Abstract

The utility model discloses an auxiliary brake device for automobiles, which is composed of a fixing frame and a motor, wherein an output axle of the motor is engaged with a telescopic strip which can continuously extend and shrink; the lower end of the telescopic strip is fixed with a friction strip; the telescopic strip is movably fixed on the fixing frame; the fixing frame and the motor are fixed on an automobile body; the surface of the friction strip is provided with concave-convex patterns, and the friction strip is a hollow inflated strip. The utility model has the characteristics of simple structure, high safety and good braking effect.

Description

A kind of auxiliary automobile braking device

One, technical field

The utility model belongs to automobile technical field, especially relates to a kind of auxiliary automobile braking device.

Two, background technology

Present development along with society, automobile is as a kind of vehicle, and quantity is more and more, and existing automobile generally only has a cover brake system, adopt the brake of oil pressure or air pressure more, this just exists potential safety hazard, oil circuit is taking place, gas circuit is stopped up or leaking out of reach brake requirement, certainly will cause brake failure or brake weight to weaken, braking distance elongates, and meets accident easily, causes property, personal casualty.

Three, summary of the invention

The purpose of this utility model is to improve the deficiency of prior art and a kind of auxiliary automobile braking device of simple in structure, safe and reliable, applied widely, good braking effect is provided.

The purpose of this utility model is to realize like this, a kind of auxiliary automobile braking device, form by fixed mount and motor, but be characterized in the expansion strip engagement of output shaft with the continuous and adjustable of motor, the lower end of expansion strip is fixed with fricting strip, the expansion strip activity is fixed on the fixed mount, and fixed mount, motor are fixed on the car body.

Realize the purpose of this utility model for further, but can be that the output shaft of motor and the expansion strip engagement of continuous and adjustable are the teeth engagements of the output shaft gear and the expansion strip upper surface of motor.

In order further to realize the purpose of this utility model, can be that the surface of fricting strip is provided with ridge design.

In order further to realize the purpose of this utility model, can also be that fricting strip is hollow inflation bar.

Compared with the prior art the utility model has following distinguishing feature and good effect: but the utility model adopts the expansion strip engagement of output shaft with the continuous and adjustable of motor; the lower end of expansion strip is fixed with fricting strip; the expansion strip activity is fixed on the fixed mount; fixed mount; motor is fixed on the car body; stretch out downwards continuously by the driven by motor expansion strip; fricting strip is sent into the wheel below of rotation; cause friction force to strengthen; reach the purpose of abrupt deceleration vehicle, the surface of fricting strip is provided with ridge design, to increase friction force; improve braking effect; fricting strip is hollow inflation bar, guarantees the vehicle buffer-braking, protection tire and vehicle safety.

Four, description of drawings

Below in conjunction with drawings and Examples the utility model is described in further detail.

Fig. 1 is a kind of structural representation of the present utility model.

Fig. 2 is a kind of structural representation of the utility model fricting strip.

Fig. 3 is the another kind of structural representation of the utility model fricting strip.

Five, specific embodiments

Embodiment 1, a kind of auxiliary automobile braking device, with reference to Fig. 1, be that fixed mount 1, motor 2 are fixed on the car body, but the output shaft of

motor

2 and 3 engagements of the expansion strip of continuous and adjustable drive expansion strip 3 continuous and adjustables, and the lower end of expansion strip 3 is fixed with fricting strip 4, expansion strip 3 activities are fixed on the fixed mount 1, and this constitutes a kind of structure of the present utility model.

Embodiment 2, a kind of auxiliary automobile braking device, with reference to Fig. 1, Fig. 2, be on the basis of embodiment 1, but the output shaft of motor 2 is to adopt the engagement of the teeth of the output shaft gear of motor 2 and expansion strip 3 upper surfaces with 3 engagements of the expansion strip of continuous and adjustable, and the teeth engagement by motor 2 output shaft gears and expansion strip 3 surperficial diverse locations reaches the purpose that makes expansion strip 3 continuous and adjustables, the surface of fricting strip 4 is provided with ridge design, and other and embodiment 1 are identical.

Embodiment 3, and a kind of auxiliary automobile braking device with reference to Fig. 1, Fig. 3, is on the basis of embodiment 2, and fricting strip 4 is hollow inflation bar, and other and embodiment 2 are identical.

When using the utility model, this device is fixed on the place ahead of wheel, when the needs emergency braking, can connect motor 2 power supplys, motor 2 rotates, and drives expansion strip 3 and moves downward continuously, and fricting strip 4 is sent into the wheel below, wheel just is braked, reach the brake purpose, during withdrawal, oppositely connect motor 2, motor 2 counter-rotatings drive expansion strip 3 withdrawals continuously and get final product.
