Drive system for hybrid power automobile air conditioner compressor and hydraulic pump

Abstract

The invention discloses an air-conditioner compressor of hybrid vehicle and a hydraulic pump driving system; the air-conditioner compressor includes an engine and an electric motor, wherein, the engine respectively drives the air-conditioner compressor and a hydraulic pump by a clutch I and a clutch II, and the electric motor respectively drives the air-conditioner compressor and the hydraulic pump by a clutch III and a clutch IV; the air-conditioner compressor and the hydraulic pump are respectively driven by the engine and the electric motor through the clutches, and a transmission system is relatively independent, so that the problem of driving the air-conditioner compressor and the hydraulic pump when the engine stops; when in driving, mechanical joint between the engine and the electric motor can be cut off, thus eliminating the mechanical load of the electric motor to the engine, and avoiding the interference caused by that the engine and the electric motor drive the air-conditioner compressor and the hydraulic pump at the same time; therefore, the problems of low energy conversion rate and high energy dissipation which are brought by the air-conditioner compressor and the hydraulic pump are separately driven by the electric motor are avoided, and the aim of energy-saving and emission-reduction is achieved.

Description

technical field [0001] The invention relates to a driving system of an auxiliary equipment of an automobile, in particular to a driving system of an air conditioner compressor and a hydraulic pump of a hybrid electric vehicle. Background technique [0002] Automobile air conditioning and hydraulic power assist or braking systems are indispensable devices for automobiles. The traditional engine-powered vehicle uses the engine to provide the power source, and transmits the power to the car air conditioner and hydraulic pump through the transmission system to complete the corresponding functions, which not only increases the power consumption of the engine, but also increases the pollution to the environment. [0003] With the increasing pressure of energy depletion and environmental protection, hybrid electric vehicles have appeared. Hybrid electric vehicles use fuel-driven and electric-driven driving methods, and coordinate the two driving methods through reasonable control s...

Problems solved by technology

However, it will inevitably cause difficulties in arranging transmission equipment in a limited space structure and a relative increase in cost, resulting in difficulties in installation and maintenance; moreover, the transmission process will cause interference and drive additional loads to run, which will inevitably result in a reduction in energy conversion efficiency. , which is not conducive to the realization of the energy-saving goal of hybrid electric vehicles

[0006] Therefore, need a kind of hybrid electric vehicle air-conditioning compressor and hydraulic pump drive system, can avoid engine and electric motor to the interference that produces when driving air-conditioning compressor and hydraulic pump, can solve pure electric working condition (engine stoppage) in hybrid electric vehicle ) to drive the hydraulic pump and air-conditioning compressor, avoiding the problems of low energy conversion rate and large energy loss caused by the hydraulic pump and air-conditioning compressor driven by the motor alone, and achieving the purpose of energy saving
