Double-blade swing hydraulic motor for driving stabilizing rod

Abstract

The invention relates to a double-blade swing hydraulic motor for a driving stabilizing rod. The double-blade swing hydraulic motor for the driving stabilizing rod comprises an output shaft, a cylinder body, a front end cover and a rear end cover, wherein stator blades are symmetrically arranged in the cylinder body, and rotor blades are symmetrically arranged on the output shaft; the stator blades and the cylinder body are of an integrated structure, and the rotor blades and the output shaft are of an integrated structure; oil cavity channels are formed in the two sides of each rotor blade so that oil cavities which are arranged in an opposite mode can be communicated; interior sealing devices are arranged in the middle of each stator blade and the middle of each rotor blade. Each interior sealing device comprises a leaf spring, a sealing frame and sealing sheets. The front end cover comprises oil ports, exhaust holes and a front end cover locating pin hole. Shaft sleeves, axial sealing devices, shaft step seals and dust rings are arranged in the front end cover and the rear end cover. Each axial sealing device comprises a wavy leaf spring, a conical gasket and a sealing ring. The double-blade swing hydraulic motor for the driving stabilizing rod is simple and compact in structure, small in size, light in weight and low in manufacturing cost, can ensure high-pressure sealing of the oil cavities, and can also meet the performance requirement of the driving stabilizing rod.

Description

technical field [0001] The invention belongs to the technical field of vehicle safety, and in particular relates to a double-blade swing hydraulic motor used for an active stabilizer bar. Background technique [0002] The vehicle chassis system must provide the driver with the best driving comfort, high driving safety and maximum handling simplicity, among which vehicle roll is one of the important factors affecting comfort and safety. As an important safety component of the independent suspension system of a car, the active stabilizer bar can improve the stability of the operation when the car turns or encounters resistance, and prevents excessive lateral roll of the body. The hydraulic motor acts as the actuator of the active stabilizer bar. When the vehicle turns or encounters resistance, the hydraulic system drives the hydraulic motor to output torque to drive the stabilizer bar to swing to prevent the body from rolling. The hydraulic motor plays a vital role in the who...

Problems solved by technology

Patent No. ZL 90203233.X's "Blade Swing Motor" technical solution: use positioning pins to connect the stator to the front and rear end covers; install the rotor in the corresponding slot on the output shaft and fasten it with pin positioning screws; use screws to connect the front cover , the rear cover and the cylinder body are connected together; the stator uses oil-resistant rubber or polyurethane closed rectangular seal ring, and the rotor uses oil-resistant rubber or polyurethane open rectangular seal ring; the output shaft is supported by bearings; although it can relieve the double-blade motor to a certain extent However, there is still a high-pressure leakage problem. The nominal pressure of the motor is only 6.3MPa; at the same time, there are problems of complex assembly and excessive volume and weight, which make the motor unable to be used in active stabilizer bars.

[0004] It can be seen that domestic double-blade swing motors generally have disadvantages such as high-pressure leakage, low load-carrying capacity, poor impact resistance, and excessive weight.

At present, there is no dual-blade swing hydraulic motor suitable for active stabilizer bars
