Abstract
A hydraulic control mechanism for a four-gear sliding gear comprises a piston shaft, a positioning ring, an end cover, a piston cylinder, piston sleeves, a box body, the four-gear sliding gear, a shifting fork, a pin, a guidance key, a cylinder sleeve, pipe joints, a sealing ring, proximity switches and a support. The controlling shifting fork of the four-gear sliding gear is supported on the cylinder sleeve. The piston shaft in the cylinder sleeve is connected with the shifting fork through the pin. The piston cylinder is designed to be of a step hole structure with two ends big and the middle portion small. The middle portion of the piston shaft is matched with the piston cylinder. The piston sleeves are arranged between the two ends of the piston shaft and the piston cylinder so that movement fit can be achieved. The piston cylinder is provided with the four pipe joints which correspond to cavities formed by the piston cylinder, the piston shaft and the piston sleeves correspondingly. Hydraulic oil enters piston cavity holes through the pipe joints. The piston sleeves and the piston shaft are controlled to be positioned through the pressure change of the hydraulic oil in the four pipe joints, so that the four-gear sliding gear is controlled to be in different engagement positions, and a signal is transmitted when the positioning ring reaches the corresponding proximity switch.
