Problems solved by technology

[0003] The present invention solves the problems in the prior art due to improper selection of split piston welding methods, inaccurate selection of welding positions, and false welding, which lead to cracks or even fractures at the welding position of the piston head of the high-load deceleration jack during use, resulting in deceleration. The top sliding cylinder is stuck in the shell, losing the function of the deceleration jack, which brings safety hazards to the vehicle's sliding and marshalling operation, and then provides an integrated reinforced high-load deceleration jack

[0009] Specific implementation mode three: combination figure 1 and image 3 Describe this embodiment, the integrated reinforced high-load deceleration jack described in this embodiment, the distance from the top of the piston 13 to the bottom of the third round hole 13-1 is L, the value of L is 5mm, the top of the piston 13 The distance to the bottom of the fourth circular hole 13-2 is H, and the value of H is 21mm. The distance from the top of the piston 13 to the bottom of the fifth circular hole 13-3 is D, and the value of D is 28mm. Others are the same as the specific embodiment. same.

[0010] working principle

[0011] below the critical speed

[0012] When the rolling speed of the vehicle is lower than the critical speed set by the high-load deceleration top, the speed at which the sliding cylinder is pressed down by the wheel is relatively low, the flow generated by the upper chamber is small, and the hydraulic pressure on the speed valve plate 4 is not enough to o...

Abstract

The invention relates to a retarder, in particular to an integrally reinforced type high-load retarder. The integrally reinforced type high-load retarder aims to solve the problems that in the prior art, as a welding method of a split piston is selected improperly, the welding position is selected inaccurately, and the insufficient soldering exists, the welding position of several piston heads cracks or even raptures when a high-load retarder is used, a sliding oil cylinder of the retarder is clamped in a shell, the functions of the retarder are lost, and potential safety hazards are generated in the humping and marshalling operation of a vehicle. The integrally reinforced type high-load retarder comprises a shell combined assembly, a sliding oil cylinder, a speed valve seat, a speed valve plate, a speed valve spring, a return valve plate, a pressure valve rod, a sealing cover, a sealing ring, a pressure valve spring, a spring seat, a pin shaft and a stop base. The integrally reinforced type high-load retarder further comprises an integrated valve seat and a piston which are cylinders. The integrally reinforced type high-load retarder is used in the field of production of retarders.

Description

technical field [0001] The invention relates to a deceleration jack, in particular to an integrated reinforced high-load deceleration jack. Background technique [0002] The speed reducer is an important component of the automatic speed control system of the railway marshalling. It is a speed control device that automatically controls the rolling speed of the railway vehicles without external energy. The birth of high-load deceleration jacks better meets the development needs of high-speed and heavy-duty railways in my country. The high-load deceleration jack has the characteristics of strong braking capacity, good load-carrying performance, precise critical speed and good guiding heat dissipation, and has achieved good results in actual use. Due to the higher requirements on the production technology level of the high-load deceleration jack and the stricter requirements on the control of the testing process, the processing difficulty becomes greater and the process cost in...
