Abstract
The utility model relates to a driving device, particularly relates to a steering monoblock pump for electric vehicles. The driving device comprises an electric motor and a power steering pump. A coaxial coupling is provided between and to connect the output shaft of the electric motor and the input shaft of the power steering pump. Because the utility model adopts such monoblock driving device which connects the output shaft of the electric motor and the input shaft of the power steering shaft by a coaxial coupling, as a result, deficiencies of traditional belt driving devices (such as low driving efficiency, big electric consumption, occupation of large space) are effectively overcome. Because the driving device does not use any belt pulley of the output shaft end of the electric motor and any belt pulley of the input shaft end of the power steering pump, but replaced by a coaxial coupling to connect the output shaft of the electric motor and the input shaft of the power steering pump, the structure is relatively compact, the coaxially connected devices cover a small space, the service performance is stable, the driving performance is high and energy efficient, and hidden safety troubles can be eliminated substantially.
Description
Technical field
The utility model relates to a kind of transmission device of Electric, particularly a kind of Electric straight connection type power assistance pump for steering.Also can be used for as the Electric directly coupled type air compressor.
Background technique
At present, the motor of traditional Electric is connected with power assistance pump for steering, the transmission device that all adopts belt transmission to connect promptly links together the belt pulley of the motor output shaft end of axial parallel arrangement and the belt pulley of power assistance pump for steering input shaft end by drivign belt, comes transmitting power.But, drivign belt in this transmission device is limited by the mounting point, in use performance is unstable, if diaxon is not parallel or belt is loose excessively, the easy sideslip of belt comes off, and influences the electric car cruising, if diaxon is at a distance of too far away or excessive belt stretch, sometimes even can break, cause the sudden hurt accident of driving because of the unexpected excessive belt that makes of load.Belt Transmission Efficiency is low in addition, and noise is big, not only power consumption big, increase taking up room of equipment, the overall volume of electric car is strengthened, but also has serious potential safety hazard.
The model utility content
The purpose of this utility model provides a kind of Electric straight connection type power assistance pump for steering, the transmission efficiency that it has overcome the conventional belt transmission device effectively is low, power consumption greatly, the defective that takes up room more, has compact structure, equipment occupation space is little, usability is stable, the transmission efficiency height, energy-conservation, the advantage that fundamentally eliminates safe hidden trouble.
The purpose of this utility model is achieved in that this device comprises motor and power assistance pump for steering, and its technological points is: adopt coaxial coupling directly to link into an integrated entity between described motor output shaft and the power assistance pump for steering input shaft.
Because the utility model adopts the straight connection type transmission device that directly motor output shaft and power assistance pump for steering input shaft is linked into an integrated entity by coaxial coupling, thus overcome effectively that the transmission efficiency of conventional belt transmission device is low, power consumption greatly, the defective that takes up room more.Because of this transmission device has been cancelled the belt pulley of motor output shaft end and the belt pulley of power assistance pump for steering input shaft end, substitute belt with same axial coupling, motor output shaft and power assistance pump for steering input shaft are directly linked into an integrated entity, so it has compact structure, the equipment occupation space of coaxial connection is little, and usability is stable, the transmission efficiency height, energy-conservation, as fundamentally to eliminate safe hidden trouble advantage.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is a kind of concrete structure schematic representation of the present utility model.
Embodiment
Describe concrete structure of the present utility model in detail according to Fig. 1.This device is improved on the basis of existing Electric transmission device.It comprises parts such as motor 4, power assistance pump for steering 1 and coupling 3.Wherein the input shaft of the output shaft of motor 4 and power assistance pump for steering 1 is arranged on the coaxial line, adopts coaxial coupling 3 directly to link into an integrated entity between the diaxon.Coupling 3 in the present embodiment adopts the glue gear coupling, also can adopt other like product.When the basal plane of the support of motor 4 and the pump housing connecting base of power assistance pump for steering 1 is vertical mutually, between the pump housing connecting base of the support of motor 4 and power assistance pump for steering 1, can adopt form connection as shown in Figure 1 with the pump support.When the basal plane of the pump housing connecting base of the support of motor 4 and power assistance pump for steering 1 is parallel to each other, also the support of motor 4 can be placed on the same fixed base with the pump housing connecting base of power assistance pump for steering 1 and be connected.
Power assistance pump for steering 1 in this device is substituted with air compressor, just the input shaft of the output shaft of motor 4 and air compressor is arranged on the coaxial line, adopt coaxial coupling 3 directly to link into an integrated entity between the diaxon, promptly this device also can be used as the use of Electric directly coupled type air compressor.
Claims (2)
1, a kind of Electric straight connection type power assistance pump for steering comprises motor and power assistance pump for steering, it is characterized in that: adopt coaxial coupling directly to link into an integrated entity between described motor output shaft and the power assistance pump for steering input shaft.
2, Electric straight connection type power assistance pump for steering according to claim 1, it is characterized in that: described power assistance pump for steering substitutes with air compressor, the output shaft of motor and the input shaft of air compressor are arranged on the coaxial line, adopt coaxial coupling directly to link into an integrated entity between the diaxon.
