Abstract
The utility model discloses a trailer-towing vehicle automatic towing pin device, which consists of a towing hook, a towing pin, a locknut, a pressure spring, a cylinder pull rod and a cylinder. A pinhole for connecting the towing pin is arranged on the towing hook. The towing pin is connected with the cylinder pull rod through the locknut. The cylinder pull rod is connected with the cylinder. Thepressure spring is sheathed outside the cylinder pull rod. One end of the pressure spring is connected with the towing pin and the other end of the pressure spring is connected with the cylinder. Theutility model has the advantages that the driver can directly control the towing pin through the rocker switch, the operation can be realized without requiring the driver to leave the cab, the structure is simple and reliable and the fatigue of the driver is greatly relieved.
Description
Technical field
The utility model relates to the towing pin device, the automatic towing pin device of particularly full ailer-towing vehicle.
Background technology
Existing full ailer-towing vehicle drives the purpose that trailer is realized traction by towing pin.At some special dimensions, realize separating with trailer, combination by towing pin by controlling for the ailer-towing vehicle of demanding perfection.Can realize, increase driver fatigue intensity in conjunction with needing chaufeur to go to the towing pin prescription repeatedly with separating process.
Summary of the invention
The purpose of this utility model is to solve the deficiencies in the prior art, provides a kind of full ailer-towing vehicle automatic towing pin device.
The technical solution of the utility model is:
The complete automatic towing pin device of ailer-towing vehicle, it is characterized in that, comprise hauling hook, towing pin, jam nut, holddown spring, air cylinder tie rod, cylinder, the pin-and-hole that connects towing pin is arranged on the hauling hook, towing pin is connected with air cylinder tie rod by jam nut, and air cylinder tie rod is connected with cylinder, and air cylinder tie rod is with holddown spring outward, holddown spring one end links to each other with towing pin, and the other end links to each other with cylinder.
When trailer need separate, chaufeur was by operator's compartment rocker switch control cylinder air feed, and this moment, air cylinder tie rod overcame the pressure drive towing pin of holddown spring, and hauling hook and towing pin are broken away from, and realized that trailer separates.Otherwise, directly towing pin is compressed by holddown spring.
The automatic towing pin device of the utility model is compared with old-fashioned structure, is that chaufeur can pass through rocker switch direct control towing pin, need not leave operator's compartment and just can realize operation, and it is simple in structure, reliable, alleviates driver fatigue intensity greatly.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Wherein, 1, hauling hook 2, towing pin 3, jam nut 4, holddown spring 5, air cylinder tie rod 6, cylinder 7, gas port (connecing electromagnetic valve)
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing and the specific embodiment.
In accompanying drawing 1, the complete automatic towing pin device of ailer-towing vehicle comprises hauling hook 1, towing pin 2, jam nut 3, holddown spring 4, air cylinder tie rod 5, cylinder 6.On the towing pin 2 tapped bore is arranged, is furnished with screw thread on the air cylinder tie rod 5, towing pin 2 is connected with air cylinder tie rod 5 by jam nut 3, air cylinder tie rod 5 is connected with cylinder 6, the air cylinder tie rod 5 outer holddown springs 4 that are with, holddown spring one end links to each other with towing pin 2, and the other end links to each other with cylinder 6, and gas is by 7 turnover of gas port.When trailer need separate, chaufeur was by operator's compartment rocker switch control cylinder 6 air feed, and this moment, air cylinder tie rod 5 overcame holddown spring 4 drive towing pins 2, and hauling hook 1 and towing pin 2 are broken away from, and realized that trailer separates.Otherwise, directly towing pin is compressed by holddown spring 4.
