Problems solved by technology

[0004] In a family car, the gearbox is one of the three important parts. The quality of the gearbox determines the quality of the vehicle's handling. When the transmission components in the gearbox are engaged for a long time, a lot of heat will be generated. Changing the size of the transmission components affects the meshing and reduces the handling quality
In the past, the gearbox used cooling fins to cool down the gearbox, but the space in the car body is limited. To increase the cooling rate, the heat dissipation area must be increased, which creates a contradiction between saving space in the car and improving the heat dissipation effect.

Embodiment 1

[0029] This embodiment provides a gearbox case for rapid heat dissipation, including a case body 1, a base 2, and a heat dissipation assembly, wherein:

[0030] The base 2 is composed of left and right seats, the left and right seats are fixedly connected to the left and right sides of the bottom of the shell body 1 respectively, and the base 2 is fixedly installed on the upper end of the longitudinal beam of the vehicle body;

[0031] The heat dissipation assembly includes a power fan 3, an acceleration air duct 4, a suction fan 5, an exhaust fan 6, a heat conduction assembly 7, an air delivery channel 8, and a transmission assembly 9. The acceleration air duct 4 is fixedly installed in the middle of the bottom of the shell body 1 to The area of ​​the air inlet of the channel 4 is larger than the area of ​​the air outlet. The power fan 3 is installed on the outer bottom of the shell body 1 and is located in the middle of the acceleration air channel 4. The air delivery channel...

Abstract

The invention discloses a rapid heat dissipating type gearbox housing. The rapid heat dissipating type gearbox housing comprises a housing body, a base and a heat dissipating assembly, wherein the base comprises a left seat and a right seat which are correspondingly fixedly connected to the left side and the right side of the bottom part of the housing body; the base is fixedly mounted at the upper end of a longitudinal beam of a vehicle body; the heat dissipating assembly comprises a power fan, an acceleration air channel, an air draft fan, an air exhausting fan, a heat transferring assembly,air conveying channels and a transmission assembly; the acceleration air channel is fixedly mounted in the middle part of the bottom part of the housing body; the area of an air inlet of the acceleration channel is more than that of an air outlet; the power fan is rotatably mounted at the outer bottom part of the housing body and is positioned in the middle part of the acceleration air channel; the air conveying channels are symmetrically distributed on two inner side surfaces and the inner bottom surface of the housing body; the air conveying channels are provided with a plurality of air inlets, and the air inlets are symmetrically arranged at two ends of the air conveying channels. According to the scheme, the rapid heat dissipating type gearbox housing has the advantage that the heat dissipating efficiency is greatly improved while the size of the gearbox housing remains.

Description

technical field [0001] The invention relates to the technical field of gearboxes, in particular to a gearbox casing for rapid heat dissipation. Background technique [0002] The gearbox mainly refers to the gearbox of the car, which is divided into manual and automatic. The manual gearbox is mainly composed of gears and shafts, and the variable speed and torque are generated through different gear combinations; It is composed of torque converter, planetary gear, hydraulic pitch change system and hydraulic control system. Variable speed and torque are achieved through hydraulic transmission and gear combination. [0003] The gearbox is a very important part of the vehicle. It can change the transmission ratio and expand the torque and speed of the driving wheels. With the development of modern technology, the gearbox has also been upgraded. From the initial manual gearbox to the current stepless gearbox, from no synchronizer to synchronizer, the operation is more and more c...
