Abstract

The invention relates to an electrified steering vertical driving device. The electrified steering vertical driving device comprises a power assembly, a reducing mechanism and a steering mechanism. The power assembly comprises a driving motor and a steering motor, the driving motor is arranged on a connection disc, and the steering motor is arranged on a connection plate fixedly connected with the connection disc. The reducing mechanism comprises a shell body, an input end and an output end; the shell body is formed by connecting an upper shell body and a lower shell body; and the top surface of the upper shell body is horizontally provided with a slewing bearing, and the connection disc is fixedly connected to the slewing bearing. A motor shaft of the driving motor stretches into the upper shell body and is connected with the input end, and the output end is transversely located at the bottom end of the shell body. The steering mechanism comprises a driven steering gear and a driving steering gear; the driven steering gear is arranged on the outer circle of the slewing bearing and fixedly connected to the upper shell body; and the driving steering gear is arranged on the motor shaft of the steering motor and in correspondence engagement with the driven steering gear. According to the electrified steering vertical driving device, the installing precision requirement is low, steering is flexible, and a side gap of a spiral bevel gear is convenient to adjust.

Description

technical field [0001] The invention belongs to the technical field of forklift driving, and in particular relates to a vertical driving device for electrified steering. Background technique [0002] At present, the seat type battery reach truck generally adopts a vertical drive device, which is generally composed of a drive motor assembly, a gearbox assembly and a drive wheel assembly. The drive motor assembly is directly connected to the reduction box assembly, and the torque is transmitted to the drive wheel assembly through two-stage or three-stage reduction. Due to the limitation of the space size of the vehicle and technical problems, the entire driving device is designed as a side cover type to ensure that the driving device has the smallest turning radius when it rotates, but there are the following defects: (1). Processed parts, the tailstock of the whole vehicle is a welded part, and the tailstock of the whole vehicle needs to be reprocessed after welding to conne...
