Disc brake for vehicles having insertable actuator
A brake disk for road vehicles has a brake caliper engaging about a brake disk of a vehicle wheel to be braked. A clamping unit upon which an actuation cylinder can act is provided on one side of the brake disk and which itself acts against at least one pressure member. In order to withstand the braking forces in a manner free from sealing problems, the caliper is constructed in one part such that the clamping unit is mounted in a section of the caliper which is substantially closed on all sides. When the caliper is moved away from the brake disk, the clamping unit can be introduced, in the form of a preassembled unit into the caliper through the opening therein facing the brake disk. When the clamping unit has been introduced, the opening in the brake caliper facing the brake disk is closed by a closure plate penetrated by the pressure member of the clamping unit.
The invention relates to a disk brake for road vehicles, having a caliper and which comprises a brake disk with a brake application unit arranged on one side, the application unit having a rotary lever swivellable by an operating cylinder, the rotary lever being capable of acting by means of an eccentric onto a bridge which can be displaced against a spring force in the direction of the brake disk has at least one adjusting spindle provided with a pressure scheme.
In the case of disk brakes of the above-mentioned type (German Patent Document DE-OS 40 32 886), a brake application device, which is equipped with a rotary lever which can be acted upon by an operating cylinder, isprovided inside the rearward part of a caliper comprising a brake disk, which application device has a bridge which carries two adjusting spindles having pressure pieces and is slidably supported on the caliper. The end of the rotary lever which eccentrically acts upon the portion of the bridge facing away from the brake disk is supported on the rearward end of the caliper by means of slide bearing or roller bearing elements. The rearward section of the caliper is constructed as a separate housing which can be screwed together with the caliper along a separating line. During the operation of the brake, the brake response forces are introducedin a rearward manner into the screwed-on housing section which can cause problems concerning the screwed connection, the stability and the sealing, particularly during the service lives required in the case of disk brakes of the concerned type. Problems of the above-mentioned type may also occur in the case of disk brakes which are constructed with only one adjusting or pressure spindle.
Based on the above, it is the object of the invention to further develop a disk brake of the above-mentioned type such that the brake response forces can be introduced into the brake caliper without any problems. In particular, sealing areas existing at the caliper must be completely unaffected by the braking or brake response forces in order to ensure the required operational reliability during long service lives of the brake system.
This object is achieved according to preferred embodiments of the present by providing a disk brake of the above mentioned type, wherein
a) the caliper is constructed in one piece such that the section of the caliper receiving the application unit is largely closed in a rearward area facing away from the brake disk, with the exception of an opening for the access of the operating cylinder, and
b) the application unit can be inserted as a preassembled unit into the caliper through the opening facing the brake disk when the caliper is removed from the brake disk.
Because of the one-piece design of the caliper, which in a cost-saving manner may be constructed as a cast part, a direct transmission of the braking forces into the caliper is permitted since the rearward area, which faces away from the brake disk, of the caliper receiving the application unit is essentially closed with the exception of the through-grip opening for the operating cylinder. The application unit, including all its components, can be introduced as a preassembled unit when the caliper is removed from the brake disk through the opening facing the brake disk. After the introduction of the application unit, this opening of the caliper can preferably be closed by a closing plate which, in the case of a two-spindle brake disk construction, is penetrated in a sealing manner by the pressure pieces on the forward ends of the adjusting spindles. The application unit can be constructed as a preassembled unit by means of simple holding or clamping elements. Its position inside the section of the caliper acting as the housing is determined by the supporting roller which is supported on the interior side on the rearward wall section of the caliper and, facing the brake disk, is determined by the pressure spring which tensions the application unit in a rearward manner and is supported on the closing plate.
Other objects, advantages and novel features of the present invention will become apparent from the following detailed description of the invention when considered in conjunction with the accompanying drawings.
FIG. 2 and is an individual sectional view of the preassembled application unit;
According to the invention, the caliper 1 is constructed in one piece; that is, the section which is situated on the rightin the drawing of FIG. 1 and receives an application unit 13 and the section comprising the brake disk 3 are constructed in one piece as a cast part or forged part. The application unit 13 has a rotary lever 15 which, in the view according to
For the lateral support of the bridge 29, sliding elements 39 are provided which, when the brake is operated, absorb circumferential forces arriving by way of the pressure pieces and divert them to the caliper. The sliding elements 39 may consist of steel and have the shape of cylindrical bodies. However, sliding elements of a different configuration may also be used.
According to
In the interior of the adjusting spindle 33 illustrated on the left side in
The operating device described above is illustrated in
The bow spring 61 is only an embodiment of a device by means of which the individual components of the application device, including the closing plate 41 and the pressure pieces 35, 37 are held together as a unit in a manner illustrated in FIG. 2. When the caliper is removed from the brake disk, the preassembled unit illustrated in
After the rearward end of the caliper has largely been closed, laterally accessible devices are provided which permit an access to the synchronizing device. According to
The invention is not limited to the illustrated application device with the use of two adjusting spindles and also not to the special shaping of the bow spring 61 which holds together the preassembled unit. Instead of the two-spindle construction of the pneumatically applicable disk brake shown as an example, a single-spindle disk brake construction can be provided which is therefore equipped with only one adjusting spindle and one pressure piece. This means that the principle of the use of a one-piece caliper and of the application device which can be introduced as a preassembled unit into such a caliper can also be used in the case of constructions of those types known per se in which a central adjusting and pressure spindle can act upon a brake lining by means of a single pressure piece. Therefore, independently of the type of the application device, within the scope of the idea of the invention, the advantage can be achieved that the braking forces are transmitted by way of the supporting roller directly into the caliper; that is, in the case of tension and bending stress, no force transmission takes place by way of screwed-on housing parts which are subjected to leakage problems.
Although the invention has been described and illustrated in detail, it is to be clearly understood that same is by way of illustration and example, and is not to be taken by way of limitation. The spirit and scope of the present invention are to be limited only by the terms of the appended claims.
