Reverse idle gear lubrication structure of automobile transmission

摘要

The present invention relates to a reverse idler gear lubrication structure of a vehicle transmission to allow the reverse idler gear to rotate smoothly in a reverse shift of a vehicle. The conventional structure is not only less lubricating oil buried in the shaft (1 ') but also the shaft Since the lubricating oil cannot be stored in the self (1 ') itself, the lubricity of the reverse idler gear (3') and the bush (4 '), which rotates in the reverse shift, is deteriorated and the shaft (1') or the bush (4 ') There was a problem that the squeeze phenomenon or sticking phenomenon occurred. The oil storage groove 1a was formed on the upper side of the outer periphery of the shaft 1 'so that the oil storage groove 1a contained lubricating oil at the time of reverse shifting. According to the present invention, the lubricity of the reverse idler gear 3 is greatly improved at the time of reverse shift, according to the present invention, which can be supplied to the reverse idler gear 3. It is possible to prevent the seizure phenomenon or the seizure phenomenon of the driving bush bush 4 of these gears 3, thereby improving the performance of the transmission.
