[0025] Now the utility model is further described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.

[0026] Embodiment 1, the utility model provides a gasket for hybrid and electric vehicle gearboxes, comprising: an inner concave surface 101; and an outer convex surface 102 corresponding to the inner concave surface 101; wherein an oil storage portion 104 is provided on the inner concave surface 101; and the oil storage portion 104 comprises a plurality of rhombus-shaped grooves. The interior of the rhombus-shaped grooves is filled with lubricating oil. The rhombus-shaped grooves are arranged at equal intervals on the inner concave surface 101. The diagonal lines of the rhombus-shaped grooves face the center direction of the gasket 100. By providing the rhombus-shaped grooves with the diagonal lines facing the center of the gasket, the probability of sintering of the gasket during use is reduced. A positioning hole 103 is provided at the center position of the gasket 100.

[0027] Embodiment 2: The utility model provides a gasket for a hybrid or electric vehicle gearbox, comprising: an inner concave surface 101; and an outer convex surface 102 corresponding to the inner concave surface 101; wherein an oil storage portion 104 is provided on the inner concave surface 101; and the oil storage portion 104 comprises a plurality of rhombus-shaped grooves. The interior of the rhombus-shaped grooves is filled with lubricating oil. The rhombus-shaped grooves are arranged at equal intervals on the inner concave surface 101. The diagonal lines of the rhombus-shaped grooves face the center direction of the gasket 100. By setting the rhombus-shaped grooves with the diagonal lines facing the center of the gasket, the probability of sintering during the use of the gasket is reduced. A positioning hole 103 is provided at the center position of the gasket 100. The positioning hole 103 is a waist-shaped hole. The waist-shaped hole allows the gasket 100 to have a good positioning effect during assembly and enhances assembly accuracy.

[0028] Embodiment 3, the utility model provides a gasket for a hybrid and electric vehicle gearbox, comprising: an inner concave surface 101; and an outer convex surface 102 corresponding to the inner concave surface 101; wherein an oil storage portion 104 is provided on the inner concave surface 101; and the oil storage portion 104 includes a plurality of rhombus grooves. The depth of the rhombus groove is 0.1mm. The rhombus groove cannot be too large or too small, so the side length of the rhombus groove is 1mm-3mm, which can avoid the phenomenon of high contact surface pressure caused by too large rhombus grooves, and also solve the problem of no lubrication due to too small rhombus grooves. The distance between two adjacent rhombus grooves is 0.5mm. The inside of the rhombus groove is filled with lubricating oil. The rhombus grooves are arranged on the inner concave surface 101 at equal intervals. The diagonal of the rhombus groove faces the center direction of the gasket 100. By setting the rhombus groove with the diagonal facing the center of the gasket, the probability of sintering during the use of the gasket is reduced. A positioning hole 103 is provided at the center of the gasket 100. The positioning hole 103 is a waist-shaped hole, which provides a good positioning effect when the gasket 100 is assembled, thereby enhancing assembly accuracy.

[0029] Embodiment 4, the utility model provides a gasket for hybrid and electric vehicle gearboxes, comprising: an inner concave surface 101; and an outer convex surface 102 corresponding to the inner concave surface 101; wherein an oil storage portion 104 is provided on the inner concave surface 101; and the oil storage portion 104 includes a plurality of rhombus grooves. The depth of the rhombus groove is 0.1mm. When the side length of the rhombus groove is 1.2mm, the contact surface friction of the gasket 100 is the smallest, and the lubrication effect is the best. The distance between two adjacent rhombus grooves is 0.5mm. The inside of the rhombus groove is filled with lubricating oil. The rhombus grooves are evenly spaced on the inner concave surface 101. The diagonal of the rhombus groove faces the center direction of the gasket 100. By setting the rhombus groove with the diagonal facing the center of the gasket, the probability of sintering during the use of the gasket is reduced. A positioning hole 103 is provided at the center of the gasket 100. The positioning hole 103 is a waist-shaped hole. The waist-shaped hole provides a good positioning effect for the gasket 100 during assembly, thereby enhancing assembly accuracy.

[0030] In summary, by setting a diamond groove with a diagonal line toward the center of the gasket 100, the probability of sintering of the gasket 100 during use is reduced; by setting the side length of the diamond groove to 1.2 mm, the phenomenon of high contact surface pressure due to the diamond groove being too large is avoided, and the problem of no lubrication due to the diamond groove being too small is solved; by setting a waist-shaped hole at the center position of the gasket 100, a good positioning effect is achieved during the assembly of the gasket 100, thereby enhancing the assembly accuracy.
