Semi-trailer traction saddle

Abstract

The invention provides a semi-trailer traction saddle. The semi-trailer traction saddle is characterized in that a left frame support beam and a right frame support beam are symmetrically arranged outside a frame, a left saddle bracket and a right saddle bracket are correspondingly connected onto the left frame support beam and the right frame support beam through bolts I, and a saddle is connected onto the left saddle bracket and the right saddle bracket; a left saddle inclined block and a right saddle inclined block are correspondingly arranged on the inner sides of the left saddle bracket and the right saddle bracket, the bottom surface of the left saddle inclined block and the bottom surface of the right saddle inclined block are attached to the plane of the frame, the inclined plane of the left saddle inclined block and the inclined plane of the right saddle inclined block are attached to the inner inclined plane of the left saddle bracket and the inner inclined plane of the right saddle bracket respectively, and the saddle inclined blocks are connected with the left saddle bracket and the right saddle bracket through transverse bolts II respectively. According to the semi-trailer traction saddle, a saddle mounting plate is omitted, the saddle support bodies, namely the saddle brackets, are connected with the frame support beams through the bolts; in a use process, vertical load applied to the saddle is transmitted to the frame through the saddle brackets and the saddle inclined blocks, and the frame and the frame support beams bear vertical pressure; stress generated through height difference clearance is reduced while the cost is reduced, and connection safety and use safety of the saddle are guaranteed.

Description

technical field [0001] The invention relates to a traction device for a semi-trailer vehicle, in particular to a fixed saddle traction saddle. Background technique [0002] Application number: 200620087879.9 Application date: 2006-08-17 Automobile saddle position adjustment device. Composition, the saddle is fixed on the saddle support body with a slideway, the saddle support body is set on the saddle guide rail through the slideway, a number of limit grooves are arranged on the saddle guide rail, and one end of the pin lock is stuck on the saddle guide rail The other end is connected to the zipper in the limit slot of the lock pin; the rear end of the lock pin is equipped with a return spring, which can play a position limit role. The basic principle of the Picatinny structure is adopted to fix the saddle on the saddle support body with slides. The saddle support body can only slide forward and backward on the saddle guide rail. There are many limit positions on the saddle...

Problems solved by technology

In addition, the use of saddle rails is also prone to failure, which is unfavorable to the use of saddles

[0004] In addition, during the manufacturing and assembly process of the frame, there is a height difference between the support beam and the frame, and the saddle mounting plate is used to adjust the height difference, but this will cause the saddle support (bracket) to be fixed on the frame through the saddle mounting plate After being put on, there is stress caused by the height difference gap, which is a cause of damage to the saddle mounting plate; during use, the saddle support (bracket) and the saddle mounting plate are prone to cracking and other damages, resulting in quality claims

[0005] The function of the saddle mounting plate is only to facilitate the installation of the saddle on the frame and to adjust the mounting height of the saddle. The use of the saddle mounting plate increases the manufacturing cost of the saddle
