Damping type locomotive

Abstract

The invention discloses a damping type locomotive. A windward inner cylinder is installed in an outer cylinder, and the bottom of the windward inner cylinder is provided with a grounding damping piece. When the inner cylinder moves down to be arranged on the grounding damping piece in a sleeving mode, a damping gap is formed between the inner cylinder and the grounding damping piece in the transverse direction. The inner cylinder is sleeved with the outer cylinder through a piston, hydraulic oil is arranged in the space relative to the piston moving down in the outer cylinder, and the space communicates with the inner cylinder. When the inner cylinder moves down to be arranged on the grounding damping piece in the sleeving mode, the hydraulic oil in the outer cylinder can enter the inner cylinder only through the damping gap, and therefore effective damping can be formed; since the grounding damping piece is located at the bottom in the outer cylinder, when the grounding damping pieceenters the lower port of the inner cylinder, damping starts to be formed, the height of the grounding damping piece is adjusted, the damping starting portion can be set, the grounding of a damper during driving on an uneven road surface is avoided, the driving safety is improved, controllability is ensured, the service life of the damper is easily ensured, the aims of preventing grounding and protecting the parts against grounding damage can be realized only with a small improvement (only by adding one grounding damping piece), and the controllability, comfort, stability, safety and reliability are improved.

Description

technical field [0001] The invention relates to a motor vehicle component and a motor vehicle, in particular to a shock absorber and a three-wheel motorcycle. Background technique [0002] Shock absorber is a necessary part of a motor vehicle. The structure affects the handling and comfort of the vehicle. Whether the performance is stable or not is directly related to the safety, reliability, comfort and handling of the vehicle. Existing shock absorbers generally include an inner cylinder, an outer cylinder and a damping spring; the inner cylinder is generally sleeved on the outer cylinder through a piston (the piston reciprocates with the inner cylinder in the outer cylinder), and the space between the outer cylinder and the piston is filled with hydraulic pressure. Oil, when the inner cylinder reciprocates, the hydraulic oil forms a flow in this space and the inner cylinder, which plays the role of lubrication and limited liquid damping. In fact, because the diameter of th...

Problems solved by technology

Existing shock absorbers generally include an inner cylinder, an outer cylinder and a damping spring; the inner cylinder is generally sleeved on the outer cylinder through a piston (the piston reciprocates with the inner cylinder in the outer cylinder), and the space between the outer cylinder and the piston is filled with hydraulic pressure. Oil, when the inner cylinder reciprocates, the hydraulic oil forms a flow in this space and the inner cylinder, which plays the role of lubrication and limited liquid damping. In fact, because the diameter of the inner cylinder and the outer cylinder is not much different, the damping effect is It is also extremely limited and cannot form an effective compression damping force

[0003] In the prior art, in order to save the overall cost of the three-wheeled motorcycle, one of the front shock absorbers adopts the aforementioned structure. The shock absorber of this structure has a better effect of restoring damping, but it cannot form effective compression damping, as shown in the figure As shown by the solid line, therefore, on a slightly larger uneven road surface, the shock absorber will bottom out, seriously affecting the handling, comfort and safety reliability of the vehicle
