Abstract

The invention relates to an emergency spare brake device and belongs to a device for timely parking under a brake failure condition. The device has the main technical characteristics that a front mudguard (special form) hung on a rear wheel of an automobile is instantly put down and is in contact with the ground through a manual control system when the brake is in failure, the front mudguard is pressed by the wheel during a running process, a front inertia force is transferred to a contact point of the mudguard and the ground, and a brake effect is generated by the friction between the mudguard and the ground, so that the running stop of the wheel during the running process is realized. When the device is assembled on various passenger and freight vehicles, the happening of terrible traffic accidents can be avoided, and a reliable safeguard for the safe parking under the brake failure condition is provided.

Description

Spare braking system in the brake failure situation

Technical field: the invention belongs to automobile mechanical and make the class BAS.Be particularly related to passenger vehicle, lorry because long-time descending causes producing a large amount of heat energy between brake drum and abrasive segments, causes the unexpected malfunctioning automobile that makes of brake system independently not stop under steam, and what each parts cisco unity malfunction produced slips down a slope.

Background technology: in recent years, news media often are reported in often has the motor omnibus lorry because running into descending on express highway, meet with brake failure on the ramp, and the event that causes car to be spoken sarcastically dying can be found everywhere.Be an old driver who throughout the year drives in Daxing'an Mountainrange because of the inventor, have an intimate knowledge as to this.

If meet with brake failure on the ramp, passenger and freight car generally carries out 1 and robs the shelves operation, namely fast vehicle is hung into low gear by high speed gear, pins down the speed of a motor vehicle by driving engine.If but any problem appears in the driving engine of car and running part, rob both failures of shelves operation.2 run into emergency situation, and the driver usually can shirk the heavy work and choose the light and select hillside, trees, sand drift, insulation strip, utilize the friction force manufacturing to stop; but substantially belong to the suicide hedging; and in case cause danger, domestic highway is not very perfect, and a lot of areas do not possess condition like this.Although special emergency lane all can be opened up in the side, ramp of 3 most mountain area roads.Though it is the effective way that controls the dangerous circumstances that vehicle is reached the hedging road, but still the difficult thing of personal injury or property damage of avoiding occurs.

Goal of the invention: in order to reduce passenger vehicle, the event that the car that lorry and trailer cause in descending highway section brake failure is spoken sarcastically and died.The present invention arises at the historic moment.

Spare braking system under this invention brake failure state, by manual control system, powerful traction system, the mudwing suspension consists of.the approximately Pneumatic pipe cleaner more than 3 kilograms that manual control system stores air receiver is crossed pneumatic switch and is started wheel cylinder, pull the break-in rocker-arm driving device that the U-shaped lock pin is opened, cause the mudwing suspension to start, the special type mudwing that will be present in the baffle limiting frame falls, front fender apron (special type) moment that is suspended on automobile back wheel is put down kiss the earth, the wheel in running condition is pushed down it, front force of inertia is shifted on the contact point on mudwing and road surface, thereby the friction by mudwing and road surface produces the wheel that braking effect reaches in running and shuts down.Thereby complete whole actions, until emergency.

Advantage of the present invention:

1 installs facility, quick.At passenger vehicle, lorry only needs simple operations can complete installation on trailer.

2 need to not support by third party's energy.

3 is with low cost, will be lower as the consumption of batch productive costs.

4 do not need regular maintenance, and inspection in six months once gets final product.

5 do not need to change this car exterior structure gets final product work.

As visitor, lorry, this equipment is installed, in case of emergency starting outfit will reduce brake stroke, snap catch.To play the lifting safety factor for the Automobile Transportation industry, reduce the speak sarcastically generation of the serious accident of dying of the car that causes because of brake failure.

Note limit chute flap assembly (1) 11 can be replaced with multiple strands of 0.8mm wire rope oil.More dwindle cost when making it light, and easy to adjust.

Annotate (2) and be welded with the spacing preiection device at scale-up version mudwing rear portion, can control the tram of dual wheels and mudwing.

(3) this equipment of notes is arranged on the front fender apron position of left and right trailing wheel, and also optional dress is installed separately a side.The bilateral effect is better.

Claims

1. the standby brake gear under a brake failure situation.Comprising manual control system, powerful traction system, mudwing suspension.Manual control system pulls the break-in rocker-arm driving device that the U-shaped lock pin is opened by pneumatic startup wheel cylinder, causes the mudwing suspension to start, and the special type mudwing that will be present in the baffle limiting frame falls, thereby completes whole actions.

2. the standby brake gear under the brake failure situation described according to claim 1, is characterized in that, described mudwing is dual-purpose apparatus, is generally the use of mudwing.After starting, system namely becomes the critical component in brake system.

3. the standby brake gear under the brake failure situation described according to claim 1, is characterized in that, described manual control system power resources can be pneumatic, electronic, and machinery is controlled.

4. the standby brake gear under the brake failure situation described according to claim 1, is characterized in that, described powerful traction system has two schemes, and one is that flexible character two joints of sleeve pipe material form.Two is the boundling draw gear of the high-quality oil thread rope combination of 0.8-1.6mm.(its advantage is that cost is both economical, and is easy for installation.)
