Detailed Description

Embodiments of the present utility model will be described in detail below, by way of example with reference to the accompanying drawings.

A gasket 1 according to an embodiment of the present utility model, which gasket 1 is applied to a transmission, will be described with reference to fig. 1 to 4.

As shown in fig. 1 and 2, a gasket 1 according to the present utility model includes: base plate 2 and cushion 3, cushion 3 set up on base plate 2, be provided with integrated into one piece's spacer pin 4 on the cushion 3 to can be used for spacing cooperation with the casing. It can be understood that the base plate 2 is the skeleton structure of the sealing gasket 1, the rubber cushion 3 is located on the inner side of the base plate 2, and the limiting pin 4 is arranged on the rubber cushion 3, so that the limiting pin 4 and the rubber cushion 3 are integrally formed, the limiting pin 4, the rubber cushion 3 and the base plate 2 are connected into a whole, and the sealing gasket 1 and the shell are in limiting fit through the arrangement, namely, after the sealing gasket 1 and the shell are assembled, the coating of the rubber cushion 3 can be pressed close to the joint surface of the shell, so that the sealing gasket 1 can realize sealing effect, and the falling of the sealing gasket 1 can be prevented. From this, through integrated into one piece spacer pin 4 on cushion 3, cushion 3 sets up on base plate 2 moreover to be convenient for base plate 2 and the spacing cooperation of casing, set up like this and be convenient for not only sealed pad 1 and the installation of casing end face, the derailleur is in the equipment upset in-process moreover, spacer pin 4 can the joint casing, thereby makes sealed pad 1 keep normal position and can not drop. Moreover, the sealing gasket 1 arranged in this way does not need to upgrade equipment, and the cost can be reduced.

As shown in fig. 1-3, an avoidance hole 21 with an opening is formed on the substrate 2, the rubber pad 3 is integrally vulcanized on the substrate 2, and the limiting pin 4 is located at the avoidance hole 21. That is, the avoiding hole 21 is located on the substrate 2, and the avoiding hole 21 is close to the limiting pin 4, so that when the rubber is vulcanized, the rubber is vulcanized along the inner side of the substrate 2, and when the rubber is vulcanized to the avoiding hole 21, the rubber flows in along the avoiding hole 21, so that the limiting pin 4 is formed, and the limiting pin 4 and the rubber pad 3 are integrally vulcanized on the substrate 2.

In particular, as shown in fig. 3, the escape hole 21 is located at the inner edge of the substrate 2, that is, the escape hole 21 is located on the edge of the substrate 2, and the escape hole 21 is located near the center side of the substrate 2, so that the rubber is facilitated to flow into the formation stopper pin 4 from the escape hole 21, that is, the rubber pad 3 and the stopper pin 4 are facilitated to be integrally vulcanized, thereby improving the integration of the gasket 1 and facilitating the manufacture of the gasket 1.

Alternatively, as shown in fig. 3 and 4, the number of the limiting pins 4 is at least two, and at least two limiting pins 4 are disposed on opposite sides of the rubber pad 3. It can be understood that the limiting pin 4 is located on the symmetrical side of the rubber pad 3, and the limiting pin 4 is located on the side of the avoiding hole 21, so that the rubber pad 3 and the limiting pin 4 are integrally vulcanized, and the positioning and the installation between the sealing gasket 1 and the shell are also facilitated.

Wherein, as shown in fig. 3 and 4, the limiting pin 4 is disposed on the side edge of the rubber pad 3 adjacent to the end of the side edge, for example, the limiting pin 4 may be located at a symmetrical angle of the rubber pad 3, so that the rubber is vulcanized from the avoiding hole 21 to form the rubber pad 3 and the limiting pin 4, so that the limiting pin 4 and the rubber pad 3 are integrally formed, and the sealing pad 1 is aligned with the end face of the shell.

Further, as shown in fig. 3 and 4, the gasket 1 further includes: the reinforcing pin 5 has a through hole 41 formed in the stopper pin 4, and the reinforcing pin 5 is provided in the through hole 41. It will be appreciated that the reinforcing pin 5 may be disposed through the through hole 41, so that the reinforcing pin 5 and the limiting pin 4 may be cooperatively connected, thereby facilitating assembly between the gasket 1 and the housing.

Wherein, as shown in fig. 3 and 4, the reinforcing pin 5 is a taper pin, and the reinforcing pin 5 is in interference fit with the through hole 41, and when the reinforcing pin 5 is inserted into the limiting pin 4, the reinforcing pin 5 can squeeze the limiting pin 4, so that the rubber pad 3 can be tightly attached to the inner wall of the shell hole, and the sealing gasket 1 can be prevented from falling off.

Alternatively, as shown in fig. 1 and 2, the thickness of the substrate 2 is d1, the thickness of the rubber pad 3 is d2, and d1 and d2 satisfy the relation: 1.5d1.gtoreq.d2.gtoreq.d1. That is, the relationship between the thickness of the substrate 2 and the thickness of the cushion 3 needs to be within a certain range, if the thickness of the cushion 3 is smaller than the thickness of the substrate 2, the substrate 2 is directly connected with the joint surface of the housing, so that the housing cannot be sealed by using the gasket 1, and if the thickness of the cushion 3 is greater than 1.5 times the thickness of the substrate 2, the cushion 3 is too thick, so that the sealing effect of the gasket 1 on the housing is reduced, and the cushion 3 can be closely compressed with the joint surface of the housing, so that the sealing effect on the housing is realized.

A transmission according to an embodiment of the present utility model includes: the sealing gasket 1 of the embodiment above and the casing is provided with the spacing hole, and the spacing pin 4 cooperates with the spacing hole in a spacing way, so that the setting can lead the sealing gasket 1 to be aligned with the spacing hole in the assembly process of the casing, thereby being convenient for assembly, and the casing can also prevent the sealing gasket 1 from falling off in the overturning process.

According to an embodiment of the present utility model, a vehicle includes: according to the transmission of the embodiment, the integrally vulcanized rubber pad 3 and the limiting pins 4 are arranged on the base plate 2, so that positioning and assembling between the base plate 2 and the shell are facilitated, and the reinforcing pins 5 are arranged after the assembling is finished, and therefore the rubber pad 3 of the transmission can be prevented from falling off in the overturning process.
