Abstract
The utility model relates to an accessory wheel train which can take into account an EPS. The accessory wheel train comprises a generator, an air-conditioning compressor, a crank pulley, a tensioner, a water pump, a power steering pump and an idler wheel which are annularly connected by V- ribbed belts. The accessory wheel train is characterized in that the tensioner is positioned at the slack-side of the wheel train; the generator, the air-conditioning compressor and the tensioner are positioned at the intake side of the wheel train; the water pump and the power steering pump are positioned at the exhaust side of the wheel train. The generator, the air-conditioning compressor and the tensioner are arranged on a cylinder body through an accessory support; the power steering pump is directly arranged on a cylinder head. When a hydraulic power steering pump is switched to the electric power steering (EPS), the V- ribbed belts are just needed to be replaced, and the winding direction of which is partly changed on the basis of the previous arrangement of the wheel train, while the position and installation method of other parts of the whole wheel train do not need to be changed at all. Thus a switch of EPS has the least impact and change on the accessory wheel train.
Description
Technical field
The utility model relates to technical field of engines, relates to the front of the engine accessory wheel system specifically and arranges, particularly relates to the accessory wheel system of a kind of EPS of taking into account.
Background technology
Along with the further raising of people to automobile environment-protection, energy-conservation and security requirement, the EPS electric steering system becomes a development tendency with its many absolute predominance, and the beginning traditional hydraulic power-assisted steering pump of replacement progressively.At present, the front of the engine accessory wheel system comprises that electrical generator, air-conditioning compressor, tensioner, water pump, idle pulley, servo-steering pump constitute annular configuration in proper order and be made up of the polywedge bet connection.For general accessory wheel system, the hydraulic power-assisted steering pump changes the EPS electric steering system into, can cause the remodeling of whole accessory wheel system, need carry out again layout design to annex electrical equipment such as electrical generator, air-conditioning compressors, and need the new accessory mount of design that coupling is installed, equal to have developed again an accessory wheel system.
Summary of the invention
The purpose of this utility model is the deficiency that exists at existing accessory wheel system, and a kind of not only available hydraulic servo-steering pump, but also the accessory wheel system of interchangeable EPS are provided, and realizes that the switching of EPS is reduced to minimum to the influence and the change of accessory wheel system.
Technical scheme of the present invention is: a kind of accessory wheel system with the hydraulic power-assisted steering pump comprises electrical generator, air-conditioning compressor, tensioner, water pump, servo-steering pump, idle pulley and polywedge bet; It is characterized in that: the polywedge bet path of detouring is by electrical generator, air-conditioning compressor, crank shaft pulley, tensioner, water pump, servo-steering pump and idle pulley order.Tensioner is arranged in the train slack list, and electrical generator, air-conditioning compressor and tensioner are positioned at the air inlet side of accessory wheel system, and water pump and servo-steering pump are positioned at the exhaust side of accessory wheel system.Described electrical generator, air-conditioning compressor and tensioner are installed on the cylinder body by an accessory mount; Described hydraulic power-assisted steering pump direct mount is on cylinder cap, and described idle pulley direct mount is on timing cover.
A kind of accessory wheel system with the EPS electronic power assist steering comprises electrical generator, air-conditioning compressor, crank shaft pulley, tensioner, water pump, idle pulley and polywedge bet; It is characterized in that: the polywedge bet path of detouring is by electrical generator, air-conditioning compressor, crank shaft pulley, tensioner, water pump, idle pulley order.Tensioner is arranged in the train slack list, and electrical generator, air-conditioning compressor and tensioner are positioned at the air inlet side of accessory wheel system, is installed on the cylinder body by an accessory mount; Water pump and idle pulley are positioned at the exhaust side of accessory wheel system.
Consider simultaneously during the accessory wheel system layout design to have the polywedge bet of power-assisted steering pump belt wheel detour the path and adopt EPS after the polywedge bet of the no steering pump belt wheel path of detouring, to realize two kinds of shared these accessory wheel systems of steering swivel system (polywedge bet is the difference part).
Good effect of the present invention: switch to the EPS electric steering system by the hydraulic power-assisted steering pump, only need to change polywedge bet, and original accessory wheel system arrange change polywedge bet local on the basis around to, and other each component locations of whole train and mounting means all it goes without doing any change.Accessory wheel system of the present utility model is arranged the employing that can take into account hydraulic power-assisted steering pump and EPS electric steering system, reduces to minimum to the influence and the change of accessory wheel system the switching that realizes EPS.
Below with reference to drawings and Examples, the utility model is carried out comparatively detailed explanation.

Fig. 2 is that the accessory wheel system of taking into account the EPS electric steering system is arranged scheme drawing.
Among the figure: 1. electrical generator, 2. air-conditioning compressor, 3. tensioner, 4. water pump, 5. crank shaft pulley, 6. idle pulley, 7. polywedge bet.
The specific embodiment
The accessory wheel system of existing band hydraulic power-assisted steering pump comprises that electrical generator 1, air-conditioning compressor 2, crank shaft pulley 8, tensioner 3, water pump 4, idle pulley 5, servo-steering pump 6 orders constitute annular configuration and are made up of polywedge bet 7 connections as shown in Figure 1.Tensioner 3 is arranged in the train slack list, and electrical generator 1, air-conditioning compressor 2 and tensioner 3 are positioned at the air inlet side of accessory wheel system, is installed on the cylinder body by an accessory mount.Water pump 4, hydraulic power-assisted steering pump 6, be positioned at the exhaust side of accessory wheel system, hydraulic power-assisted steering pump 6 direct mounts are on cylinder cap.
Deposit two kinds of polywedge bets realizing adopting the hydraulic power-assisted steering pump and adopt EPS electric steering system path of detouring at same accessory wheel system cloth, changing under the minimum situation, take into account the layout of EPS.
