Abstract

The invention discloses a damping device and method for a rack and pinion steering gear. The rack and pinion steering gear comprises a transverse pull rod and a ball seat matched with a ball head of the transverse pull rod, and the ball seat is connected with a rack. The damping device is a damping buffer ring arranged at the end, connected with the ball seat, of the rack. When the steering gear is in a limit position, the damping buffer ring absorbs and releases impact shock generated by impact between the ball head and a limiting face, not only can steering comfortableness be improved, but also steering abnormal noise can be reliably reduced, and meanwhile the service life of the steering gear can be prolonged.

Description

Technical field
The present invention relates to steering gear, be specifically related to rack and pinion steering gear damping device and shock-dampening method.
Background technology
Rack and pinion steering gear, when normal operation position, will not produce abnormal sound or impact endurance test shock.But During the state that steering wheel is killed, rack and pinion steering gear is in maximal work location status, track rod Bulb and confined planes can produce shock;Bulb and confined planes shock can produce impact endurance test shock and abnormal sound, impact Shake and be delivered on steering wheel by the tooth bar connected with track rod, not only can affect and turn to comfortableness, And the service life of steering gear can be affected.
Summary of the invention
It is an object of the invention to overcome the deficiencies in the prior art, it is provided that when reducing steering gear maximal work position Impact endurance test shock, improve and turn to rack and pinion steering gear damping device and the shock-dampening method of comfortableness.
To achieve these goals, the technical solution used in the present invention is:
This rack and pinion steering gear damping device, the bulb including drag link and with described drag link coordinates Ball seat, described ball seat and tooth bar connect, and described damping device is to be located at described tooth bar and the connection of described ball seat Damping, buffering ring on end, one end.
Described damping, buffering ring is plastic hoop.
Described damping, buffering ring inwall is provided with projection friction tight with described tooth bar.
Described damping, buffering ring is provided with opening.
Described tooth bar is provided with the mounting groove installing described damping, buffering ring, described damping, buffering ring side and institute State ball seat contact.
Described projection is pyramidal structure.
This rack and pinion steering gear shock-dampening method, utilizes above-mentioned rack and pinion steering gear damping device Realizing, particularly as follows: damping, buffering ring is contained in the mounting groove of tooth bar, damping, buffering ring side contacts with ball seat; Rack and pinion steering gear and steering wheel connect, and during motor turning, when steering wheel is in the state of killing, horizontal draw The bulb of bar and confined planes clash into the impact produced and vibrations are delivered on tooth bar, by the damping, buffering on tooth bar Ring absorbs and decomposes, and makes the impact endurance test shock being delivered on steering wheel be greatly reduced, and impact abnormal sound reduces, and improves and turns To comfortableness.
It is an advantage of the current invention that: this rack and pinion steering gear damping device and shock-dampening method, in steering gear When being in extreme position, damping, buffering ring absorbs release bulb and confined planes clashes into the impact endurance test shock produced, no It is only capable of raising and turns to comfortableness, and can reliably reduce and turn to abnormal sound, steering gear can be extended simultaneously Service life.

Labelling in above-mentioned figure is:
1, tooth bar, 2, drag link, 3, damping, buffering ring, 4, protruding, 5, opening, 6 tooth bar blocks.
Detailed description of the invention
Below against accompanying drawing, by the description to optimum embodiment, the detailed description of the invention of the present invention is made into One step detailed description.
As shown in Figure 1-Figure 3, this rack and pinion steering gear damping device, draws including drag link 2 and with horizontal The ball seat that the bulb of bar 2 coordinates, ball seat and tooth bar 1 connect, and damping device is for being located at tooth bar 1 and ball seat company The damping, buffering ring 3 on end, one end connect.Rack and pinion steering gear and steering wheel connect, during motor turning, When steering wheel is in the state of killing, and drag link 2 is in extreme position, and bulb and the confined planes of drag link 2 hit Impact and the vibrations of hitting generation are delivered on tooth bar 1, i.e. the bulb of drag link 2 clashes into damping, buffering ring 3 He Impact and vibrations that spacing tooth bar block 6 produces are delivered on tooth bar 1, by the damping, buffering ring 3 on tooth bar 1 Absorbing and decompose, make the impact endurance test shock being delivered on steering wheel be greatly reduced, impact abnormal sound reduces, it is possible to greatly Ground raising turns to comfortableness.
Damping, buffering ring 3 is plastic hoop.Damping, buffering ring 3 is made up of PA66 plastic material, and shock resistance shakes Ability is strong, it is possible to play preferable shock absorbing effect.
Damping, buffering ring 3 inwall is provided with friction tight with tooth bar 1 protruding 4.Preferably protruding 4 is pyramidal structure. Protruding 4 are evenly distributed on damping, buffering ring 3 inwall.Multiple protruding 4 contact with tooth bar 1, it is possible to uniformly Fast cache is delivered to the impact endurance test shock on tooth bar 1, improves tooth bar 1 and the service life of drag link 2.
Damping, buffering ring 3 is provided with opening 5.Opening 5 is easy to the assembling of damping, buffering ring 3.
Tooth bar 1 is provided with the mounting groove installing damping, buffering ring 3, and damping, buffering ring 3 side contacts with ball seat. Damping, buffering ring 3 is arranged in mounting groove, contacts with ball seat, it is possible to what reliable quickly absorption passed over rushes Hit vibrations, reduce impact endurance test shock with express delivery.
This rack and pinion steering gear shock-dampening method, utilizes above-mentioned rack and pinion steering gear damping device Realize, particularly as follows: damping, buffering ring 3 is contained in the mounting groove of tooth bar 1, damping, buffering ring 3 side and ball Seated connection touches;Rack and pinion steering gear and steering wheel connect, and during motor turning, kill shape when steering wheel is in State, the bulb of drag link 2 clashes into damping, buffering ring 3 and the impact of tooth bar block 6 generation and vibrations are delivered to On tooth bar 1, absorbed decomposition by the damping, buffering ring 3 on tooth bar 1, make the impact shake being delivered on steering wheel Moving and be greatly reduced, impact abnormal sound reduces, and improves and turns to comfortableness.
This rack and pinion steering gear damping device and shock-dampening method, when steering gear is in extreme position, subtract Shake buffering ring 3 absorb release bulb and confined planes clash into produce impact endurance test shock, can not only improve turn to easypro Adaptive, and can reliably reduce and turn to abnormal sound, the service life of steering gear can be extended simultaneously.
Obviously the present invention implements and is not subject to the restrictions described above, as long as have employed the method structure of the present invention Think the improvement of the various unsubstantialities carried out with technical scheme, all within protection scope of the present invention.
