The invention relates to the field of brake systems, and provides a hydraulic brake system and engineering machinery, comprising an oil supply device, n service brake assemblies and a foot valve. At least one service brake assembly comprises a relay valve and a wet brake, and the relay valve is arranged between the oil supply device and the wet brake. The foot valve is arranged between the oil supply device and the control end of the relay valve and used for controlling connection or disconnection of the oil supply device and the control end of the relay valve. When the oil supply device and the control end of the relay valve are connected through the foot valve, the oil supply device and the wet brake are connected through the relay valve. At the moment, the oil supply device can convey hydraulic oil to the wet brake through the relay valve, so that the wet brake is in a braking state. According to the hydraulic braking system, the relay valve is controlled by the foot valve to connect or disconnect the oil supply device and the wet brake, and when the relay valve connects the oil supply device and the wet brake, the oil supply device can provide sufficient hydraulic oil for the wet brake through the relay valve.
本发明涉及制动系统领域,提供一种液压制动系统和工程机械,包括供油装置、n个行车制动组件和脚踏阀。至少一个行车制动组件包括继动阀和湿式制动器,继动阀设置在供油装置与湿式制动器之间。脚踏阀设置在供油装置与继动阀的控制端之间,用于控制供油装置与继动阀的控制端的连通或断开。当脚踏阀导通供油装置与继动阀的控制端时,继动阀接通供油装置与湿式制动器。此时,供油装置可将液压油经继动阀输送至湿式制动器,使湿式制动器处于制动状态。本发明提供的液压制动系统通过脚踏阀控制继动阀导通或切断供油装置与湿式制动器的连通,当继动阀导通供油装置与湿式制动器时,供油装置可通过继动阀为湿式制动器提供充足的液压油。
