The invention discloses a wheel unit and a vehicle. According to the method, a rim (1) and a spoke (2) are included, the rim (1) and the spoke (2) are connected in a welded mode, the top face of the rim (1) makes contact with a tire bead and a flap respectively, and composite heat insulation coatings (3) are arranged between the top face of the rim (1) and the tire bead and between the top face of the rim (1) and the flap respectively; the composite heat insulation coating (3) comprises a bonding layer (4) sprayed on the top face of the rim (1) and a heat insulation layer (5) sprayed on the bonding layer. The composite heat insulation coating (3) is sprayed on the rim (1), braking heat can be effectively prevented from being transmitted to a tire through the rim (1), the tire burst risk caused by overheat aging of the tire can be avoided, and the service life of the tire is prolonged. And a spraying device does not need to be used for cooling the tire, so that serious pollution to the road environment is avoided, and the driving safety problem caused under the cold condition in winter is avoided.

    本发明公开一种车轮单元和车辆。该方法包括:轮辋(1)和轮辐(2),所述轮辋(1)和轮辐(2)通过焊接连接,轮辋(1)顶面分别与轮胎胎圈、垫带接触,轮辋(1)顶面和轮胎胎圈之间、轮辋(1)顶面和垫带之间均设置有复合隔热涂层(3);复合隔热涂层(3)包括:喷涂于轮辋(1)顶面的粘结层(4)和喷涂于粘结层之上的隔热层(5)。本发明的轮辋(1)通过喷涂复合隔热涂层(3),能有效的阻止制动热量通过轮辋(1)传递给轮胎,可避免因轮胎过热老化而导致的爆胎风险,提高了轮胎的使用寿命。并且本发明不再需要使用喷淋装置对轮胎进行降温,因此避免了对道路环境造成严重污染,以及在冬季寒冷情况下造成行车安全的问题。
