Embodiment Construction

[0020] Such as Figure 1-Figure 5 As shown, a composite elbow-type liquid-pneumatic suspension device includes a torsion bar spring 1, a damping element 2, a connecting arm 3, a balance elbow body 4, a connecting tooth sleeve 5, a rolling bearing 6, a balance toggle shaft 7, and a connecting arm. Rod 9, main piston 11, charging valve 14, floating piston 15 and road wheel axle 18. The gas spring of the composite elbow oil-gas suspension device is arranged inside the balance elbow body, and two cylinder barrels are arranged inside the balance elbow body 4, one is a power cylinder for placing the main piston 11 with a connecting rod 9, and the inside is filled with The oil forms a liquid chamber 13, and the other is a cylinder for storing nitrogen gas. The gas and oil are separated by a floating piston 15. The main piston 11 is hinged to the connecting rod 9. The other end of the connecting rod 9 is fixed at an eccentric position outside the balance toggle shaft 7. , which is th...

Abstract

The invention relates to a composite elbow-type liquid-pneumatic suspension device. By providing a composite new suspension device with two kinds of elastic elements for heavy-duty tracked armored vehicles, and arranging the center of rotation of the connecting rod outside the balance toggle shaft, and assembling a coaxial blade damping element with temperature control function, The problems of unreasonable vibration cycle, suspension rigidity and dynamic specific potential energy in the prior art are solved. Including torsion bar spring (1), damping element (2), connecting arm (3), balance elbow body (4), connecting tooth sleeve (5), rolling bearing (6), balance toggle shaft (7), connecting rod (9), the main piston (11), the inflation valve (14), the floating piston (15) and the road wheel axle (18), can make the vehicle have a larger dynamic range, and further improve the off-road passability and riding comfort of the whole vehicle .

Description

Technical field: [0001] The invention relates to a heavy-duty crawler vehicle suspension device, in particular to a composite elbow-in-type liquid-pneumatic suspension device. Background technique: [0002] At present, my country's heavy-duty tracked vehicle suspension system has two types: torsion bar independent suspension system and fixed cylinder oil-gas spring independent suspension system. The torsion bar independent suspension system consists of blade hydraulic shock absorber, balance elbow, torsion bar, The disadvantage is that the suspension system is too rigid, and it is not suitable for road conditions when it is fixed; the fixed cylinder type oil-pneumatic spring type independent suspension system is composed of oil-pneumatic springs, balance elbows, and buffers, and its disadvantage is that the suspension rigidity is too high. Soft, prone to motion sickness, the balance elbow is a purely mechanical component, which acts as a guiding element, and the oil-pneumatic ...
