Abstract
The utility model relates to a braking bumper which belongs to a safety protection device for the locomotive. The braking bumper is a new mechanical part which can reduce the loss of the right side collision of the vehicle. A braking system comprises a gear rack, a gear wheel a transmission shaft, a rope wheel, a wire rope, a gear rack limit and a gear rack screw cap. A shock mitigation system comprises a movable bumper, the tailstock of the movable bumper, a spring and a supporting limit steel plate. By using the impact force of the vehicle collision, the gear rack is driven, the gear wheel and the rope wheel can rotate, and the wire rope can be rolled up; so a pedal brake can be pulled to a braking position, and the locomotive can stop instantly. Because the damping effect of the spring, the loss of the vehicle collision is reduced. By using the impact force, a high-pressure air tank valve is opened, and the air cushion of the chair back can be filled with the air; thereby, the safety of a driver and passengers can be protected.
Description
The safety guard that belongs to locomotive is a kind of utility model device that reduces the positive loss of colliding.
Locomotive in travelling takes place to make lives and properties cause massive losses, various countries' car manufacturer from hitting or knock against each other.The commercial city is at concentrated research crash-avoidance; or the measure of reducing the loss after colliding; produced a kind of automobile that steam cushion is installed recently abroad on control wheel; the strenuous vibration that the takes place during collision chemical substance in the storage tank in the car of having ignited; moment produces the high pressure gas; be full of steam cushion, the safety of protection chaufeur.
Propose in prospect nineteen ninety one literary composition that U.S. AutOmOtiVe Engineering magazine OCtOber1989 publishes to press spring, to alleviate the loss of colliding at the front bumper rear portion of automobile.
The purpose of this utility model provides the active bumpers that vehicle moment is stopped, and actv. alleviates the loss of colliding.And can in time open the valve of high pressure gas holder, make on the control wheel with the front-seat chair back on steam cushion, gas-filled protective chaufeur and passenger safety.
The purpose of this utility model is to realize like this
Movable front bumper has two tailstocks to be set in the channel-section steel about vehicle frame, and shock mount behind the thick stick, thick stick rear wall have two tooth bars, connect the gear of back, and the valve of the brake of steel rope connecting pin and high gas tank on the rope sheave wheel is arranged on gear coaxial.
After the collision, bumper/spoiler retreats.Length of spring compressed; tooth bar straight line backward moves; arm revolving gear, rope sheave tightens up steel cable; the pulling foot brake stopped to braking position locomotive moment; the cushioning effect that adds upper spring, actv. alleviate the loss of colliding, and tighten up steel cable and have also opened the valve of high pressure gas holder the air cushion on control wheel and the preceding chair back is inflated; protection chaufeur and passenger's safety is because braking is to be symmetrically arranged with shock mitigation system.When colliding in the front, rum point is no matter on an active bumpers left side or right, can both move immediately.
The utility model is simple in structure, is a kind of independently parts, produces new car energy usefulness, and used car installs additional also easy.
Compared with prior art, this device has tangible advantage, and strong box is fixed before the existing locomotive, and car accident has taken place.Often thick stick is curved, and car is bad, and chaufeur is as not brake in time, and traffic accident is more serious.As the car of having stopped, or flame-out because of the back of colliding, force of inertia also can damage vehicle.This device utilizes the power of bump, moment brake locomotive, spring has the damping section again, the loss of colliding effectively alleviates, the new car of U.S.'s development is compared few bump brake system by shock mount with this device behind active bumpers, security personnel's performance is not as good as this device.
Utilize impact, open the high pressure gas holder valve, gas is full of the air cushion on the control wheel, compares with external homologous ray and has saved the chemical substance in the jar, and the domestic automobile that has has gas supply system to utilize.
The concrete structure of utility model is provided by following embodiment and accompanying drawing thereof, and accompanying drawing 1 is disintegration figure of the present invention, describes concrete part of the present utility model in detail.
It has active bumpers (1) and tailstock (4) thereof; Spring (3), (11) three kinds of parts of support limit steel plate are formed shock mitigation system.Brake system has 2 tooth bars (2); Be stranded the rear wall that fixes on active bumpers with tooth bar nut (13).A pair of gear (6) is arranged on the transmission shaft (7), on a pair of rope sheave (8) wheel steel rope (9) is arranged, the foot brake of ining succession (10), the direction of tooth bar spacing (12) control tooth bar action.
The thick stick rear wall has tooth bar nut (13) stationary rack (2).
Tooth bar (2) is connected with gear (6), on the same transmission shaft (7) of gear (6) rope sheave (8) is arranged, and steel rope (9) is arranged on the wheel.Tooth bar (2) top is close in the in succession position of valve (figure does not draw) tooth bar spacing (12) of foot brake (10) and high pressure vapour jar of steel rope.
Dotted line in the accompanying drawing 2 is a dynamic position of the present utility model, and various parts are pressed the motion of arrow direction.After the collision, active bumpers retreats, spring (3) compression.Tooth bar (2) moves arm revolving gear (6) rope sheave (8) to the previous crops straight line, tightens up steel rope (9) foot brake (10) is moved to braking position, and open high pressure vapour tank valve.
Accompanying drawing 1: the braking safety thick stick disintegrates and schemes.
2, braking safety thick stick working diagram side-looking.
3, braking safety thick stick working diagram fourth is looked.
4, active bumpers top; Back view.
5, gear, tooth bar just, lateral plan.
6, rope sheave just, lateral plan.
7, the support limit steel plate just, lateral plan.
Claims (5)
