The utility model has the advantages of simple overall structure, reduce the assembly step, reduce overall structure cost, also can play the cushioning effect of the in-process of shifting.
Description
Technical Field
The utility model belongs to the technical field of the clutch piston, especially, relate to a clutch piston structure.
Background
At present, in the existing clutch structure, an oil charging cavity is formed by a piston and the side wall of a shell, and the piston generates thrust under the action of oil pressure to combine and separate a steel sheet and a friction plate, so that the separation and combination functions of the clutch are realized. In order to prevent the gear shifting impact caused by instantaneous combination in the gear shifting process, a wave spring is needed between the piston and the steel sheet for buffering during gear shifting. Because a wave spring is required, an additional assembly step is added in the assembly process, the cost of the clutch is increased, and the weight is increased correspondingly.
Therefore, the prior art is to be improved.
SUMMERY OF THE UTILITY MODEL
The utility model discloses a main aim at provides a clutch piston structure, aims at solving the technical problem that the background art mentioned to reduce the assembly step, reduce overall structure cost, also can play the cushioning effect of the in-process of shifting.
The utility model discloses a clutch piston structure, including casing, jump ring, ring gear, friction disc, steel sheet and the piston of setting in the casing, be provided with the first extension of transversal personally submitting curve on the piston, the friction disc sets up on the steel sheet, is provided with the interval between steel sheet and the first extension, and the ring gear sets up on the friction disc.
Preferably, the friction plates and the steel plates are stacked alternately in the vertical direction.
Preferably, the piston top is disposed on the housing bottom and the first extension is disposed on the piston bottom.
The utility model discloses a clutch piston structure has following beneficial effect:
based on the structural improvement of the piston, namely, the piston is provided with a first extension part with a curved cross section, the steel sheet is connected with the first extension part, and the first extension part is used as a force arm to enable the first extension part to deform a little under the action of oil pressure; before the friction plate and the steel sheet are completely combined, the piston deforms firstly and then pushes the friction plate and the steel sheet to be completely combined, so that the buffer effect in the gear shifting process is achieved.

These terms are only used to distinguish one component from another component. For example, a first element could be termed a second element, and, similarly, a second element could be termed a first element, without departing from the scope of the present invention. The term "and/or" refers to a combination of any one or more of the associated items and the descriptive items.
As shown in fig. 1 and 2; fig. 1 is a schematic structural diagram of a clutch piston structure of the present invention; fig. 2 is a schematic structural diagram of a piston in the clutch piston structure of the present invention.
The utility model discloses a clutch piston structure, including casing 10, jump ring 16, ring gear 11, friction disc 12, steel sheet 13 and the piston 15 who sets up in casing 10, be provided with the first extension 14 that the cross section is curved on piston 15, friction disc 12 sets up on steel sheet 13, is provided with the interval between steel sheet 13 and the first extension 14, ring gear 11 sets up on friction disc 12; more specifically, the first extension means a structure in which the piston bottom is extended in the radial direction, such as specifically, the first extension and the piston can be integrally formed by a punching process; the function is to elongate the boundary of the bottom of the piston, and the piston can be deformed under stress; the utility model discloses a clutch piston structure has following beneficial effect: based on the structural improvement of the piston, namely, the piston is provided with a first extension part with a curved cross section, the steel sheet is connected with the first extension part, and the first extension part is used as a force arm to enable the first extension part to deform a little under the action of oil pressure; before the friction plate is combined with the steel sheet, the piston deforms firstly and then pushes the friction plate to be combined with the steel sheet, so that the buffer effect in the gear shifting process is achieved. In contrast to the conventional clutch piston mechanism, which is described in the background of the invention, a wave spring 200 is provided on the conventional piston 100 as shown in fig. 3. The utility model reduces the wave spring and improves the gear shifting impact; the assembly of a part is reduced on the production line, the production line is simplified, and the beat efficiency is improved. The first extension and the piston are integrally formed by punching. As shown in fig. 4, the piston includes a rubber body 505 and a frame 506, and the first extension portion 14 is provided on the frame 506.
It should be noted here that the cross section is a curved first extension part, and the cross section is a curve, which is beneficial to subsequent deformation, and then the friction plate and the steel sheet are pushed to be completely combined, so as to achieve the buffer effect in the gear shifting process. Preferably, the friction plates and the steel plates are stacked alternately in the vertical direction. Preferably, the piston top is disposed on the housing bottom and the first extension is disposed on the piston bottom.
The above is only the preferred embodiment of the present invention, and not the scope of the present invention, all the equivalent structures or equivalent flow changes made by the contents of the specification and the drawings or the direct or indirect application in other related technical fields are included in the patent protection scope of the present invention.
