The well known motor car chassis including the power transmission, the travel is and the steering system, the power transmission part including the meeting and parting Transmission gearbox, drive shaft, driving axle, rear axle and driving gear. In power transmission these parts, to Gathering and the transmission gearbox are two most important parts without doubt. The pilot through operates the coupling already to be possible in The transmission gearbox shifts gears when causes the engine and the coupling separates temporarily, also may starts when the automobile cause the engine and Coupling steady joint. The coupling design used the disk spring to contract the organization, hydraulic control organization. In overseas, often uses the hydraulic control organization the coupling by to reduce pilot's weariness. Through to the drive shaft transmission type analysis, has carried on the shaping to the type of drive and the drive shaft; Through to the drive shaft type and the structure analysis, chose the drive shaft cross axle needle bearing seal form to cover the board style seal. Through to the universal joint cross axle, the needle bearing, the universal joint sliding yoke design calculation, had determined designs these parts concrete sizes which the vehicles uses. Synthesizes each part of designs and the check result, designs the coupling, the drive shaft can satisfy skin truck which designs to use the transport vehicle the transmission request.
