Abstract

The invention discloses a novel hydraulic motor transmission control valve bank which comprises an electromagnetic directional valve, a one-way throttle valve, a shuttle valve, an overlapped valve, a one-way valve and a ball valve, wherein each control valve is arranged on a junction valve block; a braking oil cylinder control valve adopts a shuttle valve built-in type two-way cartridge valve cover board; the junction valve block is arranged on the upper part of a drip pan; the inside of the junction valve block has a plurality of channels and oil holes; moreover, one side of the drip pan is provided with a fixing device. The novel hydraulic motor transmission control valve bank which has a simple structure can be arranged near the transmission device of a hydraulic motor, thereby reducing pipes and energy consumption.

Description

Technical field: [0001] The invention belongs to the technical field of hydraulic transmission, and in particular relates to a control valve group of a novel hydraulic motor transmission device. Background technique: [0002] The hydraulic motor transmission device is a widely used basic part of hydraulic transmission. It is generally composed of a hydraulic motor, a hydraulic brake (or clutch), a gear reducer, etc. The hydraulic system needs to control the start and stop of the motor, forward and reverse and The rotation speed controls the brake (or clutch) of the hydraulic brake (or clutch). At present, the hydraulic brake (or clutch) control valve of the hydraulic motor transmission device is often set independently and connected by pipes, and the structure is relatively complicated. Invention content: [0003] The object of the present invention is to provide a novel hydraulic motor transmission control valve group which can be arranged near the hydraulic motor transm...
