Description
Technical Field
The invention relates to the technical field of off-highway dump trucks, in particular to an integrated modularized dump truck suspension module, a driving module and a dump truck applying the same.
Background
The off-road (mining) electric wheel dump truck (hereinafter referred to as dump truck or vehicle) is a heavy vehicle used for completing the tasks of rock earthwork stripping and ore transportation in surface mines, and has the working characteristics of short transportation distance, load bearing capacity, high appearance and strong power, and since 1963, the loading quality is developed to 360 tons at present through continuous function perfection, new technology updating and new material and new process, so that a plurality of series products are formed, and the off-road (mining) electric wheel dump truck becomes an ideal transportation tool for surface mines and large hydraulic construction projects with annual mining quantities of more than ten million tons. The conventional dumper and the electric dumper improved on the basis have the advantages that the frame structure, the steering mechanism, the suspension system and the like are designed according to the conventional power device, the structure is complex, the occupied space is large, the design of the whole dumper is not facilitated, and the structure is simplified.
The suspension system is a general term for a force transmission mechanism for elastic connection between a vehicle frame and an axle, i.e. a vehicle running gear (including but not limited to wheel related parts such as a wheel hub, a wheel rim, a tire, etc.), and is one of the most important assemblies of an electric wheel vehicle. Rim structures in vehicle traveling devices are common, such as chinese patent documents: CN 212949991U discloses an engineering tire specially used for electric wheel dump trucks, and a rim structure suitable for matching with the tire: the rim comprises a rim body, a seat ring, a retainer ring, a lock ring and an air nozzle; the rim body is used for assembling and supporting an engineering tire; the seat ring is a tire axial supporting component detachably connected with the rim body; the retainer ring is a wheel flange detachably connected with the wheel rim body and has the function of locking the ring; the locking ring is an elastic ring which is used for locking the retainer ring and/or the seat ring and is located in a locking ring groove. The hydro-pneumatic suspension system has good nonlinear rigidity and damping characteristics, so that the smoothness of the vehicle can be greatly improved, the comfort of a driver is improved, the damage degree of vehicle parts can be reduced, the service life of the vehicle is prolonged, and the hydro-pneumatic suspension system is widely applied to mining dump trucks. The front axle structure of the mining dump truck can be generally divided into three types: the suspension comprises an integral suspension, a longitudinal single swing arm break type (commonly called an A-type frame) independent suspension and a candle type independent suspension. The suspension forms mainly include an oil gas suspension, a rubber suspension and a silicone oil suspension. The integrated front axle is mainly of a MARK-36 model of Unit-Rig company, is connected with a frame through longitudinal double swing arms at two sides of the frame and a transverse single swing arm at the right side, and only bears axial force by a left suspension and a right suspension. The R170 of Euclid company uses a longitudinal single swing arm breakaway front axle, where the left and right suspensions can move independently and also only bear axial forces. 630E of Dresser company and SF3IXX series of Hunan Tan electric machine factory adopt a candle type independent suspension system, left and right suspensions can independently move, but the stress is complex, and the vertical load, the transverse lateral deviation force and the like of the longitudinal running resistance of the whole front axle are borne by the left and right hydro-pneumatic suspensions. The integral type and longitudinal single-swing-arm disconnected front axle has the advantages of complex structure, large unsprung mass, high gravity center position of the whole automobile, simple stress of the suspension and long service life. The candle type independent suspension is simple in structure, the space in a gantry beam of a frame is large, the position of an engine assembly (comprising a generator, an exciter, a ventilator and the like) can be lowered and moved forwards, the gravity center height of the whole vehicle is lowered, the improvement of the operation stability of the vehicle is facilitated, but the stress of a suspension system is complex, and due to the effect of a kingpin inclination angle, the front wheel span can change along with the up-and-down movement of a front oil-gas suspension, so that the transverse sliding of left and right tires is caused, the abrasion among the tires, a front oil-gas suspension rod cylinder and a cylinder barrel is increased, and the service life of the tires and the front oil-gas suspension is also influenced.
The electric wheel dumper is a mining dumper directly driven by a hub motor, and the traditional mechanisms such as a clutch, a transmission shaft, a main speed reducer, a differential mechanism and the like are replaced by electric transmission, so that the structure of the dumper is greatly simplified. The electric drive dumper can be divided into an electric axle dumper and an electric wheel dumper according to the arrangement position of a motor of the electric drive dumper. The electric axle self-dumping truck is characterized in that an electric motor is arranged in a drive axle housing, 2 electric motors drive wheels at two sides through a reduction gear half shaft and a wheel side reducer respectively, and the structure of a drive axle is similar to that of a mechanical transmission self-dumping truck; the electric wheel dumper is characterized in that a motor is directly arranged in a wheel hub and is combined with a transmission system, a brake and a wheel reduction gear into a whole, and a hub motor is designed by integrating a power system, a transmission system and a brake system of a vehicle. The electric transmission is a transmission mode that an engine directly drives a generator, the electricity generated by the generator is directly supplied to a motor, and electric energy is transmitted to a driving motor combined with a driving wheel hub reducer through a cable to drive wheels to rotate. In the early development of electric wheel technology, a direct-current motor driving system is generally adopted, and the system has the characteristics of low rotating speed and high torque and has higher transmission efficiency. However, with the development of technology, compared with an alternating current motor, the direct current motor has larger volume and weight, larger noise, serious electromagnetic interference and softer mechanical property. The alternating current motor has the advantages of small volume, light weight, simple structure, low cost, small maintenance workload and the like, which cannot be realized by the direct current motor. Electric drive systems are driven from dc to ac motors, driving being a necessary trend. The alternating current motor with high efficiency, energy conservation and protection level is the best choice for the characteristics of small transportation distance of the strip mine, large line gradient, low driving speed, much dust in transportation environment and the like. With the continuous progress of the technology, the direct current motor and the alternating current motor are both in interest and harm avoidance, and when the direct current motor is applied to the field of the dump truck, the volume of the direct current motor is reduced as much as possible, so that the motor can be more closely combined with wheels, the structure of each part of the truck body is simplified, and the working efficiency is improved.
