Abstract

The steering axle configuration for drive wheel of car has a bearing part, which is fixed to suspension unit and supports a slide block, a braking disc and a wheel bearing. Wheel shaft has synchronous movable joint and flange for fixing braking disk to reduce the number of parts, weight and installation fee. Said bearing part, flange, wheel shaft, braking disc and bowl part of synchronous movable joint constitute an assembly for finally fixing to wheel Macpherson strut unit.

Description

The steering axles configuration

The present invention relates to the steering shaft configuration of notional automobile driving wheel described in the claim 1.

The steering shaft of this configuration for example just can be learnt in German patent DE3044185A1.This known steering shaft configuration is made up of more a plurality of parts, and interconnecting of this part will be spent very high erection cost.Simultaneously, also need other add-on partss as the connection means.Like this, not only improve manufacturing cost, and increased the weight of the weight of steering shaft.

In addition, general people make every effort to reduce the final installation usefulness that is used for automobile as far as possible.If after the support unit of steering spindle arrangement being fixed on the wheel suspension system of automobile, must install and be used for gear-driven Die Scheibenbremse or gear-driven synchronous movable joint, should think that then this is a shortcoming.

Task of the present invention is: consider in light weight and the installation simple question, should improve the configuration of this steering shaft, simultaneously, should fall the final erected cost of automobile especially.

The terms of settlement Accessory Right of this task requires to learn in the part indicated in 1, and the major part of steering shaft configuration of the present invention is to be combined into an assembly, this assembly be pre-assembled and also by supply plant it is integrally offered the vehicle manufacturer.When the final installation of automobile, the black box that is pre-assembled is fixed on only seldom operation on the automobile suspension arrangement.

Structure with these advantages forms, and particularly he has reduced the various parts of steering spindle arrangement of the present invention, has also reduced its weight, and details are the explanation in the claim as follows.

In the described version of claim 2, the cantilever of slide block--Die Scheibenbremse is done as a whole concentrating and is contained in the support unit of steering spindle arrangement.Like this, reduce assembling of cantilever and support unit and fix screw and carried out fastening expense.If can move on cantilever by claim 3 slide block, all functions of the beam that then brakes all concentrate on the support unit.

In the described version of claim 4, the warp-wise outer rim of wheel bearing is fixed by being pressed in the support unit.Do not need the fixation of adding.Also have some other good measures to see claim 5, wherein the warp-wise inner edge of wheel bearing and rotation (rotation) axle body constitute an integral body.

Other versions preferably that constitute about axle body is simple are seen

claim

6 and 7, and wherein movable section part or the flange that is used for fixing Die Scheibenbremse constitute one with wheel shaft synchronously.

Support unit version is preferably seen claim 8 to 12, and one or more connecting elements (section) are wherein arranged on support unit, or is furnished with joystick and best and integral body of support unit formation in the automotive wheels of handling.Recommendable especially is claim 12, and support unit constitutes a foundry goods, simple and price is lower.

Below by figure embodiments of the invention are elaborated: as shown in the figure:

Planar view Fig. 2 of part partly cut-away: the cutaway view at the A place, position of Fig. 1 medium casting.Fig. 3: with rotation (rotation) parts and wheel rim connect together shown in mounted steering shaft dress

Put the principal section figure of B-B line in Fig. 1.

Can find out support unit 1 among Fig. 1, a main annular center part 2 that has centre hole 3 is arranged, individual cantilever 4,5 divide 2 from central division at first along taking turns to dividing to outwards move on the outward flange that reaches the Die Scheibenbremse 8 that is shown in broken lines always, the celestial cantilever 4 of this scope, 5 bend to horn shape and they divide to being projected on the Die Scheibenbremse 8 vertically with

guide piece

6,7.

Two

brake shoes

9,10 that are contained in Die Scheibenbremse 8 both sides move axially on targeting part 6,7.Preferably as shown in Figure 3, slide block 11 is fixed on the support unit 1 by means of two bolt guide piecees 12, and can move axially equally.Slide block 11 is clamped the outer rim of Die Scheibenbremse 8 and is pincerlike two

brake shoes

9,10 that clamp.At axial inboard brake cylinder 13 a brake cylinder piston 14 is housed, when carrying out glancing impact, this brake cylinder piston directly acts on the interior brake shoe 9.If brake shoe 9 is pressed on the Die Scheibenbremse, then, be pressed on the opposite side of Die Scheibenbremse 8 in its bolt guide piece 12 until outer brake shoe 10 because antagonistic force slide block 11 moves, thrust required when having only brake shoe 9.10 to compress is transmitted by slick and frivolous piece 11.The tangential force that braking produces owing to friction is directly delivered to the targeting

part

6,7 of cantilever 4,5 by

brake shoe

9,10.

Support unit 1 is equipped with the

fastener

15,16 of two different sizes, and they extend in fact in the opposite direction from center piece 2.Fastener 15,16 each has a hole 17,18 and is used for fixing with wheel suspension system, and wherein bigger fastener hole is also bigger, only can find out in Fig. 2.In addition, support unit 1 also is equipped with a joystick 19, and this bar begins in fact to avoid the warp direction of disk brake and link to each other with automobile control lever from center piece 2.

Support unit 1 is made up of a mono-foundry goods, wherein on center piece 2 by arm 4,5,

fastener

15,16 and joystick 19 constitutes an integral body.The outer rim 20 of wheel bearing 21 is pressed in the centre hole 3 of support unit 1.The inner edge 22 of wheel bearing 21 constitutes an integral body with wheel shaft 23.The bowl-type parts 24 of so synchronous movable joint also are to constitute an integral body with wheel shaft 23 in the inboard.Thus, wheel shaft is connected with not shown transmission shaft, and carries out transmission.At last, be used for fixing the flange 25 of Die Scheibenbremse 8 and wheel rim 26 with integral body of wheel shaft 23 formations.

The above-mentioned rotatable single-piece wheel axis body that is contained in the supporting have the wheel shaft 23 of wheel bearing 21 inner edges 22 effect, a synchronous movable joint bowl 24 effect and be used for fixing the effect of flange 25 of Die Scheibenbremse 8 and the effect of wheel rim 26.Under certain conditions, saved required attaching parts and the functor of connection that is used for called function spare.

Flange 25 has the screw hole 27 that the inside can be screwed into screw 28, and wherein wheel rim 26 and Die Scheibenbremse 8 all link together tightly with flange 25.

Particularly constitute a combiner by support unit 1 and wheel shaft 23, result's steering spindle arrangement weight saving of the present invention, processing charges has also reduced, if will be equipped with according to the present invention that the support unit 1 of disk brake 11 and wheel bearing 21 constitutes an assembly with wheel shaft that comprises flange 25 and bowl 24 and Die Scheibenbremse 8 and the pre-packed integral body when finally installing as automobile is ready to stand-byly, this has just showed its special benefits.In this case, the required erection work of the assembled that is useful on can finish by supply plant, and final erection cost can reach bottom line.
