Document Type and Number:
WIPO Patent Application WO/2016/106919
Kind Code:
A1
Abstract:
A device for hydraulically demounting a tire of a heavy duty vehicle consists of a tire (6) and a rim (8). A plurality of oil cylinder installation holes (5) is uniformly distributed on the periphery of an end surface of an integrated blocking seat ring (4). A hydraulic oil cylinder (1) is disposed on the upper portion of the oil cylinder installation holes (5). The positions of the oil cylinder installation hole (5) are corresponding to the position of the tire bell (7) of the tire. The integrated blocking seat ring (4) is disposed on one surface of the rim (8) 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) inserted into the oil cylinder installation hole (5) is connected to a T-type cylindrical pushing plate (3). The T-type cylindrical pushing plate (3) is tightly close to the tire bell (7). Each oil cylinder installation hole (5) is provided with a dust preventing cover (9). The device has the advantages that demounting power is strong, demounting operations are safe, the service life of the rim is long, and demounting and repair costs are reduced.
