Device for hydraulically demounting tire of heavy duty vehicle

Abstract

The present invention provides a device for hydraulically demounting a tire of a heavy duty vehicle consisting of a tire (6) and a rim (8), wherein, a plurality of oil cylinder installation holes (5) are evenly distributed on the periphery of an end face of an integrated side seat ring (4), a hydraulic oil cylinder (1) is disposed above each of the oil cylinder installation holes (5), the position of each of the oil cylinder installation holes (5) corresponds to the position of bead heel of the tire (7), the integrated side seat ring (4) is disposed on a face of the rim (8) that is in contact with the tire, the hydraulic oil cylinder (1) is provided with an oil cylinder ejecting rod (2), one end of the oil cylinder ejecting rod (2) that is inserted into one of the oil cylinder installation holes (5) is connected to a T-type cylindrical pushing plate (3), and the T-type cylindrical pushing plate (3) is located closely to the bead heel of the tire (7), and each of the oil cylinder installation holes (5) is provided with a dust preventing cover (9). This device has the advantages such as strong demounting power, safe demounting operation, long service life of the rim, and reduced demounting and repair costs.
