The hydraulic combined braking system provided by the utility model can control the initial braking time of the front and the rear wheels of a two-wheel motorcycle by sensing the input pressure of the braking main pumps via the valves, and realizes reasonable distribution of the front and the rear braking forces, so as to improve the braking stability and the safety of motorcycles.
Description
Technical field
The utility model relates to the hydraulic combined brake system of a kind of motorcycle brake system, particularly a kind of motor bike.
Background of invention
The brake system of present most of motor bikes is forward and backward system independently separately, and when emergency braking, if be applied to the lock torque that the friction moment on the drg can provide greater than the road surface, locking will take place wheel.If the locking of front-wheel elder generation, then motor bike loses steering capability, if then can not be according to predetermined route running on bend.If the locking of trailing wheel elder generation, the sideslip that under the effect of external force, can cause danger, even make motor bike produce tune (being commonly called as whipping).Therefore, the split braking system has relatively high expectations to the personnel's of driving driving technique.Improving deceleration and stopping performance and keeping the stable actv. way of glancing impact direction is that brake anti-lock device (ABS) is installed, but the relative raising with manufacture difficulty of manufacturing cost is a lot, so, generally in big discharge capacity, at a high speed, just brake anti-lock device can be installed on the high-grade motor bike.
Front and back wheel associated braking system (Combined Brake System) is called for short CBS, promptly is by the mono-controller being carried out brake operating, realizing the braking of front and back wheel.The present domestic preceding hydraulic disk of being mainly of motorcycle field, the back stay drum-type CBS system of being used in, its principle of work is: during brake activation main pump pull bar, the pressure that acts on the brake main pump passes to preceding brake caliper by hydraulic tubing on the one hand, the brake main pump pull bar is realized the braking of Back-braking drum by mechanical connection mechanism pulling back brake cable pull on the other hand.The preceding brake response sensitivity of this brake system will overcome more mechanical friction and mechanical error but brake the back, and reacting phase is to slow, and the harmony of front and back wheel braking also is difficult to obtain guaranteeing comparatively accurately.
Summary of the invention
Goal of the invention: the purpose of this utility model provides the hydraulic combined brake system of a kind of front and back brake coordination, safe and stable motor bike.
Technical scheme: the hydraulic combined brake system of motor bike described in the utility model comprises left brake main pump assembly, right brake main pump assembly, braking assignment latency valve assembly, preceding brake caliper assembly, back brake caliper assembly and brake pipe; Wherein preceding brake caliper is floating type side three cylinders, and first oil cylinder and the 3rd oil cylinder are communicated with, and second oil cylinder is independently; Back brake caliper is the opposed twin-tub of fixed type, and two cylinders are communicated with; Left side brake main pump assembly is communicated with forward and backward brake caliper by braking assignment latency valve assembly, and right brake main pump assembly is communicated with preceding brake caliper separately.
Principle of work of the present utility model is: the and arranged on left and right sides of car handgrip is fixed with left and right brake main pump assembly (hand brake mode) respectively, second oil cylinder before left brake main pump assembly is controlled simultaneously by braking assignment latency valve assembly in the brake caliper and two oil cylinders of back brake caliper; First oil cylinder and the 3rd oil cylinder before right brake main pump is then controlled separately in the brake caliper.When driver and crew handled left brake main pump assembly with left hand, the pressure that left brake main pump produces was directly inputted in the oil cylinder of back brake caliper by braking assignment latency valve etc. big or smallly, makes trailing wheel produce braking immediately.When the pressure of left brake main pump generation surpasses certain value, the oil duct of brake caliper was open-minded before braking assignment latency valve was communicated to, the pressure that left brake main pump is produced is sent in second oil cylinder of preceding brake caliper according to the scale of setting, and makes front-wheel produce braking.And at a high speed when braking or emergency braking, left hand and right hand is handled left and right brake main pump respectively, the pressure that right brake main pump produces is directly inputted in first oil cylinder and the 3rd oil cylinder of two connections in the preceding brake caliper, increases the braking force of front-wheel apace, so that shorten stopping distance to greatest extent.Simultaneously, this has also satisfied 93/14/EEC, ECE R78.02 and GB 20073-2006 about " motor bike and trail bike deceleration and stopping performance and test method ".In addition, can regulate and control the distribution of front and back wheel braking force by controlling right brake main pump, improve the stability and the safety of braking according to different condition of road surfaces.
Braking assignment latency valve is most critical parts of realizing the brake system front and back linkage.On the one hand, it is delivered to the pressure that left brake main pump transmits on the piston of forward and backward brake caliper according to a certain percentage, the reasonable distribution of front and rear wheel braking force before and after realizing; On the other hand, it can guarantee that the time that trailing wheel begins to brake always is slightly ahead of front-wheel, that is to say that the braking to front-wheel has certain delayed-action, thereby, be called braking assignment latency valve.
As seen from Figure 2: when braking assignment latency valve is experienced input pressure, will by the direct mouth of pressure equal big or small pressure be input on the piston of back brake caliper immediately, produce the braking force of trailing wheel.At this moment, trailing wheel begins braking, produces and drags moment, and car reduces speed now.When increasing to BMPa gradually along with the input pressure in the pressure input end in the delay valve, pressure retarded mouth is just exported the preliminary examination pressure of AMPa, and this pressure increases along with the increase of input pressure according to a certain percentage, and on the piston of brake caliper, front-wheel began braking before this pressure was input to.The length that front-wheel postpones the time of braking with respect to trailing wheel depends on the speed that the size that is input to the pressure in the delay valve and pressure increase.During emergency braking, input pressure sharply rises to maximum in the extremely short time, and the front and back wheel of car also is similar to synchronous braking.Can realize being complementary by the setting that changes A, B value with different vehicles.
Beneficial effect: associated braking system described in the utility model is not simply the hydraulic tubing of front and back wheel to be communicated with, but experience the input pressure of brake main pump by special valve means, control the initial braking time of two-wheeled motorcycle front and back wheel, and realize of stability and the safety of the reasonable distribution of front and back braking force with the raising motorcycle brake.This brake system can overcome potential safety hazards such as the floating act in glancing impact motor bike head sedimentation rear portion, braking deviation, rollover, whipping effectively, reduces driver and crew's driving fatigue, makes the traveling comfort that drives of car load strengthen.
