The invention provides an all-terrain vehicle which comprises a vehicle frame, a power system, a transmission system, a walking assembly and a cooling system, the cooling system comprises a cooling kettle, the cooling kettle comprises a kettle body and a pressure cover connected to the kettle body, and the pressure cover has a closed state enabling the kettle body to be closed and a communication state enabling the kettle body to be communicated with air. When the pressure in the kettle body is larger than the first critical pressure and smaller than the second critical pressure, the pressure cover is in a closed state, when the pressure in the kettle body is smaller than the first critical pressure or larger than the second critical pressure, the pressure cover is in a communicated state, and the first critical pressure is smaller than the second critical pressure. By adopting the closed cooling kettle, the cooling kettle can be ensured to be in a closed state in most cases, the scattering of the cooling liquid is reduced, and the operation stability of the cooling system is improved. And meanwhile, the closed cooling kettle can be communicated with the atmosphere under extreme conditions, so that the safety of a cooling system is ensured.
本发明提供了一种全地形车,该全地形车包括车架、动力系统、传动系统、行走组件和冷却系统,冷却系统包括冷却水壶,冷却水壶包括壶体和连接至壶体的压力盖,压力盖包括使壶体封闭的封闭状态和使壶体与空气连通的连通状态,当壶体内的压力大于第一临界压力且小于第二临界压力时压力盖处于封闭状态,当壶体内的压力小于第一临界压力或大于第二临界压力时压力盖处于连通状态,第一临界压力小于第二临界压力。本发明通过采用封闭式的冷却水壶,能够保证在绝大部分情况下冷却水壶处于封闭状态,减少冷却液的散佚,提高冷却系统的运行稳定性。同时该封闭式的冷却水壶也能在极端情况下与大气连通,保证冷却系统的安全性。
