Abstract
The invention relates to a sealing pad assembly of a steering shaft. The sealing pad assembly comprises a sealing pad, a sealing pad supporting seat, a bearing, a sponge and a bush; the sealing pad is circular, and an annular sealing groove is formed in a joint of the sealing pad and a via hole in a front panel of a vehicle body and clings to the inner side of the front panel of the vehicle body; the sealing pad supporting seat is mounted on the outer side of a part, which is positioned in the front panel of the vehicle body, of the sealing pad; the bearing, the sponge and the bush are positioned inside a ring structure of the sealing pad and are sequentially arranged from bottom to top.
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 coaming plate junction, how reasonably to design packing seal, it is being turned to, under the motion operating modes such as anxious acceleration and deceleration, play sealing, the effect of sound insulation, prevent that simultaneously the noise of sending out in cabin from passing in operator's compartment, the traveling comfort that impact is driven.This product structure complexity, technical having relatively high expectations, in packing seal assembly in the past, bearing is mostly the steel formula, and weight and cost are higher, and packing seal assembly soundproof effect is bad, and lining is more easy to wear.
The packing seal assembly of steering shaft commonly used and the installation of front coaming plate is that packing seal and packing seal supporting seat form at present, and wherein gasket material is rubber, and inside is the steel bearing, end face band annular groove.This kind sealing arrangement is by coordinating between body dash board and steering shaft packing seal, makes the rubber compressive deformation to produce thrust, thereby 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.In existing packing seal assembly, there is no anti-wearing liner, easily make between packing seal and steering shaft to produce wearing and tearing, reduce service life.
Summary of the invention
In order to alleviate the weight of packing seal assembly, reduce costs, improve resistance to abrasion and the soundproof effect of packing seal assembly, the invention provides a kind of steering axles of structure and packing seal assembly that front coaming plate is installed of improving.
The present invention is achieved by the following technical solutions:
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, on packing seal top, is provided with on outwards outstanding ，Zai outer, outer and is provided with mounting hole, 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 inboard of body dash board; The packing seal supporting seat is installed on packing seal and is positioned at the outside that the body front wall intralamellar part divides; Bearing, cavernous body and lining all are positioned at the inside of packing seal circular ring structure, are followed successively by from bottom to up bearing, cavernous body and lining.
Match with the inboard 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 the 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, and there is grease anti-wearing liner the inside, play lubricated, reduce wearing and tearing, dust protection effect.
The accompanying drawing explanation
Fig. 1 is use constitution diagram of the present invention;
Fig. 2 is the A-A cut-away view of Fig. 1.
The specific embodiment
Below by specific embodiment, describe technical scheme of the present invention in detail, 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 to be interpreted as is the restriction to technical solution of the present invention.
As depicted in figs. 1 and 2, a kind of steering shaft packing seal assembly, include packing seal 1, packing seal supporting seat 4, bearing 5, cavernous body 6 and lining 7; Packing seal 1 is circular rubber pad, on packing seal 1 top, be provided with outwards outstanding outer, match with the inboard shape of vehicle body in packing seal top, also match with the inboard shape of vehicle body in the outer of packing seal simultaneously, on outer, be provided with mounting hole 1.1, packing seal 1 is provided with annular sealed groove 1.2 with the via hole junction on body dash board, and sealed groove 1.2 fits in the inboard of body dash board, is beneficial to the sealing of packing seal 1 and vehicle body inboard; Packing seal supporting seat 4 is installed on packing seal and is positioned at the outside that the body front wall intralamellar part divides, and on the sealing supporting seat, also is provided with the mounting hole that same packing seal matches; Bearing 5, cavernous body 6 and lining 7 all are positioned at the inside of packing seal circular ring structure, are followed successively by from bottom to up bearing, cavernous body and lining, 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 the sound-isolating sponge body.
Embodiment is, passes 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 is provided with sealed groove 1.2 with body dash board via hole junction, packing seal supporting seat 4 is installed on packing seal 1, keep in the middle of the packing seal supporting seat is sandwiched in the outer section on packing seal with body dash board, thrust and body dash board by bolt are sealed and matched.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 is in the packing seal lower seal, be used to guaranteeing bearing felt.
In section-drawing 2, plastic bearing 5, and plastic bearing is lightweight, and cost is low, sound-isolating sponge body 6, soundproof effect is better, anti-wearing liner 7, there is grease the inside, play lubricated, reduce wearing and tearing, the dust protection effect.
Although illustrated and described embodiments of the invention, for the ordinary skill in the art, be appreciated that without departing from the principles and spirit of the present invention and can carry out multiple variation, modification, replacement and modification to these embodiment, scope of the present invention is by claims and be equal to and limit.
