Abstract
The utility model discloses an air storage type trailer axle which comprises an axle tube, wherein a hub is respectively arranged on shaft heads at two ends of the shaft tube, and a brake is arranged on each hub. A shaft tube end socket is respectively welded at two ends in the shaft tube, a sealing cavity is formed between the shaft tube and the two shaft tube end sockets, compressed air used by a braking system is stored in the sealing cavity, and the sealing cavity in the middle of the shaft tube is connected with a trailer braking pipeline through a joint. The air storage type trailer axle is ingenious in structural improvement, the sealing cavity in the shaft tube is used for storing the compressed air needed by the braking system, and therefore air storage tank groups of the existing trailer braking system can be reduced in quantity or replaced, kerb weight is reduced, and loading space is effectively enlarged.
Description
Technical field
The utility model relates to the trailer vehicles technical field, mainly is a kind of air storing type Trailer car shaft.
Background technology
Trailer generally adopts compression air brake, and the required pressurized air of brake system is from one or more groups storage tank, and volume is larger.Limited by trailer structure, often cause storage tank group difficult arrangement on trailer, storage tank group and brake system are distant, cause the air connecting line to arrange that distance is longer, have certain potential safety hazard.
The utility model content
Technical problem to be solved in the utility model provides a kind of air storing type Trailer car shaft, it utilizes central siphon enclose inside cavity to store the required pressurized air of brake system, so that system layout is simple and easy, effectively shorten brake system pipeline distance, improve vehicle safety.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of air storing type Trailer car shaft, include central siphon, be separately installed with wheel hub on the spindle nose at central siphon two ends, drg is installed on the wheel hub, it is characterized in that: two ends are welded with respectively the central siphon end socket in the described central siphon, form enclosed cavity between central siphon and the diaxon channel closure, store the pressurized air for brake system in the enclosed cavity, the enclosed cavity in the middle of the described central siphon is by joint and trailer braking protection valve pipeline connection.
Enclosed cavity in the middle of corresponding on the described central siphon is provided with draining blowdown valve union, is communicated with draining blowdown valve pipeline by draining blowdown valve union.
Utilize the trailer axle tube internal cavities to store the required pressurized air of brake system in the utility model, can reduce or substitute the storage tank group of original trailer brake system, alleviate dead weight of vehicle, increase the efficient loading space.
The utility model has the advantages that:
The utility model structural development is ingenious, utilizes central siphon enclose inside cavity to store the required pressurized air of brake system, can reduce or substitute the storage tank group of original trailer brake system, alleviates dead weight of vehicle, increases the efficient loading space.
