Description

Description: TECHNICAL FIELD The present invention relates to a connecting structure for a hood for a connected vehicle such as a connected bus.

[Prior art]

As shown in FIG. 1, a connecting vehicle such as a connecting bus surrounds a connecting portion between a front vehicle 1 and a rear vehicle 2 with a hood 3, and when turning, the front vehicle 1 and the rear vehicle 2 have an intermediate point O. When bent in the center, the hood on the turning center side contracts and the hood on the opposite side extends.

[Problems to be Solved by the Invention] However, since the above-described coupled vehicle does not have a guide for guiding the hoods on both sides in the middle, the amount of expansion and contraction of the hoods is not necessarily average, resulting in poor durability and unsightly appearance. There was a problem such as.

Therefore, an object of the present invention is to provide a connecting structure for a hood for a connected vehicle in which the expansion and contraction of the connecting hood is made uniform and the hood is smoothly operated to improve the durability of the hood and improve its appearance.

[Means for Solving the Problems]

To achieve the above object, the connecting structure for a hood for a connected vehicle according to the present invention connects a hood extending from a front vehicle and a rear vehicle via a mounting frame, and extends from a front vehicle and a rear vehicle. The turntables to be output are vertically stacked and rotatably arranged above the lower frame of the mounting frame, and the swivel axis of the mounting frame is inserted through the swivel center of the lower turntable. A link mechanism for turning the mounting frame is provided, the link mechanism is provided with a lever fixed to the turning shaft, a pair of links having the same length provided on both sides of the lever, and a lower turntable. An arm fixed to the upper turntable and an arm fixed to the upper turntable, and a long hole in the axial direction of the lever is formed in the lever to pivotally support one end of the pair of links. The pivotal support can be slid into the slot Engage, pivot the other end of one link to the arm of the lower turntable, pivot the other end of the other link to the arm of the upper turntable, and It is characterized in that the pivotal fulcrum of the other link with the arm is set at the same distance from the turning center.

[Action]

With such a configuration, one turntable turns with respect to the other turntable due to the bending of the front vehicle and the rear vehicle, and with this turning, the pivotal support portion between the ends of the links having the same length causes the length of the lever to increase. The lever is rotated while sliding in the hole, and the pivot shaft of the mounting frame is rotated together with the lever to pivot the mounting frame.

The turning angle of the mounting frame is half the bending angle of the front vehicle and the rear vehicle because the other ends of the links of the same length are pivotally supported by each turntable at the same distance from the turning center. Since the frame is always positioned between the front vehicle and the rear vehicle, the hood can be smoothly expanded and contracted when the vehicle turns, the durability of the hood is improved, and the appearance is improved.

3a are arranged symmetrically on both sides of one arm 41a of the lever 41.

On the other hand, the link mechanism 40b on the other side pivots one end of a pair of links 42b, 43b of the same length in the long hole portion 47b of the other arm 41b of the lever 41, similarly to the above-mentioned one side link mechanism 40a. The supported pin 48b is slidably engaged, the other end of the link 42b is pivotally supported on the other arm 44b of the arm 44 by a pin 49b, and the other end of the link 43b is connected to the other arm 46b of the arm 46 by a pin 50b. It is pivoted at
And the pin 49 which is the pivot point of the other arm 44b of the arm 44 of the link 42b.
