Abstract

The invention discloses a radial locking type over-load protection shaft which comprises a transmission shaft. The transmission shaft comprises a first shaft and a second hollow shaft, the first shaft is located in the second shaft and is concentric with the second shaft, at least one pair of hydraulic cylinders is arranged in the peripheral direction of the second shaft, an energy storage valve is connected between each pair of hydraulic cylinders, the hydraulic cylinders penetrate through a shaft wall of the second shaft, openings of the hydraulic cylinders face to the first shaft, ejecting blocks capable of sliding relative to cylinder bodies are arranged in the cylinder bodies of the hydraulic cylinders, and lugs butting against the ejecting blocks are arranged on the circumferential surface of the first shaft. The radial locking type over-load protection shaft can cut off power transmission during over-load so as to prevent the transmission shaft from being broken and simultaneously is good in reliability.

Description

[0001] technical field [0002] The invention belongs to the field of shaft transmission, and in particular relates to a transmission shaft structure with overload protection function, which is especially suitable for the transmission system of motor vehicles. [0003] Background technique [0004] In the field of mechanical transmission, especially in motor vehicles, the power generated by the engine needs to be transmitted to the wheels through the transmission system. For cars with front-engine front-wheel drive, the power of the engine is transmitted to the two half-shafts of the front axle through the transmission, final drive, differential, etc. to drive the wheels to rotate, while the car with front-engine rear-wheel drive That is to say, after the power passes through the transmission, it needs to be transmitted to the final drive of the rear axle through the main drive shaft. For off-road vehicles and trucks, in order to increase the climbing performance and passi...
