Embodiment 1

[0034] Please refer to Figure 1 to Figure 4 , the present embodiment discloses a heavy-duty vehicle 10 with full oil and gas spring suspension, including a vehicle frame 100, a front axle, a front axle oil cylinder 300, a support arm 400, a rear axle 500 and a rear axle oil cylinder 600, and the vehicle frame 100 includes a longitudinal beam 110 and the ring beam 120 fixedly connected with the longitudinal beam 110. The frame 100 is connected to the axle through the oil cylinder, including: the cylinder barrel of the rear axle oil cylinder 600 is rotatably connected to the longitudinal beam 110, the rod of the rear axle oil cylinder 600 is rotatably connected to the rear axle 500; the front axle oil cylinder 300 The cylinder barrel is rotatably connected with the longitudinal beam 110, such as 2 and Figure 4 As shown, the support arm 400 is provided with a first end 410, a second end 420 and a third end 430, the first end 410 is connected with the front wheel hub 210 of the...

Embodiment 2

[0053] Please refer to Figure 5 with Image 6 , the present embodiment discloses a heavy-duty rigid wide-body dump truck 20 with full oil-gas spring suspension, including the heavy-duty vehicle 10 with full oil-gas spring suspension in Embodiment 1, so as to be applied in the field of dump trucks.

[0054] Specifically, the full oil-gas spring suspension heavy-duty rigid wide-body dump truck 20 also includes a driver's cab 21, a compartment 22, and a lifting cylinder 23. The driver's cab 21 is installed on the front part of the vehicle frame 100, and the rear part of the compartment 22 is pinned to the vehicle frame 100. One end of the lifting cylinder 23 is pinned to the vehicle frame 100 , and the other end is pinned to the front portion of the compartment 22 .

Abstract

The invention discloses a full hydro-pneumatic spring suspension heavy vehicle, relates to the technical field of vehicle hydro-pneumatic suspensions, and solves the technical problems that a leaf spring type suspension in the prior art has frequent fracture fault defects and the bearing and damping capacities are not matched with a large load. A cylinder barrel of the front axle oil-gas cylinder is rotatably connected with the longitudinal beam, the corbel is provided with a first end part, a second end part and a third end part, the first end part is connected with a front wheel hub of the front axle and a rod part of the front axle oil-gas cylinder, the second end part is rotatably connected with the front part of the longitudinal beam, and the third end part is rotatably connected with the ring beam; a cylinder barrel of the rear axle oil-gas cylinder is rotatably connected with the longitudinal beam, and a rod portion of the rear axle oil-gas cylinder is rotatably connected with the rear axle. According to the hydro-pneumatic suspension system formed by the hydro-pneumatic cylinders and related connection, force and torque borne by the wheels are transmitted to a frame and a vehicle body, vibration and impact transmitted by the road surface are absorbed and relieved, meanwhile, the hydro-pneumatic suspension system plays the role of springs and shock absorbers, and traditional springs and plate springs are omitted.

Description

technical field [0001] The invention relates to the technical field of vehicle oil-pneumatic suspension, in particular to a heavy-duty vehicle with full oil-pneumatic spring suspension and a rigid wide-body dump truck. Background technique [0002] Coal is the main energy source and an important industrial raw material. There are off-highway mining wide-body dump trucks on the market for earthwork stripping, coal transportation, and slag discharge in open-pit coal mines. The main load is 60t, and the leaf spring suspension is used. and riveted frame structure. [0003] The leaf spring suspension is adopted. On the one hand, multi-leaf leaf springs are superimposed to provide load-carrying and shock-absorbing functions for the vehicle. However, with the continuous increase of the load-bearing tonnage and the deterioration of the transportation road conditions, the leaf springs have the defect of frequent fracture and failure, resulting in Efficiency is reduced; on the other ...
