A hydraulic working cylinder (2) on the left side of a front wheel is connected with a hydraulic working cylinder (2) on the right side of a rear wheel by using a hydraulic oil pipe and is communicated with one hydraulic main cylinder (1); and a hydraulic working cylinder (2) on the right side of the front wheel is connected with a hydraulic working cylinder (2) on the left side of the rear wheel by using a hydraulic oil pipe and is communicated with the other hydraulic main cylinder (1). After the hydraulic plunger type steering transmission device which has a simple structure and is extremely convenient to mount and manufacture is adopted, simultaneous steering of the front wheel and the rear wheel can be realized, so that the rear wheel can run following a running route of the front wheel when an automobile takes a turn; and convenience is brought for the automobile to turn around on a narrow road, so that the turning radius of the automobile is reduced, and the passage capacity of the automobile on a crooked road is improved.
Description
Technical field
The utility model relate to automobile steering system a kind of hydraulic plunger formula steering transmission linkage.
Background technology
The steering swivel system of automobile all adopts Jackstay type promotion steering swivel to realize turning to basically now, and this just makes front and back wheel not turn to simultaneously.
Summary of the invention
The purpose that the utility model relates to is in order to provide a kind of automobile front and back wheel when needs are turned to turn to simultaneously.
For realizing above-mentioned purpose, the utility model hydraulic plunger formula steering transmission linkage mainly is made up of hydraulic main cylinder, hydraulic cylinder, master cylinder push rod, tooth bar, gear, steering shaft, housing etc.Master cylinder push rod, gear and tooth bar are arranged in the housing; Gear is fixed on the steering shaft, tooth on the gear and the engagement of the tooth on the tooth bar, and tooth bar is processed in the middle part of master cylinder push rod; Hydraulic main cylinder is installed in the two ends of master cylinder push rod and remains on the same axial line with master cylinder push rod; One end of hydraulic cylinder is fixed on vehicle frame or vehicle body or the vehicle bridge position, front and back, and the other end connects track arm, connects hydraulic main cylinder and hydraulic cylinder with hydraulic oil pipe.
Further, can turn to smoothly simultaneously in order to implement front and back wheel, promptly during the front-wheel left-handed turning, the trailing wheel right-hand turning.Be connected with hydraulic oil pipe between the hydraulic cylinder of the hydraulic cylinder on the front-wheel left side of the utility model hydraulic plunger formula steering transmission linkage on the right of trailing wheel, and only communicate with one of them hydraulic main cylinder; Be connected with hydraulic oil pipe between the hydraulic cylinder on front-wheel the right and the hydraulic cylinder on the trailing wheel left side, and only communicate with another hydraulic main cylinder.
Further, can turn to for making trailing wheel, when the hydraulic cylinder of the utility model hydraulic plunger formula steering transmission linkage was installed on the trailing wheel, trailing wheel must have steering swivel and track arm.
The utility model hydraulic plunger formula steering transmission linkage simple in structure, install and make all very convenient.After having adopted hydraulic plunger formula steering transmission linkage, realized that front and back wheel can turn to simultaneously, made automobile trailing wheel when turning driving can seek the route running that front-wheel crosses; Be convenient to automobile simultaneously and on narrow road, reverse end for end, reduced the turn radius of automobile, improved the through performance of automobile on detour.
Description of drawings
Fig. 1 is the keystone configuration and the bonded assembly scheme drawing of the utility model hydraulic plunger formula steering transmission linkage.
The specific embodiment
The utility model hydraulic plunger formula steering transmission linkage mainly is made up of hydraulic main cylinder 1, hydraulic cylinder 2, master cylinder push rod 3, tooth bar 4, gear 5, steering shaft 6, housing 8 etc.Master cylinder push rod 3, gear 5 and tooth bar 4 are arranged in the housing 8; Gear 5 is fixed on the steering shaft 6; Tooth engagement on tooth on the gear 5 and the tooth bar 4, tooth bar 4 is processed in the middle part of master cylinder push rod 3, and hydraulic main cylinder 1 is installed in the two ends of master cylinder push rod 3 and remains on the same axial line with master cylinder push rod 3; One end of hydraulic cylinder 2 is fixed on vehicle frame or vehicle body or the vehicle bridge position, front and back, and the other end connects track arm 7.Be connected with hydraulic oil pipe 10 between the hydraulic cylinder 2 on the hydraulic cylinder 2 on front-wheel 9 left sides and trailing wheel 9 the right, and only communicate with one of them hydraulic main cylinder 1; Be connected with hydraulic oil pipe 10 between the hydraulic cylinder 2 on the hydraulic cylinder 2 on front-wheel 9 the right and trailing wheel 9 left sides, and only communicate with another hydraulic main cylinder 1.When the hydraulic cylinder 2 of hydraulic plunger formula steering transmission linkage was installed on the trailing wheel, trailing wheel must have steering swivel and track arm 7.
The utility model hydraulic plunger formula steering transmission linkage is after installing on the automobile; When turning driving; If turnon left, the bearing circle that turns left, master cylinder push rod 3 promotions this moment hydraulic main cylinder 1 on one side; Compression hydraulic main cylinder 1; Make the hydraulic oil in the hydraulic main cylinder 1 pass to the hydraulic cylinder 2 on the front-wheel left side and the hydraulic cylinder 2 on the right of the trailing wheel, make the hydraulic cylinder 2 on front-wheel 9 left sides and the hydraulic cylinder 2 on trailing wheel 9 the right promote steering swivels again, drive the near front wheel 9 left-hand rotations, off hind wheel 9 right-hand rotations.Simultaneously; The hydraulic main cylinder 1 of master cylinder push rod 3 pulling another sides; Make the space elongation in the hydraulic main cylinder 1 produce suction and the hydraulic oil backflow; Hydraulic oil in the hydraulic cylinder 2 on hydraulic cylinder 2 and trailing wheel 9 left sides on front-wheel 9 the right are and then refluxed, the hydraulic cylinder 2 on front-wheel 9 the right and the hydraulic cylinder 2 on trailing wheel 9 left sides are shortened and the pulling steering swivel, drive that off front wheel 9 turns left, left rear wheel 9 is turned right.Meanwhile, the connection horizontal pull bar on coaxial both sides also plays promotion at the hydraulic cylinder that shrinks 2 wheel 9 on one side, and this wheel 9 is on one side turned to.When turning driving, if right-hand corner, turning clockwise bearing circle, direction, the hydraulic main cylinder 1 that this moment, master cylinder push rod 3 promoted promote and direction, the hydraulic cylinder 2 of compression promotes and in the opposite direction when the rotation direction of the direction of compression, wheel 9 and turnon left.
