Abstract

The invention relates to an automobile brake stay rope joint device comprising a steel wire rope, wherein the steel wire rope passes through a sleeve, and the end of the steel wire rope is connected with a pull head. The automobile brake stay rope joint device is characterized in that the end of the sleeve is connected with one end of a pipe joint, the other end of the pipe joint is provided with two stages of steps, the diameter of the first-stage step is smaller than that of the second-stage step, and a boss is formed in the peripheral direction of the second-stage step relative to the first-stage step; and the end of the first-stage step is fixedly provided with an expansion fastener through a mounting seam allowance, and a rubber ring is arranged between the expansion fastener and the end surface of the second-stage step. The expansion fastener comprises a sleeve body provided with an open slot and expansion fins uniformly distributed on the outer surface of the sleeve body; and the ends of the expansion fins, far away from the pipe joint, are fixedly connected with the sleeve body, and an expansion gas is formed between the sleeve body and each of the ends of the expansion fins, near the pipe joint. The automobile brake stay rope joint device provided by the invention can be used for reducing noise and vibration and better protecting a stay rope while playing a fastening role.

Description

Braking automobile cable connector device

Technical field

The present invention relates to a kind of braking automobile cable connector device, especially a kind of automobile hand brake brake line piecing devices.

Background technique

At present, general automobile hand brake brake line joint all is to have at one a metal clamps is installed on the barrel joint, inside and outside drag-line passes operator cabin, during attachment hole, fixes with metal clamps or nut.The major defect that the cable connector of this structure exists is: trouble is installed, and fixing unreliable, the metal impact friction produces noise, of long duration nut or all easy deformation even damages of metal clamps, the very big like this rate of fault that increases drag-line.

Summary of the invention

The objective of the invention is to overcome the deficiency that exists in the existing technology, a kind of braking automobile cable connector device is provided, when playing the role of fastening, can also the noise abatement damping, the better protect drag-line.

According to technological scheme provided by the invention, said braking automobile cable connector device comprises wire rope, and the steel wire penetrating sleeve pipe connects the pulling force head in the end of wire rope; It is characterized in that: the end of said sleeve pipe is connected with an end of pipe joint, and the other end of pipe joint is provided with the two-stage step, and the diameter of first order step is less than the diameter of second level step, and second level step forms boss with respect to the circumferencial direction of first order step; The end of said first order step is provided with rubber ring through seam fixed expansion fastening piece is installed between the end face of expansion fastener and second level step.

Said expansion fastener comprises the body that is provided with opening slot and the expansion wing that is evenly distributed on the cover external surface; The said expansion wing is fixedly connected with body away from an end of pipe joint, and the expansion wing is near forming expansion space between end of pipe joint and the body.

Braking automobile cable connector device of the present invention can also the noise abatement damping when playing the role of fastening, the better protect drag-line.

Embodiment

Below in conjunction with concrete accompanying drawing the present invention is described further.

Like Fig. 1 ~ shown in Figure 4: said braking automobile cable connector device comprises pulling force head 1, wire rope 2, expansion fastener 3, rubber ring 4, pipe joint 5, sleeve pipe 6, first order step 7, second level step 8, body 31, the expansion wing 32, opening slot 33 etc.

As shown in Figure 1, the present invention includes wire rope 2, wire rope 2 passes sleeve pipe 6, connects pulling force head 1 in the end of wire rope 2; The end of said sleeve pipe 6 is connected with an end of pipe joint 5, and the other end of pipe joint 5 is provided with the two-stage step, and the diameter of first order step 7 is less than the diameter of second level step 8, and second level step 8 forms boss with respect to the circumferencial direction of first order step 7; The end of said first order step 7 is provided with rubber ring 4 through seam fixed expansion fastening piece 3 is installed between the end face of expansion fastener 3 and second level step 8;

Like Fig. 2 ~ shown in Figure 4; Said expansion fastener 3 comprises the body 31 that is provided with opening slot 33 and the expansion wing 32 that is evenly distributed on body 31 outer surfaces; The said expansion wing 32 is fixedly connected with body 31 away from an end of pipe joint 5, and the expansion wing 32 is near forming expansion space between end of pipe joint 5 and the body 31;

The material of said expansion fastener 3 is 65Mn, has better elastic and wear resistance.

Rubber ring 4 of the present invention can play and prevent the loosening and buffer shaft of expansion fastener 3 to function of friction, reduces vibrations, reduces noise simultaneously; Inside and outside drag-line passes operator cabin during attachment hole; Expansion fastener 3 is squeezed and passes attachment hole; Pass after the attachment hole expansion wing 32 resilience at once on the expansion fastener 3 and return original position; Attachment hole is stuck between the end face of second level step 8 of expansion fastener 03 and pipe joint 5, reaches fastening effect; At this moment; The end of rubber ring 4 step 8 in the second level; Because rubber ring 4 itself is soft wear-resisting to have better elastic, the friction vibrations that can the buffer mechanism motion when rubber ring 4 cooperates the inside and outside attachment hole of expansion fasteners 3 fastening operator cabins produce reduce noise.
