Rail engineering vehicle bogie and rail engineering vehicle

Abstract

The invention discloses a rail engineering vehicle bogie and a rail engineering vehicle. The rail engineering vehicle bogie comprises wheel set axle box devices and a framework arranged on the wheel set axle box devices and used for supporting a vehicle body. The framework is elastically connected with the wheel set axle box devices through first elastic parts, and the framework is provided with second elastic parts used for elastically supporting the vehicle body. The framework is further provided with first supporting oil cylinders and second supporting oil cylinders, a cylinder body of each first supporting oil cylinder is fixedly connected with the framework, and a piston rod of each first supporting oil cylinder is used for abutting against the corresponding wheel set axle box device; a cylinder body of each second supporting oil cylinder is fixedly connected with the framework, and a piston rod of each second supporting oil cylinder is used for abutting against the bottom of the vehicle body. According to the rail engineering vehicle bogie and the rail engineering vehicle, operation precision and operation safety of the rail engineering vehicle can be guaranteed.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of mechanical structures, in particular to a bogie for a rail engineering vehicle and a rail engineering vehicle. Background technique [0002] Rail engineering vehicles are indispensable rail tools in the initial stage of construction and official operation of main railway lines and subways. They are mainly used for rail transit construction, line maintenance and testing to ensure the effective and stable operation of rail transit. [0003] The bogie is one of the important components of the rail engineering vehicle. Its main functions are: 1. Bear the weight of the parts above the frame; 2. Ensure the necessary adhesion; 3. Make the vehicle have good stability and stability during operation ; 4. Ensure that the vehicle passes through the curve smoothly; 5. Generate necessary braking force. Whether the parameters of each component of the bogie are reasonable will directly affect t...

AI Technical Summary

Problems solved by technology

[0004] The bogies of rail engineering vehicles in the prior art are mostly directly elastically supported between the wheel set and the frame and between the frame and the car body through the elastic primary suspension and the elastic secondary suspension respectively. The rigid state of the car body and the bogie cannot be guaranteed when the frame is used on rail engineering vehicles. During the operation, the car body will shake, which will easily affect the working accuracy, and some construction machinery with cantilever operations, such as catenary maintenance vehicles, may have Vehicle Overturn Hazard
