Abstract

The invention relates to a hydrodynamic transmission used for a hydrodynamic forklift and provided with a pump mechanism. A lubrication pump transmission shaft is arranged on one side of the upper part of a transmission body, a lubrication pump is arranged at an outward extending end of the lubrication pump transmission shaft, and a first lubrication pump transmission gear is arranged on the lubrication pump transmission shaft; a hollow working pump transmission shaft tube is arranged on the other side of the upper part, a forward gear clutch and a forward gear of a second lubrication pump transmission gear are sequentially fixed on one side of the working pump transmission shaft tube, the forward gear clutch includes a forward gear clutch gear, and an oil supply pump and a hydrodynamic torque converter are arranged on the other side; a working pump transmission shaft is arranged in the working pump transmission shaft tube, and the outer end part of the working pump transmission shaft is connected with a working pump; a backward gear clutch shaft is arranged below the working pump transmission shaft tube, a backward gear clutch and a backward gear are sequentially arranged on the backward gear clutch shaft, and a clutch gear is arranged on a casing of the backward gear clutch; and a transmission shaft is arranged below the lubrication pump transmission shaft, and an output gear is arranged on the transmission shaft. The hydrodynamic transmission has two power output ports, and is provided with the working pump and the lubrication pump at the same time, thereby facilitating an entire vehicle matched wet-type brake drive axle.

Description

technical field [0001] The invention belongs to the technical field of forklift transmissions, in particular to transmissions for 2-3.5t hydraulic forklifts. Background technique [0002] At present, domestic 2-3.5t hydraulic forklifts use the engine to directly pull the working pump or the engine itself directly with the working pump. The hydraulic transmission outputs the power from the combined work of the engine and the hydraulic torque converter to the The drive axle, the hydraulic transmission and the drive axle are rigidly connected by bolts. This structure mainly has the following defects: 1. The hydraulic transmission itself does not have a working pump, and the engine directly pulls the pump or the engine itself directly carries the pump. Due to the large vibration when the engine is starting and idling, the pump is unstable and has a short life, and the cost is high due to the addition of a transition connection device, and installation and maintenance are difficu...
