Abstract
The utility model discloses an automatic trailer parking device, including traction frame, spout, link means, braking single arm -drag, the traction frame lower extreme is equipped with the spout, and the spout is arranged in to link means one end head, and the braking single arm -drag is connected to the link means other end, and left and right coaster brake hub is connected respectively at both ends about the braking single arm -drag. Its simple structure need not the operating personnel handle and stops in the use, utilize simple mechanical transmission to turn into the brake force of brakeing the single arm -drag with the gravity of traction frame, realizes parking braking, convenient to use.
Description
Technical field
This utility model belongs to Ground and ensures special purpose device, a kind of device making trailer produce parking braking by simple and mechanical transmission.
Background technology
Trailer holding brake device, is mainly used in the cargo tow tractor on airport or railway station.During existing trailer parking, need operator to pull and pull the hand brake.Pulling the hand brake if operator's improper use is forgotten to pull, trailer continues to move ahead, and brings series of problems.
Utility model content
For the deficiencies in the prior art, the purpose of this utility model aims to provide a kind of automatic trailer parking device, it is to avoid need to pull the parking that pulls the hand brake when trailer uses.
For achieving the above object, this utility model adopts the following technical scheme that
A kind of automatic trailer parking device, including traction frame, chute, T-shaped linkage, braking torque arm；Traction frame lower end is provided with chute, and T-shaped linkage head is placed in chute, and bottom T-shaped linkage, two ends connect braking torque arm respectively, and braking torque arm connects left and right brake hub respectively.
Further, T-shaped linkage is provided with locking nut.
When traction frame traction seat after tractor is escaped by operator, slowly transfer, by action of gravity, T-shaped linkage head slide downward in chute, T-shaped linkage is moved, and compacting braking torque arm, it acts on left and right brake hub and produces parking braking effect.If long-time use causes the brake shoe plate abrasion in brake hub serious so that when braking effect is deteriorated, at this moment can regulate the locking nut on linkage so that linkage is elongated, thus can improve parking braking effect.
The beneficial effects of the utility model are: simple in construction, pull the hand brake without operator during use, utilize simple machine driving that the gravity of traction frame is converted into the brake force of braking torque arm, it is achieved parking braking, easy to use.
Accompanying drawing explanation
Fig. 1 is the front view of this utility model embodiment 1；
Fig. 2 is the structural representation of this utility model embodiment 1.
Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is further elaborated.
Embodiment 1
As shown in Figure 1-2, a kind of automatic trailer parking device, mainly it is made up of traction frame (1), chute (2), T-shaped linkage (3), locking nut (4), braking torque arm (5).Traction frame (1) lower end is provided with chute (2), T-shaped linkage (3) head is placed in chute (2), T-shaped linkage (3) is provided with locking nut (4), two ends, T-shaped linkage (3) bottom connect braking torque arm (5) respectively, and braking torque arm (5) connects left and right brake hub (6 and 7).
When the traction frame (1) traction seat after tractor is escaped by operator, slowly transfer, by action of gravity, T-shaped linkage (3) head is slide downward in chute (2), T-shaped linkage (3) is moved, compacting braking torque arm (5), acts on left and right brake hub (6 and 7) and makes it produce parking braking effect.If long-time use causes the brake shoe plate abrasion in brake hub serious so that when braking effect is deteriorated, at this moment can regulate the locking nut (4) on linkage so that linkage is elongated, thus can improve parking braking effect.
Claims (2)
1. an automatic trailer parking device, it is characterised in that include traction frame, chute, T-shaped linkage, braking torque arm；Traction frame lower end is provided with chute, and T-shaped linkage head is placed in chute, and bottom T-shaped linkage, two ends connect braking torque arm respectively, and braking torque arm connects left and right brake hub respectively.
Automatic trailer parking device the most according to claim 1, it is characterised in that T-shaped linkage is provided with locking nut.
