Problems solved by technology

The former takes up a lot of space, and often cannot be matched with the whole vehicle normally, and the moment of inertia of the cover assembly is large, which will further aggravate the impact damage; the installation space of the latter is allowed, but it requires the driven plate to be able to withstand huge impacts, often causing the spring or even the entire slave to be damaged. The damping structure of the moving plate is broken, and the service life is short; the effect of the hydraulic torsional damper is better, but the cost is too high

Embodiment

[0017] like Figure 1-3 As shown, a torsional shock absorber for a hybrid vehicle includes a driven disc 4, and also includes a friction disc 3 and a disc spring 2 stacked from bottom to top on the friction plate 4-1 of the driven disc 4 And cover 1, cover 1 covers the disc spring 2 and friction disc 3, the outer ring of cover 1 is provided with mounting holes 1-1, the inner ring is provided with claws 1-2, and the inner ring of friction disc 3 is provided with clamps Slot 3-1, the card slot 3-1 is adapted to the claw 1-2.

[0018] There are at least two jaws 1-2.

[0019] The size of the outer circle of the friction disc 3 is greater than or equal to the size of the outer circle of the friction plate 4-1.

[0020] The center position of the friction disc 3 is stacked with the center position of the driven disc 4 .

[0021] There are at least two mounting holes 1-1.

[0022] Install the shock absorber on the flywheel. When the output torque of the engine or motor is small,...

Abstract

The invention discloses a torsion damper for a hybrid electric vehicle. The torsion damper comprises a driven plate and friction discs, disc springs, and covers which are sequentially overlapped on friction plates of the driven plate from bottom to top; and the covers cover the disc springs and the friction discs, the outer rings of the covers are provided with mounting holes, the inner ring edgesof the covers are provided with clamping claws, the inner rings of the friction discs are provided with necks, and the necks are matched with the clamping claws. The absorber transmits torque and unloads impact and is light in weight, small in rotational inertia, small in installation space, simple and reliable in structure, and low in cost.

Description

technical field [0001] The invention relates to a hybrid power system for automobile manufacturing, in particular to a torsional shock absorber for a hybrid power vehicle. Background technique [0002] In the existing hybrid power system of passenger cars, there is a great impact on the torque transmission between the engine and the motor. If they are directly connected by a shaft, it is easy to cause a broken shaft. Therefore, the driven disc in a conventional clutch or a separate clutch is often used to connect the engine and the motor. The former takes up a lot of space, and often cannot be matched with the whole vehicle normally, and the moment of inertia of the cover assembly is large, which will further aggravate the impact damage; the installation space of the latter is allowed, but it requires the driven plate to be able to withstand huge impacts, often causing the spring or even the entire slave to be damaged. The damping structure of the moving plate is broken, an...
