Abstract

A high-load retarder with a welding type piston relates to a retarder and aims at solving the problem that the existing high-load retarder is large in speed judgment overflow area and cannot conduct speed judgment gear selection. A second overflow channel is arranged on an upper piston, a plurality of first overflow channels parallel to the second overflow channel are arranged on the lateral wall of the upper piston along a circle, a groove is arranged on the upper end face of a lower piston, a Y-shaped channel is arranged at the center position of the lower piston, and the lower end face of the upper piston and the upper end face of the lower piston are mutually welded. A vertical overflow hole is arranged on the connection face of the upper piston and the lower piston, a sealing cover is connected with the lower end of a sliding oil cylinder in sealing mode, a valve plate overflow hole is arranged on a speed valve plate, a speed valve spring is arranged in the second overflow channel, a transverse oil through hole is arranged on a piston rod at the lower end of each piston, the overflow area of the upper end of the Y-shaped channel is smaller than the overflow area of the vertical overflow hole, and the overflow area of the vertical overflow hole is smaller than the overflow area of the second overflow channel. The high-load retarder is used for railway deceleration.

Description

technical field [0001] The invention relates to a deceleration top, in particular to a welded piston high-load deceleration top. Background technique [0002] With the development requirements of high-speed and heavy-duty railways at home and abroad, the speed-regulating equipment of high-load series deceleration jacks has been widely promoted and applied. The piston is one of the important components of the high-load retarder, which directly determines the braking performance of the high-load retarder. [0003] The Chinese patent number is ZL200420063146.2, and the patent of invention issued on September 28, 2005 discloses a "high-load deceleration top". Although the deceleration top has high body strength, good overall guidance, high critical speed accuracy, The number of cloth tops is small, the occupied line is short, the load performance is high, and the safety performance is good. The piston and the piston rod of the deceleration top have an integrated structure. Alth...
