Description
Technical field
The invention belongs to technical field of vehicle safety, refer to a kind of vehicle impact testing equipment technical field, particularly relate to one
Plant test vehicle haulage gear and collision system.
Background technology
Complete automobile collision experiment is the Key experiments for detecting vehicle safety energy, and the complete automobile collision experiment now used is such as
Schematic diagram shown in Fig. 1, includes test vehicle, trailer wagon and braking dolly, traction column 2 is set on trailer wagon,
Traction guide groove 1 is set on test vehicle；Connected between trailer wagon and braking dolly by steel wire rope 3；When being tested,
Clamping it will be connected between traction guide groove and traction column.Run from trailer wagon motoring ring test vehicle to crash direction, in collision
Preceding sometime (moment sets in program), test cart is braked dolly braking, and stops, and test vehicle reaches
After the speed needed to experiment, moved on because of inertia, until off-test.
The connection of the trailer wagon and test vehicle of existing technology is realized by drawing column and traction guide groove, wherein leading
Guiding groove is fixed on the suspension of vehicle, there is following deficiency in technical scheme：
1) install inconvenient：Because traction guide groove is the channel-section steel of opening, channel-section steel will be passed through the company of welding during experiment every time
It is connected on the chassis suspension of test vehicle, operates very inconvenient；Chassis also on-plane surface simultaneously, what traction guide groove was installed is vertical
Property and stability requirement need to take much time and can be only achieved test requirements document.
2) cost is higher：Due to channel-section steel be by being welded on chassis, therefore channel-section steel use be it is disposable, from
And improve the cost of experiment.
3) the accuracy presence of experiment must deviation：Due to channel-section steel be welded to chassis together with formed an entirety,
Test vehicle is simply due to external force to draw, and the result of the four-wheel aligner of each car there may be difference, can so lead
Cause to exist in final collision precision must deviation, and cause the inaccurate of result.
To be rigidly connected between trailer wagon and traction column, in process of the test, between traction column and traction guide groove
For rigid connection, process of the test is caused to there is certain deficiency：
1) there is the risk that traction guide groove comes off：Due to being Hard link, test vehicle between traction column and traction guide groove
Trailed power is transmitted by drawing guide groove completely, if being likely to occur traction in traction guide groove failure welding, process of the test
Guide groove and vehicle body separation, so as to cause test failure.
2) cause velocity error larger：Because test vehicle needs to separate with trailer wagon before collision, it is ensured that experiment
Vehicle is hit in the absence of external forces, it is desirable to be more late better, such energy that test vehicle is separated with trailer wagon
The speed of enough guarantee test vehicles meets the requirement of experiment, but trailer wagon is reverse by steel wire rope after braking dolly braking
Braking, steel wire rope has mobile elasticity in itself, if the disengaging time of setting is shorter, there is trailer wagon and test vehicle
What is separated is not thorough, so as to influence final test speed.
3) secondary collision is easily caused：In central collision process of the test, after impact test, test vehicle has very big inclined
Turn, because traction column remains that original vertical state is constant, the experiment of collision rift is may result in process of the test
Vehicle touches traction column, so as to occur the possibility of secondary collision with collision obstacle.

The contiguous block 06 is mounted with the traction component.
The traction component includes traction hook 07, traction column 08, base 09 and connecting pin 10；
Described traction one end of column 08 is fixedly connected with the traction hook 07, and the other end is fixed with the base 09 to be connected
Connect.
The base 09 is non-equilateral polygon, in the present embodiment, and base is non-equilateral octagon.On the base
It is provided with centre bore 091；The connecting pin 10 passes through the centre bore 091；The traction component by axle of the connecting pin with
The towing vehicle 02 rotates connection.
The base 09 it is relative with the bottom surface of the towing vehicle while for first while 092, it is adjacent with first side 092
Two while for second while 093 and the 3rd side 094.
Described first while 092 length be less than described second while 093 length, again smaller than the length on the 3rd side 094.
The said structure of base allows base to be rotated around connecting pin, but second while or bottom surface when the 3rd with towing vehicle do
Relate to, it is to avoid traction component transition is rotated and reversely hindered and test vehicle connection component departs from.
The extended line on first side, with described second at the described 3rd between angle be 37 ° ± 0.5 °.Lead
Draw vehicle after being braked by abrupt deceleration vehicle 03 below, even connecting rod 12 is replaced and flexible, traction with steel wire rope
Vehicle continues to move along a segment distance because of inertia, but traction column can because the pulling force of abrupt deceleration vehicle steel wire rope and to
Arrow F directions in Fig. 5 are toppled over, so that while separation is realized, while after traction column is toppled over, traction column, which stretches out, to be led
The part for drawing vehicle is less than 10cm ± 1cm, the height of reduction traction column, it is to avoid the secondary collision of vehicle.
It is described traction hook 07 include hanger bulk 071, and with being folded upward at that the hanger bulk 071 is structure as a whole
Portion 072.
The lower surface of the hanger bulk 071 is provided with neck 073, peace is provided with the bottom surface of the neck 073
Hole 074 is filled, the upper end of the traction column 08 is caught in the neck 073；Traction hook directly uses nut with traction column
Connection, traction hook is fixed on the top of traction column.
