A kind of air spring and vehicle

Abstract

The invention provides an air spring and a vehicle. The vehicle includes a frame and an air spring supported on the underside of the frame. The air spring includes an auxiliary air chamber and an air bag installed on the auxiliary air chamber. There is a communication channel, the airbag is connected with an air supply device, the auxiliary air chamber is connected with the atmosphere, and the auxiliary air chamber is provided with an opening and closing device at the position of the communication channel. The opening and closing device includes at least one valve hingedly connected to the auxiliary air chamber. The air chamber is also provided with a sealing edge that is sealed with the air valve when the air valve is in the closed state at the communication channel, and there is also an elastic action on the air valve between the auxiliary air chamber and the air valve to make the air valve rotate toward the closed state and make it The elastic member that keeps the valve in the closed state. When the valve is kept in the closed state, the valve is in sealing fit with the corresponding sealing rim, or the valve is in sealing fit with the corresponding sealing rim and the edge of the adjacent valve so as to seal the communication channel. Blocking.

Description

technical field [0001] The present invention relates to the technical field of vehicle suspension, in particular to an air spring and a vehicle. Background technique [0002] The air spring is filled with compressed gas in an airtight container, and uses the compressibility of the gas to achieve elastic support. In order to improve the support performance of the existing vehicle suspension system and improve the driving experience of the occupants in the vehicle, a variable stiffness air spring is developed. spring. [0003] The Chinese invention patent with the authorization announcement number CN105221646B and the authorization announcement date of 2017.08.04 discloses an air spring and a vehicle using the air spring. The air spring includes an air bag, an auxiliary air chamber, a bearing seat and a support seat for bearing the impact force. A communication channel for air flow is arranged between the auxiliary air chamber and the air bag, and an opening and closing devic...

Problems solved by technology

[0005] The purpose of the present invention is to provide an air spring to solve the problem that when the vehicle passes through bumps on the road such as speed bumps, the rigidity of the existing air spring increases due to compression, and the whole vehicle jumps seriously during the passing process and the comfort is poor.

The purpose of the present invention is also to provide a vehicle to solve the problem that when the vehicle passes through bumps on the road surface such as speed bumps, the rigidity of the existing air spring increases due to the compression, the whole vehicle jumps seriously during the passing process, and the problem of poor comfort
