Abstract
A tractor extraction and braking device has a dragging ball installed on the traction vehicle, one end of the extraction axis connecting with the drag ball and locked by extraction locker, the other end fastened inside the extraction seat fastened on the trailer, with the reverse spanner in L shape, positioning point at the front of the extraction seat, bottom steadily matched with the extraction axis, prionodont locating slot at the top of the extraction seat locking with the manual locating plate on the brake handle connected with one end of the trailer, with the end of the brake handle connecting with the regulating device that connects with the brake iron wire. It gets rid of steering device using ball connection, simplifies the drive mechanism, reduces costs, being more flexible and reasonable in overall design, free from any tube connection on the brake system, being simple in structure, convenient in operation, and enduring in use.
Description
Technical field
The invention belongs to a kind of traction and brake equipment, particularly a kind of trailer traction, brake equipment.
Background technology
The present invention in the past, trailer adopts four-wheel to travel more, and draw gear all has steering hardware, and design is complicated, the manufacturing cost height, and brake system is by the power of tractor truck glancing impact output, as oil pressure or air pressure, makes brake system work, the intermediate demand pipeline connects, in case the bonded assembly pipeline goes wrong, brake system will get out of hand, and therefore the reliability of safety is relatively poor.
Summary of the invention
The objective of the invention is to overcome above-mentioned defective, a kind of trailer traction, brake equipment are provided.
Technical scheme of the present invention is: a kind of trailer traction, brake equipment, drag are installed on the tractor truck, and an end of axis of traction connects drag, and by the locking of traction lock, the other end is set in the traction seat that is fixed on the trailer body; The reversing wrench is the L type, and fulcrum is fixed on the traction seat front end, and surely close mutually with axis of traction the bottom; The traction seat upper end is provided with the sawtooth pattern positioning groove, and with hand braking locating plate of installing on the trailer body one end bonded assembly brake-applying handle and the locking of sawtooth pattern positioning groove, the end of brake-applying handle connects control apparatus, and control apparatus is connected with brake wire.
Clamped pressure spring between said traction seat and axis of traction.
The present invention has following advantage: 1, sphere connects, remove steering hardware, four-wheel becomes two-wheeled and travels, and simplifies transmission device, cost-cutting, turn to more flexibly, make car load design more reasonable, 2, brake equipment need not any pipeline and connect, only realize braking by the trailer inertia that travels, simple in structure, easy to operate, sturdy and durable.
Description of drawings
Accompanying drawing 1 is a structural profile scheme drawing of the present invention.
The specific embodiment
As shown in the figure: a kind of trailer traction, brake equipment, drag 1 are installed on the tractor truck 6, and an end of axis of traction 2 connects drag 1, and by 12 lockings of traction lock, guarantee the safety in the traveling process, and the other end is set in the traction seat 3 that is fixed on the trailer body 7; Reversing wrench 4 is the L type, and fulcrum is fixed on traction seat 3 front ends, and surely close mutually with axis of traction 2 bottom; Traction seat 3 is provided with sawtooth pattern positioning groove 8, with hand braking locating plate of installing on the trailer body 7 one end bonded assembly brake-applying handles 59 and 8 lockings of sawtooth pattern positioning groove, the end of brake-applying handle 5 connects control apparatus 10, control apparatus 10 is connected with brake wire 11, and 2 of traction seat 3 and axis of traction have clamped pressure spring 13.
