Embodiment Construction

[0010] like figure 1 As shown, a pit-vibration railway vehicle base includes: an underframe 1, a fixed frame 2, a wheel 3, an axle 4, a spring 5, a damping device 6 and a shear pin 7; There are a plurality of fixed mounts 2, and the fixed mounts 2 are connected with wheels 3 through the axles 4, and the two sides of the fixed mounts 2 are provided with shock absorbers 6, and the shock absorber 6 has springs 5, and the shock absorbers A shear pin 7 is installed in the middle of the spring 5 of the device 6 .

[0011] An intermediate hydraulic shock absorber is arranged in the middle of the underframe 1 .

[0012] The bottom frame 1 and the fixed frame 2 are connected by riveting first, and then fixed by welding.

[0013] The base of a pit-vibration railway vehicle according to the present invention is provided with a shear pin in the damping device with a spring, and when the base device suddenly receives a relatively large pressure, the spring on the damping device is presse...

Abstract

The invention discloses a vibration absorbing for a railway vehicle. The vibration absorbing for the railway vehicle comprises a bottom frame, fixing frames, wheels, axles, springs, vibration absorbing devices and shearing pins; a plurality of fixing frames are oppositely uniformly arranged at two sides of the bottom frame; the wheels are connected to the fixing frames through the axles; the vibration absorbing devices are arranged at two sides of the fixing frames; the springs are arranged on the vibration absorbing devices; the shearing pins are mounted in the middles of the springs on the vibration absorbing devices. According to the vibration absorbing for the railway vehicle, the shearing pins are arranged in the vibration absorbing devices with the springs and can be used for bearing to preventing the vibration absorbing devices from being damaged by the suddenly increased pressure; in addition, the railway vehicle can continue to the work after earthquake, and therefore, the economic benefit is increased.

Description

technical field [0001] The invention relates to a pit-vibration railway vehicle base. Background technique [0002] Railway vehicles are vehicles for transporting passengers and goods. Over the years, due to different purposes, uses and operating conditions, vehicles have formed many types, but their structures are basically the same, and generally consist of six parts: ① car body: it is a place for accommodating transport objects, and it is also a place for installing and connecting other vehicles. The basis of the component. ②Car body frame: It is a rectangular frame that supports the car body and is the foundation of the car body. ③ Running part: It is the part that bears the weight and load of the vehicle and guides the vehicle along the track. Most of the running parts adopt bogie structure to ensure the running quality of the vehicle. ④ Coupler buffer device: It is composed of couplers, buffers and other components, and is installed at both ends of the underframe. ...
