Abstract
The utility model relates to a freight trailer, particularly to a freight trailer dragged by a front vehicle with one section or multiple sections. The utility model mainly solves the problem of inconvenience for turning. The utility model is composed of a trailer body (1), front wheels (2), rear wheels (3), a front axle (4), a rear axle (5), a traction rod (6), a front vertical shaft (7), a front deflector rod (8), a rear vertical shaft (9), a rear deflector rod (10), a slide way (11) and a sliding block (12), wherein the front axle is hinged with the sliding block by the front deflector rod, the sliding block is matched with the slide way, the rear deflector rod and the rear axle are fixed together and are hinged on the rear axle, and the rear deflector rod is hinged on the sliding block. The turning centers of the front vehicle and the trailer are on the same point, and the utility model also has the characteristics of reasonable structure, convenient turning, etc.
Description
The utility model relates to a kind of Freight trailer, and a joint or a more piece Freight trailer of a car traction particularly arranged.
At present, Freight trailer is made up of car body, front and back wheel, axletree, draw bar, preceding vertical shaft, and draw bar, front axle are fixed together, on the vertical shaft, when turning round, rotates front axle by draw bar before being hinged on, and makes front wheel turn, drives rear wheel and turns thereupon.The general joint trailer of hanging of a car of freight, what the wheel of a car and trailer was walked when turning round is not same track, turning radius is bigger, if a car is drawn the more piece trailer, turning radius needs very big, and it is very difficult to turn round on narrower road, can't realize sometimes turning round at all.The reason that causes this problem be a car and trailer when turning round, their turning center is not on same point, a car can turn round sometimes, and the trailer of back can not change.
The utility model purpose provides a kind of Freight trailer, reduces the turn radius of freight, makes the turning center of a car and trailer solve the problems referred to above that prior art exists on same point.
The technical solution of the utility model is:
Comprise car body, front and back wheel, front and back axletree, draw bar, preceding vertical shaft, preceding driving lever, back vertical shaft, back driving lever, slideway, slide block in the composition of trailer, slideway, preceding vertical shaft, back vertical shaft are fixed on the car body, draw bar, front axle are fixed together, be hinged on the preceding vertical shaft, front axle is hinged by preceding driving lever and slide block, slide block and slideway are complementary, and back driving lever fixedly is hinged on the back axle with back axle, and back driving lever is hinged on the slide block.
Adopt the utility model, when car traction trailer is turned right overhead, draw bar rotates, the drive front axle rotates, and slide block slides on slideway, drives back axle and rotates thereupon, the turning center of car and trailer is on same point, reduced the turn radius of freight, as long as a car can be turned, a joint or the more piece trailer of back can pass through.
The turning center that the utlity model has rational in infrastructure, car and trailer on same point, the characteristics such as convenient of turning.
Structural representation when Fig. 1 does not turn for the utility model embodiment trailer.
Fig. 2 is a structural representation after the utility model embodiment trailer is turned.
Below in conjunction with accompanying drawing, further specify the utility model by embodiment.
Among the embodiment, the utility model is by car body (1), front vehicle wheel (2), rear wheel (3), front axle (4), back axle (5), draw bar (6), preceding vertical shaft (7), preceding driving lever (8), back vertical shaft (9), back driving lever (10), slideway (11), slide block (12), preceding slide bar (13), back slide bar (14) is formed, slideway, preceding vertical shaft, back vertical shaft is fixed on the car body, draw bar, front axle is fixing together, be hinged on the preceding vertical shaft, front axle is by preceding driving lever and preceding slide bar sliding block joint, preceding slide bar and slide block are hinged, slide bar one end and preceding driving lever sliding block joint promptly, the other end and slide block are hinged, slide block and slideway are complementary, back driving lever fixedly is hinged on the back axle with back axle, back driving lever and back slide bar sliding block joint, back slide bar is hinged on the slide block, slide bar one end and back driving lever sliding block joint promptly, the other end and slide block are hinged.When car traction trailer is turned right overhead, draw bar rotates, the drive front axle rotates, before driving lever drive slide block by preceding slide bar and on slideway, slide, preceding slide bar by and preceding driving lever between slip, regulate length, adapt to the slip of slide block, slide bar, back driving lever, back axle rotated thereupon after slide block drove, and the turning center of a car and trailer has reduced the turn radius of freight on same point.
