Abstract
The invention discloses an engine crank pulley system of a mild hybrid vehicle, comprising an electrical engine having double functions of motor and generator, an engine crank pulley, an accessory pulley and an air-conditioning compressor pulley; the parts are connected by the winding belts; the engine crank pulley is connected with an engine crank through an electromagnetic clutch. The electrical engine in the system has multiple functions, realizes multiple purposes, effectively reduces the number of the electrical engines, and reduces the weight of the vehicle. The engine drives the accessories to work according to the structure of general vehicles after being started, without developing electro hydraulic or electronic steering system or components and parts, without new test certification, thereby shortening the on-production time, reducing the development expense and saving the production cost.
Description
Technical field
The present invention relates to a kind of belt pulley system of engine crankshaft, particularly a kind of belt pulley system of engine crankshaft of the automobile that adopts the BSG technology.
Background technology
Along with the worsening shortages of the energy and increasing the weight of day by day of environmental pollution, numerous car production producer all begins to research and develop energetically new-energy automobile.In many new-energy automobile solutions, obtained on a plurality of at home and abroad vehicles of the technical solution of mild hybrid electric vehicle using widely.In the present slight hybrid vehicle, adopt BSG mostly, it is the integrated scheme of starter motor-electrical generator of belt drive, starter motor-electrical generator is connected with engine crankshaft by belt in this scheme, and rely on the tensioning train to adjust the direction of transfer of belt, use the belt train starter motor-electrical generator of this structure to rotate with the rotation of engine crankshaft, starter motor-electrical generator can only play the effect of start the engine and generating and can not do him in addition and use, and the energy-saving effect that the driving engine start and stop bring often is difficult to keep out motor, battery, the negative interaction that controller weight increases.Therefore in the light hybrid car, how to realize motor loss of weight, integrated and with problem such as former car accessories compatibility be a problem that needs research especially.
Summary of the invention
At above-mentioned the deficiencies in the prior art, the technical problem to be solved in the present invention provides a kind of belt pulley system of new structure, starter motor-electrical generator not only can play the effect of starter motor and generating in this belt pulley system, and can drive other accessory system, play the technique effect of a tractor serves several purposes, thereby the number of motors on the minimizing automobile alleviates vehicle weight, reaches energy-conservation effect.
For solving the problems of the technologies described above, the present invention adopts following technical scheme:
A kind of crankshaft belt pulley system of engine of mild hybrid electric vehicle comprises: one has the motor of electrical motor and electrical generator dual-use function; One has the driving engine of bent axle; One engine crankshaft belt pulley, described engine crankshaft belt pulley is connected with engine crankshaft by a power-transfer clutch; One accessory belt pulley; One air-conditioning compressor belt pulley, described air-conditioning compressor belt pulley is connected with air-conditioning compressor by a magnetic clutch; Described motor, engine crankshaft belt pulley, accessory belt pulley and air-conditioning compressor belt pulley center on by belt and are connected.Based on above-mentioned major technique feature, described accessory belt pulley is connected with vacuum automobile pump, power steering pump with intergral reservoir.
Based on above-mentioned major technique feature, described accessory belt pulley, vacuum automobile pump and power steering pump with intergral reservoir are coaxial the connection.
Based on above-mentioned major technique feature, described power-transfer clutch is a magnetic clutch.
Based on above-mentioned major technique feature, described magnetic clutch is a direct current dry type magnetic clutch.
The present invention has following beneficial effect: engine crankshaft belt pulley in this invention, when the needs start the engine or when charging the battery with the magnetic clutch adhesive, this moment, motor was connected with engine crankshaft, and motor comes start the engine or driving engine to drive motor rotation generating as starter motor.When not needing start the engine or charging the battery, magnetic clutch is separated, driven by motor accessory belt pulley work this moment, therefore motor has multi-functional, a tractor serves several purposes in this engine crankshaft train, actv. has reduced the quantity of motor on the automobile, has alleviated the weight of automobile.Still can drive annex work by the structure of general automobile behind the engine starting, not need electric liquid newly developed or electric steering system or components and parts, not need to carry out new test authentication, thereby production time is shortened, development cost reduce, and save production cost.
Description of drawings
Fig. 1 is the structural representation of the belt pulley system of the embodiment of the invention.
Fig. 2 is embodiment of the invention engine crankshaft and engine crankshaft belt pulley connection structure scheme drawing.
Fig. 3 is embodiment of the invention accessory belt pulley and vacuum pump and power steering pump with intergral reservoir scheme of installation.
The specific embodiment
Engage accompanying drawing below, embodiments of the invention described in detail:
As shown in Figure 1, 2, as one embodiment of the present of invention, the crankshaft belt pulley system of engine of this mild hybrid electric vehicle comprises that one has motor 1, engine crankshaft belt pulley 2, accessory belt pulley 3 and the air-conditioning compressor belt pulley 4 of electrical motor and electrical generator dual-use function, engine crankshaft belt pulley 2 is connected with engine crankshaft 6 by magnetic clutch 5, accessory belt pulley 3 and vacuum automobile pump 8 and 7 coaxial connections (as shown in Figure 3) of power steering pump with intergral reservoir, the use number that adopts this mode to connect also can to reduce motor.Air-conditioning compressor belt pulley 4 is connected with air-conditioning compressor by magnetic clutch, and motor 1, engine crankshaft belt pulley 2, accessory belt pulley 3 and air-conditioning compressor belt pulley 4 center on by belt 9 and be connected.
Magnetic clutch 5 magnetic clutchs on bent axle are in released state, motor 1 rotates as motor drives engine crankshaft belt pulley 2, accessory belt pulley 3 and air-conditioning compressor belt pulley 4, wherein engine crankshaft belt pulley 2 and air-conditioning compressor belt pulley 4 are idle running, use accessory belt pulley 3 driving automobile vacuum pumps 8 and power steering pump with intergral reservoir 7 work as idle wheel.When engine shutdown need start; magnetic clutch 5 adhesives; pressure is established vacuum pump 8 and is idle running; power steering pump with intergral reservoir 7 is a bypass; this moment, motor 1 drove engine starting by belt pulley 2; vacuum booster and steering hydraulic system can be kept work at short notice, and traffic safety is not had risk.Magnetic clutch 5 separates behind the engine starting, and system recovery is to original state, and motor 1 continues as vacuum automobile pump 8 and power steering pump with intergral reservoir 7 provides power.When automobile batteries need charge, with magnetic clutch 5 adhesives, this moment, driving engine drove motor 1 rotation by engine crankshaft belt pulley 2, motor 1 charges the battery as electrical generator, driving engine drives accessory belt pulley 3 simultaneously by engine crankshaft belt pulley 2 and rotates to vacuum automobile pump 8 and power steering pump with intergral reservoir 7 power is provided, magnetic clutch adhesive in the time of so on the air-conditioning compressor, engine crankshaft belt pulley 2 drives air-conditioning compressor work, for air-conditioning compressor provides power.
