Description
Technical field
The utility model relates to for the vacuum pump structure in brake system of car, specifically a kind of gear-driving vacuum pump.
Background technique
In brake system of car, usually negative pressure power is provided to carry out brake by vacuum pump.In existing Vehicular system, usually operated by motor drive electrical generators while outputting power, drive vacuum pump running by generator drive axle.Its defect is: 1, transmission link is many, assembling and positioning link is many, and positioning precision is not high, vacuum performance poor stability; ; 2, vacuum pump is arranged on generator usually, by generator drive, drives link many, and vacuum pump affects by generator failure the possibility producing inefficacy and increases; 3, because vacuum pump is arranged on generator, the exhaust pipe of vacuum pump, various pipeline such as exhaust drain line, in-line etc. are complicated, take up room comparatively large, constrain motor, the outward appearance of generator and spatial design.
Summary of the invention
Technical problem to be solved in the utility model is, provide a kind of structure simple, manufacture and easy for installation, that parts are few, space hold is little, Reliability of Microprocessor is high gear-box integrated form vacuum pump.
Gear-driving vacuum pump of the present utility model includes housing, the bleeding point be positioned on housing, for inject lubricant oil filler opening, for being vented and the relief opening of removal of lubricant, the rotor being positioned at housing, blade, live axle; Described housing is connected directly between on the casing of engine gearbox; The power intake of described live axle is positioned at engine gearbox, and described power intake is by input gear and the power gear engagement driving by driven by engine; The outer end opening of described relief opening is positioned at engine gearbox.
Described exhaust outer end opening place is provided with unloading valve.
Vacuum pump is integrated on engine gearbox by the utility model, is directly installed on engine interior driving gear, drives the running of vacuum pump live axle, and not only compact structure, space hold are little, and the few reliability of transmission link is high; In addition, the lubricating oil path due to vacuum pump is integrated in housing and gear housing, and the lubricant oil of discharge directly gets back to lubricating oil tank, eliminates the oil pipe of peripheral hardware, install simple and convenient, good airproof performance, manufacture difficulty are low, reduce manufacture cost.
Accompanying drawing explanation
Fig. 1 is cross-sectional view of the present utility model;
Fig. 2 is left end face view.
Embodiment
As shown in the figure, this gear-driving vacuum pump include housing 1, the bleeding point be positioned on housing, for inject lubricant oil filler opening, for being vented and the relief opening 2 of removal of lubricant, the rotor 3 being positioned at housing and live axle 4 and blade 5; Housing 1 is connected directly between on the casing of engine gearbox 8; The power intake of live axle 4 is positioned at engine gearbox 8, and power intake is by input gear 6 and power gear 7 engagement driving by driven by engine; The outer end opening of relief opening 2 is positioned at engine gearbox 8.Working procedure rotor rotates and produces negative pressure, forms vacuum source by intakeport air-breathing, and lubricant oil is injected by filler opening and lubricates rotor, then discharges from relief opening 2 with the air of discharging.The outer end opening place of described relief opening 2 is provided with unloading valve 9, to ensure that in breathing process, corresponding chambers is closed.The outer end opening place of bleeding point is provided with one-way valve a.
Claims (2)
1. a gear-driving vacuum pump, include housing (1), the bleeding point be positioned on housing, for inject lubricant oil inlet port, for being vented and the relief opening (2) of removal of lubricant, the rotor (3) being positioned at housing, live axle (4) and blade (5); It is characterized in that: described housing (1) is connected directly between on the casing of engine gearbox (8); The power intake of live axle (4) is positioned at engine gearbox (8), and power intake is by input gear (6) and power gear (7) engagement driving by driven by engine; (2) outer end opening of described relief opening is positioned at engine gearbox (8).
