Problems solved by technology

Both the lifting operation and the braking operation need to use compressed gas, the control system is complicated and the cost is high, and when the lifting axle is lifted, its air chamber is still braking, which wastes compressed gas and reduces the performance and efficiency of the braking system

Abstract

The invention discloses an electrical joint control braking system for a lifting axle of a commercial vehicle. The electrical joint control braking system comprises a lifting control gas circuit and a braking control gas circuit; a bearing airbag is connected with a relay valve for the bearing air bag; the relay valve for the bearing air bag is divided into two branches; one branch is connected with a gas holder for a suspension; the other branch is connected with the gas holder for the suspension through a three-position and five-way electromagnetic valve and a pressure regulating valve in sequence; a lifting airbag is also connected with the gas holder for the suspension through the three-position and five-way electromagnetic valve and the pressure regulating valve in sequence; a braking air chamber is connected with a relay valve for braking; the relay valve for braking is also divided into two branches; one branch is directly connected with a gas holder for driving; the other branch is connected with an upper chamber of a braking foot valve through a two-position and three-way electromagnetic valve; and a switch is separately connected onto the three-position and five-way electromagnetic valve and the two-position and three-way electromagnetic valve. The electrical joint control braking system is reliable and simple in lifting and braking and low in cost; and no braking of the lifting axle in an elevating state, and normal braking of the lifting axle in descending and bearing states are guaranteed.

Description

technical field [0001] The invention relates to the field of control systems for lift axles of commercial vehicles, in particular to an electrical combined control braking system for lift axles of commercial vehicles. Background technique [0002] In recent years, the role of lifting axles in transport vehicles has been more and more widely accepted and applied. When the vehicle is fully loaded, the lifting bridge is lowered to carry the load; when the vehicle is empty or lightly loaded, the lifting bridge can be lifted to reduce the frictional resistance between the tire and the ground, reduce fuel consumption, and reduce tire wear. [0003] Usually, the lift axle of a commercial vehicle is lifted and lowered by controlling the inflation and deflation of the air bag. Both the lifting operation and the braking operation need to use compressed gas, the control system is complicated and the cost is high, and when the lifting axle is lifted, its air chamber is still braking, w...
