Abstract
The utility model relates to an emergency braking device of an automobile, which is used in emergency situations when a severe collision is about to happen. The emergency braking device comprises a hydraulic cylinder, a rotating arm, a connecting rod shaft, a friction block clamp and a friction block; a cylindrical pin is fixed at the front end of a piston rod of the hydraulic cylinder and can perform relative motion in a straight groove on the left of the rotating arm; the middle part of the rotating arm is in running fit with a wheel axle of the automobile through a sleeve or a sliding bearing; the right end of the rotating arm is hinged with the fraction block through the connecting rod shaft; the fraction block clamp and the fraction block are connected through interference fit or screws; connecting rod shaft further connects the braking devices on the two sides of the wheel axle into a whole so as to increase the overall rigidity; the fraction block is a rubber block with a hollow air bag, and the teeth of a friction surface at the bottom of the fraction block are in the shape of a sawtooth or an embedded iron nail array; and the hydraulic cylinder is fixedly installed on a frame and is controlled through an electromagnetic valve and an emergency button on an instrument panel. The emergency braking device has the advantages of simple structure, convenience in manufacture and installation, good integral rigidity and large friction force.
Description
Technical field
The utility model relates to brake system of car, is specifically related to the standby brake equipment of a kind of automobile.
Background technology
In general, brake system of car comprises service brake device and holding brake device two cover independent device.Wherein the service brake device is that chaufeur is handled with pin, so claim " service brake " again; Holding brake device is that chaufeur is hand-operated, so claim " parking brake " again.But in real life, whole world every day is all in the traffic accident that car crash takes place.Mainly, poor stop untimely with overspeed of vehicle, overload, road is wet and slippery or reason such as icing causes brake or brake equipment inefficacy etc. are relevant for these.Therefore, a lot of people are arranged in the research of carrying out emergency brake device or standby brake equipment both at home and abroad, proposed many schemes, but up to the present, do not find actual applying as yet.
Summary of the invention
The purpose of this utility model is the deficiency that overcomes the above-mentioned background technology, provides a kind of practical automobile standby brake equipment, shortens stopping distance under emergency situation, prevents the collision case generation or alleviates the collision extent of injury.
The purpose of this utility model realizes with the following methods.The standby brake equipment of a kind of automobile, mainly formed by hydraulic ram, swivel arm, pitman shaft, friction shoe folder and friction shoe, the piston rod front end of hydraulic ram fixedly has a straight pin, this straight pin can do relative motion in the straight trough on the swivel arm left side, the swivel arm middle part is by lining or plain bearing and automotive axle normal-running fit, the swivel arm right-hand member is hinged by pitman shaft and friction shoe folder, and the friction shoe folder links to each other by interference fit or screw with friction shoe.Described pitman shaft also is connected as a single entity the brake equipment on vehicle bridge both sides, to strengthen integral rigidity.Described friction shoe is the hollow gasbag rubber block, and the teeth patterning of bottom friction face is serration or is embedded iron nail array (iron nail embeds in the rubber, and the match that is similar to a plurality of little iron nails is used at the bottom of the sports footwear, is mainly used in ice and snow road).Described hydraulic ram is fixedly mounted on the vehicle frame, controls by electromagnetic valve and the critical button that is installed on the facia board.
Characteristics of the present utility model and beneficial effect are: 1) simple in structure, be easy to make and install, and integral rigidity is good; 2) friction shoe adopts the hollow gasbag rubber structure, and elastic deformation is big, contains the uneven profile on road surface easily, and earth-catching property is good, and the impulsive force can cushion friction shoe and contact to earth the time; 3) teeth patterning of bottom friction face is serration or is embedded iron nail array, cooperates the hollow gasbag rubber structure, and the earth-catching property of friction shoe and friction force are further strengthened.
Description of drawings
Accompanying drawing 1 is front view of the present utility model, i.e. fundamental diagram; Accompanying drawing 2 is birds-eye view of the present utility model, i.e. main assembly figure; Accompanying drawing 3 is embedded iron nail array friction shoe scheme drawing of the present utility model.
The specific embodiment
Below with reference to accompanying drawing enforcement of the present utility model is described further.
The standby brake equipment of automobile described in the utility model, mainly formed by hydraulic ram 1, swivel arm 4, pitman shaft 7, friction shoe folder 8 and friction shoe 9, piston rod 2 front ends of hydraulic ram 1 fixedly have a straight pin 3, straight pin 3 can do relative motion in the straight trough on swivel arm 4 left sides, swivel arm 4 middle parts are by lining or plain bearing 5 and automotive axle 6 normal-running fiies, and swivel arm 4 right-hand members link to each other with friction shoe 9 by pitman shaft 7 and friction shoe folder 8.Pitman shaft 7 also is connected as a single entity the brake equipment on vehicle bridge both sides, to strengthen integral rigidity.Friction shoe 9 is the hollow gasbag rubber block, the teeth patterning of bottom friction face be serration (as shown in Figure 1, can be used for dry or wet and slippery road surface) or be embedded iron nail array (as shown in Figure 3, iron nail 10 embeds in the friction shoes 9, is mainly used in ice and snow road).Described hydraulic ram 1 is fixedly mounted on the vehicle frame, controls by electromagnetic valve and the critical button that is installed on the facia board.
When chaufeur when stepping on the normal row vehicle brake, estimation will occur pressing the critical button on the facia board immediately under the emergency situation of serious collision, starts the standby brake equipment of automobile.At this moment, piston rod 2 clockwise rotates around automobile back wheel vehicle bridge 6 by the straight pin 3 promotion swivel arms 4 of front end, and swivel arm 4 right-hand members contact with ground by pitman shaft 7 and friction shoe folder 8 compressing friction shoes 9.Thereby play the shortening stopping distance, prevent the effect that collision case takes place.
When the standby brake equipment of automobile was not activated, the bottom surface terrain clearance of friction shoe 9 should be greater than the terrain clearance of axle center shell lower end, to guarantee the traffic potential of automobile on bad road surface.
