Abstract
The utility model relates to a vacuum booster device for the brake of electric car, which is provided with a brake booster which is connected with a brake pedal; a vacuum chamber of the brake booster is communicated with a vacuum pump through a vacuum line; a return line and an in-line of the vacuum pump are respectively communicated with an inlet and an outlet of an oil storage cup; the oil storage cup is provided with an air vent. When a rotor of the vacuum booster pump is rotated by the external driving force of the vacuum booster pump, the lubricating oil inside the oil storage cup is absorbed into the pump body, after being circulated, the lubricating oil is returned to the storage cup again from the return line. When the rotor is rotated with the lubricating oil, a suction is generated for absorbing out the stored pressure air which is produced while braking, and the suction is returned to the oil storage cup with the lubricating oil through the return line, thereby the lubricating is sunk, and the air is discharged from the air vent in an upper cover, so that the safety performance of braking is improved.
Description
Technical field: the utility model relates to the vacuum booster pump that a kind of electrocar drag uses and the device of supporting braking, and particularly the brake of electrocar mechanical type utilizes vacuum pump to carry out power-assisted device.
Background technology: brake system, the frame mode more complicated of current all electrocar, even can reach the brake purpose, but the effect and the fuel oil car of brake more all can not show a candle to the fuel oil car.Make safety, the road-holding property of electrocar all be affected, its secure context can't ensure.Electrocar is generally many with electric brake, but because of its maneuvering performance does not have the maneuverability pattern of fuel oil car so sensitive, sets out on a journey to electrocar and move the hidden danger of bringing safety traffic.
Summary of the invention:
The purpose of this utility model is to solve the electrocar power-assisted technical matters of braking, and a kind of device of electrocar brake vacuum assist is provided.
Electrocar braking vacuum booster device of the present utility model, have and brake pedal bonded assembly brake servo-unit, it is characterized in that: the vacuum chamber of brake servo-unit is communicated with by vacuum line with vacuum pump, vacuum pump oil return line, vacuum pump chargine line are imported and exported with oil-storing cup respectively and are communicated with, and oil-storing cup has deflation hole.The utility model working process is achieved in that the brake vacuum assist pump externally during the rotation of the rotor in the power-driven pump, is drawn into the lubricating oil in the oil-storing cup in the pump housing, gets back in the oil-storing cup from oil return line again after the circulation.When the rotation of rotor and lubricating oil, will produce suction again the memory pressure air sucking-off that produces during brake in the servo-unit, together to get back to again in the oil-storing cup with lubricating oil by oil return line, lubricating oil sinks, and air is from the deflation hole discharge of loam cake.The brake safety performance of fast car is improved.
The utility model compared with the prior art, vacuum is the suction that is produced by tool machine transmission vacuum pump, makes stretcher very brisk when the operation air sucking-off in the known servo-unit.The booster vacuum of fuel oil car is by in-engine suction line, with the air-compressed gas sucking-off and the discharge of servo-unit.The utility model be utilize oil-sealed rotary pump by special-shaped rotor in lubricating oil in the pump and the pump externally machinery drive the backspin living suction of changing the line of production, get back in the oil-storing cup by oil return line again, the loam cake of oil-storing cup has air drain hole, air exhaustion, make braking quality reach safety rate by discharge orifice.
Description of drawings: accompanying drawing has been represented a kind of electrocar braking vacuum booster device structural representation of the present utility model, Fig. 1 is this electrocar braking vacuum booster device mounting structure scheme drawing, and Fig. 2 is this electrocar braking vacuum booster device vacuum oil air-flow scheme drawing.Among the figure: 1, mechanical type vacuum pump 2, brake servo-unit 3, oil-storing cup 4, vacuum pump oil return line 5, vacuum pump chargine line 6, vacuum pump vacuum line 7, each pipeline connect with clip 8, brake pedal 9, the heat radiation fan blade 10 of vacuum pump, vacuum pump drive pulley 11, oil-storing cup deflation hole 12, the unidirectional raft 13 of servo-unit, brake oil pipe
Example below in conjunction with accompanying drawing further specifies the utility model.
Specific embodiment: this utility model electrocar braking vacuum booster device, form by the pipeline of brake servo-unit, mechanical type vacuum pump, oil-storing cup and connection.The brake servo-unit has brake pedal, forms the connecting rod bonded assembly with brake pedal.The vacuum chamber of brake servo-unit is communicated with by vacuum line with the mechanical type vacuum pump, and mechanical type vacuum pump oil return line, vacuum pump chargine line are imported and exported with oil-storing cup respectively and be communicated with, and oil-storing cup top has deflation hole.
At first referring to Fig. 1: oil inlet among the figure (5) is connected with vacuum pump (1) upper end hole, and the lower port of vacuum pump (1) is connected with oil return pipe (4).At last vacuum line (6) is received on the middle interface of vacuum pump (1), the other end of vacuum line (6) is connected with the check valve (12) of servo-unit (2), tightens with clip (7) to get final product.
Referring again to Fig. 2: figure intermediate pump (1) flows to the lubricating oil in the oil-storing cup (3) in the vacuum pump (1) by chargine line (5) during by the exterior mechanical driven rotary.The suction that rotation produces mixes the pneumatics gas of servo-unit (2) internal memory after reversing sense enters air and lubricating oil in the oil-storing cup (3) from oil return line (4) with lubricating oil in vacuum line (6) inspiration vacuum pump (1), by deflation hole (11) with air exhaustion.Arrow among the figure in the A frame is represented the direction of flow, and cloud point is represented air.
The solution that organization plan of the present utility model is real the technical barrier of other electric brake and electric brake, make electrocar guarantee the safety factor of driving.
