Abstract

The utility model discloses a turbine starting device, mainly composed of a starting motor (1) with a worm, and a worm wheel (2) in which a roller one-way clutch is arranged. The utility model as the starting device of an automobile has the advantages of obvious reduction of the loads of a starter and an accumulator, small volume, light weight, low noise, superior starting performance, high reliability, various forms for installation, etc.

Description

Turbine starter

The utility model relates to automobile electrical appliances, more specifically to a kind of worm gear starting arrangement.

The widely used automobile electric starting device of prior art is with the driving pinion of overrunning clutch, compositions such as flywheel ring gear by dc starter.Connect power supply, starter motor is meshing by driving pinion and the flywheel circle of band overrunning clutch, drives bent axle and realizes startup.But because mounting point (starter motor only limits to be installed in the engine flywheel side) and the minimum number of teeth of driving pinion and the reasons such as maximum sized restriction of flywheel ring gear, and define velocity ratio.During starting, the load of starter motor and storage battery is very big, for making motor obtain enough starting torques and necessary rotating speed, thereby have to select for use actuating motor and the storage battery of high power capacity and the thicker starting power supply line of the slow-speed of revolution, high moment of torsion, and each starting time must not surpass 5 seconds kinds.The starter motor life-span is short.。External once had adopt the starter motor that secondary gear slows down to improve velocity ratio, but the complex structure that seems, volume are big.

The utility model purpose is to provide a kind of worm gear starting arrangement that overcomes the prior art deficiency.

The purpose of this utility model is to realize like this, promptly construct a kind of Turbine starter, comprise the actuating motor (1) of being with worm screw, the worm gear (2) of interior band roller one-way clutch, actuating motor (1) seal ring of described band worm screw reaches by connecting screw (3) and laterally is installed on the Timing gear cover (4), and the worm gear of described band roller one-way clutch (2) is fixed in the front end of bent axle (6) by flat key (5).

The utility model worm gear starting arrangement is characterised in that starting arrangement no longer vertically is installed in the flywheel side but laterally is installed in crankshaft front end, and worm gear, worm screw and roller one-way clutch are lubricated by engine oil.Owing to adopted Worm wheel transmission mechanism, velocity ratio is big (can reach more than the 30:1), therefore: the actuating motor that can select higher rotation speed, low moment of torsion for use.

The utility model worm gear starting arrangement another feature also is.Not only can be installed in motor head, also change the tactic pattern of traditional starting arrangement, and set up a kind ofly, make the integral layout of automobile more be tending towards reasonable as the new tactic pattern of the annex in the transmission assembly as an annex in the engine assembly.(because the outer attachment of engine assembly remaining space too many, engine bin is limited, and transmission assembly does not almost have outer attachment, and space on every side is very big.）

Implement the utility model worm gear starting arrangement, can significantly reduce the load of starter motor and storage battery, all can improve working life, all can correspondingly reduce in the weight and volume of starter motor, the capacity of storage battery and starting power supply line line footpath, and these are very favourable to alleviating light weight; Lubricate owing to had, do not have impact phenomenon during starting.Noise obviously reduces: the change of starting arrangement mounting point.To bring greater flexibility to the integral layout of the front wheel drive type sedan car of compact structure, and make starting arrangement be easier to keep in repair, maintain.The utility model device is suitable for all kinds of motorcycles equally.

With reference to accompanying drawing, enforcement of the present utility model is described further.

Fig. 1 is the utility model structural representation;

Fig. 2 is the flywheel engagement starting arrangement schematic representation that generally adopts;

Fig. 3 is that the utility model worm gear starting arrangement is installed in the schematic representation on the speed changer;

As shown in Figure 1, the utility model worm gear starting arrangement is by the actuating motor (1) of band worm screw, the worm gear (2) of interior band roller one-way clutch is formed, the actuating motor (1) of described band worm screw laterally is installed on the Timing gear cover (4) by connecting screw and seal washer (3), the worm gear (2) of band roller one-way clutch is fixed on the front end of bent axle (6) in described by flat key (5), connect power supply, power is realized starting by worm gear (the 2) → bent axle (6) of actuating motor (1) → interior band roller one-way clutch of band worm screw, after the startup, because the effect of roller one-way clutch, motor can not drive actuating motor.

Shown in Figure 2, the flywheel geared assembly that generally adopts is connected power supply at present, and power is by driving pinion (11) → flywheel ring gear (the 12) → bent axle (6) of actuating motor (10) → band overrunning clutch, and realization starts.

Shown in Figure 3, for the utility model worm gear starting arrangement is installed in structural representation on the speed changer, laterally is installed in and is with the worm gear (2) of roller one-way clutch to be fixed on the transmission drive shaft (8) in transmission case (7) front end by connecting screw and seal washer (3) by flat key (5) by the actuating motor (1) of described band worm screw.Connection power supply, power are bribed worm gear (2) → transmission drive shaft (8) → main clutch (the 9) → bent axle (6) of clutch by actuating motor → interior band roller list of band worm screw, and realize starting.

Claims

1, a kind of worm gear starting arrangement, it is characterized in that comprising the actuating motor (1) of being with worm screw, the worm gear (2) of interior band roller one-way clutch, described band worm screw actuating motor (1) laterally is installed on the Timing gear cover (4) by connecting screw and seal washer (3), and the worm gear (2) of described interior band roller one-way clutch is fixed on the front end of bent axle (6) by flat key (5).

According to the described worm gear starting arrangement of claim 1, it is characterized in that 2, the worm gear integral body of band roller one-way clutch was lubricated by engine oil in the worm screw in the actuating motor (1) of described band worm screw partly reached.

3, according to the described worm gear starting arrangement of claim 1, its feature also is, the starting of described band worm screw, motor (1) also can laterally be installed in transmission case (7) front end by connecting screw and seal washer (3), the worm gear (2) of band roller one-way clutch is fixed on the transmission drive shaft (8) by flat key (5) in described.
