Technical field
The present invention relates to the technical field of a vehicle, and specifically discloses a two-link type transverse thrust rod structure and a vehicle.
Background technology
The connection between the axle and the body of the hard-bridge off-road vehicle usually adopts a 5-link structure, of which there are four connecting rods to limit the front and rear displacement of the axle relative to the body, and a diagonal rod, which is what we usually call a thrust rod, to limit the lateral swing of the body relative to the axle and play a stabilizing role.
At present, the commonly used thrust rod is the Panhard connecting rod, because the end swing of the connecting rod is arc-shaped, so when the body undulates with the road conditions, the body will cause the body to have some lateral deviation relative to the axle, the greater the body undulation, the greater the offset, not only reduce the comfort, but even bring safety hazards to the high-speed vehicle.
There are also vehicles that use the Watt linkage, although the Watt linkage can solve the problem of lateral oscillation when undulating, but the Watt linkage travel is too small, which will limit the suspension travel for off-road vehicles.
Contents of the invention
In order to solve the problem that the body of the hard axle off-road vehicle encounters ups and downs when it encounters ups and downs at high speed, and considering that the suspension travel will not be limited, the invention provides a two-link type transverse thrust rod structure and the vehicle.
In order to achieve the above purpose, the invention provides a two-link type transverse thrust rod structure, comprising: a central slide rod, and the central slide rod is configured with a connecting point; the first sliding connector, the second sliding connector, the first sliding connector and the second sliding connector are provided with a center hole, and are sliding sleeved with the central slide rod through the center hole; the first two connecting rods are rotatably connected with the first sliding connectors; the second two connecting rods and the first sliding connector are rotatably connected.
Further, the first second connecting rod comprises a first upper connecting rod and a first lower connecting rod, a small pull rod is respectively arranged in the middle part of the first upper connecting rod and the first lower connecting rod, and the small pull rod is rotatably connected with the first upper connecting rod and the first lower connecting rod, and the other end of the small pull rod is rotatably connected with the connecting point on the central slide rod.
Further, the second second connecting rod comprises a second upper connecting rod and a second lower connecting rod, a gear shaft sleeve is arranged at one end of the second upper connecting rod and the second lower connecting rod and the second sliding connector, a keyway is arranged with the gear shaft sleeve, and the second upper connecting rod and the second lower connecting rod are fixedly connected through a keyway and a gear.
Further, the small pull rod is arranged in the same position, and the first upper pull rod and the first lower pull rod are symmetrical with respect to the central slide bar.
Further, the second upper connecting rod and the second lower connecting rod are fixedly connected with the gear with respect to the central slide rod symmetrically.
In the technical scheme provided above, compared with the prior art, at least the following beneficial effects or advantages are included: the hard bridge off-road vehicle with the present invention is installed, when the body moves up and down relative to the axle when driving at high speed on the undulating road surface, the end of the first two connecting rods and the end of the second two connecting rods are always in two parallel planes, that is to say, the body has no lateral displacement relative to the axle, so as to improve the comfort and safety of the vehicle; At the same time, the technical scheme of the present invention has a large stroke.
The present invention provides a vehicle, comprising a two-link type transverse thrust rod structure described above.
