Problems solved by technology

To a certain extent, a good effect cannot be achieved. The existing standard brake master cylinder, when heavy-loaded, cannot achieve safe driving to a certain extent due to the large gas stroke and long braking distance. In order to improve the heavy-duty braking effect, people Invented a powerful brake master cylinder, but this technology also has disadvantages. Because the effect is too strong, when an empty vehicle is used, it will often cause a sudden lockup, which will cause rear-end collision and slippage of the vehicle behind, which is not suitable. It is used in rainy and snowy weather; in addition, the above two technologies also have a common shortcoming. Due to the deviation in the response of the front and rear wheels, the front wheels brake early and the rear wheels brake late. OK, so well bonded and responsive; the rear wheel is the opposite
The shortcomings of the above two technologies all have unsafe factors and unnecessary tire wear, which will cause major car accidents in severe cases
[0003] Chinese patent ZL99208974 proposes an automobile brake valve, and Chinese patent ZL200420061352 proposes an automobile brake valve, both of which adjust the opening of the valve, which improves the braking force and braking effect to a certain extent, but does not Did not fundamentally solve the above problems

Embodiment 1

[0025] Embodiment one: see Figure 1 to Figure 5 , in the figure, 1-brake lever, 2-return spring, 3-pad, 4-cassette, 5-anti-skid pad, 6-shaft sleeve, 7-rotating shaft, 8-pedal panel, 9-adjusting nut, 10 -Lock nut, 11-Fixer, 12-Touch switch, 13-Fixed nut, 14-Contact push rod, 15-Insulation shell, 16-Insulation cover, 17-Insulation push rod, 18-Connection plate and contact piece , 19-insulating backing plate, 20-pack cover, 21-flat pad, 22-push rod bushing, 23-guide plate.

[0026] The lower surface of the integral pedal 8 is rotationally connected with a fixed frame 11 through the rotating shaft 7 and the axle sleeve 6, and the axes of the rotating shaft 7 and the axle sleeve 6 deviate from the center of the width direction of the integral pedal panel 8, and the rotating shaft 7 and the axle sleeve The axis of 6 is obliquely intersected with the central line of the width direction of the integral pedal panel 8 (or orthogonally can also be used), and the fixed frame 11 is conne...

Embodiment 2

[0030] Embodiment two: see Image 6 , Figure 7 with Figure 8 , the same numbers in the figure represent basically the same meaning, and the similarities will not be repeated. The difference is that the structure of the brake lever 1 is different, it is located outside the integral pedal panel 8, and the integral pedal panel 8 and the fixed A return spring 2 is arranged between the frames, and the specific structures of the fixed frames 11 are not the same, but their functions are the same. This embodiment is suitable for heavy trucks.

Abstract

The invention discloses an integrated emergency brake pedal, comprising an integrated pedal panel. The lower surface of the integrated pedal panel is rotatablely connected with a fixed frame by a rotary shaft and a shaft sleeve; furthermore, the axis line of the rotary shaft and the shaft sleeve is biased with the center of the width direction of the integrated pedal panel; the fixed frame is connected with a brake rod; furthermore, the fixed frame is provided with a contact switch; the contact of the contact switch is corresponding to the integrated pedal panel at one side of the rotary shaftand the shaft sleeve; a recovery spring is arranged between the integrated pedal panel at the other side of the rotary shaft and the shaft sleeve and the fixed frame or the brake rod; the integratedpedal panel can rotate around the rotary shaft and the shaft sleeve and get the contact switch through. The invention has the advantages of simple structure, reasonable design, integrating brake and control electromagnetic valve switch into a whole, being convenient for operation and wide applicable range, which is especially suitable for DongFeng series vehicles and other heavy trucks and has good social and economic benefits after generalization.

Description

1. Technical field: [0001] The invention relates to a brake pedal, in particular to an integrated emergency brake pedal. 2. Background technology: [0002] The working principle of the existing heavy-duty vehicle braking system has disadvantages. To a certain extent, the good effect cannot be achieved. The existing standard brake master cylinder, when heavy-loaded, cannot achieve safe driving to a certain extent due to the large air stroke and the long braking distance. In order to improve the heavy-duty braking effect, people Invented a powerful brake master cylinder, but this technology also has disadvantages. Because the effect is too strong, when an empty vehicle is used, it will often cause a sudden lockup, which will cause rear-end collision and slippage of the vehicle behind, which is not suitable It is used in rainy and snowy weather; in addition, the above two technologies also have a common shortcoming. Due to the deviation in the response of the front and rear wh...
