Description

Drive shaft separator

The present invention relates to a drive shaft splitter, and more particularly to a drive shaft splitter that does not take up space and can provide a drive shaft of each brand for disassembling the joint mandrel and the rotating sleeve.

According to the conventional automobile system, a dust jacket is arranged between the joint mandrel of the wheel drive shaft and the rotating sleeve to prevent foreign matter such as dust and sand from entering between the joint mandrel and the rotating sleeve, and when the dust jacket is damaged, When the foreign matter enters the joint between the joint mandrel and the rotating bushing from the damaged portion of the boot, the foreign matter adheres to the bearing of the rotating bushing, etc., which affects the smooth running of the bearing and even causes the bearing to be damaged. When the bearing of the rotating bushing is damaged, it must be replaced. Conventionally, when the joint mandrel and the drive bushing of the drive shaft are disassembled, the drive bushing is mainly separated from the joint mandrel by a hammer hitting method, but the construction method is not only time-consuming but also easy to join the mandrel, etc. Cause damage.

Therefore, the manufacturer has developed and provided the rotating bushing and the engaging mandrel dismounting device. Please refer to the "Automobile Transmission Shaft Dismounting Device" of China Announcement No. 391341, which mainly comprises a fixing plate, a set of positioning clamp arms and a tightening ring. Two sets of positioning clip arms are fixed on opposite sides of the fixing plate, and are fixed to the tightening ring at the front and rear inclined body ends of the set of positioning clip arms. The tightening ring is separable and has convex on both sides. The ear can be screwed through the perforation lock or the upper and lower lugs can be clamped by the clamp, and the joint shaft of the drive shaft can be fixed, and the jack in the center of the fixed plate can be used for the rotation shaft sleeve of the drive shaft. The shaft is partially erected on the socket, and is screwed and screwed with the threaded portion, thereby detaching the rotating sleeve from the engaging mandrel.

The use of the "Automotive Transmission Shaft Removal Device" of China's Announcement No. 391341 can disassemble and disengage the coupling mandrel of the transmission shaft from the transmission bushing in a time-saving and labor-saving manner. However, the "Announcement of China's Announcement No. 391341" The length of the two-position clamping arm of the transmission shaft dismounting device is fixed, and the length of the connecting mandrel of the different brand vehicles is different from that of the rotating bushing. Therefore, it is difficult to provide different positions for the fixed-length positioning arm design. The branded vehicle has its joint mandrel and rotating sleeve disassembled, and its two positioning clip arms also occupy a considerable space, which is easy to interfere with other components of the vehicle, which makes it difficult to install and use, and different brands The rotating shaft sleeve has different diameters of the supporting shafts. However, the fixing plate of the "automobile transmission shaft dismounting device" of the Chinese Patent No. 391341 has only a fixing hole of the fixing hole to provide the supporting shaft of the rotating sleeve. Therefore, only the specific brand rotating bushing that conforms to the hole diameter of the fixing plate of the fixing plate can be used together, which also causes the use of the automobile transmission shaft dismounting device to be restricted, and the user has to respond differently. The rotation of the sleeve licensing acquisition means matches the cars detached drive shaft, increasing the cost burden.
