Description
Technical field
The invention belongs to vehicle braking control system technical field, especially a kind of safety is good, success rate is high, at low cost
Vehicle automatic emergency brake experimental rig.
Background technique
Due to driver distraction or erroneous judgement, vehicle-to-vehicle knock into the back is that most frequent one of accident occurs on road.City driving
Under operating condition, typical rear-end collision is generally divided into two kinds: a kind of situation is that rear-end collision occurs at relatively low speeds.It is hit
The vehicle hit has stopped, but due to higher accelerations, this hit causes the upper part of the body and head to by the driver of collision
Whipping, generate the dangerous of injury.Although injuring, severity is usually lower, and this accident is very frequent, Zhan Suoyou
It is more than a quarter of traffic accident.Another situation is that rear-end collision occurs with medium or higher speed on open road
Situation.Driver may divert one's attention to cause driver will so that it cannot identify that front vehicles have been slowed down or stopped
Vehicle rationally slows down or stops.In this case injury caused by is general relatively high.
In order to reduce or avoid above-mentioned car accident, a kind of Chinese utility model patent application " automatic emergency brake to the greatest extent
Experimental rig " (application number: 201620608284.7, publication date: 2016-11-16) disclose a kind of automatic emergency brake test
Device, including pre-traction device, attachment device, balloon underbody seat and balloon vehicle, wherein attachment device is connected by multiple connection frames
It constitutes, the pre-traction device, attachment device and balloon underbody seat are sequentially connected end to end by bolt；The pre-traction device
Front is equipped with traction stay hook, and pre-traction device is connect by drawing stay hook with towing vehicle tail portion；Balloon vehicle passes through drawstring
It is fixed in balloon underbody seat, towing vehicle drives balloon vehicle traveling by pre-traction device, attachment device and balloon underbody seat.
Above-mentioned experimental rig has the following problems:
1, since stiffness of support is larger, entire experimental rig can be regarded as a rigid body, and which results in once load AEB
When the vehicle and experimental rig of system form shock, the vehicle of experimental rig and loading AEB system may be caused to a certain degree
Injury.
2, not readily portable, transportation cost is high since bracket volume is big.
3, it is made due to bracket of a large amount of Metal Material Weldings, the cost of raw material is high, and processing cost is high.
4, since " commerial vehicle automatic emergency brake system performance requirement and survey can only be unable to satisfy along straight-line travelling
Try regulation " in about bend transverse direction target identification test requirement.
Summary of the invention
The purpose of the present invention is to provide a kind of vehicle automatic emergency brake experimental rig, safety is good, success rate is high, at
This is low.
The technical solution for realizing the aim of the invention is as follows:
A kind of vehicle automatic emergency brake experimental rig, including towing vehicle 1, pre-traction device 2,4 and of balloon kickstand
The vehicle-mounted air pump that balloon vehicle ontology 5 further includes loading line 7 and is arranged on towing vehicle 1；Described 7 one end of loading line with
2 airtight connection of traction device, the other end and 4 airtight connection of balloon kickstand, the towing vehicle 1 and pre-traction device 2 are fixed
Connection, and the vehicle-mounted air pump output end of towing vehicle 1 is communicated with loading line 7.
Compared with prior art, the present invention its remarkable advantage are as follows:
1, safety is good: the present invention is filled with the gas piping of 5-8bar high pressure gas using three to replace existing test to fill
Rigid support in setting, and pressure sensor and pressure-regulating valve are mounted on pipeline.The present invention will be in existing experimental rig
One-way wheel be substituted for universal wheel.Due to inflation tracheae when being hit internal gas can compress, shake, consumption is hit
The energy hit；Simultaneously when hypertonia, relief valve is opened, the partial pressure in discharge conduit；And it is universal due to using
Wheel, when being hit, whole device can swing to consume energy.
2, at low cost: gas piping is rolled after can emptying internal gas when not in use, the support frame volume of pipeline
Small, light-weight, experimental rig is easy to carry and transport；The gas piping used for two-sided Ding Qingguan, light water/tracheae usually by
Inside and outside two layers of composition, internal one layer of rubber play sealing function, and the materials such as external nylon weave to prevent from wearing；Two-sided fourth is fine
All be made of nitrile rubber for inside and outside two layers of pipe, surface abrasion resistance damage, shock resistance, in terms of better than light water/air pipe.
Gas piping is fixed on the bracket equipped with idler wheel by band, and without welding, material and processing cost are compared with metal truss structure
It substantially reduces.
3, success rate is high: this experimental rig can be by adjusting the length of two sides gas piping, pipeline inner pressure and rolling
The angle of wheel changes the moving radius of experimental rig, makes it in bend test testing engineering, also can be along test lane row
It sails.
The present invention is described in further detail with reference to the accompanying drawings and detailed description.
