[0005] Specific implementation method

[0006] See figure 1 , The chassis system for pure electric explosion-proof vehicles includes: 1. Frame, 2. Electric power assembly (including explosion-proof drive motor, reduction box and wet parking brake), 3. Drive shaft, 4. Drive axle (with multiple wet Brakes), 5. Front axle (with multi-disc wet brakes and steering cylinders), 6. Front suspension, 7. Rear suspension, 8. Hydraulic system, 9. Anti-static tires.

[0007] The electric power assembly 2 is integrated by an explosion-proof drive motor, a reduction box, and a wet parking brake. The reduction box housing and the motor housing are connected by bolts, and the wet parking brake housing and the reduction box housing are bolted. Connection, the rigid connection of the shell and the shell makes it an integrated structure. In addition, the drive motor is an explosion-proof type, and the wet parking brake is a multi-disc safety failure type, which is used for parking and emergency bra...

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 ...
