Abstract
The utility model relates to an automobile auxiliary brake device which belongs to machinery manufacturing technology. The automobile auxiliary brake device comprises a frame, a foot brake rod, a brake rod, a rotary shaft, a pneumatic-hydraulic telescopic cylinder and an electro-pneumatic control system, wherein the rotary shaft is arranged at the rear part of the frame and is in parallel with a rear axle; the brake rod is arranged on the rotary shaft; the middle part of the brake rod is hinged with a telescopic rod in the pneumatic-hydraulic telescopic cylinder; and one end of the brake rod is hinged with the rotary shaft, and the other end of the brake rod is a free end. According to the automobile auxiliary brake device, two fixed hinges are respectively arranged between the cylinder body of the pneumatic-hydraulic telescopic cylinder and the frame of the automobile, and between the rotary shaft and the brake rod, and a movable hinge is arranged between the middle of the brake rod and the telescopic rod, so that the telescopic rod in the pneumatic-hydraulic telescopic cylinder is enabled to push the brake rod to be close to the ground quickly and generate stronger friction force with the ground, and the deceleration and brake requirements under the condition of smaller frictional factor between the wheel of the automobile and the ground are accordingly realized. The automobile auxiliary brake device has the characteristics that the practicality is strong, and the deceleration and brake effects are good.
Description
Technical field
The utility model relates to a kind of auxiliary brake device for automobile, and particularly a kind of under snowfield, ice face environment, can immediately the deceleration or the auxiliary device of braking vehicle belongs to Machine Manufacturing Technology.
Background technology
On snowfield ice face traveling automobile can not slow down immediately because of skidding, the braking problem; Be that people pay close attention to and study and end the difficult problem that the present still can not effectively solve always; People once taked various measures for these years; As on tire, bundle anti-slipping chain, inlay anti-slop serrations, be provided with in the outside of tire dentation the anti-slip case of metal, adopt cushion block to land suchlike methods such as stopping the wheel slip; Make every effort to find the measure of a kind of practicable automobile preventing skid on snow, should affirm: these methods and measure hold water theoretically, also have certain skidproof effect in actual the use; But these methods all have different shortcoming and defect with measure; Such as: on tire, bundle anti-slipping chain, inlay anti-slop serrations and all be prone to make motor tire to damage, its structure of other certain methods and measure is too complicated again, and is special often not feasible for the limited automobile of compact conformation, space.Therefore, the vehicle skidproof, deceleration, the braking problem that solve under the snowfield ice noodles spare are still the emphasis problem that needs exploration and research.
Summary of the invention
The purpose of the utility model is to propose a kind of auxiliary brake device for automobile;, space features of limited compact to vehicle structure; Form simple kinematic mechanism through less member, solve the difficult problem that automobile can effectively slow down down, immediately brake at snowfield ice noodles spare.
To achieve the above object, the present utility model posed to the implementation of the following technical solution: An automobile auxiliary braking device, comprising a frame, the foot brake lever, brake lever, shaft, pneumatic and hydraulic telescopic cylinders, electro-pneumatic control system, after the frame Ministry set up parallel to the rear axle with a shaft, the shaft is provided with a brake lever and the brake lever in the middle of pneumatic and hydraulic telescopic rod telescopic cylinders hinged shaft brake lever hinged at one end and the other end is a free end; electro-pneumatic control system with limit switches, solenoid valve.The cylinder body of the moving telescoping cylinder of said gas-liquid is connected on the vehicle frame, and and vehicle frame between form the fixed hinge form of turning pair; The fixed hinge form of one end of said brake lever and the hinged formation turning pair of rotating shaft, the hinges form of the hinged formation turning pair of expansion link in the moving telescoping cylinder of middle part and gas-liquid; Rotating shaft is fixedly connected on the vehicle frame, and the axial line of rotating shaft and rear wheel pivot center line parallel; The cylinder body of the moving telescoping cylinder of gas-liquid is connected on the vehicle frame, and and vehicle frame between form the fixed hinge form of turning pair; The contact of travel switch is positioned near the bottom dead point end position of service brake bar.
The utility model is through two fixed hinge forms between moving telescoping cylinder cylinder body of gas-liquid and the automobile chassis frame, between rotating shaft and the brake lever and a hinges form between brake lever middle part and the expansion link; Make the expansion link promotion brake lever in the moving telescoping cylinder of gas-liquid immediately press to ground; And and ground between produce stronger friction force, thereby realize deceleration, the brake request under the less condition of friction coefficient between automotive wheels and the ground.
Compare with orthodox car deceleration, brake equipment; The useful contribution of the utility model is: practical, deceleration and braking effect are obvious; Be particularly suitable on the lorry of being with back axle, passenger vehicle, using, car also can use after suitably reequiping, and this device back vehicle appearance is installed is not had change.
Description of drawings
Accompanying drawing 1 is the structural principle scheme drawing of the utility model.
In accompanying drawing 1: 1 vehicle frame, 2 rotating shafts, 3 brake lever, 4 rear wheels, 5 snowfields ice face, 6 pneumatic telescoping cylinders, 7 bi-bit bi-pass solenoid directional control valves, 8 storage tanks, 9 air pumps, 10 service brake bars, 11 travel switches.
The specific embodiment
To dispose pneumatic telescoping cylinder is that example is described further the utility model:
Shown in accompanying drawing 1, the cylinder body of pneumatic telescoping cylinder 6 is connected on the vehicle frame 1 of automobile, and and vehicle frame 1 between form the fixed hinge form of turning pair; Rotating shaft 2 is fixedly connected on the vehicle frame 1, the axial line of rotating shaft 2 and rear wheel 4 pivot center line parallels; The fixed hinge form of one end of brake lever 3 and rotating shaft 2 hinged formation turning pairs, the hinges form of the hinged formation turning pair of expansion link in center and the pneumatic telescoping cylinder 6.The contact of travel switch 11 is positioned near the bottom dead point end position of operator's compartment service brake bar 10; High pressure gas in the pneumatic telescoping cylinder 6 are supplied with by storage tank 8, and the confession of storage tank 8 is died and realized by travel switch 11 commander's bi-bit bi-pass solenoid directional control valves 7 break-makes; Air pump 9 can replenish pressurized air to storage tank 8 at any time.
Traveling automobile need be slowed down or glancing impact on snowfield ice face 5; Step on service brake bar 10, depression stroke switch 11,7 energisings of travel switch 11 commander's bi-bit bi-pass solenoid directional control valves; High pressure gas in the storage tank 8 get in the inlet chamber of pneumatic telescoping cylinder 6; Promote expansion link in the pneumatic telescoping cylinder 6 and stretch out and depress brake lever 3, brake lever 32 is made clickwise around the shaft, the one of which end press snowfield ice face 5 and and snowfield ice face 5 between produce very strong friction force; Automobile kinetic energy in going is consumed on friction force, thereby realize the purpose of deceleration and braking.Unclamp service brake bar 10; Travel switch 11 is replied, 7 outages of bi-bit bi-pass solenoid directional control valve, and the air inlet road is closed, open on the return-air road; The inlet chamber of pneumatic telescoping cylinder and atmosphere pressure release; Spring or plug-in spring or the low-pressure air of preliminary filling in pneumatic telescoping cylinder bottom pre-installed in pneumatic telescoping cylinder 6 reset piston rod, and expansion link is regained, and brake lever 2 is returned to the state of lifting.
