Forced guiding mechanism of independent wheel pair two-axle bogie articulated car

Abstract

The invention relates to a guider of independent wheel, on two-axle steering support hinge vehicle, wherein it is formed by guide arm, front vehicle connecting rod, front wheel connecting rod, back vehicle connecting rod, and back wheel connecting rod; one end of front vehicle connecting rod and the front wheel connecting rod are hinged at one side of middle point of guide arm, while one end of back vehicle connecting rod and the back wheel connecting rod are hinged at another side of middle point of guide arm; the middle point of guide arm is O; the hinge point between front vehicle connecting rod and guide arm is S; the hinge point of front wheel with the connecting rod and guide arm is C; the hinge point of back wheel with the connecting rod and guide arm is B; the hinge point between back vehicle connecting rod and guide arm A; its guide increment factor is eta=OB / OA=OC / OD=b / l, while b means half axial distance between the front and back wheels of steering support, I means half distance of vehicles. The invention can make independent wheel force the front and back wheels of steering support into radial position of curvature track.

Description

technical field [0001] The invention belongs to a bogie guiding mechanism, in particular to a forced guiding mechanism for a two-axle bogie with independent wheels. Background technique [0002] "Independent wheelset" is relative to "conventional overall wheelset". The left and right wheels of a conventional integral wheel set are press-fitted on both ends of an axle through interference fit. When the train is running, the axle rotates with the wheels, and the left and right wheels rotate synchronously. The left and right wheels of the independent wheel set are assembled on both ends of an axle through rolling bearings. When the train is running, the axle does not rotate, and the left and right wheels can rotate freely around the axle asynchronously. The front car body and the rear car body are hinged together by a articulated coupler, which is called a "articulated car". [0003] The biggest advantage of the independent wheel set is that it can greatly reduce the floor he...

Problems solved by technology

The premise of this theory is that the cross-section of the center of the fixed distance of the car body and the cross-section of the center of the wheelbase of the bogie must be on the radial line of the curved track. The cross-section of the center usually deviates from the radial line of the curved track at a certain angle, so it is impossible or impossible for the front and rear wheel sets of the forced-steering bogie to tend to the radial position of the curved track at the same time, which shows the guiding ability of the traditional forced-steering bogie have a birth defect
