摘要： The present invention pertains to a cam follower for a valve tappet arrangement in a combustion engine. The cam follower (4) comprises a primary device (8), a secondary device (10) and a lock component (13), which is attached on one of said devices (10) and comprises a contact surface (13c 1 ), adapted to be moved into engagement with a contact surface (8a 1) of the second of said devices (8). The lock component (13) is applicable in an unlocked position, in which steering motions from the secondary device (10) are not transmittable to the primary device (8) via the said contact surfaces (8a 1 , 13c 1 ), in a partly locked position and in a fully locked position, in which steering motions from the secondary device (10) are transmittable to the primary device (8) via said contact surfaces (8a 1 , 13c 1 ). The contact surfaces (8a 1 ,13c 1 ) have a complementary shape. They are not in full contact with each other in the partly locked position and are in full contact with each other in the fully locked position. They have a gradient in relation to each other in the partly locked position, so that, when a steering motion from the secondary device (10) is applied to said contact surfaces (8a 1 , 13c 1 ) being in the partly locked position, the lock component's contact surface (13c 1 ) will be adjusted in relation to the second contact surface (8a0, until the contact surfaces (8a 1 , 13c 1 ) are in full contact with each other and the lock component (13) is in the fully locked position.

摘要： The invention relates to a method for changing gear ratio in a gearbox (4) of a vehicle (1). The method comprises the steps of: a) receiving a first signal (S1) that the gear ratio should be changed; b) calculating the braking torque that the internal combus- tion engine (2) should provide in order to reduce the rotational speed of the internal combustion engine (2) to a target rotational speed at which the internal combustion engine (2) should be running after the gear ratio has been changed; c) phase-shifting the at least one second camshaft (28) in relation to the crankshaft (16), so that the at least one second camshaft (28) is phase-shifted to a state, where the at least one exhaust valve (24) is controlled in such a way, that it is opened during the expansion stroke of the internal combustion engine (2) and closed during the exhaust stroke of the internal combustion engine (2); d) disconnecting the internal combustion engine (2) from the at least one driving wheel (6); e) opening and closing the at least one exhaust valve (24) with a decompression device in the transition area between an exhaust stroke and an inlet stroke and also between a compression stroke and an expansion stroke, when the piston (12) is at a top dead centre in the cylinder (10) in order to achieve engine braking through compression in the cylinders (10) during the exhaust stroke and the compression stroke, and f) shifting gear in the gearbox (4). The invention also relates to a vehicle (1) comprising a gearbox (4) in which the gear ratio is changed by the method. (Fig. 4)
