Abstract
A linkage brake device of an electric vehicle comprises a bottom plate, a differential transmission, a brake pedal and a push rod, wherein the differential transmission, the brake pedal and the push rod are assembled on the bottom plate, a swing rod fixedly provided with the pedal and a swing arm hinged to one end of the push rod are respectively assembled on a supporting seat of the bottom plate through a rotating shaft, the end part of the swing rod is hinged to a sliding rod of the differential transmission through a connecting plate, and the other end of an adjustable push rod is hinged to a pull rod of a. The linkage brake device overcomes the defects of the existing linkage brake device, and can easily adjust the positions of electric, pneumatic or hydraulic brake regions respectively to achieve the optimal brake effect, ensure the driving safety and reduce the labor intensity of operators.
Description
The utility model relates to a kind of braking device for vehicle, the battery-driven car linkage braking device of particularly a kind of electricity, gas or fluid pressure linkage.
At present, existing car brakeing mostly is single dynamic brake; Battery-driven car also has the brake equipment that adopts electricity, gas or fluid pressure linkage, but its complex structure, the electric braking parts of this device and gas or hydraulic braking parts are arranged to one, with electric braking differential speed variator slide bar pivotally attached brake pedal be in the same place with brake activation valve pull bar pivotally attached gas or liquid brake push rod direct connection, when brake pedal presses down, brake push rod moves immediately, the therefore difficult interval position of adjusting between the two of mutual braking, and it is very inconvenient to make it to coordinate to reach optimum braking effect.So not only increased the work capacity of operating personal, time-consuming, effort, and be difficult to reach optimum braking effect.
The purpose of this utility model provides a kind of improved battery-driven car linkage braking device, it has overcome the shortcoming of above-mentioned linkage braking device, can be easy to adjust respectively the interval position of electricity, gas or hydraulic braking to reach best braking effect, guarantee traffic safety, alleviated labor intensity of operating personnel.
The purpose of this utility model is achieved in that this device comprises base plate and assembles differential speed variator, brake pedal, push rod on it, the swing arm that wherein installs the fork of pedal, hinged push rod one end utilizes rotating shaft to be assembled on the supporting base of base plate respectively, swing link end part is hinged by the slide bar of connecting panel and differential speed variator, and the other end of adjustable push rod is hinged on the pull bar of brake activation valve.
Because the fork of this device brake pedal and the swing arm rigging position of push rod break away from mutually, are not directly to be connected, but utilize rotating shaft to be assembled on separately the supporting base.When pedal depression, fork at first rotates around the axis, and moves slide bar by connecting panel and realizes that electric braking, pedal go to when contact with swing arm, presses swing arm and sways, and the pull bar that promotes push rod drive brake activation valve moves forward into promoting the circulation of qi braking or hydraulic braking.Because of pedal directly is not connected with push rod, so can be easy to adjust respectively the interval position of the braking of electricity, gas or hydraulic pressure, reaching best braking effect, thereby guaranteed traffic safety, alleviated labor intensity of operating personnel simultaneously.
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is a kind of concrete structure scheme drawing of the present utility model.
Fig. 2 is the lateral plan of Fig. 1.
Describe concrete structure of the present utility model in detail according to Fig. 1-2.This device comprises base plate 6, be assembled in the differential speed variator 14 of base plate 6 bottoms and guard shield, and (Fig. 2 is the structural representation of laying down behind the guard shield) is assembled in parts such as the supporting base 3,5 on base plate 6 tops, the brake pedal 1 that is fixed with fork 2, the adjustable push rod 7 of braking, swing arm 4, spacing screw rod 9.Wherein the fork 2 of brake pedal 1 utilizes rotating shaft to be assembled on the supporting base 3, the hinged adjustable push rod 7 in swing arm 4 upper ends, and its lower end utilizes rotating shaft to be assembled on the supporting base 5. Supporting base 3,5 can be assembled in respectively on the base plate 6, also can be linked to be overall package on base plate 6.The end of fork 2 is hinged with the slide bar 12 of differential speed variator 14 by connecting panel 11, and the other end of adjustable push rod 7 is hinged on the pull bar 13 of brake activation valve.Install the projection 8 that can contact with swing arm on pedal 1, fork 2 lower ends that are assembled on the supporting base 3 of base plate 6 utilize retracing spring 10 to be stretched on the permanent seat 15 of base plate 6 bottoms.Variation for convenient adjustable push rod 7 axial distances is provided with length adjuster in its lower end.
During use, when brake pedal is pressed in for 1 time in α 1 angular range, the rotating shaft of fork 2 on supporting base 3 rotated, realize electric braking by the slide bar 12 of connecting panel 11 pulling differential speed variators 14.When pedal 1 continues to press down, when surpassing α 1 angular range, the projection 8 on the pedal 1 presses the rotating shaft of swing arm 4 on supporting base 5 and rotates, and drives push rod 7 and moves, and the pull bar 13 that drives brake activation valve carries out gas or hydraulic braking.Pedal 1 drives swing arm 4 and implements electricity, gas or fluid pressure linkage braking in α 2 angular range, and when pedal 1 was depressed into spacing screw rod 9, the interlock braking reached the braking effect of the best.Unclamp pedal 1, under the effect of retracing spring 10, go back to the initial position, swing arm 4 simultaneously also goes back to the initial position, waits for braking next time.
