Abstract
The utility model discloses a brake buffer device of vehicle, wherein a buffer plate is provided with a force component groove equipped with a vehicle chief shaft at one end and a limiting bolt hole vertical to the force component groove, one end of a limiting bolt is in the limiting bolt hole, while an outer end is provided with a return spring and connected with a drawing rod, another end of the drawing rod is connected with a brake bar, the upper end of the buffer plate is fixed on the chassis of vehicle. The buffer device of the utility model is arranged on the shaft of active wheels of vehicle, and force component groove is arranged on the buffer plate, therefore, when vehicle brakes in emergency, the pin shaft sealing the force component groove is opened, so the wheel shaft slides downwards along the force component groove, thereby dividing the forward force into upward and downward forces, reducing forward inertia force of vehicle, greatly shortening the forward distance after brake, and improving the assurance factor.
Description
Technical field:
The utility model relates to the brake of motor-driven vehicle device, relates in particular to the brake of motor-driven vehicle shock absorber.
Background technology:
At present, when self-propelled vehicle meets the emergency brake of extraordinary circumstances need, it is thrust forward one segment distance under the effect of force of inertia always, if the speed of a motor vehicle is very fast before this, will thrust forward just can stop for 100 meters, tend in this case get into an accident with the obstacle collision, jeopardize people's life, even can cause the great bodily injury accident of car crash, and bring misery for people's life, bring factor leading to social instability to society.In recent years, self-propelled vehicle manufacturer and numerous scientific and technical personnel, all seek can controlling machine the technical scheme of motor-car distance of thrust forward during in emergency brake, but be not resolved yet so far.
Goal of the invention:
The technical problems to be solved in the utility model provides a kind of shock absorber when brake of motor-driven vehicle, self-propelled vehicle is disperseed to the force of inertia of preshoot, and reach the distance that shortens thrust forward after the emergency brake.
The technical solution of the utility model is to realize like this, a kind of brake of motor-driven vehicle shock absorber, have the component groove on the dash plate, vehicle spindle is positioned at an end of component groove, be provided with limit pin hole perpendicular to the component groove, locating dowel pin one end is positioned at limit pin hole, and its outer end is provided with retracing spring, be connected with pull bar in this end termination that is provided with retracing spring, the other end of pull bar is connected on the brake lever; The upper end of described dash plate is connected and fixed on the motor-vehicle chassis.
Beneficial effect: the utility model is arranged at shock absorber on the axle of self-propelled vehicle driving wheel, dash plate is provided with the component groove, when the self-propelled vehicle emergency brake, the bearing pin of sealing component groove is opened, wheel shaft is glided along the component groove, thus with thrust forward power be decomposed into downwards, upward force, reduced self-propelled vehicle force of inertia forward, realized that self-propelled vehicle distance to preshoot after emergency brake shortens greatly than existing situation, has improved the safety of person vehicle coefficient.
Description of drawings:
Fig. 1 is the utility model coupled condition and partial schematic sectional view;
Fig. 2 is that pull bar is connected and working state schematic representation with brake gear.
The specific embodiment:
As shown in Figure 1, dash plate is provided with component groove 2, and be provided with the limit pin hole 4 vertical with component groove 2, main shaft 3 passes component groove 2, place an end of component groove 2, its horizontal surface should form angle a, i.e. 30 °-45 in component groove 2, as be used for little proud car angle a and then can be 35 ° of angles, dash plate 1 places the center (between two-wheeled) of main shaft 3.Still as shown in Figure 1, it is free-running fit that locating dowel pin 5 inserts behind the limit pin holes with main shaft 3, promptly allow main shaft 3 when spacing state, can freely rotate, the end, outer end of locating dowel pin 5 is provided with retracing spring 6, retracing spring 6 one ends are connected and fixed on the locating dowel pin hole wall, and the other end is connected and fixed on the locating dowel pin 5.As shown in Figure 1 and Figure 2, the termination, outer end of locating dowel pin 5 is connected with pull bar 7, and the other end of pull bar 7 is connected on the brake lever 8; Pull bar 7 is a unitized construction, is connected as a single entity by bearing pin.
As shown in Figure 1 and Figure 2, when self-propelled vehicle was in normal working, pull bar 7 was the state of Fig. 1 and Fig. 2 a; When self-propelled vehicle is done the brake of non-emergent state (brake gear is not floored), pull bar 7 is Fig. 2 b state, that is pull bar 7 is made displacement movement with this end of brake lever 8 bonded assemblys round bearing pin; When the self-propelled vehicle emergency brake, along with pull bar 8 continues to move downward,, thereby locating dowel pin 5 is pulled out (being that component groove 2 is opened) with the other end of pull bar 7 brake lever 8 that furthers, this moment, pull bar 7 was as Fig. 2 c state.After the emergency brake state was eliminated, under the effect of pull back spring 6, spacing lock 5, pull bar 7 and brake lever 8 were recovered state (cruising state) shown in Fig. 1 and Fig. 2 a.
When the self-propelled vehicle emergency brake, locating dowel pin 5 is pulled out (being that component groove 2 is opened), main shaft 3 glides along component groove 2, with thrust forward power be decomposed into downwards, upward force, thereby reduced the force of inertia of thrust forward, effectively shortened distance, and when vehicle stopped, main shaft 3 by gravitys automatically reset immediately to preshoot.
