Abstract:
(EN) A hydrostatic transmission includes a for-travel pump, a hydraulic circuit, and a for-travel motor. The for-travel pump is driven by an engine. The hydraulic circuit is connected to the for-travel pump. The for-travel motor is connected to the for-travel pump via the hydraulic circuit. A controller determines a target flow rate for the for-travel motor or the for-travel pump. The controller determines a correction amount for the target flow rate from the hydraulic pressure of the hydraulic circuit. The controller determines the target capacity of the for-travel motor or the for-travel pump from the target flow rate and the correction amount.
(FR) La présente invention concerne une transmission hydrostatique qui comprend une pompe de déplacement, un circuit hydraulique et un moteur de déplacement. La pompe de déplacement est entraînée par un moteur. Le circuit hydraulique est raccordé à la pompe de déplacement. Le moteur de déplacement est raccordé à la pompe de déplacement par l’intermédiaire du circuit hydraulique. Un dispositif de commande détermine un débit cible pour le moteur de déplacement ou la pompe de déplacement. Le dispositif de commande détermine une quantité de correction pour le débit cible à partir de la pression hydraulique du circuit hydraulique. Le dispositif de commande détermine la capacité cible du moteur de déplacement ou de la pompe de déplacement à partir du débit cible et de la quantité de correction.
(JA) 静油圧式変速機は、走行用ポンプと、油圧回路と、走行用モータとを含む。走行用ポンプは、エンジンによって駆動される。油圧回路は、走行用ポンプに接続されている。走行用モータは、油圧回路を介して走行用ポンプに接続されている。コントローラは、走行用モータ、又は、走行用ポンプの目標流量を決定する。コントローラは、油圧回路の油圧から、目標流量の補正量を決定する。コントローラは、目標流量と補正量とから、走行用モータ、又は、走行用ポンプの目標容量を決定する。
