Non-power single-axle bogie and rail engineering vehicle

Abstract

The embodiment of the invention provides a non-power single-axle bogie and a rail engineering vehicle, which relate to railway maintenance mechanical equipment, and aim to solve the problems that thelayout space of all parts at the lower part of a vehicle body is limited and the manufacturing cost of the whole vehicle is relatively high due to a two-axle or three-axle bogie in related technologies. The non-power single-axle bogie comprises a framework, a wheel set, a primary suspension device, a secondary suspension device, a traction device, balance rod devices and a basic brake device, wherein the wheel set is provided with an axle, wheels mounted to the axle, and an axle box mounted to the axle; the primary suspension device is used for mounting the axle box on the framework; the secondary suspension device is used for connecting the framework with a vehicle body; the traction device is located on the lower side of the framework and used for connecting the framework with a vehiclebody; the balance rod devices are respectively arranged at the front end and the rear end of the framework and are used for connecting the framework with a vehicle body; and the basic brake device isprovided with a brake cylinder, a lever assembly and a brake shoe, and the brake cylinder drives the brake shoe to press the wheel through the lever assembly.

Description

technical field [0001] The application relates to railway track maintenance machinery and equipment, in particular to a non-powered single-axle bogie and a track engineering vehicle. Background technique [0002] Rail engineering vehicles, such as shunting locomotives and road maintenance locomotives, usually include: car body, on-board equipment and bogies; The equipment is installed on the car body or bogie, and the on-board equipment is used to perform corresponding operations. In the related art, the bogies of rail engineering vehicles are usually equipped with two or three bogies, and the two-axle or three-axle bogies are used, which leads to the limited space for the layout of the components in the lower part of the car body, and the manufacturing cost of the whole vehicle is relatively high. high. Contents of the invention [0003] The embodiment of the present application provides a non-powered single-axle bogie and a rail engineering vehicle, which are used to o...
