Novel connecting device of railway vehicle wheel axle

Abstract

The invention discloses a novel connecting device of a railway vehicle wheel axle, which comprises a left wheel, a connecting axle, a right wheel, a left wheel-axle connecting bearing, a right wheel-axle connecting bearing, a left load-bearing bearing and a right load-bearing bearing, wherein the left load-bearing bearing is connected with the left-side head part of the connecting axle; the right load-bearing bearing is connected with the right-side head part of the connecting axle; the left wheel is connected with the connecting axle through the left wheel-axle connecting bearing; the right wheel is connected with the connecting axle through the right wheel-axle connecting bearing.

Description

technical field [0001] The invention relates to a connection device of a wheel shaft of a railway vehicle, in particular to a new connection in which the wheel shaft is connected separately through a pair of bearings on each side. Background technique [0002] At present, the well-known railway vehicle axle is an integrated device, that is, the angular velocity of the two wheels and the axle is equal, and the distance traveled by the left and right wheels is equal when the wheels are running in a straight line, but when they enter a curved section, the distance traveled by the left and right wheels will appear. Not equal, but the diameter of the left and right wheels is equal, the integrated axle, the distance traveled by the left and right wheels is not equal, the distance traveled by the outer wheel of the curve is longer than the distance traveled by the inner wheel of the curve, which will cause uneven wear on the left and right wheels, especially the curve The two stran...

Problems solved by technology

[0002] At present, the well-known railway vehicle axle is an integrated device, that is, the angular velocity of the two wheels and the axle is equal, and the distance traveled by the left and right wheels is equal when the wheels are running in a straight line, but when they enter a curved section, the distance traveled by the left and right wheels will appear. Not equal, but the diameter of the left and right wheels is equal, the integrated axle, the distance traveled by the left and right wheels is not equal, the distance traveled by the outer wheel of the curve is longer than the distance traveled by the inner wheel of the curve, which will cause uneven wear on the left and right wheels, especially the curve The two strands of steel rails produce uneven wear, the lower strand rails are crushed, and the upper strand rails are worn sideways. It costs a lot to change the railway track every year, especially when the passenger train enters the curve operation, the high-speed railway, high-speed train, and speed-up train will produce serious vibration and bumps , the comfort of passengers is greatly reduced, and the loss of kinetic energy is serious. At present, the integrated device of the axle of the railway vehicle cannot overcome these disadvantages
