Abstract
The utility model relates to a multi-bridge steering transmission mechanism comprising a steering wheel, a steering column, a steering engine, a steering oscillation arm, a front bridge pull rod, a front steering bridge, a front bridge steering knuckle arm, a front steering trapezium and at least a group of rear steering group. The steering engine, the steering oscillation arm, the front bridge pull rod and a bridge space pull rod of the rear steering group, the rear steering bridge steering oscillation arm and the rear steering bridge pull rod are all arranged on the same side of a vehicle chassis to drive each bridge wheel to steer synchronously, thereby solving the problems of the prior multi-bridge steering transmission mechanism, such as large transmission error, inconsistent steering, and serious abrasion of tyres.
Description
Technical field: the utility model belongs to steering mechanism of motor vehicle, especially relates to a kind of many bridges steering gear.
Background technology: at present, what known many bridges steering gear adopted is that and arranged on left and right sides is provided with the connecting rod transmission, left side pull bar one end links to each other with the swing arm that turns on the steering box, other end direct connection is on the track arm of first steeraxle, and pull bar two ends, right side link to each other with the track arm of back steeraxle with the swing arm that turns to of back steeraxle respectively, drive many bridges by the both sides jointed gear unit and turn to, complex structure, exist driving error big when turning to, turn to inharmonious, defective such as wear on tyres is serious.
Summary of the invention: the purpose of this utility model is in order to overcome existing many bridges steering gear complex structure, the steerage gear error is big, turn to defectives such as inharmonious, that wear on tyres is serious, and a kind of simple in structure, many bridges steering gear that the steerage gear error is little is provided.
The utility model by bearing circle, Steering gear, steering box, turn to swing arm, turn to group to form behind propons pull bar, front steering axle, front axle steering knuckle arm, propons steering trapezium and at least one group, after turn to group control back steeraxle two-wheeled to rotate synchronously.After turn to group to comprise that pull bar between bridge, back steeraxle turn to swing arm, back steeraxle pull bar, back steeraxle, back steeraxle track arm, back steeraxle steering trapezium.Steering box, turn to pull bar between swing arm, propons pull bar, bridge, back steeraxle to turn to swing arm and back steeraxle pull bar to be arranged in the same side of automobile chassis frame, between bridge pull bar one end with turn to swing arm hinged, the other end turns to swing arm hinged with the back steeraxle, and back steeraxle turns to the swing arm other end hinged with back steeraxle pull bar.
The beneficial effect of utility model is, pull bar, propons pull bar and back steeraxle pull bar turn to the line of centres of swing arm swing not parallel with the back steeraxle between bridge, but angled, and the back steeraxle turns to and keeps a stable drive ratio between the swing arm.Each back steeraxle turns to the length of swing arm and arranges identical with the relative position of steeraxle like this, make the back steeraxle turn to swing arm identical with the transmitting ratio of track arm, realize the dynam between each steering wheel angle and the coupling of mechanical property, it is big to have solved existing many bridges steering gear driving error, turn to inharmonious, the problem that wear on tyres is serious.
