Abstract
The utility model discloses an emergency brake for a large-sized automobile. The emergency brake comprises a horizontal connecting rod, a release lever, a control hook and a braking body, wherein the release lever is arranged at the left end of the connecting rod, and is hinged with the connecting rod; the control hook is connected to the right end of the connecting rod; the braking body is arranged between the connecting rod and back wheel tires on both sides, and is provided with a braking body occlusal surface which is tightly attached to the outer outline surface of each back wheel tire during emergency braking and a braking body friction surface which is tightly attached to the ground during emergency braking; the braking body occlusal surface is matched with the outer outline surface of a tire; and the control hook is used for separating the braking body occlusal surface from the outer outline surface of the tire under non-braking condition. The emergency brake specially aims at emergency condition of failure in braking by cut-in speed reduction after a brake of a large-sized automobile fails, has a simple structure, and is safe and reliable; checking braking can be performed without using power of a vehicle or any external object; and the aim of performing checking braking can be fulfilled once braking of the vehicle fails, so that traffic accidents caused by braking failure are avoided.
Description
Technical field
The utility model relates to a kind of full-sized car accident brake.
Background technology
We see the traffic accident that some full-sized cars take place on the highway of being everlasting or in the news report, and personal casualty that accident causes and financial losses are often very serious.Find that according to the study in these accidents, majority is because brake failure causes.Up to the present, the full-sized car after the brake failure can only be taked to rob retaining basically and slow down, wipes method brakings such as extension, rear-end impact, but consequence is very serious often.
The utility model content
The purpose of this utility model is at above-mentioned situation, design one cover is specially at after the full-sized car brake failure, rob that retaining slows down also can't glancing impact, need be by simple, the failure-free accident brake of the mechanical control of the power of vehicle itself or foreign object brake snub, so that vehicle is in case discharge accident brake as early as possible after finding brake failure, reach the purpose of brake snub.
The purpose of this utility model realizes by following technical proposals:
A kind of full-sized car accident brake, comprise trigger bar, the connecting rod right-hand member bonded assembly control hook of connecting rod, connecting rod left end and the rod hinge connection of level and be arranged on connecting rod and the both sides rear tire between brake body, the brake body occlusal surface that described brake body has when emergency braking and described rear tire outer surface is adjacent to and when emergency braking, be adjacent to ground-surface brake body friction face, described brake body occlusal surface cooperates with the tire outer surface, and described control is hooked in and makes the brake body occlusal surface break away from the tire outer surface under the non-braking situation.
As optimal way, described brake body inside is provided with and makes control be hooked in the pocket for the punch head that hooks brake body under the non-braking situation.
As optimal way, described brake body occlusal surface is the occlusal surface with great friction coefficient.
As optimal way, described brake body friction face is the friction face with great friction coefficient.
As optimal way, it is characterized in that: described brake body is leg-of-mutton cube.
Principle of work of the present utility model: the control hook lock is lived brake body and is made the occlusal surface of brake body break away from the tire outer surface, makes the friction face of brake body break away from ground under non-braking situation, does not play brake action; When the needs emergency braking, in operator's compartment, pull trigger bar, drivening rod and control hook level travel forward, make brake body break away from the control hook, the brake body of disengaging control hook is owing to the effect of gravity falls immediately, the brake body occlusal surface acutely rubs with tire outer surface closed contact and generation immediately, under strong pressure, violent friction takes place in brake body friction face and ground, thereby forces the car deceleration braking.
The beneficial effects of the utility model: the utility model specially at after the full-sized car brake failure, rob retaining slow down also can't glancing impact emergency situation, need be by the power or the foreign object brake snub of vehicle itself, simple in structure, safe and reliable, in a single day vehicle finds can reach after the brake failure purpose of brake snub, avoids the traffic accident that takes place because of brake failure.
Description of drawings
Fig. 1 is a scheme drawing of the present utility model.
Fig. 2 is the schematic perspective view of brake body among Fig. 1.
Among the figure, 1 is trigger bar, and 2 is connecting rod, and 3 are the control hook, and 4 is brake body, and 5 is the brake body occlusal surface, and 6 is the brake body friction face, and 7 is pocket for the punch head.
The specific embodiment
Below in conjunction with specific embodiments and the drawings the utility model is further described.
As shown in Figure 1, a kind of full-sized car accident brake, the connecting rod 2 that comprises level, the trigger bar 1 of connecting rod left end and rod hinge connection, connecting rod right-hand member bonded assembly control hook 3, and be arranged on brake body 4 between connecting rod and the both sides rear tire, described brake body 4 is leg-of-mutton cube, the brake body occlusal surface 5 that described brake body has when emergency braking and described rear tire outer surface is adjacent to, and when emergency braking, be adjacent to ground-surface brake body friction face 6, described brake body occlusal surface 5 cooperates with the tire outer surface, control hook 3 makes the occlusal surface 5 of brake body break away from the tire outer surface under non-braking situation, brake body occlusal surface 5 is for having the occlusal surface of great friction coefficient, brake body friction face 6 is for having the friction face of great friction coefficient, wheel periderm as usual, or the brake rubber block material all has great friction coefficient, and brake body 4 inside are provided with and make control be hooked in the pocket for the punch head 7 that hooks brake body under the non-braking situation.
Principle of work of the present utility model: control hook 3 pinning brake bodies 4 make brake body occlusal surface 5 break away from the tire outer surfaces, make brake body friction face 6 break away from ground under non-braking situation, do not play brake action; When the needs emergency braking, in operator's compartment, pull trigger bar 1, drivening rod 2 and control hook 3 levels travel forward, make brake body 4 break away from the control hook, the brake body 4 of disengaging control hook 3 is owing to the effect of gravity falls immediately, brake body occlusal surface 5 acutely rubs with tire outer surface closed contact and generation immediately, under strong pressure, violent friction takes place with ground in brake body friction face 6, thereby forces the car deceleration braking.
The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
