The mechanism for adjusting the meshing clearance between the gear and the rack of the automobile steering device has the remarkable advantage that the meshing clearance between the gear and the rack is automatically adjusted.
Description
Technical field:
The present invention relates to a kind of Automotive Steering Technology, particularly a kind of regulating mechanism of automobile steering device gear tooth bar back lash.
Background technique:
The back lash of gear rack mechanical steering gear is very large to the performance impact of commutator, and back lash is too small, hard steering, excesssive gap, and commutator there will be abnormal sound.Regulating mechanism between traditional rack and pinion engagement, can only ensure the normal back lash at automobilism initial stage, through after a period of time, when adjustment body wear extent acquires a certain degree, causing back lash excessive, there is abnormal sound in commutator, comfort reduces, and the commutator life-span declines; Solution route solves by exchanging integrated regulation back lash, and now need to exchange integrated model dismounting and change adjustment body, lost time is many, costly.
Summary of the invention:
The object of the invention is to provide a kind of regulating mechanism with a kind of automobile steering device gear tooth bar back lash of adjustment automobile steering device gear tooth bar back lash automatically.
The technological scheme realizing the object of the invention is a kind of regulating mechanism of automobile steering device gear tooth bar back lash, comprise adjustment body, housing, adjustment plug screw and lock nut, it is characterized in that: described adjustment plug screw is a tubular, the cylindrical shell of described adjustment plug screw is provided with the outside thread matched with the tapped hole of housing and lock nut, stationary. platen is provided with successively from left to right in the cylindrical shell of described adjustment plug screw, counterbalance spring and coupling body, the left end of described stationary. platen is cylinder, the right-hand member of this cylinder is stepped cylinder, cylinder between described adjustment body right side and described stationary. platen left side and stepped cylinder are arranged with dynamic pressure plate and butterfly spring respectively, the screw thread of self-locking nut and described stationary. platen cylinder left end matches, described counterbalance spring is open annular plate, the left side of this annular slab is plane, right side is inner high and outer end the is low conical surface, the internal surface of annular slab opening both sides is respectively equipped with the otic placode mutually staggered, these two otic placodes are respectively provided with a pin-and-hole matched with pin, pin-and-hole on two otic placodes coincides when counterbalance spring mouth closes, the left end ring surface of described coupling body is the conical surface matched with the right-hand member ring surface of counterbalance spring, gap is had between the right side of described dynamic pressure plate and the left side of described stationary. platen stepped cylinder, the size of this gap is the normal back lash of gear rack.
The present invention has the remarkable advantage of adjustment rack meshing clearance automatically compared with the prior art.
Accompanying drawing illustrates:
Fig. 1 is existing rack of steering meshing gap adjusting mechanism schematic diagram; Fig. 2 is rack meshing clearance regulating mechanism schematic diagram of the present invention; Fig. 3 is the plan view of counterbalance spring; Fig. 4 is the A-A turnover sectional view of Fig. 3.
Embodiment:
The present invention is directed to the defect that existing meshing gap adjusting mechanism does not have automatic regulating gap, the spring 7 in its regulating mechanism, adjustment plug screw 3 are improved.Technological scheme of the present invention is, the left end of stationary. platen 6 is cylinder, be stepped cylinder 12 at the right-hand member of this cylinder, stepped cylinder between adjustment body 1 right side and described stepped cylinder left side is arranged with dynamic pressure plate 8, stepped cylinder is arranged with butterfly spring 7, self-locking nut 9 matches with the outside thread of cylinder, the adjustment plug screw 3 of tubular, this adjustment plug screw cylindrical shell is provided with the outside thread matched with the screw thread on housing 10 hole and lock nut, the right side of the stationary. platen in described adjustment plug screw cylinder is provided with counterbalance spring 5 and coupling body 4, described counterbalance spring is open annular plate, the left side of this open annular plate is that plane contacts with described stationary. platen right side, right side is the conical surface of interior high outer bottom, described coupling body left side is the conical surface matched with the described counterbalance spring right-hand member conical surface, the both sides inwall of described counterbalance spring opening is respectively equipped with an otic placode 16, 13, these two otic placodes stagger mutually, two otic placodes are respectively equipped with a pin-and-hole 14, 15 and pin is sliding joins, described two pin-and-holes coincide when counterbalance spring closes.
The principle of assembling method of the present invention and automatically adjustment rack meshing clearance, before assembling, first butterfly spring, dynamic pressure plate to be enclosed within respectively on the stepped cylinder of stationary. platen and cylinder and to screw on self-locking nut 9, the degree of screwing should make there is gap between dynamic pressure plate and stepped cylinder, this gap is normal gear rack 11 back lash, then counterbalance spring is made to close, penetrate in two lug plate holes of counterbalance spring with pin, after making its closed state fixing, counterbalance spring and coupling body are placed in adjustment plug screw cylinder and shell combination, finally tighten lock nut 2.Now counterbalance spring is locked, pin in counterbalance spring lug plate holes need be pulled out, so that after adjustment body is worn, compensate back lash, compensation principle is, after adjusting overall wear, butterfly spring expands, and reduce the axial pressure that counterbalance spring applies, counterbalance spring is just dehisced, producing axial force makes stationary. platen, dynamic pressure plate and adjustment body move to left, and belleville spring and counterbalance spring are in state of equilibrium.For this reason, the end cap of adjustment plug screw should arrange the auxiliary hole taking out pin, and after removing pin, blocked by this auxiliary hole with sealer, this auxiliary hole also can be a tapped hole matched with screw.
This counterbalance spring and coupling body structure have the remarkable advantage of adjustment back lash automatically.
