Description

Two-wheel foreign matter inlay card discharger after traction engine

【Technical field】

The utility model is related to the technical fields of automobile train, are arranged more particularly to two-wheel foreign matter inlay card after a kind of traction engine Go out device.

【Background technology】

The characteristics of traction engine is that loading capacity is big, and common single wheel can not provide enough support performances, so in vehicle When design, can select to carry out multiple rows of wheel to the trailing wheel with higher load-carrying requirement it is arranged side by side, to provide higher load-carrying Energy.

By taking two-wheel after common engineering truck as an example, wheel shaft both ends are respectively set there are two wheel arranged side by side, two wheels Wheel hub convex surface is mutually leaned on, and the brake disc of drum brake is arranged in the cavity of nearside wheel hub, and medial and lateral wheel hub passes through with brake disc Bolt is fixed on the bearing holder (housing, cover) of axle ends together；Since the end face of two wheel hub junctions is outer male structure, two wheels Gap with certain length between the adjacent tires end face of tire, according to the difference of wheel hub specification, when unloaded, between two tires Gap width be normally between 30-150mm, and full load, due to tire compressive deformation, between the adjacent surface of two tires A hourglass configuration can be formed, there is closest approach between tire tread, and the region on closest approach then forms approximate envelope The space structure closed；When the wheel of traction engine is by the more construction area of rubble, it is easy at the gap between rear two-wheel Inlay card is to crushed stone, if before crushed stone inlay card to tire and being clamped, in low speed, two tire end faces of rear two-wheel are specific Position can periodically be squeezed by rubble, and long meeting causes to wear to tire end face；If fast state downward driving, inlay card exist Foreign matter between tire can also randomness the rear direction got rid of to traction engine, the vehicle positioned at traction engine rear is caused greatly Danger；It, can be as the rotation of wheel be to wheel hub if stone inlay card is followed by pressed into the approximate closed area between tire It causes to scrape and generates noise.

By above-mentioned analysis it is found that the rear two-wheel of traction engine is after construction area inlay card foreign matter, it will to vehicle itself or Ambient enviroment generation seriously affects, and is a problem for needing emphasis to overcome.

Through retrieval, it is not yet found that disclosed technical solution reasonably solves the problem, and in practical application, people Install foreign matter of the iron plate stretched between tire between tire additional usually on vehicle frame and directly answer back to, it is this simple Structure the abrasion of tire tread on the one hand can be caused when fiercely answering back to, on the other hand, if foreign matter breaks away between wheel hub, very It is difficult to be answered back to iron plate end face, it can rest between tire for a long time, so being not a kind of preferable Resolving probiems side Formula.
