Abstract

The invention discloses a test rack system for a four-wheel-drive bridge assembly. The test rack system for the four-wheel-drive bridge assembly is used for testing an electric new energy automobile, the electric new energy automobile is controlled by a central control system to operate and consists of an electric system and a control system, the electric system consists of a power measuring device, a driving system and a power supply system, the driving system is connected with the power measuring device, and the power supply system is connected with the driving system; and the control system consists of a torque sensor, a real-time system, a data collection device and an upper computer. The structure can complete test items which are completed by a traditional two-wheel-drive rack and also has the functions such as free distribution of power between shafts and free distribution and simulation of power between wheels, the system is directly connected with the central control system of the automobile through a computer, data collection and control can be carried out by using functions of the automobile, the production cost of enterprises is saved, and simultaneously, the purchase cost of users is reduced.

Description

technical field [0001] The invention belongs to an automobile drive test device, in particular to a four-wheel drive bridge assembly test bench system. Background technique [0002] New energy vehicles refer to the use of unconventional vehicle fuels as power sources (or the use of conventional vehicle fuels and new vehicle power devices), and the comprehensive vehicle power control and advanced technology in driving, the formation of advanced technical principles, with Automobiles with new technology and new structure. Electric VehiclesBlade Electric Vehicles (BEV) 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. . The central control system of the new energy vehicle can control the work of the car and implement various information during the monitoring work; for the existing fo...
