| description | To provide a work vehicle that is able to apply a stable brake force to a rotating body.SOLUTION: In a left HST 31L, a hydraulic pump 41L and a hydraulic motor 42L are connected by a first oil passage 43L and a second oil passage 44l so that hydraulic oil circulates between the hydraulic pump 41L and the hydraulic motor 42L. Its closed circuit is connected to a charging oil passage 23 to which hydraulic pressure is supplied from a charging pump 21. The same applies to a right HST 31R. A parking brake 71 is a negative brake and is configured such that a rotating body that rotates during traveling is braked by urging force of a brake spring 72 and the brake is released by hydraulic pressure supplied from a brake oil passage 74. The brake oil passage 74 is supplied with hydraulic pressure from the charging oil passage 23.SELECTED DRAWING: Figure 3
【課題】安定した制動力を回転体に付与できる、作業車両を提供する。【解決手段】左側ＨＳＴ３１Ｌでは、油圧ポンプ４１Ｌと油圧モータ４２Ｌとの間で作動油が循環するように、油圧ポンプ４１Ｌと油圧モータ４２Ｌとが第１油路４３Ｌおよび第２油路４４Ｌで接続されており、その閉回路は、チャージポンプ２１から油圧が供給されるチャージ油路２３に接続されている。右側ＨＳＴ３１Ｒについても、同様である。駐車ブレーキ７１は、ネガティブブレーキであり、走行時に回転する回転体をブレーキばね７２の付勢力により制動し、その制動をブレーキ油路７４から供給される油圧により解除する構成である。ブレーキ油路７４には、チャージ油路２３から油圧が供給される。【選択図】図３ |
