Abstract
The invention discloses a kind of steering column band countershaft assemblies, including electric power-assisted steering tubular column assembly, countershaft assembly, inner sleeve and outer sleeve, it is bolted to connection between the electric power-assisted steering tubular column assembly and countershaft assembly, inner sleeve is connect with electric power-assisted steering tubular column assembly by three hexagon socket head cap screws, outer sleeve is sheathed on inner sleeve, and is locked between outer sleeve and inner sleeve by bolt.This invention removes because of fit-up gap bring axial force, steering feel is improved, the security performance of vehicle is improved.
Description
Technical field:
The present invention relates to a kind of steering column band countershaft assemblies.
Background technique:
With the raising of auto industry level, the steering system form of present more and more automobiles becomes electricity from hydraulic booster
Dynamic power-assisted, the steering system of such structure had not only improved the handling of vehicle, but also reduced integral vehicle cost, so obtaining quickly
It is widely applied.
In the prior art, since some vehicle steering column arrangement spaces are larger, lead to the arrangement space of jackshaft
Limited, so that structure can only be designed to that length is fixed, but the characteristics of such structure, is: since there are certain productions one for vehicle
Cause property, components can not eliminate the axial force of steering system after assembly is completed, on the one hand will cause torque wave when steering
It is dynamic, while there is also some potential safety problemss.
Summary of the invention:
The present invention provides a kind of steering column band countershaft assembly, by changing the structure of jackshaft, to allow to disappear
Except because of fit-up gap caused by vehicle component consistency difference.
The technical solution adopted in the present invention has: a kind of steering column band countershaft assembly, including electric power steering pipe
Column assembly, countershaft assembly, inner sleeve and outer sleeve pass through between the electric power-assisted steering tubular column assembly and countershaft assembly
Bolt is fixedly connected, and inner sleeve is connect with electric power-assisted steering tubular column assembly by three hexagon socket head cap screws, and outer sleeve is sheathed on
On inner sleeve, and locked between outer sleeve and inner sleeve by bolt.
Further, fixation hole, and consolidating on inner sleeve are equipped on the side wall of the inner sleeve with the side wall of outer sleeve
Determine hole to connect with the fixation hole on outer sleeve.
Further, the electric power-assisted steering tubular column assembly is angle adjustable structure, and angle adjustable is 18 degree.
Further, the sensor on the electric power-assisted steering tubular column assembly is non-contact torque sensor.
Further, the deceleration mechanism in the electric power-assisted steering tubular column assembly is worm gear type, and reduction ratio is
16.5。
Further, the motor rated power in the electric power-assisted steering tubular column assembly is 290w.
Further, the structure of the countershaft assembly is adjustable, adjustment length 28mm.
The invention has the following beneficial effects: this invention removes because of fit-up gap bring axial force, steering is improved
Feel improves the security performance of vehicle.
Detailed description of the invention:
Fig. 1 is explosive view of the present invention.
Fig. 2 is installation diagram of the present invention.
Fig. 3 is cross-sectional view of the present invention.
Specific embodiment:
