Definitions
- the invention relates to a friction wheel drive for frictionally driving an auxiliary unit of an internal combustion engine, with an adjustable friction wheel, which can be pressed against at least one contact disk of an output member and / or a drive member.
- friction wheel drive with an adjustable friction wheel that can be pressed onto the contact disk of a drive element and that has its own drive.
- the friction wheel drive comprises an electric motor, which drives a friction wheel via a gear, which can be adjusted in the direction of a wheel rim as required.
- the wheels which are electrically driven via the friction wheel drive, support the conventionally driven wheels in the event of insufficient static friction, which can occur for example with black ice or in the case of poor performance of the conventional drive z. B. on too steep slopes.
- a disadvantage of the friction wheel drive described above is that due to its independent drive, a large number of additional components are required, which increase the susceptibility to faults as well as the required installation space and the weight of the system.
- the invention has for its object to provide a friction wheel drive for an auxiliary unit of an internal combustion engine, wherein the friction wheel drive with low construction costs meets the contact pressure of the friction wheel required for the frictional transmission of the drive torque with acceptable tolerances.
- an advantage for an exact design and function of the wedge ring groove, which is adjustable in width, is that the running disk has a circular cylindrical sleeve, on each of which a cylindrical section of the side walls is axially guided, which is firmly connected to a conical section of the same and which together form the form an adjustable wedge ring groove.
- the spring means are designed, for example, as plate springs, which are supported on end stops of the circular-cylindrical sleeve and on the conical section of the sides.
- a degressive spring characteristic of the diaphragm spring combines the advantage of a small axial space requirement due to the initially rapid increase in spring force with a slightly increasing spring force in the end region of the spring stroke. As a result, slight changes in the position of the friction ring have an insignificant effect on the contact pressure of the friction wheel.
- a presetting of the friction ring is achieved during the assembly of the friction wheel in that the eccentricity and thus the contact pressure of the Contact discs of the output and drive member adjacent friction ring is preset by moving the motor-fixed roller bearing along a tension line of the running disk.
- the exact size of the eccentricity of the friction ring arises under the prevailing boundary conditions of z.
- Conical friction rings made of steel or light metal are particularly well suited for high contact forces, since the relatively large, conical contact surfaces of the friction ring and the wedge ring groove require a relatively low surface pressure between them, which cause a correspondingly low level of wear.
- a circular or elliptical cross section of the friction ring offers advantages, especially if it is hollow and made of elastomer material. Similar to a pneumatic tire, its contact surface easily adapts to the unevenness and dimensional deviations of the friction partners without causing major fluctuations in the contact pressure.
- a particularly simple solution combined with the friction wheel drive Wegstoffantriebs is achieved in that the driven member is not formed as a traction means enclosed contact or V-belt pulley of the crankshaft but as a slack side of the traction means, the said drive, for example, a generator and an air compressor is used as a normal belt '.
- the friction wheel is also a deflection and calming roller for the empty run.
- Figure 1 is a view of a combined friction wheel and traction drive with a friction wheel according to the invention, which is in indirect pressure contact with a contact disk of an output member;
- FIG. 2 shows a view of a combined friction wheel and traction mechanism drive according to FIG. 1, in which the friction wheel according to the invention is in direct pressure contact with an empty run of the traction mechanism drive;
- Figure 3 shows a longitudinal section through the friction wheel according to the invention with a friction ring of wedge-shaped cross section
- Figure 4 is a longitudinal section as in Figure 3, but with a friction ring of oval cross-section.
- FIG. 1 shows a view of a friction wheel drive 1 which is combined with a traction drive 2.
- the friction wheel drive 1 comprises a friction wheel 3, 3 'according to the invention, which has a friction ring 4, 4' which is mounted so as to be radially movable in a wedge ring groove 24 of a running disk 5 arranged fixed to the motor.
- the structure of the friction wheel 3, 3 ' is dealt with in more detail in the description of FIGS. 3 and 4.
- the friction ring 4, 4 ' is in indirect, frictional contact with a contact or pulley 7 of an output element 8 of a crankshaft 27 enclosed by a traction means 6. conclusive connection, during which is in direct frictional contact with a contact disk 9 of a drive element 10 of an auxiliary unit 11.
- the auxiliary unit 11 is, for example, a coolant pump.
- the traction mechanism drive 2 serves to drive a generator 12 and an air conditioning compressor 13.
- the traction mechanism 6, which is designed as a normal belt, connects all associated contact disks to the contact disk 7, which is connected to the crankshaft in a rotationally fixed manner and at the same time forms the output element 8.
- FIG. 2 shows a view of an alternative friction wheel drive 1 'and an alternative traction drive 2' combined with this. These are characterized by the position of the friction wheel 3, 3 'in relation to the traction means 6.
- the friction ring 4, 4 ' also serves as a deflection and calming roller for the empty strand 15.
- FIG. 3 shows a longitudinal section through the friction wheel 3 according to the invention.
- This has a running disk 5 and a friction ring 4.
- the running disk 5 has a circular cylindrical sleeve 18 which is mounted on a roller bearing 19.
- the roller bearing 19 is fixedly connected to a motor housing, not shown, by means of a clamping screw 20.
- On the sleeve 18 there are two identical side walls 21 which are arranged in mirror image and are axially displaceable.
- the side walls 21 each consist of a cylindrical section 22 and a conical section 23 fixedly connected thereto.
- the cylindrical section 22 serves for the axial guidance of the side walls 21 on the sleeve 18, the conical sections 23 together form an adjustable in width Wedge ring groove 24 for the friction ring 4. This has a larger diameter than the wedge ring groove 24.
- the side walls 21 are acted upon by opposing, axial spring forces.
- a plate spring 25 is provided, which is supported on end stops 17 of the sleeve 18 and on the conical sections 23 of the side walls 21. They are designed with slots and have a degressive characteristic. Due to the spring forces acting on the side walls 21, the friction ring 4 is clamped between them and, due to the wedge ring-shaped, smooth flanks of the wedge ring groove 24 and the friction ring 4, experiences a radially acting force component which acts as a pressing force on the contact disks 7, 9 or on the empty strand 15 the pulling means 6 acts.
- the friction ring 4 can automatically adapt to the unevenness and dimensional deviations of the friction partners. Given the slight radial movements of the friction ring 4 in question, the fluctuations in its contact pressure are small, so that overloading of the friction wheel 3 or slippage thereof is avoided.
- Figure 4 differs from Figure 3 only by a friction ring 4 ', which has an oval or circular cross section with an annular cavity 16 and which is made of polymer material. Like a pneumatic tire, the friction ring 4 'adapts flexibly to the possible unevenness and dimensional deviations of the friction partners and thus avoids major fluctuations in the contact pressure of the friction wheel 3'.
