Abstract

The invention discloses a steering axle assembly matched with a composite air suspension. The steering axle assembly comprises a steering trapezoidal mechanism, a hydraulic oil cylinder for driving the steering trapezoidal mechanism, an air bag and a plate spring, wherein one end of the hydraulic oil cylinder is connected to a trapezoidal arm of the steering trapezoidal mechanism, and the other end of the hydraulic oil cylinder is connected to an axle shaft of the steering trapezoidal mechanism. The upper end face of the middle of the axle shaft is higher than the wheel center of the wheel, the plate springs are installed on the two sides of the axle shaft, the two ends of each plate spring are connected to the lower end of the air bag and a vehicle frame respectively, the plate springs are guide arms of the corresponding air bags, and the upper ends of the air bags are installed on the vehicle frame. According to the steering axle assembly matched with the composite air suspension, the hydraulic steering axle and the combined type air suspension are integrated, the transverse thrust rod support is arranged on the axle shaft, the transverse thrust rod is installed on the transverse thrust rod support, the structure is compact, and the layout is reasonable; the axle shaft adopts a negative drop shaft structure, so that the minimum ground clearance of the steering axle is increased.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a steering axle assembly matching a composite air suspension. Background technique [0002] The steering axle refers to the axle that undertakes the steering task. The front axle of a general car is a steering axle, and the front and rear axles of a four-wheel steering car are all steering axles. The steering axle uses the steering knuckle in the axle to deflect the wheels at both ends by a certain angle to realize the steering of the car. In addition to bearing the vertical load of the car, the steering axle also bears the longitudinal force and lateral force and the moments caused by these forces. The steering axle is one of the main load-carrying assemblies of the vehicle, and it is usually designed to match with another load-bearing system—the suspension system. Suspension system is a general term for all force-transmitting connection devices between the frame of a car an...
