Abstract

The utility model discloses an automotive emergency brake which belongs to the brake mechanism of the auxiliary device of automobiles. The outline forms a J shape. The opening end forms a flare shape, and the left end is a cavity whose shape likes the Chinese character 'tu'. The right end is an air chamber [7], a pipe wall is provided with the brake pipe [6]which can go in or out the air port. The back end of the closed air chamber of the right end of the brake pipe is a piston, and the front end is a right angle type guide rod [5] with a split port. The right angle head of the guide rod in the cavity at the left end is connected with a chain [4]. The lower part of the chain is provided with a reverse tooth-shaped antislip hoof [3], the upper part is provided with a brake plate of a roller [2] which can rotate along the clockwise direction. The upper side of the left end of J-shaped tube of the brake pipe is provided with a cylinder-shaped spacing mechanism [10]. The utility model has the advantages of simple and feasible structure, convenient use, and good effect of emergency brake.

Description

Automotive emergency brake

The utility model belongs to the brake machinery of automobile auxiliary device.

Automobile brake is the emergency braking during high speed particularly, most moments with driving engine and wheel stop operating and realize, but because the inertia of the speed of a motor vehicle is big to the wearing and tearing of wheel, stopping distance is long, should not deal with burst accident, also can make the unexpected stall of machine cause machine members.

The purpose of this utility model provides a kind of easy to operate, not the emergency braking apparatus of abrasive parts using and wheel.

A kind of emergency brake for automobile, it is characterized in that profile is a J-shaped, open end flare left end is soil-shaped cavity ［ 9 ］, right-hand member is air chamber ［ 7 ］, tube wall is brought the brake pipe ［ 6 ］ of air extractor duct into, the brake pipe right-hand member is airtight, it is piston that the rear end is arranged in the air chamber, front end is the guide rod ［ 5 ］ that the square band is split mouth, guide rod right angle head in the left end cavity connects chain ［ 4 ］, chain has pawl shape skidproof hoof ［ 3 ］ below connecting, and the slipper ［ 1 ］ of the roller ［ 2 ］ of clockwise direction rotation is arranged above, and brake pipe J type pipe left end upside is equipped with drum shape stop gear ［ 10 ］ and constitutes.

In this stop gear by the lower end for splitting shape, the upper end is adjustable at the top cover place, middle spring ［ 11 ］ formation for overlapping on plunger pin of plunger ［ 12 ］ and the plunger upper part post.

Air inlet/outlet is connected with the air pump of vehicle during use, switch places and makes things convenient on the position in the operator's compartment, during brake, in original braking mechanism work, make compressed gas enter the control cabin ［ 13 ］ of stop gear and the left end of air chamber simultaneously, plunger pin is risen, splitting of post, leave the mouth of splitting of guide rod, guide rod moves right the drive chain and moves right in cavity under the effect of compressed gas, slipper falls in J type bend, falls the automotive wheel below, wheel rotates on the roller on the slipper, until stall, and the weight of car also drops on the slipper, and slipper and ground-surface friction force are owing to the effect of skidproof hoof strengthens, thereby reach not abrasive parts using, and reduce the purpose of stopping distance.Can in time gas be bled off from control cabin and air chamber after the braking, during brake off, the vehicle backward and by switch to air chamber right side inflation, promote guide rod to left movement, guide rod and chain are entered in the upper and lower chamber of cavity simultaneously, slipper enters in the J-shaped bend.Plunger pin falls under action of the spring, enters guide rod and splits a mouthful interior locking.

The utility model has the advantages that simple in structurely, feasible, easy to use, emergency brake is effective.

Accompanying drawing 1 is the cross-sectional view of emergency brake for automobile, and Fig. 2 is a cavity place section drawing, and Fig. 3 is a slipper structure enlarged diagram, 1-slipper wherein, 2-roller, 3-skidproof hoof, the 4-chain, 5-guide rod, 6-brake pipe, the 7-air chamber, 8-wheel, 9-cavity, the 10-stop gear, the 11-spring, 12-plunger pin, 13-control cabin.

During enforcement making the pawl shape under the arc slipper, punch on two side guard plates, load onto the roller that clockwise direction rotates onboard, slipper rear end axle and chain join, the brake pipe right-hand member is made the branch nodular, the left end opening is sent into the cavity bottom to chain and slipper in fourth shape bend, again guide rod right angle, chain rear end end, guide rod from cavity top, pass from the hole of cavity and air chamber, the piston of screwing on the guide rod connects the brake pipe of air chamber part again, seal up open end, in the sealing end upper hole, insert plunger pin again, fix stop gear, be loaded on the wheel top and get final product.

Claims

A kind of emergency brake for automobile, it is characterized in that profile is a J-shaped, open end flare left end is soil-shaped cavity [9], right-hand member is the brake pipe [6] that air chamber [7] tube wall is brought air extractor duct into, it is piston that the rear end is arranged in the brake pipe right-hand member sealed gas chamber, front end is the guide rod [5] that the square band is split mouth, guide rod right angle head in the left end cavity connects chain [4], chain has pawl shape skidproof hoof [3] below connecting, the slipper [1] that the roller [2] of clockwise direction rotation is arranged above, brake pipe J type pipe left end upside are equipped with drum shape stop gear [10] and constitute.
