Abstract
The invention relates to a braking system for a low-platform trailer, which comprises a single-cavity parking brake air chamber and a single-cavity travelling brake air chamber. An air source air circuit pipe is connected with the single-cavity parking brake air chamber, a control air circuit pipe is connected with the single-cavity travelling brake air chamber, and the air source air circuit pipe and the control air circuit pipe are connected with an air source. When air is supplied to the single-cavity parking brake air chamber by the air source air circuit pipe, parking brake is relieved. When air is supplied to the single-cavity travelling brake air chamber through the control air circuit pipe, traveling brake is operated, and at most one of the air source air circuit pipe and the control air circuit pipe is aerated. The single-cavity parking brake air chamber and the single-cavity travelling brake air chamber are used separately, so that mounting space of a brake is saved, and the braking system is applicable to low transport of low-platform trailers and convenient in mounting and operation. The mounting space of the brake is saved to a great extent as compared with that of a traditional double-cavity brake air chamber by using the single-cavity parking brake air chamber, the requirements of the low-platform trailers on low transport height can be met, and low and smooth transport of large articles is guaranteed.
