The invention discloses a braking system of a semi-trailer with a control steering axle, comprising: a braking system and a control system of a steering axle; the braking system includes a service brake air tank, and the control system of a steering axle includes: Pressure reducing valve, follow-up steering load distribution valve, solenoid valve, follow-up steering air reservoir, follow-up steering lock cylinder and follow-up steering centering cylinder; the pressure reducing valve is connected with the service brake air The dynamic steering load distribution valve is connected, the follow-up steering load distribution valve is connected with the follow-up steering air storage tank, and the follow-up steering air storage tank is connected with the follow-up steering centering oil cylinder; the pressure reducing valve is connected with the solenoid valve, and the solenoid valve is connected with the follow-up steering lock The stop cylinder is connected. The invention integrates the control system of the steering axle of the semi-trailer into the braking system, so that the control system of the steering axle and the braking system share a set of pipelines, thereby reducing the cost of vehicle manufacturing.
Description
technical field [0001] The invention relates to the technical field of service braking, in particular to a semi-trailer braking system with follow-up steering axle control. Background technique [0002] At this stage, most of the follow-up steering axles are controlled by full hydraulic or electronically controlled hydraulic methods, and there are no hydraulic pipelines on ordinary semi-trailers; therefore, it is necessary to add a complete set of hydraulic pipelines to the semi-trailer to control The steering of the dynamic steering axle greatly increases the cost of the vehicle. Contents of the invention [0003] Aiming at the deficiencies in the above problems, the present invention provides a semi-trailer braking system with follow-up steering axle control. [0004] The invention discloses a follow-up steering axle control system, comprising: a pressure reducing valve, a follow-up steering load distribution valve, a solenoid valve, a follow-up steering air storage tan...
