Description
Technical field
The invention belongs to the automobile-used chassis system of a kind of pure Electric Explosion-proof, be specially adapted to the anti-explosion electric railless free-wheeled vehicle under I class and the II class explosion-proof environment.
Background technology
The application of railless free-wheeled vehicle roadway in the colliery has greatly improved the productive capacity and the conveying efficiency of roadway, the anti-explosion electric railless free-wheeled vehicle then with zero-emission, maintenance less, energy consumption is low, noise is little advantage, soon progressively replace anti-explosion diesel engine railless free-wheeled vehicle.Though the anti-explosion electric railless free-wheeled vehicle has the new energy technology advantage; But; Selecting for use on the chassis to have many restrictions, is that explosion-proof band oil-immersed multi-disk brake engineering truck drive axle driving efficiency is low on the one hand, is that the higher automobile drive axle drg of driving efficiency is not explosion-proof on the other hand.Therefore, press for a automobile-used chassis of new type explosion proof that higher driving efficiency can be arranged explosion-proof, again of exploitation.The automobile-used chassis system of this pure Electric Explosion-proof, be applied in coal roadway environment early stage earlier, and more can enlarge special high-risk environment such as being used in reserve and weapon depot future based on this.
Summary of the invention
The pure electric vehicle that the present invention relates to a kind ofly to be used for I class and II class explosion-proof environment, has an explosion prevention function is used chassis system; It comprises one by the integrated EMF Electronmotive Force assembly of explosion-proof drive motor, drop-gear box and wet type Parking Brake; For explosion-proof intelligent electric automobile provides power; Realize slowing down to increase turning round through drop-gear box, and dispose the wet type Parking Brake of a fail safe type, be used for vehicle Parking and emergency brake on the ramp.Place in the said EMF Electronmotive Force assembly between the bridge of front and back, on the vehicle frame.The automobile-used chassis system of this pure Electric Explosion-proof comprises the single-stage master of the band multi-disc wet type running brake automobile drive axle that slows down, and makes driving system both have higher driving efficiency, possesses good explosion-proof performance again.The automobile-used chassis system of this pure Electric Explosion-proof comprises an explosive-proof hydraulic system, provides to multi-disc wet type running brake, wet type Parking Brake and steering swivel system to meet required pressure oil, and reliable and effectively control brake or turn to.The automobile-used chassis system of this pure Electric Explosion-proof also comprises antistatic wheel tyre, with further raising car load explosion-proof performance.
Description of drawings
Fig. 1 is the automobile-used chassis system figure of pure Electric Explosion-proof.
The practical implementation method
Referring to Fig. 1, the automobile-used chassis system of pure Electric Explosion-proof comprises: 1, vehicle frame, 2, EMF Electronmotive Force assembly (comprising explosion-proof drive motor, drop-gear box and wet type Parking Brake); 3, transmission shaft, 4, drive axle (band multi-disk wet brake), 5, propons (band multi-disk wet brake with turn to oil cylinder); 6, front suspension; 7, rear suspension, 8, hydraulic efficiency pressure system, 9, antistatic wheel tyre.
EMF Electronmotive Force assembly 2 is integrated by explosion-proof drive motor, drop-gear box and wet type Parking Brake institute; Said drop-gear box housing and electric machine casing bolt together; Said wet type Parking Brake housing and drop-gear box housing bolt together, being rigidly connected of this housing and housing makes it being integrally formed structure.And drive motor is an explosion proof type, and the wet type Parking Brake is multi-disc type fail safe type, be used for vehicle Parking and emergency brake on the ramp.
EMF Electronmotive Force assembly 2 is mid-; Promptly be arranged between the bridge of front and back, be installed on the vehicle frame 1 through rubber damper; Power is exported by explosion-proof drive motor, realize to slow down to increase through drop-gear box and turn round, again through wet type Parking Brake mouth flange be attached thereto the transmission shaft 3 that connects; With the drive axle 4 that is connected with transmission shaft 3, thereby drive wheels, make vehicle advance or retreat.
Drive axle 4 is connected with vehicle frame 1 through rear suspension 7.Drive axle 4 band multi-disc wet type running brake had both kept the slow down advantage of the higher driving efficiency of automobile drive axle of double curved surface conical gear single-stage master, had digested and assimilated the explosion-proof cutting edge technology of foreign project vehicle bridge again; Simultaneously, in order to meet national coal industry relevant criterion, said configuration multi-disc wet type running brake is a hydraulic braking spring release type, has both possessed the good explosion-proof performance of introduction of foreign technology and has been different from this.
Propons 5 is connected with vehicle frame 1 through front suspension 6.Propons 5 is non-driving steeraxle, is with the multi-disc wet type running brake and turns to oil cylinder.Saidly turn to oil cylinder to be arranged in tierod middle part and be a section of intermediate rod, this layout makes steering hardware simple, compact, efficient, and has omitted steering drag link and track arm.
Hydraulic efficiency pressure system 8 mainly is made up of hydraulic workstation, energy storage, treadle valve, hand control valve (HCV), convertible valve and hydraulic tubing etc.; Said hydraulic workstation places on the vehicle frame 1, comprises fire proof motor, gear type pump and hydraulic reservoir etc., for hydraulic efficiency pressure system provides pressure oil; Said gear type pump is built in hydraulic reservoir, and motor is then external and be connected with gear type pump is coaxial, and the two is jointly by the flange supporting that places on the hydraulic oil tank wall.Said hydraulic tubing is arranged on the device such as vehicle frame 1, drive axle 4 and propons 5, meets the hydraulic oil of system pressure demand separately for brake system transmits with steering system; Chaufeur is through controlled pedal valve, hand control valve (HCV) and convertible valve, reliably and effectively control brake or turn to.Said hydraulic efficiency pressure system 8 has been owing to adopted fire proof motor, and treadle valve, hand control valve (HCV), convertible valve and hydraulic tubing etc. are steel structure, makes whole hydraulic efficiency pressure system reach requirement of explosion proof.The explosive-proof hydraulic system also disposes energy storage, to guarantee still possess certain braking and turn to function when unpowered.
For further improving the car load explosion-proof performance, 4 wheels all dispose antistatic wheel tyre 9.
Need to prove that every corresponding change of doing according to this thinking is all within protection domain of the present invention.
