Soft airway structure of electric driving mining dump vehicle for connecting rear axle housing and motor

Abstract

The invention discloses a soft airway structure of an electric driving mining dump vehicle for connecting a rear axle housing and a motor and belongs to the technical field of airway structures. An air source of the rear axle housing is connected with an airway port of a wheel side motor through matching of a soft airway body and a guide rail flange of a guide rail structure mode. The soft airway structure has the advantages that the guide rail flange is of a guide rail structure, and bolt fixing connection only needs to be performed on one side of the soft airway body, so that installation and detaching of the axle housing limited in space can be achieved easily, and maintenance is convenient; the soft airway body adopts a soft connection mode, so that under the circumference that an airway port of the wheel side assembly and the airway port of the rear axle housing are not aligned with each other or cannot be aligned with each other due to manufacture and assembling errors, connection can be achieved. Tightness can be enhanced by combing with a U-shaped limiting groove of the guide rail flange and the limiting plate, the sealing effect is good, further the radiating effect is improved, and stable and reliable support can be provided for the electric driving dump vehicle.

Description

technical field [0001] The invention relates to a soft air duct structure for connecting a rear axle housing and a motor of an electric drive mining dump truck, and belongs to the technical field of air duct structures. Background technique [0002] The driving motor of the electric wheel mining dump truck releases a large amount of heat during operation. If it cannot be effectively dissipated, the temperature of the driving motor will increase, resulting in the burning of the motor. At the same time, the brake will also generate heat when it is working. If it cannot dissipate heat effectively, it will also reduce the braking efficiency and affect the safety of the vehicle. Therefore, a forced ventilation system is installed in the electric wheel mining dump truck to maintain the temperature of the motor and brake within the allowable range. As the key structure of the ventilation system, the air duct structure connecting the air source of the rear axle housing and the moto...
