Embodiment Construction

[0019] The main part of the tension / compression damper represented in Figures 1 to 3 comprises a housing 1 and a piston member 3 which is movable and guided along an axis 2 inside the housing. The housing 1 essentially consists of an inner section 4 , an outer section 5 and a seal 6 . The inner section 4 in turn comprises a cylindrical part 7 and a connecting part 8 . The outer section 5 of the housing 1 comprises a cylindrical portion 9 and a partition 10 . The seal 6 is housed in one end of the cylindrical portion 9 of the outer section 5 of the housing 1 .

[0020] The piston member 3 comprises a head 11 and a rod 12 . A cylindrical cavity 13 is provided in the rod 12 . The cavity is closed at the end with a damper plate 14 .

[0021] The piston member 3 is guided to move along the axis 2 within the housing 1 . To this end, the head 11 of the piston component is guided in a sealing manner on the inner wall 15 of the cylindrical part 9 of the outer section 5 of the hous...

Abstract

The invention relates to a traction / compression buffer for coupling devices on rail and wheel-mounted vehicles comprises a housing (1) and a piston element (3), which projects out of said housing on one side and which can be moved out of a zero position in two directions against the resistance of a spring device and a damping device. A hydraulic damping device is provided for damping the return movement of the piston element (3) out of the position in which it is drawn out of the housing (1), in the direction of the zero position. Said hydraulic damping device comprises a ring-shaped hydraulic working chamber (32) that surrounds the piston element (3) and that is connected to an overflow chamber (29) by at least one overflow channel (31).

Description

technical field [0001] The invention relates to a tension / compression buffer for a trailer on a rail vehicle and a wheeled vehicle, comprising a housing and a piston member protruding from the housing on one side, the piston member can overcome the resistance of a spring device and a damping device Move from zero in both directions. Background technique [0002] Double-acting tension / compression dampers of the above-mentioned type damp both backlashes acting in the pressurizing direction and starting shocks acting in the tractive direction; they are used in particular in various vehicles, and preferably in rail vehicles. In this case, the spring-in movement of the strongly damped piston element and the ejection movement of the weakly damped piston element are strived for during a recoil, and the pull-out movement of the weakly damped piston element and the return movement of the strongly damped piston element are aimed for during a starting impact. In known tension / compress...
