Abstract

The invention discloses an experimental device and a method for testing the performances of a tandem type hydraulic hybrid power vehicle, which belong to the experimental devices and methods for hybrid power. An engine, a constant-pressure variable pump, a central controller, a first hydraulic pump motor, a second hydraulic pump motor, a first dynamometer, a second dynamometer, a first inertial flywheel set and a second flywheel set of the device and the method are connected in a tandem way; all performances of the vehicle with different configuration ways are simulated in an actual working condition; the real running working condition of a hybrid power car is simulated through the loading and the measurement of the first dynamometer and the second dynamometer; an electric machine drives a constant delivery pump to supply a control oil source to the hydraulic pump motors; a stable control oil source is supplied to the hydraulic pump motors through adjusting the highest overflow pressure of a first overflow valve; and simultaneously, the central controller carries out coordination control on the engine, the hydraulic pump motors and the dynamometers by combining the energy storage state of an energy accumulator and measures relevant data to complete an experiment. The experimental device and the method have the advantages of convenience in operation and high integrated level.

Description

technical field [0001] The invention relates to a hybrid test device and method, in particular to a test device and method for performance testing of a serial hydraulic hybrid vehicle. Background technique [0002] With the rapid development of industrial technology worldwide, the problems of energy shortage and environmental pollution are becoming more and more serious. Hybrid technology is considered to be one of the effective solutions to solve the energy crisis and environmental pollution problems. Compared with electric hybrid technology, hydraulic hybrid power has the characteristics of high power density, which is very suitable for the traveling devices of medium and heavy urban buses, military vehicles and construction machinery. According to the connection mode of the power system, hydraulic hybrid vehicles can be divided into serial hydrostatic transmission vehicles and parallel hydrostatic transmission vehicles. Parallel hydrostatic transmission vehicles use the...
