Embodiment Construction

[0031] The present invention will be further described below through specific embodiments.

[0032] refer to Figure 1 to Figure 8 , an electric steering structure of a counterbalanced forklift, including a steering bridge, a steering motor 70, a reduction mechanism 40 and other structures. The steering bridge body is used as an actuator for steering action, and it is provided with a housing 10, a tie rod 20, a connecting rod 31, a steering knuckle 30, and the like. The main body of the shell 10 is made by one-time casting method. The tie rod 20 is located in the casing 10 , and the steering knuckle 30 is connected with the tie rod 20 .

[0033] Specifically, it includes two steering knuckles 30 which are respectively connected to the two ends of the tie rod 20 , and the steering knuckle 30 and the tie rod 20 are rotatably connected through a connecting rod 31 . The steering knuckle 30 adopts a conventional steering connection structure, which is driven by a slider rocker, ...

Abstract

An electric steering structure of a counterbalance forklift truck comprises a steering axle body, the steering axle body is provided with a shell, a transverse pull rod, a connecting rod and a steering knuckle, the transverse pull rod is located in the shell, and the steering knuckle is connected with the transverse pull rod; the structure further comprises a steering motor and a speed reducing mechanism. The output end of the steering motor is connected with the input end of the speed reducing mechanism; the speed reducing mechanism is arranged in the shell and is provided with an output gear; a rack is arranged on the transverse pull rod and meshed with the output gear. The structure is suitable for the four-fulcrum counterbalance forklift truck, and is compact in structure, high in space utilization rate and low in cost.

Description

technical field [0001] The invention relates to the field of forklifts, in particular to an electric steering structure of a counterbalanced forklift. Background technique [0002] At present, the steering mechanism of forklifts includes hydraulic power steering structure and electric power steering structure. For the hydraulic steering mechanism, the pump motor is used to provide power to the hydraulic pump. The lever mechanism acts to realize wheel steering. The sensitivity and steering efficiency of this structure are relatively low, the maintenance cost is high, and there is a potential safety hazard of hydraulic oil leaking and polluting the environment. [0003] For the electric power steering mechanism, see ZL200620103920.7, ZL201520938206.9 and ZL201620559438.8 all disclose a vertical steering drive device, the drive motor and the steering motor are mounted on the connection plate, and the drive motor transmits power to the wheels through bevel gears . In these sc...
