Abstract
The utility model relates to a belt wheel of an intelligent variable valve adjusting device, belonging to the field of vehicle parts. The belt wheel comprises a belt wheel (1), an oil pump bottom board (2) and an oil pump body (3); wherein the oil pump bottom board (2) and the belt wheel (1) are integrated; the oil pump body (3) and the belt wheel (1) are directly connected through connecting bolts(4); and the powder metallurgical material adopted by the belt wheel (1), the oil pump bottom board (2) and the oil pump body (3) is FC-0205-40. The belt wheel of the intelligent variable valve adjusting device has the advantages of low material cost and low manufacturing cost.
Description
(1) technical field
The utility model relates to a kind of intelligent variable valve adjusting device belt pulley.Belong to the auto parts field.Powder metallurgy automobile part field particularly.
(2) background technique
Along with the development of World Economics, fewer and feweri as non-renewable energy resources reserves such as oil, this makes national governments all encourage the research and development of the product that cuts down the consumption of energy.Intelligent alterable valve adjustments device (hereinafter to be referred as VVT) is the automobile fuel-saving device that at present international each big automobile factory has just released.The groundwork principle is for regulating the height on intake and exhaust doorway when motor car engine is worked by this device, energy and timely running condition according to automobile to utilize in-cylinder combustion residual air as quickening, slow down, at the uniform velocity situation is regulated engine output torque, to utilize the energy to greatest extent.The VVT belt wheel is the main composition parts of VVT system, mainly participates in belt transmission by external tooth, and engine speed is reflected to the VVT system, plays the timing effect of control valve height.
Intelligent variable valve adjusting device belt pulley is mainly used in the family expenses sedan car of 1.6L-2.4L discharge capacity.Used powdered metallurgical material is: FD-0205-50.Its structural design is made up of belt pulley, oil pump base plate, pump body and bearing shown in Fig. 5～7.The oil pump base plate adopts punching press A3 steel part.Connect by bolt and belt wheel.Bearing connects by soldering and pump housing base plate.It mainly has the following disadvantages:
1, used powdered metallurgical material is: FD-0205-50, cost of material is higher relatively.
2, belt pulley adopts bolt to be connected with the oil pump base plate, and as Fig. 5～7, union piece is many, and assembling procedure is many, and material and manufacture cost are higher relatively.
(3) summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of material and manufacture cost relatively low intelligent variable valve adjusting device belt pulley.
The purpose of this utility model is achieved in that a kind of intelligent variable valve adjusting device belt pulley, described controlling device belt wheel comprises belt pulley, oil pump base plate and pump body, described oil pump base plate and belt pulley adopt integrated design, directly connect with coupling bolt between described pump body and the belt pulley; Described belt pulley, oil pump base plate and the used powdered metallurgical material of pump body are: FC-0205-40.
Compare with intelligent variable valve adjusting device belt pulley in the past, the utlity model has following characteristics:
1, the 0-5000rpm (engine speed that works in the VVT system, as follows) in, by the finite element modelling analysis, discovery is in 1.6L～2.4L engine system, the maximum stress of the extreme working state of VVT belt wheel appears at the middle part, and promptly near 2200 commentaries on classics, it is the most heavily stressed to be 113Mpa (as Fig. 1), consider 25% safety coefficient, design stress is＞135Mpa.With reference to the MPIF-35 standard, selecting to be fit to material trademark is FC-0205-40, and its fatigue strength (fatigue stress) is 140Mpa, and is the most approaching with target, and the relative FD-0205-50 of cost reduces by 50%.
2, discard bolt connection belt pulley and oil pump base plate mode in the past, can reduce six of original system parts (connecting bolt), reduce assembling procedure three roads.But the original structure base plate is fine and close steel plate, and powder metallurgy belongs to not dense material, has the leakage of oil risk as the oil pump base plate.Because of oil pump work rated pressure is 1.0Mpa, design is decided to be this belt wheel sealing＞1.5Mpa.For reaching this purpose, by with the VVT belt wheel in 550 ℃ of steam treatment 2h, the space that makes VVT belt wheel inside is by fine and close Fe
3O
4Fill full.Sealing can reach 1.7～2.3Mpa, has solved the leakage of oil risk fully.By the steam treatment operation, other physical properties of VVT belt wheel are constant or lifting (accompanying drawing 8) arranged slightly.
3, the utility model belt wheel has " timing " function and " pump body " function simultaneously, reduces mass of system 0.9kg simultaneously.Adopt powder metallurgical technique simultaneously, make the suitable production in enormous quantities of powder metallurgy, steady quality, material-saving is economized energy.
To sum up, adopt intelligent variable valve adjusting device belt pulley of the present utility model, reduce by five parts than at present general in the world VVT belt wheel, reduce assembling procedure four roads, analyzing definite material by finite element modelling is the common FC-0205-40 rather than the FD-0205-50 of present used costliness, obtained very big economic effect: can save cost 72% altogether, per ten thousand 62000～94000 yuan of product escapable costs (being used for engine displacement 1.6L-2.4L on part decides).
