The invention provides an anti-snaking shock absorber capable of achieving the frequency-variable stiffness characteristic, hydraulic rubber joints and application. The shock absorber comprises an oil anti-snaking shock absorber, the two ends of the oil anti-snaking shock absorber are rod ends, and the left hydraulic rubber joint and the right hydraulic rubber joint are installed in the rod ends of the two ends of the oil anti-snaking shock absorber correspondingly. Connecting rods are mounted at the core parts of the hydraulic rubber joints, and the connecting rods are fixed with a bogie or a vehicle body end. Each hydraulic rubber joint is cylindrical and comprises an outer metal sleeve and an inner metal sleeve, a hydraulic cavity is formed between the outer metal sleeve and the inner metal sleeve, a main spring is embedded into the hydraulic cavity, a gap between the top of the main spring and an outer flow channel is an upper flow channel, a gap between the bottom of the main spring and the outer flow channel is a lower flow channel, and hydraulic cavities are formed in the left side and the right side of the main spring. The transverse dynamic performance of a motor train unit in the extreme wheel-rail contact state can be improved, the maintenance requirement for the wheel-rail profile shape is lowered, and the purpose of lowering the operation and maintenance cost of a high-speed train is achieved.
