Stability is improved excessively curved when, the design of current Tiebar structure is unreasonable, and performance-adjustable is poor, and pull bar is under mechanical shock
Connection is unstable.
In order to solve the above problems, the patent of patent No. CN 201620519171.X utility model discloses a kind of extension
Automobile-used torque arm, for fixing and adjusting the suspension of trailer railway carriage, including pull bar, the connector positioned at pull bar both ends and it is located at
Engaging component between pull bar and connector, engaging component include 2 symmetrical engaging body and engaging bolt, and engaging bolt is used for
Engaging body is fixed on pull bar, above-mentioned torque arm is by changing the attachment structure between pull bar and connector, to trailer railway carriage
Only need to be adjusted the section components of torque arm and can achieve the goal when safeguarding with adjustment, without carrying out Trailer type frame for use in vehicle
Extensive dismounting, time saving and energy saving, reduction maintenance cost, but the stress of torque arm ensures that reliability is low, together against engaging component
When it does not ensure that the end face of the connector positioned at pull bar both ends is in the same plane in the process that uses of assembling, practicality
It is low.
The content of the invention
In order to solve the above-mentioned technical problem, the utility model provides a kind of simple in construction, and reliability is high, and practical
Semi-trailer suspension pull bar.
The utility model is realized using following technical scheme：Described semi-trailer suspension pull bar, including connecting rod and
It is arranged on the connector at the connecting rod both ends, it is characterised in that the connecting rod includes the first cylinder, first cylinder
Both ends are symmetrically arranged with the second cylinder, and the diameter of second cylinder is less than the diameter of the first cylinder, in the axial direction equidistantly
The bar shaped boss of predetermined number is disposed with, the second cylinder is arranged in equal spacing with the through hole I of predetermined number in the axial direction, described
Connector includes sleeve pipe and the drawhead being arranged on sleeve pipe, the bar shaped provided circumferentially about for having predetermined number of the inwall of described sleeve pipe
Groove, the shape of the strip groove are adapted with bar shaped boss, and rectangular slab, the rectangle are symmetrically arranged with the outer wall of sleeve pipe
The through hole II of predetermined number is provided with plate, the through hole II and through hole I are adapted, on through hole I and through hole II
It is equipped with the fastener for sleeve pipe and the second cylinder to be connected.
Further, the drawhead is connected by the form of welding with sleeve pipe.
Further, the fastener includes screw bolt and nut.
Further, the rectangular slab is arranged on sleeve pipe by the form of welding.
Usefulness of the present utility model is：On second cylinder on bar shaped boss and sleeve pipe strip groove setting, ensure
The reliable location of connecting rod and connector, so as to ensure that the end face of drawhead is in the same plane；Through hole on sleeve pipe
II and second through hole I on cylinder set, ensure that being reliably connected for connecting rod and connector, bigger pulling force can be born,
Through hole I and through hole II are arranged to multiple simultaneously so that pull bar can adjust pull bar itself according to specific working condition
Length, it is practical.
