Description
Technical field
The utility model relates to the brake system of vehicle, especially relates to a kind of jet complemental brake system of vehicle.
Background technology
Brake system on current automobile is mainly hydraulic braking and compression air brake, and common family-sized car substantially all uses hydraulic braking, and this brake system is primarily of compositions such as pedal, vacuum booster, master cylinder, wheel cylinder, brake discs.This kind of brake system is called as traditional vacuum assisted hydraulic brake system.
Auxiliary braking system is the effect can playing assist brake when main brake system goes wrong.Auxiliary braking system of the prior art is mainly adopted in two ways, and a kind of is friction based on increasing vehicle and ground; Another kind adds drg on wheel output shaft.The former is implementing inconvenience, easily occurs the problems such as overturning, wayward in the latter's braking procedure, easily allows wheel lockup, all there is potential safety hazard.
Summary of the invention
The purpose of this utility model is the deficiency existed for prior art, provides a kind of jet complemental brake system being convenient to control.
For achieving the above object, the technical scheme that the jet complemental brake system of the utility model adopts is:
A kind of jet complemental brake system, comprise suspension and chassis, damping spring is provided with between suspension and chassis, the first energy storage cylinder is also provided with between suspension and chassis, suspension drives the first energy storage cylinder to extrude gas when sinking or rise, and the mouth of the first energy storage cylinder is connected with accumulator by check valve, and accumulator is connected with storage tank, storage tank is connected with snifting valve, and snifting valve is connected with drg.Original drg installs snifting valve additional, can control brake system more accurately, absorbed the energy of suspension vibration by the first energy storage cylinder, saved the energy, the first energy storage cylinder has certain cushioning effect, improves the traveling comfort taken.
The second energy storage cylinder is also provided with between suspension and chassis, second energy storage cylinder is contrary with the useful effect direction of the first energy storage cylinder, suspension drives the second energy storage cylinder to extrude gas when rising or sink, and the mouth of the second energy storage cylinder is connected with accumulator by check valve.Second energy storage cylinder is contrary with the first energy storage cylinder useful effect direction, all can produce pressure gas and be transported to for assist brake in storage tank, improve the degree of utilization to automobile vibrational energy when suspension rises and sinks.
Described storage tank is provided with reducing valve.Reducing valve controls the pressure of storage tank, enables whole jet complemental brake system trouble free service.
Described reducing valve is connected with controller.The pressure of monitoring control devices storage tank, by reducing valve hold-off pressure during hypertonia.
Described snifting valve is connected with controller.Controller controls the speed of snifting valve release gas thus the auxiliary dynamics of control brake.
The utility model compared with prior art, has the following advantages:
The gas energy of suspension vibration generation is absorbed by the first energy storage cylinder, be connected with drg by snifting valve, play the effect of assist brake, be convenient to control assist brake, actv. make use of the vibrational energy of automobile, saved the energy, the first energy storage cylinder has certain cushioning effect, improves the traveling comfort taken.
Accompanying drawing explanation
Fig. 1 is the structural representation of the jet complemental brake system of the utility model.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, illustrate the utility model further, these embodiments should be understood and be only not used in restriction scope of the present utility model for illustration of the utility model, after having read the utility model, the amendment of those skilled in the art to the various equivalent form of value of the present utility model has all fallen within the application's claims limited range.
As shown in Figure 1, a kind of jet complemental brake system, suspension 1 and chassis 2, damping spring 3 is provided with between suspension 1 and chassis 2, the first energy storage cylinder 4 and the second energy storage cylinder 5 is also provided with between suspension 1 and chassis 2, the useful effect of the first energy storage cylinder 4 and the second energy storage cylinder 5 is contrary, suspension drives the first energy storage cylinder 4 to extrude gas when sinking, suspension drives the second energy storage cylinder 5 to extrude gas when rising, energy storage cylinder is all had to produce pressure gas in work during suspension double vibrations, first energy storage cylinder 4 is connected with accumulator 6 by check valve with the mouth of the second energy storage cylinder 5, accumulator 6 is connected with storage tank 7, storage tank is connected with snifting valve 8, snifting valve 8 is connected with drg.Storage tank is provided with reducing valve 71, reducing valve 71 and snifting valve 8 are all connected with controller (ECU) 9.
In vehicle traveling process, make body oscillating, suspension 1 Compress Spring of automobile because ground is uneven, and press down the piston of the first energy storage cylinder 4, the now one-way valve opens of the first energy storage cylinder 4, pressure gas enters accumulator 6.When the suspension 1 of automobile is with spring 3 return, the second energy storage cylinder 5 works, and pressure gas enters accumulator 6 by check valve, and high pressure gas are inputted storage tank 7 and store by accumulator 6.When automobile brake needs, control snifting valve 8 by controller (ECU) 9 and brake.The pressure of controller (ECU) 9 monitoring storage tank 7 controls the pressure of storage tank 7 by reducing valve 71, make whole system trouble free service.
Can avoid to a certain extent occurring major accident when main brake system goes wrong, allow automobile become safer.
