Embodiment Construction

[0014] The connection mechanism between the trailer draw beam and the front axle provided by the present invention is described as follows in conjunction with the accompanying drawings:

[0015] As shown in Fig. 1, Fig. 2 and Fig. 3, a trailer traction beam and front axle connection mechanism, which includes front wheel 1, traction beam limit stop 2, rotating sleeve 3, trailer front axle 4, front axle and The vehicle surface connection mechanism 5, the traction beam 6, the traction beam hook head 7, the front vehicle tow hook lug pin 8, the front vehicle tow hook lug 9, and the vehicle surface 10 form. One end of the draw beam 6 is a draw beam hook head 7, which is movably connected with the front car tow hook lug 9 through the front car tow hook pin 8, wherein: the draw beam 6 is connected to the trailer front axle 4 The two ends of the connecting end respectively move through the sleeve formed by the hole above the rotating sleeve 3. The drawing beam 6 passes through the end...

Abstract

A coupling mechanism between the drag beam and front axle of trailer for the collision braking control is disclosed. The hook at one end of drag beam is pinned with the on the drag hook of front car and two heads at its another end are inserted in two holes of rotary sleeve on said front axle with a rotary limiter. When the front car is braked, the collision between the drag hook and drag beam can make the rotary sleeve to be turned by a certain angle, which can drive the brake system of trailer for braking it.

Description

technical field [0001] The invention relates to a trailer connection mechanism, and specifically provides a trailer traction beam and front axle connection mechanism which is simple in structure, convenient and reliable in use, and can realize collision braking when the trailer travels. Background technique [0002] At present, the luggage and trailers used in railway stations and postal transfer stations for transporting luggage and mail are often marshalled, and the hook head of the traction beam is frequently removed and hung from the lugs of the tow hook of the towed vehicle in front. The heads are hinged respectively through the lug pins of the traction beam and the lugs of the traction beam fixed on the front axle of the trailer, so the traction beam can only swing around the lug pins of the traction beam, and the structure is simple and light. Due to the requirement that the towing beam must be simple and portable, this trailer only has to brake when it is parked at p...
