Electric forklift based on high-voltage technology

Abstract

The invention discloses an electric forklift based on a high-voltage technology. The electric forklift comprises a walking motor and an oil pump motor, and further comprises a high-voltage system which is respectively connected with the walking motor and the oil pump motor and is used for supplying high-voltage electricity to the walking motor and the oil pump motor; and a water-cooling heat dissipation system in which a water-cooling loop passes through the high-voltage system, the walking motor and the oil pump motor so as to dissipate heat of the high-voltage system, the walking motor and the oil pump motor. The high-voltage system is introduced into the electric forklift, more electric quantity and smaller current are provided for the electric forklift, the cruising ability of the electric forklift is improved, the heat productivity of electrical elements of the electric forklift is reduced, the service life of the electrical elements is prolonged, and the performance of the wholeforklift is improved. The water-cooling heat dissipation system is introduced into the electric forklift, so that the heat dissipation effect is improved, the walking motor and the oil pump motor havea good heat dissipation effect, the performance specifications of working components such as the walking motor and the oil pump motor are improved, and the working performance of the whole electric forklift is improved.

Description

technical field [0001] The present invention relates to the field of forklift technology, more specifically, relates to an electric forklift based on high voltage technology. Background technique [0002] Current electric forklifts use low-voltage power supply systems as power sources. For example, electric forklifts below 10 tons mostly use low-voltage systems below 96V. [0003] With the development of social economy and technology and the improvement of environmental protection requirements, it has become a development trend for electric forklifts to replace internal combustion forklifts, which puts forward higher requirements for the performance of electric forklifts. The improvement of the performance of the electric forklift has great constraints, which makes it more and more difficult to improve the performance of the electric forklift. [0004] Therefore, how to overcome the restriction of the low-voltage system power supply on the performance of the electric forkli...
