Traction frame for trailer

Abstract

The invention provides a traction frame for a trailer and relates to the technical field of traction frames. The traction frame for the trailer comprises a traction frame body, a traction plate and a buffering device; the traction frame body is a triangular frame body, the inside of the triangular frame body is fixedly connected with a stiffening beam, two angles of the triangular frame body are parallelly and fixedly connected with traction plates respectively, the outer side of each traction plate is provided with a limiting plate bracket, the other end of each traction plate is connected with a connection block, the two sides, forming the another angle, of the triangular frame body are connected with the buffering device, and the buffering device includes a mounting sleeve, a traction shaft and a compression spring; the end portion of the traction shaft is in threaded connection with a slotted nut, a retaining ring is arranged on the position, located on the outside of the mounting sleeve, of the traction shaft, the compression spring is arranged between the retaining ring and the mounting sleeve, and the other end of the traction shaft is connected with a traction hole. According to the traction frame, in the acceleration and deceleration processes, a vehicle body of the trailer keeps smooth and steady, and the braking technical effect is achieved when the trailer is parked.

Description

technical field [0001] The invention relates to the technical field of traction frames, in particular to a trailer traction frame. Background technique [0002] Trailers are widely used in the transportation industry. Generally, the tractor and the trailer are connected through the link on the tractor and the hook on the frame to transport large-tonnage goods. However, the existing trailer structure has no buffer spring. There is no parking limit plate, but the current traction frame structure does not have a buffer spring. When the trailer is running, acceleration and deceleration will make the trailer body unstable, and there is no parking limit plate, so it cannot be braked when the trailer is parked. Contents of the invention [0003] Aiming at the defects in the prior art, the present invention provides a trailer traction frame, which solves the lack of a buffer device in the prior art, which causes the trailer body to be unstable when the trailer is accelerating or d...
