Description

Technical Field

[0001] The invention relates to the technical field of mining truck driving, and in particular to a driving form of a mining truck. Background Art

[0002] In the process of economic development, energy mining is indispensable. In the process of mining resources, mining trucks are needed to transport minerals. At present, mining trucks mainly include 4×2 and 6×2 models. The driving mode is mainly rear axle drive or rear double axle drive. The driving power is a traditional fuel engine or a new energy electric motor.

[0003] However, at present, most new energy mining trucks are basically modified and manufactured based on the original oil truck platform. Due to the limitations of existing motor technology and cost control, the models driven by new energy electric motors have weak power due to factors such as insufficient power and torque, especially when climbing hills.

[0004] Therefore, the problem of insufficient power and difficulty in climbing slopes of existing new energy mining trucks should be solved. Summary of the invention

[0005] The technical problem to be solved by the present invention is to provide a driving form for a mining truck in view of the above-mentioned technical deficiencies, which solves the problem that the existing new energy mining trucks are insufficient in power and have difficulty in climbing slopes.

[0006] The technical solution adopted by the present invention is: to provide a driving form of a mining truck, including: a frame, a main motor is arranged on the frame, and the main motor is connected to a transmission shaft through a gearbox, and is characterized in that it also includes:

[0007] A parallel double-axle drive axle, arranged at the rear side of the vehicle frame, the transmission shaft is drivingly connected to the parallel double-axle drive axle, and is used to provide power to the parallel double-axle drive axle, the parallel double-axle drive axle includes a first rear drive axle and a second rear drive axle connected in parallel;

[0008] The first steering electric drive axle has a steering function and is used to provide auxiliary power for the vehicle. The first steering electric drive axle is arranged on the frame and is located in front of the parallel double-axle drive axle or in the rear of the parallel double-axle drive axle. The first steering electric drive axle includes a first steering axle and a first electric drive structure.

[0009] Further optimizing the technical solution, when the first steering electric drive axle is located at the rear side of the parallel dual-axis drive axle, it also includes:

[0010] The second steering axle is arranged on the vehicle frame and is located at the front side of the parallel dual-axle drive axle.

[0011] Further optimization of this technical solution also includes:

[0012] The second electric drive structure is arranged on the second steering axle and is configured with the second steering axle to form a second steering electric drive axle.

[0013] Further optimizing the technical solution, when the first steering electric drive axle is located in front of the parallel dual-axle drive axle, it also includes:

[0014] The third steering axle is arranged on the vehicle frame and is located in front of the first steering electric drive axle.

[0015] Further optimization of this technical solution also includes:

[0016] The third electric drive structure is arranged on the third steering axle and is constructed together with the third steering axle to form a third steering electric drive axle.

[0017] To further optimize the technical solution, the first steering axle includes:

[0021] The beneficial effects of the present invention are:

[0022] 1. Through the parallel double-axle drive axle and the first steering electric drive axle, a 6×6 all-wheel drive form is formed. Compared with the existing 4×2 and 6×2 models, it can provide stronger power. The main motor plus the gearbox transmits power to the parallel double-axle drive axle through the drive shaft. The vehicle uses the main motor to drive to provide power on flat roads. When climbing a slope, the first steering electric drive axle works at the same time to provide power, making climbing easier and solving the problem of difficulty in climbing.
