Embodiment Construction

[0035] The present invention will be specifically introduced below in conjunction with the accompanying drawings and specific embodiments.

[0036] like Figure 1 to Figure 7 As shown, 1. A new energy vehicle chassis load test device 100, comprising: a slope simulation test device 10, a load-bearing simulation test device 20 and a motor power detection device 30.

[0037] The slope simulation test device 10 simulates the driving conditions of the new energy vehicle 200 on different slopes by adjusting the posture of the new energy vehicle chassis 201 .

[0038] The load-bearing simulation test device 20 adjusts the pressure on different areas of the new energy vehicle chassis 201 to simulate the working conditions when the new energy vehicle 200 bears different loads as a whole and different areas bear deflected loads.

[0039] The motor power detection device 30 is used to detect the power of the motor 203 of the new energy vehicle 200 in real time. The motor power detectio...

Abstract

The invention discloses a new energy vehicle chassis load testing device. A lifting motor drives a chain winding wheel to rotate. A supporting frame is connected with a top frame and a bottom movablebracket. One end of a chain is wound to the chain winding wheel, and the other end of the chain bypasses a fixing suspension wheel to be fixed to the bottom movable bracket. The bottom movable bracketis rotatably connected to a bottom fixing bracket. A load-bearing simulation testing device includes a pressure cylinder fixing frame, pressure cylinders and pressure heads. The pressure cylinder fixing frame is fixed to the top frame. The pressure cylinders are fixed to the pressure cylinder fixing frame. The pressure cylinder drives the pressure heads to move. The number of pressure cylinders is six. The pressure cylinders exert different forces on the pressure heads to adjust the pressure on the chassis of a new energy vehicle. The six pressure heads correspond to the left front, right front, left middle, right middle, left rear and right rear portions of the chassis of the new energy vehicle respectively. The new energy vehicle chassis load testing device disclosed in the invention can simulate complex operating conditions and has high test reliability.

Description

technical field [0001] The invention relates to a new energy vehicle chassis load testing device. Background technique [0002] A new energy vehicle is a vehicle that uses a single battery as the energy storage power source. It uses the battery as the energy storage power source, and supplies electric energy to the motor through the battery to drive the motor to run, thereby driving the car. [0003] New energy vehicles use electricity as power, avoiding the exhaust gas pollution caused by gasoline as power. Energy is saved, and environmental pollution is greatly reduced. [0004] New energy vehicles are powered by batteries. If the new energy vehicles cannot be systematically tested, it may be extremely dangerous during use. For example, the battery burns or even explodes. [0005] The traditional load test device for new energy vehicle chassis cannot satisfy the simulation of complex operating conditions and complex road conditions. Contents of the invention [0006]...
