Abstract

Facilitating installation binodal shaft coupling, including double end section fork (1) and single-unit fork (2) the utility model discloses a kind of；The middle part of the double end section fork (1) is the middle seat (11) of cylinder, and middle seat (11) both sides are symmetrically arranged with the section fork ear A (12) of arc-shaped；The single-unit fork (2) bottom is cylindrical base (21), and pedestal (21) side is equipped with the section fork ear B (22) of arc-shaped；The section fork ear B (22) that the section fork ear A (12) of the double end section fork (1) both sides pitches (2) with single-unit respectively is flexibly connected.Utility model greatly reduces difficulty of processing, and stock utilization is high, improves machining accuracy and processing efficiency, also there is good mechanical strength simultaneously, can effectively ensure that the essence of the section fork phase angle at binodal shaft coupling both ends, structure are reliable, low manufacture cost is easy to industrialized production.

Description

It is a kind of to facilitate installation binodal shaft coupling

Technical field

The utility model is related to universal joint arts more particularly to a kind of facilitate to install binodal shaft coupling.

Background technology

In automobile steering system, when spatial position angle is larger, single gimbal structure, which is susceptible to, to be turned to clamping stagnation, turns round Square transmission efficiency is low, turns to the problem of endurance quality difference, thus using can arbitrarily devised phase angle binodal shaft coupling just It is very necessary.

But the double end section of existing binodal shaft coupling fork generally use adds the mode that two single-unit forks weld or rivet Work forms.This binodal coupler structure intensity is low, and since machining accuracy easilys lead to the section at binodal shaft coupling both ends The precision of fork phase angle, which is unable to get, to be effectively ensured, and eventually leads to steering mechanism and transmission exception occurs, torque transmission efficiency is low Under situation.

Utility model content

Facilitating installation binodal shaft coupling the purpose of the utility model is to provide a kind of.The utility model has good Mechanical strength can effectively ensure that the precision of the section fork phase angle at binodal shaft coupling both ends.

Technical solutions of the utility model：It is a kind of to facilitate installation binodal shaft coupling, including double end section fork and single-unit fork；It is described double The middle part of cephalomere fork is the middle seat of cylinder, and middle seat both sides are symmetrically arranged with the section fork ear A of arc-shaped；Single-unit fork bottom is Cylindrical base, pedestal side are equipped with the section fork ear B of arc-shaped；The section fork ear A of double end section fork both sides is pitched with single-unit respectively Section fork ear B flexible connection.

It is offered on aforementioned section fork ear A and offers bearing hole B on bearing hole A, the section fork ear B.

Aforementioned binodal shaft coupling further includes cross axle, section fork ear A and section fork ear B by bearing hole A, bearing hole B (23) and Cross axle is flexibly connected.

Compared with prior art, the utility model greatly reduces difficulty of processing, and stock utilization is high, improves processing essence Degree and processing efficiency, while also there is good mechanical strength, it can effectively ensure that the section fork phase angle at binodal shaft coupling both ends The essence of degree, structure is reliable, and low manufacture cost is easy to industrialized production.

Description of the drawings

Fig. 1 is the structural schematic diagram of the utility model.

Label in attached drawing be：1- double end sections are pitched, 2- single-units fork, 3- cross axles, seat in 11-, 12- section fork ear A, 13- axis Bearing bore A, 21- pedestal, 22- section fork ear B, 23- bearing holes B.

Specific implementation mode

The utility model is described further with reference to the accompanying drawings and examples, but is not intended as limiting the utility model The foundation of system.

Embodiment 1.

It is a kind of to facilitate installation binodal shaft coupling, as shown in Figure 1, including double end section fork 1 and single-unit fork 2；The double end section fork 1 Middle part be cylindrical middle seat 11,11 both sides of middle seat are symmetrically arranged with the section fork ear A12 of arc-shaped；The single-unit pitches 2 bottoms For cylindrical base 21,21 side of pedestal is equipped with the section fork ear B22 of arc-shaped；The double end section pitches A12 points of the section fork ear of 1 both sides It is not flexibly connected with the section fork ear B22 of single-unit fork 2.

It is offered on the section fork ear A12 and offers bearing hole B23 on bearing hole A13, the section fork ear B22.

The binodal shaft coupling further includes cross axle 3, and section fork ear A12 and section fork ear B22 pass through bearing hole A13, bearing hole B23 and cross axle 3 are flexibly connected.

In use, two single-unit forks 2 can pass through 3 activity of cross axle.

Double end section fork 1 and single-unit fork 2 are carried out quick and easy for installation by cross axle 3.
