is had certain requirement, insufficient strength is the important hidden danger of driving safety, heat radiation does not with great difficulty influence the tire internal gas pressure, makes vehicle accident occur.For the automobile of running at high speed, because of phenomenons such as the high temperature of generations such as wheel hub distortion, braking is blown out, brake efficiency reduction of common occurrence.And the indent slug hole 1 on the existing wheel hub attachment face ' deep, see Fig. 1, rainy day easy ponding.

Summary of the invention

For solving because of wheel hub high temperature causes automobile flat tire, the easy problem of ponding, the utility model provides a kind of perfect heat-dissipating, heat radiating type wheel hub that drainage performance is good.

The technical solution of the utility model:

The heat radiating type wheel hub comprises hub body, and the attachment face of described hub body is provided with the slug hole of indent, it is characterized in that: have the through hole that runs through the attachment face inside and outside on the inner concave of described slug hole, have drainage channel on the outside end face of described slug hole.

The tank that begins to rehearse on described slug hole helps the discharge of the ponding on the slug hole, and the thermal diffusivity that has increased wheel hub.

The bottom of slug hole has through hole, increases draining heat radiation and aesthetics.

Advantage of the present utility model: strengthened the heat dispersion and the drainage of wheel hub, and improved aesthetics.

Description of drawings

Fig. 1 is existing wheel hub structure scheme drawing.

Fig. 2 is a structural representation of the present utility model.

Fig. 3 is a lateral plan of the present utility model.

The specific embodiment

With reference to Fig. 2, Fig. 3, the heat radiating type wheel hub comprises hub body 1, and the attachment face of described hub body 1 is provided with the slug hole 2 of indent, have the through hole 3 that runs through the attachment face inside and outside on the inner concave of described slug hole 2, have drainage channel 4 on the outside end face of described slug hole 2.

The tank 4 that begins to rehearse on described slug hole 2 helps the discharge of the ponding on the slug hole 2, and the thermal diffusivity that has increased wheel hub.

The bottom of slug hole 2 has the through hole 3 of diameter 8mm, increases draining heat radiation and aesthetics.

The described content of this specification sheets embodiment only is enumerating the way of realization of utility model design; protection domain of the present utility model should not be regarded as only limiting to the concrete form that embodiment states, protection domain of the present utility model also reach in those skilled in the art according to the utility model design the equivalent technologies means that can expect.

Claims

1. the heat radiating type wheel hub comprises hub body, and the attachment face of described hub body is provided with the slug hole of indent, it is characterized in that: have the through hole that runs through the attachment face inside and outside on the inner concave of described slug hole, have drainage channel on the outside end face of described slug hole.
