Description
Technical field
This utility model belongs to automobile technical field, relates to a kind of leading for impact test
Draw dolly.
Background technology
In complete automobile collision is tested, it is usually and uses traction electric machine moving as trailer system
Power, utilizes the principle that band transmits, by wirerope or iron chains are arranged on trailer wagon,
Under the drive of trailer wagon, deliver power to test vehicle, at test vehicle distances obstacle
During certain distance, wirerope or iron chains is made to depart from trailer wagon by relieving mechanism, it is ensured that to survey
Test run is in a free state with the speed impacts obstacle of regulation.Test regulation crashes the speed hit
There are very strict requirements degree, the position of collision, and the control accuracy of usual car speed needs
Will be at 0.2km/h, final impact velocity error requirements is in the range of 1km/h, and position of collision
Error requirements is within 20mm.For a length at the test traction runway of more than 100m
Speech, either impact velocity or position of collision, it is desirable to be all the highest.
Authorization Notice No. is that the Chinese utility model patent of CN 202177515U discloses one
The trailer wagon being automatically releasable of impact test, including vehicle body, leading of being arranged on vehicle body
To device, be arranged on vehicle body top for pull test vehicle traction link up with and be arranged on car
Relieving mechanism in body, relieving mechanism includes being arranged on the taper on fore-and-aft direction in vehicle body and leads to
Hole, the sleeve being slidably arranged in conical through-hole and be slidably arranged on conical through-hole
At least three claws before inner sleeve, at least three claws are that circumference is uniformly distributed in taper and leads to
In hole.
Above-mentioned trailer wagon by being positioned at the claw front end impact obstacle of trailer wagon front end,
Claw is pushed away by interior, thus discharges the wirerope between claw, reaches to be automatically releasable the mesh of wirerope
, its weak point is: claw is more firm to the clamping of wirerope, therefore trailer wagon with
Need between obstacle that there is bigger impact force could inwardly be promoted by claw, if impact force
If too small, it is possible that claw can not discharge the situation of wirerope in time, cause drawing little
Disengaging between car and wirerope is inconvenient.
Summary of the invention
