Description

Technical Field

[0001] The invention relates to the technical field of vehicles, and in particular discloses a two-link type lateral thrust rod structure and a vehicle. Background Art

[0002] The connection between the axle and the body of a rigid-bridge off-road vehicle usually adopts a 5-link structure, in which four links are used to limit the front and rear displacement of the axle relative to the body, and there is also a diagonal rod, which is usually called a thrust rod, to limit the lateral swing of the body relative to the axle and play a stabilizing role.

[0003] Currently, the commonly used thrust rod is the Panhard connecting rod. Since the end of the connecting rod swings in an arc shape, when the vehicle body fluctuates with the road conditions, it will cause some lateral offset of the vehicle body relative to the axle. The greater the fluctuation of the vehicle body, the greater the offset, which not only reduces comfort but also poses a safety hazard to the vehicle traveling at high speeds.

[0004] Some vehicles also use Watt's link. Although the Watt's link can solve the problem of lateral swing during ups and downs, the stroke of the Watt's link is too small, which will limit the suspension travel for off-road vehicles. Summary of the invention

[0004] In order to solve the problem of lateral swing of the vehicle body relative to the axle when a hard-bridge off-road vehicle encounters ups and downs while driving at high speed, and taking into account that the suspension travel will not be limited, the present invention provides a two-link type lateral thrust rod structure and a vehicle.

[0005] To achieve the above-mentioned purpose, the present invention provides a two-link type lateral thrust rod structure, including: a central sliding rod, the central sliding rod is configured with a connection point; a first sliding connector, a second sliding connector, the first sliding connector and the second sliding connector are both provided with a central hole, and are slidingly connected to the central sliding rod through the central hole; a first two-link, the first two-link and the first sliding connector are rotatably connected; a second two-link, the second two-link and the first sliding connector are rotatably connected.

[0006] Furthermore, the first two connecting rods include a first upper connecting rod and a first lower connecting rod, and a small pull rod is respectively arranged in the middle of the first upper connecting rod and the first lower connecting rod, and the small pull rod is rotatably connected to the first upper connecting rod and the first lower connecting rod, and the other ends of the small pull rods are rotatably connected to the connection points on the central sliding rod.

[0007] Furthermore, the second second connecting rod includes a second upper connecting rod and a second lower connecting rod, and one end of the second upper connecting rod and the second lower connecting rod connected to the second sliding connector is provided with a gear sleeve, and the gear sleeve is provided with a key slot, and the second upper connecting rod and the second lower connecting rod are fixedly connected through the key slot and the gear.

[0008] Furthermore, the small pull rods are arranged at the same position, and the first upper pull rod and the first lower pull rod are symmetrical about the central sliding rod.

[0009] Furthermore, the second upper connecting rod and the second lower connecting rod are symmetrical about the central sliding rod when they are fixedly connected to the gear.

[0010] The technical solution provided in the present application above, compared with the prior art, includes at least the following beneficial effects or advantages: when the hard-bridge off-road vehicle equipped with the present invention is traveling at high speed on an undulating road surface and the body of the vehicle moves up and down relative to the axle, the ends of the first and second connecting rods are always in two parallel planes, that is, the body of the vehicle 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 solution of the present invention has a larger travel range.

[0011] The present invention provides a vehicle, comprising the above-mentioned two-link type lateral thrust rod structure. BRIEF DESCRIPTION OF THE DRAWINGS
