Definitions

• the invention relates to an arrangement of a front-side drive unit comprising an engine and a transmission in a motor vehicle, in which the body floor is formed with a tunnel-like central longitudinal beam, in which the end of the drive unit facing the passenger compartment projects and the drive unit has a bearing there. and has support device.
• a drive unit which consists of an internal combustion engine with a flange-mounted gear
• the internal combustion engine is mounted on both sides.
• the flanged gearbox projects into a central tunnel and is supported once in its central area so that a three-point bearing is formed for the drive unit.
• the base of the bearing points should be as large as possible, which can still be improved here.
• both the steering wheel and the seat belt mechanism 1b are connected with ropes which are connected to the drive unit or a "cable catcher" on the drive unit via a deflection device. If the drive unit is moved rearward to the passenger compartment in the event of a strong front impact, the steering wheel is pulled away from the possible head impact area in the direction of the dashboard and the seat belts are pretensioned at the same time. In order to obtain a suitable arrangement for the cable deflection, the cable catcher is located relatively far from the transmission on the passenger compartment. Given the large number of vehicle types with the option of choosing
• the object of the invention is an arrangement
• the bearing and support device du forms a support tube protruding into the central longitudinal member in the longitudinal direction of the vehicle as an extension of the drive unit. Since in conventional vehicle designs with an A drive unit consisting of an internal combustion engine and a flanged-on transmission, the transmission usually points in the direction of the passenger compartment, the carrier tube is usually designed as an extension of the transmission housing. In another known drive unit arrangement, the internal combustion engine and the transmission are divided and separated in each case in a front and rear area of the vehicle and connected via a central tube. This central tube can also be used as a support tube according to the invention.
• the carrier tube can in principle have all possible cross sections and can also be formed from Vo material for various applications.
• a round or square cross section of a hollow tube with the advantages of high energy absorption by so-called folding bulges of inexpensive manufacture and processing and a desired low weight is preferably used.
• connection between the drive unit or gear housing and the support tube must be fixed due to the bearing and support function of the support tube. According to claim 3, it is therefore proposed to either cast on the support tube directly o to insert and / or screw on the drive unit.
• the support tube results in connection with the above-mentioned safety device for pulling the steering wheel away and for pretensioning the seat belts.
• the cable catcher is attached to the support tube so that it can be moved and locked securely.
• the attitude to tightening the ropes becomes l by moving the cable catcher on the support tube and then locking, the length of the support tube serving as the adjustment length.
• the support tube is located in a torque bearing arranged in the central longitudinal support.
• the drive unit is supported with the desired large base of the bearing points.
• the arrangement according to claim 6 is particularly favorable if the support tube is supported far back at its free end in the torque bearing. This results in quiet storage
• Claim 7 proposes to design the carrier tube in such a way that when it is subjected to a force, its longitudinal
• a support or abutment is provided in the central longitudinal beam in the area of the free end of the support tube, which is of a very solid design and on which the end face of the support tube rests when the front face is strong.
• the carrier tube is shortened by folding and absorbs a certain proportion of the impact energy. On the one hand, this leads to an advantageous increase in overall energy consumption and, on the other hand, to the fact that the
• FIG. Shows an arrangement of a drive unit on the front with an extension through a support tube, on which a cable catcher is adjustably fastened and which is used for mounting the drive unit.
• 5 shows the arrangement of a drive unit 1 on the front side in a motor vehicle, in which the body floor is provided with a central longitudinal beam 2 designed in the manner of a tunnel.
• the drive unit 1 consists of a motor 3 and a flange-mounted thereon
• Transmission 4 The transmission 4 or its housing is extended in the vehicle longitudinal direction by a carrier tube 5. Both the end of the drive unit facing the passenger compartment and the extension through the carrier tube 5 protrude into the central longitudinal member 2.
• the drive unit 1 comprising the motor 3 and the transmission 4 is mounted on the body by two motor bearings 6 which are each laterally attached to the motor 3 and by a torque bearing 7 in the central longitudinal member 2.
• the motor mounts 6 and the torque mounts 7 essentially contain rubber-metal elements with possibly liquid-filled damper chambers for elastic support.
• the base for the mounting of the drive unit 1 is through the support tube 5 towards the rear the third bearing point displacing the passenger compartment is large in the desired manner. An acoustically favorable mounting of the drive unit 1 can thus be carried out with low unit movements and high comfort.
• a support bearing 8 in the form of a metal plate filling the central longitudinal beam 2 is arranged in the central longitudinal beam 2 after the moment bearing 7.
• the carrier tube 5 is round or square in cross-section and specifically designed for deformation by folding when a force applied in the axial direction acts on the carrier tube 5.
• the formation for a targeted deformation by folding is indicated schematically by notches 9.
• the cable catcher 14 is moved in the direction of the passenger compartment and the deflection part 13 is also held on the body.
• Another rope 18 is connected to seat belts (not shown). This rope 18 is also connected to the seat belt
• the cable catcher 14 is slidably arranged along the support tube 5
