Embodiment Construction

[0011] like figure 1 , which is an embodiment of a train coaxial unequal speed energy-saving wheel of the present invention, one side of the train axle 12 is a stationary wheel 13 (relative to the train axle), and the other side is a live wheel. On the side of the live wheel, the bearing of the live wheel body 7 that bears the main load is the sliding bearing 8. The axial direction of the two sides of the sliding bearing 8 is provided with a thrust bearing 6, and the outer side of the live wheel body 7 is provided with a locking ring 4 and an outer end from the inside to the outside. Cover 3, dustproof sealing ring 1, locking ring 4 is fixed by the locking ring loosening screw 5, the outer end cover 3 is fixed by tightening the hexagon socket head bolt 2, the inner side of the live wheel body 7 is provided with an inner end cover 9 from the inside to the outside , sealing ring 10, dust ring 11.

[0012] The treads of the two wheels can be cylindrical or conical.

Abstract

The invention relates to a coaxial and variable-speed energy-saving wheel of a train. One wheel at one side of a train shaft is a static wheel (relative to the train shaft), and the other side of the train shaft is provided with a movable wheel which can rotate around the shaft of the static wheel; and when the train runs, the relative rotating speed of two wheels is extremely low, thus the movable wheel is basically in a static load state. The running friction of the wheel is less, therefore, a sliding bearing is selected to serve as the bearing for bearing main load. Thrust bearings are selected in the axis direction of the two sides of the sliding bearing so as to be used for balancing axial forces generated due to leftward and rightward swinging when the train runs. When the train with the coaxial and variable-speed energy-saving wheel passes through a bend, no strict requirement is needed for turning radius, rolling friction instead of sliding friction is realized between the two wheels and iron rails, the wheels are avoided from generating sliding friction to consume energy and generate harsh noise, and no axial force is generated when in braking.

Description

technical field [0001] The invention relates to a train coaxial wheel. Background technique [0002] At present, the two wheels of the train are a fixed shaft. The problem is that the contact surface between the wheel and the rail is different, which is professionally called the tread. The tread of the wheel has a slope (the tread part of the wheel is a part of the cone), which is small on the outside and large on the inside. When the train turns, due to the centrifugal force, the outside of the wheel tread with a large slope (the big end of the cone) contacts. The track is quite a large radius in circular motion, and the place where the inner wheel tread is small (the small head of the cone) is the smaller radius in circular motion, and the angular velocity of the two wheels is different (not referring to the rotation angular velocity of the two wheels). ), which makes the turn smoothly. When walking in a straight line, the treads of the wheels on both sides contact the m...
