Description
Technical field
The utility model relates to automobile technical field, is specifically related to a kind of double mass flywheel and automobile.
Background technique
In car transmissions, double mass flywheel is usually used to realize shock-absorbing function; Original flywheel is divided into two parts by double mass flywheel, a part is retained on the position of original motor side, play the effect of original flywheel, for starting and transmit the driving torque of motor, this part is called the first mass flywheel, another part is then placed on transmission system gear shift device side, and for improving the rotary inertia of transmission side, this part is called the second mass flywheel.There is the oil pocket that ring-like between two-part flywheel, in chamber built with spring cushion, by spring cushion, two-part flywheel is connected as a whole.
With reference to figure 1, the first mass flywheel 10 in double mass flywheel is provided with the first bolt hole 11, the bent axle of motor (scheming not shown) is also provided with accordingly the tapped hole mated with the first bolt hole 11, by construction bolt in the first bolt hole 11, the first mass flywheel 10 is installed on the bent axle of motor; The center position of the first mass flywheel 10 is provided with bearing 20, sheathed flange 30 on bearing 20, the second mass flywheel 40 in double mass flywheel is arranged on flange 30 by rivet 50, second mass flywheel 40 is provided with the second bolt hole 41, be connected with the second mass flywheel 40 by the clutch cover of construction bolt in the second bolt hole 41 by clutch (scheming not shown), simultaneously, the end face 42 of clutch sector-meeting and the second mass flywheel 40 is fitted, and the second mass flywheel 40 just can to clutch transferring power; Oil pocket is formed between first mass flywheel 10 and the second mass flywheel 40, for mounting spring vibration damper 60, in the process of the first mass flywheel 10 High Rotation Speed, spring damper 60 is compressed thus the driving torque of motor is passed to the second mass flywheel 40, reaches damping effect.
In addition, when motor works in the presence of a harsh environment, there is the phenomenon of the fluctuation of speed, now also need on the first quality loop 10, to increase quality loop 70, to improve the fluctuation of speed of motor.
In prior art:
1., when the first mass flywheel 10 connects from different motors, because the interface size of bent axle and the first mass flywheel 10, engine rear end face are different, need mold developing again, the cycle is longer, costly; Such as, the Crankshaft Sizes of motor is different, first mass flywheel 10 is to be arranged on the bent axle of different motors, need size and the position of the first bolt hole 11 on change first mass flywheel 10, after the size of the first bolt hole 11 and position change, will mold developing again, design cost is high;
2. the size of the second bolt hole 41 when the second mass flywheel 40 connects from different clutch plate, first, on the second mass flywheel 40 can change; Secondly, the end face 42 of second mass flywheel 40 of fitting with clutch plate also can change thereupon; Like this, the mould again developing the second mass flywheel 20 is also needed;
3., for the oil pocket of mounting spring vibration damper 60, formed by the first mass flywheel 10 and the second mass flywheel 40; The shape of the shape of the first mass flywheel 10 and the second mass flywheel 40 and structures shape oil pocket and structure, thus also just determine shape and the structure of the spring damper 60 that will install; In other words, in double mass flywheel, the shape of the spring damper 60 installed and structure are by the first mass flywheel 10 and the shape of the second mass flywheel 40 and the impact of structure.After the mould again developing the first mass flywheel 10 or the second mass flywheel 40, structure and the shape of the first mass flywheel 10 or the second mass flywheel 40 change, structure and the shape of the oil pocket that the first mass flywheel 10 and the second mass flywheel 40 certainly will be caused to be formed also can change, and the structure of spring damper 60 and shape also need to change then;
4., when changing the shape of spring damper 60 and structure, also to change for the structure of the oil pocket of mounting spring vibration damper 60 and shape; So, form the first mass flywheel 10 of oil pocket or the structure of the second mass flywheel 40 and shape also to need to change.
To sum up, the first mass flywheel 10, second mass flywheel 40 and spring damper 60 are after one of them changes, and other parts need to be changed accordingly, and add development cost.
