Abstract

The invention relates to a spare brake device for a car, which is used for the emergency that severe collision is likely to occur. The spare brake device consists of a hydraulic oil cylinder, a rotary arm, a connecting lever shaft, a friction block clamp and a friction block, wherein the front end of the hydraulic oil cylinder is fixedly provided with a cylindrical pin, the cylindrical pin can make relatively movement inside a straight groove on the left side of the rotary arm, the middle part of the rotary arm is matched with a car axle through a bushing or a slide bearing in a rotating way, the right end of the rotary arm is hinged with the friction block clamp through the connecting leverl shaft, and the friction block clamp is in interference fit with the friction block or connected with the friction block through a screw. Two brake devices on two sides of an axle are connected into a whole through the connecting lever shaft, so that the overall rigidness can be enhanced. The hydraulic oil cylinder is fixedly installed on a frame and controlled through an electromagnetic valve and an emergency button which is installed on a cab instrument panel. The spare brake device for the car is simple in structure, easy to manufacture and install, good in integral rigidness and large in friction force.

Description

A kind of automotive spare braking device
Technical field
The present invention relates to brake system of car, be specifically related to a kind of automotive spare braking device.
Background technology
In general, brake system of car comprises independently device of service braking device and holding brake device two covers.Wherein service braking device is that chaufeur is handled with pin, so claim again " service brake "; Holding brake device is that chaufeur is hand-operated, so claim again " parking brake ".But in real life, whole world every day is all in the traffic accident that car crash occurs.Mainly, poor stop untimely with overspeed of vehicle, overload, road is wet and slippery or the 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 spare braking device both at home and abroad, proposed many schemes, but up to the present, not yet find actual applying.
Summary of the invention
The objective of the invention is to overcome the deficiency of above-mentioned background technology, a kind of practical automotive spare braking device is provided, under emergency situation, shorten stopping distance, prevent the collision case generation or alleviate the collision extent of injury.
The objective of the invention is to realize with the following methods.A kind of automotive spare braking device, mainly formed by hydraulic ram, swivel arm, pitman shaft, friction shoe folder and friction shoe, the piston rod front end of hydraulic ram is fixed with 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, is similar to the match Sports shoe sole of a plurality of little iron nails, 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 invention 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 large, contains easily the uneven profile on road surface, 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 invention, i.e. fundamental diagram; Accompanying drawing 2 is birds-eye view of the present invention, i.e. main assembly figure; Accompanying drawing 3 is embedded iron nail array friction shoe scheme drawing of the present invention.
The specific embodiment
Below with reference to accompanying drawing enforcement of the present invention is described further.
Automotive spare braking device of the present invention, 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 are fixed with 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 drying or wet-skid 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 immediately the critical button on the facia board under the emergency situation of serious collision, starts automotive spare braking device.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 occurs.
When automotive spare braking device 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.
