Abstract
The utility model relates to an independent wheel axle beam used for an independent wheel bogie truck, and the independent wheel axle beam comprises an independent wheel, an end axle and a cambered axle. An inner bearing and an outer bearing are arranged in the independent wheel and the end axle, the inner side of the independent wheel is provided with a dustproof cover and a rear cover, the outer side of the independent wheel is provided with a press cover, a liner plate and a front cover, and a spacer sleeve is arranged between the inner and the outer bearings. The independent wheel axle beam is characterized in that the end axle is pressed and mounted into the cambered axle with an integral cast structure, and the end of the inner side of the end axle is provided with a press plate preventing looseness. The end axle of the independent wheel axle beam is pressed and mounted into the cambered axle with the integral cast structure, the end of the inner side of the end axle is provided with the press plate preventing looseness, so that the independent wheel axle beam has enough endurance strength, favorable manufacturability and no looseness of the end axle to ensure the safe operation of the independent wheel bogie truck.
Description
Technical field:
The utility model relates to a kind of independent axle bridge of independent wheel bogie, relates to especially that a kind of fatigue proof end axle is fastening, the independent axle bridge of operation security.
Background technology:
The independent axle bridge is the most critical parts of independent wheel bogie, existing independent axle bridge exists that the end axle is loosening, wheeling edge wearing is serious and problem such as cambered axle anufacturability difference, can not satisfy the requirement of urban low-floor light rail car safe operation, make City Rail Transit System lose the operation economy that should have.
Summary of the invention:
Technical problem to be solved in the utility model provides a kind of enough strength at repeated alternations that has, and manufacturability is good, and it is loosening that the end axle does not take place, and guarantees the independent axle bridge of the safe operation of independent wheel bogie, to overcome the defective that background technology exists.
The technical solution of the utility model is: comprise independent wheel, end axle, cambered axle, be provided with neck bearing and outer bearing between independent wheel and the end axle, the inboard of independent wheel is provided with dust protecting cap and bonnet, arranged outside gland, backing plate and the protecgulum of independent wheel, be provided with spacing sleeve between the interior outer bearing, it is characterized in that: the end axial compression installs in the cambered axle of an inblock cast structure, and end axle medial end is provided with anti-loosening pressing plate.
The axial compression of the utility model end installs in the cambered axle of an inblock cast structure, end axle medial end is provided with anti-loosening pressing plate, makes this independent axle bridge have enough strength at repeated alternations, and manufacturability is good, it is loosening that the end axle does not take place, and guarantees the safe operation of independent wheel bogie.
