Problems solved by technology

[0003] The purpose of the present invention is to overcome the deficiencies of the above-mentioned prior art, and provide a rear suspension system of a wide-body dump truck with limit and fare adjustment; it mainly solves the poor ride comfort of the existing oil-air suspension system, the large tilt of the vehicle frame when lifting, and the oil and gas suspension system. The cylinder is easy to wear and other problems

Embodiment 1

[0014] Example 1, see figure 1 , 2 , 3, 4, select the appropriate suspension cylinder 1, accumulator 2, first damper 3 and second damper 4 according to design requirements; suspension cylinder 1 is composed of sealing assembly 1-1, cylinder head 1-2, piston rod 1-3. Composed of cylinder barrel 1-4, the sealing assembly 1-1 is installed on the cylinder head 1-2, the cylinder head 1-2 and the cylinder barrel 1-4 are fixed together by bolts, and the piston rod 1-3 passes through The sealing assembly 1-1 and the cylinder head 1-2 form a suspended cylinder 1; three groups of evenly distributed damping holes are opened on the piston rod 1-3, and three groups of evenly distributed damping holes are opened on the top of the cylinder 1-4 hole; the damping of the first damper 3 is c, and the damping of the second damper 4 is 5c; install 4 suspension cylinders 1 between the frame and the axle, and install 2 accumulators 2 and 2 first dampers 3. One second damper 4 is fixed on the frame...

Abstract

The invention discloses a wide-body dump truck suspension system with limiting and carfare adjustment. The wide-body dump truck suspension system with limiting and carfare adjustment is characterizedin that suspended cylinders are mounted between axles and a frame; the suspended cylinders on a same side of a vehicle are connected through pipelines, and first dampers and energy accumulators are connected with the suspended cylinders on the same side of the vehicle to play a balance role; the energy accumulators on the left and right sides are connected with the second dampers in the middle ofthe frame through pipelines, the damping of the dampers is larger, and carfare adjustment action is achieved; and the suspended cylinders are composed of sealing assembly pieces, cylinder covers, piston rods and cylinder barrels, wherein three rows of damping holes are separately formed in the piston rods and the cylinder barrels, so that the suspended cylinders own have a limiting action, meanwhile, lateral force can be removed, and eccentric phenomenon is prevented from generating.

Description

Technical field: [0001] The invention relates to the technical field of off-highway wide-body dump trucks, in particular to a rear suspension system for wide-body dump trucks with position limiting and fare adjustment. technical background: [0002] At present, the rear suspension system of wide-body dump trucks generally adopts leaf spring structure, and some manufacturers have begun to try oil-air suspension structure. The suspension cylinders on the same side of the frame are connected by pipelines, and the suspension cylinders on both sides of the frame are not connected; the suspension cylinders are used directly The existing oil-gas separation suspension cylinder relies on the rigid support between the axle and the frame to limit the position; this method has the following disadvantages: 1. When compressing, it relies on the rigid limit and the ride comfort is poor; 2. There is only One oil port, the lateral force is generated when the oil moves, causing the suspension...
