Description

technical field [0001] The invention relates to the technical field of vehicle engineering, in particular to an automobile leaf spring suspension system integrated with a brake air reservoir, which is mainly suitable for reducing the difficulty of arrangement and improving the versatility. Background technique [0002] The air storage tank of the traditional bus chassis is generally arranged inside the frame, and space for components such as the luggage compartment, fuel tank, urea tank, and air-conditioning condenser must be reserved outside the frame. With the implementation of the National VI emission regulations, the length of the tail treatment of the National VI engines is generally too long, and there are strict requirements on the installation position, which occupies the space inside the frame. In the existing technology, the air storage tank is mostly arranged on the inside of the frame. The air storage tank is limited by the vehicle width, wheelbase, and rear trea...
