【発明の詳細な説明】
(a)産業上の利用分野
本発明はトラクタにて牽引されるトレーラ、とくにトラ
クタの連結器に連結されるトレーラ側のキングピンの分
野で利用されるものである。DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention is used in the field of trailers towed by tractors, particularly in the field of trailer-side kingpins connected to tractor couplers.
(b)従来の技術
一般にトラクタにてトレーラを牽引する輸送形態では、
トラクタの前輪からトレーラの後輪までの距離(以下小
イルベースという)は最大積載時の重量に応じて法規に
より定められている。(b) Conventional technology In general, in a mode of transportation in which a trailer is pulled by a tractor,
The distance from the front wheels of a tractor to the rear wheels of a trailer (hereinafter referred to as a small wheel base) is determined by law according to the maximum loaded weight.
例えば総重量(トラクタ、トレーラ及び積載物の合計)
が26トンの場合であればホイルベースは9.3m以上
が必要とされている。For example, total weight (total of tractor, trailer, and load)
If the weight is 26 tons, the wheelbase must be 9.3 m or more.
しかし、空車時にあっては総重量が小さくなるため、積
載時におけるホイルベースより短くしても法規上問題が
無い。However, since the total weight is smaller when the vehicle is empty, there is no legal problem even if the wheel base is shorter than when it is loaded.
(C)考案が解決しようとする問題点
ところが、従来の構造は連結器及びキングピンはそれぞ
れトラクタ及びトレーラに固定されているため、最大積
載時にセットされたホイルベースの長さは空車時でも変
更することができず、空車時における旋回半径が最大積
載時と同一となり、小廻りがきかないという欠点がおっ
た。(C) Problems that the invention aims to solve However, in the conventional structure, the coupler and king pin are fixed to the tractor and trailer, respectively, so the length of the wheel base set at maximum load cannot be changed even when the vehicle is empty. This resulted in the disadvantage that the turning radius when empty was the same as when fully loaded, making it difficult to turn around.
(d)問題点を解決するための手段
本発明は前記の如き欠点を解消するもので、車体の前部

。(d) Means for Solving the Problems The present invention solves the above-mentioned drawbacks by providing a kingpin at the front of the vehicle body that can be connected to a tractor coupler, and a wheel at the rear of the vehicle body. The present invention relates to a kingpin moving device for a trailer in which an upper plate having a kingpin vertically disposed on a pair of left and right longitudinal girders forming a part of the vehicle body is provided so as to be movable back and forth.
