Abstract
The utility model discloses an emergent speed-down brake device, including a brake keep plate (1), a brake cushion (5) which shape corresponds to that of the brake keep plate (1) and is arranged on the bottom of the brake keep plate (1), the front end of the brake keep plate (1) is provided with a connecting arm (6), a rotating shaft (2) is fixed on one end head of the connecting arm (6), a rotating rod (3) is fixed on the rotating shaft (2), and the bottom of the rotating rod (3) is connected with an output end of an air pump (4). According to the utility model, by means of a structure of the brake keep plate driven by the air pump, the brake cushion arranged on the bottom of the brake keep plate is contacted with the tread of the vehicle wheel so as to brake. The utility model is an independent device and separated from the built-in brake device, may be used alone when the built-in brake device is fault, which improves safety and plays a function of emergent speed-down brake. The utility model has advantages of simple structure, convenient operation, and good use effect.
Description
Technical field
The utility model relates to a kind of brake gear, especially a kind of emergency decelerating brake gear.
Background technology
At present,, sloping road and bend often occur, and when on these highway sections, travelling, need often use brake in the comparatively changeable area of surface state.But brake failure occurs on these highway sections is very dangerous, though some auxiliary or standby brake gears are arranged now, because their inconvenient operation, and cause situation such as overturning after the use easily, so result of use is unsatisfactory.
The utility model content
The purpose of this utility model is: a kind of emergency decelerating brake gear is provided, it provides a standby brake gear, can play the effect of emergency decelerating brake under the situation of original brake failure, and this apparatus structure is simple, easy to operate, to overcome the deficiencies in the prior art.
The utility model is achieved in that the emergency decelerating brake gear, comprise the brake pressing plate, bottom at the brake pressing plate is provided with the braking rubber cushion, front end at the brake pressing plate is provided with connecting arm, on the termination of connecting arm, be fixed with rotating shaft, be fixed with bull stick in rotating shaft, the bottom of bull stick is connected with the mouth of an air pump.
Front end at connecting arm is connected with a pull back spring.
Bottom at the braking rubber cushion is provided with cylinder.
Bottom at the braking rubber cushion is provided with groove spaced apart.
On the connection location of brake pressing plate and braking rubber cushion, be provided with cooresponding screw, pass screw by bolt between brake pressing plate and the braking rubber cushion and connect.
Owing to adopted technique scheme, compared with prior art, the utility model adopts air pump to promote the structure of brake pressing plate, utilizes the braking rubber cushion that is installed in brake pressing plate bottom to contact with the tyre surface of wheel, to realize the purpose of braking.This device is an independent device of installing, and separates with original brake gear, can use separately after the brake gear of reason goes wrong, and has improved safety, has played the purpose of emergency decelerating brake.The utility model is simple in structure, and is easy to operate, and result of use is good.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model;
Accompanying drawing 2 is the structural representation of braking rubber cushion.
The specific embodiment
Embodiment of the present utility model: the structure of emergency decelerating brake gear as shown in Figure 1, the employing steel plate processes the brake pressing plate 1 and connecting arm 6 that is connected as a single entity, and make block-shaped and brake pressing plate 1 a cooresponding braking rubber cushion 5, groove 9 is produced in the bottom of braking rubber cushion 5, and with a cylinder 8 stick into the braking rubber cushion 5 the bottom, on the connection location of brake pressing plate 1 and braking rubber cushion 5, set out cooresponding screw 11, pass the screw 11 of braking rubber cushion 5 and brake pressing plate 1 from the side with bolt, braking rubber cushion 5 is fixed on the bottom of brake pressing plate 1, to be convenient for changing braking rubber cushion 5, rotating shaft 2 of welding on the connecting arm 6 of brake pressing plate 1 then, connecting arm 6 is fixed in the rotating shaft 2, can rotate with rotating shaft 2, on the rotating shaft 2 close parts of right-hand member head, weld a fixing bull stick 3, and the bottom of bull stick 3 and the mouth of air pump 4 are coupled together.Front end at connecting arm 6 is connected with a pull back spring 7.
In use, emergency decelerating brake gear of the present utility model is installed on the car beam of tire top in the left and right sides behind the automobile, and a storage tank 14 is installed on automobile, storage tank 14 drives inflation pump by automotive engine and carries out gas storage, air pump 4 and the breather pipe 12 of storage tank 14 by a band valve 13 are coupled together, valve 13 is inserted the control corresponding device in operator's compartment, and display lamp is installed on control setup is represented mode of operation; When needs use this emergency decelerating brake gear, by the switch of in operator's compartment, pressing control setup the valve 13 of breather pipe 12 is opened, storage tank 14 provides source of the gas in air pump 4, the output shaft of air pump 4 is ejected forward, thereby promotion bull stick 3 drives rotating shaft 2 and rotates, the connecting arm 6 that is fixed in the rotating shaft 2 also just together rotates thereupon, makes brake pressing plate 1 touch the tyre surface 10 of wheel downwards, to play the effect of braking; After finishing using, valve 13 is closed, connecting arm 6 is rotated, thereby the pressing plate 1 that will brake retract original position.Usually the decorative pattern owing to tyre surface 10 makes contact surface uneven, when braking rubber cushion 5 and tyre surface 10 contacts, can produce vibrations, influence braking effect, therefore in the bottom of braking rubber cushion 5 cylinder 8 is set and solves this problem, the vibrations that produced when braking rubber cushion 5 is contacted with the wheel tyre surface are absorbed by the rotation of cylinder 8 buffering, to reduce the vibrations that produce, improve braking effect.And owing in braking rubber cushion 5 and tyre surface 10 contact frictions, can produce a large amount of heats, therefore offer groove 9 to increase the circulation of air, reduce the heat that produces because of friction in the bottom of braking rubber cushion 5.
