Embodiment Construction

[0034] In order to understand the technical content of the present invention more clearly, the following examples are given in detail. It should be understood that the examples are only used to illustrate the present invention, not to limit the present invention.

[0035] figure 1 is a system block diagram of the hybrid powertrain according to the embodiment of the present invention. Heavy-duty vehicles (not shown) such as city buses mostly adopt the rear-mounted rear-drive type. The hybrid power assembly 1 is longitudinally arranged behind the driving axle 5, and transmits power to the driving axle 5 and wheels 7 through the transmission shaft 3 to drive the vehicle.

[0036] refer to figure 1 , the hybrid powertrain 1 includes an engine 2 , a first air compressor 21 installed on the engine 2 , and a first power steering oil pump 22 installed at the rear of the first air compressor 21 . The first air compressor 21 is driven by the engine 2; the rotor (not shown) of the fir...

Abstract

The invention provides a series-parallel combined type hybrid power assembly (1), which comprises an engine (2), a first air compressor (21), a first power-assisted steering oil pump (22), a first motor (4), a first motor controller (8), a main clutch (20), a second motor (6), a second motor controller (10), a second air compressor (61), a second power-assisted steering oil pump (62), an air condition compressor (63), a first electromagnetic clutch (24), a second electromagnetic clutch (26), a third electromagnetic clutch (27), a fourth electromagnetic clutch (28), a first belt wheel train (23), a second belt wheel train (25) and an electric power storage device (12). The engine (2) comprises a starter (201), the first electromagnetic clutch (24) controls working conditions of the second motor (6), the second electromagnetic clutch (26) controls working conditions of the second air compressor (61), the third electromagnetic clutch (27) controls working conditions of the second power-assisted steering oil pump (62), and the fourth electromagnetic clutch (28) controls working conditions of the air condition compressor (63).

Description

technical field [0001] The invention relates to a series hybrid power assembly, in particular to a series hybrid power assembly with relatively high fuel economy and emission performance under actual operating conditions. Background technique [0002] In recent years, heavy-duty vehicles such as city buses with hybrid powertrains have been increasingly used. As one of the important responses to energy and environmental crises, hybrid vehicles have better power performance, fuel economy and emission performance, which can not only significantly reduce operating costs, but also meet increasingly stringent emission regulations. [0003] A hybrid powertrain configured on a heavy-duty vehicle mainly used as a production tool must have high fuel economy, in particular, have a significant fuel-saving effect under actual operating conditions, so as to reduce the initial cost of vehicle purchase ( including the payback period of the motor system and battery system). When the cost r...
