Abstract

The present invention relates to a fixed clamp disk type brake for vehicles, of which the wheels are respectively fixed on a wheel hub by all wheel bolts, wherein a braking disk capable of axially moving is supported in a zone of the wheel hub and can be clamped between every two braking blocks. According to the present invention, the braking disk can be guided correspondingly to the wheel hub in an axial moving mode by at least one bolt extending part which points to the inner part, particularly a bolt extending part of each of the wheels. The abrasion of the braking disk is simply and reliably compensated with low cost in the mode.

Description

Disc brake with fixed caliper
Technical field
The present invention relates to a kind of disk type braker that is used for vehicle, especially commerial vehicle, its each wheel is fixed on the wheel hub by means of each wheel bolt respectively, have the brake disc that a moved axially ground that is provided with in the zone of wheel hub supports, its can be for example by hydraulic clamp between each brake slipper.
Background technique
In disc brake with fixed caliper, because the cumulative liner and the wearing and tearing of dish, brake disc must be able to support with moving axially, is different from the floating brake calipers disk type braker with fixing brake disc, and the there brake calipers is movably.The hydraulically operated disc brake with fixed caliper is known at sedan car and motorcycle field.Wherein brake disc directly is bearing on the hub body movably by expensive inserted tooth.For the disc brake with fixed caliper of commerial vehicle, such supporting is impossible beyond doubt, because inserted tooth is directly to be provided with by wheel bearing.This causes such consequence, and promptly especially the sealing of the wheel bearing of oiling agent and brake side is subjected to too high thermal force.Therefore the such brake disc and the direct inserted tooth of hub body require the very big ventilation flue of surcharge, are for example proposed in EP 0621829B1 as it.
Be connected on the wheel hub with flange regularly by the wheel bolt radial directed by the known brake disc of DE 29715478U in itself.
Summary of the invention
The objective of the invention is, improve the disc brake with fixed caliper of the described pattern of beginning, make it move axially reliably and do not take place with respect to wheel hub by prior art thermal force problem known, oiling agent and wheel bearing sealing.
For this reason, the present invention proposes a kind of vehicle that is used for, especially the disc brake with fixed caliper of commerial vehicle, its each wheel is fixed on the wheel hub by means of each wheel bolt respectively, brake disc with moved axially a ground supporting that is provided with in the zone of wheel hub, described brake disc can be clamped between each brake slipper in order to brake, wherein, brake disc is furnished with the hole, brake disc can guide with respect to wheel hub on the bolt extending portion of the sensing inside wheel of wheel bolt by described hole with moving axially, it is characterized in that, each hole of being used to hold the bolt extending portion is arranged on one and is different from remaining disc material, be configured in the member of guide ring, it has a center hole, and wheel hub spacing is arranged stretches in the described center hole together with wheel bearing.
According to the present invention, in the disc brake with fixed caliper of the described pattern of beginning, brake disc points to inner bolt extending portion, especially wheel bolt extending portion itself by at least one and can guide with respect to wheel hub in operation with moving axially.
When this extending portion is wheel bolt itself, can save additional bolt.Particularly avoided than expensive brake disc and the inserted tooth between wheel hub.The thermal force of wheel bearing is avoided like this, and promptly brake disc can be with enough spacings around wheel hub and not being located immediately on the wheel hub.
In the development structure of the present invention's conception, the bolt extending portion is contained in the hole of brake disc with small gap.In such a way can not interrupted (Aufschirmeffekt) by the radial expansion of the brake disc of higher brake temperature decision.
The present invention further proposes, and at least one hole that is used for holding at least one bolt extending portion is arranged on a member that is configured to guide ring that is different from remaining disc material.Its advantage is, adopts such material behavior respectively for disc material and guide ring material, i.e. its function that is particularly suitable for seeking and be worth laying siege to.When the acting in conjunction of disc material and brake slipper should reach good especially braking effect, the material of guide ring should be suitable for the lasting axial lead of brake disc on the bolt extending portion.
In addition, preferably, guide ring is by a kind of good thermoinsulation material, and for example pottery is made, so that also stop by this way from the transmission of heat of brake disc to the wheel bearing aspect.
On manufacturing technology, can make guide ring be surrounded casting simply by remaining disc material.
Not rotate in order making between guide ring and remaining disc material, can be provided with therein particularly by means of the inserted tooth that on foundry engieering, can simply make.
In the further structural design of conception of the present invention, a plurality of, preferred whole wheel bolt is equipped with a wheel bolt extending portion, and it is equably along the circle distribution of wheel hub, so that guarantee the moving axially of satisfaction of brake disc.
The bolt extending portion considers that thermal force preferably has high-intensity bolt characteristic.
Description of drawings
Other purpose, feature, advantage and application possibility of the present invention learnt by the following description by means of the embodiment of accompanying drawing.Wherein all describe and/or illustrated feature constitutes in itself or in any combination of content of the present invention.
Fig. 1 illustrates with sketch has the sectional drawing of disc brake with fixed caliper of the present invention in the part area of a wheel circumference;
Fig. 2 A is the side view according to the brake disc of the broken section of pattern of the present invention; And
Fig. 2 B is the end view according to the brake disc of Fig. 2 A, and its hatching line A-A by Fig. 2 A analyses and observe partly.
Embodiment
Disc brake with fixed caliper according to Fig. 1 is in particular the commerial vehicle appointment, and its each wheel 2 is fixed on the wheel hub 4 by means of each wheel bolt 3 and wheel nut 12.
But in Fig. 1, can find out, there is not to adopt wheel bolt 3 commonly used, but wheel bolt has such cylindrical bolt extending portion 7, its there at a convex shoulder 13 is fixed to wheel 2 on the wheel hub 4 by means of this convex shoulder with by means of wheel nut 12, and this bolt extending portion 7 stretches in the hole 8 of brake disc 5.Bolt extending portion 7 has small gap in hole 8, this gap allows brake disc 5 with respect to wheel hub 4 certain thermal expansion to be arranged on the one hand under brake temperature, guarantee the reliable axial lead of brake disc 5 on the other hand, this is necessary, because disc material 9 is worn during vehicle driving more and more.
Each brake slipper 6 acts on the disc material 9 of outside, does not illustrate in greater detail for example fluid-pressure transmission device of brake slipper 6.This conveying means is provided with in this wise, makes in the operating process of break brake disc 5 to be clamped between each brake slipper 6, so that reach either large or small braking effect.
As learning by Fig. 1,2A and 2B, brake disc 5 has a central circular hole 14, wherein can insert the inner of the wheel hub 4 that comprises wheel bearing 15 with enough spacings, thereby even brake disc 5 bears the excessive thermal force that the wheel bearing zone can not appear in higher temperature yet when braking.The oiling agent and the wheel bearing sealing that exist in the wheel bearing have particularly been protected by this way.
Particularly can find out by Fig. 2 A and 2B, brake disc 5 have in abutting connection with the hole 14 at its center one near the guide ring 10 of the different member of conduct, be positioned at wherein hole 8 as wheel bolt 3 ground evenly along the circle distribution of wheel hub 4.Disc material 9 in guide ring 10 top pourings outside.For this two member is not linked rotationally mutually, guide ring 10 embeds in the disc material 9 with inserted tooth 11, and this is undoubtedly possible in the manufacture that is proposed.
