Problems solved by technology

[0002] The existing pure electric loader travel drive system mainly has two types: one adopts the main motor plus a second-speed transmission, which is a simple and reliable technical route, but the transmission failure rate is high and maintenance is troublesome; the other adopts Dual-motor form, that is, the front and rear motors are respectively connected to the front and rear axles through the transmission shaft
This technical route sinks the motor, which is beneficial to the overall layout of the loader, but in some working conditions it will cause power waste and high cost
[0003] At present, there is a Chinese patent application publication number CN109457744A disclosing a drive control system applied to pure electric loaders, but this patent belongs to the above-mentioned first situation, and adopts the form of a main motor plus a second-speed transmission. This technical route is simple in layout, Reliable, but the gearbox has a high failure rate and troublesome maintenance

Description

technical field [0001] The invention relates to the technical field of power systems, in particular to a driving system of an assist type electric loader. Background technique [0002] The existing pure electric loader travel drive system mainly has two types: one adopts the main motor plus a second-speed transmission, which is a simple and reliable technical route, but the transmission failure rate is high and maintenance is troublesome; the other adopts In the form of dual motors, the front and rear motors are respectively connected to the front and rear axles through transmission shafts. This technical route sinks the motor, which is beneficial to the overall layout of the loader, but it will cause power waste and high cost under certain working conditions. [0003] At present, there is a Chinese patent application publication number CN109457744A disclosing a drive control system applied to pure electric loaders, but this patent belongs to the above-mentioned first situa...
