Embodiment Construction

[0016] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0017] Such as figure 1 The suspension damping system of the road-rail dual-purpose vehicle shown includes two damping airbags 51, a lifting airbag 52 and an axle lift valve 53, and the upper ends of the two damping airbags 51 are connected to the frame of the road-railway container semi-trailer. The beam assembly is connected, the lower ends of the two damping airbags 51 are connected with the axle 54, the upper end of the lifting airbag 52 is connected with the center beam assembly, the lower end of the lifting airbag 52 is connected with the axle 54 through the lifting lever 55, and the axle lift valve 53 is installed in the middle. On the beam assembly, the axle 54 of the tire 50 is connected with the middle beam assembly through the tire lever 56 and the bracket 57 in turn. In this embodiment, the center beam assembly includes t...

Abstract

The invention discloses a suspension vibration damping system of a highway-railway convertible car. The suspension vibration damping system of the highway-railway convertible car comprises two vibration damping airbags, a lifting airbag and an axle lifting valve. The upper ends of the two vibration damping airbags are connected with a centre sill component of a frame, the lower ends of the two vibration damping airbags are connected with an axle, the upper end of the lifting airbag is connected with the centre sill component, and the lower end of the lifting airbag is connected with the axle through a lifting lever. The suspension vibration damping system also comprises an axle holding mechanism. The axle holding mechanism comprises a lifting connection plate, a cross bar of which one end is connected with one end of the lifting connection plate, multiple safety hooks arranged on the cross bar in the axial direction of the cross bar, a lifting bolt hole formed in the upper part of the lifting connection plate and matched with a fixing hole in the centre sill component, and a lifting bolt, and the other end of the cross bar penetrates through the centre sill component. The decline of a highway tyre under the effect of dead-weight after being lifted is limited by using the axle holding mechanism, the highway tyre is fixed at the position to which the highway tyre is lifted, the transportation requirement of the highway-railway convertible car is met, and the operation is simple, safe and reliable.

Description

technical field [0001] The invention relates to the field of parts and components for railway wagons, in particular to a suspension vibration damping system for road and rail vehicles. Background technique [0002] The road-rail vehicle is actually a large-scale road container semi-trailer, which is installed on the railway bogie, using coil springs or hydraulic devices to lift the tires of the car to run on the railway line, or loaded by a road container trailer. The railway bogie constitutes a railway vehicle, and the railway bogie only needs to be raised or removed when driving on the road. Because during railway transportation, road tires need to be lifted to a height above the rails to meet the requirements of the railway boundary, road tires often fall down under their own weight, thereby causing harm to the operation of iron wheels. Contents of the invention [0003] The object of the present invention is to address the deficiencies of the above-mentioned technolog...
