Abstract

The utility model discloses a coupling structure of a traction beam and a front axle of a four-wheel three-pivot trailer, which is a trailer coupling structure having simple structure, convenient operation and collision brake control. The utility model comprises a traction beam, one end of which is a gib head of the traction beam. The gib head of the traction beam is movably connected with a towing hook hanger of a front truck through a towing hook pin of the front truck. The utility model is characterized in that a movable sleeve of the traction beam is provided with a rotating sleeve barrel, and the traction beam penetrates through the end of the rotating and is provided with a back stop of the traction beam. The rotating sleeve barrel is rotation sheathed on the front axle of the trailer, which makes the coupling structure of a traction beam and a front axle of a four-wheel three-pivot trailer have the advantages of simple structure, high safety and effective brake control.

Description

Four-wheel three fulcrum trailer traction beams and preceding shaft connection mechanism

Technical field

The utility model relates to a kind of trailer bindiny mechanism, and a kind of simple in structure, easy to use and reliable, four-wheel three fulcrum trailer traction beams and preceding shaft connection mechanism of realizing collision brake specifically is provided.

Background technology

Four-wheel three fulcrum trailers are that a kind of station, harbour, goods yard, factory, postal transfer point field, warehouse etc. of being widely used in are used for the vehicle that transports goods by self-propelled vehicle, braking when yet this vehicle is generally only parked at present, braking when not advancing, thus, in traveling process, can not in time brake, bring a lot of inconvenience to the user.

The utility model content

The purpose of this utility model is to remedy the inconvenience that trailer is braked in traveling process, and a kind of simple in structure, easy to use and reliable control of braking mechanism is provided, thereby realizes the braking effect of trailer in traveling process.

In order to achieve the above object, the utility model provides a kind of four-wheel three fulcrum trailer traction beams and preceding shaft connection mechanism, it includes draw beam, one end of this draw beam is the draw beam gib head, this draw beam gib head flexibly connects by front truck towing hook pin and front truck towing hook hangers, wherein: described draw beam movable sleeve is provided with rotational sleeve, and the end that this draw beam wears out rotational sleeve is provided with backstop behind the draw beam, and this rotational sleeve turning set is located on the front axle of trailer.

Backstop is fixed on the draw beam behind the draw beam, limited the draw beam end position of displacement forward, the front truck retro-speed was lower than the back car when trailer was advanced, back car draw beam and front truck towing hook bump and draw beam are moved forward and backward in rotational sleeve, the position of draw beam and two rotational sleeves and front axle is changed, drive control elements such as backguy, brake pump, brake rod thus, realize back car braking.

The utility model is owing to adopt sheathed rotational sleeve on the trailer front axle, and draw beam wears the structure of rotational sleeve, makes these four-wheel three fulcrum trailer traction beams and preceding shaft connection mechanism have following beneficial effect:

1, simple in structure;

2, safe and reliable;

3, realize advancing effective control of braking.

Description of drawings

Fig. 1 is the integral structure scheme drawing of the utility model embodiment;

Fig. 2 is the plan structure scheme drawing of the utility model embodiment;

Fig. 3 is the local structure scheme drawing of the utility model embodiment.

The specific embodiment

For the clear structure of the present utility model of your inspector is formed, and the overall operation mode, conjunction with figs. is described as follows now:

As Fig. 1, Fig. 2, shown in Figure 3, a kind of four-wheel three fulcrum trailer traction beams and preceding shaft connection mechanism, it includes draw beam 1, one end of this draw beam 1 is a draw beam gib head 2, this draw beam gib head 2 flexibly connects by front truck towing hook pin 3 and front truck towing hook hangers 4, wherein: described draw beam 1 movable sleeve is provided with rotational sleeve 5, and the end that this draw beam 1 wears out rotational sleeve 5 is provided with backstop 6 behind the draw beam, and these rotational sleeve 5 turning sets are located on the front axle 7 of trailer.

Two rotational sleeves 5 of the utility model embodiment by being sleeved on the trailer front axle 7 and can rotating on front axle 7 wear rotational sleeve 5 respectively with draw beam 1, and limit the displacement limits that draw beams 1 move forward by backstop behind the draw beam 6.

The trailer middle front truck glancing impact of advancing, speed is lower than the back car, draw beam gib head 2 bumps with front truck towing hook hangers 4 and draw beam 1 is subjected to displacement in rotational sleeve 5 backward, the draw beam 1 and the position of rotational sleeve 5 and front axle 7 are changed, drive control elements such as backguy, brake pump, brake rod thus and realize back car braking.

In sum, the utility model from application target, on the usefulness, viewpoint such as progressive and novelty sets forth, the practical improvement that it has, function enhancement and practical important document that novel patent law is emphasized have been accorded with, shown in the implementation and accompanying drawing that the utility model is above, be one of the utility model preferred embodiment, be not to limit to the utility model with this, be with, such as with approximate, identical person such as structure of the present utility model, device, feature, all should belong to of the present utility model founding within purpose and the claim.

Claims

1, a kind of four-wheel three fulcrum trailer traction beams and preceding shaft connection mechanism, it includes draw beam, one end of this draw beam is the draw beam gib head, this draw beam gib head flexibly connects by front truck towing hook pin and front truck towing hook hangers, it is characterized in that: described draw beam movable sleeve is provided with rotational sleeve, the end that this draw beam wears out rotational sleeve is provided with backstop behind the draw beam, and this rotational sleeve turning set is located on the front axle of trailer.
