Description
Technical field
The present invention relates to automobile technical fields, and in particular to a kind of central axle sedan-chair fortune vehicle coupler auxiliary connecting device.
Background technique
Currently, the main transport vehicle of central axle sedan-chair fortune front of the host with subsequent trailer is connected by dedicated coupler, in height
When running at high speed on fast highway, the case where encountering turning or in the case where bringing to a halt, it may appear that the whipping phenomenon of subsequent trailer,
Coupler will lead to coupler fracture by shearing force maximum so repeatedly at this time, so that subsequent trailer is detached from；If vehicle
Travel too fast, when trailer whipping of rear of vehicle will cause trailer rollover also to drive the main transport vehicle of front also to follow side
It turns over.
Summary of the invention
For the deficiency in the presence of the prior art, the present invention provides a kind of couplings between main transport vehicle and trailer
Device carry out auxiliary protection central axle sedan-chair transport vehicle coupler auxiliary connecting device, it is possible to prevente effectively from when coupler is broken its
The trailer at rear occurs to be detached from or turn on one's side.
To achieve the above object, present invention employs the following technical solutions:
Central axle sedan-chair transports vehicle coupler auxiliary connecting device, including the coupler for connecting main transport vehicle and trailer, also
Including the auxiliary connecting device below the coupler that is arranged between main transport vehicle and trailer, auxiliary connecting device includes two steel wires
Bottom of the main transport vehicle towards the side of trailer is arranged in rope fore-stock, wirerope after-poppet and wirerope, two wirerope fore-stocks
It portion and is axisymmetricly distributed centered on coupler, trailer is arranged in towards in the bottom of main transport vehicle side in wirerope after-poppet
Centre, wirerope one end are fixed on the one of wirerope fore-stock in main transport vehicle bottom, and the other end passes through the steel wire of trailer bottom
Rope after-poppet is simultaneously fixed on another wirerope fore-stock of main transport vehicle bottom.
Compared with the prior art, the present invention is auxiliary by being arranged below the coupler between trailer in main transport vehicle and thereafter
Attachment device is helped, auxiliary connecting device, which can play main transport vehicle and trailer, when coupler is broken temporarily connects
Effect prevents trailer and main transport vehicle to be detached from, and when vehicle driving is too fast, due to the wirerope both ends in auxiliary connecting device point
It is not fixed on main transport vehicle rear end, the center of trailer front end is passed through in the middle part of wirerope, and wirerope has certain hardness, therefore
Wirerope is arranged in below coupler in circular ring shape, therefore when trailer whipping, the wirerope of circular ring shape can also be played trailer
The effect of dragging prevents occurring rollover event when trailer whipping, therefore the present invention greatly reduces central axle sedan-chair fortune vehicle coupler
It is broken the accident ratio caused, improves the security performance of driving.
