Description
Technical field
The utility model relates to a kind of automobile emergency brake field, particularly relates to a kind of braking automobile auxiliary device.
Background technology
In today of traffic develop rapidly, one of important tool of communications and transportation automobile is being brought into play important effect in intense market competition.But the traffic accident that thereupon brings also frequently takes place.The overwhelming majority is because of speed of a motor vehicle height in these traffic accidents, the automobile brake distance, especially at running on expressway, when in case of emergency, even taked the emergency brake measure, automobile also can not in time be braked because of braking factors such as back coasting distance length, causes the generation of major traffic accidents.Application number is 91230316.6, name is called the innovation and creation of " braking automobile auxiliary device ", though improved braking performance of automobile, shortened the cunning after the brake towards distance, but because be provided with spring in the friction member, so the friction member contacts not thoroughly with ground-surface during emergency brake, the auxiliaring effect that brakes is undesirable.
Summary of the invention
The purpose of this utility model is to remedy the deficiencies in the prior art, when providing a kind of the use for people and the brake system of automobile use synchronously, make automobile produce extra friction, the cunning that shortens brake improves the braking automobile auxiliary device of automobile brake perfrmance towards distance effectively.
The purpose of this utility model is achieved through the following technical solutions.
Braking automobile auxiliary device of the present utility model, comprise Hydraulic Pump, weight arm, the friction member, wherein the upper end of weight arm is hinged on the vehicle frame, the centre of weight arm is connected with the lower end of Hydraulic Pump, the upper end of Hydraulic Pump is movably connected on the vehicle frame, Hydraulic Pump is connected with hydraulic pipe, the other end of hydraulic pipe is connected with master cylinder, the lower end of described weight arm is hinged with the friction member, one end of friction member and an end of pull bar are hinged, the other end and the weight arm of pull bar are hinged, the friction member the other end be provided with retracting cylinder and with the friction member be one, binding fixing on the outside axle tube of semiaxis is provided with the location retracting cylinder shell that is enclosed within retracting cylinder, is provided with retracing spring between described retracting cylinder shell and the friction member.
Also be provided with slideway on the described binding, the retracting cylinder shell on this slideway can about be free to slide.
Described friction member bottom is provided with the high compounded rubber friction body of coefficient of friction.
The lower end of described weight arm and the upper end of pull bar are provided with sliding tray.
The utility model has the advantages that simple and reasonable, safety durable, cost are low, and car body is rapidly stopped, prolong and bump against spacing and reach crashproof purpose.
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a running condition scheme drawing of the present utility model.
The specific embodiment
As Fig. 1, shown in Figure 2, the braking automobile auxiliary device comprises Hydraulic Pump, weight arm, the friction member, wherein the upper end of weight arm 1 is hinged on the vehicle frame 4, weight arm 1 is connected with the lower end of Hydraulic Pump 6, the upper end of Hydraulic Pump 6 is movably connected on the vehicle frame 4, Hydraulic Pump 6 is connected with hydraulic pipe 7, the other end of hydraulic pipe 7 is connected with brake pump, be a switch to be installed in the operator's compartment or a special-purpose control pedal is installed, be connected with described hydraulic pipe 7, control this device state that enters or deactivate, the position of described special-purpose control pedal can be presented with former brake pedal, the following arrangement, in the ordinary course of things, only with following former brake pedal, when emergency situation, can with on, following two pedals depress simultaneously, pulling assist brake switch when perhaps stepping on former brake is worked two cover brake gears simultaneously.
The lower end of described weight arm 1 is hinged with friction member 3, and during the brake of friction member 3 point of discontinuitys and road surface is if from as if the state of reaching, synchronous working with tire 15 when sudden stop; One end of friction member 3 and an end of pull bar 2 are hinged, the other end of pull bar 2 and weight arm 1 are hinged, the friction member 3 the other end be provided with retracting cylinder 5 and with the friction member be one, the binding 12 of the outside axle tube 11 of semiaxis 10 is provided with the location retracting cylinder shell 8 that is enclosed within retracting cylinder (5), is provided with retracing spring 9 between retracting cylinder shell 8 and the friction member 3.
When sudden stop, pulling assist brake switch or depress special-purpose control pedal when depressing former brake pedal, pass to the brake weight of Hydraulic Pump 6 by hydraulic pipe 7 and push weight arm 1 to ground, the retracting cylinder shell also will move in the horizontal direction with on the vertical direction, be that the retracting cylinder shell slides to semiaxis 10 directions on slideway 13, be fixed on the retracting cylinder 5 direction motion earthward on the friction member 3, the sliding tray 17 that the sliding tray 16 that the lower end of weight arm 1 is provided with and the upper end of pull bar 2 are provided with is also in the effect lower slider of brake weight, make the member 3 that rubs make the friction body 14 of friction member bottom contact and produce extra friction force with ground, this friction body 14 can be made of the high rubber of coefficients of friction such as used tire, the spacing of will braking is dwindled, and reaches the purpose of emergency braking.After reaching the purpose of emergency braking, when automobile continued to move forwards or backwards, under the effect of the recovery of the reset mode of brake pedal and retracing spring 13, friction member 3 returned to the state that previous status is promptly left with ground.
Owing to the difference of vehicle changes connection mode and shape, its principle inconvenience still belongs to protection domain of the present utility model.
