The invention relates to a double-motor driving device with a parking brake of an electric forklift. The double-motor driving device comprises a speed reducer and driving motors, wherein the speed reducer comprises an output shaft, a left input shaft and a right input shaft which are parallel to each other. An output gear is arranged on the output shaft, a left input gear is arranged on the left input shaft, a right input gear is arranged on the right input shaft, and the left input gear and the right input gear are both meshed with the output gear constantly. The extending-out end of the output shaft is connected with the input shaft of the speed reducer through a transmission shaft, the extending-out end of the left input shaft is provided with a braking drum and the parking brake respectively, the other end of the left input shaft is connected with a left driving motor through a spline, the right input shaft is connected with a right driving motor through a spline, and the left driving motor and the right driving motor are arranged side by side. According to the double-motor driving device, two small-power motors are utilized to output moment in a coupling mode, therefore, needs of input power of the finished vehicle are met, the layout is utilized reasonably, and large brake torque required by the large-tonnage forklift is achieved by means of the attached parking brake.
Description
technical field [0001] The invention belongs to the technical field of forklifts, in particular to a drive device for an electric counterbalanced forklift. Background technique [0002] At present, battery counterbalanced forklifts generally have two forms of single-motor drive and dual-motor drive. Single motor drive system ( image 3 shown) is generally made up of drive motor 19, reduction box assembly 20 and drive axle assembly 21. The driving motor 19 of the drive axle assembly is directly connected with the reduction box assembly 20, and the torque is transmitted to the left and right driving wheels of the drive axle assembly 21 through one or two stages of deceleration. The double-motor drive system is that two drive motors are directly connected with the right wheel side reducer 25 and the left wheel side reducer 22 respectively, and drive two drive wheels respectively. According to the matching principle of motor and electric control, the greater the power of the m...
