Description

(54) VEHICLE PEDAL INSTALLATION (71) We, DAIMLER-BENZ AKTIENGESELL SCHAFT, a Company organised under the laws of the Federal Republic of Germany, of Stuttgart-Unterturkheim, Federal Republic of Germany, do hereby declare the invention, for which we pray that a patent may be granted to us, and the method by which it is to be performed, to be particularly described in and by the following statement:- The invention relates to a vehicle pedal installation for the brakes, and/or for the clutch, of a motor vehicle, having a front wall between the engine compartment and passenger compartment the installation including a subassembly of a vacuum chamber and master cylinder which is supported by the front wall of the motor vehicle.
Hitherto, the brake pedal and clutch pedal when one was present in a motor vehicle not provided with automatic transmission, have been mounted on a common base to constitute a pedal assembly. The latter was screwed, during assembly, from the passenger compartment against a surface provided for it on the front wall, whilst at the same time the vacuum chamber-brake master cylinder subassembly was inserted from the engine compartment side and was then connected detachably to the pedal assembly by screws. This operation was very tedious and complicated.
It necessitated two workers who introduce and feed the two subassemblies in from both sides of the front wall, pay great care and attention to ensuring the coincidence of the screw holes, and had to screw the nuts to bolts from both sides.
The object of this invention is to simplify and facilitate this assembly operation which necessitates two workers and takes quite a long time, whilst the aperture necessary for passage in the front wall should be closed and sealed simultaneously and unobtrusively in a neat manner without additional outlay. It is a further aim of the invention to create a stable base for supporting the subassembly.
According to the present invention there is provided a vehicle pedal installation, the vehicle having a front wall between the engine compartment and the passenger compartment, wherein a pedal assembly having at least one pedal is connected to a vacuum chamber and to a master cylinder to form a subassembly, the subassembly having a housing which, by an end wall thereof closes fluid-tightly an aperture in the front wall which lies approximately horizontally, through which aperture a pedal or pedals project into the passenger compartment the subassembly being secured to said front wall.
By a different formation of the front wall with a horizontal orientation of the same in the region of the aperture provided by the pedals and by an adaptation of the front wall slope to the pedal assembly or conversely an adaptation of the external dimensions of the pedal assembly to the modified front wall and by the combination of the two subassemblies vacuum chamber with brake master cylinder and pedal assembly to form a single assembly unit it is possible for one worker to insert said assembly unit easily into the vehicle as a fully preassembled component in its totality and to screw it in the prescribed place. The pedal housing chosen and the front wall in the region of the aperture for the pedals are so constructed that the housing divides the interior passenger space of the motor vehicle from the engine compartment. At the same time, the housing may embrace all the elements belonging to the pedal unit. It is also possible to include the vacuum chamber nondetachably in the housing. This can be effected by screwing the pedal assembly together with the vacuum chamber. But the vacuum tank may also be welded to the pedal assembly, or if both parts are produced of sheet metal, they may also be joined together to form an assembly unit by beading or folding.
The housing for the pedal assembly may also be extended above the vacuum chamber, so that the housing for the pedal assembly also embraces and contains the vacuum chamber.
The orientation of the front wall in the region of the pedal assembly may be adapted to the external dimension of the pedal assembly on at least two sides of the same. But it may also be reversed in that the external dimensions of the pedal assembly are adapted to the required conditions of the front wall.
It may also be advantageous if the housing for the pedal assembly carries a bearing for a regulating shaft for the vehicle accelerator pedal.
An embodiment of the invention will now be described by way of example with reference to the accompanying drawing, which shows a pedal assembly according to the invention installed in the engine compartment of a motor vehicle, viewed in a longitudinal section through the engine compartment housing. The subassembly is constituted by a brake master cylinder 1, a vacuum chamber 2 and a pedal assembly 3. These three components are combined to form an integral assembly unit.
A front wall 4 divides engine compartment 5 from the passenger compartment 6 of the vehicle.
In known types of vehicle structure, the front wall extended in the region of the dividing line 7 between the vacuum chamber 2 and the pedal assembly 3. Accordingly the subassembly comprising master cylinder 1 and vacuum chamber 2 was introduced from the engine compartment 5, whereas the pedal assembly 3 was brought up from the passenger compartment side and the two had to be screwed together on the front wall in the region of an aperture provided therein. This required two workers each of which fed a subassembly from the one or the other side and brought the screw holes into coincidence, which is a time-consuming job. Then screws were inserted through the screw holes from one side and bolted tight from the other side, for which purpose again two workers were necessary.
Now according to the manner of the invention, the front wall 4 is constructed so that it extends approximately horizontally in a region round an aperture 8. In this region the integral assembly unit is placed by being introduced from above into the engine compartment 5. In order to install this assembly unit the engine compartment cover 9 which is located above the engine compartment 5 is opened so that the assembly unit comprising brake master cylinder 1, vacuum chamber 2 and pedal assembly 3, can be introduced with the pedals 12 leading so that the pedals 12 can first be inserted through the aperture 8, until the pedal assembly 3 together with the master cylinder and the vacuum chamber 1 and 2 then occupies the position illustrated in the drawing.
The orientation of the front wall 4 in the region of the pedal assembly 3 on both sides 13 and 14 is so constructed that it is adapted to the external dimensions and slope of the pedal assembly at this point so as to fluidtightly close the aperture 8. The windscreen 15 then adjoins above the section 14 of the front wall 4.
Above the pedal assembly 3 there is fitted to its housing a bearing 16 for an accelerator regulating shaft which, when actuated by the accelerator pedal, regulates the acceleration of the vehicle.
It is also possible to include the vacuum chamber 2 in the housing of the pedal assembly 3 and to produce said housing in one piece so that it surrounds the vacuum chamber and the pedal assembly. Although described with reference to a brake pedal it will be understood that the invention is not only equally applicable to a clutch pedal assembly but also to the combination of brake and clutch pedal assemblies.
