comparative approach 1

[0076] The difference between the analysis and comparison scheme 1 and the technical scheme 2 is:

[0077] Option 1, foot brake master cylinder for driving: on the basis of the original set of foot brake devices for driving controlled by the right foot, an additional set of foot brakes for driving controlled by the left or right foot is installed. Device: Its brake master cylinder and its corresponding brake pedals, supporting parts, etc., are additionally installed in the cab, driving position, and in the activity area of ​​the driver's left or right foot; The foot brake cylinder is connected with the driving foot brake master cylinder and possible various brake auxiliary system components that are additionally installed in the cab, driving position, and the driver's left or right foot activity area to form a A vehicle has at the same time more than one set of foot brake master cylinders for driving to control more than one set of completely independent or partially independe...

Embodiment 1

[0082] For cars with manual transmission: in the driving position of the car cab, on the left side of the clutch pedal 3 in the driver's left foot activity area, a foot brake master cylinder for driving and its corresponding additional braking system controlled by the driver's left foot are additionally set. Pedal 2, such as figure 1 .

[0083] For automobiles with drum-type driving foot brakes: on the outside edge of the opening end of the brake drum 11, an additional annular metal brake disc 9 is formed on a brake drum 11, and a brake disc 9 is additionally provided The drum-disc combined type driving foot brake that combines two into one; the drum-disc combined type driving foot brake is integrally cast during production; on the basis of the length of the original brake drum 11, in order to give the brake disc 9 enough To set up space and avoid possible contact friction between the brake disc 9 and the tire during driving, the overall length of the brake drum 11 should be ...

Embodiment 2

[0087] The brake pipeline in the dual brake system structure of the present embodiment uses liquid as the transmission drive medium, the original driving foot brake device of the automobile, wherein the original brake master cylinder 18, the original brake pedal 4 and its The corresponding and necessary supporting parts are set in the driving position of the car cab and the activity area of ​​the driver's right foot, and are controlled by the driver's right foot; the original brake pipeline 12 is combined with the front and rear four drum discs. The foot brake for driving, four of the drum brakes, the brake pipeline of the brake cylinder 10, and various brake auxiliary system components that may be connected to form a relatively independent foot brake device for driving .

[0088] The additional foot brake device for driving, in which the additional brake master cylinder 21, the additional brake pedal 2 and their corresponding and necessary supporting parts, are all additional...

Abstract

The invention discloses a foot brake for driving and a double brake system. The foot brake for driving is a drum-disc combined type driving foot brake or a disc multi-clamp type driving foot brake; the drum-disc combined type driving foot brake is used for braking On the outside of the edge of the drum opening, there is an additional ring-shaped metal brake disc, and the brake disc is equipped with one or more sets of disc brakes, including brake cylinders and brake calipers; a disc multi-caliper driving foot brake It is a brake wheel cylinder and a brake caliper in which one or more sets of disc brakes are additionally installed on the brake disc. This brake overcomes the problems of long braking distance or brake failure. The double brake system adopts an additional driving foot brake device with a backup function on the car. The additional brake device can obtain the same braking device as the original brake device of the car. Braking efficiency with comparable braking force can minimize and avoid possible traffic accident tragedies, and effectively protect people's lives and property.

Description

technical field [0001] The invention relates to the field of foot brakes for driving automobiles, more specifically, to a foot brake and a double brake system suitable for heavy-loaded freight cars and large and medium-sized passenger cars with many passengers. Background technique [0002] So far, cars are generally only equipped with a foot brake system for driving and a hand brake system for parking. When the car is braking, it needs a certain braking distance; when the car is braking, the foot brake system of the car may also fail. [0003] The reasons that affect the length of the foot braking distance of the automobile, or cause the failure of the foot braking system of the automobile are complex and diverse. At present, the main braking method of foot brakes for driving is still mainly friction braking; the classification of its brakes can be roughly divided into two categories: drum brakes and disc brakes; their foot brakes for driving are generally The pump, the b...
