Embodiment Construction

[0012] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:

[0013] Such as figure 1 , 2 As shown, a main transmission gear of a second-speed electric vehicle transmission assembly, the main transmission gear body 1 is made of 20CrMnTiH, and is formed by forging. At the same time, the thickness of the body 1 is 22 mm, the diameter of the central hole of the body 1 is 95 mm, and the outer edge of the body 1 is in the shape of a ring of teeth. The center of the left end surface of the main body 1 is provided with a first weight reducing groove 1a, the diameter of the first weight reducing groove 1a is 147mm, and the depth of the first weight reducing groove 1a is 14mm. The center of the right end surface of the main body 1 is provided with a second weight reducing groove 1b, the diameter of the second weight reducing groove 1b is 147mm, and the depth of the second weight reducing groove 1b is 2mm. The body 1 is evenly...

Abstract

The invention discloses a main drive gear of a two-gear electric vehicle transmission assembly. A main drive gear body is 22 millimeters in thickness, and the outer edge of the body is provided with a circle of teeth; a first weight reduction groove is opened in the center of the left head face of the body, and the first weight reduction groove is 147 millimeters in diameter and 14 millimeters in depth; a second weight reduction groove is opened in the center of the right head face of the body, and the second weight reduction groove is 147 millimeters in diameter and 2 millimeters in depth; 8 bolt mounting holes are uniformly opened in the body along the circumferential direction, the aperture of each bolt mounting hole is 11 millimeters, and ends of the bolt mounting holes are opened in the bottoms of the first and second weight reduction grooves. The main drive gear sleeves a drive shaft through a central hole and is firmly connected through bolts through arranged in the 8 bolt mounting holes, when driving, power is transmitted through the tooth shape of the edge of the outer circle, and the drive is reliable; because the main drive gear of the two-gear electric vehicle transmission assembly is provided with the first weight reduction groove and second weight reduction groove, the weight is reduced effectively based on guaranteeing the structure intensity.

Description

technical field [0001] The invention belongs to the field of transmission assembly, and in particular relates to a main transmission gear of a second-speed electric vehicle transmission assembly. Background technique [0002] The existing electric vehicle transmission assembly has only one gear position, that is, it cannot change speed, its output speed and torque are constant, and it cannot be adjusted accordingly according to the road conditions, which leads to its poor adaptability to road conditions. [0003] In order to improve the road condition adaptability of the transmission, it is now necessary to redesign an electric vehicle transmission assembly with two gears. At the same time, in the design process, it is necessary to design a main transmission gear accordingly. The main transmission gear must not only be able to be installed firmly, but also need to be able to transmit power reliably, and also needs to be compact in structure and light in weight.
