Embodiment Construction

[0030] The specific implementation manner of the present invention will be described in further detail below by describing the best embodiment with reference to the accompanying drawings.

[0031] The oil discharge method of the rack and pinion power steering gear comprises the following steps:

[0032] (1) Connect the connecting shaft 4 to the input end of the power steering gear 2, and connect the connecting shaft 4 to the servo motor 3; connect the compressed gas cylinder 6 to the oil inlet hole of the power steering gear 2; connect the oil return pipe 9 to the oil return hole of the power steering gear 2, The oil return pipe 9 is connected with an oil storage tank 10;

[0033] (2) The servo motor 3 rotates forward, the gear of the power steering gear 2 rotates to drive the rack and the piston to move to the side of the oil cylinder 21, and the piston moves to compress the oil in the oil cylinder 21, forcing the oil in the oil cylinder 21 to pass through the oil inlet pipe ...

Abstract

The invention discloses an oil discharge method and device of a pinion and rack type power steering gear. The oil discharge device is used for realizing the oil discharge method of the power steering gear, and comprises a servo motor and a supporting seat, wherein the servo motor is connected with an input end of the power steering gear through a connecting shaft; the supporting seat supports the power steering gear; an oil inlet hole in the power steering gear is connected with a compressed air cylinder; an oil return hole in the power steering gear is connected with an oil return pipe; and the oil return pipe is connected with an oil storage tank. According to the oil discharge method and device of the pinion and rack type power steering gear, under the control of the servo motor, a piston can reciprocate to the limit position, and thorough oil discharge is realized; the compressed air assists oil discharge, discharged test oil can be recycled, and the cost is saved; and full automatic operation is realized, and the working efficiency is high.

Description

technical field [0001] The invention relates to a rack and pinion power steering gear, in particular to an oil discharge method and an oil discharge device for a rack and pinion power steering gear. Background technique [0002] In the manufacturing process of the rack and pinion power steering gear, the essential key process is the comprehensive performance test. When conducting a comprehensive performance test, it is necessary to inject test hydraulic oil into the steering gear to simulate the working conditions of the vehicle. Due to the high cost of the test hydraulic oil, after the test, the test oil needs to be discharged for reuse. At present, the oil discharge for the test of the rack and pinion power steering gear is manually operated, which not only fails to drain the residual oil in the oil cylinder and pipeline, but also leads to waste of oil and complaints from the OEM assembly, and the oil discharge efficiency is low. Contents of the invention [0003] The p...
