Abstract

Disclosed are a bogie for a railway wagon and a side frame thereof. The side frame is provided with a triangle hole (1), and a lower hole wall of the triangle hole (1) is provided with a mounting surface (2); the mounting surface (2) is provided with a protrusion part (3) which extends upwards and downwards, so that a crossing rod (4) of the bogie is sheathed on the protrusion part (3) through a connecting hole (41) thereof; and a connecting part (31) is provided above the protrusion part (3), and the connecting part (31) is used for connecting a connecting piece (5) for limiting the crossing rod (4). The crossing rod (4) can be directly sheathed on the protrusion part (3) through the connecting hole thereof without penetrating the triangle hole (1) to protrude outwards, so that the length and weight of the crossing rod (4) can be effectively reduced, and the normal position control capability of the crossing rod (4) can be improved. The triangle hole (1) on the side frame can be used reasonably without welding a connecting seat at an outer side of the triangle hole (1) separately, thereby simplifying the structure of the entire side frame. The connection between the protrusion part (3) and the hole wall of the triangle hole (1) is relatively reliable, thereby reducing weak connecting links and avoiding the occurrence of stress concentration.

Abstract

A platform-based container. The platform-based container comprises a bottom frame (1) locked to a container flatcar by means of corner elements (11), and side columns (2) disposed on two sides of the bottom frame (1). The side columns (2) are movably connected to the bottom frame (1), so that the side columns (2) have two switchable working positions. When the side columns (2) are in the first working position, the side columns (2) are fixedly connected to the bottom frame (1), so that the bottom frame (1), with its top surface, and inner side surfaces of the side columns (2) on the two sides of the bottom frame (1) define a goods bearing space. When the side columns (2) are in the second working position, the side columns (2) are folded to be overlapped with the bottom frame (1). By means of the platform-based container, multiple containers can be stacked for transportation and storage conveniently, convenience for transportation and storage of empty containers is improved, and cost is saved.

Abstract

Disclosed is a railway freight car car-coupler buffer comprising a car coupler, a coupler yoke fixedly connected to the car coupler, a traction buffer unit arranged within the coupler yoke, and a compression buffer unit connected to the bottom of the coupler yoke. Also, the traction buffer unit comprises multiple pairs of stacked traction buffer unit bodies; first positioning grooves and first positioning protrusions that fit with each other are provided on the contact surfaces of the traction buffer unit bodies in each pair of traction buffer unit bodies. Because the traction buffer unit is in a compressed state when providing a buffering effect, and the first positioning protrusions on the traction buffer unit bodies are embedded into the first positioning grooves during a compression process, lateral movement cannot be generated among the traction buffer unit bodies, as such, the entire buffer unit can only move in the longitudinal direction. This effectively prevents the buffer unit of the car-coupler buffer from generating a lateral movement while moving in the longitudinal direction, thus effectively preventing the car-coupler buffer from being damaged.

Abstract

A bogie of a railway vehicle includes two groups of wheel sets, adapters (4) arranged on the wheel sets bearings and a side frame (1) on two adapters (4) which are provided at the same side. A first elastic cushion (2) lies between the adapter (4) and the horizontal contact surface of the side frame guide (11). Two second elastic cushions (3, 6) separately lie between the adapter (4) and both sides contact surfaces of the side frame guide (11). The first elastic cushion provides the ideal vertical static flexibility without considering the transverse rigidity at the same time. The second elastic cushion provides larger longitudinal rigidity, and the two elastic cushions provide right lateral rigidity. The invention also includes the railway vehicle using the bogie. The invention enables fully elastic locating and restraint to the wheel sets, and makes the vertical, longitudinal, and transverse rigidity to the optimum. The invention can satisfy the design needs of different performance vehicles.
