Description
Technical field
The utility model relates to a kind of Hydraulic Pump, specifically a kind of low noise frequency conversion steering pump.
Background technology
Along with the current progress of science and technology and the development of city traffic, electric vehicle replaces the vehicle based on burns gasoline gradually.Present atmosphere polluting problem is day by day serious, and exhaust emissions is the main source of atmospheric contamination, and the popularization of electric vehicle and improvement seem particularly important.
The steering pump of existing electrobus is that on the exposed mounting bracket being arranged on deflector side on the downside of chaufeur, steering pump operationally produces noise, affects the comfort level of chaufeur and passenger in car.Because steering pump mode of operation needs vehicle one startup to work, and just stop until vehicle does not travel or power motor does not work, electrical motor drives oil pump ceaselessly to operate always in the process, and hydraulic oil will produce the noise of very shrillness through oil pump and continue more than.Moreover the steering pump of exposed installation affects the overall appearance effect of city motor bus in chaufeur lower side hatch door.
In addition; existing steering pump can only by changing electrical motor model; namely change motor poles logarithm and reach the mode changing motor speed; just there is plurality of specifications model in so current used in new energy vehicles power-assisted steering pump; related fittings is also plurality of specifications; casting die also will much overlap, and brings the trouble of a lot of processing and manufacturing and production and assembly management, is unfavorable for large-scale production.
Utility model content
The purpose of this utility model is to provide a kind of low noise frequency conversion steering pump, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme:
A kind of low noise frequency conversion steering pump, comprise electrical motor, coupler and power-assisted steering pump, described electrical motor connects power-assisted steering pump by coupler; Also comprise double-deck soundproof box, and described electrical motor, coupler and power-assisted steering pump are arranged in double-deck soundproof box, three-phase terminal U, V, W of described electrical motor are electrically connected with three-phase terminal U, V, W of the frequency converter be arranged on above electrical motor respectively; Described double-deck soundproof box comprises ventilation inlet, skeleton, sound insulation filler, air outlet and erecting frame, and described ventilation inlet is provided with filter and ventilation inlet sound insulation net, and air outlet is provided with air outlet sound insulation net.
As further program of the utility model: described erecting frame and electrical motor, protective case and power-assisted steering pump contact portion are provided with insulating barrier.The coupling end outside of described electrical motor and power-assisted steering pump and coupler is provided with protective case.Insulating mat is provided with between described electrical motor and protective case.
Compared with prior art, the beneficial effects of the utility model are:
A kind of electrical motor of high rotating speed low cost, by the frequency control of frequency converter, is changed into the electrical motor of various rotating speed, for driving the power-assisted steering pump of different rotating speeds requirement by electrical motor described in the utility model.Achieve the noise reduction, dust-proof of steering pump additionally by double-deck soundproof box 1, exposed steering pump is originally wrapped up, enhances the stability of steering pump, add the aesthetics of this equipment simultaneously.
