Abstract
The passive steeraxle assembly of the one that the utility model provides, comprise H-girder, knuckle assembly and pairing cylinder flower tooth, described H-girder comprises the first attachment face, described knuckle assembly comprises steering swivel, stub, described steering swivel comprises the second attachment face, described pairing cylinder flower tooth comprises cylinder flower tooth, lower cylinder flower tooth, described upper cylinder flower tooth is fixedly connected with described first attachment face, described lower cylinder flower tooth is fixedly connected with described second attachment face, and described upper cylinder flower tooth is engaged by flower tooth with described lower cylinder flower tooth.When chaufeur low speed rotation to time, vehicle can produce around instantaneous centnifugal force, a side-force reaction is produced at the contact point on wheel and ground, due to the existence of kingpin caster angle, lateral reaction forms the moment of rotating around stub to wheel, after this moment overcomes the friction moment of cylinder flower between cog, lower cylinder flower tooth can rotate around upper cylinder flower tooth, make wheel turn over certain angle around stub, prevent ovdersteering and deficiency.
Description
Technical field
The utility model relates to a kind of vehicle transmission gear, particularly a kind of passive steeraxle assembly.
Background technology
At present, the rear axle steering of multiple-axle vehicle generally adopts mechanical-hydraulic servo-steering or automatically controlled hydro-steering two kinds of modes, mechanical-hydraulic servo-steering relies on engine power to drive oil pump, energy consumption is higher, complex structure, the maintenance in later stage needs cost high, and a whole set of oil circuit often keeps high pressure conditions, and service life is short; Automatically controlled hydro-steering and front steering axle are not mechanically connected, realized the coordination follow-up steering of rear axle and front steering axle by sensor and electron steering, to the serviceability of actuating unit hydraulic actuating cylinder require high compared with high, complex structure, cost, to take space, chassis large.Therefore exploitation has that structure is simple, tooling cost is low, it is little, extremely urgent to the steeraxle of the advantages such as working environment adaptability is strong to take up room.
Utility model content
In order to solve the problems of the technologies described above, the utility model provides a kind of passive steeraxle assembly adopting pairing cylinder flower tooth, and its structure is simple, it is little to take up room, cost is low, can adapt to severe operating environment, to meet the requirement of superimposed trailer and motor omnibus.
The passive steeraxle assembly of the one that the utility model provides, comprise H-girder, knuckle assembly and pairing cylinder flower tooth, described H-girder comprises the first attachment face, described knuckle assembly comprises steering swivel, stub, described steering swivel comprises the second attachment face, described pairing cylinder flower tooth comprises cylinder flower tooth, lower cylinder flower tooth, described upper cylinder flower tooth is fixedly connected with described first attachment face, described lower cylinder flower tooth is fixedly connected with described second attachment face, and described upper cylinder flower tooth is engaged by flower tooth with described lower cylinder flower tooth.
In such scheme, described first attachment face is provided with knock hole, and described upper cylinder flower tooth is located by pin, and further described upper cylinder flower tooth and described first attachment face is fixed by welding.
In such scheme, described lower cylinder flower tooth is fixedly connected with by pin with described second attachment face.
In such scheme, described stub and described H-girder interference fit, the upper end of described stub is processed with one section of blind hole, is placed with a preloading spring in described blind hole.
In such scheme, the length of described preloading spring is greater than the length of described blind hole.
The beneficial effect that the utility model brings: when chaufeur low speed rotation to time, vehicle can produce around instantaneous centnifugal force, a side-force reaction is produced at the contact point on wheel and ground, due to the existence of kingpin caster angle, lateral reaction forms the moment of rotating around stub to wheel, after this moment overcomes the friction moment of cylinder flower between cog, lower cylinder flower tooth can rotate around upper cylinder flower tooth, make wheel turn over certain angle around stub, prevent ovdersteering and deficiency; Under initial tension of spring effect, pairing cylinder flower tooth can better engage; Relative to the steeraxle of hydraulic steering cylinder composition, a pair cylinder flower dentine amount is light, complete vehicle quality is lightened, is conducive to reducing oil consumption.

Specific embodiment
Below in conjunction with accompanying drawing and specific embodiment, the utility model is further described, but protection domain of the present utility model is not limited to this.
As shown in Fig. 1 to 7, the utility model comprises H-girder 3, knuckle assembly 1 and pairing cylinder flower tooth 2, described H-girder 3 comprises the first attachment face 9, described knuckle assembly 1 comprises steering swivel 6, stub 5, described steering swivel 6 comprises the second attachment face 8, described pairing cylinder flower tooth 2 comprises cylinder flower tooth 11, lower cylinder flower tooth 7, described upper cylinder flower tooth 11 is fixedly connected with described first attachment face 9, described lower cylinder flower tooth 7 is fixedly connected with described second attachment face 8, and described upper cylinder flower tooth 11 is engaged by flower tooth with described lower cylinder flower tooth 7.Solve problem be: when chaufeur low speed rotation to time, vehicle can produce around instantaneous centnifugal force, a side-force reaction is produced at the contact point on wheel and ground, due to the existence of kingpin caster angle, lateral reaction forms the moment of rotating around stub to wheel, after this moment overcomes the friction moment of cylinder flower between cog, lower cylinder flower tooth can rotate around upper cylinder flower tooth, make wheel turn over certain angle around stub, prevent ovdersteering and deficiency.
Further, described first attachment face 9 is provided with knock hole, and described upper cylinder flower tooth 11 is located by pin 10, and is further fixedly connected with described first attachment face 9 by described upper cylinder flower tooth 11 by welding.Be conducive to cylinder flower tooth accurately to locate on H-girder, and reliably connect.
Further, described lower cylinder flower tooth 7 is fixedly connected with by pin with described second attachment face 8.Be conducive to lower cylinder flower tooth accurately to locate on steering swivel 6, and be beneficial to knuckle assembly dismounting.
Further, described stub 5 and described H-girder 3 interference fit, the upper end of described stub 5 is processed with one section of blind hole, a preloading spring 4 is placed with in described blind hole, the length of described preloading spring 4 is greater than the length of described blind hole, spring compresses and produces predetermincd tension in blind hole, and under initial tension of spring effect, pairing cylinder flower tooth can better engage.
Described embodiment be the utility model preferred embodiment; but the utility model is not limited to above-mentioned embodiment; when not deviating from flesh and blood of the present utility model, any apparent improvement that those skilled in the art can make, replacement or modification all belong to protection domain of the present utility model.
