Rear suspension system of mining dump vehicle

Abstract

The invention discloses a rear suspension system of a mining dump vehicle. The rear suspension system of the mining dump vehicle is characterized by comprising a frame (1), a front support (3), a medium axle (4), a hydro-pneumatic suspension cylinder (5), a balance beam (7), a balance shaft (8), a rear axle (9), distance rods (10) and a rear support (11). The front support (3) is connected with the frame (1). The medium axle (4) and the front support (3) are in rigid connection. The medium axle (4) and the frame (1) are connected through the second distance rod (12). The rear support (11) is connected with the frame (1). The rear axle (9) and the rear support (11) are in rigid connection. The rear axle (9) and the frame (1) are connected through the first distance rod (10). The balance shaft (8) and the frame (1) are in rigid connection. The hydro-pneumatic suspension cylinder (5) and the balance shaft (8) are connected through the balance beam (7). The medium axle (4) and the rear axle (9) are connected with the hydro-pneumatic suspension cylinder (5) respectively. The rear suspension system can improve bearing capacity of the vehicle, reduces the failure rate of a rear suspension, and solves the balance problem of arranging a plurality of hydro-pneumatic springs among the multiple axles.

Description

Technical field: [0001] The invention relates to the technical field of mine vehicles, in particular to a rear suspension system of a mine dump truck, especially suitable for 6×4 mine dump trucks. Background technique: [0002] At present, the rear suspension of the existing 6×4 mining dump trucks generally adopts the leaf spring structure. Due to the limitation of the bearing capacity of the leaf spring, its tonnage is generally controlled at about 60 tons, and the failure rate of the leaf spring is relatively high; 4×2 mine The rear suspension of a dump truck adopts an oil-pneumatic spring structure, and its carrying capacity has been greatly improved (currently the maximum tonnage has reached four to five hundred tons), and the failure rate has also been greatly reduced, but the cost of the rear axle and tires is high, resulting in 4×2 The cost of a mining dump truck is much higher than that of a 6×4 mining dump truck of the same tonnage. [0003] At present, some 6×4 mi...
