For can concise description for the purpose of the problem, below the two Front Axle Steering Mechanism of the said car hosit of the utility model be all abbreviated as this steering hardware.
This steering hardware has obviously improved the safety of driving and the traveling comfort of manipulation: gimbal structure is all adopted in being connected between steering column and the angle deflector, between angle deflector and the direction machine; Manufacturing and installation error have been remedied, to adapt to the variable in distance that causes because of body distortion; The setting of three universal-joints can reduce to the fluctuation range of the variable speed transmission of universal-joint minimum; Adopt the version of single steering actuation cylinder, angle deflector, angle steering inner articulated shaft and the horizontally-mounted direction machine of level, the available buffer road surface is to the impact of steering hardware.
Use later-model optimization as this, the upper end of said front swing arm, the upper end of rear-swing arm are respectively hinged through tapered roller bearing and bearing.
Tapered roller bearing can carry the power of axis direction, makes intensity of this steering hardware and reliability improve.
The cylinder diameter of said direction machine is 120mm, and the length of plumbing arm is 300mm; The length of first longitudinal tie is 556mm, and the length of second longitudinal tie is 580mm, and the length of the 3rd longitudinal tie is 1450mm, and the length of the 4th longitudinal tie is 630mm.
After the length of the length of the cylinder diameter of direction machine, plumbing arm and four longitudinal ties set; When each wheel flutter is turned to all around the turning center rotation of same moment; Satisfy Ackermam theoretical steering characteristic; Each wheel flutter is in pure rolling as far as possible in steering procedure does not have the sideslip state, alleviates wear on tyres greatly, has increased safety, has reduced cost.
