Abstract
The utility model discloses a coupling mechanism for a traction beam and a front axle of a trailer, which solves the problem that the trailer can not brake in running. In the utility model, the hinged part of a traction beam (5) and a front axle lug (2) fixed to the front axle (1) of the trailer is made into a slot (4) which can be made on the traction beam or on the front axle lug. The slot (4) enables the traction beam to swing around a traction beam lug pin (3) and move back and forth, and the length of the slot (4) limits the distance of the back-and-forth movement. When the trailer runs, the brake speed of a front truck is lower than that of a back truck, and a traction beam towing hook of the back truck collides with a towing hook lug (8) of the front truck to cause the traction beam to move backward along the slot. Thereby, the positions of the traction beam, the front axle and the front axle lug generate front and back displacement to drive control elements of a pull wire, a brake pump, a brake rod, etc. and realize the braking of the back truck in running. In this way, the coupling mechanism for a traction beam and a front axle has the effects of simple structure, high safety and realization of reliable brake control of the trailer in running.
Description
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, trailer traction beam and the preceding shaft connection mechanism that can realize collision brake when trailer is advanced specifically is provided.
Background technology
The capable packet trailer that transports row bag, mail use in present each Railway station, the postal transfer point field is because frequent grouping operation, the towing hook hangers of draw beam gib head and front tractor-trailer is plucked, hangs frequent, draw beam is hinged by circular hole with the front axle hangers that is fixed on the trailer front axle by draw beam hangers pin, therefore draw beam can only be swung around draw beam hangers pin, and is simple in structure, light.Braking can not be braked when advancing when this trailer was only parked, and had potential safety hazard during use.
The utility model content
The utility model provides a kind of trailer traction beam and preceding shaft connection mechanism, solves the problem that can not brake when trailer is advanced.
Described draw beam makes slotted hole with the front axle hangers hinged place that is fixed on the trailer front axle, slotted hole can be done on draw beam, also can do on the front axle hangers, and draw beam can not only be swung around draw beam hangers pin, and can move forward and backward, the limitation of length of slotted hole the distance that moves forward and backward.
The utility model makes this trailer traction beam and preceding shaft connection mechanism have following beneficial effect owing to adopt the structure that trailer traction beam and trailer front axle hangers hinged place is made slotted hole:
1, simple in structure;
2, safe and reliable;
Effective control of braking when 3, realizing advancing.
Description of drawings
Fig. 1 is the integral structure scheme drawing of the utility model embodiment;
Fig. 2 is trailer front axle and the draw beam part plan structure scheme drawing of the utility model embodiment;
The specific embodiment
To trailer traction beam and preceding shaft connection mechanism that the utility model provides, accompanying drawings is as follows:
As Fig. 1, Fig. 2, shown in, a kind of trailer traction beam and preceding shaft connection mechanism, it comprises draw beam 5, one end of this draw beam 5 is a draw beam gib head 6, this draw beam gib head 6 flexibly connects by front truck towing hook pin 7 and front truck towing hook hangers 8, wherein: the slotted hole 4 of the other end of described draw beam 5 by making, hinged by draw beam hangers pin 3 and trailer front axle hangers 2, trailer front axle hangers 2 is fixed on the trailer front axle 1.
The slotted hole 4 of the utility model embodiment by trailer traction beam 5 and trailer front axle hangers 2 hinged places are made is connected with trailer front axle hangers 2 usefulness draw beam hangers pins 3, the limitation of length of slotted hole 4 distance that moves forward and backward of draw beam 5 and trailer front axle hangers 2.
The trailer middle front truck glancing impact of advancing, speed is lower than the back car, draw beam gib head 6 bumps with front truck towing hook hangers 8, draw beam 5 is moved along draw beam hangers pin 3 backward by slotted hole 4, make draw beam 5 and trailer front axle hangers 2 and trailer front axle 1 produce the front and back displacement, displacement drives control elements such as backguy, brake pump, brake rod and realizes back car braking thus.
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, approximate, identical person such as structure all and of the present utility model, device, feature all should belong within the patent scope of the present utility model.
Claims (4)
1, a kind of trailer traction beam and preceding shaft connection mechanism, by the front axle hangers (2) that is fixed on the trailer front axle (1), draw beam hangers pin (3), draw beam (5) is formed, one end of this draw beam (5) is draw beam gib head (6), this draw beam gib head (6) flexibly connects by front truck towing hook pin (7) and front truck towing hook hangers (8), it is characterized in that: the described draw beam other end is connected by slotted hole (4) with front axle hangers (2) by draw beam hangers pin (3).
2, according to described trailer traction beam of claim 1 and preceding shaft connection mechanism, it is characterized in that: described slotted hole is located on the draw beam.
3, according to described trailer traction beam of claim 1 and preceding shaft connection mechanism, it is characterized in that: described slotted hole is located on the front axle hangers.
