Forced guide mechanism for bogie

Abstract

The invention discloses a forced guide mechanism for a bogie, which belongs to the technical field of structural design of locomotive vehicles and can effectively solve the problem of limitation of the distance between axles when a vehicle uses a forced guide frame. The forced guide mechanism comprises a vehicle body, a framework, a front guide rod for connecting a front cross beam and the vehicle body, and a rear guide rod for connecting a rear cross beam and the vehicle body, wherein one end of a left front pull rod is articulated on a left front axle box, and the other end of the left front pull rod is articulated at the left end of the front cross beam; one end of a right front pull rod is articulated on a right front axle box, and the other end of the right front pull rod is articulated at the right end of the front cross beam; one end of a left rear pull rod is articulated on a left rear axle box, and the other end of the left rear pull rod is articulated at the left end of the rear cross beam; one end of a right rear pull rod is articulated on a right rear axle box, and the other end of the right rear pull rod is articulated at the right end of the rear cross beam; the front cross beam is articulated in the position, deviating to the right, at the center of the framework, and the rear cross beam is articulated in the position, deviating to the left, at the center of the framework; one end of the front guide rod is articulated at the front end of the vehicle body, and the other end of the front guide rod is articulated on the front cross beam; and one end of the rear guide rod is articulated at the rear end of the vehicle body, and the other end of the rear guide rod is articulated on the rear cross beam. The forced guide mechanism is mainly used for manufacturing locomotive vehicles.

Description

technical field [0001] The invention belongs to the technical field of locomotive and vehicle structure design, in particular to the technical field of design and manufacture of locomotive and vehicle bogies. Background technique [0002] During the operation of railway locomotives in the curve section, the wheel-rail creep force realizes the radial position of the wheel set on the curve through the radial adjustment mechanism, which can effectively reduce the friction and wear of the wheel-rail, and the self-guiding bogie relies entirely on creep Force steering has certain limitations, and can only partially improve the curve passing performance, while the curve passing performance of the forced steerable bogie is better than that of the self-steering bogie. When the steerable bogie passes through the curve, the relative angular displacement between the car body and the bogie is used to force the wheelset to be in the radial position. At present, the relatively mature desig...

AI Technical Summary

Problems solved by technology

When the steerable bogie passes through the curve, the relative angular displacement between the car body and the bogie is used to force the wheelset to be in the radial position. At present, the relatively mature design schemes include the DEVINE-SCALE bogie in the United States. The levers they use connect the front and rear The length of the wheel shaft and the lever is related to the distance between the front and rear wheel shafts. If there is an intermediate wheel shaft and motor, the forced guide mechanism will be difficult to install
