Embodiment Construction

[0006] see figure 1 , The pure electric explosion-proof vehicle chassis system includes: 1. Vehicle frame, 2. Electric powertrain (including explosion-proof drive motor, gearbox and wet parking brake), 3. Drive shaft, 4. Drive axle (with multi-disc wet type Brake), 5. Front axle (with multi-disc wet brake and steering cylinder), 6. Front suspension, 7. Rear suspension, 8. Hydraulic system, 9. Anti-static tires.

[0007] The electric powertrain 2 is integrated by an explosion-proof driving motor, a reduction box and a wet parking brake. Connection, the rigid connection of this shell to the shell makes it form an integral structure. In addition, the drive motor is explosion-proof, and the wet parking brake is a multi-disk safety failure type, which is used for parking and emergency braking of the vehicle on a slope.

[0008] The electric powertrain 2 is placed in the middle, that is, it is arranged between the front and rear axles and installed on the frame 1 through rubber sh...

Abstract

The invention relates to a chassis system for a pure electric vehicle, which is applied to I and II types of explosion-proof environments and has an explosion-proof function. The chassis system comprises an electric power assembly, wherein the electric power assembly is integrated with an explosion-proof driving motor, a speed-reducing box and a wet type parking brake and provides power for an intelligent explosion-proof electric automobile; the speed-reducing box is used for reducing speed and increasing torsion; the wet type parking brake of a safety failure type is provided and used for parking and emergently braking the vehicle on a ramp; and the electric power assembly is placed between a front axle and a rear axle and above a vehicle frame. The chassis system for the pure electric explosion-proof vehicle comprises a single-stage main speed-reducing automobile driving axle with a multi-disc wet type service brake, so that a transmission system has high transmission efficiency and excellent explosion-proof performance. The chassis system for pure electric explosion-proof vehicle comprises an explosion-proof hydraulic system, wherein the explosion-proof hydraulic system is used for providing pressure oil according with the requirement to the multi-disc wet type service brake, the wet type parking brake and a steering system and controlling steering or braking reliably and effectively. The chassis system for pure electric explosion-proof vehicle further comprises an anti-static tyre, so that the explosion-proof performance of the whole vehicle is further improved.

Description

technical field [0001] The invention belongs to a chassis system for a pure electric explosion-proof vehicle, and is particularly suitable for explosion-proof electric trackless rubber-tyred vehicles in Class I and Class II explosion-proof environments. Background technique [0002] The application of trackless rubber-tyred vehicles in coal mine shafts has greatly improved the production capacity and transportation efficiency of shafts. Explosion-proof electric trackless rubber-tyred vehicles will gradually replace them with the advantages of zero emissions, less maintenance, low energy consumption, and low noise. Explosion-proof diesel engine trackless rubber-tyred vehicle. Although the explosion-proof electric trackless rubber-tyred vehicle has the advantages of new energy technology, there are many restrictions on the selection of the chassis. On the one hand, the drive axle of the explosion-proof engineering vehicle with wet brakes has low transmission efficiency; Axle ...
