Forklift gearbox with differential lock

Abstract

The invention relates to a forklift gearbox with a differential lock, and the gearbox comprises a gearbox assembly and a reducer assembly, wherein the gearbox assembly and the reducer assembly are connected by a shaft coupler assembly for power transmission connection. The gearbox assembly and the reducer assembly are connected by a support seat assembly. The gearbox assembly includes a torque converter, an input shaft, an idler shaft, an intermediate shaft, a rear output shaft, a front output shaft and a jaw clutch, which are all disposed in the housing. The reducer assembly includes a powerinput shaft, a drive shaft, a differential mechanism, a left half shaft, a right half shaft, and a differential lock, which are all disposed in the housing. The gearbox has a differential lock and iscompact, and has a front and rear power output function, wherein front-end power output that can be switched off.

Description

technical field [0001] The invention belongs to the technical field of gearboxes, and in particular relates to a gearbox for a forklift with a differential lock. Background technique [0002] The main function of the gearbox is to adapt to the high-speed driving of the vehicle when the vehicle starts, accelerates, climbs and flat roads under various road conditions. Since the engine cannot be reversed, the forward and reverse movements of the forklift are also handled by the transmission. In addition, the gearbox can also disconnect the operation of the engine and the drive system from each other for a longer period of time. However, the existing gearboxes for forklifts are bulky and relatively simple in structure, and do not have the function of power output at the front and rear ends, so they cannot meet the needs of various working conditions. [0003] In addition, at present, the reducer assembly of the forklift gearbox is generally divided into two types. One is the r...

Problems solved by technology

However, the existing gearboxes for forklifts are bulky, relatively simple in structure, and do not have the function of power output at the front and rear ends, so they cannot meet the needs of various working conditions.

[0003] In addition, at present, the reducer assembly of the forklift gearbox is generally divided into two types. One is the reducer without a differential structure. This type of reducer is easy to damage the transmission system parts during normal use, and it is easy to turn when turning. The other is a reducer with a differential structure. Although this type of reducer has a differential, it is not equipped with a differential lock. In this way, when the differential rear axle of the forklift is on a muddy road, When one wheel spins, all the power is consumed by the spinning wheel, and the other wheels lose power

With the increasing complexity of forklift operating conditions and the improvement of forklift off-road performance requirements, the current forklift reducer assembly can no longer meet the demand, and it is urgent to develop a reducer that meets the outdoor off-road requirements of forklifts.
