Abstract

The invention relates to transmission shafts in vehicle parts, particularly to a shaft sleeve type cross shaft. The shaft sleeve type cross shaft comprises a cross shaft frame; a cross oil channel and an oil inlet channel are formed in the cross shaft frame; the oil inlet channel is communicated with the cross oil channel; sealing rings, shaft sleeves and shaft sleeve seats sleeve four shaft heads respectively. The shaft sleeve type cross shaft is characterized in that the rear end of every shaft head is provided with a stop shaft shoulder; the front end of every shaft head is of a step structure; the inner circle surfaces of the shaft sleeves are provided with a plurality of oil grooves; the sealing rings abut against the stop shaft shoulders of the shaft heads; the shaft sleeves and the shaft heads are assembled separately; the shaft sleeves and the shaft sleeve seats are assembled in an interference mode; the shaft sleeve seats and the shaft head step surfaces form oil storage chambers; the oil grooves formed in the shaft sleeves are communicated with the oil storage chambers. The shaft sleeve type cross shaft has the advantages of being simple in structure, convenient to install, good in lubrication effect, free of abnormal noise and abrasion, abrasion-resistant and durable and suitable for improvement of transmission shaft universal joints of various vehicle models.

Description

technical field [0001] The invention relates to a transmission shaft of a vehicle part, in particular to a bushing type cross shaft. Background technique [0002] The universal joint cross shaft in the existing vehicle has a structure in which needle roller bearings and bearing seats are assembled on the four shaft heads of the cross shaft frame, and the bearing seat is a two-stage split assembly structure. The disadvantage is that the structure It is complicated, inconvenient to install, easy to wear, and needs to be lubricated frequently. Contents of the invention [0003] The purpose of the present invention is to overcome the problems of complex structure, inconvenient installation, easy wear and frequent lubrication of the existing transmission cross shaft, and provide a new type of bushing type cross shaft. [0004] The specific solution of the present invention is: to improve the existing cross shaft, it has a cross shaft frame, a cross oil passage is opened in the...
