Definitions
- the invention relates to an engine brake device for an internal combustion engine having at least one exhaust cam valve per cylinder operable by an exhaust camshaft, the engine brake device acting on the exhaust valve via a brake cam of a brake camshaft and a valve lever preferably designed as a rocker arm.
- DE 101 16 143 Al describes an engine brake, in which the exhaust valves are additionally opened in the compression stroke to achieve a braking power in the engine.
- This opening is achieved by a brake camshaft with a brake cam.
- Upon rotation of the brake camshaft press their brake cam on a free end of a cylinder head mounted in the rocker arm.
- the opening of the exhaust valves and thus the braking power can be controlled by the angle of rotation of the brake camshaft.
- the normal outlet is accomplished via a conventional camshaft and the exhaust cams located on it.
- the disadvantage is that between the brake cam and the valve lever when activated line contact occurs, which leads to considerable wear.
- an internal combustion engine with an engine brake device arranged with at least one in addition to the gas exchange valves in the cylinder head, designed as a lift valve engine brake valve known, which is actuated during engine braking via a brake valve lever against the force of a closing spring.
- the operation of the engine brake valve is effected by rotating or shifting a brake cam connected to the engine brake valve.
- DE 28 32 542 Al discloses an internal combustion engine with engine brake, which achieves the braking by opening one of the gas exchange valves by a hydraulic plunger is provided in the valve drive, in which at least one piston is guided longitudinally movably between a lower and an upper stop.
- the piston is hydraulically activated for braking and kept in normal operation of the engine by the force of a spring resiliently in a rest position.
- Similar engine braking devices are disclosed in US 4,796,573 A and EP 0 593 908 A1. A brake cam different from the exhaust cam for activating the engine brake is not provided.
- the object of the invention is to propose an engine brake device with the least possible effort and low wear. According to the invention, this is achieved by arranging a piston guided in a cylinder between the brake cam and the valve lever, wherein a surface contact preferably takes place between the brake cam and the piston at least in the engine braking mode.
- the brake cam may have a raised portion with a first cam radius on and a base portion with a second cam radius, wherein preferably the second cam radius is greater than the first cam radius.
- the second cam radius may be twice as large as the first cam radius.
- the piston has a concavely curved, preferably at least partially cylindrical, contact surface with the brake cam.
- the contact surface may further comprise a central first concave portion having a first radius of curvature which substantially corresponds to the first cam radius. It is particularly advantageous if the contact surface has at least one adjoining the first concave area second concave area with a second radius of curvature, wherein the second radius of curvature is greater than the first radius of curvature, and preferably wherein the second radius of curvature substantially corresponding to the second cam radius. In this way it can be ensured that both activated and deactivated ' engine braking device line contact between the cam and the piston is avoided.
- the brake cam and / or the piston should be made of hardened case steel or bearing steel.
- the brake cam and the cylinder are arranged in the bearing block of the rocker arm.
- valve lever acts on the outlet lift valve via a valve coupling piece, wherein the valve coupling piece is mounted so as to be axially displaceable in a valve actuating part, preferably in a valve bridge. This prevents the valve actuating part from possibly opening a second outlet valve when the engine braking device is activated.
- the rotation of the camshaft can be done by an electric servomotor, purely mechanical or mechanical-hydraulic.
- the brake cam is hydraulically adjustable, wherein preferably a hydraulically adjustable rack engages in a fixedly connected to the brake cam gear.
- the brake cam can also be adjusted via a lever by a control linkage.
- FIG. 1 shows an engine brake device for an internal combustion engine according to the invention in section in an oblique view.
- FIG. 2 shows the engine brake device in an oblique view in a first embodiment
- FIG. 4 shows the detail IV of FIG. 1 of the deactivated engine brake device
- FIGS. 1 to 3 each show an engine brake device 1 for an internal combustion engine, with the engine brake device 1 acting on an exhaust lift valve 2 opening into a combustion chamber (not shown).
- the engine brake device 1 has a brake camshaft 3 with a brake cam 4, which is rotatably mounted in a bearing block 5.
- the brake cam 4 acts via a displaceably mounted in a guide cylinder 6 of the bearing block 5 piston 7 on a rocker lever designed as a lever 8, which acts on a valve decoupling piece 9 on the shaft 2a of the exhaust valve 2.
- the valve decoupling piece 9 is axially displaceably mounted in a valve actuating part, for example in a valve bridge 10.
- valve bridge 10 engages - directly or indirectly - a not shown exhaust camshaft for actuating two Auslasshubventile, of which only the Auslasshubventil 2 is shown.
- the axis of the valve lever 8 is denoted by 8a.
- the bearing block 5 is attached via one or more screws 11 to a cylinder head upper deck, not shown.
- an adjusting screw 12 is provided on the lever 8.
- the piston 7 moves by a predefined distance of, for example, 2 mm in the direction of the valve lever 8 and allows its tilting, whereby the outlet lift valve 2 is opened.
- the rotation of the brake camshaft 3 can be achieved via an actuating lever 13. follow, as shown in Fig. 2, or via a rack 14 (see Fig. 3).
- the actuating lever 13 may be connected in a known manner via a control linkage with a pneumatic or hydraulic actuator.
- the brake camshaft 4 a gear 15, in which engages the rack 14.
- the designed as a pressure piston rack 14 is hydraulically pressurized in braking operation and rotates the camshaft on the gear 15 by an angle of about 90 ° over the teeth.
- the rack 14 is relieved hydraulically, whereby this is pushed back by means of the spring 16 in the starting position.
- FIG. 4 shows a detail of the engine brake device during normal operation, that is to say deactivated engine brake device 1, and FIG. 5 shows this detail during engine brake operation. It can be seen clearly that a wear-intensive line contact between the brake cam 4 and the piston 7 is avoided both in normal operation, as well as in engine braking operation. It is essential that the piston 7 has a concave contact surface 17 which conforms to the brake cam 4, in particular during engine braking operation, but advantageously also during normal operation.
- the brake cam 4 in this case has a raised portion 4a with a first cam radius T 1 and a base portion 4b with a second cam radius r 2 .
- the second cam radius r 2 is designed to be larger than the first cam radius ri, wherein the second cam radius r 2 is approximately twice as large as the first cam radius ri.
- the contact surface 17 of the piston 7 has a central concave first region 17a, the radius of curvature Ri of the first region 17a substantially corresponding to the first cam radius ri. Furthermore, the contact surface 17 has two concave second regions 17b adjoining the first region 17a, the radius of curvature R 2 of each second region 17b substantially corresponding to the second cam radius r 2 .
- the contact partners cam 4 and piston 7 should be made at least of hardened case steel or bearing steel.
