Problems solved by technology

Mining dump trucks mostly drive in one direction. During the process of unloading materials, it is necessary to turn the head of the vehicle and then return to the original road. The efficiency of vehicle transfer is low; material unloading can only be carried out in one direction, which is inconvenient for material unloading
[0003] In addition, traditional mining dump trucks rely on manual driving and require a lot of manpower, which will undoubtedly increase more labor costs for remote mining areas

Embodiment 1

[0057] The hybrid two-way driving unmanned mining dump truck chassis of the present invention, through the calculation and control of the front and rear unmanned modules 3, when driving under high-load road conditions such as climbing and potholes, the range extender 14 works at full load Together with the power battery 10-1, the two drive motors 13-1 are supplied with energy, and the driving force is large at this time; when driving under low load conditions, according to the power status of the power battery 10-1, if the power is high, the range will be increased. The power battery 10-1 is used as the main power supply object. If the power is low, the range extender 14 is the main power supply object. If the power is lower than the warning line, the range extender 14 is the power battery 10 at the same time. -1 charging; when braking downhill, the drive motor 13-1 participates in braking, and feeds the braking energy back to the power battery 10-1; while saving energy and pro...

Embodiment 2

[0060] In the hybrid two-way driving unmanned mining dump truck chassis of the present invention, the forward and reverse gears of the gearbox 13-3 are the same, so that two-way driving is realized, and the original road can be returned without turning around, and the production efficiency is improved; The first steering drive axle 13-5 and the second steering drive axle 13-7 use a steering cylinder 131 for hydraulic steering. The engine 11 is provided with an oil pump 130, and the oil pump 130 takes power from the engine 11 to drive the steering cylinder 131 to move for steering. , realizes all-wheel steering, solves the problem of difficult turning of the vehicle in a narrow space, and at the same time improves the operation efficiency and vehicle driving safety.

Embodiment 3

[0062] The hybrid bidirectional driving unmanned mining dump truck chassis of the present invention adopts an unmanned system, which reduces human resources, improves the attendance efficiency of the mining dump truck, and saves human resources.

[0063] The front and rear unmanned modules 3 specifically include a fusion perception subsystem, a control subsystem, a remote subsystem, a vehicle interaction subsystem and an execution subsystem, and the control subsystem includes an automatic driving control system and a vehicle controller. The automatic driving control system and the vehicle controller are connected in data communication, the fusion perception subsystem and the automatic driving control system are connected through a data signal line, and the remote subsystem, the vehicle interaction subsystem and the execution subsystem are all connected to the vehicle controller. connect.

[0064] The automatic driving control system mainly completes the issuance of the automat...

Abstract

The invention discloses a hybrid two-way driving unmanned mining dump truck chassis which comprises a chassis body, a dump truck hopper and a front-back unmanned driving module, the dump truck hopper is connected with the chassis body through a lifting oil cylinder, and the front-back unmanned driving module is connected with the end of the chassis body; the chassis comprises a frame, a driving system and a range extender, the range extender is composed of a generator and an engine, the range extender is connected with the end of the frame and drives the generator to work through the engine, the driving system is connected with the frame through a suspension, a hybrid power scheme is adopted, the range extender drives the generator to work through the engine, and the range extender drives the generator to work through the engine. Two groups of driving systems are adopted and are symmetrically arranged at two ends of the frame; the front and rear motors are used for driving, so that the high driving range of the vehicle is ensured while the dynamic property of the vehicle is ensured; bidirectional driving and all-wheel steering are achieved, the problem that a vehicle is difficult to turn around in a narrow space is solved, and meanwhile the operation efficiency and the vehicle driving safety are improved.

Description

technical field [0001] The invention belongs to the technical field of engineering vehicles, in particular, the invention relates to a hybrid two-way driving unmanned mining dump truck chassis. Background technique [0002] Mining dump trucks are used to transport coal or ore in mines. Most mining dump trucks drive in one direction. During the process of unloading materials, it is necessary to turn the head of the truck and then return to the original road. The efficiency of vehicle transfer is low; the material unloading can only be carried out in one direction, which is inconvenient for material unloading. [0003] In addition, traditional mining dump trucks rely on manual driving, which requires a lot of manpower, which undoubtedly increases labor costs for remote mining areas. SUMMARY OF THE INVENTION [0004] The present invention provides a hybrid two-way driving unmanned mining dump truck chassis to solve the problems existing in the above background technology. ...
