本発明は、前方フレームと後方フレームとを屈
折自在に連結した車体屈折式操舵装輪車両に関す
るものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a steering wheeled vehicle of a vehicle body refraction type in which a front frame and a rear frame are refractably connected.
従来、この種の車両としては第１図、第２図に
示すように、前輪１と作業機２とを備えた前方フ
レーム３と、後輪４を備えた後方フレーム５とを
センタピン６で屈折自在に連結し、前方フレーム
３に運転席７を設けた車両、第３図、第４図に示
すように運転席７を後方フレーム５に設けた車両
が知られている。 Conventionally, in this type of vehicle, as shown in FIGS. 1 and 2, a front frame 3 having a front wheel 1 and a work implement 2, and a rear frame 5 having a rear wheel 4 are bent at a center pin 6. Vehicles in which the driver's seat 7 is freely connected to the front frame 3, and vehicles in which the driver's seat 7 is provided in the rear frame 5 as shown in FIGS. 3 and 4 are known.
そして、前者の運転席７が前方フレーム３にあ
る車両においては、運転席６が前方フレーム３と
常に同一向きとなるので、走行時の前方視界が良
いと共に、作業機２を常に真直に目視できるから
作業性が良い。 In the former vehicle where the driver's seat 7 is located on the front frame 3, the driver's seat 6 always faces the same direction as the front frame 3, so the forward visibility is good while driving and the work equipment 2 can always be viewed straight. Good workability.
しかし、その反面に前後進時ともに車両の進行
方向が、スタート時の前方フレーム３に対する後
方フレーム５の角度θ1によつて決定されるので、
スタート時にはオペレータが後方を見て前記角度
θ1を確認しないとオペレータの意志と違う方向に
走行して危険であるから、常に後方を見る必要が
あるので、面倒であると共に、作業機２の振動が
大きくなる不具合を有する。 However, on the other hand, since the direction of movement of the vehicle in both forward and backward motion is determined by the angle θ 1 of the rear frame 5 with respect to the front frame 3 at the start,
If the operator does not look behind and confirm the angle θ 1 at the start, it will run in a direction different from the operator's intention, which is dangerous.As it is necessary to always look behind, it is troublesome and reduces the vibration of the work equipment 2. This has the problem of increasing the amount of damage.
また、後者の運転席７が後方フレーム５に設け
てある車両においては、運転席６が前方フレーム
３及び作業機２と異なる向きとなるので、前方視
界が悪いと共に、作業性が悪いが、オペレータは
運転席７より前方フレーム３を常に目視できて車
両の走行方向を常に認知できるとの利点を有す
る。 In addition, in a vehicle in which the latter driver's seat 7 is provided in the rear frame 5, the driver's seat 6 is oriented in a different direction from the front frame 3 and the work equipment 2, resulting in poor forward visibility and poor workability; This has the advantage that the front frame 3 can always be seen visually from the driver's seat 7, and the running direction of the vehicle can always be recognized.
この様に、運転席７が前方フレーム３に設けて
ある車両と後方フレーム５に設けてある車両とで
は、相反する利点と不具合とを有するので、通常
は作業条件やオペレータの好み等によつてどちら
かに決定しているが、他の作業条件や好みの異な
るオペレータが運転する場合には好ましくない。 As described above, vehicles in which the driver's seat 7 is provided in the front frame 3 and vehicles in which the driver's seat 7 is provided in the rear frame 5 have contradictory advantages and disadvantages, so it is usually determined by work conditions, operator preference, etc. Although one has been decided, it is not preferable if operators with different working conditions or preferences operate the system.
本発明は上記の事情に鑑みなされたものであ
り、その目的は、運転席を前方フレームと後方フ
レームとのどちらにでも選択的に取付けできるよ
うにした車体屈折式操舵装輪車両を提供すること
