Abstract

A return device for controlling the steering wheel of a vehicle to return automatically during steering running. The problem of poor aligning ability that especially hydraulic power steering vehicle exists is solved, not only alleviateed driver's fatigue strength, the way sense of steering wheel when still can providing different steering angles simultaneously has improved the manipulation performance of vehicle.

Description

Steering control

The utility model relates to a kind of control vehicle bearing circle Steering control of return voluntarily in turning to driving process.

At present, the bearing circle aligning torque is to lean on the aligning torque of pivoted wheels on vehicle to pass to bearing circle by steering gear.But the vehicle aligning torque that has is big, and the vehicle aligning torque that has is little, and especially the hydraulic power steerig system is low to the transmission efficiency of bearing circle transmission aligning torque, and car load test return performance is lower than the return performance of standard machinery formula steering system.Still the Steering control class technical products that does not have at present independent control vehicle steering reversal.

The purpose of this utility model is for a kind of control vehicle bearing circle Steering control of return voluntarily in turning to driving process is provided, and it has solved the especially problem of hydraulic power steerig vehicle return performance difference.

The purpose of this utility model is achieved in that Steering control is installed on the drive link between bearing circle and deflector, and Steering control shell and car body are fixed, Steering control main shaft and drive link coaxial rotation.Steering control inside is made up of the return mechanism of two groups of unidirectional drive, and one group is the cw driving later of main shaft midway location, and another group drives for main shaft midway location conter clockwise later.Main shaft turns over midway location when any side is rotated, and the return mechanism that all can drive this side is with changeing, and the aligning torque of return mechanism makes steering swivel system produce aligning torque.

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is a front view; Fig. 2, Fig. 3 are the partial view of Fig. 1.

Among the figure: (1) main shaft, (2) the second from left level ring gear, (3) left finger, (4) left dial, (5) left limit shell, (6) left clockwork spring, (7) one-level passive tooth wheel shaft, (8) left end cap, (9) right secondary ring gear, (10) right finger, (11) right dial, (12) right limit shell, (13) right clockwork spring, (14) right end cap.

In Fig. 1, left finger (3) is installed on the left surface of the second from left level ring gear (2), and right finger (10) is installed on the right flank of right secondary ring gear (9).In Fig. 2, a N left side is a left clockwork spring (6) to the moment of torsion of left dial (4) when zero angle position.Left side finger (3) is stirred left dial (4) and is clockwise rotated when clockwise rotating; Left side finger (3) then deviates from left dial (4) when rotating counterclockwise, and left dial (4) is inoperative.In Fig. 3, the N right side is a right clockwork spring spring (13) to the moment of torsion of right dial (11) when zero angle position.Right finger (10) deviates from right dial (11) when clockwise rotating, and right dial (11) is inoperative; Right finger (10) is stirred right dial (11) and is rotated counterclockwise when rotating counterclockwise.

Steering control main shaft (1) is sleeved on the steerage gear bar, and locks with drive link, rotates synchronously.Left limit shell (5) and right limit shell (12) are fixed on the nonrotational part of car body.When drive link clockwise rotates, rotating torque passes to one-level passive tooth wheel shaft (7) by main shaft (1), one-level passive tooth wheel shaft (7) passes to moment respectively the second from left level ring gear (2) and right secondary ring gear (9) again, right finger (10) on the right secondary ring gear (9) is stirred right dial (11) and is rotated, right clockwork spring (13) is further screwed more, and aligning torque is just big more.And left finger (3) rotation direction on the second from left level ring gear this moment (2) deviates from mutually with left dial (4), so left dial (4) is inoperative; Then be that left dial (4) works when drive link rotates counterclockwise, and right dial (11) is inoperative.

The size of Steering control aligning torque depends on the initiation moment and the rigidity of left clockwork spring (6) and right clockwork spring (6).

Claims

1. the control vehicle bearing circle Steering control of return voluntarily in turning to driving process, it is characterized in that: two groups of identical return mechanisms of structure are respectively controlled Steering control main shaft cw return and conter clockwise return, and every group of return mechanism is made up of end cap, spring, dial and spacing shell.

2. Steering control according to claim 1 is characterized in that: the unidirectional rotation of the finger of installing on the ring gear that every group of return mechanism driven by reaction gear drives.

3. Steering control according to claim 1 is characterized in that: every group of return mechanism medi-spring acts between end cap and dial, and the dial return rotational limitation that is shaped on the effect of limiting stopper restraining spring on the spacing shell does not make main shaft surpass midway location.
