Embodiment Construction

[0007] The implementation of the present invention will be further described below with reference to the accompanying drawings.

[0008] The automobile spare braking device of the present invention is mainly composed of a hydraulic cylinder 1, a rotating arm 4, a connecting rod shaft 7, a friction block clamp 8 and a friction block 9. A cylinder pin 3 is fixed at the front end of the piston rod 2 of the hydraulic cylinder 1. , the cylindrical pin 3 can perform relative movement in the straight groove on the left side of the rotating arm 4, the middle part of the rotating arm 4 is rotatably matched with the vehicle axle 6 through the bushing or the sliding bearing 5, and the right end of the rotating arm 4 is clamped by the connecting rod shaft 7 and the friction block 8 is connected to the friction block 9. The connecting rod shaft 7 also connects the braking devices on both sides of the axle as a whole to enhance the overall rigidity. The friction block 9 is an air bag rubbe...

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

technical field [0001] The invention relates to an automobile braking system, in particular to an automobile backup braking device. Background technique [0002] Generally speaking, the automobile brake system includes two independent devices, the service brake device and the parking brake device. Among them, the service brake device is operated by the driver's feet, so it is also called "foot brake"; the parking brake device is operated by the driver's hand, so it is also called "hand brake". But in real life, traffic accidents involving car crashes and fatalities occur every day all over the world. This is mainly related to the untimely braking, excessive braking distance or failure of the braking device caused by overspeeding, overloading, slippery or icy roads, etc. Therefore, many people at home and abroad are carrying out research on emergency braking devices or backup braking devices, and have proposed many schemes, but so far, no practical application has been foun...
