Description of drawings
By reference to the accompanying drawings, the utility model is further described:
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model assembling decomposing schematic representation;
Wherein, 1 is pedal base; 2 is pedal support; 3 is the pedal upper arm; 4 is the pedal underarm; 5 is nut.
The specific embodiment
As shown in Fig. 1-2, technical scheme provided by the utility model is, the brake pedal of adjustable lever, comprise pedal base 1, pedal support 2, pedal arm, described pedal arm is arranged on described pedal support 2, and described pedal support 2 is arranged on described pedal base 1, described pedal base 1 is connected with car body by bolt, described pedal arm is made of two parts of upper and lower separation, and two parts of described pedal arm are subjected to displacement relatively, and is adjustable on described pedal arm length direction.Described pedal arm comprises pedal upper arm 3 and pedal underarm 4, and described pedal upper arm 3 and pedal underarm 4 be along mutually sliding on the pedal arm length direction, and is bolted.Described pedal upper arm 3 is provided with pedal upper arm 3 " O " the shape groove, described pedal underarm 4 is provided with pedal underarm 4 " O " and the shape groove, described pedal upper arm 3 " O " length of shape groove is less than described pedal underarm 4 " O " length of shape groove.Described " O " be provided with two or more bolts, described pedal upper arm 3 in the shape groove " O " shape groove and described pedal underarm 4 " O " the shape groove is bolted.The technical solution of the utility model also can adopt another kind of mode to realize that pedal arm is adjustable, and pedal upper arm 3 and pedal underarm 4 are along being provided with two or more circular fixed orifices on the pedal arm length direction as described.Be provided with bolt at least two circular fixed orifices of described pedal upper arm 3 and pedal underarm 4.Described pedal upper arm 3 and described pedal underarm 4 be along being subjected to displacement on the pedal arm length direction, and be bolted.
Embody the assembly relation of each part as Fig. 2.The brake pedal of a kind of adjustable lever ratio provided by the utility model mainly consists of pedal upper arm 3, pedal underarm 4, bolt, nut 5, pedal support 2 by following.Pedal arm upper arm and pedal underarm 4 have respectively one " O " the shape groove, bolt passes " O " shape groove and pedal upper arm 3 and pedal underarm 4 being connected and fixed by nut 5, thus satisfy the normal operating needs of pedal.Simultaneously tumble in scale on two pedal arms, can read easily the length of pedal arm.
In deceleration and stopping performance matching test process in order to adjust lever ratio pedal sense to be adjusted to optimum.Can will adjust by the following method: at first unclamp nut 5; Next adjusts two " O " relative position of shape groove, thus change the length of pedal arm, to reach desirable lever ratio; Again locking nut 5 gets final product at last.
Can illustrate from above structure, this pedal in use, can be according to the different demand Self-adjustment foot pedal lever ratios to pedal sense of chaufeur, more can be for the brake system Performance Match provide pedal parameter comparatively easily, thus design pedal sense brake system preferably.
Generally, the automobile brake pedal operation is divided into: slowly braking (being the foresight braking), emergency braking, Associated brake and intermittent braking.Generally, at wheel lockup with before stopping, all pedal of clutch to be stepped on earth when slow braking and emergency braking, in order to make driving engine not stop working and be conducive to the speed of a motor vehicle of remapping:
1. slowly braking.Depress pedal of clutch, close the throttle simultaneously is pushed into the bottom gear position with shifter bar, lifts immediately pedal of clutch, and right crus of diaphragm is placed on rapidly on brake pedal, the speed of a motor vehicle and point station distance as required, and the lower brake pedal that presses down with the foot gradually is until stop.
2. emergency braking.Emergency braking when emergency braking is divided into middle low speed driving again and the emergency braking when running at high speed.Emergency braking during middle low speed driving: both hands are held steering handwheel, depress fast pedal of clutch, almost depress simultaneously brake pedal, take a foot-operated dead method, and car is stopped rapidly.Emergency braking when running at high speed: because the speed of a motor vehicle is high, inertia is large, poor stability, in order to increase the stability of brake efficiency and raising automobile, should first depress brake pedal during operation, before wheel lockup. depress again pedal of clutch, pin down the speed of a motor vehicle to utilize the driving engine slow speed of revolution.After wheel lockup, front-wheel steering is get out of hand, and vehicle body easily breaks away.Can the main points that emergency braking needs to be grasped be: because of seized rear steering get out of hand, advance to when very near apart from obstacle at the inertia of auto in Braking, can see the car that stop according to the speed of a motor vehicle, make vehicle stop in the time of stopping car as far as possible, need detour when stopping incessantly.Answer the loosen the brake pedal when detouring, make steering handwheel play control action, depress again brake pedal after the cut-through thing.Motor Vehicles in Emergency Brake Application easily produces sideslip, answers the settle brake pedal with the levelling vehicle body during sideslip.
3. Associated brake.Shifter bar is close the throttle in gear, utilizes engine speed to lead resistance and reduces the speed of a motor vehicle, depresses simultaneously brake pedal and makes wheel braking, and this leading by driving engine hindered and method that car side brake is braked to slow down is called Associated brake.Associated brake uses morely normally travelling when need slowing down, the emphasis that should grasp is:, should in time change to a low gear, otherwise will accelerate to damage driving system lower than in this gear during speed of a motor vehicle minimum standard when the speed of a motor vehicle.
4. ask the braking of having a rest property.Ask that the braking of having a rest property is a kind of braking method that intermittently depresses with the loosen the brake pedal.Due to long-term descending, brake system easily produces high temperature when mountain driving, causes deceleration and stopping performance to reduce, and for preventing the brake system excess Temperature, chaufeur often uses intermittent braking method.In addition, Pneumatic braking device also can use quick intermittent braking because suction quantity is difficult for grasp.
Above embodiment is only unrestricted in order to the utility model to be described, although with reference to preferred embodiment, the utility model is had been described in detail, those of ordinary skill in the art is to be understood that, the utility model is modified or is equal to replacement, and not breaking away from spirit and scope of the present utility model, it all should be encompassed in the middle of claim scope of the present utility model.
