The utility model mainly solves the problems that the discharge of the existing vacuum pump of the electric automobile is smaller than the rotary vacuum pumping discharge of a motor of a gasoline automobile, the power-assisted requirement for the brake can not be satisfied completely when the automobile runs, and the safety of persons and the automobile can not be ensured when the automobile is in an emergency. The utility model comprises a vacuum brake booster (1) and a vacuum pump (3). The utility model is characterized in that an air storage tank (2) is connected between the vacuum brake booster (1) and the vacuum pump (3), and the vacuum brake booster (1), the air storage tank (2) and the vacuum pump (3) are connected by vacuum pipelines (6).
Description
Technical field
The utility model relates to a kind of automobile braking device, especially relates to a kind of to having the isostructural improvement of electronlmobil braking vacuum booster device of storage tank.
Background technology
It is very universal that automobile all is furnished with the power-assisted use of brake power-assisted, especially vacuum brake basically at present.Its principle is that the negative pressure and the difference of pressure between the barometric pressure that produce when utilizing engine operation force the interior rubber diaphragm of brake vacuum assist device to move, and promotes the piston of master brake cylinder, alleviates the power that the people steps on brake pedal with this.Electronlmobil has become the developing direction of following automobile, and as drive energy, it has characteristics such as pollution is little, and noise is little, and is energy-conservation with electric energy for it.But present electronlmobil generally converts on the prototype of gasoline car, the work characteristics when therefore a lot of things also keep driving engine.In gasoline car, mainly be to lean on the rotation of driving engine constantly to vacuumize, to guarantee to have certain brake power-assisted.Driving engine is replaced by electrical motor in electronlmobil, but electrical motor can not rotate as driving engine always, so generally all be ceaselessly to vacuumize now by a vacuum pump, also can realize the power-assisted of braking although it is so, but the vacuum pump discharge capacity of electronlmobil use is now compared with the discharge capacity that the gasoline vehicle engine rotation vacuumizes or is less, in the time of can not satisfying vehicle ' fully to the power-assisted requirement of braking, at vehicle in case of emergency, the safety of personnel and vehicle can not be guaranteed.
Summary of the invention
The utility model provides a kind of electronlmobil braking vacuum booster device, its subject matter is to solve because the vacuum pump discharge capacity that electronlmobil uses is now compared with the discharge capacity that the gasoline vehicle engine rotation vacuumizes or be less, in the time of can not satisfying vehicle ' fully to the power-assisted requirement of braking, at vehicle in case of emergency, the safety of personnel and vehicle can not be guaranteed.
Above-mentioned technical matters of the present utility model is mainly solved by following technical proposals:
Electronlmobil braking vacuum booster device of the present utility model comprises brake vacuum assist device, vacuum pump, is connected with storage tank between described brake vacuum assist device and the vacuum pump, connects with vacuum line therebetween.Add storage tank, increased the capacity of vacuum in the brake vacuum assist system, the needs when making the brake vacuum assist system satisfy vehicle ' fully also make simultaneously when the vacuum pump type selecting, can select the less vacuum pump of discharge capacity.
As preferably, described brake vacuum assist device, vacuum pump, storage tank are connected with vacuum-pressure detection equipment by vacuum line, and vacuum-pressure detection equipment, vacuum pump are connected with the vacuum brake controller by circuit simultaneously.Add vacuum-pressure detection equipment and vacuum brake controller and just can control the mode of operation of vacuum pump according to the operation conditions of vehicle.
As preferably, the capacity of described storage tank is 1.5L～3L.The capacity of storage tank generally can be set at 2L, and its capacity and brake vacuum assist device and vacuum capacity of pump adapt.
As preferably, the vacuum brake controller makes the range of pressure of whole vacuum brake force aid system be :-0.03Mpa～-0.08Mpa.Prescribe a time limit when degree of vacuum reaches, vacuum brake controller control vacuum pump quits work; Prescribe a time limit when degree of vacuum reaches down, vacuum brake controller control vacuum pump is started working.
As preferably, vacuum-pressure detection equipment is vacuum pressure switch.It can detect single limit value or two limit value degree of vacuum.
As preferably, vacuum-pressure detection equipment is vacuum pressure sensor.It can guarantee the sensitivity of vacuum-pressure detection.
Therefore, it is safe in utilization, reliable to the utlity model has the brake servomechanism.Add storage tank, increased the capacity of vacuum in the brake vacuum assist system, the needs when making the brake vacuum assist system satisfy vehicle ' fully also make simultaneously when the vacuum pump type selecting, can select the less vacuum pump of discharge capacity.
Description of drawings
Accompanying drawing 1 is a kind of structural representation of the present utility model.
The specific embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: the electronlmobil braking vacuum booster device that this is routine, as Fig. 1, a brake vacuum assist device 1 is arranged, it is connected with storage tank 2, vacuum pump 3, can detects the vacuum pressure switch 4 of two position degree of vacuum by vacuum line 6, and wherein vacuum pressure switch 4, vacuum pump 3 are connected with vacuum brake controller 5 by circuit 7 simultaneously.Be limited on the vacuum degree control of vacuum brake controller 5-0.08Mpa, be limited to-0.03Mpa down.The capacity of storage tank 2 is 2L, and the free air capacity of itself and vacuum pump 3 adapts.
Behind the vehicle launch, if the degree of vacuum in the vacuum brake force aid system is lower than-0.03Mpa, signal of vacuum pressure switch 4 outputs is given vacuum brake controller 5, and vacuum brake controller 5 starts vacuum pump 3 work immediately.When in the vacuum brake force aid system during degree of vacuum arrivals-0.08Mpa, vacuum pressure switch 4 sends signal to vacuum brake controller 5, and the vacuum brake controller just quits work vacuum pump 3 immediately.Add storage tank 2, increased the capacity of vacuum in the brake vacuum assist system, the needs when making the brake vacuum assist system satisfy vehicle ' fully also make simultaneously when the vacuum pump type selecting, can select the less vacuum pump of discharge capacity.
