【産業上の利用分野】[Industrial applications]

本考案は、クローラ走行装置や片側3輪以上の多輪走行装置等を具備した動力 車両における駐車ブレーキ装置に関する。 The present invention relates to a parking brake device in a power vehicle including a crawler traveling device and a multi-wheel traveling device having three or more wheels on one side.

【0002】[0002]

【従来の技術】[Prior art]

クローラ走行装置や多輪走行装置は、左右のクローラや車輪を各別に駆動停止 し得るよう動力伝動系を左右別々に設けている。このような左右別々の動力伝動 系を有する走行装置の駐車ブレーキ装置は左右の動力伝動系に別々の回転制御用 のブレーキ機構を設けた構成が一般的である。 In the crawler traveling device and the multi-wheel traveling device, a power transmission system is separately provided on the left and right sides so that the left and right crawlers and wheels can be individually stopped. Such a parking brake device for a traveling device having separate left and right power transmission systems generally has a configuration in which left and right power transmission systems are provided with separate brake mechanisms for rotation control.

【0003】[0003]

【考案が解決しようとする課題】[Problems to be solved by the device]

左右の動力伝動系を別々に制動する従来の構成では、左右の制動機構が均等に 働くようにしなければならなく構成が複雑になる。 そこで、本考案では比較的簡単な構成で左右の動力伝動系を確実に制動できる 駐車ブレーキ装置を提供することを課題とする。 In the conventional configuration in which the left and right power transmission systems are braked separately, the left and right braking mechanisms must be made to work equally, which complicates the configuration. Therefore, an object of the present invention is to provide a parking brake device capable of reliably braking the left and right power transmission systems with a relatively simple structure.

【0004】[0004]

【課題を解決するための手段】[Means for Solving the Problems]

左側走行装置13を駆動する左側ギヤ伝動系86と右側走行装置13を駆動す る右側ギヤ伝動系87を設けた動力車両において、左側走行装置13と右側走行 装置13の走行方向が逆方向となる関係に左側ギヤ伝動系86と右側ギヤ伝動系 87を連結する駐車ギヤ52を設けて動力車両の駐車ブレーキ装置を構成した。 また、左側走行装置13の操向変速レバー7と右側走行装置13の操向変速レ バー7が共に停止位置で駐車ギヤ52を操作可能に駐車レバー19を設けた。 In a power vehicle provided with a left gear transmission system 86 that drives the left traveling device 13 and a right gear transmission system 87 that drives the right traveling device 13, the traveling directions of the left traveling device 13 and the right traveling device 13 are opposite to each other. In relation to this, the parking gear 52 that connects the left gear transmission system 86 and the right gear transmission system 87 is provided to form a parking brake device for a power vehicle. Further, the parking lever 19 is provided so that the parking gear 52 can be operated when both the steering gearshift lever 7 of the left traveling device 13 and the steering gearshift lever 7 of the right traveling device 13 are in the stopped position.

【考案の作用及び効果】[Operation and effect of the device]

左右の走行装置13,13はそれぞれ駆動源につながる左側ギヤ伝動系86と 右側ギヤ伝動系87で駆動されている。 両ギヤ伝動系86,87と駆動源との間にクラッチを設けている場合には、ク ラッチを切った際には左右の走行装置13,13をそれぞれ制動しなければなら ない。またクラッチを設けず油圧駆動源に両ギヤ伝動系86,87を連結してい る場合にも、坂道停止など強い制動力を必要とする場合には同様に左右の走行装 置13,13を制動しなければならない。 本考案では制動する場合には、左右のギヤ伝動系86,87を左右の走行装置 13,13が逆回転となるよう駐車ギヤ52で噛み合わせるのであるから、左右 の走行装置13,13を各別に制動する構成よりも簡単であり、左右の制動力を バランスするよう調整する機構も不要である。 The left and right traveling devices 13, 13 are driven by a left gear transmission system 86 and a right gear transmission system 87, which are connected to a drive source, respectively. When a clutch is provided between the two gear transmission systems 86, 87 and the drive source, the left and right traveling devices 13, 13 must be braked when the clutch is disengaged. Even when both gear transmission systems 86 and 87 are connected to the hydraulic drive source without a clutch, the left and right traveling devices 13 and 13 are similarly braked when strong braking force is required such as when stopping on a slope. Must. In the present invention, when braking, the left and right gear transmission systems 86, 87 are engaged by the parking gear 52 so that the left and right traveling devices 13, 13 rotate in reverse. It is simpler than the separate braking structure and does not require a mechanism for adjusting the left and right braking forces to balance.

【0006】 尚、左側ギヤ伝動系86と右側ギヤ伝動87は別々に回転するので、両方が停 止した場合に駐車ギヤ52を噛み合わせる必要があるが、操向変速レバー7,7 を両ギヤ伝動系86,87を停止させる状態にした場合に駐車レバー19を操作 可能としているので、両ギヤ伝動系86,87を駐車ギヤ52で安全に連結でき 駐車状態となる。Since the left-side gear transmission system 86 and the right-side gear transmission 87 rotate separately, it is necessary to mesh the parking gear 52 when both stop. Since the parking lever 19 can be operated when the transmission systems 86 and 87 are stopped, both gear transmission systems 86 and 87 can be safely connected by the parking gear 52 and the parking state is established.
