Abstract
The invention relates to an automobile emergency braking and stoppage boosting device, which is an automobile active safety device. The device consists of a fixed arm, a fixed arm shaft, a telescopic arm, a sliding axle pin, a wedge block, a wedge block axle pin, a steel wire rope, a pulley, a compression spring, a compression spring seat, a roll shaft, and an electromagnetic clutch type steel wire rope reeling device; and the device is arranged on an automobile frame close to the front end of a rear wheel of the automobile. When the automobile is in normal driving, the device is positioned in a furling standby state; when the automobile is in emergency braking, the device can be rapidly opened, and the wedge block at the front end is instantaneously inserted into the front edge of the rear wheel of the automobile; therefore, the wedge block pressed under the front edge of the rear wheel of the automobile increases the area of contact friction between the automobile and the road, and increases the friction resistance between the automobile and the road, so that the braking distance of the automobile is shortened and the automobile is stopped as soon as possible.
Description
Technical field
The present invention relates to a kind of stop assisting device of automobile emergency glancing impact.
Background technology
At present, automobile main roller tire and ground-surface friction drag when emergency braking stops automobile.And the size of friction drag depends primarily on tire and ground-surface contact friction area and tire perpendicular to ground-surface pressure.Because the tire quantity of automobile is fixed number, tire and ground-surface contact friction area substantially also are fixed numbers.In case of emergency will shorten the stopping distance of automobile, automobile is stopped, key is to increase automobile automobile and ground-surface contact friction area when emergency braking.
Summary of the invention
Technical matters to be solved by this invention is: a kind of emergency braking stop assisting device of automobile that can increase automobile and road surface contact friction area at the automobile emergency glancing impact is provided.
The present invention solves the problems of the technologies described above the technical scheme that is adopted:
On automobile chassis frame, emergency braking stop assisting device of automobile is installed near the automobile back wheel front end.This device is in and packs up armed state during automobile normal running, when the automobile emergency glancing impact, this device will be opened rapidly, under its front end voussoir moment insertion automobile back wheel leading edge, the voussoir that is crushed on like this under the automobile back wheel leading edge has increased automobile and ground-surface contact friction area, strengthened automobile and ground-surface friction drag, will shorten the stopping distance of automobile like this, automobile is stopped as early as possible.
Emergency braking stop assisting device of automobile is by fixed arm, fixedly arm axle, telescopic boom, slip pivot pin, voussoir, voussoir pivot pin, steel rope, pulley, compression spring, compression spring seat, roll shaft, electromagnetic clutch type steel rope roll-up apparatus are formed.
Description of drawings
Below in conjunction with accompanying drawing emergency braking stop assisting device of automobile is described further.
Front view when Fig. 1 is the emergency braking stop assisting device of automobile armed state;
Right elevation when Fig. 2 is the emergency braking stop assisting device of automobile armed state;
Front view when Fig. 3 is the emergency braking stop assisting device of automobile emergency braking;
Fig. 4 is the birds-eye view of voussoir;
Among the figure, 1-vehicle frame, 2-automobile back wheel, 3-fixed arm, 4-fixedly arm axles, 5-steel rope, 6-electromagnetic clutch type steel rope roll-up apparatus, 7-screw, 8-slip pivot pin, 9-telescopic boom, 10-voussoir, 11-voussoir pivot pin, 12-roll shaft, 13-spring fixed seat, 14-compression spring, 15-pulley, 16-nut.
The specific embodiment
Shown in Figure 1, fixed arm 3 is installed on the vehicle frame 1 and by nut 16 by fixing arm axle 4 and is fixed; Telescopic boom 9 one ends can slide up and down along the fluting in the middle of the fixed arm 3 in the middle of the fixed arm 3 by slip pivot pin 8, and the other end is connected with voussoir 10 by voussoir pivot pin 11; 5 one of two steel ropes are connected with voussoir 10, and the other end is connected with the electromagnetic clutch type steel rope roll-up apparatus 6 that is fixed on screw 7 on the vehicle frame 1 through the pulley 15 that is installed on the fixing arm axle 4.13 1 crossbeams that pass on the fixed arm 3 of three spring fixed seats, other end are pressed in fixedly on the pivot pin 4, and its pressure comes from the compression spring 14 that is set in wherein.Be being connected of fixed arm 3 and fixing pivot pin 4 to realize by the upper end axial trough of fixed arm 3.
Shown in Figure 1 is the shape of emergency braking stop assisting device of automobile when being ready.This is that electromagnetic clutch type steel rope roll-up apparatus 6 passes through Wound steel rope 5 with voussoir 10 pull-ups, and voussoir 10 promotes the slip pivot pin 8 of telescopic booms 9 upper ends and slot upwards slip up to limiting the state that the position forms in the middle of fixed arm 3 by voussoir pivot pin 11.
Shown in Figure 2 is the state of emergency braking stop assisting device of automobile under automobile emergency braking situation.When the driver in case of emergency fiercely steps on brake pedal, to touch the emergency braking source switch and make 6 energisings of electromagnetic clutch type steel rope roll-up apparatus, the magnetic clutch that moment opens wherein discharges steel rope 5, drives telescopic boom 9 at the effect lower wedge block 10 from gravity like this and slides rapidly along middle fluting of fixed arm 3.When voussoir 10 was fallen on the road surface, under the fast leading edge that is crushed on automobile back wheel 2, compression spring 14 played certain buffer action.Because voussoir 10 is connected with vehicle frame 1 by telescopic boom 9, fixed arm 3, automobile back wheel 2 can not be crossed voussoir 10, and can only give voussoir 10 with the force of inertia and the weight transfer of automobile.Voussoir 10 produces violent friction with the ground-surface contact surface like this, thereby has strengthened automobile and ground-surface friction drag, make the stopping distance shortening of automobile, has improved the ability that automobile forfends collision, has improved ride safety of automobile, is a kind of automobile active safety device.
In order not influence the anti-lock effect of automobile back wheel 2, the roll shaft 12 that is installed on voussoir 10 and the telescopic boom 9 can make rolling touch between automobile back wheel 2 and voussoir 10 and the telescopic boom 9, can prevent that like this voussoir 10 and telescopic boom 9 from automobile back wheel 2 lockings, can effectively avoid automobile generation lateral sliding.Same consideration, the face that voussoir 10 contacts with the road surface is designed to shape as shown in Figure 4, left-right symmetric, as people's double-legged shape, its effect also is for fear of automobile generation lateral sliding.
