As shown in fig. 1-2, the utility model relates to a brake system for a trailer, which comprises a traction shaft 1 and a trailer hopper 2, wherein a brake drum 9 is arranged at the wheel position of the trailer hopper 2, a mounting bracket 3 is also fixedly arranged on the trailer hopper 2, the mounting bracket 3 comprises a frame body in an isosceles trapezoid shape and a cross beam crossing the frame body, and the top of the frame body and the cross beam are both provided with sliding holes in a matching manner; the cross beam of the mounting bracket 3 is provided with two groups of fixed pulleys 5, the two groups of fixed pulleys 5 are symmetrically arranged along the axis of the frame body, a movable pulley 6 is arranged between the two groups of fixed pulleys 5, the movable pulley 6 is arranged on the axis of the frame body, the mounting bracket is also provided with a connecting rope 4, two ends of the connecting rope 4 are respectively arranged on brake drums 9 at two sides of the trailer hopper 2, the connecting rope 4 sequentially passes through the fixed pulley 5 and the movable pulley 6 at one side and the fixed pulley 5 at the other side, and the connecting rope 4 is a steel wire rope; in addition, a connecting column 7 is also hinged on the movable pulley 6, and the movable pulley 6 can freely rotate along the axis of the movable pulley; the connecting column 7 is connected with the traction shaft 1, and the connecting column 7 and the traction shaft 1 respectively penetrate through the sliding hole of the beam and the sliding hole of the frame body and can slide in the sliding holes. The utility model discloses well brake drum 9 and the mode that sets up between being connected rope 4 can adopt the mode in the utility model patent that application number is CN01237797.X to set up.

In order to return the cable to its original position after braking and avoid fatigue from affecting the service life, in one embodiment, the connection column 7 and the traction shaft 1 are connected by an elastic member 8, and the elastic member 8 can be configured as a spring.

After the brake system is arranged, if the vehicle backs up backwards, the traction shaft 1 drives the connecting column 7 to force the steel wire rope to act on the brake drum 9, so that the vehicle cannot back up. In order to avoid this, in another embodiment, the present invention further comprises a pin 10, the pin 10 is embedded on the mounting bracket 3, and the pin 10 is detachably connected to the traction shaft 1. When the pin 10 is detached from the traction shaft 1, the brake system functions and can play a good braking role; when the pin 10 is fixedly connected with the traction shaft 1, the brake system does not play a role, and at the moment, the traction shaft 1 acts on the mounting bracket 3 through the pin 10, so that the backing-up can be smoothly realized.

For the assembly of the pin 10, a first mounting hole can be formed in the mounting bracket 3, a second mounting hole is formed in the traction shaft 1, in order to avoid the loss of the pin 10, the pin 10 is in threaded connection with the first mounting hole, the change of the relative position of the pin 10 on the mounting bracket 3 can be realized by rotating the pin 10, in addition, the pin 10 and one end of the pin 10 are clamped into the second mounting hole by rotating the pin 10, so that the relative fixation of the pin 10 and the traction shaft 1 can be realized, and the reversing can be realized. In addition, in order to further ensure the stability of the connection between the pin 10 and the traction shaft 1, the pin 10 is also screwed into the second mounting hole.

In order to avoid the driver to get off to carry out the dismouting of pin 10 and traction shaft 1 and be connected, realize the automatic assembly between pin 10 and the traction shaft 1, in another embodiment, the utility model discloses still include with pin 10 fixes the solenoid valve on traction shaft 1. When the electromagnetic valve is opened, the pin 10 is clamped on the traction shaft 1; when the solenoid valve is closed, the pin 10 is disengaged from the traction shaft 1.

In order to achieve a more stable mounting between the pin 10 and the traction shaft 1, in a further embodiment, said solenoid valve comprises a coil 11 arranged on one side of the mounting bracket 3, the pin 10 being arranged on the opposite side of the coil 11; the traction shaft 1 is provided with a through hole 101 matched with the pin 10, and the coil 11 obtains magnetism after being electrified and attracts the pin 10 to enter the through hole 101.

In order to facilitate a more rapid and stable mounting of the pin 10 on the traction shaft 1, in a further embodiment, a plurality of through holes 101 are provided side by side.

And after the vehicle is backed, if the pin 10 is still assembled on the traction shaft 1, the brake system can not work, in order to realize the use of the brake system more automatically, in another embodiment, one end of the pin 10, which is positioned at the outer side of the mounting bracket 3, is also provided with a handle, the handle can limit the displacement distance of the pin 10, and the handle of the pin 10 is connected with the mounting bracket 3 through a spring.

In the specific working process, when the vehicle is emergently braked, the trailer hopper 2 and the mounting bracket 3 can continuously move forwards due to the inertia effect, at the moment, the traction shaft 1 forces the movable pulley 6 to move backwards through the elastic part 8 and the connecting column 7, and the movable pulley 6 presses the steel wire rope and acts on the brake drums 9 at the two sides of the trailer hopper 2, so that the stable braking effect is achieved; in addition, if the goods in the trailer hopper 2 are heavier, the inertia of the goods is larger, the acting force on the steel wire rope is larger, and the whole braking effect is very effective. In addition, when the vehicle needs to be backed, the coil 11 is electrified, and the pin 10 is driven by magnetic force to move towards the direction of the traction shaft 1 and is clamped into the through hole 101, so that the vehicle can be backed smoothly by directly acting on the mounting bracket 3 through the traction shaft 1 and the pin 10 in the process of backing. After the backing car is finished, the coil 11 is powered off, the magnetic force of the coil 11 disappears, and due to the restoring force of the spring connected with the pin 10, the pin 10 is separated from the traction shaft 1, so that the brake system can be ensured to be used smoothly.

The present invention is not limited to the above-mentioned optional embodiments, and any other products in various forms can be obtained by anyone under the teaching of the present invention, and any changes in the shape or structure thereof, all the technical solutions falling within the scope of the present invention, are within the protection scope of the present invention.
