Steering drive axle and forklift

Abstract

The invention discloses a steering drive axle and a forklift. The steering drive axle comprises a shell, a differential power mechanism, a left steering box body and a right steering box body, the shell comprises an upper box body and a lower supporting plate, and the left steering box body and the right steering box body are both arranged between the upper box body and the lower supporting platein a rotatable mode. the differential power mechanism comprises a differential assembly, a left power output half shaft and a right power output half shaft, the power output half shafts serve as powerinput of the steering box body, and a power output shaft is arranged on the steering box body; and the differential power mechanism comprises a steering oil cylinder used for driving the left steering box body and the right steering box body to rotate synchronously. The forklift comprises a front axle and a rear axle, and the front axle and/or the rear axle adopt/adopts the steering drive axle. The steering angle can reach 60 degrees, turning in a small space can be achieved, the steering structure and the driving structure are separated and do not interfere with each other or influence eachother, a vehicle provided with the axle can run on complex road conditions, large-angle steering can be achieved, turning is flexible, and turning in the small space can be achieved.

Description

technical field [0001] The invention relates to a forklift using the steering drive axle and belongs to the technical field of vehicle steering drive. Background technique [0002] Axles are mostly used on the rear axle of forklifts. Although forklifts are widely used, they have certain requirements for road conditions. Ordinary forklifts can run normally on flat roads, but they may not work normally in rainy and muddy road conditions. There are mainly two types of steering axles on the market now, one is the axle without drive, and the other is the axle with drive. The characteristic of the axle without drive is that the turning angle is about 70°, and it can also turn within a small range. However, when encountering complex road conditions such as rainy days and muddy conditions, due to the lack of power to drive the wheels, there will be problems such as slipping and getting stuck in the quagmire, resulting in failure to realize normal driving. Driving; now the common dr...

The characteristic of the axle without drive is that the turning angle is about 70°, and it can also turn in a small range. However, when encountering complex road conditions such as rainy days and muddy conditions, due to the lack of power drive of the wheels, there will be problems such as slipping and getting stuck in the quagmire, resulting in failure to realize normal driving. Driving; now the common driving axle on the market, its turning structure is to connect the half shafts on both sides through the differential, and the half shaft is connected to the wheel side shaft head through the cross shaft to realize the drive, and the steering drive mechanism drives the wheel side shaft head Turning angle, on the one hand, due to the influence of the structure of the cross shaft itself, the steering angle is limited. On the other hand, steering and power transmission must pass through the cross
