Abstract

The utility model relates to an axle, which comprises an axle body with an inner cavity, and is characterized in that end covers for sealing the inner cavity are respectively arranged at two ends of the axle body, an air inlet hole and an air outlet hole are arranged at the position of a non-bearing section of the axle body and communicated with the inner cavity, the air inlet hole is communicated with an air compressor by the aid of an air inlet pipe, and the air outlet hole is communicated with an axle brake device by the aid of an air outlet pipe. As the inner cavity of the axle body replaces an air storage cylinder, the axle saves the cost and the space of a semitrailer, lightens the weight of the semitrailer, can automatically detect whether the axle body is cracked or not, and is safer and more reliable in driving.

Description

A kind of axletree

Technical field

The utility model relates to a kind of axletree, relates in particular to the back bearing axle that a kind of superimposed trailer is used.

Background technology

The back bearing axle that existing conveying semi-trailer is used, mainly play the effect of supporting and braking, the required source of the gas of its brake equipment is from several air receivers that hang on the vehicle frame, and Air compressor provides pressurized air for air receiver, and the volume of each air receiver is approximately 20 liters, volume is bigger, each car generally needs three to four air receivers of adapted, has taken the more space of superimposed trailer, has also influenced the bearing capacity of superimposed trailer, and cost is also high, the function singleness of axletree.

The utility model content

The purpose of this utility model is to overcome the deficiencies in the prior art and provide a kind of closed cavity with axletree can replace air receiver, the pressurized air of being filled in the axletree inner chamber can satisfy the required operation pressure of axletree braking fully, save the cost and the space of superimposed trailer, reduce the weight of superimposed trailer, and can detect a kind of axletree whether axletree has crackle automatically.

In order to achieve the above object, the utility model is to realize like this, it is one one kinds of axletrees, comprise the axletree body of being with inner chamber, it is characterized in that: be respectively equipped with end cap at the two ends of axletree body bore seal, non-pressure-bearing section place at the axletree body is provided with induction opening and the air gate that is communicated with inner chamber, and induction opening is communicated with Air compressor by air inlet pipe, and air gate is communicated with the axletree brake equipment by freeing pipe.

Below the non-pressure-bearing section of described axletree body, be provided with drain gutter, be provided with the obstruction that can open or close at the drain gutter place.

First adapter sleeve that seals of connecting thread in described air inlet position is welded with band, second adapter sleeve that seals of connecting thread in the air gate place is welded with band.

Be welded with tapped the 3rd adapter sleeve that seals at described drain gutter place, stop up and the 3rd adapter sleeve screw thread fit.

The utility model advantage compared with prior art is, owing to replace air receiver with the axletree chamber body, the cost and the space of having saved superimposed trailer have reduced the weight of superimposed trailer, and can detect the axletree body automatically whether crackle is arranged, and drives safer, reliable.

The specific embodiment

Below in conjunction with drawings and Examples the utility model is further described:

Shown in Fig. 1 to 4, its a kind of axletree, comprise the axletree body 2 of being with inner chamber, characteristics of the present utility model are: be respectively equipped with the end cap 1 with bore seal at the two ends of axletree body 2, non-pressure-bearing section place at the axletree body is provided with induction opening 22 and the air gate 24 that is communicated with inner chamber 21, induction opening is communicated with Air compressor 6 by air inlet pipe 8, the pressurized air of Air compressor generation can enter in the inner chamber like this, air gate is communicated with the axletree brake equipment by freeing pipe 10, and emergency relay valve 11 also is installed on freeing pipe.During use, the pressurized air that Air compressor 6 is produced enters in the inner chamber 21 by air inlet pipe 8 and induction opening 22, enters the axletree brake equipment in car glancing impact pressurized air from air gate 24 axletree is braked.In the present embodiment, induction opening and air gate can be located at the side of the non-pressure-bearing section of axletree body, reduce the influence to axletree.

In the present embodiment, below the non-pressure-bearing section of axletree body 2, be provided with drain gutter 23, be provided with the obstruction 5 that can open or close at the drain gutter place, can emit the water in the inner chamber like this.

In the present embodiment, first adapter sleeve, 9, the first adapter sleeves that seal of connecting thread are connected by screw thread with the air extractor duct of air inlet pipe 8 in induction opening 22 places are welded with band; Second adapter sleeve, 4, the second adapter sleeves that seal of connecting thread are connected by screw thread with the air intake of freeing pipe 10 in air gate 24 places are welded with band; Be welded with tapped the 3rd adapter sleeve 3 that seals at drain gutter 23 places, stop up the 5 and the 3rd adapter sleeve screw thread fit.In the present embodiment, induction opening, portal and drain gutter distant apart from the bearing pressure position of axletree, can not exert an influence to the axletree body, do not influence the performance and the service life of axletree body.
