Abstract
The present invention relates to a kind of steering shaft packing seal assembly, include packing seal, packing seal supporting seat, bearing, cavernous body and lining; Described packing seal is circular, and the via hole junction on packing seal and body dash board is provided with the sealed groove of annular, and sealed groove fits in the inner side of body dash board; Packing seal supporting seat is installed on packing seal and is positioned at the outside that body front wall intralamellar part divides; Bearing, cavernous body and lining are all positioned at the inside of packing seal circular ring structure, are followed successively by bearing, cavernous body and lining from bottom to up.
Description
Technical field
The invention belongs to the sealing element of deflector and vehicle body junction, specifically refer to a kind of steering shaft packing seal assembly.
Background technology
Steering shaft packing seal assembly is a vitals of car steering tube column and front panel junction, how reasonably to design packing seal, it is made to turn to, sealing is played under the motion operating modes such as anxious acceleration and deceleration, the effect of sound insulation, prevent the noise sent out in cabin from passing in operator's compartment, the traveling comfort that impact is driven simultaneously.This product structure is complicated, and technical requirement is higher, and in packing seal assembly in the past, bearing is mostly steel formula, weight and cost higher, and packing seal assembly soundproof effect is bad, and lining is more easy to wear.
The packing seal assembly that steering shaft conventional at present and front panel are installed is that packing seal and packing seal supporting seat form, and wherein gasket material is rubber, and inside is steel bearings, end face band annular groove.This kind of sealing arrangement is by coordinating between body dash board with steering shaft packing seal, makes rubber compressive deformation to produce thrust, thus packing seal is pressed on body dash board.
Existing packing seal assembly neck bearing is steel design, and weight is large, and cost is high, and soundproof effect haves much room for improvement.There is no anti-wearing liner in existing packing seal assembly, easily make to produce wearing and tearing between packing seal and steering shaft, reduce service life.
Summary of the invention
In order to alleviate the weight of packing seal assembly, reducing costs, improving resistance to abrasion and the soundproof effect of packing seal assembly, the invention provides the packing seal assembly that a kind of steering axles of modified node method and front panel are installed.
The present invention is achieved by the following technical solutions:
A kind of steering shaft packing seal assembly, includes packing seal, packing seal supporting seat, bearing, cavernous body and lining; Described packing seal is circular, is provided with outer outwardly, outer is provided with mounting hole on packing seal top, and the via hole junction on packing seal and body dash board is provided with the sealed groove of annular, and sealed groove fits in the inner side of body dash board; Packing seal supporting seat is installed on packing seal and is positioned at the outside that body front wall intralamellar part divides; Bearing, cavernous body and lining are all positioned at the inside of packing seal circular ring structure, are followed successively by bearing, cavernous body and lining from bottom to up.
Match with the inner shape of vehicle body in packing seal top.
Described packing seal, cavernous body and lining and bearing interference fit.
The material of described packing seal is rubber.
The material of described bearing is plastics.
Described lining is anti-wearing liner.
Described cavernous body is sound-isolating sponge body.
The invention has the beneficial effects as follows:
Plastic bearing is lightweight, and cost is low, and the soundproof effect of sound-isolating sponge body is better, has grease inside anti-wearing liner, plays lubrication, reduces wearing and tearing, dust protection effect.
Accompanying drawing explanation
Fig. 1 is using state figure of the present invention;
Fig. 2 is the A-A cut-away view of Fig. 1.
Detailed description of the invention
Describe technical scheme of the present invention in detail below by way of specific embodiment, should be understood that, following embodiment is only exemplary, only can be used for explaining and technical scheme of the present invention being described, and can not be interpreted as being the restriction to technical solution of the present invention.
As depicted in figs. 1 and 2, a kind of steering shaft packing seal assembly, includes packing seal 1, packing seal supporting seat 4, bearing 5, cavernous body 6 and lining 7; Packing seal 1 is circular rubber pad, outer is outwardly provided with on packing seal 1 top, match with the inner shape of vehicle body in packing seal top, also match with vehicle body inner shape in the outer of packing seal simultaneously, outer is provided with mounting hole 1.1, packing seal 1 is provided with the sealed groove 1.2 of annular with the via hole junction on body dash board, and sealed groove 1.2 fits in the inner side of body dash board, is beneficial to the sealing inside packing seal 1 and vehicle body; Packing seal supporting seat 4 is installed on packing seal and is positioned at the outside that body front wall intralamellar part divides, and sealing supporting seat is also provided with the mounting hole that same packing seal matches; Bearing 5, cavernous body 6 and lining 7 are all positioned at the inside of packing seal circular ring structure, are followed successively by bearing, cavernous body and lining from bottom to up, packing seal, cavernous body and lining and bearing interference fit.The material of bearing is plastics, and lining is anti-wearing liner, and cavernous body is sound-isolating sponge body.
Embodiment is, through the steering shaft 2 of vehicle body via hole, and is installed on the packing seal 1 of vehicle body via hole, and the material of packing seal 1 is rubber.Packing seal 1 and body dash board via hole junction are provided with sealed groove 1.2, packing seal supporting seat 4 is installed on packing seal 1, keep packing seal supporting seat, with body dash board, the outer portion on packing seal is sandwiched in centre, be sealed and matched by the thrust of bolt and body dash board.The mounting hole hold-down bolt of packing seal and body dash board.Steering shaft and packing seal assembly interference fit, steering shaft sealed shield 3 in packing seal lower seal, for ensureing bearing felt.
Plastic bearing 5 in section-drawing 2, plastic bearing is lightweight, and cost is low, sound-isolating sponge body 6, and soundproof effect is better, anti-wearing liner 7, and there is grease the inside, plays lubrication, reduces wearing and tearing, dust protection effect.
Although illustrate and describe embodiments of the invention, for the ordinary skill in the art, be appreciated that and can carry out multiple change, amendment, replacement and modification to these embodiments without departing from the principles and spirit of the present invention, scope of the present invention is by claims and equivalency thereof.
