Abstract

The invention provides an AMT gearbox, which relates to the field of vehicles. The AMT gearbox is characterized by comprising a front shell, a brake bearing cover, a cylinder cover and a brake piston, wherein the brake bearing cover and the cylinder cover are fixedly connected to the front shell, a mounting inner cavity is formed between the brake bearing cover and the cylinder cover, a friction plate and a brake plate are arranged in the mounting inner cavity, the shaft end part of an intermediate shaft extends into the mounting inner cavity, and the friction plate and the brake plate are mounted at the shaft end part of the intermediate shaft; and an oil storage disc is installed on the front shell, a first oil channel is formed in the front shell, the oil storage disc is communicated with the first oil channel, a second oil channel is formed in the brake bearing cover, one end of the second oil channel is communicated with the first oil channel, the other end of the second oil channel is communicated with the mounting inner cavity, and oil return grooves are formed in the brake bearing cover and the bottom part of the front shell, so that lubricating oil in the oil storage disc can sequentially flow into the first oil channel, the second oil channel and the mounting cavity under the action of its gravity.

Description

Technical field [0001] The present invention relates to the field of vehicle, and more particularly to an AMT gearbox. Background technique [0002] The gear, bearing, synchronizer in the heavy truck, even the brake used by the AMT gearbox, generally enhances forced lubrication by increasing the oil pump. The gearbox used in the middle card is small, and the splash lubrication can basically meet the lubrication of the transmission, and the need for oil pump is not high and can result in an increase in manufacturing cost. [0003] In particular, when the vehicle is driving in the steep slope, a small portion of the transmission member is higher than the oil plane and the splashing oil in the transmission is limited, and the heat generated cannot be taken in time, resulting in ablation of parts. The AMT transmission brake is in operation frequently (the gear process) operating due to lack of lubrication due to lack of lubrication. This is the current state of the prior art. [0004...
