Embodiment 1

[0052] This embodiment provides an electric vehicle chassis assembly, such as figure 1 As shown, it includes: frame body 1, front axle 2, rear axle 3, first connecting rod 4 and second connecting rod 5; one end of said first connecting rod 4 is hinged with front axle 2, and the other end is hinged with vehicle frame One end of the second connecting rod 5 is hinged with the front axle 2, and the other end is hinged with the vehicle frame; when the vehicle chassis is facing a roll road, when the center of gravity of the vehicle body drives the vehicle frame to move relative to the vehicle wheel axle, through The setting of the first connecting rod 4 and the second connecting rod 5 can realize the pulling force of the front axle 2 or the rear axle 3 on the vehicle frame, provide a force in the horizontal direction for the vehicle frame, reduce the force on the spring, and play a role in the spring. The function of protection makes the electric vehicle chassis assembly have more e...

Embodiment 2

[0067] The mine electric vehicle provided in this embodiment includes the electric vehicle chassis assembly described in Embodiment 1; the mine electric vehicle also has a battery pack, and the battery pack is installed on the main beam of the frame body 1 through a shock-absorbing pad The battery pack supplies power to the drive motor 6 through the battery high-voltage box and the high-voltage distribution box, and manages the output of the battery through the BMS management system. The battery is equipped with an independent water-cooling unit for heat dissipation, and the battery water-cooling unit is arranged at the rear of the vehicle.

[0068] The cab of the mining tram adopts integrated molding technology. The body adopts square steel frame and iron plate skin structure. The interior of the cab is made of black soft interior. Each rear door adopts a fully enclosed structure.

[0069] The whole vehicle is powered by a new energy battery pack plus a travel motor and a hy...

Abstract

The invention provides an electric vehicle chassis assembly and a mining electric vehicle and belongs to the technical field of mine cars. The electric vehicle chassis assembly comprises a frame body,a front axle, a rear axle, a first connecting rod and a second connecting rod; wherein one end of the first connecting rod is hinged with the front axle, and the other end is hinged with the frame; one end of the second connecting rod is hinged with the rear axle, and the other end is hinged with the frame; according to the electric vehicle chassis assembly, when the vehicle chassis faces a laterally inclined road surface and the gravity center of the vehicle body drives the vehicle frame to translate relative to the vehicle wheel axle, through the arrangement of the first connecting rod andthe second connecting rod, the tension of the front axle or the rear axle to the vehicle frame can be achieved, a horizontal force is provided for the vehicle frame, and the force to the spring is reduced; and the springs are protected so that the chassis assembly of the electric vehicle has more excellent anti-roll capacity.

Description

technical field [0001] The invention relates to the technical field of mining vehicles, in particular to an electric vehicle chassis assembly and an electric vehicle for mining. Background technique [0002] At present, most underground mining vehicles use diesel engines as the power source. However, due to the small underground working space and poor air circulation, the diesel engine exhaust emissions are high and the noise is loud, causing serious environmental pollution in underground operations and affecting the physical and mental health of underground workers. Health, planted a certain security risks. At the same time, the working efficiency of the diesel engine is also greatly affected by the low-oxygen environment in the well, which is prone to problems such as insufficient power, increased fuel consumption, and excessive emissions. In addition, the transmission system of underground mining vehicles mostly adopts mechanical or hydraulic mechanical transmission. In ...
