Problems solved by technology

[0004] At present, many storage vehicles still adopt the form of mechanical steering. If the steering is to save effort, the length of the steering handle needs to be large, and the operation flexibility is poor. High, and there is a certain steering action hysteresis

Embodiment Construction

[0021] Such as Figure 1 to Figure 5 As shown, an electronic steering assist system suitable for a mechanically steered forklift disclosed in the present invention includes a torque sensor 1 , a DC deceleration motor 2 , a motor controller 3 and a transmission gear 4 .

[0022] The torque sensor 1 is rigidly connected to the steering handle 5 and the steering shaft 6, the torque sensor 1 and the DC geared motor 2 are electrically connected to the motor controller 3, and the motor controller 3 controls the DC geared motor 2 to start according to the steering signal captured by the torque sensor 1. For power steering, the drive wheel 21 of the DC reduction motor 2 is connected to the transmission gear 4 on the steering shaft 6 for transmission.

[0023] Like this, the present invention has only adopted torque sensor 1, and does not need two angle sensors, through the rigid connection of torque sensor 1 and steering tiller handle 5 and steering shaft 6, both can reach the purpose...

Abstract

The invention discloses an electronic power-assisted steering system suitable for a mechanical steering forklift. The electronic power-assisted steering system comprises a torque sensor, a direct-current speed reducing motor, a motor controller and a transmission gear. The torque sensor is in rigid connection with a steering tiller and a steering shaft. The torque sensor and the direct-current speed reducing motor are electrically connected with the motor controller. The motor controller the direct-current speed reducing motor to start for power-assisted steering according to a steering signal captured through the torque sensor, and a driving wheel of the direct-current speed reducing motor is connected with the transmission gear on the steering shaft for transmission. By the adoption of the electronic power-assisted steering system, steering labor can be saved by 50% to the maximum degree, the hysteresis quality is avoided, the whole structure is compact, a motor model is smaller, and cost is low.

Description

technical field [0001] The invention relates to an electronic steering assist system suitable for a mechanically steered forklift, such as a storage vehicle. Background technique [0002] The so-called mechanical steering system refers to the rigid connection between the steering handle and the steering shaft, and the direct steering torque of the person is used to realize the steering. [0003] The so-called electronic steering system refers to the angle sensor connected to the lower end of the steering handle, which is not connected to the steering shaft; the steering shaft is connected to the steering motor through a gear pair, and the output end of the steering motor (or steering shaft gear) is equipped with an angle sensor. When the tiller turns, the angle sensor captures the angle signal and converts it into an electrical signal, which is sent to the steering motor controller to control the rotation direction and time period of the steering motor to realize full electr...
